I know Satimage has some regular expressions to handle such a thing.
Would anyone (Emmanuel) have some code that will return the line that
contains a match at the start of the line. Example:
Search string: "Macdonalds"
Result is the line:
"Macdonalds McDonalds"
Since it starts with the search string.

Hey Hanaan,
This is one is particularly easy:
----------------------------------------------------------------------
set theText to "
GM General Motors
Macdonalds McDonalds
MicroSoft Microsoft
"
try
set findIt to find text "^Macdonalds.+" in theText with regexp and
string result without case sensitive
on error
set findIt to false
end try
----------------------------------------------------------------------
The pattern is: "^Macdonalds.+"
^ == beginning of line
. == any character
+ == one or more
----------------------------------------------------------------------
If you're operating directly on a file you can use that in the reference:
set theFile to alias "some:file:path"
try
set findIt to find text "^Macdonalds.+" in theFile with regexp and
string result without case sensitive
on error
set findIt to false
end try
----------------------------------------------------------------------
The Satimage osax does line-based regex by default; however, you can make
it greedy by using flags:
Line regex:
try
set findIt to find text "" in theText regexpflag {"EXTENDED",
"NEWLINE", "ICASE"} with regexp and string result
on error
set findIt to false
end try
Greedy regex:
try
set findIt to find text "" in theText regexpflag {"EXTENDED", "ICASE"}
with regexp and string result
on error
set findIt to false
end try
Using a try block is necessary, because "find text" will throw an error
if it doesn't find anything.
[CC'd due to the slowness of the list.]
