Plugins: ArcLite, Hash/CRC calculator

[ElVasquito]

Any chance of having those plugins? The one I really miss is ArcLite, as it can get inside many file formats: disk images (floppy/CramFS/SquashFS/VDI/VMDK...), executables, and many more containers, and extract data out of them very easily.
Hash/CRC calculator: https://plugring.farmanager.com/plugin.php?pid=695&l=en
I don't know if this last one can be ported though, as it's made in Pascal.

Many thanks in advance.

If you're under Linux can enter into ELF executables by Ctrl+PgDown - there is 'inside' plugin that handles ELF and some other formats. If you're under MacOS - ops, not implemented yet.
Libarchive used in multiarch also supports various of formats for reading: https://github.com/libarchive/libarchive/wiki/LibarchiveFormats

[ElVasquito]

Thank you, yes, MultiArc with Libarchive is great, but disk images are not supported and it is very useful to get inside them in Far to view/extract data directly.

[elfmz]

Potentially it can be done by using libguestfs (https://en.wikipedia.org/wiki/Libguestfs), but to be honest doesnt looks as something that will be added tomorrow..

[ElVasquito]

Didn't know about that library. Sounds great, even supporting write to the images! However, I find ArcLite would be more useful as it supports many more formats to get "inside" from Far. Would ArcLite be more difficult to port? Please do consider to setup a "donations" page. Thank you for the work you've done!

[elfmz]

What you mean 'many more formats to get "inside" from Far.' ?
As i already wrote, there is far2l-specific plugin named 'inside' it also supports decoding some formats, and it a bit configurable, see: https://github.com/elfmz/far2l/blob/master/inside/configs/plug/config.ini
Regarding ArcLite - it uses 7z.dll, and there is such librry in repos. If to consider sources of 7z app itself, its code is very.. singular:) Its problem that 7z engine was not designed to be library. So for porting it would be best to be an author of 7z:) and still see no exclusive benefits. Also i always afraid of files longer than 1k lines, like this https://github.com/FarGroup/FarManager/blob/master/plugins/arclite/ui.cpp and this https://github.com/FarGroup/FarManager/blob/master/plugins/arclite/archive.cpp.
Multiarc code is much more laconic, even thought also much more legacy, but when porting code - simplicity rules.
And as you noted - libguestfs is more powerful than ArcLite for images support, libarchive is somewhat similar for archives support.. Well, it has weaker 7z support but stronger .tar. support that is perfectly fine for *nix file manager.

[ElVasquito]

Quote from its webpage:
"libguestfs can access almost any disk image imaginable."
Well, I did not see CramFS/SquashFS images mentioned anywhere in the page, and after reading the supported 7z formats:

Supported formats:
Packing / unpacking: 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIM
Unpacking only: AR, ARJ, CAB, CHM, CPIO, CramFS, DMG, EXT, FAT, GPT, HFS, IHEX, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, QCOW2, RAR, RPM, SquashFS, UDF, UEFI, VDI, VHD, VMDK, WIM, XAR and Z.

I thought about that line :)
Now that I actually downloaded the library's tarball and checked it, I found this:
Add cramfs and squashfs kernel modules (RHBZ#503135).
So yes they should be supported :)
Understand about those big files, a pain in the butt, let's forget it.
Libguestfs would definitely be much more useful for Far, and MultiArc+Inside are perfectly fine as is.

[unxed]

Personally, it would be very, very useful for me to have libgestfs supported in multiarc to open VDI images of Virtualbox, in which I often build far2l for different distributions.

[unxed]

@elfmz well, where custom.ini for multiarc should be placed? Want to try to add VDI support through command line 7z via custom format support in multiarc

[elfmz]

~/.config/far2l/multiarc/custom.ini
..hope it still works. Never tested since ported ;)

[unxed]

Thanks, it works perfectly! As i found out, another option is to place custom.ini in same folder with multiarc.far-plug-mb (for example, /usr/lib/far2l/Plugins/multiarc/plug/) for any user to be able to use it.

Here is config for VirtualBox .vdi image file format. Don't forget to install p7zip-full package (sudo apt install p7zip-full on Ubuntu/Debian).

Could this VDI support be please added as default? Thanks!

[ElVasquito]

That's very nice @unxed!
Attached sample images, the "custom*.img" and "romfs*.img" are CramFS images, the bigger "user-x*.img" is a SquashFS image.
