How to customize the default verbatim colors

How to customize the default verbatim colors

[Eugene Toporov]

[-- Attachment #1.1: Type: text/plain, Size: 786 bytes --]

Hi all!

I recently started using Verbatim Macroses to make source code pieces look 
prettier in my docs.
I use things like \setuptyping[JV] and then \startJV - \stopJV

But I'd like to change the default colors in the macroses to my own.

I only found that redefining some colors like this 
\definecolor [colorprettyone] [green]
\definecolor [colorprettytwo] [navy] 
\definecolor [colorprettythree] [r=0,g=0,b=.9]

makes effect, but that seems not very effective and affects all verbatims. 
1) I could not find all colors.
2) I need several different schemes (palettes) for different verbatims (XML, 
Java, SQL). 

I expect there is a way to redefine whole palette or something.

What's the easiest and the right way to do it?

Thanks in advance!

Unable to make cont-en.fmt

[luigi.scarso]

Hi, while installing latest pdftex 1.30.1 I have messed with some 
configs files
and now I am unable to remade format.
So
$> fmtutil --byfmt cont-en
gives

running `pdfetex -ini   -jobname=cont-en -progname=context -8bit 
*cont-en.ini' ...
This is pdfTeXk, Version 3.141592-1.30.1 (Web2C 7.5.5) (INITEX)
 %&-line parsing enabled.
! I can't find file `*cont-en.ini'.
<*> *cont-en.ini
               
Please type another input file name:
! Emergency stop.
<*> *cont-en.ini
               
No pages of output.
Transcript written on cont-en.log.
Error: `pdfetex -ini  -jobname=cont-en -progname=context -8bit 
*cont-en.ini' failed

###############################################################################
fmtutil: Error! Not all formats have been built successfully.
Visit the log files in directory

###############################################################################

This is a summary of all `failed' messages and warnings:
`pdfetex -ini  -jobname=cont-en -progname=context -8bit *cont-en.ini' failed

In file fmtutil.cnf there is the correct line :
cont-en pdfetex         cont-usr.tex    -8bit *cont-en.ini
(instead
cont-en pdfetex         cont-usr.tex    -8bit  cont-en.ini
works )

I have cont-en.ini in
$>kpsewhere cont-en.ini
/usr3/TeX/texmf-dist/tex/context/config/cont-en.ini

Any ideas ?

thanks
luigi

Luigi,

It attempts to read the file "*cont-en.ini", with the star included
in the name. From personal experience, I know that this will happen
when pdfetex is not really pdfetex, but a non-etex pdftex ...
(because of a symlinked executable, i'll wager)

symlink it's the magic word...
Yes, the error happened when I copied latest pdfetex and pdftex:
pdftex is symbolic link to pdfetex.
I was so stupid to remade copy until i didn't read your answer...

Now all it's ok.

Many thanks Taco

PS:
What do you think about to write a dense guide to programmer on how to add
a pdftex primitive (something like \pdfhelloworld) and how to interface 
to an
external libray (like zlib) ?
I think that this will fill a hole in documentations.

Hi,

try
   pdfetex -ini   -jobname=cont-en -progname=context -8bit cont-en.ini
I think now etex does not want stared files. If so, change your fmtutil.cnf

Like I said: From personal experience :)

It goes roughly like this:

* create pdfetex-main.web from all of the web and change files so you
   have a least a sane source while coding, and make a copy for future
   comparison
* find an existing command who's syntax/semantics are close to the
   one you intend to implement ("extension" is fairly useless for
   anything that actually does have an impact on typesetting, you
   probably want 'convert' or 'last_item').
* hook a new subcode into the processing of that existing command,
* add a call to primitive()
* create a code line to print_cmd_chr()
* when it builds ok, create a change file by running diff on the
   original pdfetex-main.web, and add this change file at the end
   of the change file list in pdfetex.mk

I'll see if it is possible to create a document with a bit more specific
info

Yes, sure (you need to define an XXXcolorpretty palet for each type
you want to change):

   \definecolor[MYcolorone]  [r=.8,g=.5,b=.5]
   \definecolor[MYcolortwo]  [r=.8,g=.5,b=.2]
   \definecolor[MYcolorthree][r=.8,g=.5,b=.8]
   \definecolor[MYcolorfour] [r=.8,g=.2,b=.5]

   \definepalet[MYcolors]
     [  prettyone=MYcolorone,
        prettytwo=MYcolortwo,
      prettythree=MYcolorthree,
       prettyfour=MYcolorfour]

   \definepalet[XMLcolorpretty] [MYcolors] % the name is magic !

   \setupcolors[state=start]
   \setuptyping[option=color]

   \starttext
   \startXML ... \stopXML
   \stoptext

Cheers, Taco

Thanks a lot, Taco!

I knew there should be a good way!
Maybe it would be useful to add it to http://contextgarden.net/Verbatim_text?

I also noticed that XML verbatim does not correctly handle tags with 
namespace.
In the xml like <ns:tag attribute="somevalue"> the "ns" gets colored with 
tag-color, the "tag" with attr-color. I think the whole "ns:tag" should be 
of tag-color.

Best wishes,
Eugene

Be my guest ;-)

How about this?

   %% allows XML tag names to continue after colons (namespaces)
   \input verb-xml % TRICK
   \appended\gdef\XMLsetspecials{\setpretty`\:=10 }

   \starttext
   \startXML
     <ns:tag attribute="somevalue" />
   \stopXML
   \stoptext
   %%

You can use  \setpretty`\:=17 instead, if you want the colon to be
indistinguisable from the rest of the tag.

The line I've marked 'TRICK' is needed to make sure that the original
definition of \XMLsetspecials is loaded before the new addition takes
place (verbatim definitions are loaded runtime).

Cheers, Taco
