Go fmt on a whole source tree

Question

I have a project currently organized something like this:

~/code/go
         /bin
         /pkg
         /src
             /proj/main.go
                  /some_packa         


        

Answer 1

Also, you can try to run command:

go fmt ./...

from your project directory.

Answer 2

find proj -type f -iregex '.*\.go' -exec go fmt '{}' +

Explanation

• find proj: find everything in this directory...
  • -type f: ...that is a file
  • -iregex '.*\.go': ...and case-insensitively matches the regular expression .*\.go
• ...and execute go fmt followed by as many matched files as the operating system can handle passing to an executable in one go.

Answer 3

The command gofmt ./... mentioned by some, does not work on Windows (at least on my Win7).

Instead of it, I used gofmt -d .\ which works recursively. I use the -d flag because I want to list the changes I need to make in order to pass the check.

NB: golint ./... does work on Windows, just gofmt ./... doesn't.

Answer 4

You can use three dots (...) as a wildcard. So for example, the following command will format all github.com packages:

go fmt github.com/...

This wildcard also works with other go commands like go list, go get and so. There is no need to remember such an ugly find command.

Answer 5

if you are using GoLand IDE, right click on project and you will find Go Tools.

Answer 6

If you use gofmt instead of go fmt, it's recursive. For example, following command

gofmt -s -w .

(notice the little dot at end) recursively formats, simplifies, and saves result into every file under current directory. I have a shell alias gf defined as gofmt -s -w . and find it quite handy.

Try gofmt -l . (list files whose formatting differs from gofmt's) first if you want :-)
