parse problem

[parser]

I don't understand why it does parse only partially by extracting only y and not z :

input: {x op1 y op2 z}

rules-partial: [
thru " op1 " copy text1 to " op2 " (ask text1) thru " op2 " copy text2 to newline (ask text2)
(probe text1 probe text2 ask "")
]

parse input rules-partial  

-----------
Pasting above in the console it only gives me y and not z:


>> input: {x op1 y op2 z}
== "x op1 y op2 z"
>>
>> rules-partial: [
[    thru " op1 " copy text1 to " op2 " (ask text1) thru " op2 " copy text2 to newline
 (ask text2)
[    (probe text1 probe text2 ask "")
[    ]
== [
    thru " op1 " copy text1 to " op2 " (ask text1) thru " op2 " copy text2 to newline
(ask text2)
    (probe text1 probe text...
>>
>> parse input rules-partial
y== false
>>

I don't see a newline in input's string, so I assume that's your problem.  Either add one.  ie...

Code:

input: {x op1 y op2 z^/}

or instead of using to newline, use to end.

Hope that helps.

Hi, thanks but I tried with end and it does give the same result

>> input: {x op1 y op2 z}
== "x op1 y op2 z"
>>
>> rules-partial: [
[    thru " op1 " copy text1 to " op2 " (ask text1) thru " op2 " copy text2 to end (as
k text2)
[    (probe text1 probe text2 ask "")
[    ]
== [
    thru " op1 " copy text1 to " op2 " (ask text1) thru " op2 " copy text2 to end (ask
 text2)
    (probe text1 probe text2 as...
>> parse input rules-partial
y== false
>>

Please note that you are redefining INPUT, and using ASK. See the source of ASK:

Code:

ask: func [
   "Ask the user for input."
   question [series!] "Prompt to user"
   /hide "mask input with *"
][
   prin question
   trim either hide [input/hide] [input]
]

Anyway:

Code:

>> parse/all "x op1 y op2 z" [thru "op1" copy text1 to "op2" "op2" copy text2 to end]
== true
>> text1
== " y "
>> text2
== " z"
