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.

Eliminate pen style and history stream parameter smuggling

2026-10-13T11:46:44+00:00

- Introduce struct text_pen bundling (fg, bg, sl) across screen and core - Reduce text_append from 9 to 7 parameters - Reduce text_commit from 8 to 6 parameters - Reduce hist_runs_add_pen from 5 to 3 parameters - Reduce sc_text_ascii and sc_ascii_fast from 6 to 4 parameters - Remove unused fg, bg parameters from mark_row_blank - Introduce struct hist_stream_state in src/hist.c, reducing stream_lines from 9 to 5 params and lf_rows from 10 to 6 params - Introduce struct hist_view_pos in src/hist_view.h, reducing term_hist_view_row_pos from 9 to 7 params

Encapsulate stream queue context and consolidate forwarding wrappers

2026-10-13T11:27:58+00:00

- Create struct stream_emit_ctx packing stream queue arguments into 1 cache line - Reduce emit_stream_bulk_wrapped from 13 parameters to 3 - Reduce flush_stream_queue from 10 parameters to 1 - Extract stream_queue_finish to eliminate duplicated cleanup in kernel instantiations - Replace EMIT_STREAM_ROW macros with typed inline functions - Move pending_wrap clearing directly into term_screen_erase, insert, delete, and scroll - Remove sc_erase_display, sc_erase_line, sc_insert_chars, and sc_delete_chars wrappers - Consolidate term_row and remove duplicated row_fill_gap helper

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

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
