In Unity you can set an external script editor instead of monodevelop from the menu Edit->Preferences->External Tools->External Script Editor.
External Script Args text box allows you to set the argument / parameters sent to the external program.
For sublime text I currently have “(File):(Line)”.
Where unity replaces (File)*** with the file name and ***(Line) with the line number before calling the external editor.
(Note Sublime Text allows for the “:” as a delimiter, with the syntax fileName:lineNumber:columnNumber .)
Is there a $(column) variable, or is there a list/documentation for these variables?
