Feature request: The rest of arguments syntax: `%An*`

[andry81]

Currently there is no way to use like this:

Code: Select all

em_blabla pos1 pos2 flag1 flag2 ... flagN

Code: Select all

[em_blabla]
cmd=...
param=... %A3* -- %A1 %A2

If positional parameters always has a fixed set. When flag parameters basically a variable set.

So if you use it in commands, then you have to swap the order to use a variable parameter set at the command line end.

But there is no way to use `the rest of %A` syntax in Total Commander.

Considering my suggestion, I propose to expand the capabilities:

%An+, %Sn+, %Rn+ — parameters starting from n.
%An+m, %Sn+m, %Rn+m — parameters from n to m.
%An-, %Sn-, %Rn- — the last n parameters.

May be extend by using open/close characters like in the Unix shell?

String slice:

%A:~n, %A:~n,m, %A:~n,-m, %A:~-n — stringize %A and then slice a substring.
%A1:~n, %A1:~n,m, %A1:~n,-m, %A1:~-n — stringize %A1 and then slice a substring.

Array slice:

%{A[n:]}, %{A[n:m]}, %{A[n:-m]}, %{A[:n]}, %{A[:-n]} — slice an array.

This will prevent misuse, when the followed character does not actually start a range selection sequence.

%{A}:.., %{A1}:.. - %A expanded as is without slicing.
%A[n:], %A[n:m], %A[n:-m], %A[:n], %A[:-n], %A[... — %A expanded as %A without slicing.
%%A, %%{ - raw strings.

We already have %B-, %B-n, %B+ and %B+n, but only one component is extracted there. For the group, it makes sense to indicate the sign after n.
However, the syntax is not as important as the implementation itself. I think the author will figure out the best way.

These does slice for file paths. If you try to continue use it, then it will bring much more problems.
When mine variant does fix it too.

%B here expands as is:

Code: Select all

%{B}-, %{B}-n, %{B}+, %{B}+n

Why should I try? I already use it successfully as the author of the suggestion.

%B here expands as is:

I don't understand what you mean by that.

B=a/b/c

Code: Select all

%{B}-123

Expands to:

Code: Select all

a/b/c-123

Code: Select all

%B-123

Expands to:

Code: Select all

a23

It depends on the working directory.
If "C:\1\2\3\4\5\6\7\8\9\10\11\" is open, %B-123 will return 1023. 23 is excluded because 9 is the upper limit.

My example show how to escape the excessive expansion.

[Fla$her]

What, in your opinion, is an excessive expansion in this case?

Consumed characters because of accident of an expansion.

[Fla$her]

I don't quite understand your wording. Could you highlight these characters in the example?

Do you understand that the characters after a `%B` sequence can be a legit path or a string? A user might will want to escape these and could not do it.

For example, in a particular case you can do it:

Code: Select all

cmd=cmd.exe /k
params=echo %B^-00

But can not in a generic case.
