tmux-backup 0.5.15

#![warn(missing_docs)]

//! A backup & restore solution for Tmux sessions.
//!
//! Version requirement: _rustc 1.88+_
//!
//! ## Features
//!
//! - Backup and restore of your tmux environment:
//!   - tmux sessions windows, panes, with layout, titles & pane history
//!   - current and last session.
//! - Fast: less than 1 sec for 16 sessions, 45 windows and 80 panes.
//! - Show the catalog of backups, with age, file size, content description & archive format
//! - 2 strategies are available:
//!   - keep the `n` most recent backups
//!   - classic backup strategy:
//!     - the lastest backup per hour for the past 24 hours (max 23 backups - exclude the past hour),
//!     - the lastest backup per day for the past 7 days (max 6 backups - exclude the past 24 hours),
//!     - the lastest backup per week of the past 4 weeks (max 3 backups - exclude the past week),
//!     - the lastest backup per month of this year (max 11 backups - exclude the past month).
//! - Because you decide where backups are stored, you can use both strategies, combining the
//!   benefits of high-frequency backups and on demand backups like in tmux-resurrect.
//!
//! ## Getting started
//!
//! After installation (see below), you can either use it from the command line, or via tmux
//! bindings.
//!
//! The catalog is located by default in `$XDG_STATE_HOME/tmux-backup/`, or
//! `§HOME/.state/tmux-backup` otherwise. The default strategy is "most-recent", but you can change
//! it with `--strategy classic`. Check usage with `tmux-backup --help` for detailed help.
//!
//! ### View the catalog of existing backups
//!
//! ```console
//! $ tmux-backup catalog list --details
//! Strategy: KeepMostRecent: 10
//! Location: `$HOME/.local/state/tmux-backup`
//!
//!      NAME                             AGE         STATUS       FILESIZE    VERSION  CONTENT
//!  11. backup-20220907T224553.156103.tar.zst   2 days      purgeable    644.17 kB   1.0      16 sessions 43 windows 79 panes

//!   7. backup-20220909T225158.305403.tar.zst   18 hours    retainable   600.32 kB   1.0      16 sessions 42 windows 79 panes
//!   6. backup-20220910T152551.807672.tar.zst   1 hour      retainable   608.79 kB   1.0      16 sessions 43 windows 80 panes
//!   5. backup-20220910T165118.250800.tar.zst   29 minutes  retainable   614.16 kB   1.0      16 sessions 43 windows 80 panes

//!   3. backup-20220910T172016.924711.tar.zst   11 seconds  retainable   614.44 kB   1.0      16 sessions 43 windows 80 panes
//!   2. backup-20220910T172019.320809.tar.zst   8 seconds   retainable   614.42 kB   1.0      16 sessions 43 windows 80 panes
//!   1. backup-20220910T172024.141993.tar.zst   3 seconds   retainable   614.38 kB   1.0      16 sessions 43 windows 80 panes
//!
//! 11 backups: 10 retainable, 1 purgeable
//! ```
//!
//! If you installed the plugin config into tmux, then the default tmux bindings for listing
//! backups are
//!
//! - `prefix + b + l` to show the simple catalog
//! - `prefix + b + L` to show the detailed catalog (adds the filesize, version & content columns)
//!
//! Both of these bindings will open a tmux popup showing the catalog content.
//!
//! ### Save the current tmux environment
//!
//! ```console
//! $ tmux-backup save
//! ✅ 16 sessions 43 windows 80 panes, persisted to `/Users/graelo/.local/state/tmux-backup/backup-20220910T171812.893389.tar.zst`
//! ```
//!
//! By default, the tmux binding for saving a new backup are
//!
//! - `prefix + b + s` save and compact (delete purgeable backups)
//! - `prefix + b + b` save but not compact the catalog
//!
//! Both of these bindings will print the same report as above in the tmux status bar.
//!
//! ### Restore from a backup
//!
//! Typing `tmux-backup restore` in your shell outside of tmux will
//!
//! - start a tmux server if none is running
//! - restore all sessions from the latest backup
//! - but you still have to `tmux attach -t <your-last-session>`
//!
//! The same command typed in a shell inside tmux will erase session `0` (the default start
//! session) and restore your tmux environment in place.
//!
//! By default, the tmux binding for restoring the latest backup is
//!
//! - `prefix + b + r` restore sessions from the latest backup
//!
//! ## Installation
//!
//! ### Installing the binary
//!
//! On macOS
//!
//! ```shell
//! brew install graelo/homebrew-tap/tmux-backup  # will also install shell completions
//! ```
//!
//! On linux
//!
//! ```shell
//! curl \
//!     https://github.com/graelo/tmux-backup/releases/download/v0.4.0/tmux-backup-x86_64-unknown-linux-gnu.tar.xz \
//!     | tar xf - > /usr/local/bin/tmux-backup
//! chmod +x /usr/local/bin/tmux-backup
//! ```
//!
//! On linux, to install completions, type
//!
//! ```shell
//! tmux-backup generate-completion zsh|bash|fish > /path/to/your/completions/folder
//! ```
//!
//! ### Installing the tmux plugin hook
//!
//! Type
//!
//! ```shell
//! mkdir ~/.tmux/plugins/tmux-backup
//! tmux-backup init > ~/.tmux/plugins/tmux-backup/tmux-backup.tmux
//! ```
//!
//! If you don't use [tpm](https://github.com/tmux-plugins/tpm), just add this to your
//! `.tmux.conf`:
//!
//! ```text
//! source-file ~/.tmux/plugins/tmux-backup/tmux-backup.tmux
//! ```
//!
//! Alternatively, if you use tpm, declare the tmux-backup plugin to TPM in your `~/.tmux.conf`:
//!
//! ```tmux
//! set -g @tpm_plugins '              \
//!   tmux-plugins/tpm                 \
//!   tmux-plugins/tmux-backup         \  <-- here
//!   tmux-plugins/tmux-copyrat        \
//!   tmux-plugins/tmux-yank           \
//!   tmux-plugins/tmux-resurrect      \
//!   tmux-plugins/tmux-sessionist     \
//! '
//! ```
//!
//! The next time you start tmux, the `tmux-backup.tmux` configuration will be loaded.
//!
//! ## Caveats
//!
//! - This is a beta version
//! - Does not handle multiple clients: help is welcome if you have clear scenarios for this.
