This plugin changes Idea font size if retina display is detected. If not detected, it changes font size back. I wrote it because I was tired to change font size, every time I plug external dispay

There is no configuration window, but you can change settings by editing 'fontsize/fontsize.properties' file in the jar. Default settings is hardcoded for Dell XPS 13 with retina resolution 3200x1200 and font size 22. For normal display it changes font size to 12.

Java Display API is mostly broken, so this plugin is hack, but it works on my system :-)

There is no reliable way to detect display DPI, so it uses display resolution to identify retina display. This plugin checks every 5 seconds if any of connected displays has retina resolution. Newly attached displays might not be detected, so make sure Idea starts with main display enabled.

TODO use xrandr to get list of displays on Linux.

Howto use this plugin

This plugin works in two scenarios:

• You change display resolution on your laptop screen on your battery. It works automatically.

• You plug external display with low DPI. In this case your main display must change resolution, or be disabled, for this plugin to detect change.

Problems

• Newly pluged displays might not be detected. Make sure that your main retina display is enabled when Idea starts

• Retina resolution is hardcoded to 3200x1200. You will have to edit fontsize/fontsize.properties
