Description

Sorry about it being so large, this pr should be MUCH EASIER to review commit by commit

Features:

• adds a plugin settings screen
• preprocessor fold regions
  • can optionally collapse inactive regions by default (based on preprocessor condition checks)
  • can optionally collapse all by default
• preprocessor condition checking
  • now support chained checks e.g. //#if this && that
  • now support loader checks e.g. //#if FABRIC && !FORGE
  • now correctly checks conditions that need to be false, such as the #if/elseif's preceding an #else/elseif block being tested
• preprocessor jump to file action
  • now also correctly moves you to the same caret position and scrolls to it
  • can now differentiate files based on the preprocessor conditions that apply at the caret position
  • can now optionally hide those differentiated results
  • can now press the down arrow from the search bar to navigate to the list (keyboard navigation streamlining)
• can optionally highlight formatting/clarity problems such as:
  • #if directive not being indented further than it's containing preprocessor block
  • #else/elseif/endif directives not having a matching indent with their initial #if directive
• adds an option to disable the //$$ insertion on new lines

Fixes:

• fixed kotlin k2 mode not registering correctly and always ignoring the optional kotlin-plugin.xml, and thus no working kotlin file folding in k2
• the condition changes fixed/improved PreprocessorNewLineHandler noticably
• several bugs from the previous preprocessor condition checking, including the prevSibling iterating not correctly finding previous directives
• correct version checking has replaced some logic that used mainVersion for all files, mainVersion is still a fallback if this fails

Fixes #22
Fixes #20 but not the side note
Fixes #18
Fixes #15 to an extent

How to test

automatic default folding based on file version
in 1.12.2 version file

settings screen with default settings

differentiate jump to files based on conditions applied at caret

same but with non matches hidden

format highlighting

other changes arent really showable via screenshot, will require actual testing with k2 kotlin mode && various preprocessor conditions that didnt work before such as //#if MC>11600 && !FABRIC
