Bug fixes:
- Fix OSC8 format strings (backslash escape layering) in modern-backend.org
- Test format string had single backslash instead of double, causing
unclosed CL string that cascaded through 3 subsequent test forms
- Implementation format string had leading escaped quote (not a string
opener) and triple-backslash ending (also not a string terminator)
- Fix missing closing parens in border-char-rounded and border-char-double tests
- Fix ASDF input-tests pathname (file lives in tests/, not src/components/)
New features:
- Implement suspend-backend / resume-backend protocol methods
- modern-backend: exit/enter alt screen, re-enable mouse/kitty/bracketed-paste
- simple-backend: no-ops (no terminal state to preserve)
Infrastructure:
- Update test suite to cover suspend/resume (backend + modern-backend suites)
- 454 checks, 100% pass across 14 test suites
The combined org file had no unique content — all prose and code were
already in scrollbox.org, tabbar.org, and container-package.org. The
old file's code blocks had the pre-bugfix render/draw-scrollbars
versions and all had :tangle no.
Also update README.org and ARCHITECTURE.org references from
scrollbox-tabbar.org to the individual org files.
New module: src/rendering/framebuffer.lisp (tangled from org/framebuffer.org)
- framebuffer-backend class: implements backend protocol by writing to
2D cell array instead of emitting escape sequences
- cell struct: per-cell state (char, fg, bg, bold, italic, underline, link-url)
- make-framebuffer / framebuffer-width / framebuffer-height
- draw-text, draw-rect, draw-border, draw-link, draw-ellipsis methods
- diff-framebuffers: compares two framebuffers, returns changed cells
- flush-framebuffer: diff + output changes to real backend
- with-scissor macro: clip drawing operations to rectangle
- cursor-move: added default no-op method for all backends
- 20 new tests, all passing (372 total)
Version bumped from 0.11.0 to 0.13.0.
License field set to GPL-3.0 in ASDF.
- Box class with border-style, title, fg/bg slots
- render-box dispatches through backend protocol
- draw-border for borders, draw-rect for background
- draw-text for title below top border
- 7 tests: defaults, border, background, title, no-border,
zero-size, minimum-size
- 13 assertions, 100% GREEN
- ASDF updated with src/components module
- modern-backend now accepts :output-stream initarg
