hsh

~~Don't use this, it's not ready!~~You probably don't want to use this yet, but it's my current default shell (whatcould go wrong) so it might work for you if you're brave enough.

Current technological breakthrough => "counting"

Hash is a slightly different take on your shell. It's closer to a user agentthan you standard POSIX shell. It's less of an instance, of a shell, and muchcloser to a system shell. E.g. when you add an alias in one instance, it becomesavailable on all instances as well. Changing a setting in one, updates it acrossall[^ephem].

[^ephem]: There ~~is~~ will eventually be an ephemeral mode to allow any instance to have it's own settings without affecting your other shells on the system.

Goals

• Support *modern* pttys
• Composable vs decomposable mode
• Less than 1h to migrate from any $SHELL (still considering reverts as well)
• cd should not exec any payloads

[De]composable mode

A default, unconfigured install of hsh should enable all features and functionality. Running hsh non-interactive, or [other] should disable all helful, or context aware features unless explicitly enabled.

Requirements

Compilation requires zig 0.12.0 or greater.

Install

git clone https://srctree.gr.ht/repo/hsh<br>zig build<br>./zig-out/bin/hsh

or zig build -p /usr/ if you're brave enough to install into /usr/bin/hsh

Tests can be run with zig build test

notes

(zig build run does some magic that causes hsh to segv)
