Golang : List all packages and search for certain package
Problem :
You need to find out if a server has the packages that you need to run or compile your Golang source code. What are the tools available to do that?
Solution :
Use go list
command and pipe the output to grep
.
For example, to find out if the gorilla mux package is already imported or not.
go list ... | grep mux
Executing go list ...
will list all packages and pipe the output to grep to check if mux is listed.
IF not, execute go get github.com/gorilla/mux
and repeat go list ... | grep mux
again.
