Parsing yaml files in cloverleaf

[Pallav Kumar]

Does anybody have an experience of parsing & mapping .yaml files in cloverleaf? I googled it and there is java library which can convert .yaml to .json. We can then do the mapping from json to json (or vrl, etc) thru xlate.

Curious to know if anybody else has done this before?

Any thoughts are appreciated.

Thanks,

Pallav

Hello, Pallav

There is no need to go to Java. There is a “yaml” package in TCL and it’s available to you in Cloverleaf. So you will have to write some TCL code, but you can parse the “.yaml” file either into a TCL dict or TCL huddle. From there, it’s easy to convert to JSON without an Xlate.

Check the official TCL documentation for examples. Both yaml and huddle are part of Tcllib, which ships with Cloverleaf.

Code:

package require yaml
package require huddle
….

I hope this helps.
