Since the previous release: Machine::read_string() (the fs::path/std::string
overload pair split); kdesc -c and -u rendered from the ref/ reflection
klammerset; a fit column's tex width measured in TeX over every entry;
@typeface resolving to the family its css declares (a store directory name
now works in html) and hieroglyphs in @unicode_examples set in their
typeface; the ansi target -- plain text with the type styles a terminal can
show, identical to txt once the escape sequences are stripped -- with the
txt @table carrying :header_style, :style and :hline; @block anchoring,
@table spacing and the Image_quality state variable; and the rewritten
doc/klammertext_for_llm.md.
A character written in the ^...^ mnemonic form -- ^oe^, ^zz^, ^hello^ --
used to kill ktext outright: no message, no output, and an exit status
that looked like a crash because it was one. Only the forms that happen
to spell hexadecimal digits escaped, and they were right by luck rather
than by reading. Any caret form that names no character is now a located
error that quotes what was written.
A klammer may now sit inside square brackets and braces as it already
could inside parentheses, and may be followed by the punctuation that
ends a sentence: [@i word@], {@b word@}, @i word@'s. The rule is a fixed
list of characters, because none of them can occur inside a klammer name
and so none of them is ambiguous next to a delimiter. A letter still
cannot: "x@" is the named closing delimiter, so a letter before "@" has
two readings and no rule can separate them.
The abbreviations an author writes -- the hyphen form @i-word, a klammer
glued to its neighbouring punctuation -- are now recognised as author
conveniences only. They are not applied to @@ definitions or @@@ system
commands, which are written by someone who needs no such shorthand and
whose forms are already whole.
Also fixed, each of them silent: an exported shell function in the
environment broke every @eval in the document; a line break written with
@nl was destroyed when it passed through a klammer that generates a
table, printing as \textbackslash{}newline in the finished PDF; and
"kdesc --coverage" shortened its file column by comparing the spelling of
a path rather than the path, so a klammer set reached by a symbolic link
showed a full path where its neighbours showed a short one.
New in the distribution: ref/, a small klammerset that describes the
Klammermachine's own tables in Klammertext. It currently provides the
character tables -- the diacritics and the extended Latin letters -- as
klammers that render to any target, so the documentation of what can be
written cannot drift from what the machine accepts. It is early, and
will grow.
The Klammertext taxonomy now has a section on targets, describes the
@@@klammerset system command alongside the other three, and states the
precedence of "^" -- what a caret means before a letter, a digit, a
punctuation character, and a quote, in one ordered list.

A @table now renders to txt. What it needed settled how plain text sets
a block off from the prose around it, which is by INDENTING it: that is
the only structural device the medium has, where html and LaTeX have
boxes, rules and space. An indented block is one that has already been
laid out, and the target leaves its lines alone.
A caption is placed above a table or a listing and below a figure, in
every target rather than only in plain text. A figure is taken in at a
glance, and the caption then names what the reader has already seen; a
table is read, and a reader who meets the rows before the subject has to
read them twice.
Also fixed, all three of them silent: an indented paragraph was dropped
from plain-text output rather than left as written; an @indent block was
re-flowed, so the indentation of its later lines appeared as gaps in the
middle of a line; and a table captioned with ":number false" lost the
rule under its caption, while an unnumbered table wrongly consumed a
number that a reader counting captions would then find missing.
(from dev 8173c371bba6)
A run of Unicode code points now needs one pair of carets, not one pair
each: ^9053 53EF 9053^ renders the characters adjacently, and a single
character inside such a run stands for itself. An invalid code point is
an error naming the position that wrote it, rather than an apology
rendered into the finished document; noncharacters are refused alongside
surrogates; and a code point that lands on a Klammertext special is safe
through the re-reads that assemble a document. The character tables now
produce the precomposed form, so a diacritic written as ^a" and one typed
directly are the same text to a search or a copy-paste.
"kdesc -u" describes how to write a Unicode character, with tables of
glyphs beside the codes that produce them. It is new and not yet
complete: it predates the sequence form and the typeface klammer below.
A typeface and a style are no longer both called "font". A typeface is a
family resolved by name; a style code is the one letter naming a type
style. So @document takes :serif_typeface and its siblings, a table takes
:style, captions take :caption_style and :caption_size, the uniform scale
is :text_scale, and the command is "kdesc --typeface". This renames
arguments a document may already use; an old name is a located error
rather than a silent omission.
@typeface sets a passage in another typeface for the length of that
passage:
@typeface Noto Sans Egyptian Hieroglyphs | ^132AA 133CF^ :scale 1.5 @
Writing the klammer is the whole declaration -- the document resolves the
typeface, embeds it in what it produces, and carries its license along.
Two typefaces for scripts no text font covers now ship with Klammertext:
Noto Sans Egyptian Hieroglyphs and Noto Sans Cuneiform. Every typeface in
the distribution now carries its license file.
(from dev 61e598698891)
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.
@@caption_args.o :caption :number.bool true :caption_side.side
: Arguments that define a caption for a block element @@
@@code.k :filename @hpos_args :hpos left @ @caption_args :caption_side top @
| text.literal : A source file displayed verbatim @@
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)
An optional argument has three values: the default (the name is absent),
the argument type's :alone value (the name is written alone), and a
written value.
:alone is declared by the argument type only, never by a klammer's
parameter declaration -- a default is what one klammer means by silence,
but a bare option name must read the same way in every klammer. The bool
type declares :alone true, which is the whole of the convention that a
bare boolean option means true; there is no boolean special case in the
engine. A type whose pattern matches running text cannot declare :alone,
since an option's value runs to the next bar or option name and would
swallow the following text.
kdesc and `ktext -m` now show [default: X] and [alone: Y] per argument
type.
In the Standard Klammer Set: @code :number becomes a bool (it was an
untyped string tested only for truthiness, so a bare :number was a
no-op); decimal_mark declares :alone comma; table_hline and table_vline
declare :alone all. The 35 bools that default false gained the bare form
for free.
Tests: tst/alone_test.sh (21 cases) joins the shipped suite.
(from dev 6024f49c2859)
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'.
