the standalone shell
sheesh is a shell intended to be standalone, without extra libraries. Everything necessary for a shell should be included in the shell. From the input library (sheesh incorporates an independent and unique library) to the autocompletion.
sheesh is a shell that claims to be unique, with no third-party code. However, although this is hard work, interesting features are available, some of them are:
- Speed, simplicity and efficiency. The code is not perfect, but minimalist.
- Autocompletion, not only with tab, but also autocompletion while typing (autosuggestions).
- Configurable, while working on configuration files and new commands, you can temporarily modify the appearance of the prompt with the command of the same name, also, you are free to modify the source code, this is open source.
Looking to get involved in the project or just know what do sheesh need to improve? Here it is:
- Pipelines and other shell mechanisms.
- Resolve bugs, move the code to a cleaner format.
- Modify some code expressions, introducing clearer and more direct snippets.
- Comment and explain some parts of the code to make them clearer.
- I have found a bug when you press Control+C while inside a different process than the shell (it closes the forked process, but also the shell). I am investigating some solutions, which may be to change the behavior and handle the Control+C with an interesting C function.
- Eliminate calls to stty via system, and use termios.h instead.
More in the long term, it would be nice to add:
- Support for simple (sheesh-specific, as there are for Bash) scripts.
Note that, especially the input library, this program is in a fairly young state of development.
