Improved arc.groups processing

arc1.arc updated:

• line "$precomp $compressed" in arc.group now denote $precomp if such group presents in current compression method and $compressed otherwise

This allows fine-grain definition of compression groups, for example:

$precomp
*.pdf
$precomp $compressed
*.zip
*.jpg
$compressed
*.arc

files in second group will be included in group $compressed in -m4 compression mode, but in $precomp in -max compression mode

Lot of small cleanup changes

arc1.arc updated:

• GUI: after operation was completed, Cancel becomes the default key in progress dialog so you can close it by pressing just Enter/Space
• fixed bug in dict (addressing memory beyond end of buffer) and a few UI problems
• included latest InnoSetup scripts & dll
• Added license info to About and console help
• facompress.dll: now loaded only from directory where FreeArc executable resides since loading something from PATH may lead to FreeArc versions incompatibility
• LZMA: decompressor now writes data in 8mb chunks (instead of dictsize) that means smoother progress indicator
• error messages: now reports "read error" or "write error" instead of "i/o error"
  

Now errors and warnings are shown in GUI and execution paused before exit if necessary

arc1.arc updated, with issue 62 implemented:

added option --pause-before-exit with the following settings:
on - always make a pause
off - never make a pause
on-warnings - make pause if there were any warnings due operation
on-error - if program exits due to error

default settings for the option:
off - for console mode
on - for "test" command in GUI mode
on-warnings - for other commands in GUI mode

in FileManager mode this option is ignored

also, errors and warnings are displayed inside GUI window (in non-FileManager mode), so you can see them both due operation and after it was finished

finally, Escape key now may be used to exit program (in non-FileManager mode), like Alt-F4. when you exit program after operation was finished, "Abort operation?" don't
asked

Bugfixing continues..

updated arc1. fixed:

• -ld default value sometimes didn't worked
• Reread archive after modification operation

Compression reliability improvements

updated arc1:

• wininet.dll: dynamic loading
• Polished compression method definitions
• -mx sometimes failed on large files
• Program hanged up after compressing 8k files selected in file manager

btw, updated compression methods definitions are in freearc.history file, so you may want to update this file or at least copy "compression=..." lines from it

InnoSetup support upadted

http://www.haskell.org/bz/FreeArc4InnoSetup.zip updated:

• full english translation
• overall progress indicator for all archives in the installation
• graceful exit when archive being extracted is corrupt

More Explorer commands and new InnoSetup support

arc1 updated:

• new, unicode-aware version of All2Arc utility
• added Add../Extract.../Modify.../Join.../Convert... commands to Explorer context menu
• added Convert command to FreeArc menu
• unarc.dll for extracting FreeArc archives in other programs
• example of Inno Setup installation script that extracts files from FreeArc archives using unarc.dll
