Its README describes it as an enhancement to Taskwarrior rather than a standalone task manager. ### Project history The README and wiki say taskopen began as a simple wrapper script for Taskwarrior annotations and evolved into a customizable tool. The 2.0 planning wiki explains that the original monolithic Perl script had become hard to extend and that the rewrite aimed for a clearer CLI, clearer configuration, modular structure, and new use cases. The NEWS file records 1.x improvements around taskwarrior compatibility, arbitrary attributes/UDAs, helper scripts, TASKOPENRC, and taskopen 2.0.0 beta changes including a move from Perl to Nim, a new command-line interface, a new config syntax, label-based actions, and colored output. ### Adoption history The wiki records an AUR package as early as 2013. The source facts list Homebrew, Fedora/dnf, MacPorts, and Nix packages, showing the tool's spread through Taskwarrior-oriented Unix package channels. ### How it is used Typical usage is to annotate a Taskwarrior task with a file path, web link, URI, or a note marker, then run taskopen with a task ID or Taskwarrior filter. taskopen determines actionable annotations and can open one, present a menu, or batch-run matching actions. Configuration is central to taskopen's model. Official docs list TASKOPENRC, XDG config, ~/.config/taskopen/taskopenrc, and ~/.taskopenrc as lookup locations, and describe arbitrary regex-based actions and hooks. ### Why package nerds care taskopen is significant in CLI culture because it shows Taskwarrior's ecosystem style: small companion programs that compose with task annotations, shell commands, desktop openers, and text notes instead of adding everything to the core task binary. ### Timeline - 2013-02-25: Official wiki Packages page records an AUR package. - taskopen 1.0.1: Adds environment variables for customizable commands, Cygwin support, examples, auto-attaching annotations, and arbitrary Taskwarrior attributes/UDAs. - taskopen 1.1.5: Adds TASKOPENRC environment variable. - 2021-03-16: Official rewrite rationale page documents limitations of the monolithic Perl script. - 2021-03-26: Official 2.0 wiki page documents goals for the rewrite. - taskopen 2.0.0 beta: Moves from Perl to Nim and introduces a new CLI and config syntax. ### Related projects - Taskwarrior is the required base tool and taskopen's core integration point. - Alan Bowen's tasknote is named in the README as inspiration for default notes. ### Sources - - - - - - source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
