NAME
inform - compile Inform interactive fiction story files to Z-machine or Glulx bytecode
SYNOPSIS
inform [options...] infile [outfile]
DESCRIPTION
inform compiles an Inform version 6 story file (usually with the extension .inf) into Z-machine or Glulx
bytecode which can then be executed by a variety of Z-machine or Glulx emulators. If the output filename
is not explicitly given on the command line, it will be constructed from the input filename.
inform's mode of operation can be controlled with switches (one or two-character expressions preceded by
a dash), path modifiers (starting with a plus sign) and memory strategy modifiers (starting with a dollar
sign).
SWITCHES
-a trace assembly-language (without hex dumps; see -t)
-c more concise error messages
-d contract double spaces after full stops in text
-d2 contract double spaces after exclamation and question marks, too
-e economy mode (slower): make use of declared abbreviations
-f frequencies mode: show how useful abbreviations are
-g traces calls to functions (except in the library)
-g2 traces calls to all functions
--help, -h, -h1, -h2
print usage information
-i ignore default switches set within the file
-j list objects as constructed
-k output Infix debugging information to "gameinfo.dbg" (and switch -D on)
-l list every statement run through Inform
-m say how much memory has been allocated
-n print numbers of properties, attributes and actions
-o print offset addresses
-p give percentage breakdown of story file
-q keep quiet about obsolete usages
-r record all the text to "gametext.txt"
-s give statistics
-t trace assembly-language (with full hex dumps; see -a)
-u work out most useful abbreviations (very very slowly)
-vn compile to a specific Z-code version; the default is 5. Available versions are:
3 version-3 ("Standard") story file
4 version-4 ("Plus") story file
5 version-5 ("Advanced") story file
6 version-6 (graphical) story file
8 version-8 (expanded "Advanced") story file
-w disable warning messages
-x print # for every 100 lines compiled
-y trace linking system
-z print memory map of the Z-machine
-B use big memory model (for large version-6/version-7 files)
-Cn select text character set (defaults to 1):
0 plain ASCII only
1 ISO 8859-1 (Latin1)
2 ISO 8859-2 (Latin2)
3 ISO 8859-3 (Latin3)
4 ISO 8859-4 (Latin4)
5 ISO 8859-5 (Cyrillic)
6 ISO 8859-6 (Arabic)
7 ISO 8859-7 (Greek)
8 ISO 8859-8 (Hebrew)
9 ISO 8859-9 (Latin5)
u Unicode (UTF-8)
-D insert "Constant DEBUG;" automatically
-En select error message style (default is Archimedes):
0 Archimedes-style error messages
1 Microsoft-style error messages
2 Macintosh MPW-style error messages
-F1 use temporary files to reduce memory consumption
-G compile a Glulx game file
-H use Huffman encoding to compress Glulx strings
-M compile as a Module for future linking
-S compile strict error-checking at run-time (on by default)
-U insert "Constant USE_MODULES;" automatically
-V display version and exit
-Wn header extension table is at least n words (n = 3 to 99)
-X compile with INFIX debugging facilities present
PATH MODIFIERS
--path PATH=dir
change PATH to this directory
--addpath PATH=dir
add this directory to the PATH
PATH MODIFIERS (old style)
+dir set Include_Path to this directory
++dir add this directory to Include_Path
+PATH=dir
change PATH to this directory
++PATH=dir
add this directory to the PATH
MEMORY SETTINGS
--list
List current memory allocation settings.
--helpopt SETTING
explain briefly what SETTING is for
--opt SETTING=number
change SETTING to given number
--define SYMBOL=number
define define SYMBOL as a constant in this story
--config filename.icl
read in a list of commands (in the format above) from this setup file. See INFORM COMMAND
LANGUAGE below
MEMORY STRATEGY MODIFIERS (old style)
Note: it may be necessary to quote these parameters to prevent your shell from expanding them.
$list list current memory allocation settings
$?SETTING
explain memory setting SETTING (see $list for available parameters)
$SETTING=number
manually set SETTING to given number
$#SYMBOL=number
define SYMBOL as a constant in the story
(filename.icl)
read in a list of commands (in the format above) from this setup file. See INFORM COMMAND
LANGUAGE below
INFORM COMMAND LANGUAGE
The Switches directive, which enables certain compiler switches to be set from within the source file
rather than on the compiler command line, has been superseded by a more powerful mechanism. The special
comment characters "!%", occurring on the very first line or lines of the source file, enable you to
specify Inform Command Language (ICL) commands to control the compilation. For example:
!% -E1G ! Glulx, 'Microsoft' errors
!% -~S ! disable Strict mode
!% +include_path=./test,./,../lib/contrib ! look in 'test' library
!% $MAX_STATIC_MEMORY=20000
Constant STORY "RUINS";
...
ICL is described in Section 39 of the Inform Designer's Manual. In brief: each line specifies a single
command, starting with "-" to define one or more switches, "+" to define a path variable, or "$" to
define a memory setting. Comments are introduced by "$". The ICL command "compile" is not permitted at
the head of a source file.
CAVEATS
inform is not capable of creating story files conforming to versions 1 or 2 of the Z-Machine.
Modules cannot be used with Glulx and are deprecated for Z-Machine.

AUTHOR
The various iterations of the Inform language were created by Graham Nelson in 1993.
This manpage was written by Jan Nordholz <hesso@pool.math.tu-berlin.de> for the Debian Project and
altered by David Griffith <dave@661.org>.
DISTRIBUTION
The compiler and standard library for Inform6 are licensed under
1) The traditional Inform license as described by the DM4, or
2) The Artistic License 2.0 .
Here is the relevant bit from the Inform Designer's Manual, 4th edition:
Copyright on Inform, the program and its source code, its example games and documentation (including this
book) is retained by Graham Nelson, who asserts the moral right to be identified as the author under the
Copyrights, Designs and Patents Act 1988. Having said this, I am happy for it to be freely distributed
to anybody who wants a copy, provided that: (a) distributed copies are not substantially different from
those archived by the author, (b) this and other copyright messages are always retained in full, and (c)
no profit is involved. (Exceptions to these rules must be negotiated directly with the author.)
However, a story file produced with the Inform compiler (and libraries) then belongs to its author, and
may be sold for profit if desired, provided that its game banner contains the information that it was
compiled by Inform, and the Inform version number.
