markup: map fossil site-relative links; theme-neutral pikchr ink
Two bugs found by browsing real content on a phone. Imported wiki/technote/forum bodies are full of fossil's own routes (libfossil's wiki alone: 500 /finfo, 211 /dir, 105 /timeline, 23 /doc). Quarry passed those hrefs through verbatim, so libfossil's home page offered a README.md link that went nowhere. Resolver grows ResolvePath: /doc/<ver>/<path> maps to quarry's file route, /info to the artifact, /timeline /wiki /forum /technote to their pages; a verb quarry has no page for drops the link and keeps the label, since a dead link is worse than plain text. file.get now lets zit resolve symbolic versions (trunk, tip, tags) instead of demanding a hash — that is what /doc links use, and zit is the authority on names. The href rewrite runs BEFORE reference resolution so the two passes never see each other's output. Pikchr hardcodes rgb(0,0,0), which is invisible on quarry's dark theme — the DOM assertions all passed while the diagram was unreadable, and only a screenshot caught it. Its default ink now becomes currentColor so a diagram follows the page theme; author-specified colours are untouched. Fossil solves this with a server-side --dark-mode flag, which cannot work for a CSS-themed page. check-in: 1d680372e5 user: dmestas tags: trunk | |

markup: Pikchr diagrams via WebAssembly (fossil's third markup)
pikchr.c built to a standalone WASI module (-DPIKCHR_SHELL -sSTANDALONE_WASM) and run under wazero, so the CGO-free constraint holds. Its own CLI reads - and writes SVG, so the host ABI is a pipe: no memory marshalling to get wrong. Renders text/x-pikchr artifacts and pikchr fences inside markdown; a diagram that will not compile degrades to its source plus the compiler's message. SVG does NOT ride the document policy. It gets a narrow allow-list derived by enumerating what the module actually emits (six elements, a closed geometry/paint attribute set, no script/href/foreignObject), so even a hole in Pikchr's own label escaping cannot reach a page. Fence placeholders are alphanumeric with a per-render nonce: an HTML parser rewrites control bytes, so a NUL-based marker does not survive sanitizing (caught by test). Provenance and the rebuild recipe are in the ledger. check-in: 58fe4cf214 user: dmestas tags: trunk | |

markup: render Fossil wiki format; fix mimetype dispatch; GFM completeness
An absent N card means text/x-fossil-wiki, not markdown — fossil's wiki_render_by_mimetype is explicit — but quarry rendered those as markdown, mangling 217 of libfossil's 443 wiki artifacts ([target|label] links came out as literal text). Adds a Fossil wiki renderer (the seven rules from fossil's own wiki.wiki: paragraphs, single-level * and # lists, indented paragraphs, [target|label] links through the existing Resolver, verbatim/nowiki, HTML pass-through gated by the sanitizer), dispatches on mimetype exactly as fossil does, and stores forum posts' N card so they dispatch too. Fossil site-relative targets quarry cannot serve render their label as text rather than showing wiki source. Also GFM completeness: footnotes and auto heading IDs, with the sanitizer policy widened to admit what goldmark actually emits (a footnotes div, not section — caught by test). check-in: 45c96a506b user: dmestas tags: trunk | |
