Add WitchHazel by Thea Flowers

I have tested the addition using go test, but I would like to do some more testing (and visually inspect the output) before removing draft status.

Please forgive my ignorance, but I am new at go and cannot figure out how to install the binary for testing (go build and go install are both quiet).

[alecthomas]

go build will place it in the working directory

[alecthomas]

However you should add some actual tests to really be sure. Follow the README in lexers.

[stefanv]

go build does not produce anything as far as I can tell. It also looks like none of the other styles have tests associated with them.

[alecthomas]

Ah sorry, I didn't read the code - the tests are for the lexers. go build will only produce an executable for a main package. I would build the chroma executable and use that:

go run ./cmd/chroma -s witchhazel SOMEFILE

[stefanv]

Thanks, @alecthomas, that's helpful. This is where my inexperience with go is a problem; I'm sure it must be obvious, but when I run go run ./cmd/chroma I get:

go run: no packages loaded from ./cmd/chroma

Maybe I need some environment variable set, or a newer version of go? I have:

go version go1.17.3 linux/amd64

Feel free to just point me to a manual or website; I can teach myself if I have a rough sense of where to look.

[alecthomas]

Sorry that is my bad. I forgot that I made chroma a separate Go module. You'll need to do:

cd ./cmd/chroma
go run . -s witchhazel SOMEFILE

[stefanv]

This worked well, and I was able to confirm that the theme renders as expected (I compared it with the Pygments output):

[alecthomas]

Awesome, thanks :)
