-END_HEAD_VARS=Yioop Wiki Syntax=
-
-: Wiki syntax is a lightweight way to markup a text document so that
-it can be formatted and drawn nicely by Yioop.
-This page briefly describes the wiki syntax supported by Yioop.
-
-==Headings==
-: In wiki syntax headings of documents and sections are written as follows:
-
-<nowiki>
-=Level1=
-==Level2==
-===Level3===
-====Level4====
-=====Level5=====
-======Level6======
-</nowiki>
-
-and would look like:
-
-=Level1=
-==Level2==
-===Level3===
-====Level4====
-=====Level5=====
-======Level6======
-
-==Paragraphs==
-: In Yioop two new lines indicates a new paragraph. You can control
-the indent of a paragraph by putting colons followed by a space in front of it:
-
-<nowiki>
-: some indent
-
-:: a little more
-
-::: even more
-
-:::: that's sorta crazy
-</nowiki>
-
-which looks like:
-
-: some indent
-
-:: a little more
-
-::: even more
-
-:::: that's sorta crazy
-
-==Horizontal Rule==
-: Sometimes it is convenient to separate paragraphs or sections with a horizontal
-rule. This can be done by placing four hyphens on a line by themselves:
-<nowiki>
-----
-</nowiki>
-This results in a line that looks like:
-----
-
-==Text Formatting Within Paragraphs==
-: Within a paragraph it is often convenient to make some text bold, italics,
-underlined, etc. Below is a quick summary of how to do this:
-===Wiki Markup===
-{|
-|<nowiki>''italic''</nowiki>|''italic''
-|-
-|<nowiki>'''bold'''</nowiki>|'''bold'''
-|-
-|<nowiki>'''''bold and italic'''''</nowiki>|'''''bold and italic'''''
-|}
-
-===HTML Tags===
-: Yioop also supports several html tags such as:
-{|
-|<nowiki><del>delete</del></nowiki>|<del>delete</del>
-|-
-|<nowiki><ins>insert</ins></nowiki>|<ins>insert</ins>
-|-
-|<nowiki><s>strike through</s> or
-<strike>strike through</strike> </nowiki>|<s>strike through</s>
-|-
-|<nowiki><sup>superscript</sup> and
-<sub>subscript</sub></nowiki>|<sup>superscript</sup> and
-<sub>subscript</sub>
-|-
-|<nowiki><tt>typewriter</tt></nowiki>|<tt>typewriter</tt>
-|-
-|<nowiki><u>underline</u></nowiki>|<u>underline</u>
-|}
-
-===Spacing within Paragraphs===
-: The HTML entity
-<nowiki> </nowiki>
-can be used to create a non-breaking space. The tag
-<nowiki><br></nowiki>
-can be used to produce a line break.
-
-==Preformatted Text and Unformatted Text==
-: You can force text to be formatted as you typed it rather
-than using the layout mechanism of the browser using the
-<nowiki><pre>preformatted text tag.</pre></nowiki>
-Alternatively, a sequence of lines all beginning with a
-space character will also be treated as preformatted.
-
-: Wiki markup within pre tags is still parsed by Yioop.
-If you would like to add text that is not parsed, enclosed
-it in <tt><`mbox{nowiki}`> </`mbox{nowiki}`></tt> tags.
-
-==Styling Text Paragraphs==
-: Yioop wiki syntax offers a number of templates for
-control the styles, and alignment of text for
-a paragraph or group of paragraphs:<br />
-`{{`left| some text`}}`,<br /> `{{`right| some text`}}`,<br />
-and<br />
-`{{`center| some text`}}`<br /> can be used to left-justify,
-right-justify, and center a block of text. For example,
-the last command, would produce:
-{{center|
-some text
-}}
-If you know cascading style sheets (CSS), you can set
-a class or id selector for a block of text using:<br />
-`{{`class="my-class-selector" some text`}}`<br />and<br />
-`{{`id="my-id-selector" some text`}}`.<br />
-You can also apply inline styles to a block of text
-using the syntax:<br />
-`{{`style="inline styles" some text`}}`.<br />
-For example, `{{`style="color:red" some text`}}` looks
-like {{style="color:red" some text}}.
-
-==Lists==
-: The Yioop Wiki Syntax supported of ways of listing items:
-bulleted/unordered list, numbered/ordered lists, and
-definition lists. Below are some examples:
-
-===Unordered Lists===
-<nowiki>
-* Item1
-** SubItem1
-** SubItem2
-*** SubSubItem1
-* Item 2
-* Item 3
-</nowiki>
-would be drawn as:
-* Item1
-** SubItem1
-** SubItem2
-*** SubSubItem1
-* Item 2
-* Item 3
-
-===Ordered Lists===
-<nowiki>
-# Item1
-## SubItem1
-## SubItem2
-### SubSubItem1
-# Item 2
-# Item 3
-</nowiki>
-# Item1
-## SubItem1
-## SubItem2
-### SubSubItem1
-# Item 2
-# Item 3
-
-===Mixed Lists===
-<nowiki>
-# Item1
-#* SubItem1
-#* SubItem2
-#*# SubSubItem1
-# Item 2
-# Item 3
-</nowiki>
-# Item1
-#* SubItem1
-#* SubItem2
-#*# SubSubItem1
-# Item 2
-# Item 3
-
-===Definition Lists===
-<nowiki>
-;Term 1: Definition of Term 1
-;Term 2: Definition of Term 2
-</nowiki>
-;Term 1: Definition of Term 1
-;Term 2: Definition of Term 2
-
-==Tables==
-: A table begins with {`|`  and ends with `|`}. Cells are separated with | and
-rows are separated with |- as can be seen in the following
-example:
-<nowiki>
-{|
-|a||b
-|-
-|c||d
-|}
-</nowiki>
-{|
-|a||b
-|-
-|c||d
-|}
-Headings for columns and rows can be made by using an exclamation point, !,
-rather than a vertical bar |. For example,
-<nowiki>
-{|
-!a!!b
-|-
-|c||d
-|}
-</nowiki>
-{|
-!a!!b
-|-
-|c||d
-|}
-Captions can be added using the + symbol:
-<nowiki>
-{|
-|+ My Caption
-!a!!b
-|-
-|c||d
-|}
-</nowiki>
-{|
-|+ My Caption
-!a!!b
-|-
-|c||d
-|}
-Finally, you can put a CSS class or style attributes (or both) on the first line
-of the table to further control how it looks:
-<nowiki>
-{| class="wikitable"
-|+ My Caption
-!a!!b
-|-
-|c||d
-|}
-</nowiki>
-{| class="wikitable"
-|+ My Caption
-!a!!b
-|-
-|c||d
-|}
-Within a cell attributes like align, valign, styles, and class can be used. For
-example,
-<nowiki>
-{|
-| style="text-align:right;"| a| b
-|-
-| lalala | lalala
-|}
-</nowiki>
-{|
-| style="text-align:right;"| a| b
-|-
-| lalala | lalala
-|}
-
-==Math==
-
-: Math can be included into a wiki document by either using the math tag:
-<nowiki>
-<math>
-\sum_{i=1}^{n} i = frac{(n+1)(n)}{2}
-</math>
-</nowiki>
-
-<math>
-\sum_{i=1}^{n} i = frac{(n+1)(n)}{2}
-</math>
-
-or by enclosing the math in backticks:
-
-<pre>
-`[[1, -2],[3,4]]`
-</pre>
-
-`[[1, -2],[3,4]]`.
-
-Rendering of math is done using [[https://www.mathjax.org/|MathJax]], making us of the [[https://en.wikipedia.org/wiki/ASCIIMathML|ASCIImathml]] extensions.
-
-==Links and Relationships==
-: A hypertext link to another document can be inserted into a wiki page using
-the chain link icon in the GUI. Alternatively, there are several techniques
-for inserting a link into a page depending on whether the link is to a page
-within the same wiki group, is a link to a page on a different wiki
-group, or is a link to a different website. In addition to normal
-hypertext links, Yioop also supports relationship links.
-
-'''Intra-Group Wiki Links''' use the syntax:
-<nowiki>
-[[name_of_wiki_page]]
-or
-[[name_of_wiki_page|text for the link]]
-or
-[[name_of_wiki_page#heading_or_id_on_page|text for the link]]
-</nowiki>
-for example, to make a link to this Syntax page one could write,
-<nowiki>
-[[Syntax|Yioop Wiki Syntax Page]]
-</nowiki>
-which would look like,
-
-[[Syntax|Yioop Wiki Syntax Page]]
-
-'''Inter-Group Wiki Links''' use the syntax:
-<nowiki>
-[[name_of-group@name_of_wiki_page|text for the link]]
-</nowiki>
-
-'''Different Website Links''' use the syntax:
-<nowiki>
-[[website_url|text for the link]]
-</nowiki>
-
-: Relationships are a generalized form of link. They are used to express
-a more complicated linking between two wiki pages and have the syntax:
-
-<nowiki>
-[[relationship_type|wiki_page_name|text for the link]]
-</nowiki>
-
-: In the navigation dropdown for a Yioop wiki page there are items for
-what links to the current page and what relates to the current page
-based on the links and relationships a page belongs to.
-
-==Recent Places Dropdowns==
-: You can add a dropdown that can allow users to navigate to recently visited
-wiki pages using the syntax:
-
-<sub>`[`{recent_places}]</sub>
-
-This looks like:
-
-[{recent_places}]
-
-==Adding Resources to a Page==
-
-: Yioop wiki syntax supports adding search bars, audio, images, and video to a
-page. The magnifying class edit tool icon can be used to add a search bar via
-the GUI. This can also be added by hand with the syntax:
-<nowiki>
-{{search:default|size:small|placeholder:Search Placeholder Text}}
-</nowiki>
-This syntax is split into three parts each separated by a vertical bar |. The
-first part search:default means results from searches should come from the
-default search index. You can replace default with the timestamp of a specific
-index or mix if you do not want to use the default. The second group size:small
-indicates the size of the search bar to be drawn. Choices of size are small,
-medium, and large. Finally, placeholder:Search Placeholder Text indicates the
-grayed out background text in the search input before typing is done should
-read: Search Placeholder Text. Here is what the above code outputs:
-
-{{search:default|size:small|placeholder:Search Placeholder Text}}
-
-: Image, video and other media resources can be associated with a page by dragging
-and dropping them in the edit textarea or by clicking on the link click to select
-link in the gray box below the textarea. This would add wiki code such as
-
-<sub>((resource`:`myphoto.jpg|Resource Description))</sub>
-
-to the page. Only saving the page will save this code and upload the resource to
-the server. In the above ''myphoto.jpg'' is the resource that will be inserted and
-Resource Description is the alternative text to use in case the viewing browser
-cannot display jpg files. To add a resource
-from a different wiki page belonging to the same group to the current wiki
-page one can use a syntax like:
-
-<sub>((resource`:`Documentation:ConfigureScreenForm1.png|The work directory form))</sub>
-
-Here Documentation would be the page and ConfigureScreenForm1.png the resource.
-You can also insert resources from a data-string using ''resource-data'' rather than
-''resource''. For example:
-
-<sub>((resource-data`:`image/jpeg;base64,/9j/4AAQSkZJRg...rest of image data...|Seekquarry Logo))</sub>
-
-could be used to inline an image like:
-
-((resource-data:image/jpeg;base64,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|The Seekquarry Logo))
-
-be aware though that the default maximum wiki page size is 512Kb (this can be set in src/configs/Config.php).
-
-: Sometimes it is useful to edit the basic resource link
-above to make a link which is a thumbnail of the resource which points to a
-separate page containing that resource. This can be done using the syntax:
-
-<sub>((resource-thumb`:`myphoto.jpg|Resource Description))</sub>
-
-: Similarly, by default for resources like PDFs, epub's, etc., the resource tag inlines
-the whole resource into the page, if instead one wants a clickable link to a page where
-the resource is displayed one can use the syntax:
-
-<sub>((resource-link`:`my_document.pdf|Resource Description))</sub>
-
-: Comma separated value files (.csv or CSV files) are inlined into a page as a table. Which rows and columns of the CSV to present in this table can be controlled by the resource line. The general format for including
-a CSV resource is:
-
-<sub> ((resource`:`resource_name.csv#config#top_left_cell#bottom_right_cell|Resource Description))</sub>
-
-For example,
-
-<sub>((resource`:`resource_name.csv##B2#C3|Resource Description))</sub>
-
-might output
-
-((resource-data:text/csv;base64,LCwsLAosLTIsMywsCiw1LDQsLAosLCwsCiwsLCwK##B2#C3|Example CSV with Headings))
-
-I.e., just the portion of the CSV given by the rectangle between the cells B2 and C3. Using a config directive we can omit the spreadsheet row and column headings as follows:
-
-<sub>((resource`:`resource_name.csv#noheadings#B2#C3|Resource Description)) </sub>
-
-which might output
-
-
-((resource-data:text/csv;base64,LCwsLAosLTIsMywsCiw1LDQsLAosLCwsCiwsLCwK#noheadings#B2#C3|Example CSV without Headings))
-
-CSV spreadsheet files can also be used to output a variety of charts. The general format for the command to insert a chart resource is:
-
-<sub>((resource-chart_type`:`resource_name.csv#char_config#x_start#x_end#y_start#y_end|Resource Description))</sub>
-
-Here ''chart_type'' can be one of ''bargraph'',  ''linegraph'', or ''pointgraph''. For example, one might have a line like:
-
-<sub>((resource-bargraph`:`resource_name.csv##B1#B4#C1#C4|Quadratic Function)) </sub>
-
-which could produce a chart like
-
-((resource-bargraph:##(1,1)#(2,4)#(3,9)#(4,16)|Quadratic Function))
-
-In the above example, the values for the `x` coordinates would come from the cells B1, B2, B3, B4 from
-''resource_name.csv '' and the values for the `y` coordinates would come from cells C1, C2, C3, C4 from
-''resource_name.csv ''. Alternatively, rather than use a CSV to get out data we can just list the points we want to plot with a command like:
-
-<sub>((resource-bargraph`:`##(1,1)#(2,4)#(3,9)#(4,16)|Quadratic Function))</sub>
-
-==Manipulating Page Resources==
-
-: A list of media that have already been associated with
-a page appears under the Page Resource heading below the textarea. This
-table allows the user to rename and delete resources as well as insert the
-same resource at multiple locations within the same document.
-
-: The resources section of the edit page can be thought of as similar to
-a folder in Windows or MacOS. One can have subfolders of the resource folder.
-
-: The '''Places''' dropdown at the top of the '''Page Resource''' section allows one to navigate
-these folders.
-
-: The '''Filter''' textfield lets you enter a search string.
-Clicking '''Go''' then shows only those resources
-which contain that search string in their title.
-
-: The '''Clip Folder''' dropdown is used to copy files between folders and pages.
-Its current value is the folder that the '''Clip Copy''' buttons next to resources
-will copy their resource to when clicked. You can set the '''Clip Folder''' to
-the current folder using the dropdown, then  move to the page and folder that
-you would like to copy stuff from and click the '''Clip Copy''' button of the
-desired resource.
-
-: The '''Name''', '''Size''', '''Modified''' header links above the resources list
-control the sort order for the resource list. If a page is a media list page,
-then even in read mode, the sort order selected is remembered when drawing the
-media list.
-
-: The '''Actions''' drop can be used to create new folders, new text files, and new csv
-text files within the current page resource folder. These are initial named beginning
-with ''untitled'' followed by some number, and if applicable a file extension.
-
-: Resources entries for the resources list consist first of an icon, followed by a textfield
-with a name for the resource, followed by buttons for actions that can be done to that resource
-(Rename, Add to Page, Clip Copy), followed by a link [X], which can be used to delete the resource.
-If a resource is editable the icon will look like a plus sign together with a pencil. Clicking
-on the icon will then let you edit the resource.
-
-===Text and CSV Resources===
-: For normal text files clicking edit will bring up a textarea with the context of the text to edit.
-For CSV (comma separated value) files this will present the file as an editable spreadsheet.
-Yioop spreadsheets can have equation much like Excel spreadsheets. Clicking on a cell lets one
-edit its contents. For example, if in the cell A3
-one entered the equation:
- = A1+A2
-then clicking out of the cell would cause it to refresh with the value of the sum of the contents of
-cells A1 and A2. In addition, to the standard arithmetic operators ['*', '/', '+', '-', '%'], the
-spreadsheet expressions can use float or integer literals, and can make use of the following table
-of built-in functions:
-
-{| class="wikitable"
-!Function Name!!Description
-|-
-!avg(x1,...,xn), avg(x1:xn)|| computes average of values of cells listed as arguments
-|-
-!ceil(x)|| rounds the value of x up to nearest integer
-|-
-!cell(i,j)|| returns the contents of the cell with column name of letter j, and row name i. For example, cell(2,'B') would return the contents of cell B2.
-|-
-!col(value, search_row, start_col, end_col)|| searches the row ''search_row'' between the columns
-''start_col'', ''end_col'' for ''value''. Returns the column name where this value was found or -1 if not found.
-For example, col(3, 2, "B", "D") might return C if the cell C2 had value 3.
-|-
-!exp(x)|| computes `e^x`
-|-
-!floor(x)|| rounds the value of x down to the nearest integer
-|-
-!log(x)|| computes `log x`
-|-
-!min(x1,...,xn), min(x1:xn)|| computes minimum value of cells listed as arguments
-|-
-!max(x1,...,xn), max(x1:xn)|| computes maximum value of cells listed as arguments
-|-
-!pow(x,y)|| computes `x^y`
-|-
-!row(value, search_col, start_row, end_row)|| searches the column ''search_col''
-between the rows ''start_row'', ''end_row'' for ''value''.
-Returns the row name where this value was found or -1 if not found.
-For example, row(3, "C", "1", "5") might return 2 if the cell C2 had value 3.
-|-
-!sqrt(x)|| computes `sqrt(x)`
-|-
-!sum(x1,...,xn), sum(x1:xn)|| computes sum of values of cells listed as arguments
-|-
-!username()|| returns username of the person using this CSV file
-|}
-
-===HTML, PDF and EPub Resources===
-: How HTML, PDF, EPub resources included on a page render depends on how the Yioop wiki software
-has been configured. If no special configuration has been done, then HTML and PDF documents
-will bbe rendered in an <iframe> tag within the current wiki page. In the EPub, case a link
-to download the resource will be given. If the wiki software detects the presence of the
-file APP_DIR/scripts/pdf.js ([[https://en.wikipedia.org/wiki/PDF.js|PDF.js]])
-or APP_DIR/scripts/epub.js ([[https://github.com/futurepress/epub.js|epub.js]]), the wiki
-system will render the resource in a Javascript viewer and will do things like remember reading
-position.
-
-
-===Video and Audio Resources===
-
-: Not all browsers support the same video and audio formats for playback. For this reason
-it sometimes is useful to have multiple video resources for the same video. For example,
-you might have a .ogv and .vp8 version of the same video recording. In read (non-edit)
-mode, the Yioop wiki system displays only one link for video or audio files that have
-the same name except for extension. It then includes the grouped file as separated <source>
-tags within either the <video> or <audio> html tag used to render the item in the browser.
-In this way, you can make your media take best advantages to whatever capabilities your
-client's browser has. If you don't feel like recoding your media in such a fancy way, a safe
-rule of thumb is that .mp3 audio will playback in all modern browser, and that .mp4 video
-will playback in all modern browser.
-
-: For video it is sometimes useful to add a subtitle or caption track. Yioop wiki supports
-[[https://en.wikipedia.org/wiki/WebVTT|WebVTT]] format subtitles and captions. To see how
-Yioop wiki makes use of these files, suppose you included a resource ''foo.mp4'' in your
-wiki pages, and you also had a file named ''foo-captions-en-US.vtt'' then when the HTML
-page is generated from your wiki page, a <track> tag for the caption file would be added
-to the <video> tag. A user seeing this page would then see in the video player a closed caption
-symbol and be able to turn on/off (defaults off) the English captions. If you wanted
-named the file ''foo-subtitles-en-US.vtt'' instead, then Yioop wiki would include it as a
-subtitles track (defaults on). You can add captions/subtitle files for as many languages as
-desired.
-
-: When viewing the page resources for a page in edit mode, one can see one file/resource and
-no grouping of resources by name is done. In this way you can keep track of exactly what
-resources are available for a page.
-
-==Page Settings, Page Type==
-
-: In edit mode for a wiki page, next to the page name, is a link [Settings].
-Clicking this link expands a form which can be used to control global settings
-for a wiki page.  This form contains a drop down for the page type, another
-drop down for the type of border for the page in non-logged in mode,
-a checkbox for whether a table of contents should be auto-generated from level 2
-and level three headings and then text
-fields or areas for the page title, author, meta robots, and page description.
-Beneath this one can specify another wiki page to be used as a header for this
-page and also specify another wiki page to be used as a footer for this page.
-
-: The contents of the page title is displayed in the browser title when the
-wiki page is accessed with the  Activity Panel collapsed or when not logged in.
-Similarly, in the collapsed or not logged in mode, if one looks as the HTML
-page source for the page,  in the head of document, <meta> tags for author,
-robots, and description are set according to these fields. These fields can
-be useful for search engine optimization. The robots meta tag can be
-used to control how search engine robots index the page. Wikipedia has more information on
-[[https://en.wikipedia.org/wiki/Meta_element|Meta Elements]].
-
-: The '''Standard''' page type treats the page as a usual wiki page.
-
-: '''Page Alias''' type redirects the current page to another page name. This can
-be used to handle things like different names for the same topic or to do localization
-of pages. For example, if you switch the locale from English to French and
-you were on the wiki page dental_floss when you switch to French the article
-dental_floss might redirect to the page dentrifice.
-
-: '''Media List''' type means that the page, when read, should display just the
-resources in the page as a list of thumbnails and links. These links for the
-resources go to a separate pages used to display these resources.
-This kind of page is useful for a gallery of
-images or a collection of audio or video files.
-
-: '''Presentation''' type is for a wiki page whose purpose is a slide presentation. In this mode,
-....
-on a line by itself is used to separate one slide. If presentation type is a selected a new
-slide icon appears in the wiki edit bar allowining one to easily add new slides.
-When the Activity panel is not collapsed and you are reading a presentation, it just
-displays as a single page with all slides visible. Collapsing the Activity panel presents
-the slides as a typical slide presentation using the
+END_HEAD_VARS=Yioop Wiki Syntax=
+
+: Wiki syntax is a lightweight way to markup a text document so that
+it can be formatted and drawn nicely by Yioop.
+This page briefly describes the wiki syntax supported by Yioop.
+
+==Headings==
+: In wiki syntax headings of documents and sections are written as follows:
+
+<nowiki>
+=Level1=
+==Level2==
+===Level3===
+====Level4====
+=====Level5=====
+======Level6======
+</nowiki>
+
+and would look like:
+
+=Level1=
+==Level2==
+===Level3===
+====Level4====
+=====Level5=====
+======Level6======
+
+==Paragraphs==
+: In Yioop two new lines indicates a new paragraph. You can control
+the indent of a paragraph by putting colons followed by a space in front of it:
+
+<nowiki>
+: some indent
+
+:: a little more
+
+::: even more
+
+:::: that's sorta crazy
+</nowiki>
+
+which looks like:
+
+: some indent
+
+:: a little more
+
+::: even more
+
+:::: that's sorta crazy
+
+==Horizontal Rule==
+: Sometimes it is convenient to separate paragraphs or sections with a horizontal
+rule. This can be done by placing four hyphens on a line by themselves:
+<nowiki>
+----
+</nowiki>
+This results in a line that looks like:
+----
+
+==Text Formatting Within Paragraphs==
+: Within a paragraph it is often convenient to make some text bold, italics,
+underlined, etc. Below is a quick summary of how to do this:
+===Wiki Markup===
+{|
+|<nowiki>''italic''</nowiki>|''italic''
+|-
+|<nowiki>'''bold'''</nowiki>|'''bold'''
+|-
+|<nowiki>'''''bold and italic'''''</nowiki>|'''''bold and italic'''''
+|}
+
+===HTML Tags===
+: Yioop also supports several html tags such as:
+{|
+|<nowiki><del>delete</del></nowiki>|<del>delete</del>
+|-
+|<nowiki><ins>insert</ins></nowiki>|<ins>insert</ins>
+|-
+|<nowiki><s>strike through</s> or
+<strike>strike through</strike> </nowiki>|<s>strike through</s>
+|-
+|<nowiki><sup>superscript</sup> and
+<sub>subscript</sub></nowiki>|<sup>superscript</sup> and
+<sub>subscript</sub>
+|-
+|<nowiki><tt>typewriter</tt></nowiki>|<tt>typewriter</tt>
+|-
+|<nowiki><u>underline</u></nowiki>|<u>underline</u>
+|}
+
+===Spacing within Paragraphs===
+: The HTML entity
+<nowiki> </nowiki>
+can be used to create a non-breaking space. The tag
+<nowiki><br></nowiki>
+can be used to produce a line break.
+
+==Preformatted Text and Unformatted Text==
+: You can force text to be formatted as you typed it rather
+than using the layout mechanism of the browser using the
+<nowiki><pre>preformatted text tag.</pre></nowiki>
+Alternatively, a sequence of lines all beginning with a
+space character will also be treated as preformatted.
+
+: Wiki markup within pre tags is still parsed by Yioop.
+If you would like to add text that is not parsed, enclosed
+it in <tt><`mbox{nowiki}`> </`mbox{nowiki}`></tt> tags.
+
+==Styling Text Paragraphs==
+: Yioop wiki syntax offers a number of templates for
+control the styles, and alignment of text for
+a paragraph or group of paragraphs:<br />
+`{{`left| some text`}}`,<br /> `{{`right| some text`}}`,<br />
+and<br />
+`{{`center| some text`}}`<br /> can be used to left-justify,
+right-justify, and center a block of text. For example,
+the last command, would produce:
+{{center|
+some text
+}}
+If you know cascading style sheets (CSS), you can set
+a class or id selector for a block of text using:<br />
+`{{`class="my-class-selector" some text`}}`<br />and<br />
+`{{`id="my-id-selector" some text`}}`.<br />
+You can also apply inline styles to a block of text
+using the syntax:<br />
+`{{`style="inline styles" some text`}}`.<br />
+For example, `{{`style="color:red" some text`}}` looks
+like {{style="color:red" some text}}.
+
+==Lists==
+: The Yioop Wiki Syntax supported of ways of listing items:
+bulleted/unordered list, numbered/ordered lists, and
+definition lists. Below are some examples:
+
+===Unordered Lists===
+<nowiki>
+* Item1
+** SubItem1
+** SubItem2
+*** SubSubItem1
+* Item 2
+* Item 3
+</nowiki>
+would be drawn as:
+* Item1
+** SubItem1
+** SubItem2
+*** SubSubItem1
+* Item 2
+* Item 3
+
+===Ordered Lists===
+<nowiki>
+# Item1
+## SubItem1
+## SubItem2
+### SubSubItem1
+# Item 2
+# Item 3
+</nowiki>
+# Item1
+## SubItem1
+## SubItem2
+### SubSubItem1
+# Item 2
+# Item 3
+
+===Mixed Lists===
+<nowiki>
+# Item1
+#* SubItem1
+#* SubItem2
+#*# SubSubItem1
+# Item 2
+# Item 3
+</nowiki>
+# Item1
+#* SubItem1
+#* SubItem2
+#*# SubSubItem1
+# Item 2
+# Item 3
+
+===Definition Lists===
+<nowiki>
+;Term 1: Definition of Term 1
+;Term 2: Definition of Term 2
+</nowiki>
+;Term 1: Definition of Term 1
+;Term 2: Definition of Term 2
+
+==Tables==
+: A table begins with {`|`  and ends with `|`}. Cells are separated with | and
+rows are separated with |- as can be seen in the following
+example:
+<nowiki>
+{|
+|a||b
+|-
+|c||d
+|}
+</nowiki>
+{|
+|a||b
+|-
+|c||d
+|}
+Headings for columns and rows can be made by using an exclamation point, !,
+rather than a vertical bar |. For example,
+<nowiki>
+{|
+!a!!b
+|-
+|c||d
+|}
+</nowiki>
+{|
+!a!!b
+|-
+|c||d
+|}
+Captions can be added using the + symbol:
+<nowiki>
+{|
+|+ My Caption
+!a!!b
+|-
+|c||d
+|}
+</nowiki>
+{|
+|+ My Caption
+!a!!b
+|-
+|c||d
+|}
+Finally, you can put a CSS class or style attributes (or both) on the first line
+of the table to further control how it looks:
+<nowiki>
+{| class="wikitable"
+|+ My Caption
+!a!!b
+|-
+|c||d
+|}
+</nowiki>
+{| class="wikitable"
+|+ My Caption
+!a!!b
+|-
+|c||d
+|}
+Within a cell attributes like align, valign, styles, and class can be used. For
+example,
+<nowiki>
+{|
+| style="text-align:right;"| a| b
+|-
+| lalala | lalala
+|}
+</nowiki>
+{|
+| style="text-align:right;"| a| b
+|-
+| lalala | lalala
+|}
+
+==Math==
+
+: Math can be included into a wiki document by either using the math tag:
+<nowiki>
+<math>
+\sum_{i=1}^{n} i = frac{(n+1)(n)}{2}
+</math>
+</nowiki>
+
+<math>
+\sum_{i=1}^{n} i = frac{(n+1)(n)}{2}
+</math>
+
+or by enclosing the math in backticks:
+
+<pre>
+`[[1, -2],[3,4]]`
+</pre>
+
+`[[1, -2],[3,4]]`.
+
+Rendering of math is done using [[https://www.mathjax.org/|MathJax]], making us of the [[https://en.wikipedia.org/wiki/ASCIIMathML|ASCIImathml]] extensions.
+
+==Links and Relationships==
+: A hypertext link to another document can be inserted into a wiki page using
+the chain link icon in the GUI. Alternatively, there are several techniques
+for inserting a link into a page depending on whether the link is to a page
+within the same wiki group, is a link to a page on a different wiki
+group, or is a link to a different website. In addition to normal
+hypertext links, Yioop also supports relationship links.
+
+'''Intra-Group Wiki Links''' use the syntax:
+<nowiki>
+[[name_of_wiki_page]]
+or
+[[name_of_wiki_page|text for the link]]
+or
+[[name_of_wiki_page#heading_or_id_on_page|text for the link]]
+</nowiki>
+for example, to make a link to this Syntax page one could write,
+<nowiki>
+[[Syntax|Yioop Wiki Syntax Page]]
+</nowiki>
+which would look like,
+
+[[Syntax|Yioop Wiki Syntax Page]]
+
+'''Inter-Group Wiki Links''' use the syntax:
+<nowiki>
+[[name_of-group@name_of_wiki_page|text for the link]]
+</nowiki>
+
+'''Different Website Links''' use the syntax:
+<nowiki>
+[[website_url|text for the link]]
+</nowiki>
+
+: Relationships are a generalized form of link. They are used to express
+a more complicated linking between two wiki pages and have the syntax:
+
+<nowiki>
+[[relationship_type|wiki_page_name|text for the link]]
+</nowiki>
+
+: In the navigation dropdown for a Yioop wiki page there are items for
+what links to the current page and what relates to the current page
+based on the links and relationships a page belongs to.
+
+==Recent Places Dropdowns==
+: You can add a dropdown that can allow users to navigate to recently visited
+wiki pages using the syntax:
+
+<sub>`[`{recent_places}]</sub>
+
+This looks like:
+
+[{recent_places}]
+
+==Adding Resources to a Page==
+
+: Yioop wiki syntax supports adding search bars, audio, images, and video to a
+page. The magnifying class edit tool icon can be used to add a search bar via
+the GUI. This can also be added by hand with the syntax:
+<nowiki>
+{{search:default|size:small|placeholder:Search Placeholder Text}}
+</nowiki>
+This syntax is split into three parts each separated by a vertical bar |. The
+first part search:default means results from searches should come from the
+default search index. You can replace default with the timestamp of a specific
+index or mix if you do not want to use the default. The second group size:small
+indicates the size of the search bar to be drawn. Choices of size are small,
+medium, and large. Finally, placeholder:Search Placeholder Text indicates the
+grayed out background text in the search input before typing is done should
+read: Search Placeholder Text. Here is what the above code outputs:
+
+{{search:default|size:small|placeholder:Search Placeholder Text}}
+
+: Image, video and other media resources can be associated with a page by dragging
+and dropping them in the edit textarea or by clicking on the link click to select
+link in the gray box below the textarea. This would add wiki code such as
+
+<sub>((resource`:`myphoto.jpg|Resource Description))</sub>
+
+to the page. Only saving the page will save this code and upload the resource to
+the server. In the above ''myphoto.jpg'' is the resource that will be inserted and
+Resource Description is the alternative text to use in case the viewing browser
+cannot display jpg files. To add a resource
+from a different wiki page belonging to the same group to the current wiki
+page one can use a syntax like:
+
+<sub>((resource`:`Documentation:ConfigureScreenForm1.png|The work directory form))</sub>
+
+Here Documentation would be the page and ConfigureScreenForm1.png the resource.
+You can also insert resources from a data-string using ''resource-data'' rather than
+''resource''. For example:
+
+<sub>((resource-data`:`image/jpeg;base64,/9j/4AAQSkZJRg...rest of image data...|Seekquarry Logo))</sub>
+

+
+be aware though that the default maximum wiki page size is 512Kb (this can be set in src/configs/Config.php).
+
+: Sometimes it is useful to edit the basic resource link
+above to make a link which is a thumbnail of the resource which points to a
+separate page containing that resource. This can be done using the syntax:
+
+<sub>((resource-thumb`:`myphoto.jpg|Resource Description))</sub>
+
+: Similarly, by default for resources like PDFs, epub's, etc., the resource tag inlines
+the whole resource into the page, if instead one wants a clickable link to a page where
+the resource is displayed one can use the syntax:
+
+<sub>((resource-link`:`my_document.pdf|Resource Description))</sub>
+
+: Comma separated value files (.csv or CSV files) are inlined into a page as a table. Which rows and columns of the CSV to present in this table can be controlled by the resource line. The general format for including
+a CSV resource is:
+
+<sub> ((resource`:`resource_name.csv#config#top_left_cell#bottom_right_cell|Resource Description))</sub>
+
+For example,
+
+<sub>((resource`:`resource_name.csv##B2#C3|Resource Description))</sub>
+
+might output
+
+((resource-data:text/csv;base64,LCwsLAosLTIsMywsCiw1LDQsLAosLCwsCiwsLCwK##B2#C3|Example CSV with Headings))
+
+I.e., just the portion of the CSV given by the rectangle between the cells B2 and C3. Using a config directive we can omit the spreadsheet row and column headings as follows:
+
+<sub>((resource`:`resource_name.csv#noheadings#B2#C3|Resource Description)) </sub>
+
+which might output
+
+
+((resource-data:text/csv;base64,LCwsLAosLTIsMywsCiw1LDQsLAosLCwsCiwsLCwK#noheadings#B2#C3|Example CSV without Headings))
+
+CSV spreadsheet files can also be used to output a variety of charts. The general format for the command to insert a chart resource is:
+
+<sub>((resource-chart_type`:`resource_name.csv#char_config#x_start#x_end#y_start#y_end|Resource Description))</sub>
+
+Here ''chart_type'' can be one of ''bargraph'',  ''linegraph'', or ''pointgraph''. For example, one might have a line like:
+
+<sub>((resource-bargraph`:`resource_name.csv##B1#B4#C1#C4|Quadratic Function)) </sub>
+
+which could produce a chart like
+
+((resource-bargraph:##(1,1)#(2,4)#(3,9)#(4,16)|Quadratic Function))
+
+In the above example, the values for the `x` coordinates would come from the cells B1, B2, B3, B4 from
+''resource_name.csv '' and the values for the `y` coordinates would come from cells C1, C2, C3, C4 from
+''resource_name.csv ''. Alternatively, rather than use a CSV to get out data we can just list the points we want to plot with a command like:
+
+<sub>((resource-bargraph`:`##(1,1)#(2,4)#(3,9)#(4,16)|Quadratic Function))</sub>
+
+==Manipulating Page Resources==
+
+: A list of media that have already been associated with
+a page appears under the Page Resource heading below the textarea. This
+table allows the user to rename and delete resources as well as insert the
+same resource at multiple locations within the same document.
+
+: The resources section of the edit page can be thought of as similar to
+a folder in Windows or MacOS. One can have subfolders of the resource folder.
+
+: The '''Places''' dropdown at the top of the '''Page Resource''' section allows one to navigate
+these folders.
+
+: The '''Filter''' textfield lets you enter a search string.
+Clicking '''Go''' then shows only those resources
+which contain that search string in their title.
+
+: The '''Clip Folder''' dropdown is used to copy files between folders and pages.
+Its current value is the folder that the '''Clip Copy''' buttons next to resources
+will copy their resource to when clicked. You can set the '''Clip Folder''' to
+the current folder using the dropdown, then  move to the page and folder that
+you would like to copy stuff from and click the '''Clip Copy''' button of the
+desired resource.
+
+: The '''Name''', '''Size''', '''Modified''' header links above the resources list
+control the sort order for the resource list. If a page is a media list page,
+then even in read mode, the sort order selected is remembered when drawing the
+media list.
+
+: The '''Actions''' drop can be used to create new folders, new text files, and new csv
+text files within the current page resource folder. These are initial named beginning
+with ''untitled'' followed by some number, and if applicable a file extension.
+
+: Resources entries for the resources list consist first of an icon, followed by a textfield
+with a name for the resource, followed by buttons for actions that can be done to that resource
+(Rename, Add to Page, Clip Copy), followed by a link [X], which can be used to delete the resource.
+If a resource is editable the icon will look like a plus sign together with a pencil. Clicking
+on the icon will then let you edit the resource.
+
+===Text and CSV Resources===
+: For normal text files clicking edit will bring up a textarea with the context of the text to edit.
+For CSV (comma separated value) files this will present the file as an editable spreadsheet.
+Yioop spreadsheets can have equation much like Excel spreadsheets. Clicking on a cell lets one
+edit its contents. For example, if in the cell A3
+one entered the equation:
+ = A1+A2
+then clicking out of the cell would cause it to refresh with the value of the sum of the contents of
+cells A1 and A2. In addition, to the standard arithmetic operators ['*', '/', '+', '-', '%'], the
+spreadsheet expressions can use float or integer literals, and can make use of the following table
+of built-in functions:
+
+{| class="wikitable"
+!Function Name!!Description
+|-
+!avg(x1,...,xn), avg(x1:xn)|| computes average of values of cells listed as arguments
+|-
+!ceil(x)|| rounds the value of x up to nearest integer
+|-
+!cell(i,j)|| returns the contents of the cell with column name of letter j, and row name i. For example, cell(2,'B') would return the contents of cell B2.
+|-
+!col(value, search_row, start_col, end_col)|| searches the row ''search_row'' between the columns
+''start_col'', ''end_col'' for ''value''. Returns the column name where this value was found or -1 if not found.
+For example, col(3, 2, "B", "D") might return C if the cell C2 had value 3.
+|-
+!exp(x)|| computes `e^x`
+|-
+!floor(x)|| rounds the value of x down to the nearest integer
+|-
+!log(x)|| computes `log x`
+|-
+!min(x1,...,xn), min(x1:xn)|| computes minimum value of cells listed as arguments
+|-
+!max(x1,...,xn), max(x1:xn)|| computes maximum value of cells listed as arguments
+|-
+!pow(x,y)|| computes `x^y`
+|-
+!row(value, search_col, start_row, end_row)|| searches the column ''search_col''
+between the rows ''start_row'', ''end_row'' for ''value''.
+Returns the row name where this value was found or -1 if not found.
+For example, row(3, "C", "1", "5") might return 2 if the cell C2 had value 3.
+|-
+!sqrt(x)|| computes `sqrt(x)`
+|-
+!sum(x1,...,xn), sum(x1:xn)|| computes sum of values of cells listed as arguments
+|-
+!username()|| returns username of the person using this CSV file
+|}
+
+===HTML, PDF and EPub Resources===
+: How HTML, PDF, EPub resources included on a page render depends on how the Yioop wiki software
+has been configured. If no special configuration has been done, then HTML and PDF documents
+will bbe rendered in an <iframe> tag within the current wiki page. In the EPub, case a link
+to download the resource will be given. If the wiki software detects the presence of the
+file APP_DIR/scripts/pdf.js ([[https://en.wikipedia.org/wiki/PDF.js|PDF.js]])
+or APP_DIR/scripts/epub.js ([[https://github.com/futurepress/epub.js|epub.js]]), the wiki
+system will render the resource in a Javascript viewer and will do things like remember reading
+position.
+
+
+===Video and Audio Resources===
+
+: Not all browsers support the same video and audio formats for playback. For this reason
+it sometimes is useful to have multiple video resources for the same video. For example,
+you might have a .ogv and .vp8 version of the same video recording. In read (non-edit)
+mode, the Yioop wiki system displays only one link for video or audio files that have
+the same name except for extension. It then includes the grouped file as separated <source>
+tags within either the <video> or <audio> html tag used to render the item in the browser.
+In this way, you can make your media take best advantages to whatever capabilities your
+client's browser has. If you don't feel like recoding your media in such a fancy way, a safe
+rule of thumb is that .mp3 audio will playback in all modern browser, and that .mp4 video
+will playback in all modern browser.
+
+: For video it is sometimes useful to add a subtitle or caption track. Yioop wiki supports
+[[https://en.wikipedia.org/wiki/WebVTT|WebVTT]] format subtitles and captions. To see how
+Yioop wiki makes use of these files, suppose you included a resource ''foo.mp4'' in your
+wiki pages, and you also had a file named ''foo-captions-en-US.vtt'' then when the HTML
+page is generated from your wiki page, a <track> tag for the caption file would be added
+to the <video> tag. A user seeing this page would then see in the video player a closed caption
+symbol and be able to turn on/off (defaults off) the English captions. If you wanted
+named the file ''foo-subtitles-en-US.vtt'' instead, then Yioop wiki would include it as a
+subtitles track (defaults on). You can add captions/subtitle files for as many languages as
+desired.
+
+: When viewing the page resources for a page in edit mode, one can see one file/resource and
+no grouping of resources by name is done. In this way you can keep track of exactly what
+resources are available for a page.
+
+==Page Settings, Page Type==
+
+: In edit mode for a wiki page, next to the page name, is a link [Settings].
+Clicking this link expands a form which can be used to control global settings
+for a wiki page.  This form contains a drop down for the page type, another
+drop down for the type of border for the page in non-logged in mode,
+a checkbox for whether a table of contents should be auto-generated from level 2
+and level three headings and then text
+fields or areas for the page title, author, meta robots, and page description.
+Beneath this one can specify another wiki page to be used as a header for this
+page and also specify another wiki page to be used as a footer for this page.
+
+: The contents of the page title is displayed in the browser title when the
+wiki page is accessed with the  Activity Panel collapsed or when not logged in.
+Similarly, in the collapsed or not logged in mode, if one looks as the HTML
+page source for the page,  in the head of document, <meta> tags for author,
+robots, and description are set according to these fields. These fields can
+be useful for search engine optimization. The robots meta tag can be
+used to control how search engine robots index the page. Wikipedia has more information on
+[[https://en.wikipedia.org/wiki/Meta_element|Meta Elements]].
+
+: The '''Standard''' page type treats the page as a usual wiki page.
+
+: '''Page Alias''' type redirects the current page to another page name. This can
+be used to handle things like different names for the same topic or to do localization
+of pages. For example, if you switch the locale from English to French and
+you were on the wiki page dental_floss when you switch to French the article
+dental_floss might redirect to the page dentrifice.
+
+: '''Media List''' type means that the page, when read, should display just the
+resources in the page as a list of thumbnails and links. These links for the
+resources go to a separate pages used to display these resources.
+This kind of page is useful for a gallery of
+images or a collection of audio or video files.
+
+: '''Presentation''' type is for a wiki page whose purpose is a slide presentation. In this mode,
+....
+on a line by itself is used to separate one slide. If presentation type is a selected a new
+slide icon appears in the wiki edit bar allowining one to easily add new slides.
+When the Activity panel is not collapsed and you are reading a presentation, it just
+displays as a single page with all slides visible. Collapsing the Activity panel presents
+the slides as a typical slide presentation using the
 [[www.w3.org/Talks/Tools/Slidy2/Overview.html|Slidy]] javascript.
