Extract (and process) comments/free labels from a VI (or VIs)

[hornseyma]

What I would like to be able to do is extract the labels (specifically the free labels) from all the VIs in my project. I then plan to process the labels to extract information (specifically any lines tagged with, say, and @ symbol) and dump this out to documents.

Does anyone know how to, using LabVIEW, extract the free labels from a VI?

More generally, the reason why is I would like to be able to automatically generate documentation for my VI (much like you can do with, say, Javadocs).  I've had a look at Bookmarks and this doesn't quite seem to do what I'm after (e.g. can't extract it, can't processes it, can't format the output, etc.) but I may have missed something.

Many thanks,

You can do that using scripting.

There are plenty of examples on the forum, here are a couple.

Hi hornseyma,

specifically any lines tagged with, say, and @ symbol

See the bookmarks feature of recent LabVIEW version for inspiration - it uses the # char.

The bookmark manager is open to look under the hood…
