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)
Klammertext
Klammertext is a markup language that produces multiple output formats — HTML, LaTeX/PDF, and plain text — from a single source description. Its core engine, the Klammermachine, is written in C++; the Standard Klammer Set (SKS) adds a default library of formatting and document-structuring operators on top.
Installing
Installation guides are in doc/install/:
- Linux, from source —
doc/install/linux_source_install.md - macOS, from source —
doc/install/macos_source_install.md - Linux, container —
doc/install/linux_container_install.md - macOS, container —
doc/install/macos_container_install.md
Building from source
With a C++20 compiler and KLAMMERTEXT_HOME set to this directory:
make -C com
This builds the Klammermachine library (into lib/), the SKS components, and
the three commands — ktext, kdesc, kdiag (into bin/). See the
source-install guide for prerequisites (TeX Live for PDF output, Python, and so
on).
Editor support
Editing support for Emacs, Sublime Text, Vim, and Visual Studio Code —
syntax highlighting, delimiter matching, structural reindentation, table
alignment, diagnostics — is in doc/edit/, together with the
shared implementation and the Klammertext language server they build on.
Provenance
This repository is a curated snapshot of Klammertext's private development tree, assembled by a manifest-driven script. Its history is a series of release snapshots, not a mirror of the development history, and files here are regenerated on each release — patches cannot be merged directly. Report problems (or send patches) to the author; accepted changes are applied to the development tree and appear in a following snapshot.
This snapshot was assembled from development commit 6024f49c2859.
