Tcl/Tk, PDF, Markdown, and Cairo development.

Pure-Tcl applications and libraries with a shared intermediate representation. The apps interoperate — right-click in mdhelp or man-viewer to look up a word in tcltk-glossary; settings and tool paths are shared via ~/.tcldocs.rc.

Pre-1.0 — refinements in progress, breaking changes possible.

Apps

• mdhelp — Markdown viewer / editor with PDF export and full-text search
• man-viewer — nroff viewer, CLI converters (n2html / n2md / n2pdf / n2svg / n2txt), and nroffide (nroff IDE with debugger)
• tcltk-glossary — SQLite-backed Tcl/Tk glossary with FTS5 search, GUI and TUI
• cheatsheets — cheatsheet renderer (CSD format → PDF / HTML / Markdown via docir)

Libraries

• docir — document intermediate representation and renderer family (HTML, PDF, Markdown, nroff, SVG, canvas, tile)
• mdstack — Markdown parser, viewer, and renderers (adapter on docir)
• tcldocs-config — cross-app shared settings (~/.tcldocs.rc)
• tcldocs-launcher — cross-app tool launcher (Tools menu, app autodetect)
• tcldocs-search — cross-app search component for the documentation suite

Tools

• tcltk-manindex — Tcl/Tk manpage indexer with FTS5 search and auto-generated cheatsheets
