ergonomica / ergonomica

🖥️ a cross-platform modern shell.

Ergonomica

WARNING: master on this repository is not the same as a stable release! Currently, this software is purely experimental, as I am cleaning it up substantially after a long hiatus. However, if you find bugs, feel free to file an issue.

Ergonomica is a cross-platform shell language implemented in Python that aims to redesign the shell in a more standard, easy-to-use, and powerful way than traditional shells. It is designed as a fully-functional S-expression based language with a few traditional shell features such as flags and piping to combine the functionality of a Lisp with the convenience of the UNIX shell.

ergonomica's Issues

[Linux] - Requires one to run ergo_setup before first run.

Followed the installation instructions posted here and found that the documentation requires one more step to complete installation on Linux.

Might have to add this in your wiki installation page for linux:

---

Finally, configure ergonomica for first time use by:

ergo_setup.sh

---

btw - Nice project. Snappy suggestions 👍

Escape characters not displaying properly on Windows

The Issue

System Information

Windows 7, Python 2.7 (not sure of more information, this is a school computer).

Add `license` command documentation in wiki

ModuleNotFoundError: No module named 'prompt_toolkit.key_binding.bindings.utils'

There is no "utils" in "prompt_toolkit.key_binding.bindings".
When launching ergonomica in msys/Windows.

Windows support

CMD is awful. Python-based shell should be cross-platform.

Accidental newline (due to multiline prompt_toolkit input) causes an error

The Issue

Say I'm hacking away, and I decide to list what files are in my directory. I type $ ls
but then accidentally hit a newline, like so

$ ls

and hit meta-enter. Then I get

[ergo: CommandError]: No such command 'ls
'.
                      Did you mean ls?

Yikes!

Suplemon not cross-platform

after installation

Windows 10 bash - works well after linux way of installation. But the native support will be perfect.

Unhelpful Help

Explain how to use the different commands, and how the terminal works in general.

Formalize error handling

Right now, many commands simply print out "[ergo: ExceptionName]: ...." instead of actually raising an ErgonomicaError. Some even print that to stdout! As a result, handling such errors is inconsistent.

Ergonomica prompt changes color on first command

`readline` doesn't work in Windows

Let's face it, I can't code as well as Beazley.

Suplemon is executed a second time after quitting it

Hi, and many thanks for the awesome project! It caught me by total surprise when I noticed my editor (suplemon) was included. Background: I cloned master, installed the dependencies, and ran python3 ergonomica.py. Here's the bug I came across:

At first I just tried the edit command, but got this:

$ edit
[ergo: EditorError]: No such editor 'emacs'.

That's fine I thought and added EDITOR suplemon to my .ergo_profile. Then I tried the edit command again, and sure enough suplemon fired up, cool!

The bug: when I quit suplemon, the terminal flashed for a split second and suplemon was relaunched 😕 I quit it again, and it stayed closed. This doesn't happen when I use vim. Any idea what could be causing this? The return code for both vim and suplemon is 0.

clear command doesn't work

ergo - use /bin/sh instead of bash

Hello,

Is there any need to launch ergo from bash? /bin/bash isn't a portable path and this make ergonomica to depend on bash.

Using /bin/sh is portable and lighter.

Make Windows2Ergo parser

Currently, when some command is un-runnable in Ergonomica, it defaults to the system shell (only bash supported for now), and parses custom Ergonomica syntax down to that bash. There should be a parser that goes from Ergonomica to Windows (Powershell or BATCH) syntax.

Lonely (valid) operators returning OperatorError

The Issue

$ (filter)
