# plane-cli — a lightweight zsh + curl CLI for Plane (https://plane.so).
# Works with any Plane instance (cloud or self-hosted). Nothing instance-specific
# is hard-coded: state maps are fetched live and the active project is remembered.
#
# Source this file from your ~/.zshrc:   source /path/to/plane.zsh
#
# Required env:
#   PLANE_API_KEY   your Plane API token   (Plane: Settings -> API tokens)
#   PLANE_BASE      https://<host>/api/v1/workspaces/<workspace-slug>
# Optional env:
#   PLANE_PROJECT          pin the active project (UUID); otherwise use `pluse`
#   PLANE_PROJECT_NAME     display name for the pinned project
#   PLANE_EVERYTHING_PROJECT / PLANE_EVERYTHING_NAME   target for `plsync`
#   PLANE_CLI_HOME         config dir (default: ${XDG_CONFIG_HOME:-~/.config}/plane-cli)
# Deps: zsh, curl, python3, fzf
