Jankily making relative line numbers in Vintage mode
VintageLines is available via Sublime Package Control. Now compatible with ST3!
If you prefer to always have relative line numbers on set the setting "vintage_lines.force_mode": true.
If you prefer a key binding toggle relative lines on and off you can set one up by using key binding code like the following:
{"keys": ["ctrl+t"], "command": "toggle_setting", "args": {"setting": "vintage_lines.force_mode"}}
Note that you should also set vintage_lines.force_mode in your User Preferences to your preferred default
for the toggle to be effective in both command mode and insert mode.
