• 05:05 UTC (new) (history) 2017-05-01 show-some-last-messages . . . . Marcin Borkowski – I am pretty sure I am not the only one annoyed by the fact that I can’t see more than one message in the echo area at a time. I have some functions I put in some hooks which display certain messages, and of course only the last one is usually visible. Of course, I could switch to the *Messages* buffer (using C-h e, for instance), but then I’d have to press C-x 1 to delete its window. And what if I have more than one window and I press C-h e? Not fun. I’m pretty sure its configurable to some extent, but I wanted something different. I wanted to have something like momentary-string-display. I didn’t, however, like the fact that it mangled the text in the buffer I’m in, even if only temporarily. Well, actually the best thing to use would be… message.

• 16:58 UTC (new) (history) 2017-04-24 Many variants of a Beamer presentation – part III . . . . Marcin Borkowski – Some time ago I [[2016-09-05 Many variants of a Beamer presentation – part I|wrote]] [[2016-10-03 Many variants of a Beamer presentation – part II|about]] making both a presentation and lecture notes out of a single source in Beamer. I’m still using the setup shown there, but recently I encountered an unexpected problem. Consider this: {{{ \documentclass{article} \usepackage{beamerarticle} \begin{document} \begin{frame} \frametitle{A frame with a theorem} \begin{theorem} A~cool theorem. \end{theorem} \end{frame} \begin{frame}<presentation> \frametitle{A~presentation-only frame with a theorem} \begin{theorem} Another theorem, visible only on a~presentation. \end{theorem} \end{frame} \begin{frame} \frametitle{Another frame with a theorem} \begin{theorem} The final theorem. \end{theorem} \end{frame} \end{document} }}} If you compile this, you’ll spot the problem immediately: while the second theorem is not present in the pdf, its //number// is taken up, and we have Theorem 3 right after Theorem 1. (In case of the {{{beamer}}} document class, everything works just fine – try it if you want.) It does make sense. Imagine a Beamer theme which actually does typeset theorem numbers. You would like then your theorem labels in the presentation and in the lecture notes to match. Usually, this is not the case, though, and I don’t really care for theorem numbers in the slides. So, here’s my simple solution. (While at that, I also turn the frametitles off in the lecture notes. If you want to do that automatically for all slides, see [[https://tex.stackexchange.com/q/350020/5626|here]].) {{{ \documentclass{article} \usepackage{beamerarticle} \theoremstyle{plain} \newtheorem*{theorem*}{Theorem} \begin{document} \begin{frame} \frametitle<presentation>{A frame with a theorem} \begin{theorem} A~cool theorem. \end{theorem} \end{frame} \begin{frame}<presentation> \frametitle{A~presentation-only frame with a theorem} \begin{theorem*} Another theorem, visible only on a~presentation. \end{theorem*} \end{frame} \begin{frame} \frametitle<presentation>{Another frame with a theorem} \begin{theorem} The final theorem. \end{theorem} \end{frame} \end{document} }}} CategoryEnglish, CategoryBlog, CategoryTeX, CategoryLaTeX, CategoryBeamer

While it sounds unbelievable, it’s actually believable; it is in fact the thing most worth believing. I wish to all my Catholic readers the joy coming from Our Lord’s Resurrection; the joy which will last much longer than our life on this earth. To all the rest I wish that you may find that joy. I hope to see all of you in Heaven one day! As usual, I am going to offer a decade of Rosary for all people reading this. Hallelujah!

• 12:58 UTC (new) (history) 2017-04-09 Quickly loading and finding your elisp files . . . . Marcin Borkowski – This is a rather obvious hint – at least with hindsight – but someone might find it useful. If you’re like me, you may have a bunch of short elisp files with various small utilities you have written yourself in the past few years. For some reason, you may not want to load them at startup (maybe you want your Emacs to start as fast as posibble, maybe you don’t want to pollute the namespace with things that are only occasionally useful…).
