💻 Usage

General

$ docker run --rm cytopia/goimports --help

Usage: cytopia/goimports [flags] [path...]
       cytopia/goimports [--ci] [-local] [-srcdir] [path...]
       cytopia/goimports --help

Dockerized version of goimports with an addition to fail (exit 1) in case of file changes.

Additional wrapper features:
----------------------------
 --ci   This option will print the diff to stdout (similar to '-d') and if a diff
        exists it will fail with exit 1.
        Can only be combined with '-e', '-local' and '-srcdir'.
        To be used in continuous integration with explicit failing.

Default goimports flages:
----------------------------
 -cpuprofile string
        CPU profile output
 -d     display diffs instead of rewriting files
 -e     report all errors (not just the first 10 on different lines)
 -format-only
        if true, don't fix imports and only format. In this mode, goimports is
        effectively goimports, with the addition that imports are grouped into sections.
 -l     list files whose formatting differs from goimport's
 -local string
        put imports beginning with this string after 3rd-party packages; comma-separated list
 -memprofile string
        memory profile output
 -memrate int
        if > 0, sets runtime.MemProfileRate
 -srcdir dir
        choose imports as if source code is from dir. When operating on a single file,
        dir may instead be the complete file name.
 -trace string
        trace profile output
 -v     verbose logging
 -w     write result to (source) file instead of stdout

Default goimports usage

# Print diff to stdout and exit 0
$ docker run --rm -v $(pwd):/data cytopia/goimports -d .

CI wrapper usage

# Print diff to stdout and exit > 0 if diff occurs
$ docker run --rm -v $(pwd):/data cytopia/goimports --ci .
