godebug

Small library of tools for debugging Go (golang) programs.

The most useful of these is LF(). It returns a line number and file name. The parameter is an optional number. 1 indicates that you want it for the current call. 2 would be the parent of the current call.

Example:

	package main

	import (
		"fmt"

		"git.q8s.co/pschlump/dbgo"
	)

	func main() {
		dbgo.Printf("I am at: %(LF), data %(J)\n", []string{1,2,3})
	}

LF() takes an optional parameter, 1 indicates the current function, 2 is the parent, 3 the grandparent.

I will add complete documentation tomorrow.

Formats:

Format	Description
%(LF)	print out line number
%(j)	convert data using json.Encode and output with indentation
%(J)	convert data using json.Encode and output

ChkEnv

Return true if the passed environment variable can be parsed to be a true value. Values are cached so that the os.Getenv is only called once for each variable.

There is a test in ./test/test.sh to test this (or use the Makefile).
