gofmt as a package

[Albert Strasheim]

Hello all

I am working on a tool that generates some Go code into files.

I would like to format the code like gofmt does.

One option is to run gofmt on the generated files, but it would be
nicer if I could output properly formatted code directly from my
program.

Does anybody have any comments on the idea of moving most of the code
in the gofmt command to a package (maybe called go/format) that can be
used by gofmt and other code generators?

Regards

Albert

Most of the code for gofmt is already in a package.
http://golang.org/pkg/go/printer/

Hello

Thanks. After looking over the extra bits provided by gofmt again, I
think go/printer will do the trick.

You've to use "go/parser" and "go/printer". Here[1] you can see how it
was used by me to get it.

The link by Archos is dead. Is there an example floating around somewhere of how to call gofmt from a go program without using a system call (just for formatting code, I don't need to use the replacement tools)

You want the go/format package:

Thank you Andrew. I didn’t know that existed.
