A snapshot of the development tree. The substantial changes since the last one:
COMMAND OUTPUT POLICY. The three commands display text in exactly three cases,
and each owns a stream: LOGGING under "-v" greater than 0 and an ERROR before
termination go to STDERR; OUTPUT THE USER ASKED FOR goes to STDOUT. For ktext
that output is a document, so "ktext doc.kt -d | ..." is now safe -- logging
used to share the stream and land inside the document. A bare command prints
its usage and succeeds rather than failing. Colour is emitted only to a
terminal, per stream, and NO_COLOR is honoured.
"-v 1" reports every decision whose outcome you could not have read off your own
input: the klammerset that was loaded and from which file, a font's directory, a
":files" name's file, how "-o" was expanded. Higher levels are the trace.
The commands no longer warn and continue: an anomaly is an error, described with
its location. Two exceptions remain, each for a stated reason -- a condition
that is expected and temporary by design, and a judgment that is a heuristic
rather than exact.
@cond IS NOW A TRUE SPECIAL FORM, resolved at APPLICATION time rather than when
the file is read. Two consequences for a writer:
* a state variable reaches the predicate. "@@@state Flag :value true @@@
@cond *Flag* | T | F @" renders "T"; it used to see the literal "*Flag*" and
silently take the false branch. The document now behaves like a klammer
body, whose arguments are bound before its conditionals are decided.
* nothing in a discarded branch happens -- it is not read, not evaluated, not
expanded. An @eval in the branch not taken used to run anyway.
Its predicate relation is total and strict: true, True, 1; false, False, 0, and
empty; anything else is an error at the @cond rather than silently false.
@eval REACHING OUTSIDE. ":shell" and ":haskell" now keep the command's standard
error out of the document (it appears under "-v 1") and treat a nonzero exit as
an error naming what the command reported. A command that exits nonzero on
purpose -- "grep" finding no match -- says so with "|| true".
KLAMMER SETS. Several combine: "--klammersets a b c" loads all three in the
order given, sharing one namespace, with the definition modes deciding
collisions. "none" means none and may not be combined with other symbols. A
klammerset with symbol X is declared in a file X/X.k, which is what lets two
sets require the same third set without loading it twice.
TESTS. Four new suites: the kdiag command's interface, the @eval primitive's
contract with the outside world, and verbosity at both tiers. Three suites
that could not run on macOS at all now do.
Assembled from dev commit 6c8ee6c22fca.
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)
The four defaulted parameters in html_util.h stayed by-value while the
definition became const&, leaving the called overload undefined.
Linux's -shared linking hid it (lazy dlopen resolution); it broke the
book-structure HTML path at runtime. Both sides now agree (const&,
defaults kept); combine_files converted consistently as well.
(from dev a910e11431d2)
The @@@klammerset system command formally declares a klammerset — a
named, logically related group of klammer definitions — with an
operative, idempotent declaration (:requires and :files load in order
at the declaration point, relative to the declaring file). A bare
symbol given to ktext -k, kdesc --input, or :requires resolves to
x/x.k on the search path: the document's directory, then
KLAMMERTEXT_KLAMMERSETS, then KLAMMERTEXT_HOME; kdesc --klammerset
lists the available sets. sks/sks.k is the first declared klammerset,
so `-k sks` loads the SKS by name. The engine's lookup classes were
renamed *_set → *_registry to keep the two concepts apart, and the
whole C++ tree now follows standard const-correctness conventions.
tst/ gains klammerset_test.sh (18 cases).
(from dev 64b1abf23e56)
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'.
