I have used LaTeX and latex-beamer for pretty much my entire life of document and presentation production, i. e. since about my 9th school grade. I’ve always found the LaTeX syntax a bit clumsy, but with good enough editor shortcuts to insert e. g. \begin{itemize} \item...\end{itemize} with just two keystrokes, it has been good enough for me.

A few months ago a friend of mine pointed out pandoc to me, which is just simply awesome. It can convert between a million document formats, but most importantly take Markdown and spit out LaTeX, or directly PDF (through an intermediate step of building a LaTeX document and calling pdftex). It also has a template for beamer. Documents now look soo much more readable and are easier to write! And you can always directly write LaTeX commands without any fuss, so that you can use markdown for the structure/headings/enumerations/etc., and LaTeX for formulax, XYTex and the other goodies. That’s how it should always should have been! ?

So last night I finally sat down and created a vim config for it:

"-- pandoc Markdown+LaTeX -------------------------------------------

function s:MDSettings()
    inoremap <buffer> <Leader>n \note[item]{}<Esc>i
    noremap <buffer> <Leader>b :! pandoc -t beamer % -o %<.pdf<CR><CR>
    noremap <buffer> <Leader>l :! pandoc -t latex % -o %<.pdf<CR>
    noremap <buffer> <Leader>v :! evince %<.pdf 2>&1 >/dev/null &<CR><CR>

    " adjust syntax highlighting for LaTeX parts
    "   inline formulas:
    syntax region Statement oneline matchgroup=Delimiter start="\$" end="\$"
    "   environments:
    syntax region Statement matchgroup=Delimiter start="\\begin{.*}" end="\\end{.*}" contains=Statement
    "   commands:
    syntax region Statement matchgroup=Delimiter start="{" end="}" contains=Statement
endfunction

autocmd BufRead,BufNewFile *.md setfiletype markdown
autocmd FileType markdown :call <SID>MDSettings()

That gives me “good enough” (with some quirks) highlighting without trying to interpret TeX stuff as Markdown, and shortcuts for calling pandoc and evince. Improvements appreciated!

As part of the Ubuntu App Developer Week, I just ran a live on-air session on how to internationalize your Ubuntu apps. Some of the participants on the live chat asked me if I could share the slides somewhere online.

So here they are for your viewing pleasure :) If you’ve got any questions on i18n or in Ubuntu app development in general, feel free to ask in the comments or ping me (dpm) on IRC.

Enjoy!

On next Monday this cycle’s Ubuntu Application Developer Week classes will start.

The topic that kept me busy most in this cycle was Python gobject-introspection, and porting pygtk2 apps to PyGI (see my initial steps and my report from the PyGI hackfest.)

To spread the love, there will be two talks about this next week: On Monday 17:00 UTC the very Tomeu Vizoso himself will explain what gobject-introspection (“GI”) is, why we need it, and how library developers use it to ship a good and useful GI binding (“typelib”) for application developers. I will then follow up on Tuesday 16:00 UTC about the app developer side, in particular how to use the GI typelibs in Python, and how to port PyGTK2 applications to PyGI.

For the most part these sessions are distribution neutral (we don’t have any special sauce for this in Debian/Ubuntu, it all happened right upstream :-) ); only a very small fraction of it (where I explain package names, etc.) will be specific to Debian/Ubuntu, but shouldn’t be hard to apply to other distributions as well.

So please feel invited to join, and bombard us with questions!
