The bob file is a xml file.  So you can use etree from lxml package to manipulate the file with python.

I'm sorry I didn't make myself clear. I wish to know how to create and write XML file using jython/python script in phoebus? Is there a way to find and replace charactors especially pv_names in xxx.bob file?

> Is there "Find/Replace" function still in phoebus? It's very useful for replacing pv names or other things in CSS. Another question I'd like to ask:how to create and write XML file in phoebus? I haven't see it in display builder examples. Any advice or suggestions will be grately appretiated

 

 

Yes, one advantage of the XML file format is that it allows creating or modifying theses files outside of the graphical editor.

We don't try to include a complete XML editor in phoebus, but you can easily add an OS-specific editor to the context menu so that you can then open a display file from the phoebus file browser via the context menu.

 

For example, on Linux you can add a reference to the plain "gedit" text editor like this, so it can then be used to open *.bob or *.opi files and for example perform PV name replacements:

 

org.phoebus.framework.workbench/external_app_text=Text Editor,txt|dat|tab|py|ini|def|db|xml|xsl|css|cmd|sh|st|log|out|md|tex|shp|bob|opi|pvs|edl,gedit

 

You could also register VS code or another more XML-aware editor just for *.bob like that.

 

 

For a general python package that generates display files outside of phoebus, see https://github.com/als-epics/phoebusgen
