It extends the standard Markdown in a few significant ways to add some useful functionality. - -You can use GFM in - -- commit messages -- comments -- issues -- merge requests -- milestones -- wiki pages - -You can also use other rich text files in GitLab. You might have to install a dependency to do so. Please see the [github-markup gem readme](https://github.com/gitlabhq/markup#markups) for more information. - -## Newlines - -GFM honors the markdown specification in how [paragraphs and line breaks are handled](http://daringfireball.net/projects/markdown/syntax#p). - -A paragraph is simply one or more consecutive lines of text, separated by one or more blank lines. -Line-breaks, or softreturns, are rendered if you end a line with two or more spaces - - Roses are red [followed by two or more spaces] - Violets are blue - - Sugar is sweet - -Roses are red -Violets are blue - -Sugar is sweet - -## Multiple underscores in words - -It is not reasonable to italicize just _part_ of a word, especially when you're dealing with code and names that often appear with multiple underscores. Therefore, GFM ignores multiple underscores in words. - - perform_complicated_task - do_this_and_do_that_and_another_thing - -perform_complicated_task -do_this_and_do_that_and_another_thing - -## URL auto-linking - -GFM will autolink standard URLs you copy and paste into your text. So if you want to link to a URL (instead of a textural link), you can simply put the URL in verbatim and it will be turned into a link to that URL. - - http://www.google.com - -http://www.google.com - -## Code and Syntax Highlighting - -Blocks of code are either fenced by lines with three back-ticks <code>```</code>, or are indented with four spaces. Only the fenced code blocks support syntax highlighting. - -```no-highlight -Inline `code` has `back-ticks around` it. -``` - -Inline `code` has `back-ticks around` it. - -Example: - - ```javascript - var s = "JavaScript syntax highlighting"; - alert(s); - ``` - - ```python - def function(): - #indenting works just fine in the fenced code block - s = "Python syntax highlighting" - print s - ``` - - ```ruby - require 'redcarpet' - markdown = Redcarpet.new("Hello World!") - puts markdown.to_html - ``` - - ``` - No language indicated, so no syntax highlighting. - s = "There is no highlighting for this." - But let's throw in a <b>tag</b>. - ``` - -becomes: - -```javascript -var s = "JavaScript syntax highlighting"; -alert(s); -``` - -```python -def function(): - #indenting works just fine in the fenced code block - s = "Python syntax highlighting" - print s -``` - -```ruby -require 'redcarpet' -markdown = Redcarpet.new("Hello World!") -puts markdown.to_html -``` - -``` -No language indicated, so no syntax highlighting. -s = "There is no highlighting for this." -But let's throw in a <b>tag</b>. -``` - -## Emoji - - Sometimes you want to :monkey: around a bit and add some :star2: to your :speech_balloon:.

To create a task, add an unordered list to the description in an issue or merge request, formatted like so: - -```no-highlight -* [x] Completed task -* [ ] Unfinished task - * [x] Nested task -``` - -Task lists can only be created in descriptions, not in titles or comments. Task item state can be managed by editing the description's Markdown or by clicking the rendered checkboxes. - -# Standard Markdown - -## Headers - -```no-highlight -# H1 -## H2 -### H3 -#### H4 -##### H5 -###### H6 - -Alternatively, for H1 and H2, an underline-ish style: - -Alt-H1 -====== - -Alt-H2 ------- -``` - -# H1 -## H2 -### H3 -#### H4 -##### H5 -###### H6 - -Alternatively, for H1 and H2, an underline-ish style: - -Alt-H1 -====== - -Alt-H2 ------- - -### Header IDs and links - -All markdown rendered headers automatically get IDs, except for comments. - -On hover a link to those IDs becomes visible to make it easier to copy the link to the header to give it to someone else. - -The IDs are generated from the content of the header according to the following rules: - -1. remove the heading hashes `#` and process the rest of the line as it would be processed if it were not a header -2. from the result, remove all HTML tags, but keep their inner content -3. convert all characters to lowercase -4. convert all characters except `[a-z0-9_-]` into hyphens `-` -5. transform multiple adjacent hyphens into a single hyphen -6. remove trailing and heading hyphens - -For example: - -``` -###### ..Ab_c-d. e [anchor](URL) .. -``` - -which renders as: - -###### ..Ab_c-d. e [anchor](URL) .. - -will first be converted by step 1) into a string like: - -``` -..Ab_c-d. e <a href="URL">anchor</a> <img src="URL" alt="alt text"/>.. -``` - -After removing the tags in step 2) we get: - -``` -..Ab_c-d. e anchor .. -``` - -And applying all the other steps gives the id: - -``` -ab_c-d-e-anchor -``` - -Note in particular how: - -- for markdown anchors `[text](URL)`, only the `text` is used -- markdown images `` are completely ignored - -## Emphasis - -```no-highlight -Emphasis, aka italics, with *asterisks* or _underscores_. - -Strong emphasis, aka bold, with **asterisks** or __underscores__. - -Combined emphasis with **asterisks and _underscores_**. - -Strikethrough uses two tildes. ~~Scratch this.~~ -``` - -Emphasis, aka italics, with *asterisks* or _underscores_. - -Strong emphasis, aka bold, with **asterisks** or __underscores__. - -Combined emphasis with **asterisks and _underscores_**. - -Strikethrough uses two tildes. ~~Scratch this.~~ - -## Lists - -```no-highlight -1.

The reason for this is that, in GitLab, wiki is always a separate git repository. For example: - -`[I'm a reference-style link][style]` - -will point the link to `wikis/style` when the link is inside of a wiki markdown file. - -## Images - - Here's our logo (hover to see the title text): - - Inline-style: -  - - Reference-style: - ![alt text1][logo] - - [logo]: assets/logo-white.png - -Here's our logo: - -Inline-style: - - - -Reference-style: - -![alt text][logo] - -[logo]: /assets/logo-white.png - -## Blockquotes - -```no-highlight -> Blockquotes are very handy in email to emulate reply text. -> This line is part of the same quote. - -Quote break. - -> This is a very long line that will still be quoted properly when it wraps.

Oh, you can *put* **Markdown** into a blockquote. - -## Inline HTML - -You can also use raw HTML in your Markdown, and it'll mostly work pretty well. - -See the documentation for HTML::Pipeline's [SanitizationFilter](http://www.rubydoc.info/gems/html-pipeline/HTML/Pipeline/SanitizationFilter#WHITELIST-constant) class for the list of allowed HTML tags and attributes. In addition to the default `SanitizationFilter` whitelist, GitLab allows the `class`, `id`, and `style` attributes. - -```no-highlight -<dl> - <dt>Definition list</dt> - <dd>Is something people use sometimes.</dd> - - <dt>Markdown in HTML</dt> - <dd>Does *not* work **very** well.
