[Emacs] compile-command

compile-command is a variable which holds the target for compile command in Emacs. By default, it holds "make -k" , but we can change it if we need a slightly different target. For example, while I am editing my latex files I can set it to "pdflatex myfile.tex".

An easy way to accomplish this is using a file local variable. For my latex file, I added the following comments at the end of the file to set some file local variables.

% Local Variables:
% compile-command: "make -k ch2"
% fill-column: 80
% comment-fill-column: 80
% End:

Local value of compile-command can also be used in source files where someone need to build the whole project instead of only compiling the source targets in the current directory from Emacs.

% Local Variables:
% compile-command: "cd .. && make -k"
% End:

Wiki Compilers

Wiki compilers are great for those less blessed people who has an account in a web server but only with static pages( i.e University , Corporate Home pages). They work the same way a compiler works, produces ( actually compiles the wiki syntaxes into static html) offline contents of the static site beforehand.

Wiki Compilers

1. Wiko
2. ikiwiki
3. WikiWikiWftk!

I like the Wiko one a lot. See the creator's(Pau Arumi) page generated by this wiki engine. And the syntax is very similar to Wikipedia and Markdown.

Emacs-Muse
You can also use Emacs-Muse to manage a static web site. Alex Ott maintains a nice web site with Muse.

Markdown
This is the simplest approach, it just generates html from markdown files. Markdown syntax is very easy to work with, and it can readily convert simple text files to html files with footnotes, references, links, etc.

Org-Mode
Emacs' Org-mode can generate htmls (as well as lots of other formats, I use it to take my notes and generate technical documentation for softwares, it helps me to generate info/pdf/html/text documents from a single source. Very handy).

Save your emacs Fingers

To save my emacs fingers, I swapped all CTRL and ALT keys in the keyboard, and also mapped the CAPS LOCK key to the ALT.

Here is the xmodmap code in my Thinkpad T41p for swapping CTRL and ALT keys.

These keycodes are system-specific. Use `xev` to find out the keycodes in your system before applying this `xmodmap` script.

I just wanted to beat other boys

G. H. Hardy on his book A Mathematicians Apology:

I cannot remember ever having wanted to be anything but a mathematician. I suppose that it was always clear that my specific abilities lay that way, and it never occurred to me to question the verdict of my elders. I do not remember having felt, as a boy, any passion for mathematics, and such notions as I may have had of the career of a mathematician were far from a noble. I thought of mathematics in terms of examinations and scholarships: I wanted to beat other boys, and this seemed to be the way in which I could do so most decisively.

HaHa! I am better than you.

Stan Marsh to Butters Stoch on "You Got F'd in The A" in South Park

But that isn't the point, Butters!
The point is that this is now! It's
on! And there are people who need you
to step up! Look, nobody likes having
to rise to a challenge. But competing
against other people and getting in
their faces saying "Haha! I'm better
than you!" is part of life. And if you
can't face that, then you might as well
sit here and play Leggos until you're
an old man.

Excerpts from 10 Commandments

You shall not covet your neighbour’s house; you shall not covet your neighbour’s wife, or male or female slave, or ox, or donkey, or anything that belongs to your neighbour.
