I handle forms in my version control. I use a method to get all form objects
into an object-its an object of my own format…here is a sample below. Pretty
extensive. I have code to pack and unpack the form objects so i can compare
current version of a form with the last one (not using diff) to tell me in
plain english what is changed. The object is put into t blob and written out to
a version control document
the object is build using a call like this...
CORE_T_ParseFormName:=$_aT_FormNames{$_L_Index}
FORM LOAD($_aT_FormNames{$_L_Index})
C_OBJECT($CORE_ob_FormObject)
CLEAR VARIABLE($CORE_ob_FormObject)
CORE_GetFormObjects ($_aT_FormNames{$_L_Index};0;->$CORE_ob_FormObject)
I have put a copy of CORE_GetFormObjects on my
dropbox..https://www.dropbox.com/s/banb0mpgllkj8na/CORE_GetFormObjects.txt?dl=0
its fairly self explanatory if a little wordy..its shockingly fast i mean
really uncompiled ‘boom' all them form objects parsed into an object faster
than a fast thing.
If I was modifying it i would not have the constants hard coded as i now have
code I got from the forum for reading the names of all 4D constants.
Three caveats….
1) if you try to get the menu bar of the form i think you just get the current
menu bar(i build my menus on the fly anyway so this is not an issue for
me)..but it can lead to you being told the menu bar has changed!
2) If you use inherited forms when you parse a form you get the inherited form
objects and you can have an object named the same on the inherited form as on
the inheriting form(!) and when you get the form objects they don't always come
in the same order, this can lead to an object x on the inherited form being
found in the array of objects before the object on the inheriting form on pass
and then next time after-which can lead to you reporting that the object type
has changed-i just make sure my object names on inherited forms are unique!
3)There are a couple of properties you can't get-they are as follows:-
//the following form setting cannot be obtained in code
//Markers
//access
//menu bar
//print settings
//appearance
//form type
//inherited form table
//inherited form name
//save geometry
(This is on V14 maybe on 15/16 you can get these)
this(without much comment) is the code i use to report the differences between
two form objects(current and previous)

I have recently added a ‘watcher’ process which looks for all forms modified
since the last time it looked(it looks every few mins) and if a form is
modified runs code to compare it and save a new version of the object out.
Happy to hear from anyone with comment/critique on this code.
