Use NEdit’s syntax highlighting to color columns in CSV (Comma-Separated Values) and TSV (Tab-Separated Values) files. Adapted from the (much more feature-reach) Vim plugin RainbowCSV.
- Download RainbowCSV.pats, and run
nedit -import path/to/RainbowCSV.pats - Optionally, go to NEdit menu bar, choose Preferences → Default Settings → Language Modes…, find the newly added language modes at the bottom of the list, and move them to the desired location using "Move ^" and "Move v" buttons (e.g. to arrange the language modes alphabetically)
- In NEdit menu bar, do Preferences → Save Defaults…
- Optionally, edit
~/.nedit/nedit.rcfile, find the sectionnedit.highlightPatterns, and move the newly added patterns to the desired location (e.g. to arrange the pattern definitions alphabetically). Note the "end of line" syntax for all lines except the last line of the section!
