## プロジェクトの歴史と使われ方

Todo.txt CLI is the canonical shell implementation of the todo.txt method: tasks live in a plain text file and the todo.sh command edits, lists, prioritizes, completes, and archives those lines. The project is unusually durable for a CLI productivity tool because its data model is intentionally simple and portable.

### プロジェクトの歴史

The official changelog starts with 1.0.0 on 2006-05-11, described as a consolidated master script with usage notes. During 2006 the CLI added path handling, case-insensitive listing, priorities, completion dates, color options, a separated config file, aliases, interactive editing, and task archiving behavior.

The 2009 2.0 series expanded todo.sh beyond a single todo.txt file by adding commands for moving tasks, listing contexts and projects, appending to other files in the todo directory, and auto-archiving completed tasks. Version 2.1.0 added pluggability through a ~/.todo.actions.d directory and a more Unix-style ~/.todo.cfg fallback.

Later releases show a long maintenance arc rather than a rewrite. The 2011 release improved portability for Dropbox or USB-key workflows; 2013 added global /etc/todo/config support and a make install path; 2018 added XDG config/action locations and a code of conduct; 2020 added macOS Catalina support and minimal default filenames; 2024 released v2.13.0 with more priority/list behavior and safer custom-action checks.

### 採用の歴史

The README documents installation by Homebrew on macOS, make install on Linux, and Arch AUR packaging. It also points users to GitHub Discussions, Issues, Gitter, Reddit, and official social channels, which reflects a long-lived community around both the CLI and the broader todo.txt philosophy.

Todo.txt's adoption has been helped by the fact that its core storage is plain text. The README explicitly mentions common customizations such as moving the todo directory into a cloud drive, modifying colors, highlighting projects and contexts, and using a configuration template even when a global config is installed.

### 使われ方

Users run todo.sh with actions such as add, list, listall, listpri, listcon, listproj, do, archive, append, prepend, replace, and move. The official usage document emphasizes project and context notation, priority sorting, filtering by terms, add-ons, and keeping completed tasks in done.txt.

The package-manager usage pattern is simple: install the script, copy or create a ~/.todo.cfg, keep todo.txt, done.txt, and report.txt in a chosen directory, then bind aliases or shell completions around todo.sh. That makes it easy to script, version, sync, or inspect with standard Unix tools.

### パッケージ好きにとっての重要性

Todo.txt CLI is a package-nerd touchstone because it reduces a productivity system to a Bash script, a small config file, and line-oriented data. It is attractive to people who prefer grep, sed, version control, Dropbox-style sync, shell aliases, and editor integration over opaque app databases.

The project also influenced other plaintext task tools and integrations. Its changelog and usage docs describe add-ons, custom actions, context/project conventions, and portable config behavior, all of which made it a natural target for downstream packages and small personal automation.
