Description

Extracts an Inno Setup file and moves the files to an install directory. This is especially useful to work around the GOG installer. Uses the innoextract tool from http://constexpr.org/innoextract/

Usage

  1. Ask for a setup file using the builtin functions
  2. Create the Wine-prefix
  3. Create a temporary directory
  4. Set the install location to a folder inside the Wine-prefix.
  5. Call this script
  6. Apply your own registry patch, if necessary
  7. Clean up temp directory

Parameters

POL_innoextract <setup_file> <temp_dir> <install_path> [additional_args]
  • setup_file: Path of the setup file
  • temp_dir: Path to the temporary directory, usually created using POL_System_TmpCreate
  • install_path: Install location of the game as a native path (don't use "C:\something"). Example: "${WINEPREFIX}/drive_c/GOG Games/RollerCoaster Tycoon Deluxe/"
  • additional_args: Additional arguments for the innoextract process. May be usefull for installers with .bin files.

* Added script name to error messages
That one is actually interesting, because at first I thought that since POL_Debug_Fatal displays the name of the function calling it, it was redundant.
But POL_Calls are not just function calls, and what POL_Debug_Fatal displays is that the error comes from within "source" function; That makes sense, and yet is not what one would expect, I wonder if that could be improved...

innoextract --version >/dev/null 2>&1
if [ $? -ne 0 ]; then ...
You can also just use
if innoextract --version >/dev/null 2>&1; then ...
We're so used to use "if" with "test" that we sometimes forget it's just a special case of the way "if" works...
Saturday 26 December 2015 at 15:53 -
or rather in this case if ! innoextract --version >/dev/null 2>&1; then ...

I know, but it's very hard to read, that's why I did it this way.

My review:

INSTALLER_FILE="$1"
TEMP_DIR="$2"
INSTALL_PATH="$3"
ADDITIONAL_ARGS="$4"
Function scripts are sourced, it's recommended to declare those as local variables (using "local") to avoid collisions with calling script variables.

display_error ()
{
POL_SetupWindow_message "$1"
POL_SetupWindow_Close
exit $EXIT_ERROR
}
What about using POL_Debug_Fatal instead?

if [! innoextract --version >/dev/null 2>&1 ]; then
Did you test this line? [! gives a syntax error; Actually I think you don't need the square brackets in this case.

POL_Debug_Message "Found innoextract"
Shouldn't that be a fatal error too? The remaining of the function script cannot work correctly without innoextract.

POL_SetupWindow_file "$(eval_gettext 'Failed to extract files. Check if innoextract is up to date and the input file is valid. Read logfile for more information:')" "$TITLE" "$INNO_LOGFILE"
POL_SetupWindow_Close
exit $EXIT_ERROR
You probably missed this last place to use display_error or POL_Debug_Fatal

1. Thanks, I didn't know about local variables.

Oops, forgot I can't press enter in the comment window. New try:

1. Thanks, I didn't know about local variables.
2. I thought POL_Debug_Fatal works like POL_Debug_Message and silently logs to the terminal without displaying the error.
3. Yes, that's a very ugly line, I should have expected it to break.
4. There's an else before that line, it only executes if innoextract was found.
5. I'm using POL_SetupWindow_file to show the logfile, display_error uses POL_SetupWindow_message.

Thanks for your detailed feedback :)
