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.

Replace the writer spin lock with a blocking mutex

2026-10-15T09:37:10+00:00

term_write_begin spun on an atomic sequence word. A waiter burned CPU, and with no priority inheritance a SCHED_FIFO waiter could starve a preempted holder on the same CPU. The writer section is now a pthread mutex with PTHREAD_PRIO_INHERIT where the platform has it, and an SRWLOCK on Windows. Re-entry on the owning thread still only counts the depth. The platform wrapper (init, lock, unlock, destroy) is in compat.h. term_new initializes the mutex, and term_free destroys it. Meson links the thread library into the core, term_dep, and term_internal_dep. The README, term.h, and the amalgamation note say that POSIX needs -pthread. Tests: the feed and snapshot thread test now checks the final screen and history against a serial reference. A new test checks that term_lock nests and that another thread waits for the last term_unlock. Co-Authored-By: Claude Haiku 5.5

Take the terminal name from term_options.name

2026-10-15T09:30:14+00:00

The core hard-coded "wsap_term" for XTVERSION, the XTGETTCAP TN and name default, and the OSC 9 notification title. A headless library should take its identity from the host. term_options.name sets the name. NULL or "" selects "term". term_new() copies it and returns NULL unless it is 1 to 63 printable ASCII bytes, since DCS replies echo it. A DCS +p still changes the TN value, and the XTVERSION and notification defaults keep the host name. Co-Authored-By: Claude Haiku 5.5

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.

- 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

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
