Hi evr'yone
I was wondering about find(). What if there are 2 of the same characters =
in a sequence? Like this:
sequence word
word=3D"beet"
atom findit
findit=3Dfind("e", word)
? findit
Does it give a [2..3] back?
-->Thanks

Hi Thomas,
no it doesn't return a sequence.
>From the manual:-
find
Syntax: i =3D find(x, s) =20
Description: Find x as an element of s. If successful, return the =
index of the first element of s that matches. If unsuccessful return 0. =
Note the key phrase in the manual "index of the first element".
To find all occurrences try this...
sequence result, word
integer x
result =3D {}
word =3D "experience"
for i =3D 1 to length(word) do
x =3D find('e', word)
if x then
result &=3D x
end if
end for
? result -- Should display {1,4,7,10}

Well this sounds like a job for 'experimentation'!!! But since I suspect
you might already know the answer, I'll give you something more to chew
on. Suppose your real question was something like: "How might I get the
indices of all elements found in a sequence?" or "how about all sequences
matched?"
Here's some recursive functions I posted to the list a little while back.
Recursive functions are functions that call themselves to get the answer
you're looking for:
... These return empty sequences if there's no match but I really don't see
the advantage of returning zero since you'd have to store the result in an
object and test for type that way...
-- find_all/match_all recursive functions
-- Brian Broker
-----------------------------
function find_all( object x, sequence s )
-- returns: sequence containing indices of all occurences
-- if unsuccessful return empty sequence {}
object found
found = find( x, s )
if found then
found &= found + find_all( x, s[found+1..length(s)] )
else
return {}
end if
return found
end function
-----------------------------
function match_all( sequence s1, sequence s2 )
-- returns: sequence containing indices of all matches
-- if unsuccessful return empty sequence {}
object found
found = match( s1, s2 )
if found then
found &= found + match_all( s1, s2[found+1..length(s2)] )
else
return {}
end if
return found
end function
-----------------------------
-- test the functions
constant blah = {10,20,3,1,3,4,11,15}
constant names = {"mary","john","mary","frank",""}
constant zippy = {{12,13,14,15},{11,12,13,14,15},{10,11,12,13,14}}
constant
string1 = "My name is Brian. My name is not Thomas. What is your name?",
string2 = "Euphoria is fun. Euphoria is also flexible and fast."
? find_all(3,blah)
---output is {3,5}
? find_all(11,blah)
---output is {7}
? find_all(28,blah)
---output is {}
? find_all("mary",names)
---output is {1,3}
? find_all("john",names)
---output is {2}
? find_all("joebob",names)
---output is {}
---these are tricky ;)
? find(12,zippy)
---output is 0
? find_all(12,zippy)
---output is {}
? match( "name", string1 )
--output is 4
? match_all( "name", string1 )
--output is {4,23,57}
? match( "not", string1 )
--output is 31
? match_all( "not", string1 )
--output is {31}
? match( "Euphoria", string2 )
--output is 1
? match_all( "Euphoria", string2 )
--output is {1,19}
? match( "Python", string2 )
--output is 0
? match_all( "Python", string2 )

Sorry, I meant to add another "bit" to it. I forgot to include =
that the users input was used in find(). So it would be something like:
include get.e

sequence word
word=3D"beef"
atom findit
input=3Dgets(0)
findit=3Dfind(input[1], word) --input[1] otherwise the [#,10] =

So what is your question?
If I input "beer", I will get:
find( 'b', "beef" ) = 1
If I input "elephant", I will get:
find( 'e', "beef" ) = 2
If I input "pork", I will get:
find( 'p', "beef" ) = 0
If I input "Beef", I will get:
find( 'B', "beef" ) = 0
Is this what you want? If not, provide examples like those above and the
result you would like to see. Then we'll see about writing a function that
produces the desired results. Are you looking for a function
like "find_all" or "match_all" that I posted previously?

Um............how about we forget what I wrote. Sorry I've got a lot of
stuff buzzing aroudn right now so I've gotten sidetracked. What I mean is,
if the user enters "e" and Euphoria find()'s "e" in "beet", there are 2.
What happens then? Does Euphoria give you the placement of the first "e".
Sorry for the confusion...

Yes. You can do something like this untested code to gather a list of all
indexes:
function gather( object o, sequence s )
sequence list
list = {}
for i = 1 to length( s ) do
if equal( o, s[i] ) then
list &= i
end if
end for
return list
end function
