• Added special cases to the python autocomplete so it includes the methods listed in the drop-down
  • declaring any variable as “mySF = ScriptFascades()” will successfully bring up auto complete options for mySF later in the script
  • same deal for “myTable = mySF.dbQuery(…”, myTable will be recognized as a dbTable object
• Left the dropDown in the GUI because there’s a few options I can’t reproduce like identifying an alertInfoObject and constructors

This blog is much more active than the old viz-n blog…

Moved on to new svn and got everything building.

Continuing work on the python introspection stuff.  Making tangible progress now:

• Using the info script defined here: http://diveintopython.org/power_of_introspection/getattr.html to get introspection information for python objects and classes
• Parsing the result of a hard-coded example and displaying it in the AutoCompleteTextArea component.
• The hard-coded example is working very well and behaves a lot like the eclipse autocomplete save that it can only be initiated by pressing ctrl+space.
• It is also very fast however i am running everything locally so who knows how responsive a remote server will be.
• Now working on splicing the user script up to run info on dynamic parts of it…

• Continuing to work on a python code completion engine.  Phil helped me with some ideas and pointed out a few built in introspection methods in Python.
• Built something basically using the existing visibility script engine to run “info” on the variable in question and a problem arose:
  • For example, say your cursor is at the end of this script:
  • def solrXmlFromListList(doc, root, headers, table):
    for row in table:
    rowNode = doc.createElement(‘doc’)
    root.appendChild(rowNode)
    for i in xrange(len(headers)):
    fieldNode = doc.createElement(‘field’)
    fieldNode.setAttribute(‘name’, headers[i])
    textNode = doc.createTextNode(str(row[i]))
    fieldNode.
  • I can’t run info on ‘fieldNode’ without appending info(fieldNode) to the end of the script and executing the entire script which is obviously not an option
  • So basically I need to find a way to run introspection on a script without running any of the script

• The AutoComplete TextArea is pretty much done.  It could use a few small tweaks but those can wait.
• After a fruitless search of “python autocomplete library”, “python code completion library”, etc. I’ve decided to go straight to some source code so I’m currently digging in to the PyDev plug-in for eclipse to see how they do code completion.  Perhaps each language implementation in eclipse uses a similar enough of an API that I can make some backend service for analyzing code and providing autocomplete suggestions.  I’ll just have to add one language at a time.

• Still working on the autocomplete text area with a number of headaches arising
• Created a function for grabbing the compare string out of the text which can then be passed to the filterFunction, unfortunately there is apparently a decent delay between when a user types in a character and when it is actually added to the textField so I was constantly one character behind for awhile until I learned about the “callLater(function)”.  Ah event based programming…
• Keys a user would usually use for navigating the and selecting from the drop-down list also move the text cursor around and add carriage returns so I put in functions to undo the adverse effects after they’ve completed.  Unfortunately I believe these will only work with word-wrap off which is fine for a code/script editor.
• After that was done everything seems to be working fine except for the positioning of the pop-up is still in the top right corner and not near the cursor

• The VisibilityScripting project now has syntax coloring for most script and c-like languages
• Next is autocomplete
