An unfortunate bug caused a number of packages in old x/tools versions to fail to build with Go 1.25 (https://go.dev/issue/74462). Fix this minimally by updating to the lowest patched version with the fix: v0.24.1. This should allow wire to continue building with the same range of Go versions as it could build with before (down to 1.19). Also: - Update the go.mod go directive to Go 1.19 to allow for module graph pruning, and to be consistent with the minimum build version. - Fix a test that is broken in recent Go versions due to an error message change. - Update tests to run on Go 1.25.x (the most recent version of Go). - Remove coverage, since coverage upload wasn't working anyway. Fixes #431

Wire: Automated Initialization in Go
Wire is a code generation tool that automates connecting components using dependency injection. Dependencies between components are represented in Wire as function parameters, encouraging explicit initialization instead of global variables. Because Wire operates without runtime state or reflection, code written to be used with Wire is useful even for hand-written initialization.
For an overview, see the introductory blog post.
Installing
Install Wire by running:
go install github.com/google/wire/cmd/wire@latest
and ensuring that $GOPATH/bin is added to your $PATH.

Project status
As of version v0.3.0, Wire is beta and is considered feature complete. It works well for the tasks it was designed to perform, and we prefer to keep it as simple as possible.
We'll not be accepting new features at this time, but will gladly accept bug reports and fixes.
