rED

A simple and very limited vt100 text editor.

For a more modern editor, also written in Go, look into micro.

Features and limitations

• Has syntax highlighting for Go code.
• Can run gofmt.
• Can be used for drawing "ASCII graphics".
• The editor must be given a filename at start.
• The editor is always in "overwrite mode". Characters are never inserted so that other characters are moved around, except for ctrl-d for deleting a character.
• All trailing spaces are removed when saving, but a final newline is kept.
• Esc can be used to toggle "writing mode" where the cursor is limited to the end of lines and "ASCII drawing mode".
• Can handle text that contains the tab character (\t).
• Keys like Home and End are not even registered by the key handler (but ctrl-a and ctrl-e works).
• There is no undo.
• Expects utilities like gofmt to be in /usr/bin.

Known bugs

• Letters that are not a-z, A-Z or simple punctuation may not be possible to type in.
• Lines longer than the terminal width are not handled correctly.
• Characters may appear on the screen when keys are pressed. Clear them with ctrl-l.
• Unicode characters may not be displayed correctly when loading a file.

Hotkeys

• ctrl-q to quit
• ctrl-a go to start of line
• ctrl-e go to end of line
• ctrl-p scroll up 10 lines
• ctrl-n scroll down 10 lines
• ctrl-l to redraw the screen
• ctrl-k to delete characters to the end of the line
• ctrl-s to save (don't use this on files you care about!)
• ctrl-g to show cursor positions, current letter and word count
• ctrl-d to delete a single character
• ctrl-f to format the current file with go fmt (but not save the result).
• esc to toggle "text edit mode" and "ASCII graphics mode"
