* md2html: render linked .md via the about view, fix relative baseJason A. Dönerfield3 days2-26/+45
| | | | | | | | | | | | | | Links to markdown files now point at /<repo>/about/<path> (rendered through the about-filter) instead of /<repo>/tree/<path> (raw blob), so clicking a README link to another .md shows rendered markdown. Also resolve relative links against the rendered file's own directory: about-formatting.sh now forwards the filename cgit passes ($1) to md2html as argv[1], and md2html uses dirname(argv[1]) as the base. This makes links *inside* a rendered subpage (docs/foo.md -> ./bar.md, ../README.md, images) resolve correctly. Non-markdown files and directories still go to tree/; images to plain/; about/ links carry no ?h= since the about view renders against the configured readme ref.
* md2html: rewrite relative README links to the tree/ blob URLJason A. Dönerfield3 days1-11/+60
| | | | | | | | | | | | The image-rewrite patch only fixed relative <img src>; relative <a href> links (e.g. [docs/x.md](docs/x.md)) were still resolved by the browser against the about/summary page URL, not the repo root, so they 404d. Rewrite relative <a href> to absolute cgit URLs the same way: in-repo path -> /<repo>/tree/<path>?h=<branch> ../sibling -> resolved against the repo URL location (/<sibling>) Fragments are preserved; anchors, absolute, scheme and query-only URLs are left untouched.
* md2html: let bullet/1. lists interrupt paragraphs (GitHub-style)Jason A. Dönerfield3 days1-0/+55
| | | | | | | | | | | | | | | | Python-Markdown, unlike CommonMark/GitHub, refuses to start a list that immediately follows a paragraph line without an intervening blank line, so a very common README shape renders as one run-on paragraph: Passing: - foo - bar Add a preprocessor that inserts the blank line when a bullet (- * +) or a 1./1) ordered marker follows a paragraph line, restoring GitHub behavior. Only '1' interrupts for ordered lists (matching CommonMark) so prose like '... the year\n1985. was ...' is not turned into a list. Fenced/indented code and lines already inside a list are left untouched.
* md2html: rewrite relative image links to the plain/ blob URLJason A. Dönerfield6 days1-3/+28
| | | | | | | | | A README's relative image paths (screenshots/foo.png) are repo blobs that cgit only serves via its plain command, but a browser resolves a relative <img src> against the about-page URL, so the image 404s. Rewrite relative <img src> to an absolute /<repo>/plain/<path>?h=<branch> URL using the CGIT_REPO_URL / CGIT_REPO_DEFBRANCH environment cgit gives the about-filter. Absolute so it also works with ui-summary readme rendering.
* md2html: use proper formatting for hrChristian Hesse2021-05-121-5/+1

* auth: add basic authentication filter frameworkJason A. Donenfeld2014-01-161-0/+225
| | | | | | | | | | | | | | | | This leverages the new lua support. See filters/simple-authentication.lua for explaination of how this works. There is also additional documentation in cgitrc.5.txt. Though this is a cookie-based approach, cgit's caching mechanism is preserved for authenticated pages. Very plugable and extendable depending on user needs. The sample script uses an HMAC-SHA1 based cookie to store the currently logged in user, with an expiration date. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

* filters: Improved syntax-highlighting.pyStefan Tatschner2014-01-131-19/+33
| | | | | | | | | | | | | | | | - Switched back to python2 according to a problem in pygments with python3. With the next release of pygments this problem should be fixed. Issue see here: https://bitbucket.org/birkenfeld/pygments-main/issue/901/problems-with-python3 - Just read the stdin, decode it to utf-8 and ignore unknown signs. This ensures that even destroyed files do not cause any errors in the filter. - Improved language guessing: -> At first use guess_lexer_for_filename for a better detection of the used programming languages (even mixed cases will be detected, e.g. php + html). -> If nothing was found look if there is a shebang and use guess_lexer. -> As default/fallback choose TextLexer.
