I am having real issues understanding what is going wrong. When my project was self contained I thought I understood. Now I am trying to package it up I am in trouble. I had a project layout as follows (simplified)
webserver/config/config.go webserver/template/template.go webserver/servermain.go webserver/go.mod servermain.go is a sample project while I get the packages (config and template) right. It also serves as an example so I need to keep it in the project in git. go.mod (contains) require github.com/mygit/webserver v0.0.0-20191018134507-cb1d694390ab // indirect replace github.com/mygit/webserver => ./ This all worked fine, I could update the code in config.go and it would be used in servermain.go without doing any downloads. I commited ALL of this and started a new project with the plan to use config and template package from above. New project layout as follows (simplified) ws2/server2.go go.mod require github.com/mygit/webserver v0.0.0-20191018134507-cb1d694390ab // indirect I could not build this as it kept saying that the module was for servermain.go. I am a little vague hers as this was some time ago. I gave up after a while and restructured the webserver as follows (adding example): webserver/config/config.go webserver/template/template.go webserver/example/servermain.go webserver/example/go.mod >From the 'example' dir I ran 'go mod init' and 'go mod tidy' No problem, it all ran and my go.mod file has: require github.com/mygit/webserver v0.0.0-20191018134507-cb1d694390ab // indirect I realised that config and template had been downloaded in to GOPATH/pkg/mod... If I make changes to config locally they are NOT seen in example/servermain.go. So I set up the go.mod with a 'replace' but I cannot find a path that works. replace github.com/stuartdd/webServerBase => ./ Fails with : build command-line-arguments: cannot load github.com/mygit/webserver/config: module github.com/mygit/webserver@latest (v0.0.0-20191018134507-cb1d694390ab) found, but does not contain package github.com/mygit/webserver/config I have been trying various paths. They either reload GOPATH/pkg/mod (I delete this before each run) and ignote any changes I make to config.go or they fail to find the dependency. What is the correct way to proceed while developing my servermain.go. What is the correct way to proceed when developing servers that import webserver (ws2/server2.go) and use config and template (without a replace in go.mod) I am sure I am missing somthing minor. Could you please help.
