NAME
innoextract - tool to extract installers created by Inno Setup
SYNOPSIS
innoextract [--extract] [--lowercase] [options] [--] installers ...

DESCRIPTION
innoextract is a tool that can extract installer executables created by Inno Setup.
innoextract will extract files from installers specified on the command line.
To extract a multi-part installer with external data files, only the executable (.exe) file needs to be
given as an argument to innoextract.

OPTIONS
-- Treat all arguments after this one as files, even if they begin with a dash.
--collisions ACTION
Inno Setup installers can contain duplicate files with the same name. This option tells
innoextract what to do when such a collisions is encountered. Valid actions are:
"overwrite"
Extract only one of the colliding files. The choice is done similar to how Inno Setup
overwrites files during installation. This is the default.
"rename"
Rename files that would be overwritten using the "overwrite" action by appending a suffix
comprised of the file's language, the component it belongs to and/or a number to make the
filename unique. The language suffix (if applicable) is also appended to the default file
that would have been extracted with the "overwrite" action.
"rename-all"
Rename all colliding files by appending a suffix comprised of the file's language, the
component it belongs to and/or a number to make the filename unique. The complete suffix is
appended to both files that would have been overwritten using the "overwrite" action and to
those that would have overwritten other files.
"error"
Exit when a collision is detected.
Rename rules:
1. If the component is not the same for all files in the collision set (all files with the same
filename), "#" (without quotes) followed by the component id is appended to all files that are
specific to a single component.
2. If the language is not the same for all files in the collision set, "@" (without quotes)
followed by the language id is appended to all files that are specific to a single component
unless that language matches the default language specified by the --default-language. While the
suffix is omitted for the default language, no numbered suffix is added in it's place unless
needed to make the filename unique.
3. If no suffix was added by the previous steps, or if the filename is not yet unique, "$"
(without quotes) followed by the lowest integer (starting at 0) to make the filename unique is
appended.
With the "rename" action, steps 1 and 3 are only applied to files that would have been overwritten
by the "overwrite" action while "rename-all" applies them to all files in the collision set.
--default-language LANG
Set a language as the default.
With --collisions=overwrite (the default) this will change the choice of which file to keep to
always prefer the given language. In effect, --default-language behaves almost like --language,
except that files are extracted for all languages if they have different names.
When using the --collisions=rename option, --default-language chooses a language for which the
files should keep the original name if possible.
-c, --color[=ENABLE]
By default innoextract will try to detect if the terminal supports shell escape codes and enable
or disable color output accordingly. Specifically, colors will be enabled if both stdout and
stderr point to a TTY and the TERM environment variable is not set to "dumb". Pass 1 or true to
--color to force color output. Pass 0 or false to never output color codes.
--dump Don't convert Windows paths to UNIX paths and don't substitute constants in paths.
When combining --dump with --extract innoextract will not ensure that the paths don't point
outside the destination directory. Use this option with caution when handling untrusted files.
-m, --exclude-temp
Don't extract files that would have been deleted at the end of the install process. Such files are
marked with [temp] in the file listing.
This option takes precedence over --include and --language: temporary files are never extracted
when using the --exclude-temp, even if they match the selected language or include expressions.
-e, --extract
Extract all files to the current directory. This action is enabled by default, unless either
--list or --extract is specified. You may only specify one of --extract and --test.
-g, --gog
Try to process additional .bin files that have the same basename as the setup but are not actually
part of the Inno Setup installer. This is the case for newer multi-part GOG.com installers where
these .bin files are RAR archives, potential encrypted with the MD5 checksum of the game ID (see
the --gog-game-id option).
Extracting these RAR archives requires rar, unrar or lsar/unar command-line utilities to be in the
PATH.
The --list, --test, --extract and --output-dir options are passed along to unrar/unar, but other
options may be ignored for the RAR files. For multi-part RAR archives, the --test requires a
writable output directory for temporary files.
Note that is option is geared towards GOG.com installers. Other installers may come be bundled
with different extraneous .bin which this option might not be able to handle.
--gog-game-id
Determine the ID used by GOG.com for the game contained in this installer. This will only work
with Galaxy-ready GOG.com installers.
This option can be combined with --silent to print only the game ID without additional syntax that
would make consumption by other scripts harder.
The --gog-game-id action can be combined with --list, --test, --extract and/or --list-languages.
If --silent and --gog-game-id are combined with --list and/or --list-languages, the game ID (or an
empty line) will be printed on it's own line before the file list but after the language list.
For newer multi-part GOG.com installers the .bin files are not part of the Inno Setup installer
but instead are RAR archives. Some of these RAR files are encrypted, with the password being the
MD5 checksum of the game ID:
innoextract --gog-game-id --silent setup_....exe | md5sum | cut -d ' ' -f 1
-h, --help
Show a list of the supported options.
-I, --include EXPR
If this option is specified, innoextract will only process files whose path matches EXPR. The
expression can be either a single path component (a file or directory name) or a series of
successive path components joined by the OS path separator (\ on Windows, / elsewhere).
The expression is always matched against one or more full path components. Filtering by parts of
filenames is currently not supported. Matching is done case-insensitively.
EXPR may contain one leading path separator, in which case the rest of the expression is matched
against the start of the path. Otherwise, the expression is matched against any part of the path.
The --include option may be repeated in order allow files matching against one of multiple
patterns. If --include is not used, all files are processed.
--language LANG
Extract only language-independent files and files for the given language. By default all files are
extracted.
To also skip language-independent files, combine this option with --language-only.
--language-only
Only extract files that are language-specific.
This option can be combined with --language to only extract the files of a specific language.
--license
Show license information.
-l, --list
List files contained in the installer but don't extract anything.
This option can be combined with --silent to print only the names of the contained files (one per
line) without additional syntax that would make consumption by other scripts harder.
The --list action can be combined with --test, --extract, --list-languages and/or --gog-game-id to
display the names of the files as they are extracted even with --silent.
--list-languages
List languages supported by the installer.
This option can be combined with --silent to print only the identifiers of the languages (one per
line) followed by a space and then the language name, without additional syntax that would make
consumption by other scripts harder.
The --list-languages action can be combined with --list, --test, --extract and/or --gog-game-id to
display the available languages before doing anything else. If --silent and --list-languages are
combined with --list and/or --gog-game-id, the languages list will be terminated with an empty
line and will precede both the game ID and files list.
-L, --lowercase
Convert filenames stored in the installer to lower-case before extracting.
-d, --output-dir DIR
Extract all files into the given directory. By default, innoextract will extract all files to the
current directory.
If the specified directory does not exist, it will be created. However, the parent directory must
exist or extracting will fail.
-p, --progress[=ENABLE]
By default innoextract will try to detect if the terminal supports shell escape codes and enable
or disable progress bar output accordingly. Pass 1 or true to --progress to force progress bar
output. Pass 0 or false to never show a progress bar.
-q, --quiet
Less verbose output.
-s, --silent
Don't output anything except errors and warnings unless explicitly requested.
This option can be combined with --list to print only the names of the contained files (one per
line) without additional syntax that would make consumption by other scripts harder.
-t, --test
Test archive integrity but don't write any output files. You may only specify one of --extract and
--test.
-T, --timestamps TZ
Inno Setup installers can contain timestamps in both UTC and 'local' timezones.
The --timestamps option specifies what timezone should be used to adjust these 'local' file times.
Valid values are those accepted by tzset in the TZ environment variable, except with the direction
of the time offset reversed: both -T CET and -T GMT+1 will (when DST is in effect) give the same
result.
Besides timezones, two special values are accepted:
"none" Don't preserve file times for extracted files, both for UTC and 'local' timestamps. The
file times wil be left the way the OS set them when creating the output files.
"local" Use the system timezone for 'local' timestamps. This is the normal Inno Setup behavior,
and can be used together with the TZ environment variable.
The default value for this option is UTC, causing innoextract to not adjust 'local' file times.
File times marked as UTC in the Inno Setup file will never be adjusted no matter what --timestamps
is set to.
-v, --version
Print the innoextract version number and supported Inno Setup versions.
If combined with the --silent option, only the version number is printed. Otherwise, the output
will contain the name (innoextract) followed by the version number on the first line, and, unless
the --quiet options is specified, the range of suuported Inno Setup installer versions on the
second line.
--no-warn-unused
By default, innoextract will print a warning if it encounters .bin files that look like they could
be part of the setup but are not used. This option disables that warning.
PATH CONSTANTS
Paths in Inno Setup installers can contain constants (variable or code references) that are expanded at
install time. innoextract expands all such constants to their name and replaces unsafe characters with
$. For exmaple {app} is expanded to app while {code:Example} is expanded to code$Example.
There is currently no way to configure this expansion except for disabling it with the --dump option.
EXIT VALUES
0 Success
1 Syntax or usage error
2+ Broken or unsupported setup file, or input/output error
LIMITATIONS
There is no support for extracting individual components and limited support for filtering by name.
Included scripts and checks are not executed.
The mapping from Inno Setup constants like the application directory to subdirectories is hard-coded.
Names for data slice/disk files in multi-file installers must follow the standard naming scheme.
Encrypted installers are not supported.
