The answer by Axel Wagner is somewhat helpful but the output of "go version -m ..." is meant for human consumption and hard to reliably parse by a program. On my system (where I haven't performed any updates in several months): > go version -m /opt/bin/goimports /opt/bin/goimports: go1.23.0 path golang.org/x/tools/cmd/goimports mod golang.org/x/tools v0.24.0 h1:J1shsA93PJUEVaUSaay7UXAyE8aimq3GW0pjlolpa24= dep golang.org/x/mod v0.20.0 h1:utOm6MM3R3dnawAiJgn0y+xvuYRsm1RKM/4giyfDgV0= dep golang.org/x/sync v0.8.0 h1:3NFvSEYkUoMifnESzZl15y791HH1qU2xm6eCJU5ZPXQ= build -buildmode=exe build -compiler=gc build DefaultGODEBUG=asynctimerchan=1,gotypesalias=0,httplaxcontentlength=1,httpmuxgo121=1,httpservecontentkeepheaders=1,panicnil=1,tls10server=1,tls3des=1,tlskyber=0,tlsrsakex=1,tlsunsafeekm=1,winreadlinkvolume=0,winsymlink=0,x509keypairleaf=0,x509negativeserial=1 build CGO_ENABLED=1 build CGO_CFLAGS= build CGO_CPPFLAGS= build CGO_CXXFLAGS= build CGO_LDFLAGS= build GOARCH=arm64 build GOOS=darwin build GOARM64=v8.0 Apparently my current version of goimports is v0.24.0. After updating my Go related CLI tools (via "go install golang.org/x/tools/...@latest") running "go version -m /opt/bin/goimports" reports /opt/bin/goimports: go1.23.0 path golang.org/x/tools/cmd/goimports mod golang.org/x/tools v0.26.0 h1:v/60pFQmzmT9ExmjDv2gGIfi3OqfKoEP6I5+umXlbnQ= ... It's not obvious to me how to reliably extract the relevant version from the "go version -m" output for a specific CLI tool. Should there be a reliable way to programmatically do so? I'm inclined to answer "yes" but it's not obvious that should be done by something like "go version -m ..." or something like "/path/to/command -json -version". Obviously all of the approaches discussed involve running an external command and parsing its output. Which has its own set of problems regardless of the output produced by that command. And, obviously, how do you handle a command named "goimports" installed by the user that is not from the golang.org/x/tools repository. -- Kurtis Rader Caretaker of the exceptional canines Junior and Hank -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
