m42e / zsh-histdb-skim

A zsh histdb browser using skim. Implemented in rust.

zsh-histdb-skim

This is a reimplementation of https://github.com/m42e/zsh-histdb-fzf in rust and using skim as a library.

Why

zsh-histdb-fzf works, but it is a bit quirky. It has for sure some flaws, regarding responsiveness and communication with processes. skim offers a fzf like behavior and is available as library in rust. It lacks some highlighting in the header, and has a bit different order/matching algorithm.

This should result in better performance, responsiveness and a more stable behavior.

Why rust?

skim is available in rust. I have never tried rust with a purpose before. I wanted to give it a try and learn something new.

How it works

Well, it accesses the zsh histdb. It lets you search on different levels.

What do you have to do?

Install the plugin, e.g. using zplug.

  zplug 'm42e/zsh-histdb-skim', from:github, at:main

It downloads the binary (if available) automatically. You can do manually by calling histdb-skim-download. It will be saved in ${XDG_DATA_HOME}/zsh-histdb-skim, alternatively ${HOME}/.local/share/zsh-histdb-skim. You can specify the directory manually by setting HISTDB_SKIM_PATH.

The download will happen if the executable is not there or the version is outdated (starting from v0.7.0). These checks happen when sourcing the script.

The plugin calls bindkey but some other plugins may overwrite. In this case you would have to do it yourself:

bindkey '^R' histdb-skim-widget

Additional information

By default the binary is downloaded

Building

cargo build --release
mkdir -p bin
mv target/release/zsh-histdb-skim bin

TODO

• improve rust code

Apologies 😉

While I stole the idea from myself, this is my first rust project ever. So I would be glad for tips and improvement PRs.
