# Recipe Validation Setup - Quick Start
2+
3+
Your mojo-toml repo now has local validation tools that match modular-community CI exactly.
4+
5+
## ✅ What's Been Added
6+
7+
1. **Validation Script** - `scripts/validate-recipe.sh`
8+
- Runs rattler-build validation locally
9+
- Same checks as modular-community CI
10+
- Fast feedback before PR submission
11+
12+
2. **GitHub Actions** - `.github/workflows/validate-recipe.yml`
13+
- Auto-validates on push/PR
14+
- Shows results in Actions tab
15+
16+
3. **recipe.yaml** - Root-level recipe file
17+
- Validated schema (tests:, documentation:, repository:)
18+
- Mojo 0.25.7 with context variables
19+
- Ready for modular-community submission
20+
21+
4. **Documentation** - `docs/RECIPE_VALIDATION.md`
22+
- Complete validation guide
23+
- Common error reference
24+
- Integration examples
25+
26+
## 🚀 Usage
27+
28+
### Validate Locally (Before Committing)
29+
30+
```bash
31+
cd /Users/mjboothaus/code/github/databooth/mojo-toml
32+
./scripts/validate-recipe.sh recipe.yaml
33+
```
34+
35+
**Expected output:**
36+
```
37+
✅ Recipe validation passed!
38+
Your recipe.yaml follows the modular-community schema.
39+
```
40+
41+
### Update Other Packages
42+
43+
Copy these files to your other packages:
44+
45+
```bash
46+
# For each of: mojo-yaml, mojo-dotenv, mojo-ini, mojo-asciichart
47+
cp scripts/validate-recipe.sh ../mojo-yaml/scripts/
48+
cp .github/workflows/validate-recipe.yml ../mojo-yaml/.github/workflows/
49+
cp docs/RECIPE_VALIDATION.md ../mojo-yaml/docs/
50+
51+
# Copy recipe from modular-community (already validated)
52+
cp /path/to/modular-community/recipes/mojo-yaml/recipe.yaml ../mojo-yaml/
53+
```
54+
55+
### Automated Validation
56+
57+
The GitHub Actions workflow runs automatically when `recipe.yaml` changes. View results at:
58+
`https://github.com/DataBooth/mojo-toml/actions`
59+
60+
## 📋 Integration Options
61+
62+
### Option 1: Pre-commit Hook (Recommended)
63+
64+
Add to `.pre-commit-config.yaml`:
65+
66+
```yaml
67+
- repo: local
68+
hooks:
69+
- id: validate-recipe
70+
name: Validate recipe.yaml
71+
entry: ./scripts/validate-recipe.sh
72+
language: system
73+
files: ^recipe\.yaml$
74+
pass_filenames: false
75+
```
76+
77+
Then: `pre-commit install`
78+
79+
### Option 2: Just Recipe
80+
81+
Add to `justfile`:
82+
83+
```just
84+
validate-recipe:
85+
./scripts/validate-recipe.sh recipe.yaml
86+
```
87+
88+
Usage: `just validate-recipe`
89+
90+
### Option 3: Pixi Task
91+
92+
Add to `pixi.toml`:
93+
94+
```toml
95+
[tasks]
96+
validate-recipe = "./scripts/validate-recipe.sh recipe.yaml"
97+
```
98+
99+
Usage: `pixi run validate-recipe`
100+
101+
## 🔄 Workflow
102+
103+
1. **Update recipe.yaml** - Make your changes
104+
2. **Validate locally** - `./scripts/validate-recipe.sh recipe.yaml`
105+
3. **Fix issues** - If validation fails
106+
4. **Commit** - Once validation passes
107+
5. **Submit PR** - To modular-community with confidence
108+
109+
## 🎯 Benefits
110+
111+
- ✅ **Catch errors early** - Before PR submission
112+
- ✅ **Faster iteration** - No waiting for CI
113+
- ✅ **Same validation** - Exact same tools as modular-community
114+
- ✅ **Automated checks** - GitHub Actions integration
115+
- ✅ **Clear feedback** - Helpful error messages
116+
117+
## 📚 More Info
118+
119+
See `docs/RECIPE_VALIDATION.md` for:
120+
- Complete setup instructions
121+
- Common schema errors reference
122+
- Troubleshooting guide
123+
- Advanced usage
124+

# Platform Builds - Cross-Platform Considerations
2+
3+
## Your Packages Are Platform-Agnostic ✅
4+
5+
All your mojo-* packages contain **pure Mojo source code** with no platform-specific dependencies. They will build and run on:
6+
- ✅ **Linux** (x86_64, ARM64)
7+
- ✅ **macOS** (Intel, Apple Silicon)
8+
- ✅ **Windows** (via WSL - Mojo's current Windows support)
9+
10+
## Local Validation vs CI Builds
11+
12+
### What You're Running Locally
13+
When you run `./scripts/validate-recipe.sh`, it performs:
14+
- **Schema validation** - Checks recipe.yaml structure
15+
- **Dependency resolution** - Verifies channels and requirements
16+
- **Render-only mode** - Doesn't actually compile/build
17+
18+
**Platform:** Runs on your Mac (ARM64)
19+
**Scope:** Validates recipe correctness, not platform compatibility
20+
21+
### What modular-community CI Runs
22+
The modular-community workflow (`.github/workflows/build-pr.yml`) builds on:
23+
- `ubuntu-latest` (Linux x86_64)
24+
- `macos-latest` (macOS ARM64)
25+
- `magic_arm64_8core` (Custom ARM64 runner)
26+
27+
**Platform:** All three
28+
**Scope:** Full compilation and testing on each platform
29+
30+
## Why Your Packages Are Cross-Platform
31+
32+
### 1. Pure Mojo Source
33+
Your packages ship **source code**, not binaries:
34+
```yaml
35+
build:
36+
script:
37+
- mkdir -p $PREFIX/lib/mojo/toml
38+
- cp -r src/toml/* $PREFIX/lib/mojo/toml/ # Just copying .mojo files
39+
```
40+
41+
No compilation happens during installation - just file copying.
42+
43+
### 2. No Platform-Specific Code
44+
None of your packages use:
45+
- ❌ C/C++ extensions
46+
- ❌ Platform-specific syscalls
47+
- ❌ Architecture-dependent libraries
48+
- ❌ Binary dependencies
49+
50+
They're pure Mojo parsing/formatting libraries.
51+
52+
### 3. Mojo Compiler Handles Platforms
53+
The `mojo-compiler` dependency is platform-aware:
54+
```yaml
55+
requirements:
56+
run:
57+
- ${{ pin_compatible('mojo-compiler') }}
58+
```
59+
60+
When users install your package, conda fetches the appropriate `mojo-compiler` for their platform automatically.
61+
62+
## noarch Packages
63+
64+
Some of your packages (like mojo-dotenv) are marked as `noarch`:
65+
```yaml
66+
build:
67+
noarch: generic
68+
```
69+
70+
**Meaning:**
71+
- Built once, works everywhere
72+
- No recompilation needed per platform
73+
- Faster installation
74+
- Smaller storage footprint
75+
76+
**When to use `noarch`:**
77+
- ✅ Pure source files only (no compilation)
78+
- ✅ No platform-specific paths/tools
79+
- ✅ No test executables
80+
81+
**Your packages that could use `noarch`:**
82+
- mojo-toml ✅ (pure source)
83+
- mojo-yaml ✅ (pure source)
84+
- mojo-asciichart ✅ (pure source)
85+
- mojo-dotenv ✅ (already marked noarch)
86+
- mojo-ini ⚠️ (builds .mojopkg, platform-specific)
87+
88+
## Adding noarch to Your Recipes
89+
90+
To make packages truly platform-independent, add to your recipes:
91+
92+
```yaml
93+
build:
94+
number: 0
95+
noarch: generic # <-- Add this
96+
script:
97+
- mkdir -p $PREFIX/lib/mojo/package
98+
- cp -r src/package/* $PREFIX/lib/mojo/package/
99+
```
100+
101+
**Benefits:**
102+
- Single build works everywhere
103+
- Faster package creation
104+
- Less storage on conda servers
105+
106+
**Trade-off:**
107+
- Can't do platform-specific logic in build scripts
108+
- Can't compile binaries
109+
- (Not an issue for your pure-source packages)
110+
111+
## Testing Locally on Other Platforms
112+
113+
### Test on Linux (via Docker)
114+
```bash
115+
docker run -it --rm -v $(pwd):/workspace condaforge/miniforge3:latest bash
116+
cd /workspace
117+
./scripts/validate-recipe.sh recipe.yaml
118+
```
119+
120+
### Test on Linux (via GitHub Actions)
121+
The `.github/workflows/validate-recipe.yml` runs on `ubuntu-latest`, so pushing to GitHub tests Linux automatically.
122+
123+
### Windows Testing
124+
Mojo on Windows requires WSL2. For now, rely on:
125+
1. Local macOS validation (schema/syntax)
126+
2. CI Linux builds (prove cross-platform works)
127+
3. User testing on Windows once published
128+
129+
## Recommendation
130+
131+
For your next recipe updates, consider adding `noarch: generic` to:
132+
- ✅ mojo-toml
133+
- ✅ mojo-yaml
134+
- ✅ mojo-asciichart
135+
136+
Keep mojo-ini without `noarch` since it builds a `.mojopkg` file.
137+
138+
This will make builds faster and more efficient while maintaining full cross-platform compatibility.
139+
140+
## Summary
141+
142+
| Aspect | Status | Notes |
143+
|--------|--------|-------|
144+
| **Your code** | ✅ Platform-agnostic | Pure Mojo source |
145+
| **Local validation** | ✅ Works on your Mac | Schema + dependency checks |
146+
| **CI builds** | ✅ Multi-platform | Linux, macOS, ARM64 |
147+
| **User installs** | ✅ Any platform | Mojo compiler handles it |
148+
| **Recommendation** | Add `noarch: generic` | Faster, more efficient |
149+
150+
Your packages will work on any platform that supports Mojo! 🎉
