Re: [racket-users] colorizing code in html - scribble or the GUI?

[Stephen Chang]

You can also submit the code to pasterack.org, which uses the scribble
css. Each paste page also gives the html source of the code and output
on the side, which you can copy to anywhere you want.

Re: [racket-users] Re: custom keybindings (AltGr)

[Matthew Flatt]

Thanks for looking into this problem in depth! Although I'll suggest an
alternate implementation, your patch was helpful for me to understand
the problems and goals.

To generate an event when AltGr- doesn't produce a character, I
think a better approach here is to call ToUnicode(). That seems to work
as a check for whether a meaning is assigned to a key combination. It
avoids using state to try to match key-up events with key-down events,
and it should work better with key repeats.

For making Ctl-Alt- work as AltGr-, I think I see what you want,
based on how programs like Notepad interpret key combinations. I think
other users will still want to distinguish Ctl-Alt- and AltGr-
for keyboard shortcuts, though, along the same lines that Emacs
distinguishes them. So we'll probably need to make that an option,
similar to the `special-option-key` setting for OS X.

Can you try the enclosed "key.rkt" to see whether it works the way you
want? This version defines `control+alt-always-as-altgr?` as #t to
simulate an option for making Ctl-Alt- work as AltGr-.

If you have Pygments installed, `pollen/unstable/pygments` and 
`pollen/template/html` can be used together to colorize code snippets (Racket 
or otherwise) & convert to HTML. (Your HTML page would also need a Pygments CSS 
file for the color theme.)

;
#lang at-exp racket
(require pollen/unstable/pygments pollen/template/html)

(->html @highlight['racket]{
 (define (foo x) (+ x 1))
})

(->html @highlight['python]{
 def foo(x):
 return x + 1
})

[racket-users] colorizing code in html - scribble or the GUI?

[Sanjeev Sharma]

is there a quick & dirty way to use scribble or the drracket GUI to generate 
html for random code snippets?
