### Function usage (when sourced)
If the script is sourced from another installer script, call `github_release_installer` directly.
Use environment variables to set options, for example:
- `ASSET_TYPE='\.tar\.gz$'` to filter for tar.gz assets.
- `ASSET_NAME='gh_2.70.0_macOS_arm64.zip'` to pick an exact file.
- `TEST_MODE=1` to run without downloading/installing.
- `OUTPUT_DIR='/tmp'` to download only.
- `SYSTEM` and `ARCH` to override platform detection.
```bash
source "$(dirname "$0")/github-release-installer"
ASSET_TYPE='\.tar\.gz$'
github_release_installer "Databricks CLI" "databricks" "databricks/cli"
# Pick a specific asset by exact filename
ASSET_NAME='gh_2.70.0_macOS_arm64.zip'
github_release_installer "GitHub CLI" "gh" "cli/cli"
# Dry-run mode (no side effects)
TEST_MODE=1
github_release_installer "GitHub CLI" "gh" "cli/cli"
# Download only (no install)
OUTPUT_DIR='/tmp'
github_release_installer "GitHub CLI" "gh" "cli/cli"
# Override platform detection
SYSTEM='linux'
ARCH='x86_64'
github_release_installer "GitHub CLI" "gh" "cli/cli"
```
