Adding Multiple Rulers

To add multiple rulers, edit the preferences file:

  1. Navigate to File > Open Preferences File.
  2. Add the following entries to the JSON configuration:
// existing json items
"editor.rulers": [40, 80],
"editor.rulerColors": ["green", "#f34d5a"],

These settings introduce two rulers at the 40th and 80th character positions, colored green and red respectively.

  2. editor.rulerColors : An optional array to set colors for each ruler, corresponding to the positions listed in editor.rulers.


Q: How do I add different rulers for each project?

To set up different rulers for individual projects, create a .phcode.json file in the root directory of each project. Include the same ruler configurations as shown in the example above.
