* Char-mode input: deliver real keystrokes (BS/DEL, whole UTF-8, raw ESC); fix NAWS lost at logon Five input-path fixes that make raw-keystroke (get_char) applications viable, found by building the LPC TUI library on top of them: - comm.cc: char mode delivered "" for Backspace/Delete (the byte was zeroed before delivery, making BS/DEL/NUL indistinguishable). The literal byte is now delivered; line-mode in-buffer editing unchanged. - comm.cc: char mode delivered one *byte* per callback, splitting a multi-byte UTF-8 character into 2-4 invalid one-byte strings. Extraction is now UTF-8 aware: a complete sequence arrives as one callback carrying one valid character; malformed bytes still go byte-at-a-time (no stalls). - comm.cc: the "no ansi" + "strip before process input" ESC->space rewrite (both default on) also applied to char mode, so arrow keys arrived as literal "[A". The rewrite is an anti-ANSI-injection protection for line-mode commands; char mode now always passes ESC through. - net/telnet.cc: each received chunk was u8_sanitize()d independently, so a UTF-8 character split across TCP segments became U+FFFD in any input mode. An incomplete trailing sequence (new u8_incomplete_tail(), GTest-covered) is now carried over in interactive_t and prepended to the next chunk. - net/telnet.cc + comm.cc: fast clients answer the initial DO NAWS while ip->ob is still the master object, so the window_size apply fired on the wrong object and the size was lost until the next resize. The last report is cached and replayed on the user object at logon. docs/efun/interactive/get_char.md documents the delivery contract.

Everything below terminal.lpc is a pure state machine: 194 checks in single/tests/std/tui/ cover the decoder, editor sessions, history search, screen diffing and widgets headlessly. `tuidemo` / `tuidemo app` (command/tuidemo.lpc) demo both modes over any telnet client; the whole stack was verified end-to-end over a live connection including split-packet UTF-8, modifier keys, paste, resize and alternate-screen teardown. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01RpXv4yGCWpkzbkifyZy9EE * /std/tui v2: pterm/blessed-inspired widgets, inline printers and prompts, showcases Reviewed the pterm (Go) and blessed widget catalogs and ported what earns its keep in a MUD; DESIGN.md is renamed to README.md and documents the full set (including what was deliberately not ported). New layers: - print.lpc — pterm-style printers that compose with plain write(): p_table (boxed, width-aware, header rule), p_tree, p_bars, p_spark, p_panel, p_bullets, p_header, p_progress, p_info/success/warn/error, and p_bigtext via the existing /std/bitmap_font. - menu.lpc + terminal glue — inline interactive prompts in the normal output flow: tui_select(), tui_multiselect() (Space toggles, list windows by height, collapses to a "? prompt: answer" line) and tui_confirm() (y/n with a default). New widgets (/std/tui/w/): table (columns + header + selection), tree (collapsible, arrows fold), checklist, radiolist, button, progress, spinner (app-driven tick()), and log (bottom-anchored scrollback pane). Showcases (command/tuidemo.lpc): `tuidemo select` (prompt chain), `tuidemo print` (all printers), `tuidemo dashboard` (animated spinner, progress bars, sparkline, live table and log on a call_out tick), and `tuidemo form` (textfield, radio group, checkboxes, buttons). Coverage: three new test files (print exact-output, menu sessions, widgets2) bring /std/tui to 8 files in the suite; the live-connection e2e run now drives all six showcases end-to-end (52 checks), including the select->multiselect->confirm chain, unattended dashboard animation, and full form entry. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01RpXv4yGCWpkzbkifyZy9EE * /std/tui: charts — braille canvas, line charts, vertical bars, heatmap Fills the chart gap left by v2 (only the horizontal p_bars existed): - canvas.lpc: a braille dot canvas (each cell is a 2x4 dot grid from the U+2800 block — the blessed-contrib/drawille technique), giving sub-cell resolution: c_set/c_unset/c_get, Bresenham c_line, and c_plot (scale a value series across the canvas), with per-cell colour. Renders as a string, per-row strings, or per-cell ({ ch, attr }) pairs for blitting into a screen. - print.lpc: p_chart (multi-series braille line chart with y-axis gutter and coloured legend), p_vbars (vertical bar chart with eighth-block partial tops and optional value row), p_heatmap (2D matrix as 256-colour cells, cool-to-hot ramp, optional axis labels). - w/chart.lpc: the live line-chart widget — add_series()/add_point() rolling history sized to the widget, auto or fixed y-range; replaces the dashboard's sparkline label with a real animating graph. - `tuidemo charts` showcase; chart docs in README.md and the docs page (heatmap removed from the not-ported list). Tests: single/tests/std/tui/charts.lpc pins the braille bit math with exact glyphs, line drawing, plot endpoints, exact p_vbars output, chart/heatmap structure, and the widget's rolling window. The live e2e run verifies `tuidemo charts` output and braille frames streaming from the dashboard chart. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01RpXv4yGCWpkzbkifyZy9EE * docs: move the TUI page from Concepts to STDLIB /std/tui is a mudlib library like base64/break_string/json, so its page belongs under docs/stdlib/ with the rest of the /std modules, not under Concepts. Registered in stdlib/index.md; README file-layout pointer updated. (Concepts' sidebar is autogenerated, so the old entry disappears with the file.)

FluffOS Documentation
This directory contains the source for the FluffOS documentation site, published at https://www.fluffos.info.
The site is built with Docusaurus 3 (@docusaurus/preset-classic).
Markdown files live directly in this directory (the docs plugin is configured with
path: '.' and routeBasePath: '/'), so docs/efun/strings/explode.md becomes
/efun/strings/explode on the site.
This README is for contributors and is excluded from the published site (see
excludeindocusaurus.config.ts).
Local Development
Requires Node.js 18+ (Node 22 recommended).
cd docs
npm install
npm run dev # dev server on http://localhost:3000
Other scripts:
npm run build # production build → docs/build/
npm run preview # serve the production build locally
npm run clear # clear the Docusaurus cache
Search
Full-text search is provided by
@easyops-cn/docusaurus-search-local,
an offline/local search theme — the index is generated at build time and shipped with the
site, so no external search service (e.g. Algolia) is needed.
Notes:
- The search index is only generated by
npm run build. In the dev server (npm run dev) the search bar shows a hint instead of results; usenpm run build && npm run previewto test search locally. - Both English and Chinese (
zh-CN/) pages are indexed (language: ['en', 'zh']). - Search options live in the
themessection ofdocusaurus.config.ts.

| Script | Purpose |
|---|---|
update_index.sh |
Regenerates all generated index.md listing pages (calls gen_index.py) |
gen_index.py |
Writes an index.md for one doc tree (e.g. ./gen_index.py efun EFUN) |
gen_config_docs.py |
Regenerates driver/config.md from src/base/internal/rc.cc |
add_missing_efuns.py |
Creates stub pages under efun/general/ for undocumented efuns (needs a keywords.json from the generate_keywords tool) |
Conventions & Gotchas
driver/config.mdis auto-generated fromsrc/base/internal/rc.cc— never edit it by hand. Regenerate withpython3 docs/gen_config_docs.py; CI fails if it is stale..mdfiles are treated as standard CommonMark (markdown.format: 'detect'), but bare{...}in prose is still parsed as a JSX expression and breaks the build — escape it as\{...\}outside fenced code blocks.- Sidebar entries in
sidebars.tsuse doc IDs (relative path without extension), not URLs. - Generated
index.mdlisting pages (efun/apply/stdlib/cli/concepts/driver/zh-CN) are rewritten by./update_index.sh— regenerate rather than hand-edit them.lpc/index.mdis hand-written and deliberately not regenerated. onBrokenLinksis set to'throw': a broken internal link fails the build (and the Pages deploy) instead of shipping a 404.
