The preset file declared "version": 6 (cmake >= 3.25), causing
"Unrecognized 'version' field" on cmake releases as common as the
3.22.1 shipped by Ubuntu 22.04 LTS. None of the v4/v5/v6 schema
features are used here -- the file only relies on
configurePresets/buildPresets/testPresets with cacheVariables,
binaryDir, displayName, output.outputOnFailure, and environment.
v3 (cmake >= 3.21) is the lowest schema where "generator" remains
optional so cmake can pick a default; v2 would have required adding
"generator" to every preset.
cmakeMinimumRequired lowered from 3.25 to 3.21 to match.
Verified locally that all three presets (default, debug, sanitize)
configure, build, and pass ctest --preset default (19/19 tests).

Emitting a Marker meta-event from the PART case wrote the event with
delta_time_track0 (correct, since that's the conductor-track accumulator)
but did not also reset delta_time. On track 0 in multi-track mode,
delta_time also accumulates via timestep() and is what writetrack()
returns to the MIDI library as the end-of-track delta — so each marker
left a stale delta_time that pushed the end-of-track event past the end
of the music. In single-track mode (ntracks == 1), markers were written
with delta_time_track0 too, but delta_time is the only relevant counter
in that mode, so notes following each marker were shifted later.
Fix: mirror the TEMPO handler — on ntracks == 1 use delta_time and reset
it; on ntracks != 1 keep using delta_time_track0 for the event delta but
also zero delta_time so the end-of-track is not inflated.
Reported by James Allwright with the partdemo.abc test case (now in
samples/), which exercises the parts != -1 path (header P:BACDBAC plus
body P: labels A/B/C/D). James independently fixed the same bug in his
abc2midiu fork in r32 (commit 34b7c32, "Add -PMAR option for part
markers"), where the equivalent reset is on the single delta_time
counter — his fork having retired delta_time_track0 in an earlier
refactor. Verified that mftext output of the generated MIDI is now
byte-identical to the non-PMAR output except for the added Marker
events, on both partdemo.abc (single-track) and samples/demo.abc tune 5
with P:(AB)3 (multi-track).
Add a CMake/CTest regression test (abc2midi_pmar_partdemo) that locks in
the post-fix mftext output. To support it, add_golden_test() gains an
optional NAME (to register multiple tests against the same TYPE+SAMPLE
pair) and an optional ABC2MIDI_ARGS (forwarded to the abc2midi
invocation in run_via_mid). Reverting the genmidi.c fix makes the new
test fail; reapplying it makes it pass.
- abc2midi 5.03 (April 2026): bumped #define VERSION in store.c to reflect this branch's accumulated fixes
(error exit status, missing C:/R:/X: header emission, %%MIDIdef macros allowed anywhere) plus the
build-system additions.
- Single source of truth for the package release date: the VERSION file is now consumed by both build
paths.
- CMakeLists.txt reads it via file(STRINGS VERSION ABCMIDI_VERSION ...); the previously hard-coded
project(VERSION 2026.02.24) (an unused PROJECT_VERSION) is dropped because the date format isn't
MAJOR.MINOR.PATCH.
- configure.ac uses m4_esyscmd_s([cat VERSION]) in AC_INIT, replacing the very stale hard-coded
2011-08-03.
- The two build paths remain independent — no cross-generation between CMake and autoconf.
- Test normalization fix (tests/run_test.cmake): the version-banner regex now requires a capitalized month
and accepts a date with or without a day number. The previous regex was lowercase-permissive and silently
ate PostScript lines like 0.5 setlinewidth 0 0 moveto in yaps output — tests/golden/yaps_coleraine.txt is
regenerated to reflect the now-correctly-preserved PostScript.
- Docs:
- doc/CHANGES: April 25 2026 entry covering the version bump and VERSION-file unification.
- doc/readme.txt: per-tool listing updated (abc2midi 5.03 April 2026, midistats 1.03 February 20 2026
synced to source).
- doc/abc2midi.1: header label bumped to 5.03 April 2026 (content not audited).
- README.md: new Maintainers / releasing section documenting the release procedure, including the
requirement to run autoreconf -f so the committed configure picks up the new AC_INIT arguments.
* abc2midi: allow %%MIDIdef macros to be defined anywhere
Fix also some lost CHANGES from previous commit.
abc2midi: allow %%MIDIdef macros to be defined anywhere, including before the first X: field (outside any tune). Previously %%MIDIdef was only handled inside event_specific() after the started_parsing check,so macros defined in the file header were silently ignored.
The %%MIDIdef handling has been moved before the started_parsing check in event_specific() in store.c since macro definitions are context-independent.
* Update the golden test files since X:, R: and C: are now emitted
* Add configuration for CMake build system alongside autoconf
- Add a modern CMake build system (`CMakeLists.txt`, `CMakePresets.json`) that coexists with the legacy
autoconf/Makefile build
- Shared source files (`midifile.c`, `parseabc.c`, `music_utils.c`, `parser2.c`) are compiled once via OBJECT
libraries and linked into the 8 binaries
- Three presets: `default` (Release), `debug`, `sanitize` (ASan + UBSan)
- Generates `compile_commands.json` for clangd/LSP editor support
- Install rules match the legacy Makefile (binaries, doc files, man pages)
- Pinned to `-std=gnu89` because the codebase mixes K&R `()` and ANSI typed prototypes — in C23/gnu23 (GCC 15+
default), `()` means `(void)`, making these a hard error. Note: **the existing autoconf build is also broken with
GCC 15** for the same reason
```sh
cmake --preset debug
cmake --build --preset debug
cmake --install build/debug --prefix /usr/local
Documentation
- README.md: added Building section with both autoconf and CMake instructions
- doc/readme.txt: added build instructions in the existing preamble
- doc/CHANGES: added changelog entry
Test plan
- All 3 presets configure and build with GCC 15
- Smoke test: abc2midi samples/coleraine.abc produces valid MIDI through mftext
- Sanitizer build (--preset sanitize) runs clean on sample files
- Install layout verified: 8 binaries, 10 doc files, 8 man pages in correct paths
- Build on macOS (untested, should work with AppleClang)
* Implement basic testing infrastructure
The CMake build includes a test suite covering all 8 programs:
- **Smoke tests** verify each binary runs cleanly with `-ver`.
- **Golden-file tests** run each program on a sample input and compare the
(normalized) output to a checked-in reference. Binary MIDI outputs are
piped through `mftext` to produce diffable text. Volatile lines (version
banners, dates, temporary paths) are stripped before comparison.
```sh
ctest --preset debug
ctest --preset debug -L golden
ctest --preset debug -L smoke
```
To regenerate the golden files after an intentional behavioural change,
review the diff, then commit:
```sh
cmake --build build/debug --target update-golden
git diff tests/golden/
```
* Factorize more the test CMake code
* Add GitHub Action to run the CI and output a status badge
* Add GitHub Action workflow dispatch to allow running from the UI

complex build systems.

* Update changelog and comments

* Factorize more the test CMake code
* Add -PMAR option to output `P:` information as MIDI part meta-event
* Update man page and comments
* Add the instance number of a part like `Part T-4`
