Even though the goal is that the latest commit on the `main` branch should always be a stable and usable version, this is not the recommended way to install and use `dyff`. If you find an issue with this version, please make sure to note the commit SHA or date in the GitHub issue to indicate that it is not based on a released version. The version output will show `dyff version (development)` for `go install` based builds. @@ -206,4 +206,4 @@ goreleaser build --clean --snapshot ## License -Licensed under [MIT License](https://github.com/tonur/dyff/blob/main/LICENSE) +Licensed under [MIT License](https://github.com/homeport/dyff/blob/main/LICENSE) diff --git a/cmd/dyff/main.go b/cmd/dyff/main.go index 46a996ac..d997b769 100644 --- a/cmd/dyff/main.go +++ b/cmd/dyff/main.go @@ -29,7 +29,7 @@ import ( "github.com/gonvenience/bunt" "github.com/gonvenience/neat" - "github.com/tonur/dyff/internal/cmd" + "github.com/homeport/dyff/internal/cmd" ) func main() { diff --git a/cmd/gendoc/main.go b/cmd/gendoc/main.go index 72b5c2ee..6cbe15f9 100644 --- a/cmd/gendoc/main.go +++ b/cmd/gendoc/main.go @@ -24,7 +24,7 @@ import ( "log" "os" - "github.com/tonur/dyff/internal/cmd" + "github.com/homeport/dyff/internal/cmd" "github.com/spf13/cobra/doc" ) diff --git a/go.mod b/go.mod index db05c23d..e6ffc038 100644 --- a/go.mod +++ b/go.mod @@ -1,4 +1,4 @@ -module github.com/tonur/dyff +module github.com/homeport/dyff go 1.24.9 diff --git a/internal/cmd/between.go b/internal/cmd/between.go index cbb78356..8564a31b 100644 --- a/internal/cmd/between.go +++ b/internal/cmd/between.go @@ -26,7 +26,7 @@ import ( "github.com/gonvenience/ytbx" "github.com/spf13/cobra" - "github.com/tonur/dyff/pkg/dyff" + "github.com/homeport/dyff/pkg/dyff" ) type betweenCmdOptions struct { diff --git a/internal/cmd/cmd_suite_test.go b/internal/cmd/cmd_suite_test.go index 552d3539..ee344edf 100644 --- a/internal/cmd/cmd_suite_test.go +++ b/internal/cmd/cmd_suite_test.go @@ -33,7 +33,7 @@ import ( .
