Rebol# or Rebol on DotNET

 [1/10] from: andrew:martin:colenso:school at: 24-Dec-2003 22:40


Just been thinking through this, while learning how to write a Rebol parser in C# (it's very tricky without using Rebol's 'parse...). Looking at the lexer/parse combination, Rebol only seems to need a lexer, because the tokens are Rebol values. The only trickery is balanced braces {} for long string values, and balanced square brackets for blocks [], which could be handled by a stack in the lexer part. My questions are about the interface to .NET stuff. How would we fit Rebol and DotNET functions together? Internationalisation: is it OK to "expand" Rebol's definition of values? For example, a money! Datatype that allows British pounds symbol or Euro symbol? Andrew J Martin Attendance Officer & Grail Jedi. Colenso High School Arnold Street, Napier.

Further thinking: It'd would be nice to have a rebol value that contains units. Like: 12% 50Km/H 60MPH 99.999% And the parts could be accessed like money! datatypes:
>> x: US$123.45
== US$123.45
>> first x
== "US"
>> second x
== 123.45
>>
For example:
>> x: 50Km/H
== 50Km/H
>> first x
== 50
>> second x
== "Km/H"
>>

Even for time value. i.e. 10:00 Would be nice to get the hour or the minutes without parsing. ti: 10:00 ti/2: 30 --> ti: 10:30

Seems to me the time! value already works like that:
>> a: 12:34
== 12:34
>> a/2
== 34
>> a/1
== 12
>> a/2: 44
== 44
>> a
== 12:44
>>

One of the things I've thought about is if it were possible to consume a rebol script as an xml provider http://msdn.microsoft.com/msdnmag/issues/01/09/xml/default.aspx then one can use xml schema to define rebol datatypes, don't much care for xml schema, but the .Net implementation is actually useful, especially as one can do runtime translation between xml schema datatypes and .net datatypes.

basically, we have to wait for the plugin architecture for custom datatypes... What I am designing is a series relationship mapping dialect function for liquid which maps indexes of two series. so you can say map [series-a 1 series-b 34] in this context, some datatypes will have subtypes, identifying their subvalues by name... somewhat like the date and time datatype can do.. thus an equivalent to value: mytime/hours you would first create the relationship with:
>> relationship: map [mytime 'hour value ]
and then can do any of the following: update relationship value update relationship mytime which will automatically (and speedilly) set the corresponding values within a series (or not, depending on the relationship) the map dialect should be able to detect series values and expect an index of some type when it finds one (including subtypes, like 'red 'green or 'blue for tuples, it is even possible that depending on the subtype used, some form of datatype conversion may occur, as an added benefit...). this is to allow liquids to patch to and from series directly... this is not yet done, but part of the eventual design. -MAx

Expanding rebol-syntax? I start having some trouble with this: do it this way. you need a current version of rebol specially when non-gurus talk to others. they try it, it works, they tell it, it breaks. rebol is meant for messaging between humans, and explainung about rebol should be part of the picture. currently rebol works very well (few exceptions). One should be very carefull to change things. each change may help a bit, but it needs an explanation everytime it is used ("it works this way, except except except..") for private fun "introducing new letters" is ok of course :) -Volker Am Dienstag, 14.

No, no! You need one of the beta versions of Rebol for your OS. (pre- Core 2.5.6 not so long ago) :) Andrew J Martin Attendance Officer & Grail Jedi. R(H)ash and impetuous...

At the moment, I'm using .NET Regular Expressions to parse out R# (and Rebol) data types, as .NET will compile these regexp is native code upon loading (and I've got a good tutorial on Regexp in the PERL documentation). If you could provide XML schema definitions and a way to map on .NET regexp or some other way to map rebol values into .NET datatypes, I'll happily include them into R#.

Hmmm, how would we represent something like: 12.5% or: print or: USD$123.45 or: 12.34 ; British Pounds & Pence. ? Block! values are sort of easy enough: <sequence> ; Or some other tag name? ; blah blah </sequence> Andrew J Martin Attendance Officer & Grail Jedi. Colenso High School Arnold Street, Napier.

I'm home right now with a fever, so I'm just gonna give a quick note of the fact that it is possible to use regular expressions inside of xml schema as well, as an extension of strings. However schema usage can be somewhat different than programmatic usage as you don't have the possibility of matching, matching again, checking against the results of two matches before you apply match three. Again the schema usage only seems to me like it would be useful in the context of consuming rebol as an xml provider.
