AltME: Parse

Messages

Andreas: 20:45But for this particular use, Rebol 3 now has a _much_ better tool: SPLIT.
Bo: 20:47I learned something already. :-)

sqlab: 08:47it works in R2. as even
>> parse "a b c" {,}
== ["a" "b" "c"]
breaks at white spaces
Gabriele: 09:48don't forget that PARSE str "," (or any other delimiter), in R2 at least, is meant to parse CSV lines, so it has some built in magic that may surprise you if you're not aware of it.

09:48>> parse {a,b,c} ","
== ["a" "b" "c"]
>> parse {a,b,c d} ","
== ["a" "b" "c" "d"]
>> parse {a,b,"c d"} ","
== ["a" "b" "c d"]
>> parse {a,b,"c d,e"} ","
== ["a" "b" "c d,e"]

09:49note also:
>> parse/all {a,b,c d} ","
== ["a" "b" "c d"]
>> parse/all {a,b,c,d} ","
== ["a" "b" "c" "d"]
>> parse/all {a,b,"c,d"} ","
== ["a" "b" "c,d"]
sqlab: 09:55Just at what I wanted to point

Geomol: 17:50Would it makes sense to let
parse "abc" [3 char!]
be the same as
parse "abc" [3 skip]
Geomol: 18:01Maybe letting this be true is better:
parse "abc" [word!]
Like this is true:
parse "123" [integer!]

Rondon: 21:11Hi Folks, I'm having problem to parse the '&' commercial symbol. I'm using web-to-plain.r from rebol.org, but the 'Inc names, I'm having problem to parse it.. any clues ?

21:13My problem is because I have some html entities starting with &, but the problem is to find just companies such as AT&T, A&E, Film&Arts and transform this loner '&' to '&'

NickA: 02:20Rondon, so, the company names are always sandwiched between two other characters -is that correct? Are the html entities always characterized by a different matching pattern (not sandwiched the same way)?
Arnold: 05:27We have a company/restaurant in Holland that is called Keuk& (translation Kitchen). Otoh the amp is not allowed in urls is it?
An idea might be to hardcode these few examples and transform them in an extra parse step, or just before returning the value from the db.

05:29(forget the remark about url and &).
Rondon: 12:25yes.. Nick

12:28I will have to scan all the "&" and compare this with html entities (&, ´) if those two words between '&', I have to keep those words and replace '&' with "&".
Rondon: 12:33I was trying to make a patch to web-to-plain.r from rebol.org

Tomc: 23:09@Rondon would love to see what you come up with, web-to-plain.r changes web encoded chars to accii plaintext so emitting an "&amp" in place of an "&" in the input would be counter to its nature. maybe describe the problem a bit more, what the input is and what needs to be changed in the output. Just looking at it now (after a decade) I think I would at least change the call from parse to parse/all
