When running a command like gf -make -name=T L_1.pgf ... L_n.pgf gf now checks if T.pgf exists and is up-to-date before reading and computing the union of the L_i.pgf files. The name (T) of the target PGF file has to be given explicitly for this to work, since otherwise the name is not known until the union has been computed. If the functions for reading PGF files and computing the union were lazier, this would not be necessary...
DESCRIPTION
The Grammatical Framework (=GF) is a grammar formalism based on type theory.
It consists of
* a special-purpose programming language
* a compiler of the language
* a generic grammar processor
The compiler reads GF grammars from user-provided files, and the
generic grammar processor performs various tasks with the grammars:
* generation
* parsing
* translation
* type checking
* computation
* paraphrasing
* random generation
* syntax editing
GF particularly addresses four aspects of grammars:
* multilinguality (parallel grammars for different languages)
* semantics (semantic conditions of well-formedness, semantic
properties of expressions)
* grammar engineering (modularity, abstractions, libraries)
* embeddability in programs written in other languages (C,C++,
Haskell, Java, JavaScript)
