Rename the library to wsap_vtcore

2026-10-15T10:04:01+00:00

ncurses installs and defines struct term. In a file that includes both headers, an ncurses TERMINAL * and this library's terminal are silently the same type. The name wsap_vtcore avoids the clash. The public header is now . Every global symbol uses the wsap_vtcore_ prefix, every macro uses WSAP_VTCORE_, and the shared library is libwsap_vtcore.so.0. The default terminal name is now "wsap_vtcore". The ISA override variable is WSAP_VTCORE_ISA. No other behavior changes. The amalgamation writes wsap_vtcore.c and wsap_vtcore.h.

Report selection allocation failure instead of truncating

2026-10-15T09:42:11+00:00

On a screen taller than 256 rows the selection's row list is allocated. When that failed, it fell back to the 256-entry stack array, so the selection and the snapshot's selection spans silently stopped at row 256 while every call still reported success. lines_init() now reports the failure. term_select_start() and term_select_extend() return false and leave the selection unchanged, term_snapshot_update() fails and keeps its previous content, and the text getters return NULL, as they do for their other allocations.

Keep installed headers from shadowing or polluting host names

2026-10-15T09:31:21+00:00

The pkg-config file put include/term on the host's include path, so ncurses' term.h could be picked up in place of ours. Hosts now write and the package adds only its include directory. The installed Unicode API had unprefixed names that collide with host symbols and macros. Rename them: term_ for functions, types, and static tables, TERM_ for macros and include guards. unicode_data.inc and tools/generate_unicode.py are renamed to match. The generator's inputs here are Unicode 15.1 and the checked-in table is 18.0.0, so the table data was not regenerated. Only the declarations were checked against the generator. utf8.h casts the malloc result so it compiles as C++. header_test.sh now includes with only include/ on the path. It also checks that a host which defines unicode_width, UTF8_ACCEPT, GRAPHEME_MAX_LEN, in_ranges, and similar names compiles with the Unicode headers as C11 and C++, in both declaration orders.

Return owned text and share cell attribute flags with snapshots

2026-10-15T08:37:31+00:00

Make text queries return allocated strings released with term_text_free, keeping each capture atomic. Align public attributes with the write core, remove snapshot conversion tables, and migrate tests and the Kitty adapter.

Remove unused private functions and inline trivial helpers

2026-10-14T14:17:43+00:00

Replace scalar loops with SIMD spans, packed stores, and direct wrap-pad checks

2026-10-13T16:41:47+00:00

Optimize screen scrolling, SIMD wrap padding, and reflow loops

2026-10-13T11:10:31+00:00

- Batch full-screen scroll rotations, eliminating row-by-row scroll loops - Use block memmove for sub-region scrolling, eliminating heap/stack row swaps - Vectorize CELL_WRAP_PAD flag setting with AVX2/SSE2/NEON in screen.h - Replace scalar tab-stop loops with 64-bit word stamping - Optimize active row backwards scan in resize and erase mode 2

Optimize and simplify loops, table lookups, and branchless parsers

2026-10-13T10:36:27+00:00

- Replace sequential colon-counting loop with branchless CTZ bitmask in src/pen.h - Replace linear strchr with 256-bit ASCII punctuation bitmask in src/selection.c - Flatten 3D color cube loop and precompute constants in src/palette.c - Use static 256-byte LUT for hex decoding and bsearch for termcap in src/escape.c - Replace capacity doubling while loops with branchless CLZ pow2 helpers across core - Use direct memset/memcpy in src/snapshot.c - Optimize input digit/byte formatting, alt-prefix path, and make keyboard state optional in src/input.c

term: move the term core to subprojects/term

2026-10-12T14:49:34+00:00

The core now builds, tests, and benchmarks alone, as a Meson subproject with no dependency on the main tree. - include/term/ holds term.h and the header-only unicode/. src/ holds the core and its private headers. The main tree gets only include/term through term_dep, so it cannot reach a private header. - The term tests, the term benchmarks, the Kitty parser suite, and tools/amalgamate.py and tools/generate_unicode.py move with it. The tests run as term:. - The main build passes its -march (arch_flag) and b_ndebug to the subproject. A directory configured before this commit needs meson configure -Dterm:arch_flag=-march=... once. - The term tests compile with -UNDEBUG. They do work inside assert. - The subproject exports term_test_dep with term_api.h, for the main tree's render, thumbnail, color, and selection tests. - The Kitty bridge used struct vector2i and has not compiled since the public API redesign. It builds again. 2 of its 14 tests fail: REP after a tab, and a cursor report after a resize. - dirgraph.py drops the term and unicode layers. Its self-test uses pty. - The symbols test ignores the __odr_asan symbols that ASan adds. Co-Authored-By: Claude Opus 5.5
