rash, the rat ass shell, is a rudimentary shell written in C.

Features

While not as featureful as other shells, rash is still very usable.

Some of rash's current features include:

• Environment variable modification
• Shell variables
• Globbing (using wildcards to match files)
• Auto Completion
• Job management
• Storing command history
• Custom prompts
• ...and much more!

Getting Started

To build rash, take a look at the build guide.

Once you have built rash, feel free to take a look at the user guide.

Setting up clangd

To setup clangd for this project, you will need to generate a compile_commands.json file.

For this, I use Bear, but you can use other tools if you're more familiar with them.

make clean # make sure no build files exist so that bear knows how to compile all source files
bear -- make # this will generate a compile_commands.json in the root of the project

You can also specify make flags here, for example:

bear -- make ERROR_HELL=1 # this will generate a compile_commands.json with all errors enabled (not recommended for development)

For more if more info on make flags, check out the build guide.

Once you have a compile_commands.json file in the root of the project, clangd should work fine.
