Help: Searching part of string in list

frasheed over 11 years ago

Hey,

Can anyone give me hint to serach part of string in list.

Example:

partName = "newStar"

fullNames = '("oldStarwork" "newStarWork" "loadStar" "halfStarwork")

if Icheck it with member(partName fullNames) then will return nil but I want "newStarWork" as answer, I read the documenattion there is only member and memq functions are deifned for seraching lists . I looke the function recmatchp but its jist for symbol or strings and I have list (fullNames)

rexMatchList(partName fullNames)
If that hadn't have been available, you could have done:
rexCompile(pattern)
setof(fullName fullNames rexExecute(fullName))
But rexMatchList does this for you.
Andrew.

Hey Andrew, rexMatchList is working fine for list but rexMatchp is not working properly for some cases. Example:
I have a layout that has two gates g1 and g2 , and I am writing code to add a new property called "fix" to the instTerms
so code goes like
procedure(CCFaddInstPinLabels(@optional (cellView geGetEditCellView()))
let( (transform pinCenter)
foreach( inst cellView~>instances
    transform=inst~>transform

    foreach( instTerm inst~>instTerms
     case(instTerm~>name
      (rexMatchp("g" instTerm~>name)
        dbSetq(instTerm "G" fix)
       )
   ); case
); foreach instance terminal
); foreach instance
);let
); procedure CCFaddInstPinLabels
but it's not setting up the propert, the problem is with matching , if I write (rexMatchp("s" instTerm~>name) then its workin fine, because there is only one source and "s" matches with the instTerm~>name.
Can you please tell me is this method ok ?

    case(instTerm~>name
      (rexMatchp("g" instTerm~>name)
        dbSetq(instTerm "G" fix)
       )
   ); case
Case is the wrong function to use, try cond. Case evaluates its first argument and then checks for the block designated by the matched string/integer.
Cond executes each condition (like an if/then/elif/else in other languages) and executes the block for the first condition that returns true.
   cond(
      (rexMatchp("g" instTerm~>name)
;; Fix the g terminals
        dbSetq(instTerm "G" fix)
       )

      (rexMatchp("s" instTerm~>name)
;; fix the s terminals
        dbSetq(instTerm "S" fix)
       )
   ); cond
And you might want to better qualify your search, what begins with "g" is "^g"
