New features: Read from stdin, new -list, -write and -set-exit-status options (2)

[oncethor]

In order to make this utility usable as goimports is, added capabilities to:

• read from stdin
• just list the files which need formatting/sorting
• return 1 to the shell so that it can stop a loop

You can now do things like: $ echo $(git diff --cached --name-only --diff-filter=ACM | grep ".go") | \ xargs goimports-reviser -list -output write -file-path

or

$ git --no-pager show :"reviser/reviser.go" | goimports-reviser -list

or define a git alias like this:

goimportsrev = !echo $(git diff --cached --name-only --diff-filter=ACM | grep .go) \ | xargs goimports-reviser -list -output write -file-path \ | xargs git add

In a complex project, even though it does not have the possibility to work on an entire subtree, it can be used with a Makefile to analyse the subtree and stop on the first change needed.
