How to parse the contents of a file?

Hi Sanramz,

What Andrew said.

You are also missing a level of parens in the let( (cv) ... ) of
create_boundary. As I was reindenting your code to get a better view, I
couldn't help but split it into a couple of procedures as suggested by
Andrew; the following seems to work for me:

;; File format:
;;
;; cell_name llx lly urx ury
;; BUF 0 0 4.448 4.424
;; AND 0 0 4.448 4.424

procedure(MyCreateBoundary(libName cellName llx lly urx ury)
let( (cv)
cv = dbOpenCellViewByType(libName cellName "layout" "maskLayout" "w")
dbCreateRect(cv list("prBoundary" "drawing") list(llx:lly urx:ury))
dbSave(cv)
)
) ; procedure

procedure(MyCreateCells(libName listPath)
let( (inPort line fields values)
inPort = infile(listPath)
if(inPort then
while(gets(line inPort)
;; Split on *any* whitespace--gets rid of the trailing \n.
fields = parseString(line)
;; Will contain nils if some fields cannot be converted.
values = mapcar('atof (cdr fields))
if(length(fields) == 5 && !memq(nil values) then
;; Looks good.
apply('MyCreateBoundary libName car(fields) values)
else
warn("Skipping malformed line with fields %L" fields)
)
)
close(inPort)
else
error("Unable to open %L for reading" listPath)
) ; if
) ; let
) ; procedure

MyCreateCells("test" "/home/san/tiler/cell_list")

Cheers, -D

free to use the reformatter to make your code easier to read!
