Rendering on an external stream

Hi,

I need to write a seaside component which understands
#renderContentOn: on an external file.
Let's say that the component is called componentToPrint, what I want
to do is to redirect the output (what gets written on the html
document) of

html render: componentToPrint

on an external stream.

How can I do it?

cheers
Marco

Re: Rendering on an external stream

You can get a string with

string := html class builder render: componentToPrint

Does that help?

It would get more complex if you actually want to stream it. You'd
probably want to make a new WAHtmlStreamDocument and configure it with
"html context document:" (putting the old document back afterwards) or
even create a new rendering context altogether (see
WARenderContinuation>>processRendering: for an example) . My memory of
how this works in 2.8 is a bit fuzzy at the moment; you'd have to play
to get it right.

I found it myself :-)

What I needed was something like this:

WARenderCanvas builder render: componentToPrint

Hi Marco,

have a look at WAHtmlBuilder. It can be used to write html to an
arbitrary stream.

Cheers,
Lukas

Hi,

I do something like that:

contents := (WARenderCanvas builder)
        fullDocument: true;
        rootBlock:
                [:root |
                    root meta
                        contentType: self session contentType
                        charset: self session charSet];
        render: [:html | componentToPrint renderContentOn: html].
