This release is based on Go 1.26's gofmt, and requires Go 1.25 or later.
A new rule is introduced to drop unnecessary parentheses around expressions where the inner expression is unambiguous on its own, such as f((3)). Parentheses are kept where they are useful, such as on binary expressions. See #44.
A new rule is introduced to require multi-line function calls to match the opening and closing parenthesis in terms of the use of newlines. See #74.
The -extra flag now accepts a comma-separated list of rule names to enable individual extra rules, rather than enabling all of them at once. See #339.
The following changes are included as well:
- Avoid crashing on
go.modfiles without amoduledirective - #350 - Avoid failing when an ignored directory cannot be read - #351
- Avoid prefixing more kinds of commented-out Go code with spaces - #230
- Avoid prefixing a shebang comment with a space - #237
- Narrow the newlines on assignments rule to ignore complex cases - #354
- Fix three bugs which caused a second gofumpt run to make changes - #132, #345
Binaries built on go version go1.26.2 linux/amd64 with:
CGO_ENABLED=0 go build -trimpath -ldflags="-w -s"
