a little bash script. OK so, my cmd line skills are slowly improving and
I can install these widgets in
/usr/local/bin/some_cool_tool.sh # on my OSX box, G4 Powerbook
e.g.
SEARCH_PATTERN=$1
locate index.shtml | while read INDEX_FILE; do
fgrep -H -i "$SEARCH_PATTERN" $INDEX_FILE
done | more
exit 0
(wow, that is soooo concise!)
and then in Revolution set up a button:
on mouseUp
put empty into fld "results"
set the shellCommand to "/bin/sh"
put "/usr/local/bin/web_content_search.sh" & quote & fld "findString"
& quote
into tShellCmd
put shell (tShellcmd) into fld "results"
end mouseUp
It all works, is very "sweet" And it is a *lot* faster than using
transcript
for the same job. *but* Only problem is: it is blocking... and this is
documented behavior:
Here is my way around this problem. The example below is for a "ping"
command, but I'm sure you can adapt it to your stuff.
As you can see, I direct the output of the shell command to a
temporary text file. The second part of the shell command containing
the "2>&1 &" is the relevant section. I don't understand it but it
works :-) The rest of the script just loops around checking to see if
there is anything in this file and then parsing the result. Since it
uses wait with messages, it is non-blocking.
HTH,

function checkPing pIP
put specialFolderPath("Desktop") & "/ping.txt" into tFileName
if there is a file tFileName then delete file tFileName
put "ping -c1 -n " & pIP into tShellCmd
put " > " & tFileName & " 2>&1 &" after tShellCmd
get shell(tShellCmd)
put 0 into timeCheck
repeat 50 times
add 1 to timeCheck
wait 1 tick with messages
if there is a file tFileName then
put URL ("file:" & tFileName) into tRes
if tRes is empty then next repeat -- file created but no result yet
put wordOffset("loss", tRes) into tWord
if tWord = 0 then next repeat -- file created but result
not complete
-- if there is a file tFileName then delete file tFileName
put word tWord-2 of tRes into tPercent
if tPercent = "0%" then return true
else return false
end if
end repeat
if there is a file tFileName then delete file tFileName
return false
end checkPing
