% colitur wall calendar -- A4 landscape, one month per page. flavour: latex
% Build: colitur table --year 2027 --template grid.tex > grid.tex && pdflatex grid.tex
% This template has no table of contents and no cross-references (unlike
% ordo.tex), so a single pdflatex pass is enough -- there is nothing for a
% second pass to resolve.
%
% The grid must FILL the page, not sit in its top quarter: \arraystretch
% alone only pads a row's NATURAL height, it cannot make a table taller
% than its own content wants to be, which is exactly why the previous
% version floated at the top with the rest of the page blank. The fix is
% to compute an explicit row height from the text height itself (\cellh
% below) and give every cell a fixed-height parbox of that size, so the
% table's total height is dictated by the page, not by its content. Every
% month in the 1583-9999 domain has either 5 or 6 Sunday-started weeks
% (never fewer), so dividing the available height by 6 fills at least 5/6
% of it on a 5-week month and all of it on a 6-week one -- never a quarter.
%
% Real names, not slugs: the observed day's own display name is a PLAIN
% resolved string (View.of_days, Task 5), interpolated directly as a plain
% var below -- there is no dotted-la-with-slug-fallback idiom left to
% write (see ordo.tex's own header comment for the full reasoning; it
% applies here unchanged).
%
% The weekday header row comes from the view's top-level weekday_headings
% list (name/last objects), not a hard-coded "Dom Lun Mar" row: the engine
% rejects an EMPTY tag path -- a bare dot inside a section, on its own --
% as a parse error, so the loop below must name a field on each heading
% object rather than interpolate the section's own value directly, and a
% hard-coded row would not be localised anyway. Every cell (day and
% heading alike) also carries a last flag, true on the seventh of its row:
% a LaTeX table row needs the ampersand separator BETWEEN cells, not after
% the last one, and the engine has no unless-last construct, so the flag
% is data -- rendered only when NOT last. A trailing ampersand gives eight
% columns for seven cells and pdflatex rejects the file outright.
