Done. (works for older john versions (force hash type NAME:
DES/BSDI/MD5/BF/AFS/LM/crypt...) and newer jumbo versions.
Together with the dynamic subformats (if available) we get more than 120
formats.
To avoid the "Display all n possibilities? (y or n)" promt, I decided to
provide this list in the first expansion step for
./john --format=

./john --format=dy ... ./john --format=dynami get expanded to ./john
--format=dynamic (without a trailing space.
./john --format=dynamic gets expanded to ./john --format=dynamic_
(again, without a trailing space).
Tab expansion for ./john --format=dynamic_ (press [tab] key twice) lists
these options:
dynamic_0 dynamic_1005 dynamic_13 dynamic_2 dynamic_26
dynamic_32 dynamic_8
dynamic_1 dynamic_1006 dynamic_14 dynamic_20 dynamic_27
dynamic_33 dynamic_9
dynamic_10 dynamic_1007 dynamic_15 dynamic_21 dynamic_28
dynamic_34
dynamic_1001 dynamic_1008 dynamic_16 dynamic_22 dynamic_29
dynamic_4
dynamic_1002 dynamic_1009 dynamic_17 dynamic_23 dynamic_3
dynamic_5
dynamic_1003 dynamic_11 dynamic_18 dynamic_24 dynamic_30
dynamic_6
dynamic_1004 dynamic_12 dynamic_19 dynamic_25 dynamic_31
dynamic_7
Better ideas?
for the non-jumbo version, it just lists these values:
john --format=
AFS BF BSDI crypt DES LM MD5

-sub gets expanded to --subformat=LIST.
(I use --subformat=LIST to get the list of dynamic_* formats for the
--format= expansion, as mentioned above.
./john --encoding=
ansi cp1252 cp437 cp850 cp866
iso-8859-15 koi8-r
cp1251 cp1253 cp737 cp858 iso-8859-1
iso-8859-7 utf-8
(Provided that the john version supports the --encoding=NAME option)

I'll expand -in or -inc to --incremental.
But currently expansion of -inc=Dig or --inc:Dig to -inc=Digits or
--incremental=Digits is not supported.
--incremental gets expanded to --incremental=
--incremental= uses the following hard coded list for expansion:
All Alnum Alpha Digits LanMan
(I'll not expand -incremental=)
As long as the john version supports an optional value for --rules and
--single (as indicated by the usage output), expansion for
./john --rules lists these (hard coded) values
--rules --rules=NT --rules=single --rules=wordlist
Expansion for --single lists these hard coded values:
--single --single=NT --single=single --single=wordlist
Expansion for --external= lists
AppendLuhn DateTime Filter_Alnum Filter_LanMan
LanMan Repeats
AtLeast1-Generic Double Filter_Alpha Keyboard
Parallel Strip
AtLeast1-Simple DumbForce Filter_Digits KnownForce
Policy Subsets
Expansion for ./john --save-memory= lists
1 2 3
For --wordlist=*|--config=*|--pot=*|--make-charset=*, I still list all
matching files and directories (in the current directory, unless the
value on the command line already includes path information).
I'm still thinking about removing the expansion for --make-charset=.
For --pot= and --config=, the list should probably filtered (just
directory names and *.pot or *.conf/*.ini files).
Still not working: correct handling of file names starting with ~.
Also currently not supported, but probably nice to have:
Expansion for ./john --restore and ./john --status
Less important:
--session=|--users=|--groups=|--shells=|--salts=
could be supported once I check the password hash files on the command
line. (It is questionable whether it is a good idea to process large
files in a shell script.)
Source code is still ugly.
But at least I managed to restrict usage of external commands to grep
and sed.
