- 1. My First Three Months in GO Brett Anderson
- 2. Who Am I? 4th Year CS Student at Macewan University Started learning Go professionally with no prior experience Used it for a web-development job under Bellstone Engineering
- 3. Focus of the talk Features of Golang Struggles learning it in a professional setting What I wish I would have known if I could go back and start again
- 4. Setup Sublime + GoSublime Start with C (Pointers will make more sense)
- 5. Godoc 1 Go documentation is easily found 2 Documentation > Stack Overflow(for the most part) 3 https://godoc.org/github.com/gorilla/mux
- 7. Syntax var myVar bool No semicolons Enforced if/else syntax := assignment syntax
- 8. Functions and Returns Functions have similar syntax to regular declaration func (r receiver) funcName (parameters) (return) Can return multiple things at once
- 9. Structs, Slices, Objects(ish) There are no objects in Go Frankenstein your own with method calls Slices are like arrays, but faster Maps exist in go
- 11. Interfaces Interfaces are a great way for defining a family of objects Square/Circle as shapes Interfaces are implicit
- 12. Embedded Types You can embed those interfaces we just saw This is as close to inheritance as Go gets
- 13. Closures & Wrapping Incredibly Useful for programming with 3rd party libraries Return a func that matches what you need See closure.go
- 14. Useful Libraries in Golang
- 15. Go Templating Dynamic HTML is easy {{.object}} notation Html/template text/template
- 16. Time Package Weird at first but versatile once you get the hang of it Most important date, Mon Jan 2 15:04:05 -0700 MST 2006 (Parse into this)
- 17. Database/sql Really easy to connect to any DB(PostGres, mssql, sqlite) Just need the specific driver (for us its lib/pq) Last months talk was all on DB’s in GO Great encapsulation
- 18. Testing/Logging Go has a very flushed out testing suite You can nest tests Go test –v shows you the hierarchy Structured logging for machine readable logs Package github.com/aybabtme/log This was discussed in the July meetup Testing Logging
- 19. Gorilla Mux Fleshed out router for go Makes grabbing parameters from URL super simple
