Is it possible to display a right-margin line at 80 characters in TextMate? (i.e. the right-margin line in eclipse, gedit, etc.) If so, how can I configure that?
回答1:
Figured it out:
In the View menu, uncheck 'Soft Wrap'. Then, go to View -> Wrap Column -> Other... and select the column at 80 chars in your editor window.
This will show the line at 80 characters, but won't force wrapping at 80 chars. (Turning 'Soft Wrap' back on will force wrapping.)
回答2:
What about Visual Ornaments/Show right margin indicator in Preferences?
回答3:
For TextMate 2 it looks like this has moved to View -> Show Wrap Column.
So the column can be set at View -> Wrap Column, then shown/hidden using View -> Show/Hide Wrap Column.
