[TWC] trunk remote file for display

[julien23]

Hi all

I am use to display remote code within TW using for example :

<<tiddler UrlContentScript with:../look_app15_raw/matlab/Emt27PowerFilter.m>>

with [[UrlContentScript]] :

<script>
var p;
 if (document.all){
   // For IE, create an ActiveX Object instance
   p = new ActiveXObject("Microsoft.XMLHTTP");
 }
 else {
   // For mozilla, create an instance of XMLHttpRequest.
   p = new XMLHttpRequest();
 }
 p.open("GET","$1",false);
 p.send(null);
wikify(p.responseText,place);
</script>

Sometime I would like to trunck the remote file to display for example only lines 5 to 9.
Can you please help me modify my script ?

Thank you

JBo

Hi Julien,

 

wikify(p.responseText,place);

Sometime I would like to trunck the remote file to display for example only lines 5 to 9.

=>

var out = p.responseText.split("\n");
out = out.splice(5, out.length-9);
wikify(out.join("\n"),place);

Best wishes,

Hi Tobias

Thank you for quick and good idea.

I made it work with :

out = out.splice(5-1,9-5+1);

Final with parametrization :

<<tiddler UrlContentScriptStartEnd with:../look_app15_raw/matlab/Emt27PowerFilter.m 5 9>>

with [[UrlContentScriptStartEnd]] :

<script>
var p;
 if (document.all){
   // For IE, create an ActiveX Object instance
   p = new ActiveXObject("Microsoft.XMLHTTP");
 }
 else {
   // For mozilla, create an instance of XMLHttpRequest.
   p = new XMLHttpRequest();
 }
p.open("GET","$1",false);
p.send(null);

var out = p.responseText.split("\n");

out = out.splice($2-1,$3-$2+1);
wikify(out.join("\n"),place);
</script>

Thanks a lot
