OGDL for Go
Package ogdl is used to process OGDL, the Ordered Graph Data Language.
OGDL is a textual format to write trees or graphs of text, where indentation and spaces define the structure. Here is an example:
network ip 192.168.1.100 gw 192.168.1.9
The languange is simple, either in its textual representation or its number of productions (the specification rules), allowing for compact implementations.
OGDL character streams are normally formed by Unicode characters, and encoded as UTF-8 strings, but any encoding that is ASCII transparent is compatible with the specification and the implementations.
This implementation does not support cyles (OGDL Level 2).
The documentation of the package is kindly generated by godoc.org.

Use the ogdl-go list, if necessary.
Example: a configuration file
If we have a text file 'conf.g' like this:
eth0 ip 192.168.1.1 gateway 192.168.1.10 mask 255.255.255.0 timeout 20
g := ogdl.ParseFile("conf.g") ip,_ := g.GetString("eth0.ip") to,_ := g.GetInt("eth0.timeout") println("ip:",ip,", timeout:",to)
ip: 192.168.1.1, timeout: 20
