* Add .livemd as a markdown extension (#22730)contra-bit2023-04-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ## Needs and benefits [Livebook](https://livebook.dev/) notebooks are used for code documentation and for deep dives and note-taking in the elixir ecosystem. Rendering these in these as Markdown on frogejo has many benefits, since livemd is a subset of markdown. Some of the benefits are: - New users of elixir and livebook are scared by unformated .livemd files, but are shown what they expect - Sharing a notebook is as easy as sharing a link, no need to install the software in order to see the results. [goldmark-meraid ](https://github.com/abhinav/goldmark-mermaid) is a mermaid-js parser already included in gitea. This makes the .livemd rendering integration feature complete. With this PR class diagrams, ER Diagrams, flow charts and much more will be rendered perfectly. With the additional functionality gitea will be an ideal tool for sharing resources with fellow software engineers working in the elixir ecosystem. Allowing the git forge to be used without needing to install any software. ## Feature Description This issue requests the .livemd extension to be added as a Markdown language extension. - `.livemd` is the extension of Livebook which is an Elixir version of Jupyter Notebook. - `.livemd` is` a subset of Markdown. This would require the .livemd to be recognized as a markdown file. The Goldmark the markdown parser should handle the parsing and rendering automatically. Here is the corresponding commit for GitHub linguist: https://github.com/github/linguist/pull/5672 Here is a sample page of a livemd file: https://github.com/github/linguist/blob/master/samples/Markdown/livebook.livemd ## Screenshots The first screenshot shows how github shows the sample .livemd in the browser. The second screenshot shows how mermaid js, renders my development notebook and its corresponding ER Diagram. The source code can be found here: https://codeberg.org/lgh/Termi/src/commit/79615f74281789a1f2967b57bad0c67c356cef1f/termiNotes.livemd ## Testing I just changed the file extension from `.livemd`to `.md`and the document already renders perfectly on codeberg.

* Refactor config provider (#24245)Lunny Xiao2023-04-251-5/+3

* Refactor the setting to make unit test easier (#22405)Lunny Xiao2023-02-201-3/+19
| | | | | | | | | | | | | | | | | | | | | | Some bugs caused by less unit tests in fundamental packages. This PR refactor `setting` package so that create a unit test will be easier than before. - All `LoadFromXXX` files has been splited as two functions, one is `InitProviderFromXXX` and `LoadCommonSettings`. The first functions will only include the code to create or new a ini file. The second function will load common settings. - It also renames all functions in setting from `newXXXService` to `loadXXXSetting` or `loadXXXFrom` to make the function name less confusing. - Move `XORMLog` to `SQLLog` because it's a better name for that. Maybe we should finally move these `loadXXXSetting` into the `XXXInit` function? Any idea? --------- Co-authored-by: 6543 <6543@obermui.de> Co-authored-by: delvh <dev.lh@web.de>

* Fix sanitizer config - multiple rules (#11133)Alexander Scheel2020-04-291-33/+25
| | | | | | | | | | | | | | | | | | | | | | | | In #9888, it was reported that my earlier pull request #9075 didn't quite function as expected. I was quite hopeful the `ValuesWithShadow()` worked as expected (and, I thought my testing showed it did) but I guess not. @zeripath proposed an alternative syntax which I like: ```ini [markup.sanitizer.1] ELEMENT=a ALLOW_ATTR=target REGEXP=something [markup.sanitizer.2] ELEMENT=a ALLOW_ATTR=target REGEXP=something ``` This was quite easy to adopt into the existing code. I've done so in a semi-backwards-compatible manner: - The value from `.Value()` is used for each element. - We parse `[markup.sanitizer]` and all `[markup.sanitizer.*]` sections and add them as rules. This means that existing configs will load one rule (not all rules). It also means people can use string identifiers (`[markup.sanitiser.KaTeX]`) if they prefer, instead of numbered ones.

* Markdown: Sanitizier Configuration (#9075)Alexander Scheel2019-12-071-22/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Support custom sanitization policy Allowing the gitea administrator to configure sanitization policy allows them to couple external renders and custom templates to support more markup. In particular, the `pandoc` renderer allows generating KaTeX annotations, wrapping them in `<span>` elements with class `math` and either `inline` or `display` (depending on whether or not inline or block mode was requested). This iteration gives the administrator whitelisting powers; carefully crafted regexes will thus let through only the desired attributes necessary to support their custom markup. Resolves: #9054 Signed-off-by: Alexander Scheel <alexander.m.scheel@gmail.com> * Document new sanitization configuration - Adds basic documentation to app.ini.sample, - Adds an example to the Configuration Cheat Sheet, and - Adds extended information to External Renderers section.

Signed-off-by: Alexander Scheel <alexander.m.scheel@gmail.com> * Fix plural ELEMENT and ALLOW_ATTR in docs These were left over from their initial names.
