Pipr

Pipr is a commandline pipe-building tool, written in Rust!

Pipr can automatically evaluate the pipeline you're editing in the background, showing you the results as you go. This makes writing complex sed and awk chains a lot easier, as you'll immediately see what they do.

Because this could be dangerous, (imagine typing rm ./*.txt to delete all text files, but it already being executed at rm ./*, deleting all files in your working directory), Pipr uses bubblewrap to execute your command in an isolated, read-only environment, making it safe to use. I wont give any guarantees, but you should be good :D.

To allow for even more efficiency, Pipr features a command history and a bookmark system, allowing you to quickly go back to previously worked on pipelines or look at how you did something before.

It also features a snippet-system, allowing you to define custom snippets that can be inserted with the press of a button. These can be used to insert common stuff like sed -r 's///g', even allowing you to specify where the cursor should be placed after inserting the snippet.

You can even look up documentation and help of your commands on the fly. Simply hover your cursor over the desired command and press F5. You can then choose between different documentation-options to look at. You can add your own options (for example tldr) in the config file in the [help_viewers] section.

Showcase

Installing

Using the static binary

If none of the listed installation-options are available to you, you can simply use the static binary provided on the releases page. This should work on most unix-based systems.

Arch Linux: Using the AUR

Pipr is available on the AUR, so you can simply install it using your favourite AUR-helper:

$ yay -S pipr-git

Using Cargo

If you have a Rust-setup and have cargo installed, you can install pipr using cargo:

$ cargo install pipr

Usage

Just start pipr!

Help is available in pipr by pressing F1.

Autoeval mode, propably the most important feature, can be toggled by pressing F2.

In the textfield, use Alt+Enter to insert a newline. These will be removed when evaluating, so you don't need to add any \es to the end of your lines.

Pipr will store it's history and bookmarks as well as a configuration file in ~/.config/pipr.

You can look at the default configuration by using pipr --config-reference. This will contain all available options, with some documentation added.

Terminal integration

In the shell_integration/ folder in this repository you'll find some scripts for different interactive shells. These allow you to call pipr from the terminal with a simple keypress, inserting your current line-buffer into pipr. If you're using fish, it will even put the final command back into your terminal's linebuffer after closing pipr.

To use these, simply put the lines from the respective file into your .bashrc or config.fish file.

Keymappings
Fish: Ctrl+Alt+a
Bash: Alt+a

Dependencies

Pipr uses bubblewrap to execute your command in an isolated environment, preventing most (but maybe not all, I won't give you any guarantees) dangers like accidentally deleting something while you're typing a command.

This means that you'll need to have bubblewrap somewhere on your PATH, or you'll have to use the unsafe-mode by passing the no-isolation flag.
