kdesc gains --coverage, which reports for every klammer the set of targets it
can render to, and — the point of it — which klammers' coverage cannot be
derived and must therefore be declared. Three rules: coverage is DERIVED
where the definitions determine it (a general body of klammer calls covers
the intersection of what those klammers cover, by a greatest fixpoint after
loading), DECLARED where the engine cannot interpret what decides it (an
@eval body, whose targets are undecidable), and UNKNOWN where nothing is
written — which never means "deliberately unavailable".
Two new spellings in a definition's name. A comma-separated target list,
"@@table.html,tex :: ...", gives one body several targets; it is surface
syntax, expanded at registration, and each member goes through the
redefinition rules on its own. And "@@date.* :: ..." writes the general
target out, asserting that the klammer works for EVERY target including ones
not yet defined — a stronger claim than a list of the targets defined today,
and the one target declaration that could be mechanically falsified.
The Standard Klammer Set was swept accordingly: it now has no general
definitions at all, every klammer names the targets it serves, six use ".*",
and tex and pdf are at zero undecided.
kdesc's flags are reorganised on two rules: a flag reached for often gets a
single letter (-k klammers, -t targets, -c characters, -i input), a more
specialised topic a multi-letter name (--argtypes, --katoms, --rewrite,
--optionsets, --coverage, --klammerset, --font); and -v says how much to show
about PROCESSING, never what the RESULT contains — so the katom regex column
is "--katoms full" and the coverage detail "--coverage all". NOTE: "-k" now
lists klammers (optionally filtered by a name/description search); the katom
table moved to "--katoms".
Fixes carried along: an option written with no value crashed the command with
SIGSEGV instead of reporting the mistake; two required positional arguments
never parsed; kdesc and kdiag printed an error and exited 0; and definition
diagnostics counted registrations rather than what was written, so one line
could be reported as two definitions and then printed twice.
Four new test suites: target_list, coverage, command_option, kdesc.
(from dev 46f54080bd9a)
A named group of optional parameters, declared once and used by several
klammers, so a writer learns one vocabulary instead of a spelling per
klammer. The "o" target is a pseudo-target beside "k": "k" declares a
klammer's interface and documents it, "o" declares an option interface and
documents it, and neither produces output for any target.

A set is used only in the parameter list of a ".k" declaration -- the one
place a klammer's interface is declared once for all of its targets -- and
is resolved as that list is read. Names and types come from the set; a
default may be overridden where it is used. A klammer application in a
parameter list is now a definition-time error.
The SKS gains the sets caption_args and hpos_args (:hpos and :offset), and
@table, @image, @image_grid, @reference and @show gain .k declarations. A
distance is no longer written as a position: :hpos 4em is rejected, and the
same layout is :hpos left :offset 4em. Code listings are numbered by
default, like tables and figures.
New engine sources mac/option_set{,_registry}.{h,cpp}; tst/ ships two more
suites, option_set_test.sh and signature_test.sh (twelve in all).
(from dev 34e536cb0329)
Quoted Klammertext specials (^@ ^| ^# ^^ ^: ^*) and ^'...'^ regions now
survive re-processing (held as escape markers until final output);
:after_apply phase functions receive and return raw target text.
Tables: :hpos element position (center|left|right|<length>) replaces the
unimplemented :center/:indent; the ranged cell override is renamed
:justify; :column_width works in html (colgroup widths) and gains
'fill' -- the remaining width, capped at the column's widest entry, in
both targets; a table wider than the text column warns on the console;
table edges without an outer line set their text flush on the margins.
@document: no empty title bar for untitled documents; @vfill fills to
the bottom of the window in html (pure CSS); @vspace in plain text;
new @dot klammer; monospace email links.
- @table: a writer's :hline/:vline replaces the default lines; new
boundary name 'none' removes all lines
- @table: ranged :hpos argument overrides :cell_hpos per cell
(\multicolumn{1} in tex; positions a colspan anchor's merged cell)
- @date/@datetime: :days offset argument (sks/date/date.py)
- @document: ":bottom none" suppresses the footer (\pagestyle{empty})
Also carries the escape-system generator/renderer fixes, per-cell-range
:format, and uppercase .TTF/.OTF font recognition from klammertext-dev.
Sync with klammertext-dev through b90b0e09:
- Argument types end to end: :python_cast values are applied (Python
@eval receives real bools/numbers/lists), argument values are
validated against their argtype patterns with the argtype's
description as the error message, argtypes can declare :default
(overridable per declaration), and parameterized type families are
supported: rest(N) casts a rest argument to an N-dimensional list
(bar-count = dimension).
- Unified indexed_range syntax (selector with parenthesized subsets,
composable mnemonic names) for table lines and spans.
- Table klammer: caption fonts fixed in both targets, :column_width /
:leading / :colsep wired, :colspan and :rowspan render (HTML
attributes; \multicolumn / \multirow), calculated cell values (:calc)
with prefix operators, display-precision semantics, :calc_format and
:decimal period|comma.
- Fonts: closed-world resolution on the Klammertext font store
(infrastructure in mac/font_store; no Google Fonts links or fetch).
Default fonts live in the top-level fnt/; additional fonts install
into KLAMMERTEXT_FONTS directories via kdesc --font (list, samples,
preview, install — classification by font metadata). CSS font family
names are quoted (digit-initial families were silently lost).
- Environment files moved from mac/env/ to the top-level env/; shell
profiles source env/runtime.env. Dead per-host variants removed.
- Container: fnt/ ships in the image; curl removed (no network use).
Curated source subset assembled by klammertext-dev's doc/make_dist.sh: the Klammermachine (mac), the Standard Klammer Set (sks), the commands (com), editor plugins and install guides (doc), a test subset (tst), and lib/bin placeholders. Builds with 'make -C com'.
