Re: [go-nuts] Where to stick temporary go files after an AST rewrite?

[Matt Mueller]

Oh that's brilliant, I didn't realize $GOPATH acted like $PATH. Haha, seems 
obvious when writing it out, but I thought it was just an environment 
variable. Thanks Matt!

Re: [go-nuts] Where to stick temporary go files after an AST rewrite?

[Matt Harden]

You can put them anywhere on your GOPATH. So for example, if you're on a
unix-y system, $HOME/go is normally your GOPATH, and you want to rewrite
the file $HOME/go/src/github.com/my/repo/hello.go, you could store the
rewritten file at /tmp/go/src/github.com/my/repo/hello.go, and run the go
tool with the GOPATH environment variable set to /tmp/go:$HOME/go. This
would cause the tool to find the rewritten file before the original. If
there are other files in the same package that you are *not* rewriting, you
may have to copy those anyway to the new directory; I'm not sure whether
the go tool expects all files in a package to be in the same directory or
not.

The way to call "go run" from Go is to use the os/exec
 package to literally
run the command.

[go-nuts] Where to stick temporary go files after an AST rewrite?

[Matt Mueller]

Hey folks!

I'm using the new https://godoc.org/golang.org/x/tools/go/ast/astutil#Apply 
function, but keep running into the question:

After I rewrite these files, where do I stick them so they're still 
buildable with the rest of the program? Is there anyway to call "go run" 
after modifying the AST of these files? 

Thanks!
