go

Playing with go. Late to the party, but it's fun, I think.

thoughts

• fast
• some level of type-safety (just scratched the surface so far)
• good tool support (fast (!) compilation, the go tool itself, fetching libraries built-in, though versioning is missing)
• simple (mostly, goroutines + no proper sync will bite you, thinking helps, as always)

qst - run things quickly (and easily)

intended to be run in unfamilar environments, you pass it a file or a directory and it tries to detect what it is and how to run it.

• run qst or qst -h to see options and support project types

• qst hello_world.go: compiles and runs hello_world.go, rerunning after it exits or the file is saved

  quite fun for small things, just throw some code in a file, have qst watch and restart when appropriate.

• qst -phase=test ... runs the tests for projects that support it

Building it yourself

# set up $GOPATH as desired
$ export GOPATH=$PWD/.go         # choose whatever you want
$ go build qst
...
$ ./qst -h
Usage: qst <file>
...
$ ./qst examples/hello_web.rb
...
^C
$ ./qst examples/hello_web.go
...

Try changing something in the files, it's fun. :)

Ideas/todo

• watch many files (select by globbing)
• sometimes restarts twice after one save?
• more project types
• tests (how? lots of shellscripts could do it, but would be very cumbersome. current "architecture" doesn't allow mocking.)
