Declined Suggestions for V12

[Steve Fabian]

SET/ALIAS/FUNCTION/ASSOC/FTYPE

1/ For objects defined by the above commands one often needs the name of an
object, given its value, possibly as a subset or wildcard. A consistent set
of new options for these commands to make such a report would be very
useful.

2/ An option that would provide "tabular" output, i.e., whitespace replacing
the "=" sign normally separating the objects' names from their values to
vertically align the values would be very useful for visual inspection as
well as for automated processing.

3/ A new /O: option, to order the output by N(ame) or by V(alue), either
ascending or descending, including the choice between "intuitive" (numeric)
v. strictly alphanumeric order (as with DIR).

Steve,

Option #2 can be easily done using a BTM file. The following example
displays a list in columns.
I tried to genericize this batch file to accept both the command and the
column size.

setlocal
if .%1==. .or. .%2==. (echo usage %0 cmd column & quit)
setdos /x-145
do a in /P %1
echo %@left[%2,%@WORD["=",0,%a]%@repeat[ ,%2]]%@word["=",1-100,%a]
enddo
endlocal

Examples:
foo alias 11
foo set 25

Scott,
thanks for the tip. In the tc_plugins group I did just this kind of thing,
with the display command very similar to yours, using @FORMAT[] to
columnize. Your solution is more generic for the object value if it contains
embedded = signs.

Similar methods are possible to do all of the issues, e.g., in the DO loop
above one could ECHO only if the value contains the desired string. Once
could save all output in a file, and sort it in the desired order.

What I am looking for is to do it simply, by enhancing the reporting command
in the way PDIR enhances DIR's reporting format. Another detail: since the
tables are not very large, it is easy for an internal command to find the
minimum width required for the object names; a batch file would need to
either perform the retrieval twice, or save it in a temporary file. With the
/P option, and considering that all of these tables (except those of ASSOC
and FTYPE) are already in internal storage, retrieving twice should be the
faster.

Once more I'd suggest having [tab] work in tokens containing environment variables, like so (^ denotes the cursor position):

dir %systemroot%\a^[tab]*

which - on continuous key presses - should return the nth name in %systemroot% starting with 'a' (w/o the need to expand %systemroot% to e.g. "c:\windows\system32").

Right now one has to use the following command sequence to enumerate the 'a' names:

dir %systemroot%\a^[ctrl-x][tab]*

This sequence also forcibly expands %systemroot% to "c:\windows\system32", which is usually not what is wanted.
