%$DATE% only resolved in command field

[Horst.Epp]

The new date variable %$DATE% is only resolved in the command field of a button.
This makes it useless for most purposes.
It should be resolved as parameters.

On TC11b3 x32 doesn't work.
Command: %ComSpec% /k echo %$DATE%
Parameters: ?%|$DATE:Y-M-D h.m.s|

Returns: %$DATE% %$DATE:Y-M-D h.m.s%

Strange - fully works here on both x32 and x64 versions on Windows 10

[Fla$her]

And on XP and 7 how?

I can confirm that it works at my place as well, with both TC versions running on Win10 x64.

Support for the suggestion.

Parameters: ?%|$DATE:Y-M-D h.m.s|

And on XP and 7 how?

Here, the above works fine on Windows 7 and 10, but NOT on Windows XP

On Windows XP it does not work for neither the Command field nor the Parameters field.

Works on Windows 7, on XP i didn't try.

Confirm. I tested it on XP first. Probably, the same problems exist on earlier versions.

Support for the suggestion.

%|var|, which appeared in the first beta, applies to all environment variables. There's nothing to add.

The function to load the %$pseudovar% variables loads and uses the function SHGetKnownFolderPath, which doesn't exist on Windows XP.
I will check for $DATE before trying to load SHGetKnownFolderPath.

I will check for $DATE before trying to load SHGetKnownFolderPath.

And what will it give?

[Horst.Epp]

A very simple test under Windows 11 shows that %$DATE% doesn't work in the parameters of a button.
The button starts a cmd script which echos the parameters.

Using the %$DATE% in the command field after the cmd path it works and delivers a date.
If %$DATE% is in the parameters field it simply gets DATE

It will work also on older Windows versions where SHGetKnownFolderPath doesn't exist, like Windows XP.

A very simple test under Windows 11 shows that %$DATE% doesn't work in the parameters of a button.

The parameters field does not support environment variables normally because it supports paramters like %P%N. This would collide with a variable name %P%. Therefore the syntax is different there:
%|Variable name|

Good! Thanks for the explanation.

Ok, now I can use it
Here my button to pack all selected files/dirs from the source to the target side.
The archive is named like the source dir followed by the current date time.
Example Dirname_20230518_1845

Code: Select all

TOTALCMD#BAR#DATA
"C:\Program Files\7-Zip\7z.exe"
a %T%B_%|$DATE:YMD_hm| @%UL -aoa -mmt -mx9 -ssw -stl -ssp -y -mx9
C:\Program Files\7-Zip\7zFM.exe
Pack selected

FIxed for XP.
