https://gophersnippets.com uses Github issues for comments, powered by https://utteranc.es/. You can add comments directly on the corresponding Github issue or use the comment form under each code section.
You are welcome to contribute testable Go code snippets.
Please read the following before submitting a PR:
- https://blog.golang.org/examples
- https://blog.golang.org/playground
- https://github.com/golang/go/wiki/TableDrivenTests
- Include only one code snippet per PR
- The snippet should be small and solve one problem only
- Include comments when necessary
- When you submit a PR the following checks will run automatically:
-
code includes at least 1 test or testable example
-
code runs successfully on play.golang.org
-
code passes go vet
-
code includes a category and a title in the first line of the code (Category: Title)
// Strings: How to reverse a string // package main
or includes a category and title in the first line of the code, an empty comment line and then a description
// Strings: How to reverse a string // // Description // package main
-
code should be included in one file only, named main_test.go. This is necessary in order to test and run snippets locally
-
folder should match the slug version of the title:
if the title is How to reverse a string,
the folder should be snippets/how-to-reverse-a-string
and the full path should be snippets/how-to-reverse-a-string/main_test.go
