Not at the moment but you could use the IScriptTextDocument interface to search and change the Structured Text (ST) parts of the POUs.

Here some example code for finding the textual parts:

def getFullName(obj):
   str = ""
   while obj is not None and not obj.is_root:
      str = obj.get_name() + '.' + str
      obj = obj.parent
   return str
proj = projects.primary
\# Iterate through all children of the project
for child in proj.get_children(True):
   hasDecl = child.has_textual_declaration
   hasImpl = child.has_textual_implementation
   if hasDecl or hasImpl:
      print("=== Object with text: {} declaration={} implementation={}".format(getFullName(child), hasDecl, hasImpl))
      if hasDecl:
         declaration = child.textual_declaration
         print("Length of declaration: " + str(declaration.length))
         print("Content of declaration:\n<code>")
         print(declaration.text)
         print("</code>")
      if hasImpl:
         implementation = child.textual_implementation
         print("Length of implementation: " + str(implementation.length))
         print("Content of implementation:\n<code>")
         print(implementation.text)
         print("</code>")

To change the content of a textual part you use the method . There are more methods you can use, see the Scripting API documentation.

Python script to automate 'Find and Replace'

2020-02-27T14:51:55.222000Z

Hi all,

I'm new to Python scripts and I am wondering if this is possible to script:

Before finishing a project I always run a couple of Find and Replace actions (with regex), for example:
Find: [\t ]+(\n)
Replace: $1

Can I make a Python script that automates this process? So it runs a couple of Find and replace actions in a row?

Will it use native CODESYS Find and replace functionality, or do I just program a regex search in Python?

Thanks
