calculus - algebraic type system tool
calculus [ options ] input-file ... [ output ]
calculus translates a specification of an algebraic type system, input- file, into code representing that system. This takes the form of a number of files which are generated in the output directory, output. If no output directory is specified then the current working directory is used. Input files and command-line options may be given in any order. Options always relate to the input files immediately following. By default, C code implementing the type system is generated, however this may be changed by means of command-line options.
-Aname Specifies that the algebra named name should be used by the output routines. Unless otherwise specified the last algebra input is used for output. -Efile Specifies a file containing a list of extra types to calculus. These are used, for example, to generate extra disk reading and writing routines in conjunction with the -d option. -Tfile Specifies a template file which is used to generate an output file output. -a Causes calculus to generate extra statements in its C code which includes assertions about null pointers etc. and other code to help in writing programs using the tool. -d Causes calculus to generate disk reading and writing routines designed to add persistence to the generated type system. -i Indicates to calculus that input is a simple input file. -o Causes calculus to output a pretty-print of the input algebra into output, which in this instance in an output file. If no output file is given then the standard output is used. -p Causes calculus to generate printing routines designed for use in the debugging of programs written using the type system. -r Indicates to calculus that input is the output of a previous -w option. -t Causes calculus to generate #pragma token commands describing the type system. These are designed so that tcc(1) can apply extremely rigorous type checking to programs written using the type system. -v Causes calculus print its version number. -w Causes calculus to output a dump of the input algebra into output, which in this instance is an output file. -x Causes calculus to suppress the vector and vector pointer constructs in its output.
