Commands

qrun

Enhancement: run <gopSrcFile> as a Go+ script. See qrun for more detail.

Thanks contribution of jiangz222 (jiangzhi@goplus.org).

qfmt

Format Go+ packages, similar to go fmt. See qfmt for more detail.

Usage: qfmt [flags] [path ...]
  -w	write result to (source) file instead of stdout

Thanks contribution of visualfc (visualfc@goplus.org), damonchen.

qexp

Generate a Go+ package that wraps a Go package automatically. See qexp for more detail.

Usage: qexp <goPkgPath>

Thanks contribution of xushiwei (x@goplus.org), visualfc (visualfc@goplus.org).

Unix shebang

You can use Go+ programs as shell scripts now. For example:

#!/usr/bin/env qrun

println("Hello, Go+")

println(1r << 129)
println(1/3r + 2/7r*2)

arr := [1, 3, 5, 7, 11, 13, 17, 19]
println(arr)
println([x*x for x <- arr, x > 3])

m := {"Hi": 1, "Go+": 2}
println(m)
println({v: k for k, v <- m})
println([k for k, _ <- m])
println([v for v <- m])

For loop

Thanks contribution of JessonChan (chendongpo@goplus.org)

sum := 0
x := 0
for _, x = range [1, 3, 5, 7, 11, 13, 17] {
    if x > 3 {
        sum += x
    }
}
println("sum(5,7,11,13,17):", sum)
