What seems to be the problem? Running ./premake5 --help in a directory with corrupted premake5.lua will only show error.

What did you expect to happen? premake5 --help show warning, ignore the premake5.lua file, and show other help information.

What have you tried so far? Delete or rename bad premake5.lua.

How can we reproduce this?

mkdir test-premake
cd test-premake
cp /whatever/path/to/premake5.exe .
./premake5 --help
echo aaaaa > premake5.lua
./premake5 --help

What version of Premake are you using? ~~Error: F:/Works/test-premake/premake5.lua:2: syntax error near ~~

Anything else we should know?

premake5.lua might add extra options to the help (extra command lines, extra modules, ...), so to be accurate, executable has to read the file.

@Jarod42 I think it should show other help information if failed to parse the premake5.lua file

Changing from bug to enhancement. One of the implicit prerequisites to Premake is valid input. If the input isn't valid, we do not currently ensure a defined behavior.
