Package Manager Script
This script provides the following commands:
install {identifier(s)|--all}
- Creates an executable bash wrapper in the bin folder that calls the command for the repository.
- Executes the repository’s "setup" command if specified.
pull {identifier(s)|--all}
- Executes 'git pull' in the repository directory.
clone {identifier(s)|--all}
- Clones the repository from a remote (using provider/account/repository or an alternative if 'replacement' is defined).
push {identifier(s)|--all}
- Executes 'git push' in the repository directory.
deinstall {identifier(s)|--all}
- Deletes the executable command/alias.
- Executes the repository’s "teardown" command if specified.
delete {identifier(s)|--all}
- Deletes the repository directory.
update {identifier(s)|--all|--system}
- Combines pull and install; if --system is specified also runs system update commands.
status {identifier(s)|--all|--system}
- Shows git status for each repository or, if --system is set, shows basic system update information.
config {identifier(s)|--all}
- Displays the configuration for one or more repositories. If no identifier is given, shows the entire config.
add
- Starts an interactive dialog to add a new repository configuration entry.
Additional flags:
--preview Only show the changes without executing commands.
--list When used with preview or status, only list affected repositories (for status).
Identifiers:
- If a repository’s name is unique then you can just use the repository name.
- If multiple repositories share the same name then use the full identifier in the form "provider/account/repository".
The configuration is read from a YAML file (default: config.yaml) with the following structure:
base: "/path/to/repositories"
repos:
- provider: "github.com"
account: "youraccount"
repository: "mytool"
verified: "commit-id"
command: "bash main.sh" # optional; if not set, the script checks for main.sh/main.py in the repository
description: "My tool description" # optional
replacement: "" # optional; alternative provider/account/repository string to use instead
setup: "echo Setting up..." # optional setup command executed during install
teardown: "echo Tearing down..." # optional command executed during deinstall
