|
||||
Create the `config` package with TOML loading, unknown-key validation, partial-merge semantics, and auto-discovery logic. This is the core of Phase 6 — all config behavior except CLI flag wiring.
|
||||
|
||||
Purpose: Implements CFG-01 (TOML override), CFG-02 (auto-discovery), CFG-04 (partial override), CFG-05 (unknown key error). The package exposes a single `Load(configPath string)` function that returns a ready-to-use `map[classify.TrafficClass]synth.FreqConfig`.
|
||||
|
||||
Output: `config/config.go`, `config/config_test.go`, updated `go.mod`/`go.sum`

<behavior>
|

- Test: Load(explicitPath) with valid TOML `[sounds.ICMP]\nfrequency = 100.0` returns map where ICMP.BaseHz == 100.0 and all other classes unchanged (CFG-01, CFG-04)

- Test: Load(explicitPath) with `[sounds.ICMP]\nfrequncy = 440` returns error containing "frequncy" (CFG-05)

- Test: Load("") in a directory with no netsynth.toml returns default ClassFreqConfigs map with no error (CFG-02)

- Test: Load(explicitPath) where file does not exist returns error containing "not found" (CFG-03 prep)
|

- Test: Load(explicitPath) with `[sounds.BOGUS]\nfrequency = 100.0` returns no error but stderr contains "unknown class" (D-09)
|

- Test: Load(explicitPath) with `[sounds.ICMP]\nfrequency = 100.0\nwaveform = "square"` returns ICMP with both overrides applied and harmonics regenerated
|

- Test: Load(explicitPath) with `[sounds.ICMP]\nwaveform = "invalid"` returns error containing "invalid waveform"

|

<implementation>
|
||||
Create `config/config.go` with:
|
||||
1. `SoundOverride` struct with pointer fields `Frequency *float64` and `Waveform *string` (toml tags)
|
||||
2. `rawConfig` struct with `Sounds map[string]SoundOverride` (toml tag "sounds")
|
||||
3. `Load(configPath string) (map[classify.TrafficClass]synth.FreqConfig, error)` — public entry point
|
||||
4. `resolvePath(configPath string) (path string, explicit bool, err error)` — handles D-05 discovery order
|
||||
5. `discoverPath() string` — probes ./netsynth.toml then ~/.config/netsynth/config.toml
|
||||
6. `parseFile(path string) (rawConfig, error)` — uses toml.DecodeFile + md.Undecoded() for CFG-05
|
||||
7. `validate(raw rawConfig) error` — validates waveform strings
|
||||
8. `merge(defaults map[classify.TrafficClass]synth.FreqConfig, overrides map[string]SoundOverride) map[classify.TrafficClass]synth.FreqConfig` — per-field overlay
|
||||
9. `copyDefaults() map[classify.TrafficClass]synth.FreqConfig` — shallow copy of ClassFreqConfigs
|
||||
10. `parseWaveform(s string) (synth.WaveformType, error)` — string-to-enum map
|
||||
11. `validWaveforms` map: "sine"->WaveformSine, "square"->WaveformSquare, "sawtooth"->WaveformSawtooth, "triangle"->WaveformTriangle
|
||||
|
||||
Add `github.com/BurntSushi/toml@v1.6.0` to go.mod via `go get`.
|
||||
|
||||
Per D-03: Per-field overlay merge — only non-nil pointer fields override defaults.
|
||||
Per D-07: Unknown keys detected via md.Undecoded(), error names the key.
|
||||
Per D-09: Unknown class names in [sounds.<name>] produce warning to stderr, not error.
|
||||
Per D-05: Discovery order: --config > ./netsynth.toml > ~/.config/netsynth/config.toml.
|
||||
Per D-06: Only one config file loaded, first found wins.
|
||||
Per D-08: Type mismatches produce clear error with field name.
|
||||
Per D-11: All validation happens before returning — fail fast.
|
||||
|
||||
When frequency is overridden and WaveformType != WaveformCustom, regenerate Harmonics via WaveformPresetHarmonics(cfg.WaveformType, newBaseHz, synth.SampleRate).
|
||||
When waveform is overridden, regenerate Harmonics via WaveformPresetHarmonics(newWt, cfg.BaseHz, synth.SampleRate).

|

|

</behavior>
|

<action>
|
||||
**RED phase:** Create `config/config_test.go` with all 9 test functions listed in behavior above. Each test:
|
||||
- Creates a temp TOML file with `os.CreateTemp(t.TempDir(), "*.toml")`
|
||||
- Calls `config.Load(tmpFile.Name())` (or `config.Load("")` for no-config test)
|
||||
- Asserts expected outcomes
|
||||
|
||||
For TestLoadNoConfig: use `t.Chdir(t.TempDir())` (Go 1.24 testing.T.Chdir) to ensure no netsynth.toml exists in working directory.
|
||||
|
||||
Create a minimal `config/config.go` with just `package config` and a stub `Load` function returning nil, nil so the test file compiles. Run `go test ./config/... -count=1` — all tests must FAIL (red).
|
||||
|
||||
**GREEN phase:** Implement `config/config.go` fully:
|
||||
|
||||
1. Run `go get github.com/BurntSushi/toml@v1.6.0` to add the dependency.
|
||||
|
||||
2. Package declaration and imports:
|
||||
```
|
||||
package config
|
||||
imports: errors, fmt, io/fs, os, path/filepath, strings
|
||||
github.com/BurntSushi/toml
|
||||
github.com/netsynth/netsynth/classify
|
||||
github.com/netsynth/netsynth/synth
|
||||
```
|
||||
|
||||
3. Types:
|
||||
- `SoundOverride` struct: `Frequency *float64 \`toml:"frequency"\``, `Waveform *string \`toml:"waveform"\``
|
||||
- `rawConfig` struct: `Sounds map[string]SoundOverride \`toml:"sounds"\``
|
||||
|
||||
4. `validWaveforms` var: map[string]synth.WaveformType with entries "sine"->WaveformSine, "square"->WaveformSquare, "sawtooth"->WaveformSawtooth, "triangle"->WaveformTriangle
|
||||
|
||||
5. `Load(configPath string) (map[classify.TrafficClass]synth.FreqConfig, error)`:
|
||||
- Call resolvePath(configPath) -> path, explicit, err
|
||||
- If err != nil, return nil, err
|
||||
- If path == "", return copyDefaults(), nil (CFG-02: silent default)
|
||||
- Call parseFile(path) -> raw, err
|
||||
- If err != nil AND explicit AND errors.Is(err, fs.ErrNotExist): return nil, fmt.Errorf("config file not found: %s", configPath)
|
||||
- If err != nil (other): return nil, err
|
||||
- Call validate(raw) -> err; if err, return nil, err
|
||||
- Return merge(copyDefaults(), raw.Sounds), nil
|
||||
|
||||
6. `resolvePath(configPath string) (string, bool, error)`:
|
||||
- If configPath != "": return configPath, true, nil
|
||||
- path := discoverPath()
|
||||
- return path, false, nil
|
||||
|
||||
7. `discoverPath() string`:
|
||||
- Check `os.Stat("netsynth.toml")` — if err == nil, return "netsynth.toml"
|
||||
- dir, err := os.UserConfigDir(); if err != nil, return ""
|
||||
- p := filepath.Join(dir, "netsynth", "config.toml")
|
||||
- Check os.Stat(p) — if err == nil, return p
|
||||
- return ""
|
||||
|
||||
8. `parseFile(path string) (rawConfig, error)`:
|
||||
- var raw rawConfig
|
||||
- md, err := toml.DecodeFile(path, &raw)
|
||||
- If err != nil, return raw, err (this handles file-not-found and parse errors including D-08 type mismatches)
|
||||
- undecoded := md.Undecoded()
|
||||
- If len(undecoded) > 0: keyPath := strings.Join(undecoded[0].String() ... ) — actually undecoded is []toml.Key where Key is []string. Use `undecoded[0].String()` which returns dot-joined path. Return raw, fmt.Errorf("config: unknown key %q — check spelling", undecoded[0].String())
|
||||
- Return raw, nil
|
||||
|
||||
9. `validate(raw rawConfig) error`:
|
||||
- For each className, override in raw.Sounds:
|
||||
- If override.Waveform != nil: call parseWaveform(*override.Waveform); if err, return err
|
||||
|
||||
10. `parseWaveform(s string) (synth.WaveformType, error)`:
|
||||
- If wt, ok := validWaveforms[s]; ok: return wt, nil
|
||||
- valid := []string{"sine", "square", "sawtooth", "triangle"}
|
||||
- Return 0, fmt.Errorf("config: invalid waveform %q — valid values: %s", s, strings.Join(valid, ", "))
|
||||
|
||||
11. `copyDefaults() map[classify.TrafficClass]synth.FreqConfig`:
|
||||
- result := make(map[...], len(synth.ClassFreqConfigs))
|
||||
- For k, v := range synth.ClassFreqConfigs: result[k] = v
|
||||
- Return result
|
||||
- Comment: "Shallow copy is safe because merge assigns fresh Harmonics slices from WaveformPresetHarmonics, never mutates the original."
|
||||
|
||||
12. `merge(defaults map[classify.TrafficClass]synth.FreqConfig, overrides map[string]SoundOverride) map[classify.TrafficClass]synth.FreqConfig`:
|
||||
- For className, override := range overrides:
|
||||
- class := classify.TrafficClass(className)
|
||||
- cfg, known := defaults[class]
|
||||
- If !known: fmt.Fprintf(os.Stderr, "Warning: config: unknown class %q (ignored)\n", className); continue (D-09)
|
||||
- If override.Frequency != nil:
|
||||
- cfg.BaseHz = *override.Frequency
|
||||
- If cfg.WaveformType != synth.WaveformCustom: cfg.Harmonics = synth.WaveformPresetHarmonics(cfg.WaveformType, cfg.BaseHz, synth.SampleRate)
|
||||
- If override.Waveform != nil:
|
||||
- wt, _ := parseWaveform(*override.Waveform) (already validated)
|
||||
- cfg.WaveformType = wt
|
||||
- cfg.Harmonics = synth.WaveformPresetHarmonics(wt, cfg.BaseHz, synth.SampleRate)
|
||||
- defaults[class] = cfg
|
||||
- Return defaults
|
||||
|
||||
Run `go test ./config/... -count=1` — all tests must PASS (green).
