dart_gp_tab_reader 0.3.0

Pure-Dart, read-only reader for Guitar Pro tablature files (GP3, GP4, GP5, GP6 .gpx and GP7/GP8 .gp). Parses them into a Song > Track > Measure > Voice > Beat > Note tree.

0.3.0

• Guitar Pro 6 (.gpx) support. parseGp now decodes the proprietary BCFS/BCFZ container (lib/src/gpx_reader.dart, bit-level LZ decompressor + sector filesystem, ported from alphaTab's GpxFileSystem) and feeds the inner score.gpif to the GPIF reader. New export: parseGpx.
• GPIF reader: GP6 percussion notes (Element/Variation properties) are now mapped to GM drum keys, matching the GP7/8 articulation handling.

0.2.0

• Guitar Pro 7/8 (.gp) support. parseGp now detects the zip-based .gp container by its bytes and parses the Content/score.gpif GPIF XML score into the same Song tree as the GP3–5 readers. Covered: metadata, tempo (incl. mid-song tempo automations, mapped to MixTableChange.tempo), per-track tuning/capo/GM program/volume/pan, mid-song sound switches (Sound automations → MixTableChange.instrument), percussion articulation mapping to GM drum keys, time signatures, repeats, section markers, anacrusis (pickup) bars, rests, ties, dead/ghost notes, palm mute, let ring, hammer-on/pull-off, slides, bends, harmonics, vibrato, slap/pop/tap and dynamics. Grace beats are skipped (they carry no bar time in GPIF).
• New exports: parseGp7 (zip container) and parseGpif (bare score.gpif XML, useful for GP6 .gpx payloads unpacked by other means).
• GP6 .gpx (BCFS/BCFZ container) is still not decoded, but is now rejected with a clear GpException instead of an "unsupported version" error.
• New dependencies: archive, xml.

0.1.1

• Added dartdoc comments across the public API (models.dart): every model class, enum, constructor and key field is now documented (≈99% coverage).
• No functional changes.

0.1.0

• Initial release.
• Pure-Dart, read-only reader for Guitar Pro GP3, GP4 and GP5 files.
• Parses into a Song → Track → Measure → Voice → Beat → Note tree.
• Dart port of PyGuitarPro; the binary parsing logic mirrors it closely. Test fixtures and the reference dump are taken from the PyGuitarPro test suite.
