6502-assembly-intellij

This version adds a code formatter for 6502 assembly files.

This release also corrects an issue where square brackets, as used in some 65C816 long addressing modes, were being treated as a syntax error.

Line markers for branch instructions have been improved. 65C186 branch instructions are now recognised, and the plugin can now identify branches to unnamed labels, which are indicated with a different icon. Lastly, this version corrects a bug which prevented these line markers from appearing.

This change adds warnings for unresolved references within the same assembly file, and also highlights unused declarations. The result is not correct for projects which include symbols from other files (as opposed to importing them), so this feature may be disabled per-project via an intention action.

A new weak warning has been added to suggest padding hex and binary numbers to a whole byte, since eg. 7 digit binary numbers often indicate a problem.

This change adds intention actions for converting numeric literals between hexadecimal, decimal and binary representations.

It also adds a completion helper for assembly language mnemonics, an inspection to indicate when unsupported mnemonics are used, and a quick-fix for switching the CPU target to one which includes the unsupported mnemonic.

The 'Generic 6502 Project' template has also been improved.

This change adds 'Go to definition' and 'Find usages' support for constants and imports, and allows for labels to be auto-completed when entering text after an assembly mnemonic.

Code folding has also been overhauled, and now supports macro definitions, conditional blocks, and a number of other constructs. A code folding bug has also been corrected, where keywords such as .proc and .scope were incorrectly interpreted as case sensitive.

The "6502 Assembly" file type now includes files with the .mac extension, which is used by ca65 macro definitions.

This change adds compatibility with 2021.3 IDE releases.

This change adds a project template for generic 6502 projects, plus compatibility with 2021.2 IDE releases.

This change improves the refactor/rename feature for labels.
