how to start a keymap project

I have take a try dvorak keyboard layout, and i also taked a look of programmers dvorak and colemak layout. But what I'd like create a new layout, which is more better in code and *nix.

I've do some statistic from many codes include java,python,ruby,php,c,js, and get a result of which key use most, which symbol use most, which number use most.

The keyboard will be totally shuffled.

_ and - should be seprate, = should get a good postion, {} should not in shift place....

the numbers key's frequency is not equals, 0 is most , then 1, 2, 3 , 4 , 5, 6 , and 9 ,8 ,7 is rarely use, i开发者_开发知识库t will be move into shift place, ...

and also many change with letters, e,t is use most, some sequence like re, er, es, se, also be use most, I put them together "RES", ...

it is diffrent with dvorak and colemak, what i want is not only a Xmodmap file, I want a keymap project. Before this, I have some question.

1. setxkbmap us -v colemak, what's the meaning? colemak is a variable of us layout? but dvorak is "setxkbmap dvorak" ,what's the diffrent.

2. if I wrote a linux keymap file , should I wrote an Xorg keymap file again in diffrent format? if true, where can I find the Xorg keymap file in archlinux?

3. I am using archlinux, is the keymap file the same between with diffrent linux distribution and unix and *bsd system?

4. where can I found some useful documentation?

here is a link to keyboard layout optimiser it allows you to "evaluate" your layout using the text files you want. You might also find some usefull links on it.

Information on X keyboard layout files can be found at:

• xkb-config project
• XKB information from X.Org

Xkb configuration files are standard across all flavors of Linux and Unix, though their installation location varies. Most modern distros install them under /usr/share/X11/xkb/ now.

In a standard Linux distribution, you should find the "USA Programer Dvorak" layout. It is not as shuffled as you described, but has good ideas.

I tend to prefer using standard layout over personalized layouts. It is always difficult when using several machines to deploy on all of them (@home, @work ...). You always find yourself missing your super-magic-fantastic keymap. (This is the reason that drives me to standard dvorak instead of own mapping, that drives me to use vim instead of nedit, ...)
