What's in it

• Byte-exact round trip: an unedited project compiles back to the original .gcx byte for byte; edited projects get every size, offset and table rebuilt. MGO2 stage files are decrypted and re-encrypted automatically.
• Live diagnostics from the compiler — a file with no errors compiles — plus checks for undefined procs, missing resources, strings over 254 bytes, names that hash to something else (e.g. NewSky vs [ce2d24/NewSky], with a quick fix) and typos in new option / command names.
• Autocomplete for @proc / p:proc, options per command, commands and commands.txt handlers, $res: resources, variables, and if / switch snippets.
• Hovers, go to definition, find references and a proc outline; syntax highlighting for scripts and resource files.
• Bundled dictionary.txt and commands.txt name lists (your own copies take priority).
• bin/gcx.js command-line tool with the same engine (Node.js 18+): node bin/gcx.js scenerio.gcx, compile, verify.
