* 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

### abcMIDI package
|
|
|
|
[](https://github.com/keryell/abcmidi/actions/workflows/test.yml)
|
|
|
|
abcMIDI is a package of programs written in C for handling [abc music notation](http://abcnotation.com/) files. The software was created by James Allwright in the early 1990 and presently maintained by Seymour Shlien. It initially included the following programs:
|
|
|
|
1. abc2midi for converting an abc file to a midi file,
|
|
2. abc2abc for transposing abc notation to another key signature,
|
|
3. midi2abc for creating an abc file from a midi file,
|
|
4. yaps for producing a PostScript file displaying the abc file in common music notation and,
|
|
5. mftext for creating a text representation of a midi file.
|
|
|
|
Seymour added two more programs:
|
|
|
|
1. abcmatch for finding common elements in a collection of abc tunes and,
|
|
2. midicopy for copying parts of a midi file to a new midi file.
|
|
|
|
Yaps has been superceded by [Jef Moine](http://moinejf.free.fr/) abcm2ps and abc2svg programs. Midi2abc has been expanded to include mftext and various other features for supporting the [runabc](https://ifdo.ca/~seymour/runabc/top.html) application. Abc2midi has numerous new features that are described in its own web page [abc2midi guide](https://abcmidi.sourceforge.io).
|
|
|
|
Components of the abcMIDI package are parts of numerous applications for creating and editing abc files. Compilations of these components for various operating systems can be found on [The ABC Plus Project](http://abcplus.sourceforge.net/) web page.
|
|
|
|
|
|
The latest version of the abcMIDI package supported by James Allwright can be found can be found [here](http://abc.sourceforge.net/abcMIDI/original/). More recent versions can be found on [sourceforge](https://sourceforge.net/projects/abc/) and on the [runabc](https://ifdo.ca/~seymour/runabc/top.html) web page.

### Building
|
|
|
|
#### Autoconf (legacy)
|
|
|
|
The traditional build uses autoconf:
|
|
|
|
```sh
|
|
./configure
|
|
make
|
|
sudo make install
|
|
```
|
|
|
|
#### CMake (modern)
|
|
|
|
A CMake build system is available alongside the legacy one, with
|
|
[presets](https://cmake.org/cmake/help/latest/manual/cmake-presets.7.html)
|
|
for common configurations:
|
|
|
|
```sh
|
|
# Configure and build (pick a preset: default, debug, sanitize)
|
|
cmake --preset default
|
|
cmake --build --preset default
|
|
|
|
# Install
|
|
cmake --install build/default
|
|
```
|
|
|
|
Available presets:
|
|
|
|
| Preset | Build type | Description |
|
|
|------------|------------|----------------------------------------------|
|
|
| `default` | Release | Optimized build |
|
|
| `debug` | Debug | Debug symbols, no optimization |
|
|
| `sanitize` | Debug | Debug + AddressSanitizer + UndefinedBehaviorSanitizer |
|
|
|
|
The CMake build generates `compile_commands.json` for use with
|
|
clangd and other LSP-based editors.
|
|
|
|
### Testing
|
|
|
|
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
|
|
# Run all tests
|
|
ctest --preset debug
|
|
|
|
# Run only golden-file tests / only smoke tests
|
|
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/
|
|
```
