GP5 supports up to 2 voices (e.g., Lead + Bass in one staff). +- **Content**: `beats` (`Vec`). + +#### `Beat` (`lib/src/beat.rs`) +A rhythmic unit containing notes. +- **Rhythm**: `duration` (`Duration` struct), `tuplets`. +- **Content**: `notes` (`Vec`), `text` (lyrics/text above), `effect` (`BeatEffects` - e.g., mix table changes, strokes). +- **Properties**: `status` (Normal, Rest, Empty). + +#### `Note` (`lib/src/note.rs`) +A single sound event. +- **Pitch**: `value` (fret number 0-99), `string` (string index 1-N). +- **Dynamics**: `velocity` (MIDI velocity). +- **Effects**: `NoteEffect` (bend, slide, hammer, harmonic, vibrato, grace note, etc.). +- **Type**: `kind` (Normal, Tie, Dead, Rest). + +## 4. Effects System + +Effects are categorized by where they apply: + +- **Note Effects** (`lib/src/note.rs` -> `NoteEffect`): + - `bend`: `BendEffect` (points, type). + - `grace`: `GraceEffect` (fret, duration, transition). + - `slides`: `Vec`. + - `harmonic`: `HarmonicEffect` (Natural, Artificial, Tapped, Pinch, Semi). + - `hammer`/`pull_off`, `palm_mute`, `staccato`, `let_ring`, `vibrato`, `trill`, `tremolo_picking`. + +- **Beat Effects** (`lib/src/beat.rs` -> `BeatEffects`): + - `stroke`: Up/Down strums. + - `mix_table_change`: Tempo, Volume, Pan, Instrument automation changes. + - `pick_stroke`. + +- **Track Effects**: RSE (Realistic Sound Engine) settings, EQ, Humanize. + +## 5. Low-Level I/O (`lib/src/io.rs`) + +The `io` module provides primitives for reading binary data types used in GP formats: +- `read_byte`, `read_signed_byte`, `read_bool`. +- `read_int` (4 bytes), `read_short` (2 bytes). +- `read_chunk_string`: Pascal-style strings. +- `read_string_byte`: String prefixed by byte length. +- `read_string_int`: String prefixed by int length. + +The parsing is sequential.

Define reader methods in `Song` (e.g., `read_gp6`). +2. Implement version-specific logic in `read_track`, `read_measure`, etc., usually switched by `self.version.number`. + +## 8. For AI Agents (Context) + +When navigating this codebase: +1. **Entry Point**: `lib/src/lib.rs` exports modules. `lib/src/song.rs` contains the `read_gpX` entry methods. +2. **Logic Flow**: `read_gpX` -> `read_version` -> `read_info` -> `read_tracks` -> `read_measures`. +3. **Data Flow**: Measures are stored per track. `song.tracks[t].measures[m]` corresponds to `song.measure_headers[m]`. The header contains timing info (time sig, key sig) shared across all tracks for that measure index. +4. **One-indexing**: GP formats often use 1-based indexing for user-facing values (strings, tracks). Internally, Vectors are 0-indexed. Be careful with loop bounds. + - Note strings: `note.string` is often 1-based in GP data. + - Fret values: 0 is open string, >0 is fret. + +### Common Tasks Patterns +- **Iterating Notes**: + ```rust + for track in &song.tracks { + for measure in &track.measures { + for voice in &measure.voices { + for beat in &voice.beats { + for note in &beat.notes { + // Process note + } + } + } + } + } + ``` diff --git a/cli/src/main.rs b/cli/src/main.rs index c9c202a..c024f16 100644 --- a/cli/src/main.rs +++ b/cli/src/main.rs @@ -1,57 +1,160 @@ use clap::Parser; -use fraction::ToPrimitive; -use scorelib::gp; +use scorelib::gp::Song; +use scorelib::track::Track; use std::path::Path; -use std::ffi::OsStr; use std::fs; use std::io::Read; -const GUITAR_FILE_MAX_SIZE:usize = 16777216; //16 MB, it should be enough +const GUITAR_FILE_MAX_SIZE: usize = 16777216; // 16 MB #[derive(Parser, Debug)] -#[clap(author="slundi", version, about="Perform operation on music files", long_about = None)] +#[clap(author="slundi", version, about="Guitar Pro File Parser CLI", long_about = None)] struct Args { - /// Action - #[clap()] action: String, - - /// Input file - #[clap(short='i', long, help="Input file path")] input: String, + /// Input file path (.gp3, .gp4, .gp5) + #[clap(short, long)] + input: String, + /// Show full tablature for the first track + #[clap(short, long)] + tab: bool, } fn main() { - let args: Args = Args::parse(); - let f = Path::new(&args.input); - //check if path OK, file exists and is file - if !f.exists() || !f.is_file() {panic!("Unable to access file: {}", &args.input);} - //check file format - let ext = f.extension().and_then(OsStr::to_str).unwrap_or_else(||{panic!("Cannont get input file extension");}).to_uppercase(); - let size: usize = fs::metadata(&args.input).unwrap_or_else(|_e|{panic!("Unable to get file size")}).len().to_usize().unwrap(); - if size > GUITAR_FILE_MAX_SIZE {panic!("File is too big (bigger than 16 MB)");} - let f = fs::OpenOptions::new().read(true).open(&args.input).unwrap_or_else(|_error| { - /*if error.kind() == fs::ErrorKind::NotFound {panic!("File {} was not found", &file);} - else if error.kind() == fs::ErrorKind::PermissionDenieds {panic!("File {} is unreadable, check permissions", &file);} - else {panic!("Unknown error while opening {}", &file);}*/ - panic!("Unknown error while opening {}", args.input); - }); - let mut data: Vec = Vec::with_capacity(size); - f.take(u64::from_ne_bytes(size.to_ne_bytes())).read_to_end(&mut data).unwrap_or_else(|_error|{panic!("Unable to read file contents");}); - let mut song: gp::Song = gp::Song::default(); + let args = Args::parse(); + let path = Path::new(&args.input); + + if !path.exists() { + eprintln!("Error: File '{}' not found.", args.input); + std::process::exit(1); + } + + let ext = path.extension() + .and_then(|e| e.to_str()) + .map(|e| e.to_uppercase()) + .unwrap_or_else(|| "UNKNOWN".to_string()); + + let size = fs::metadata(&args.input) + .map(|m| m.len() as usize) + .unwrap_or(0); + + if size > GUITAR_FILE_MAX_SIZE { + eprintln!("Error: File is too large (> 16MB)"); + std::process::exit(1); + } + + let mut file = fs::File::open(&args.input).expect("Cannot open file"); + let mut data = Vec::with_capacity(size); + file.read_to_end(&mut data).expect("Cannot read file"); + + let mut song = Song::default(); match ext.as_str() { "GP3" => song.read_gp3(&data), "GP4" => song.read_gp4(&data), "GP5" => song.read_gp5(&data), - "GPX" => println!("Guitar pro file (new version) is not supported yet"), //new Guitar Pro files - _ => panic!("Unable to process a {} file (GP1 and GP2 files are not supported)", ext), - } - println!("Artist: \"{}\"", song.artist); - println!("Title: \"{}\"", song.name); - println!("Album: \"{}\"", song.album); - println!("Author: \"{}\"", song.author); - println!("Date: \"{}\"", song.date); - println!("Copyright: \"{}\"", song.copyright); - println!("Writer: \"{}\"", song.writer); - println!("Transcriber: \"{}\"", song.transcriber); - println!("Comments: \"{}\"", song.comments); - let _out = song.write((3,0,0), Some(false)); + _ => { + eprintln!("Error: Unsupported format '{}'.

each `Beat` contains `Note`s +- Effects are split: `NoteEffect` (bend, slide, harmonic, grace) on notes, `BeatEffects` (stroke, chord, mix table) on beats + +**Module layout (`lib/src/`):** +- `model/` — All data structures (Song, Track, Measure, Beat, Note, effects, enums, chord, etc.) +- `io/` — Binary I/O primitives (`primitive.rs`), GPIF XML structures (`gpif.rs`), ZIP handling (`gpx.rs`) +- `audio/` — MIDI channel definitions and GM instrument names + +**Trait-based parsing API:** Functionality is organized into ~12 traits (e.g., `SongTrackOps`, `SongMeasureOps`, `SongNoteOps`, `SongEffectOps`, `SongChordOps`) implemented on `Song`. Each trait provides `read_*` and `write_*` methods for its domain. All traits are re-exported from `lib.rs`. + +**Binary parsing pattern:** All GP3/4/5 parsing uses a `(data: &[u8], seek: &mut usize)` cursor pattern. Low-level reads go through `io::primitive` functions (`read_byte`, `read_int`, `read_short`, `read_int_byte_size_string`, etc.). + +**Version branching:** `Song.version.number` is a `(u8, u8, u8)` tuple. Format-specific logic branches on this throughout the parsing code (e.g., GP5 has separate author field, different padding bytes). + +**GP7+ (.gp) parsing** uses a different path: ZIP extraction → XML deserialization via `serde`/`quick-xml` into `Gpif` structs → conversion to `Song` model. + +## Format Support + +- GP3, GP4, GP5: Full read support, partial write support +- GP7 (.gp): Initial read support via GPIF XML +- GP6 (.gpx): Not yet implemented +- Error handling currently uses `panic!()` — no `Result` types yet + +## File Structure Documentation + +Binary format specs are in `lib/FILE-STRUCTURE*.md` files — useful when modifying parsing logic. diff --git a/cli/src/main.rs b/cli/src/main.rs index 752af85..ad25f1b 100644 --- a/cli/src/main.rs +++ b/cli/src/main.rs @@ -1,6 +1,6 @@ use clap::Parser; -use scorelib::gp::Song; -use scorelib::track::Track; +use scorelib::Song; +use scorelib::Track; use std::path::Path; use std::fs; use std::io::Read; @@ -52,10 +52,7 @@ fn main() { "GP4" => song.read_gp4(&data), "GP5" => song.read_gp5(&data), "GP" => song.read_gp(&data), - "GPX" => { - eprintln!("Error: GPX format (Guitar Pro 6) is not yet implemented."); - std::process::exit(1); - } + "GPX" => song.read_gpx(&data), _ => { eprintln!("Error: Unsupported format '{}'.
