What is this for?
A good IDE should support this in my opinion. With this plugin you can define a format
you can rename(Shift + F6), find usages of (Alt + F7) or Go To (CTRL + Click).
By default all strings in format ':hyphen-identifier' are symbols but you can configure
recognized formats in the plugin configuration page.
How to install it
You can find this plugin on IntelliJ plugin repository.
Take a look at IntelliJ IDEA documentation
for instructions about installing plugins.
After installing, this plugin will recognize 'symbols' and will highlight them blue:
Symbols which appear only once in whole project are marked with warning:
Referenced symbols are shown without warning:
Symbol names will appear in the suggestions list (Ctrl + Space Bar):
You can easily find usages of symbol with Alt + F7:
Even more conveniently you can go to usage with Ctrl + left click:
Last but not least you can rename your symbol with Shift + F6:
This plugin is definitely not finished. If you've found it useful feel free to contribute.
