Trouble with percent character in ConTeXt text (programm code typing)

Trouble with percent character in ConTeXt text (programm code typing)

[Jaroslav Hajtmar]

Hello all...

I am converting any manual from HTML to ConTeXt.
There are a lot of programm code. and in the code is very often % 
character.
Ther is no problem in \startyping - \stoptyping environment, but I need 
using this in text ... for example

The sequence \type{%0} stands for the whole match. The sequence 
\type{%%} stands for a single~\type{%}.
or
For instance, the call \type{string.format('%q', 'a string with "quotes" 
and \n new line')} will produce the string:
...
etc..

1.

It is clear that this can not work, but is there any satisfactory solution??
Something like \startypingintext  ...  \stoptypingintext  i.e. intext 
typing environment..


2.
in html code is often emphasis found inside the program code
for example:
<code>\<em>ddd</em></code>,

Maybe it's a dumb question, but may be inside emphasis inside verbatim 
(\startyping - \stoptyping) environment??

Thanx Jaroslav

What prevents you from testting this yourself, \type{%} produce a '%' in 
the text.

Yes, it's possible to use style commands in verbatim mode but the 
mechanism in MkII and MkIV
are different and it's important to know which system you use.

project, not my minimal example... I found error in code on the same row..

Thank you to help and sorry...

Hello, all

Why is a problem with character # inside TABLE??

It works:
\bTABLE
\bTR
\bTD \type{\#patt}\eTD
\eTR
\eTABLE


Isnt works:
\bTABLE
\bTR
\bTD \type{#patt}\eTD

the next version will have \asciimode which will make all those chars 
regular characters (apart from % \ { })

Re: Trouble with # character in TABLE environment...& trouble with \starttyping environment too

[Jaroslav Hajtmar]

Ok. Thanx Hans.
I solve it with \#\type{patt} it look like as have it and therefore isnt 
problem.

BUT now I have problem with \starttyping - \stoptyping environment too.

here is example:

This works OK...

\starttyping
c = re.compile([[
   longstring <- ('[' {:eq: '='* :} '[' <close>) => void
   close <- ']' =eq ']' / . <close>
]], {void = function () return true end})

\stoptyping


But when I add last row, then stop work and get error message:

\starttyping
c = re.compile([[
   longstring <- ('[' {:eq: '='* :} '[' <close>) => void
   close <- ']' =eq ']' / . <close>
]], {void = function () return true end})

print(c:match'[==[]]===]]]]==]===[]')   --> 17
\stoptyping


Message error surprised me:

systems         : begin file lpeg.tex at line 32
! LuaTeX error <main ctx instance>:7: ')' expected (to close '(' at line 
1) near
  ']'.
\dododowithbuffer ...!!bs \detokenize {#1}\!!es )}
                                                    \dododowithbuffer 
\nododo...
l.46 \stoptyping

What system controlling inside \starttyping \ stoptyping environment?

Thanx Jaroslav

mkiv happens to use === itself so either change your example to use 4 
='s or adapt this:

\unprotect
     \def\!!bs{[=====[}
     \def\!!es{]=====]}
\protect

(i might even move to == instead of === as it's saves tokens)

Thanx Hans,

I did not think that inside \starttyping -- \stoptyping environment 
ConTeXt could do such a check this thing.

Thanks so much. Health Jaroslav

Well, the captured content is passed to the lua end using long strings 
so nothing is processed at that stage.

Of course I could parse for embedded long strings but that a bit over 
the top I think.

Is there a more robust way to do this? Perhaps making the number of equal 
signs user configurable?

redefining \!!bs and \!!es is ok as they will not disappear

after all, how often does one use [===[ and ]===] in lua code (in a non 
symmetrical way).

debatable but it's a comment

things like this can be discussed extensively at the upcoming context 
meeting
