常用示例
Compile Lua script to bytecode
luac -o [output.luac] [script.lua]
Compile multiple scripts
luac -o [combined.luac] [script1.lua] [script2.lua]
Parse and syntax check only
luac -p [script.lua]
List compiled bytecode
luac -l [script.lua]
List with full debug info
luac -l -l [script.lua]
Strip debug info from output
luac -s -o [stripped.luac] [script.lua]
Show version
luac -v
说明
luac compiles Lua source code into bytecode. The compiled output loads faster and can be distributed without source code. Syntax checking with -p validates scripts without creating output. This is useful in build processes and CI pipelines to catch errors early. The listing option (-l) shows the bytecode instructions, helping understand Lua's virtual machine and debug compilation issues. Double -l adds local variable and upvalue information. Stripping debug info (-s) reduces file size but removes line numbers and local variable names, making debugging harder. Use for production deployment where size matters. Multiple input files combine into a single output chunk. When executed, each file's code runs in order. Bytecode format is version-specific and not portable between different Lua versions. Lua 5.1, 5.2, 5.3, and 5.4 have incompatible bytecode formats.

How do I run a basic luac example?
Run `luac -o [output.luac] [script.lua]` in a terminal, then adjust file names, paths, flags, or remote targets for your system.
What does -o _FILE_ do in luac?
Output compiled bytecode to file.
