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.

Reject a scrollback above TERM_SCROLLBACK_MAX

2026-10-15T09:40:44+00:00

term_new() silently cut a scrollback above 1000000 lines to 1000000. The limit now has a name in term.h, and term_new() returns NULL above it, as it does for the other invalid options. Co-Authored-By: Claude Opus 5.5

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

Reject invalid arguments instead of ignoring them

2026-10-15T09:29:35+00:00

term_feed() returns bool and rejects a NULL terminal, a NULL buffer with a nonzero length, and any flag bit it does not know. Unknown bits are rejected now so that later flags can be added without changing what the old calls mean. term_new() returns NULL for a negative size component, columns above TERM_MAX_COLS, a negative scrollback, or a cursor style outside the enum. Zero still selects the default size and scrollback. It no longer clamps bad values silently. term_resize() rejects columns above TERM_MAX_COLS instead of clamping them, which matches how it already rejects a size below 1.

Add soversion, version macros, and reserved term_options words

2026-10-15T09:29:25+00:00

The shared library now carries its major version in the SONAME (libterm.so.0), so an ABI break gets a new file name. The header gains TERM_VERSION, TERM_VERSION_MAJOR/MINOR/PATCH and TERM_VERSION_CODE, and term_version() returns the code the library was built with. A test checks the macros against meson.build's project version and against the runtime value. term_options ends with uint32_t reserved[8]. term_new() returns NULL if a word is nonzero, so later versions can give those words a meaning without misreading a caller's leftover data. All-zero options stay valid. 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.
