10 daysRewrap header comments that the rename pushed past 80 columnsBerke Güzel

10 daysRename the library to wsap_vtcoreBerke Güzel
ncurses installs <term.h> 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 <wsap_vtcore/wsap_vtcore.h>. 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. Co-Authored-By: Claude Haiku 5.5 <noreply@anthropic.com>
10 daysReport selection allocation failure instead of truncatingBerke Güzel
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.

10 daysReject a scrollback above TERM_SCROLLBACK_MAXBerke Güzel
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 <noreply@anthropic.com>

10 daysKeep the snapshot unchanged when an update failsBerke Güzel
term_snapshot_update converted the viewport in place, so an allocation that failed midway left the snapshot empty and a renderer painted a blank frame. Split the update into two phases. Phase 1 makes every allocation the update needs and counts the arena words the converted rows add, then grows the arena once. Phase 2 writes the view, cells, keys, clusters, and selection, and cannot fail. A failed update now keeps the previous content, and a retry is an ordinary incremental update. invalidate() is removed. The term_snapshot_update comment and the correctness audit now say the snapshot keeps its previous content. The failure test fails each allocation in turn from the same starting state. After every failed call it compares the view, cells, row keys, selection spans, and cluster code points with the state before the call. A retry must succeed and match a fresh capture. The cases are a first update, a 32 by 16 screen of ZWJ families and regional-indicator flags (arena growth), a resize, a 300-row screen (scratch arrays), and a long scroll run.

10 daysReplace the writer spin lock with a blocking mutexBerke Güzel
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 <noreply@anthropic.com>
10 daysKeep installed headers from shadowing or polluting host namesBerke Güzel
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 <term/term.h> 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 <term/term.h> 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.

10 daysTake the terminal name from term_options.nameBerke Güzel
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 <noreply@anthropic.com>
10 daysReject invalid arguments instead of ignoring themBerke Güzel
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.

10 daysAdd soversion, version macros, and reserved term_options wordsBerke Güzel
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 <noreply@anthropic.com>
10 daysDocument snapshot pointer lifetimes and make getters NULL-safeBerke Güzel
The snapshot getters crashed on a NULL snapshot, unlike the rest of the API. They now return NULL, an empty span, 0, or write nothing, as the terminal functions do. term_snapshot_cluster writes nothing when cps is NULL or cap is 0. Document that the view and its palette keep their address for the life of the snapshot, and that a row pointer lasts only until the next update or free, since an update can realloc the cell array. Rename the term_input.h include guard to TERM_INPUT_H to match the file. Co-Authored-By: Claude Haiku 5.5 <noreply@anthropic.com>

12 daysFix extra mouse button encoding collision with Alt bit and document API gapsBerke Güzel
- Encode buttons 8 through 11 (EXTRA_1..4) with offset 128 (128..131) per xterm mouse tracking, resolving collisions with the Alt modifier bit (8) - Drop EXTRA_5 from enum term_mouse_button since xterm mouse tracking defines four extra buttons (8 to 11) and codes beyond 131 collide with modifier bits - Replace literal 3 with TERM_MOUSE_BUTTON_NONE for hover motion check in mode 1002 - Document button field semantics in struct term_mouse_event for press, release, motion, and scroll events - Document OSC 52 target buffer selections ("c", "p", "q", "s", "0".."7") in term.h - Add unit tests for extra button encoding, SGR release, hover motion suppression in mode 1002, and non-collision with Alt modifiers

12 daysterm: move the term core to subprojects/termBerke Güzel
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:<name>. - 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 <noreply@anthropic.com>
