Copier update: install task from uv - #109
Merged
Merged
Conversation
Task is now installed with `uv tool install go-task-bin==3.53.1` instead of from its own GitHub release. One uv call replaces the hand-rolled per-OS install (PowerShell Invoke-WebRequest plus Expand-Archive on Windows, the taskfile.dev install script on POSIX) and covers Windows, macOS and Linux on both x86_64 and arm64, so shlex is no longer needed. Note that this trades a first-party source, where the installer verified the pinned tag against Task's published checksums, for a third-party repackaging of the upstream release archives on PyPI. The version stays pinned and uv records the wheel hash in its tool receipt. The uv bootstrap moves out of the --no-python branch into its own install_uv and now always runs, because installing Task depends on it. `uv tool list` moves after install_task so Task appears in the listing.

Pin the uv and tool executable directories. uv_env inherits UV_INSTALL_DIR, UV_UNMANAGED_INSTALL, UV_TOOL_BIN_DIR, XDG_BIN_HOME, and related variables. These variables can place uv or the Task executable outside LOCAL_BIN_DIR.
On Windows, later calls use LOCAL_BIN_DIR / "uv". On both Windows and POSIX, install_task validates LOCAL_BIN_DIR / "task(.exe)". These calls can fail when an inherited variable selects another directory. POSIX invokes uv by name, so the uv call can fail when the selected install directory is not on PATH.
In both installer variants, remove UV_UNMANAGED_INSTALL from uv_env, then set the explicit directories:
uv_env.pop("UV_UNMANAGED_INSTALL", None)
uv_env.update(
{
"UV_INSTALL_DIR": str(LOCAL_BIN_DIR),
"UV_TOOL_BIN_DIR": str(LOCAL_BIN_DIR),
}
)XDG_BIN_HOME and related fallback variables do not need separate normalization when these explicit settings are present.

Handle the Task installer migration. An environment upgraded from the previous installer can retain an unmanaged task executable at the target path. uv 0.12.15 rejects that existing executable unless --force is set, so the check=True installation call can stop before the Task version check.
Add --force to both uv tool install commands:
