[racket] Suggestion for saving preferences

Hello list. I am trying to figure out a way to save the state of an app and I am having trouble trying to come up with a decent solution, so I figure that is wise to ask wiser people :) The state of the app is given by several different structs such as this one: ;; algorithm contains : ;; a na

Re: [racket] slatex and conference papers

I've had trouble with that process, due to different systems' handling of "dot-files". The most reliable way is to paste the contents of each .Z file in place of the slatex code that generates them. Also remember to include slatex.sty with your submission. Carl Eastlund On Mon, Apr 4, 2011 at 5

Just run slatex on your end. It will produce a whole bunch of .Z*tex files that you can send to the other side along with the slatex latex package (in your directory.) Jay 2011/4/4 Neil Toronto : > I've just had a paper that uses slatex accepted for publication at a > Springer conference. The pro

I've just had a paper that uses slatex accepted for publication at a Springer conference. The proceedings won't be put together using our camera-ready PDFs, but from the sources. How can I package the sources so that everything compiles neatly on a system that doesn't have slatex? Neil

Re: [racket] Solumns: evil version of columns

Interesting program. You blog that it is too slow, so I took a look at your code. I expect you could speed it up substantially with a few changes to the data structures and so on. Some hints: - Classes are going to be slower than functions and structures - Use fxvector for a vector of integers a

Re: [racket] scribble secref does not render consistently between HTML and PDF

I'm inclined to call this a documentation bug, both because the docs for `secref' are partly specific to HTML and because there's no documentation of the Latex commands to redefine to control the generated section reference. For Latex/PDF output, the section title is currently only included for th

Re: [racket] scribble secref does not render consistently between HTML and PDF

Since PDF is intended for the world of printed papers, the rendering process follows the grammatical rules of the printed media. Those dictate that sections, chapters, etc. are referred to via numbers. Why those conventions developed the way they did is beyond the scope of this email but we try
