# Habitat Usage Guide
Habitat is a dependency-sync tool for mono-repo-like layouts built from multiple Git repos and asset downloads. This skill provides setup guidance, copy-pastable config snippets, and a troubleshooting checklist for common sync failures.
## When to Apply
- Setting up a “main repo + dependency repos/assets” workspace using `.habitat` + `DEPS`
- Adding or changing dependency types: git repos, nested solutions, HTTP downloads, or custom actions
- Debugging `hab sync` failures related to config, auth, network, or integrity checks
## Troubleshooting Inputs
When sync fails (fetch errors, permission issues, timeouts), collect:
- Habitat version and distribution (`./hab` wrapper in repo, `hab.pex`, etc.)
- OS and architecture (darwin/windows/linux + arm64/x86_64)
- The exact command and full error output (do not paste any secrets)
- Relevant config snippets:
- `.habitat`
- `DEPS` (or the file pointed to by `deps_file` in `.habitat`)
## Installation and Versioning
Prefer committing the Habitat wrapper (`hab`) and config files (`.habitat`, `DEPS`) into the repository so developers and CI use the same version and configuration.
Avoid downloading `releases/latest` in automation, because it is not reproducible. Instead, pin to a specific release version (tag) and keep that pinned version consistent across developers and CI.
```bash
HABITAT_VERSION="0.3.145"
curl -L -o hab "https://github.com/lynx-family/habitat/releases/download/${HABITAT_VERSION}/hab"
chmod +x hab
```
If you just want to try Habitat locally (not recommended for CI), you can download the latest release:
```bash
curl -L -o hab "https://github.com/lynx-family/habitat/releases/latest/download/hab"
chmod +x hab
```
If you need integrity verification, pin an expected SHA-256 for `hab` in your repo/CI and verify after download:
```bash
EXPECTED_SHA256="<fill-me>"
if command -v shasum >/dev/null 2>&1; then
echo "${EXPECTED_SHA256} hab" | shasum -a 256 -c -
else
echo "${EXPECTED_SHA256} hab" | sha256sum -c -
fi
```
## Multi-Repo Setup (solutions + deps)
### 1) Generate `.habitat` (solution config)
Generate the Habitat config at the main repo root:
```bash
./hab config <repo remote uri>
```
`.habitat` describes one or more solutions. Minimal example:
```python
solutions = [
{
"name": ".",
"deps_file": "DEPS",
"url": "git@github.com:namespace/repo.git",
}
]
```
Fields:
- `name`: solution name, typically `"."` for the main repo
- `deps_file`: dependency manifest path (relative to the main repo root)
- `url`: the main repo remote URL (used by the tool/CI)
### 2) Write `DEPS` (dependency manifest)
In `DEPS`, define `deps = { ... }`. The key is the destination path in the main repo, and the value describes the dependency type and parameters.
#### 2.1 git deps (source repositories)
```python
deps = {
"lib/example": {
"type": "git",
"url": "git@github.com:namespace/lib.git",
"branch": "dev",
}
}
```
Notes:
- Prefer stable refs (e.g., commit) for reproducibility; use branches when you want rolling updates.
- If the destination directory already exists and contains local changes, decide whether overwriting is acceptable before syncing.
#### 2.2 solution deps (nested solutions)
If a dependency has its own dependency tree, you can bring it in as a solution and sync recursively:
```python
deps = {
"third_party/some_solution": {
"type": "solution",
"url": "git@github.com:namespace/solution_repo.git",
"branch": "main",
"deps_file": "DEPS",
}
}
```
#### 2.3 http deps (assets/archives/binaries)
Use this to download archives, toolchains, model files, etc. Prefer providing integrity checks for verifiability and reproducibility:
```python
deps = {
"third_party/tooling": {
"type": "http",
"url": "https://example.com/tooling.zip",
"sha256": "SHA256_HEX",
}
}
```
#### 2.4 action deps (custom sync actions)
Use this to run extra steps during sync (generate files, copy assets, apply patches, etc.). Example:
```python
def example_function():
from pathlib import Path
import shutil
dest_dir = Path("scripts/sync_something")
dest_dir.mkdir(parents=True, exist_ok=True)
src = dest_dir / "input.txt"
dst = dest_dir / "output.txt"
src.write_text("example\n", encoding="utf-8")
shutil.copyfile(src, dst)
deps = {
"scripts/sync_something": {
"type": "action",
"function": example_function,
}
}
```
## Sync Dependencies (hab sync)
Run at the main repo root:
```bash
./hab sync .
```
After sync, dependencies are materialized into the paths specified by the keys in `DEPS`.
## Track Config in Version Control
Commit the wrapper and config files to enable one-command bootstrapping for developers and CI:
```bash
git add hab .habitat DEPS && git commit -m "Add habitat to manage dependencies."
```
## FAQ / Common Failures
### 1) git permission/auth failures
Symptoms:
- Errors like `Permission denied`, `Authentication failed`, or `Could not read from remote repository`
Fix:
- Ensure the dependency `url` protocol matches your environment (SSH/HTTPS).
- For SSH, confirm your SSH key is configured and has access to the target repo.
- In CI, confirm the runner is provisioned with the right credentials.
### 2) http integrity check failures (sha256 mismatch)
Symptoms:
- Download succeeds but integrity verification fails
Fix:
- Check whether `url` content changed or redirects to different content.
- Recompute sha256 for the actual artifact and update `sha256` in `DEPS`.
- If the URL is rolling (e.g., “latest”), prefer an immutable, versioned URL.
### 3) Sync hangs/timeouts
Fix:
- Identify which dependency is slow (temporarily comment out others and bisect).
- Check proxy settings, DNS, and network reachability.
- For large git deps, consider pinning to a commit and reducing unnecessary history (if supported by your setup).
## Response Format (when assisting users)
When a user asks for help configuring deps, fixing errors, or speeding up sync, respond in this order:
1) Conclusion first (root cause + fix)
2) Minimal copy-pastable commands/snippets (`.habitat` / `DEPS` / `./hab sync .`)
3) Call out risky operations (overwriting local dirs, rolling deps harming reproducibility, etc.)
4) If it can still fail, list the next required inputs (version, full error log, relevant config snippets)
