Go Language Learning Tips (i)

The boundary of the defer

Defer is a function-bound, that is, it will only run when the current function is going to exit.

Return of Nested Channel Select

① for nested the same channel select, how to want to return layers, the best way is to directly close the channel

Package Mainimport ("FMT", "Time") Func main () {stopc: = make (chan int) go func () {select {case <-stopc:fmt. Println ("Stopc 0") Select {case <-stopc:fmt. Println ("Stopc 1")}fmt. Println ("Stopc 2")}} ()//Stopc <-2//stopc <-2close (STOPC) time. Sleep (time. Second * 5)}

Fork the correct posture of the other project

For example, there is a project "Http://github.com/sirupsen/logrus", you see he is a little uncomfortable want to pity dorado things. So fork a new project "Http://github.com/auxten/logrus", but the code will have a lot of "import" Http://github.com/sirupsen/logrus/xxx ""

You go directly to modify the code project will still refer to the original, pull request the original author can not be passed quickly, urgent, how to do?

①go get someone else code, here is

Go get Github.com/sirupsen/logrus

② add a new remote to your project directly, pointing to your own repo, command:

git remote add auxten [email protected]:auxten/logrus.git

③ Create a new branch, called the Aux Bar, and let the branch point to this remote. Command:

git checkout-b aux && git branch-u auxten/master aux

④ the final. Git/config probably looks like this:

[core]    repositoryformatversion = 0      filemode = true    bare = false     logallrefupdates = true    ignorecase = true     precomposeunicode = true[remote  "origin"]    url =  https://github.com/sirupsen/logrus        fetch = + refs/heads/*:refs/remotes/origin/*[remote  "Auxten"]    url = [email  protected]:auxten/logrus.git        fetch = +refs/heads/*: refs/remotes/auxten/*[branch  "aux"]    remote = auxten         merge = refs/heads/master[push]    default =  upstream 

⑤push code is used

git push-u auxten aux:master

This command means: Push and set the upstream of Aux to Auxten master.

The method is not perfect, but at least it is more elegant to solve the problem of local development compilation.
