Remedying the pain of command line editing since 2014
Suplemon is a modern, slick and intuitive console text editor with multi cursor support. Suplemon replicates Sublime Text style functionality in the terminal with the ease of use of Nano. http://github.com/richrd/suplemon
Try it out! Installation is as easy as pulling the repo.
git clone https://github.com/richrd/suplemon.git
The master branch is considered stable.
No dependencies outside the Python Standard Library needed.
python3 cli.py [filename]...
Must use Python 3.3 for proper character encoding support.
Lower Python versions might work, but aren't officially supported.
Tested on Unix.
Suplemon is an intuitive command line text editor. It supports multiple cursors out of the box. It is as easy as nano, and has much of the power of Sublime Text. It also supports extensions to allow all kinds of customizations. To get more help use 'Ctrl + H' in the editor. Suplemon is licensed under the MIT license.

- Design proper API for plugins/extensions/macros

- Only confirm closing file if it's modified.
- Setup a IRC channel for Suplemon

- Lower/Upper/Reverse lettercase (todo: reverse case)
- Reverse line
- Regex find/search (make find configurable to do normal & regex)
- CSS highlighter
- Move the editor view (scroll) down when finding multiple occurances
- The following solved with global exit check (if any file is modified but not saved)
- Close files one at a time with 'save?' prompt.
- Prompt for close or exit confirmation only when file(s) have been modified
- Indicate if file was saved successfully or if it failed
- Better yes/no query for exit (and in general)
- Generic linelighter for generic highlighting

- List of recent files
- Setting for enabling/disabling undo for cursor changes
- Read only viewer
And disable editingDon't disable editing. Instead enable save as.
- Optimize rendering for ssh (minimal screen update)
- Only refresh cursors when moving around
- Only refresh modified lines when editing
- Display tab characters with a replacement char (tab messes up lines)
- Global clipboard (copy from one file to another)
- Extensions:
- Peer to peer colaborative editing. Could be implemented as an extension.
- Auto backup. Activate on n changes or every n seconds
- File selector, kind of like what nano has
- This should be implemented as an extension
- Could be triggered with a key binding (and/or override open file)
- Need to refactor App class to support views instead of just files
- A view could be an editor or an extension ui
- Extensions should be able to control both status bars and key legend
- Automatically add ; to end of lines
- Generalized: add line prepend and append commands
- Will need multiline comment and string detection etc.
- Input queries can't detect trailing whitespace
- Remember find query if occurance not found (jump to top of file)
- With multiple lines selected pressing backspace and enter makes changes (shouldn't)
- Unreliable undo/redo.
- Refine find and find_next commands.
- Don't forget string to find automatically when using Ctrl + F
- Finish refactoring viewer.py and editor.py
- Cut command fails when multiple cursors are on or close to the last line
- Fix 'finding' empty character. Revert to 'add_cursor_right'.
- Better auto find with ctrl+d. (Find the current word or character)
- Forget last find on esc.
- Return code 0 on exit: Curses forces code 130 and causes git to ignore saved commit message, argh!
-
Can't open files that have spaces in them.Works when using 'file\ name' - Config extension double loads config file, instead of switching to it
- Encoding errors
- Remove "Failed to load config." when file doesn't exist
- Delete key when cursor at line end;
add dedicated settingmade to work as normal. - Make adding cursors up and down smarter: add them at main cursor x coordinate if possible
- Saving file into a directory stores the relative path as the filename.
- Cursors sometimes left hanging at non existent coordinates (eg. when file reloaded) Solved by rectifying all cursors in move_cursors. Should optimize more in callers.
- Remove debug logging in non-debug mode
- Fill in incomplete config file with defaults
- Add 'remove previous cursor' function (fixed with undo/redo)
- Can't open files like '~/.suplemon-config.json'
- Cursor invisible when at end of scrolled line
- Esc key effect is delayed
- Fixed: Find starts at top of file instead of current
linecursor - Start find at current line AND column
- Make editor white color brighter (not gray)
- Show editor at top of terminal when show_top_bar == False
- Refactor main class to support views
- Editor
- Define core editing operations
- Make core editing operations overidable by extensions
- Line objects
- Add set_data method
- Add get_data method
- Cursor objects
- Methods for moving the cursor (left, right, up, down)
- Methods for getting cursor position
- Make cursor manipulation more functional
- Extensions
- Allow extensions to be run at a desired interval
- Implement events that can be hookend onto
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 learing 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.
