Re: xml literals

[Damien MATTEI <Damien dot Mattei at unice dot fr>]

works... yes but , i have find some interesting clues:

-still needing to use the literal to avoid the error:
Exception in thread "main" java.lang.Error: gnu.kawa.xml.MakeElement does not implement Externalizable
if you issue a literal:toString it avoids the compiler trying to "Externalize" an object it does know how to externs but know how to do it for it for String

example:
(set! html-literal
     	   #<td align="center">&[html-literal-table]</>)
     
     (set! html-literal-str (html-literal:toString))

no compile error

the problem is not specific to function call style but also with # literal, but after all perheaps it is the side effect of set! returning a literal which should be avoid in the code... i do not know.

-(simple ) slicing, a Kawa only feature seems to do not work always in literals, here his some test examples:

 ;;(apply html:table literal-rows-list)) ;; OK
	   ;;(html:table literal-rows-list)) ;; OK but non-sense
	   ;;(html:table @literal-rows-list)) ;; KO
	   ;;(html:table option-lst literal-rows-list)) ;; OK but non-sense
	   ;;(html:table @option-lst @literal-rows-list)) ;; KO
	   ;;#<table DIR="LTR" BORDER="1" width="312" id="table_observateurs">&[@literal-rows-list]</>) ;; KO
	   ;;#<table DIR="LTR" BORDER="1" width="312" id="table_observateurs">@&[literal-rows-list]</>) ;; OK
	   ;;#<table DIR="LTR" BORDER="1" width="312" id="table_observateurs">POPUP</>) ;; OK
	   ;;#<table>POP UP</>) ;; OK
	   ;;(html:table "POP UP")) ;; OK

for example this works:

(set! options-and-arguments-lst
	   (append option-lst literal-rows-list))

        (set! html-literal-table
	   (apply html:table options-and-arguments-lst)) ;; OK

but not those:
;;(html:table @literal-rows-list)) ;; KO
	   ;;(html:table option-lst literal-rows-list)) ;; OK but non-sense
	   ;;(html:table @option-lst @literal-rows-list)) ;; KO

the good thing is i finally succeed in making my program (in attachments) compiling and running by melting function call style and literal list but the both are working
 if you take some special cautions with side-effects and slicing too.

the output is not human readable:
<td align="center"><table xmlns="http://www.w3.org/1999/xhtml"; DIR="LTR" BORDER="1" width="315" id="table_observateurs"><tr><td DIR="LTR" ALIGN="LEFT">RGY</td><td DIR="LTR" ALIGN="LEFT">NuLL</td></tr><tr><td DIR="LTR" ALIGN="LEFT">LM</td><td DIR="LTR" ALIGN="LEFT">NuLL</td></tr><tr><td DIR="LTR" ALIGN="LEFT">BSL</td><td DIR="LTR" ALIGN="LEFT">NuLL</td></tr><tr><td DIR="LTR" ALIGN="LEFT">KHA</td><td DIR="LTR" ALIGN="LEFT">  ? ? </td></tr><tr><td DIR="LTR" ALIGN="LEFT">TME</td><td DIR="LTR" ALIGN="LEFT">  ? ? </td></tr><tr><td DIR="LTR" ALIGN="LEFT">TM</td><td DIR="LTR" ALIGN="LEFT">?</td></tr><tr><td DIR="LTR" ALIGN="LEFT">ABT</td><td DIR="LTR" ALIGN="LEFT">Abetti G.</td></tr><tr><td DIR="LTR" ALIGN="LEFT">AFR</td><td DIR="LTR" ALIGN="LEFT">Africano</td></tr><tr><td DIR="LTR" ALIGN="LEFT">AHN</td><td DIR="LTR" ALIGN="LEFT">Ahnert P. von</td></tr>.......

i think there is a way to include in Kawa literal some non interpreted character,i see in the doc, to have some  human readable html page,i will try this later.

Damien
