* Upgrade chroma to v2.3.0 (#21259)silverwind2022-09-261-22/+17
| | | | | | | | | | | | | The behaviour of `PreventSurroundingPre` has changed in https://github.com/alecthomas/chroma/pull/618 so that apparently it now causes line wrapper tags to be no longer emitted, but we need some form of indication to split the HTML into lines, so I did what https://github.com/yuin/goldmark-highlighting/pull/33 did and added the `nopWrapper`. Maybe there are more elegant solutions but for some reason, just splitting the HTML string on `\n` did not work. Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
* Rework file highlight rendering and fix yaml copy-paste (#19967)silverwind2022-07-302-130/+164
| | | | | | | | | | | * Rework file highlight rendering and fix yaml copy-paste * use Split+Trim to replace tag parser * remove unnecessary bytes.Count * remove newLineInHTML = "&#10;" Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
* Improve code diff highlight, fix incorrect rendered diff result (#19958)wxiaoguang2022-07-231-3/+5
| | | Use Unicode placeholders to replace HTML tags and HTML entities first, then do diff, then recover the HTML tags and HTML entities. Now the code diff with highlight has stable behavior, and won't emit broken tags.
* Add more linters to improve code readability (#19989)Wim2022-06-201-4/+4
| | | | | | | | | | Add nakedret, unconvert, wastedassign, stylecheck and nolintlint linters to improve code readability - nakedret - https://github.com/alexkohler/nakedret - nakedret is a Go static analysis tool to find naked returns in functions greater than a specified function length. - unconvert - https://github.com/mdempsky/unconvert - Remove unnecessary type conversions - wastedassign - https://github.com/sanposhiho/wastedassign - wastedassign finds wasted assignment statements. - notlintlint - Reports ill-formed or insufficient nolint directives - stylecheck - https://staticcheck.io/docs/checks/#ST - keep style consistent - excluded: [ST1003 - Poorly chosen identifier](https://staticcheck.io/docs/checks/#ST1003) and [ST1005 - Incorrectly formatted error string](https://staticcheck.io/docs/checks/#ST1005)
* Fix copy/paste of empty lines (#19798)silverwind2022-06-102-61/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | * Fix copy/paste of empty newlines again Fixes: https://github.com/go-gitea/gitea/issues/19331 Regressed by: https://github.com/go-gitea/gitea/pull/18270 Needed to do another newline addition to the Chroma output HTML to get copy/paste work again. The previous replacement conditions are probably obsolete, but as I'm not 100% sure, I opted to keep them. Specifically, the Chroma HTML change mentioned in https://github.com/go-gitea/gitea/pull/18270#issuecomment-1013350246 broke our previous newline replacement for such empty lines. Also included are a few changes to make the test more pleasant to work with. * run go mod tidy * add util.Dedent * copy in the code Co-authored-by: techknowlogick <techknowlogick@gitea.io> Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com> Co-authored-by: Lauris BH <lauris@nix.lv>

* Add .gitattribute assisted language detection to blame, diff and render (#17590)zeripath2021-11-172-8/+30
| | | | | | | Use check attribute code to check the assigned language of a file and send that in to chroma as a hint for the language of the file. Signed-off-by: Andrew Thornton <art27@cantab.net>

* Prevent panic in Org mode HighlightCodeBlock (#17140)zeripath2021-09-241-11/+12
| | | | | | | | | | | When rendering source in org mode there is a mistake in the highlight code that causes a panic. This PR fixes this. Fix #17139 Signed-off-by: Andrew Thornton <art27@cantab.net>
* Just use a slice when rendering file (#16774)zeripath2021-08-232-41/+39
| | | | | | Highlight currently uses a map which is memory inefficient. Switch to use a slice instead. Signed-off-by: Andrew Thornton <art27@cantab.net>
* Ensure empty lines are copiable and final new line too (#16678)zeripath2021-08-142-0/+116
| | | | | | | | | | | | * Ensure empty lines are copiable and final new line too When files are highlighted the newline character needs to be added in a whitespace compliant mode. Also ensure the final empty newline is rendered. Fix #16434 * Add test and ensure spans closed Signed-off-by: Andrew Thornton <art27@cantab.net>

| | | | | | | | | | | | | * Use existing analyzer module for language detction for highlighting Thanks @lafriks for pointing out we can reuse existing code for more reliable language detection here. * Update modules/highlight/highlight.go Co-authored-by: Lauris BH <lauris@nix.lv> Co-authored-by: zeripath <art27@cantab.net> Co-authored-by: Lauris BH <lauris@nix.lv> Co-authored-by: techknowlogick <techknowlogick@gitea.io>

* Ensure syntax highlighting is the same inside diffs (#12205)mrsdizzie2020-07-111-4/+8
| | | | | Make sure to end up with the same syntax highlighting inside various sections of diffs by processing the code first before detecting specific changes between the lines. Also try and make sure that when highlighting individual lines in a diff that it is tokenized the same as it would be when part of an entire file with more context. Fixes: #12190
* Make copy/paste work for source code (#12191)mrsdizzie2020-07-081-2/+15
| | | | | | | | | | | | | | | * Make copy/paste work for source code Fix regression casued by #12047 so copy/paste works properly in all browsers. Fixes #12184 Also while looking at this I saw a small display issue for blame view. I think #12023 was merged into original PR through an update branch before #12047 was merged and made one of the css ruules not apply anymore. * use pseudo-element to prevent copying of comment + symbol even when not visually selected * remove added newline here should not be necessary anymore * make sure empty line is newline so there is something to select and copy
* Remove newline when highlighting random chunks of code (#12180)mrsdizzie2020-07-081-1/+2
| | | | | | | | | | | * Remove newline when highlighting random chunks of code Somewhere when tokenizing a newline gets added to code formatted by chroma. This breaks the case of 'added-code' inside of an 'added-line' in a diff. Just remove any newline when processing chunks of code since we don't need it. Fixes #12172 * don't process empty lines * This is the proper way to fix this by telling chroma not to add the newline in the first place
* Server-side syntax highlighting for all code (#12047)mrsdizzie2020-07-011-119/+116
