Hi,
I'm developing an application to support third-party extensions that filter
text. Each filter consists mainly of a property list and an executable. The
idea is that the text of the current document goes into the executable along
with settings specified in the property list (as arguments); text to replace
the document text comes out as the standard output.
Right now I am stuck trying to decide how I should pass both the document
text and the settings to the executable. I see three options:
1. Have the first argument be the document text, and the second an XML
string containing the settings as key-value pairs.
2. Have the first argument be the docucument text, the second a setting
key, the third a setting value, the fourth a setting key, etc...
3. Have the first argument be the docucument text, have each successive
argument be a setting value, in an order specified in the property list so
as to determine the key for each.
I can easily set up the application to support any of these methods. My
problem is that each one seems to have some inconveniences for the developer
of the filter, and I would like to make this as convenient as possible for
anyone who makes a filter. Could someone tell me which method would be the
most appropriate?
Thanks.
