- Must use Python 3.3 or higher for proper character encoding support.
- Python2.7 (and maybe lower) versions work, but aren't officially supported (some special characters won't work etc).
- The master branch is considered stable.
- Tested on Unix.
No dependencies outside the Python Standard Library required.

Suplemon has various add-ons that implement extra features. The commands can be run with Ctrl + E and the prompt has autocomplete to make running them faster. The available commands and their descriptions are:
A simple autocompletion module.
This adds autocomplete support for the tab key. It uses a word list scanned from all open files for completions. By default it suggests the shortest possible match. If there are no matches, the tab action is run normally.
Simple module for adding docstring placeholders.
This module is intended to generate docstrings for Python functions. It adds placeholders for descriptions, arguments and return data. Function arguments are crudely parsed from the function definition and return statements are scanned from the function body.
Bulk delete lines and characters. Asks what direction to delete in by default.
Add 'up' to delete lines above highest cursor. Add 'down' to delete lines below lowest cursor. Add 'left' to delete characters to the left of all cursors. Add 'right' to delete characters to the right of all cursors.
Toggle line commenting based on current file syntax.
Shortcut for openning the config files.
Encrypt or decrypt the current buffer. Lets you provide a passphrase and optional salt for encryption. Uses AES for encryption and scrypt for key generation.
View a diff of the current file compared to it's on disk version.
Evaluate a python expression and show the result in the status bar.
If no expression is provided the current line(s) are evaluated and replaced with the evaluation result.
Shortcut to openning the keymap config file.
Linter for suplemon.
Transform current lines to lower case.
Trim whitespace from beginning of current lines.
Toggle paste mode (helpful when pasting over SSH if auto indent is enabled)
Reload all add-on modules.
Replace all occurrences in all files of given text with given replacement.
Reverse text on current line(s).
Trim whitespace from the end of lines.
Save the current file.
Save all currently open files. Asks for confirmation.
Sort current lines.
Sorts alphabetically by default. Add 'length' to sort by length. Add 'reverse' to reverse the sorting.
Trim whitespace from start and end of lines.
Convert tab characters to spaces in the entire file.
Toggle visually showing whitespace.
Transform current lines to upper case.

If you are interested in contributing to Suplemon, development dependencies can be installed via:
# For OS cleanliness, we recommend using `virtualenv` to prevent global contamination pip install -r requirements-dev.txt
After those are installed, tests can be run via:
PRs are very welcome and appreciated.
When making PRs make sure to set the target branch to
dev. I only push to master when releasing new versions.
For many the command line is a different environment for text editing. Most coders are familiar with GUI text editors and for many vi and emacs have a too steep learning curve. For them (like for me) nano was the weapon of choice. But nano feels clunky and it has its limitations. That's why I wrote my own editor with built in multi cursor support to fix the situation. Another reason is that developing Suplemon is simply fun to do.
