cannot specify module path

[MeteorsLiu]

Our team uses llcppg to compare the user-provided llpkg with the generated result to ensure the safety of llpkg.

However, llcppg cannot specify the module path for go.mod, which causes the failure of our verification process.

In above examples, the module path of user-provided llpkg is github.com/goplus/llpkg/cjson while the llcppg generated one is cjson, which's not equal.

okay,i deem it is a nessary feature, may use the modulePath in llcppg.cfg to config the go.mod's modulePath and if dont config this modulePath , and default use the name in llcppg.cfg as the module path.

@xushiwei @aofei @tsingbx what about your views.

use the modulePath in llcppg.cfg to config the go.mod's modulePath and if dont config this modulePath , and default use the name in llcppg.cfg as the module path.

Works for me.

modulePath+name作为go mod init 模块名称。

[luoliwoshang]

modulePath+name作为go mod init 模块名称。

我认为这里的行为更像go mod init 的行为会更合适，允许用户传递任何的modulePath，modulePath+name 会导致用户对于modulePath的作用产生误解，并且当用户希望package name 和 modulePath尾部的name不一致时，这个方案就会无法解决。

I think the behavior here would be more appropriate if it were similar to go mod init, allowing users to pass any modulePath. The modulePath+name approach would cause users to misunderstand the purpose of modulePath, and this solution wouldn't work when users want the package name to be different from the name at the end of the modulePath.

By default, llcppg doesn't generate go.mod. Use -mod <ModPath> to generate go.mod and go.sum.
