Hi Folks... I hope this isn't asking too much. I have found using
the docs to be less than satisfying when trying an alternative
coding technique. I guess I fall into the old dog, actually the
old Hypercard dog, trying to learn the new Rev tricks.
I just wrote a quick and dirty script to parse out an iCal calendar
saved as a text file to feed my car expense calculator which was
published a few months ago in a Rev newsletter. The script is very
slow and I was intrigued to know how to speed it up as I am aware
that I am using very archaic scripting techniques.
Here is my script. It's relatively short and contains almost all
of my favourite coding patterns. If anyone has the inclination,
perhaps you could point out how I might make use of Revs
improvements over Hypercard...
It has to do with better ways to handle repeating actions and
better ways to handle lists... Thanks in advance... Jim
Some clues:
1. Put your fields into variables.
2. Use repeat for each form instead of repeat with i = x to y.
3. If conditions are exclusive use a 'if, else if' form or a switch
structure.
4. Use vars instead of calling many times the same thing:
put char 1 to 4 of item 2 of line i of field 1 into
eventYear -- hold event year - yyyymmdd
put char 5 to 6 of item 2 of line i of field 1 into
eventMonth -- hold event month - yyyymmdd
put char 7 to 8 of item 2 of line i of field 1 into
eventDay -- hold event day - yyyymmdd
put char 10 to 13 of item 2 of line i of field 1
into eventTime -- hold event time
put item 2 of line i of <var> in <another var>
put char 1 to 4 of <another var> into eventYear
put char 5 to 6 of <another var> into eventMonth
etc.
Best regards from Paris,
Eric Chatonet.
