# goconst
|
|
|
|
Find repeated strings that could be replaced by a constant.
|
|
|
|
### Motivation
|
|
|
|
There are obvious benefits to using constants instead of repeating strings, mostly to ease maintenance. Cannot argue against changing a single constant versus many strings.
|
|
|
|
While this could be considered a beginner mistake, across time, multiple packages and large codebases, some repetition could have slipped in.
|
|
|
|
### Get Started
|
|
|
|
$ go get github.com/jgautheron/goconst/cmd/goconst
|
|
$ goconst ./...
|
|
|
|
### Usage
|
|
|
|
```
|
|
Usage:
|
|
|
|
goconst ARGS <directory>
|
|
|
|
Flags:
|
|
|
|
-ignore exclude files matching the given regular expression
|
|
-ignore-tests exclude tests from the search (default: true)
|
|
-min-occurrences report from how many occurrences (default: 2)
|
|
-min-length only report strings with the minimum given length (default: 3)
|
|
-match-constant look for existing constants matching the values
|
|
-numbers search also for duplicated numbers
|
|
-min minimum value, only works with -numbers
|
|
-max maximum value, only works with -numbers
|
|
-output output formatting (text or json)
|
|
|
|
Examples:
|
|
|
|
goconst ./...
|
|
goconst -ignore "yacc|\.pb\." $GOPATH/src/github.com/cockroachdb/cockroach/...
|
|
goconst -min-occurrences 3 -output json $GOPATH/src/github.com/cockroachdb/cockroach
|
|
goconst -numbers -min 60 -max 512 .
|
|
```
|
|
|
