I am not on a machine with latest context (and cannot update right now). The code above was taken from catc-ini.mkiv, but that file changed in the latest update. Could you please run the following test and see if it works: 1. Copy t-module-catcodes.tex to your local directory. 2. Change \gdef\activetabtoken{^^M} with \xdef\activetabtoken {\Uchar\tabasciicode } and similar for other \gdef's according to lines 121-124 of https://github.com/contextgarden/context-mirror/blob/25fcad7435f56cdce265833... and run your test again. Thank you for the report. Aditya

Now, as you're not afraid of low level code:
\unprotect
\unexpanded\def\StartAditya {\buff_pickup {Aditya}% {StartAditya}% {StopAditya}% {}% {\savebuffer[file=test-temp.tmp,prefix=no,list=Aditya]}% \zerocount}
This is perfect as I am already using `\grabbufferdata` in my code. I can easily adapt it to use `\buff_pickup` instead. Thanks!.
Does what you want but of course it's sort of ugly for a module to do that. What we can do is this which is still ugly but picking up verbatim is always ugly:
\def\buff_start_indeed#1#2#3#4% {\edef\p_strip{\namedbufferparameter{#1}\c!strip}%
\normalexpanded{\buff_pickup{#2}{#3}{#4}{}{\buff_stop{#4}}\ifx\p_strip\v!no\zerocount\else\plusone\fi}}
\protect
I want this to be configurable at runtime and the vim module already has code that enables `strip=yes` and `strip=no` options (I do this via a function in vim so that it works with both mkii and mkiv; although I don't think that anyone uses the mkii module any longer). Aditya

I added `strip=yes` option to the filter module, which is now the default option. See "Stripping leading whitespace" in the module documentation (https://github.com/adityam/filter). This is a MkIV only feature and I will not implement it in MkII. I also made `strip=yes` to be the default in t-vim (to be consistent with t-filter). In t-vim, the `strip` option works with both mkii and mkiv. Aditya
