forbidigo is a Go static analysis tool to forbidigo use of particular identifiers.
forbidigo is recommended to be run as part of golangci-lint where it can be controlled using file-based configuration and //nolint directives, but it can also be run as a standalone tool.
go get -u github.com/ashanbrown/forbidigo
forbidigo [flags...] patterns... -- packages...
If no patterns are specified, the default pattern of ^(fmt\.Print.*|print|println)$ is used to eliminate debug statements. By default,
functions (and whole files), that are identifies as Godoc examples (https://blog.golang.org/examples) are excluded from
checking.
A larger set of interesting patterns might include:
^fmt\.Print.*$-- forbid use of Print statements because they are likely just for debugging^fmt\.Errorf$-- forbid Errorf in favor of using github.com/pkg/errors^ginkgo\.F[A-Z].*$-- forbid ginkgo focused commands (used for debug issues)^spew\.Dump$-- forbid dumping detailed data to stdout
Note that the linter has no knowledge of what packages were actually imported, so aliased imports will match these patterns.
- -set_exit_status (default false) - Set exit status to 1 if any issues are found.
- -exclude_godoc_examples (default true) - Controls whether godoc examples are identified and excluded
To prevent leaving format statements and temporary statements such as Ginkgo FIt, FDescribe, etc.
You can ignore a particular issue by including the directive //permit on that line. This feature is disabled inside golangci-lint to encourage ignoring issues using the // nolint directive common for all linters (nolinting well is hard and I didn't want to make an effort do it exactly right within this linter).
Pull requests welcome!
