Shsh Releases

A shell scripts handler (shsh) for managing shell scripts, functions, standalone binaries, completion files, and more.

What it does

Shsh allows you to quickly install shell packages directly from github or other sites. Instead of looking for specific install instructions for each package and messing with your $PATH, shsh will create a central location for all packages and manage their executable, completions files, and man files for you. It is multi-threaded to speed up updating and setting up your packages.

Shsh is a POSIX-compatible script handler, as a former fork of basher but was made to works with even the most strict POSIX compliance shell like dash. The performance of shsh is enhanced by using dash and with our use of multi-threaded approach. The flexibility of shsh comes from hooks where you can run arbitrary scripts that persists across package updates.

Quick Start

Automatic Installation

Automatically bootstrap and install shsh (which would also modify your shell's init script)

curl -s https://raw.githubusercontent.com/soraxas/shsh/master/bootstrap/install.sh | sh

Pre-made Recipes

shsh can retrive pre-made recipes hosted in my repo. For example:

shsh install -r mamba
shsh install -r git-annex

Custom Recipes

Ranger: A powerful terminal file manger

shsh install ranger/ranger -v REMOVE_EXTENSION=true -v BINS=ranger.py -h pre='sed -i "1d;2i#!/usr/bin/python3 -O" ranger.py'

Installation

  1. Manual: Checkout shsh inside $XDG_DATA_HOME, e.g., at ~/.local/share/shsh

     # clone shsh and add shsh to $PATH variable
     $ git clone https://github.com/soraxas/shsh ~/.local/share/shsh
     $ export PATH="$HOME/.local/share/shsh/bin:$PATH"
     # Optional: link shsh's own completion files and man pages to cellar
     $ cd ~/.local/share/shsh && make self-linking

    Or with AUR (Arch): Install shsh or shsh-git pacakage in AUR, e.g.

     $ yay -S shsh
  2. Initialise shsh in your shell init file, e.g.

     # in ~/.bashrc, ~/.zshrc, etc.
     eval "$(shsh init SHELL)"
     # SHELL: sh, bash, zsh, fish

    Fish: Use the following commands instead:

     $ shsh init fish | source

Updating

Run the following command to and pull the latest changes in shsh (Manual method only):

$ shsh self-upgrade

Usage

Examples

  • Installing remote packages

    $ shsh install sstephenson/bats

    By default, shsh will install package from Github. This will install bats and add bin/bats to $PATH.

    • Installing packages from other sites

      $ shsh install bitbucket.org/user/repo_name

      This will install repo_name from https://bitbucket.org/user/repo_name

    • Using ssh instead of https

      If you want to do local development on installed packages and you have ssh access to the site, use --ssh to override the protocol:

      $ shsh install --ssh juanibiapina/gg
  • Installing a local package

    $ shsh link directory my_namespace/my_package

    The link command allows you to directly link it to shsh (similar to pip install -e .) and any modification to your directory will have an immediate effect.

    • The link command will install the dependencies of the local package. You can prevent that with the --no-deps option:

      $ shsh link --no-deps directory my_namespace/my_package
  • Installing a github release directly (e.g. pre-compiled binary)

    $ shsh install --gh-release ajeetdsouza/zoxide FISH_COMPLETIONS=completions/zoxide.fish

    The --gh-release flag indicates that you want to directly download and link the binary within github release.

    • You can also pin a release version with:

      $ shsh install --gh-release junegunn/fzf@0.38.0

      which would download from releases with the 0.38.0 tag.

    • If shsh is unable to pick the correct asset for you (e.g., the release contains multiple files and it can't determines which to download), you can also specify the asset to download by

      $ shsh install vslavik/diff-pdf --gh-release=diff-pdf-0.5.tar.gz

      which would sort the asset by prioritising asset with the substring diff-pdf-0.5.tar.gz.

    NOTE: Downloading gh-release has an optional dependency on jq (to parse json). If your system does not has jq, shsh can also attempt to automatically bootstrap jq by itself.

  • Sourcing files from a package into current shell

    Basher provides an include function that allows sourcing files into the current shell. After installing a package, you can run:

    include username/repo lib/file.sh
    

    This will source a file lib/file.sh under the package username/repo.

Command summary

  • shsh install <package> - Installs a package from github, custom site, or any arbitrary recipes.
  • shsh uninstall <package> - Uninstall a package
  • shsh link <directory> - Installs a local directory as a shsh package
  • shsh help <command> - Display help for a command
  • shsh list - List installed packages
  • shsh outdated - List packages which are not in the latest version
  • shsh upgrade <package> - Upgrade a package to the latest version

Configuration options

To change the behavior of shsh, you can set the following variables either globally or before each command:

  • If $XDG_DATA_HOME is set, $SHSH_ROOT will be set as $XDG_DATA_HOME/shsh; if not set, $HOME/.local/share/shsh is the default. . It is used to store cellar for the cloned packages.
  • SHSH_FULL_CLONE=true - Clones the full repo history instead of only the last commit (useful for package development)
  • SHSH_PREFIX - set the installation and package checkout prefix (default is $SHSH_ROOT/cellar). Setting this to /usr/local, for example, will install binaries to /usr/local/bin, manpages to /usr/local/man, completions to /usr/local/completions, and clone packages to /usr/local/packages. This allows you to manage "global packages", distinct from individual user packages.

Packages handling

  • Packages are simply repos username/repo. You may also specify a site site/username/repo.

  • Any files inside a bin directory are added to $PATH. If there is no bin directory, any executable files in the package root are added to $PATH.

  • Any man pages (files ended in \.[0-9]) inside a man directory are added to the man path.

  • Optionally, a repo might contain a package.sh file which specifies binaries, dependencies and completions in the following format:

    BINS=folder/file1:folder/file2.sh
    DEPS=user1/repo1:user2/repo2
    BASH_COMPLETIONS=completions/package
    ZSH_COMPLETIONS=completions/_package

    BINS specified in this fashion have higher precedence then the inference rules above.

Recipes for installing packages (in shshrc)

The following are a list of recipes that uses shsh plus some lightweight hooks to bootstrap installing script/binaries on a new system. I personally has the following contents in my ~/.config/shshrc file.

I had defined some handy functions in the shshrc file:

has_cmd() {
  command -v "$1" >/dev/null
}
is_hostname() {
  [ $(cat /etc/hostname) = "$1" ]
}
is_wsl() {
  cat /proc/version | grep -q '[Mm]icrosoft'
}

Examples

  • The powerful delta for viewing diff or git-diff output:

    # if we have cargo, we can build delta directly
    has_cmd cargo && \
      shsh install dandavison/delta -h pre=make -v BINS=target/release/delta
  • High-level git workflow with git-town

    has_cmd go && \
        shsh install git-town/git-town -h pre='go build && ./git-town completions fish > git-town.fish' -v FISH_COMPLETIONS=git-town.fish
  • Install scripts only on some certain machine

    # for running bash tests
    is_hostname Arch && \
      shsh install bats-core/bats-core
  • Make sure files has executable bits in gist

    # for opening reverse port
    shsh install gist.github.com/soraxas/0ef22338ad01e470cd62595d2e5623dd soraxas/open-rev-ports -h a+x
  • Running post hook for wsl-open in wsl

    # script to simulate xdg-open in wsl
    is_wsl && \
      shsh install 4U6U57/wsl-open -h post='echo "*; wsl-open '"'"'%s'"'"'" > ~/.mailcap'
  • Scripts for installing pre-compiled binary for wsl

    is_wsl && \
      shsh install --plain wsl-tools/win32yank -v _ARCH=x64 -v _VERSION=v0.0.4 -h pre='curl -sLo out.zip https://github.com/equalsraf/win32yank/releases/download/$_VERSION/win32yank-$_ARCH.zip && unzip out.zip' -h +x=win32yank.exe
