Ubuntu Manpage: icont - translate Icon program

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.

       -p  Enable execution-time profiling; implied if ICONPROFILE is set and not empty.

       -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.

       -N  Don't embed iconx path in executable file.

       -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.

ICONPROFILE
If set, specifies a file to which profiling data is written upon termination of a
program linked with the -p option. The output reports timer ticks and visit counts
for each line executed.

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  are  not  self-sufficient,  but  require  the  iconx interpreter.  When
       distributing an Icon program in executable form, include a  copy  of  iconx  in  the  same
       directory.
