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 |
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).
