Hi,
Thanks. In the latest version of all Grease packages and the print: method is not around
in the Stream hierarchy.
So, for is it Ok to have the fix in BOLatexWriter>>visitInternalLink: by replacing
stream with latex to work with print: or do you see problems there?
Cheers,
Doru

Yes, this is intentional: 'stream' is the raw
low-level stream, 'latex' is the high-level encoded stream. The choice to which
you send the output is important. Changing it likely breaks the generation of valid
LaTeX.
GRPharoUtf8CodecStream or better its abstract superclass should implement #print:. I
think this was discussed in the Seaside list recently and fixed, but I might be wrong.

Hi,
I am testing Pier 2 some more, and now I got a problem in the Latex writer. Specifically,
I do not quite understand the difference between the latex instance variable and the
inherited stream one.
Take a look at the snippet below:
BOLatexWriter>>visitInternalLink: anInternalLink
...
latex tab ... square: [ stream nextPutAll: 'width='; print:
((anInternalLink parameterAt: 'width' ifAbsent: [ 100 ]) asNumber / 100.0); ... ]
When executed on a book we have two instance variables:
- stream: instance of GRPharoUtf8CodecStream (inherited)
- latex: instance of BOLatexStream which wraps stream
Now, it so happens that GRPharoUtf8CodecStream does not understand print:, but this
method exists in BOLatexStream. I fixed the code by replacing stream with latex in the
above method, and it works.
But, there are still other places that use stream, and I think they should all use the
BOLatexStream instance instead. So, my question is: Is this intentional? Or maybe should
we actually simply override the setting of stream and use that one for everything?
Cheers,
Doru
