A klammer that reaches itself, directly or through a cycle, expanded until the C++ stack was exhausted: the process died from SIGSEGV with no message and no location. The former limit guarded only the top-level fixed-point iteration, never the descent through klammer application. A depth guard now raises a recursion error naming the klammer and where it was applied. The same loop's termination test moves from "the katom list stopped growing" to "a pass applied no klammer", since a klammer whose body expands to nothing is a reduction that adds no katoms; exceeding the round limit is now an error rather than a message followed by rendering a document with live klammers still in it. ktext --check locates every klammer application written in a document or in a klammer body and checks name existence, argument count, option names, and target coverage without applying anything, reporting all problems at once. This is possible because Klammertext has no catcodes: katom structure is fixed when a file is read, so a klammer body has a determinate shape before it is expanded. The check therefore reaches what the engine cannot -- the branch of a @cond that is not selected, and bodies a given render never enters. @cond's set of truth values is an open language question, so its meaning is unchanged here; an unrecognized predicate now warns, giving its value and location. tst/ gains recursion_test.sh (7 cases) and check_test.sh (19 cases), and this snapshot's test Makefile is generated from the shipped suite list so the two cannot drift apart.

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 c27e63802406.
