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:

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.

\def\obeyedline{\blank[line]} \obeylines

line 1

line 2

line 3



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

This is a \color[red]{test}

To check multiple lines as well as color

If I replace the {\strut\par} with {\blank[line]}, multiple empty lines are collapsed to a single line.
