Use as a library?

[stevefan1999-personal]

I want to put this in a Rust build script so I don't have to run the generator every time. I wonder if there is a way to interface with the re2rust program as a library?

Not at the moment. There is libre2c, but it exists for a different purpose (it exposes only DFA construction algorithms and does not include code generator). Can you explain your setup a bit more, e.g. why it would be a problem for the build script to call an external program? Is it not what build scripts usually do?

Well, I can't assume the user always have re2c installed

I had a similar issue in my Cmake project. Can you download re2c.exe as a pre-build event and execute it for the *.re files? How is the fact that it is a library going to help? Or do you mean you want re2c to be a rust crate that you can reference?
