[Parse] Discussion of PARSE dialect

Graham

[1190x3]
SNOMED CT is the one being currently promulgated
and there's the proprietary MEDCIN
so, personal shorthand should expand into a controlled vocab ideally
Tomc

[1193]
yes

Ii Type II Diabetes #250.00
here the macro expansion includes a code (CPT) from the AMA.
Tomc
1-Jul-2006
[1195]
and the macros should  also be part of that  ontology
Graham

[1196x2]
Medcin contains over 100,000 clinical propositions
no one is going to remember that!

Can you make sure that no whitespace sneaks into your macro names?
Graham
1-Jul-2006
[1199]
tom, I can't force the guy to change his macros!
Tomc
1-Jul-2006
[1200x2]
no that is what browaers are for
right
BrianH

[1202]
I mean at the beginning.
Graham
1-Jul-2006
[1203x2]
there is no whitespace inside a macroname
LOINC, another controlled vocab, contains over 30,000 items.
Tomc
1-Jul-2006
[1205]
so there is a seperate extendable file with the macro=expansion
Graham
1-Jul-2006
[1206x2]
tom, yes.
actually  the file will be saved in a database and loaded when the 
program starts
BrianH

Make sure to trim the names before you use them. I am rewriting your 
function.
Graham

Tom, what exactly are you involved in ?
Tomc
1-Jul-2006
[1210x2]
zebrafish
as a model orginism
Graham

[1212]

Ok, I understand the need for an ontology here.
but medicine is full of uncontrolled words which are in common use.
and the ontologically controlled programs are very expensive due 
to licensing fees
The AMA charge to use their codes, the American College of Pathologists 
charge to use their SMOMED-CT codes .. and so it goes on.
LOINC, from the Univ. of Indiana has open sourced their codes.

ahh  my mind is corrupted by giving everything away I forget that 
that is not what everyone does
so back to your problem  I
seems it will take n passes
where n is the # of macros.

expand-macros: func [data [string!] macros [block!]
	/local whitespace macro-rule macro here there
] compose [
	whitespace: (charset " ^/")
    macro-rule: make block! length? macros
	foreach [macro expansion] macros [
        macro-rule: insert insert macro-rule macro '|
    ]
    macro-rule: head remove back macro-rule
    parse/all data [some [
        here: copy macro macro-rule there: [whitespace | end] (

            there: change/part here select/skip macros macro 2 there
        ) :there |
        skip
    ]]
    macro-rule: none
    data
]
Sorry, need to change the settings in my editor.

my first effort makes n passes ...
Tomc
1-Jul-2006
[1227]
that the macro-expansoion fioe needs to self check for incidental 
occurances of  a "macro" in an "expansion" and protect against
BrianH
1-Jul-2006
[1228x2]
This will make one pass.
And it won't have the problem you mention Tomc.
Tomc
1-Jul-2006
[1230]
in one pass you can jump over the expansion
BrianH
1-Jul-2006
[1231]
My code does that.
Graham

[1232x2]
Pretty neat ...
Parse is somewhat beyond my skills!
Tomc

[1234]
I wouls still sort the macros by longest to shortest so cant glob 
on to part of  a macro  ..
Graham
1-Jul-2006
[1235]
so, basically you created a single parse rule from the macro list 
and then parsed the text in one go.
Tomc
1-Jul-2006
[1236]
but if you include the trailing white space that should be avoided
BrianH
1-Jul-2006
[1237]
Tomc, that is a good point - I'll fix it. Graham, that's right.
Graham

Did you compose that without any testing? :)
We need a masterclass in parse ....
