I use Sublime Text 2 and want a Ruler to be shown in every file with specific line-height. But I have to show it manually in every file.
Go to Sublime Text > Preferences > Settings - User
Add a "rulers"
setting with the lines you want for the ruler:
// Adds a single vertical ruler at column 80
"rulers": [80],
If you want multiple rulers, separate the values with a comma:
// Adds two vertical rulers: one at column 80 and one at column 120
"rulers": [80, 120],
Rulers not showing? Rulers are only shown when using a monospace font, which is the default font for Sublime Text. Ensure you are using a monospace font if the settings above don't work for you.
