This change primarily focused on a revised +ssh-cache user interface,
but it also reworks a bunch of the internals.
The primary CLI improvement is support for positional arguments and a
consistent list output format that includes both the ISO-formatted
timestamp and relative age.
ghostty +ssh-cache # List all cached destinations
ghostty +ssh-cache user@example.com # Show that destination
ghostty +ssh-cache example.com # Show all users on that host
ghostty +ssh-cache --add=user@example.com # Manually add a destination
ghostty +ssh-cache --remove=user@example.com # Remove a destination
ghostty +ssh-cache --prune=30d # Remove entries older than 30 days
ghostty +ssh-cache --clear # Clear entire cache
Notable, we now support a --prune operation that replaces the previous
--expire-days flag that was never actually hooked up to anything (!!).
--prune also supports a wider range of Duration-based values.
We're also much more consistent with error codes: 0=success, 1=failure,
2=usage.
While working on those changes, I also reworked the cache internals,
particularly the code around timestamp handling and errors. For example,
I dropped the explicit error sets because they were growing unwieldy,
and in practice we only matched on a subset of those errors.
Lastly, overall test coverage should be much improved, especially around
the time- and allocation-related operations.
Subcommand Actions
This is the cli specific code. It contains cli actions and tui definitions and argument parsing.
This README is meant as developer documentation and not as user documentation. For user documentation, see the main README or ghostty.org.
Updating documentation
Each cli action is defined in it's own file. Documentation for each action is defined
in the doc comment associated with the run function. For example the run function
in list_keybinds.zig contains the help text for ghostty +list-keybinds.
