* Refactor markup render system (#32612)wxiaoguang2024-11-241-2/+2
| | | | | | | | | | This PR removes (almost) all path tricks, and introduces "renderhelper" package. Now we can clearly see the rendering behaviors for comment/file/wiki, more details are in "renderhelper" tests. Fix #31411 , fix #18592, fix #25632 and maybe more problems. (ps: fix #32608 by the way)

* Rework markup link rendering (#26745)KN4CK3R2024-01-151-1/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes #26548 This PR refactors the rendering of markup links. The old code uses `strings.Replace` to change some urls while the new code uses more context to decide which link should be generated. The added tests should ensure the same output for the old and new behaviour (besides the bug). We may need to refactor the rendering a bit more to make it clear how the different helper methods render the input string. There are lots of options (resolve links / images / mentions / git hashes / emojis / ...) but you don't really know what helper uses which options. For example, we currently support images in the user description which should not be allowed I think: <details> <summary>Profile</summary> https://try.gitea.io/KN4CK3R ![grafik](https://github.com/go-gitea/gitea/assets/1666336/109ae422-496d-4200-b52e-b3a528f553e5) </details> --------- Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
* Add RTL rendering support to Markdown (#24816)silverwind2023-05-201-2/+4
| | | | | | | | | | | | | | | | | | | | Support RTL content in Markdown: ![image](https://github.com/go-gitea/gitea/assets/115237/dedb1b0c-2f05-40dc-931a-0d9dc81f7c97) Example document: https://try.gitea.io/silverwind/symlink-test/src/branch/master/bidi-text.md Same on GitHub: https://github.com/silverwind/symlink-test/blob/master/bidi-text.md `dir=auto` enables a browser heuristic that sets the text direction automatically. It is the only way to get automatic text direction. Ref: https://codeberg.org/Codeberg/Community/issues/1021 --------- Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
* Improve Wiki TOC (#24137)wxiaoguang2023-04-171-1/+12
| | | | | | | | | | The old code has a lot of technical debts, eg: `repo/wiki/view.tmpl` / `Iterate` This PR improves the Wiki TOC display and improves the code. --------- Co-authored-by: delvh <dev.lh@web.de>
* Editor preview support for external renderers (#23333)Brecht Van Lommel2023-03-241-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | Remove `[repository.editor] PREVIEWABLE_FILE_MODES` setting that seemed like it was intended to support this but did not work. Instead, whenever viewing a file shows a preview, also have a Preview tab in the file editor. Add new `/markup` web and API endpoints with `comment`, `gfm`, `markdown` and new `file` mode that uses a file path to determine the renderer. Remove `/markdown` web endpoint but keep the API for backwards and GitHub compatibility. ## ⚠️ BREAKING ⚠️ The `[repository.editor] PREVIEWABLE_FILE_MODES` setting was removed. This setting served no practical purpose and was not working correctly. Instead a preview tab is always shown in the file editor when supported. --------- Co-authored-by: zeripath <art27@cantab.net> Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com>
* Move `IsReadmeFile*` from `modules/markup/` to `modules/util` (#22877)Nick2023-02-131-38/+0
| | | | | | | | | These functions don't examine contents, just filenames, so they don't fit in well in a markup module. This was originally part of https://github.com/go-gitea/gitea/pull/22177. Signed-off-by: Nick Guenther <nick.guenther@polymtl.ca>

| | | | | | | | | | | Previously mentioning a user would link to its profile, regardless of whether the user existed.

* Prevent double sanitize (#16386)KN4CK3R2021-11-191-2/+1
| | | | | | | | * Prevent double sanitize. * Use SanitizeReaderToWriter. At the moment `actualRender` uses `SanitizeReader` to sanitize the output. But `SanitizeReader` gets called in `markup.render` too so the output gets sanitized twice. I moved the `SanitizeReader` call into `RenderRaw` because this method does not use `markup.render`. I would like to remove the `RenderRaw`/`RenderRawString` methods too because they are only called from tests, the fuzzer and the `/markup/raw` api endpoint. This endpoint is not in use so I think we could remove them. If we really in the future need a method to render markdown without PostProcessing we could achieve this with a more flexible `renderer.NeedPostProcess` method.

* More efficiently parse shas for shaPostProcessor (#16101)zeripath2021-06-211-7/+39
| | | | | | | | | | | | | | | | * More efficiently parse shas for shaPostProcessor The shaPostProcessor currently repeatedly calls git rev-parse --verify on both backends which is fine if there is only one thing that matches a sha - however if there are multiple things then this becomes wildly inefficient. This PR provides functions for both backends which are much faster to use.
