We often focus on binary size, but do you know the size of the files inside the module cache for your project? On a CI, this may lead you to "no space left on device" I created a small tool to calculate module cache size for a module. github.com/ldez/gomodca... #golang

I created a new linter to detect calls which can be replaced by methods from the testing package. github.com/ldez/usetest... This new linter will be available in the next version of golangci-lint (v1.63). Support my work: bento.me/ldez #golang #golangcilint

> ./golangci-lint run example_test.go:41:18: os.CreateTemp("", ...) could be replaced by os.CreateTemp(t.TempDir(), ...) in TestSample (usetesting) tmpFile, err := os.CreateTemp("", pattern) example_test.go:46:17: os.MkdirTemp() could be replaced by t.TempDir() in TestSample (usetesting) tmpDir, err := os.MkdirTemp("", pattern) example_test.go:51:17: os.TempDir() could be replaced by t.TempDir() in TestSample (usetesting) otherTmpDir := os.TempDir() >

I added an option to the `gomoddirectives` linter: it forces the usage of patch 0 (ex: 1.22.0) or go family (ex 1.22) as min go version. github.com/ldez/gomoddi... This feature will be available in the next version of golangci-lint (v1.63). Support my work: bento.me/ldez #golang #golangcilint

$> go mod edit -go=1.22 > ./golangci-lint run go.mod:3:1: go directive (1.22) doesn't match the pattern '\d\.\d+\.0$' (gomoddirectives) go 1.22 > go mod edit -go=1.22.3 > ./golangci-lint run go.mod:3:1: go directive (1.22.3) doesn't match the pattern '\d\.\d+\.0$' (gomoddirectives) go 1.22.3 > go mod edit -go=1.22.0 > ./golangci-lint run$ $linters: enable: - gomoddirectives linters-settings: gomoddirectives: # Defines a pattern to validate `go` directive. go-version-pattern: '\d\.\d+\.0$'$

I updated `tagliatelle` linter, you can now define the naming rules of struct tags by package. github.com/ldez/tagliat... This new feature will be available in the next version of golangci-lint (v1.63). Sponsor my work: bento.me/ldez #golang #golangcilint

Example of linter configuration:

linters:
enable:
- tagliatelle

linters-settings:
tagliatelle:
case:
rules:
json: camel
overrides:
# Ignore a package.
- pkg: my/pkg
ignore: true
# Use different rules by package.
- pkg: my/otherpkg
rules:
json: snake
