Dave, thanks for sharing your scripts! I figured that matchText could be used to solve
this problem, but I couldn't figure out the syntax for the <regex> parameter (what
does "regex" mean anyway?).
Could you help explain what the following mean, when used with the MatchText function?
1. From matchText(pData,cr & "\[" & pGroup & "\]" & cr & "(.*)",tMatched) :
a. "\[" & pGroup & "\]"
b. "(.*)"
2. From matchText(tMatched, "(" & cr & "\[)", tMatchedx) :
a. "(" & cr & "\[ )"
3. From matchText(tGroup,cr & pKey & "=" & "([^" & cr & "]*)", tResult)
a. "([^" & cr & "]*)"
Thanks again.

Hi Leston
Here are a couple of functions I use to do this. The first one pulls
all data from a section. The second one gets a single key value. As
the second one calls the first one, you'll need both. I haven't
looked at them for a while (but I use them all the time), so I can't
remember why I wrote them as I did. (So much for promises to myself
to document everything!)
Some notes
Only the section name inside square brackets should be on the section
title line. No other text,including spaces, is allowed. The square
brackets shouldn't be passed in the pGroup parameter:
get iniGroup("OPTIONS", myData) -- NOT -- get iniGroup("[OPTIONS]", myData)
lines beginning with ";" are not returned by iniGroup
The local declarations were necessary I think to make "matchText"
work properly.
The functions return "no_group" and "no_key" respectively if the
search fails. Be sure to check for that when calling the functions.
They should probably return empty instead, but I may have had a
reason at the time.
-------------------------------------
function iniGroup pGroup,pData
local tMatched, tMatchedx
put cr before pdata
put cr after pdata
if matchText(pData,cr & "\[" & pGroup & "\]" & cr & "(.*)",tMatched) then
get matchText(tMatched, "(" & cr & "\[)", tMatchedx)
get offset(tmatchedx, tMatched)
if it > 0 then
delete char it to -1 of tMatched
end if
put 1 into tCount
repeat for each line tLine in tMatched
if char 1 of tLine <> ";" and tLine <> empty then
put tLine into line tCount of tResult
add 1 to tCount
end if
end repeat
return tResult
else
return "no_group"
end if
end iniGroup
--------------------------------
function iniKey pKey,pGroup,pData
local tResult
if pGroup is not empty then
put iniGroup(pGroup,pData) into tGroup
else
put pData into tGroup
end if
if tGroup is not "no_group" then
put cr before tGroup
if matchText(tGroup,cr & pKey & "=" & "([^" & cr & "]*)", tResult) then
return tResult
else
return "no_key"
end if
else
return "no_key"
end if
end iniKey
