NAME
icont - translate Icon program
SYNOPSIS
icont [ option ... ] file ... [ -x arg ... ]
DESCRIPTION
Icont translates and links programs written in the Icon language.
Translation produces ucode files, suffixed .u1 and .u2,
which are linked to produce executable files.
Icon executables are shell scripts containing binary data; this data is
interpreted by iconx, which must be present at execution time.
File names ending in .icn are Icon source files;
the .icn suffix may be omitted from command arguments.
An argument of - reads from standard input.
A name ending in .u, .u1, or .u2 selects both files
of a ucode pair.
The specified files are combined to produce a single program,
which is named by removing the suffix from the first input file.
An argument of -x may appear after the file arguments
to execute the linked program.
Any subsequent arguments are passed to the program.
Ucode files produced by translation are normally deleted after linking.
If the -c option is given, processing stops after translation
and the ucode files are left behind.
A directory of such files functions as a linkable library.
OPTIONS
The following options are recognized by icont:
- -c
-
Stop after producing ucode files.
- -f s
-
Enable full string invocation by preserving unreferenced procedures
during linking.
- -o file
-
Write the executable program to the specified file.
- -s
-
Suppress informative messages during translation and linking.
- -t
-
Activate runtime tracing by
arranging for &trace to have an initial value of -1
upon execution.
- -u
-
Diagnose undeclared identifiers.
- -v i
-
Set verbosity level of informative messages to i.
- -E
-
Direct the results of preprocessing to standard output and inhibit
further processing.
- -V
-
Announce version and configuration information on standard error.
TRANSLATION ENVIRONMENT
Two environment variables control file search paths during
translation and linking.
These variables contain blank- or colon-separated lists of directories
to be searched after the current directory
and before the standard library.
- IPATH
-
Directories to search for for ucode files
specified in link directives and on the command line.
- LPATH
-
Directories to search for source files
specified in preprocessor $include directives.
EXECUTION ENVIRONMENT
Several environment variables control the execution of an Icon program.
Values in parentheses are the default values.
- BLKSIZE (500000)
-
The initial size, in bytes, of the allocated block region.
- COEXPSIZE (2000)
-
The size, in words, of each co-expression stack.
- ICONCORE
-
If set, a core dump is produced for error termination.
- ICONX
-
The location of iconx, the icon interpreter,
overriding the value built into the executable by icont.
Not required if the configuration is unchanged since build time
or if iconx is in the same directory as the executable.
- MSTKSIZE (10000)
-
The size, in words, of the main interpreter stack for icont.
- NOERRBUF
-
By default, &errout is buffered. If this variable is set, &errout
is not buffered.
- QLSIZE (5000)
-
The size, in bytes, of the region used for pointers
to strings during garbage collection.
- STRSIZE (500000)
-
The initial size, in bytes, of the string space.
- TRACE
-
The initial value of &trace.
If this variable has a value, it overrides the translation-time
-t
option.

CAVEATS
Icon executables do not stand alone;
the iconx interpreter must be available.
