Hi,

I'd like to have my \startlines ... \stoplines indented in the following way: the first two lines unindented, the next two indented, and so on. Basically, this means that I'd like the pattern to be based on (mod 4) arithmetic and not (mod 2). Is it possible? If yes, how?

OK, so I thought I can handle this... but not:(.

I found the relevant definitions in spac-hor.mkiv and tried to add a line saying

\installindentingmethod \v!evenpairs{\c_spac_indentation_toggle_state\plusfour}

% there is no \v!evenpairs

\unprotect

% english interface only:

\installindentingmethod {evenpairs} {\c_spac_indentation_toggle_state\plusfour}

% or maybe:

\installindentingmethod \v!quadruple {\c_spac_indentation_toggle_state\plusfour}

% as \v!quadruple is a known keyword

\protect

Sorry to say that, but neither seems to work... ! Missing number, treated as zero. <to be read again> q \v_spac_indentation_current ->q uadruple \4>unknown #1#2#3#4#5->#2=#1 \relax \spac_indentation_apply_step_one ...on_setup_size \fi \next1 #1,->\spac_indentation_apply_step_one {#1} \syst_helpers_do_process_co... \syst_helpers_do_process_comma_list ...rgument #1, ]\relax \global \advance \... ... l.36 \startlines[indenting=quadruple] ? What do I do? (And what do I do if I really want "evenpairs", especially that I'd like to have "oddpairs", too, so "quadruple" is not really a good keyword for me?)

it is hard to say what goes wrong if you only show the error message and no real code

Sorry for that, my fault. Now comes the fun part: I *copied* my code from "my" version of spac-hor.mkiv to the document, and it started to work then! Strange. I attach a MWE. Hans, is it possible to add something like that to spac-hor.mkiv?
