Gohint is an alternative linter for Go source code. It is based on golint and inspired by jshint. That is, basically gohint is the same golint plus configuration (plus some extra checks, plus report generators, plus... :) )
To install, run go get github.com/elgris/hint/gohint
Any other documentation you can check at golint's README. At the moment there is not so much difference, but I'm not sure what will happen in future :)
Why you may need it? As golint says:
The suggestions made by golint are exactly that: suggestions.
Golint is not perfect, and has both false positives and false negatives.
But sometimes you want those suggestions to work, so you start to use the tool in your continuous integration. And after that you begin to realize that many of those suggestions do not fit your project and just add noise to health report.
That's why you can try gohint - you can configure it, so it will scream only
in case of problems that really hurt your project. Don't try to filter the noise,
define your rules and do not produce such noise! :)
Also it can produce reports in various formats, so integration to your CI cycle becomes even easier. At the moment it supports only 2 formats: plain text and Checkstyle XML.
gohint supports 2 options that can be passed:
| opt | description |
|---|---|
config |
path to JSON file with configuration. See above how to prepare config file |
reporter |
name of reporter to use for output. Supported ones: plain and checkstyle. plain outputs report in plain text (like golint) and is used by default. checkstyle outputs Checkstyle XML |
Example:
gohint -config="/path/to/config.json" -reporter=plain
JSON config can contain following options:
TBD...
| opt | type | description |
|---|---|---|
| package | bool | analyze package comments, definitions, etc |
| imports | bool | check imports for . |
| names | bool | check names of functions, variables, etc |
| exported | bool | check exported types and vars for correct comments and other |
| var-decls | bool | analyze variable declaration for correctness |
| elses | bool | check if..else statements for redundant else |
| make-slice | bool | check making slices for using short syntax |
| error-return | bool | check list of function's return values for position of error, it should be last |
| ignored-return | bool | check if there any function call which returned result is ignored |
| min-confidence | float | minimal confidence value to reduce output, [0..1] |
