Undefined control sequence
why are special catcodes needed? an dif so, there are often easier ways
than low level hacking
This is the commit (from 2011!) where I added this code:
https://github.com/adityam/filter/commit/c34023fd1ede0909a056a10c6352202f2295fba4
My guess is that I did not want multiple newlines to collapse in t-vim, so
I had redefined \activeendoflinetoken to {\strut\par}. The offending lines
are copied from catc-ini.mkiv from the same time:
https://github.com/contextgarden/context-mirror/blob/5056d7a854142aa63032b0a3ca4d41c496e41faf/tex/context/base/catc-ini.mkiv
to make sure that I use the same syntax for MkII and MkIV.
A couple of years after that I split the MkII and MkIV code into separate
files, but I never touched the catcode part (because it was working).
I cannot test the latest beta right now; I'll test it on Monday. In the
meanwhile, what is the current recommended method to alter the way literal
newlines and tabs are shown.
\starttext
\start
\def\obeyedline{\blank[line]} \obeylines
line 1
line 2
line 3
\stop
\stoptext
blank will cleanup for you
I don't want multiple empty lines to collapse (this is for code listing).
Here is a minimal example showing what t-vim is doing:
\newcatcodetable \MinimalCatcodes
\startcatcodetable \MinimalCatcodes % for reading t-vim output
\catcode\backslashasciicode = \escapecatcode
\catcode\leftbraceasciicode = \begingroupcatcode
\catcode\rightbraceasciicode = \endgroupcatcode
\catcode\endoflineasciicode = \activecatcode
\catcode\formfeedasciicode = \othercatcode
\catcode\spaceasciicode = \othercatcode
\stopcatcodetable
\starttext
\bgroup
\def\obeyedline{\strut\par}
%\def\obeyedline{\blank[line]}
\setcatcodetable\MinimalCatcodes\letcharcode\endoflineasciicode\obeyedline
This is a \color[red]{test}
To check multiple lines as well as color
\egroup
\stoptext
If I replace the {\strut\par} with {\blank[line]}, multiple empty lines
are collapsed to a single line.
