goprintconst

If you use Go constants as the source of truth in your build, you might end up reading their values like this:

> grep -e "MySpecial.*=.*" "foo/bar.go"
    MySpecial    = "value"

This operation can be error-prone: The regular expression might be incorrect, commands like grep or cut might be unavailable. By walking the Go abstract syntax tree (AST) to find constants, goprintconst makes the operation reliable.

Use

All constants (default):

> goprintconst --path foo/bar.go
MySpecial="value"
AnotherSpecial="foo"
ThirdSpecial="bar"

One constant:

> goprintconst --path foo/bar.go --names MySpecial
MySpecial="value"

Two constants:

> goprintconst --path foo/bar.go --names MySpecial --names AnotherSpecial
MySpecial="value"
AnotherSpecial="foo"
