Lua decompiler support "lua51,lua52,lua53,lua54,luajit"

Features

Block and dominator-tree based analysis, which can help to eliminate most of middle-variables correctly
Drawing control flow graph, you can visit the original lua instructions in each block
Custom parser support, which can help you to decompile unofficial lua bytecode
Optimized output for multiple-line string
Multipule encoding support

Change Log

2023/10/08

Enhancement for LuaJIT:
- Updated instruction adaptation for the latest Luajit2 (slight differences in call instruction parsing when "BCDUMP_F_FR2" is included in the header flags).
- UCLO instruction handling for LuaJIT, which commented as "close: {} -- jump: {}" in previous
UI: Bytecode disassembly highlighting and formatting adjustments.

2023/10/06

UI enhancement: Display bytecode disassembly, constants tables
Fixed: Luajit constant parse error https://github.com/metaworm/luac-parser-rs/issues/12

2023/8/22

Decompilation optimization: Analyze the relationship variable references via SSA
Optimize decompilation speed
Fixed: Invalid "-- implicit variable refs by block" introduced due to improper handling of loadnil instruction
Fixed: Analysis issues of some jump instructions https://github.com/metaworm/luac-parser-rs/issues/8

2023/7/18

New ctrlflow graph
Fixed the issue with too many invalid "-- implicit variable refs by block" comment

2023/7/16

Added support for handling the TSETM instruction for luajit.
Fixed vararg parsing for lua52-lua54 and luajit.
Fixed the issue with misalignment in function call argument handling for luajit.

2023/7/15

Fixed the issue where switching to a custom parser didn't load immediately.
New feature: Name filtering for file list/function list.
New feature: Support batch drag-and-drop for decompiling multiple files.
UI improvement: Moved the configuration interface to the bottom right.
Architectural optimization: Engine returns AST, local storage, and local output results.

2023/7/11

Decompilation optimization: Fix the panic: index out of bounds error that occurs when restoring table lists.

2023/7/9

Optimize decompilation output: Display bytecode disassembly code as comments when decompilation fails.
Add file list view: Save decompiled files locally for convenient review and viewing.
