ws_manager

A ws command for ROS 2 colcon workspaces. Build, clean, navigate, and inspect packages — without typing long paths or remembering colcon flags. Works with unsourced and uninstalled packages. No dependencies, pure bash.

TL;DR

ws build --all                    # build every detected workspace
ws build -w dev_ws -p my_pkg      # build one package in a specific workspace
ws cd my_package                  # jump to a package's source directory
ws cd --install my_package        # jump to its install prefix instead
ws clean -w dev_ws -p my_pkg      # wipe build/install/log for a package
ws list -p                        # list all workspaces + packages + install status
ws open my_pkg                    # open package in VS Code (configurable)
ws which my_pkg my_launch.py      # show source & install paths for a launch file
ws config set-build-args --symlink-install --continue-on-error
ws doctor                         # diagnose PATH, ROS env, colcon, config
ws update                         # git pull + reinstall in one command

Workspaces are auto-detected from ROS_PACKAGE_PATH / COLCON_PREFIX_PATH. Fallback paths are configurable via WS_DEFAULT_WORKSPACES in ws_config.bash. Tab completion works everywhere.

Installation

git clone https://github.com/comrob/crl_ws_manager.git
cd crl_ws_manager
./install.sh
source ~/.bashrc

install.sh:

Symlinks all bin/ scripts into ~/.local/bin/ as ws, ws-build, etc.
Symlinks completion/ws_manager.bash into ~/.config/crl_ws_manager/
Symlinks lib/ws_lib.sh into ~/.config/crl_ws_manager/ for the sourced shell functions
Creates ~/.config/crl_ws_manager/ws_config.bash with defaults (if absent)
Adds ~/.local/bin to PATH in ~/.bashrc if missing
Adds a source block to ~/.bashrc to load shell functions on login
Also configures ~/.zshrc if your login shell is zsh

To uninstall, run ./install.sh --uninstall.

Commands

`ws build`

ws build [--all] [-w|--ws <workspace>]... [-p|--packages <pkg>]...

Flag	Description
`-w / --ws`	Workspace root (name relative to `$HOME`, or absolute path); repeatable
`-p / --packages`	Package name passed to `--packages-select`; repeatable
`--all`	Build all detected workspaces
`--clean`	Wipe package artifacts before building

ws build --all
ws build -w ros2_ws
ws build -w ros2_ws -p my_package
ws build -w ~/ros2_ws -p pkg_a -p pkg_b

Build flags are configured in ~/.config/crl_ws_manager/ws_config.bash.

`ws cd`

Changes directory to a package's source tree or install prefix.

ws cd [--source|--install] [-s|--include-system] <package_name>

Flag	Description
`--source`	Navigate to source directory in workspace `src/` (default)
`--install / -i`	Navigate to the install prefix
`-s / --include-system`	Completion also includes system packages from `ros2 pkg list`

roscd is an alias for ws cd.

ws cd liorf_slam_crl
ws cd --install liorf_slam_crl
ws cd -s <TAB>      # completes with local + system packages

`ws list`

ws list [-p|--packages] [-w|--ws <workspace>] [--installed] [-q|--quiet]

Lists detected workspaces; with -p also shows packages and install status.

`ws open`

ws open [--source|--install] <package_name>

Opens the package path in the configured editor. Configure via:

ws config set-editor code --reuse-window

Config keys: WS_EDITOR_PROGRAM (default code), WS_EDITOR_ARGS (default empty).

`ws which`

ws which <package_name> [launchfile]
ws which <package_name> --launch <launchfile>

Shows source path, install prefix, and (optionally) launch file paths — including whether the installed launch file is a symlink and whether it resolves to the same file as the source.

`ws clean`

ws clean [--clean-all] [-w|--ws <workspace>]... [-p|--packages <pkg>]... [<pkg>...]

Removes build/, install/, and log/ artifacts for selected packages or entire workspaces.

`ws config`

ws config [show|path|init|edit|set-editor|set-build-program|set-build-subcommand|set-build-args|require-all]

ws config show
ws config edit
ws config set-editor code --reuse-window
ws config set-build-args --symlink-install --continue-on-error
ws config require-all true

To configure fallback workspaces:

# In ~/.config/crl_ws_manager/ws_config.bash:
WS_DEFAULT_WORKSPACES=(
  "$HOME/ros2_ws"
  "$HOME/dev_ws"
)

See examples/ws_config.bash for a fully annotated template.

`ws doctor`

ws doctor

Checks all prerequisites and reports any problems:

ws and all subcommand binaries on PATH
Config file present
Shell functions file present
ROS_DISTRO set
colcon available
At least one workspace detected

`ws update`

ws update

Runs git pull in the repository root and re-runs install.sh.
Requires the tool to have been installed from a git clone.

`ws version`

ws --version
ws version

Prints the installed version string from the VERSION file.

`ws-cd-resolve` (scripting)

Lower-level executable used by the ws cd shell function. Prints the resolved path to stdout — useful in scripts.

ws-cd-resolve my_package          # prints source dir
ws-cd-resolve --install my_pkg    # prints install prefix

Bash Completion

Registered automatically when ~/.config/crl_ws_manager/ws_manager.bash is sourced.

Context	Completes
`ws <TAB>`	`build`, `clean`, `cd`, `list`, `open`, `config`, `help`
`ws build -p <TAB>`	Package names from active workspace `src/` directories
`ws build -w <TAB>`	Detected workspace names or path completion
`ws cd <TAB>`	Package names from active workspace `src/` directories
`ws cd -s <TAB>`	Package names including system packages (`ros2 pkg list`)
`ws open <TAB>`	Package names from active workspace `src/` directories
`ws which <TAB>`	Package names from active workspace `src/` directories
`ws which <pkg> <TAB>`	Installed launch files for `<pkg>`

Workspaces are detected dynamically — no paths are hardcoded. Completion does not require the workspace or package to be sourced or installed.

Running Tests

To run the full Bats test suite:

make test

The Bats suite is split into one file per command under tests/bats/:

File	Command	What it covers
`ws_manager_cmd.bats`	`ws` main dispatcher	`--version`, `cd --help`, shell wrapper delegation
`ws_build_cmd.bats`	`ws build`	help output, duplicate package → both workspaces built
`ws_clean_cmd.bats`	`ws clean`	help output, duplicate package → both workspaces cleaned
`ws_cd_resolve_cmd.bats`	`ws cd` / `ws-cd-resolve`	source/install resolution, symlink source, duplicate package order
`ws_list_cmd.bats`	`ws list`	quiet-mode symlink metadata, `--installed` filter
`ws_open_cmd.bats`	`ws open`	symlink source path, not-installed error, launch artifact
`ws_config_cmd.bats`	`ws config`	idempotent set-build-program, set-editor with args
`ws_which_cmd.bats`	`ws which`	machine-mode symlink metadata, launch completion fallback

A shared helper (tests/bats/test_helper.bash) provides make_pkg, make_pkg_at, and set_test_editor_echo used across suites.

Local CI Run

For quick local validation (same flow as CI):

make ci-local

ci-local runs in an isolated fixture root under /tmp/ws_manager_ci_local and uses a temporary HOME inside that root. You can override this root with:

WS_CI_TMP_ROOT=/tmp/my_ws_ci_fixture make ci-local

This runs:

shell syntax checks
install smoke
command smoke (ws --version, ws build --help, ws-cd-resolve --help, ws doctor)
Bats tests
uninstall smoke

ROS Distro Compatibility

Works with any installed ROS 2 distro (Humble, Iron, Jazzy, Kilted, Rolling, etc.). The tool reads $ROS_DISTRO at runtime — no distro-specific configuration is required or assumed. ws build sources /opt/ros/$ROS_DISTRO/setup.bash when that file exists and ROS_DISTRO is set; all other commands (ws cd, ws list, ws which, ws open, ws config) work without any ROS environment sourced.
