NAME
calculus - algebraic type system tool
SYNOPSIS
calculus [ options ] input-file ... [ output ]
DESCRIPTION
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.
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.
