For future reviewers: Note there is no equivalent to String#rchop for StringLiteral which might've been nice for this.

Could be tweaked a bit:

Suggested change
VERSION = {{`#{LibLLVM::LLVM_CONFIG} --version`.chomp.stringify.gsub(/git/,"")}}
VERSION = {{ `#{LibLLVM::LLVM_CONFIG} --version`.chomp.stringify.gsub(/git$/, "") }}

Hm, actually there's no need for a regex:

Suggested change
VERSION = {{`#{LibLLVM::LLVM_CONFIG} --version`.chomp.stringify.gsub(/git/,"")}}
VERSION = {{`#{LibLLVM::LLVM_CONFIG} --version`.chomp.stringify.gsub("git","")}}

There is no StringLiteral#sub, either

@straight-shoota There is, if you want to remove the git from the end of the string only.

@HOMODELUNA WDYT of making it work with the string instead of the redex as proposed by @straight-shoota?

That wouldn't work either, the macro StringLiteral#gsub requires a RegexLiteral first argument

And of course, moving the .gsub or .sub outside {{ ... }} isn't an option as LibLLVM::VERSION's initializer must be a literal

Okay, so we leave everything as it is. Sorry for all the confusion 🙇

IMO $ should be added, still.

Let's add it as is, and if at some point we see the need to restrict further the regex (i.e., to be at the end as suggested by Sija), we do it then.
