[Texmacs-dev] Re: [TeXmacs] how to read <write|aux|<tuple|key|value>> data back again

[Sam Liddicott]

Hi Joris;

I had a nasty accident with my email program (typing in the wrong window) and it lost the mail you send about reading a pageref using get-binding, and it's not shown up in the archive yet.

Please could you dig it out of your sent-items for me.

Thanks - and apologies

Sam

Thanks for the info Joris.

A hack would be great. For now I'm only using it to simulate a pageref? Function to tell if a label is defined or not. A pagerefpage function would be cool - to return the un-marked-up page number...

I will be generating the actual programs in awk to start with as the code is already written.

I'll use the dev list now on, I thought it was for C++ questions

You can't, at least not currently. The information is contained in 'buf->aux',
the auxiliary part of your buffer, which is only accessible in the C++ code.
At best, I could add a hack so that you can access it from within Guile.

Anyway, for you litterate programming stuff, you probably want to generate
the actual programs using Guile; this is much easier than endless hacking of
the TeXmacs style files; the style language has not really be designed for
doing non trivial computations. Using Guile, you can simply examine the entire
document tree and perform any computations (and modifications) you want.

Best wishes, --Joris

P.S.: please send developer's questions to texmacs-dev
