Total Commander

There are loads of percent-prefixed parameters for button bar.
Should yet another one to be considered - for clipboard contents?
Most useful it might be for launching programs that are getting links from command line, but other scenarios are possible too.

I use the NirSoft tool Nircmd.exe for this purpose.

The following button displays a folder in TC which is read from the Clipboard. Usercmd.ini entry

The parameter is not quite suitable for this, because multiline text can be copied. It would be better if it were an environment variable, although it also has a length limit.
Personally, I prefer to handle the clipboard with scripts, because extra characters, including whitespace, often get there. In this case, you don't need to adjust specifically to a command or button, like the one above.

Already was. Use help button in TC.

I've done this before. There is no word "clipboard" on the "Environment variables" page.
If there was such a variable, then there would be no point in requesting a parameter.
There is only the [X] placeholder for MRT.

Adding an environment variable or pseudo-variable is not easier than a new parameter.
A true environment variable might get stale.
It would be a waste to add intermediate storage between clipboard and required parameter for a button.

Wrong. Try to execute from deep folder a few times: cd ..\%cd%
The path changes. What does this mean? That the variable is not outdated.
The same applies to variables such as COMMANDER_OPEN after changing conditions.

Examples of true environment variables: path, tmp.
%cd% is not, it is an internal TC's variable (launch cmd.exe, try your command).

Might mean, you are posting nonsense and messing up a very simple suggestion.
An intermediate variable for accessing clipboard contents is not cheaper than an additional %-parameter. Also it would be in the same help page, not elsewhere.

%cd% is not an internal TC variable, but an internal cmd.exe variable.

Edit:
In response to post below:

Code: Select all

c:\bin\wc>cd ..\%cd%
The filename, directory name, or volume label syntax is incorrect.

Of course the command "cd ..\c:\bin\wc" results in an error.

From cmd.exe window: Shall we stay on topic?

Edit. In response to the edit above.

Now try cd ..\%cd% in TC's command line input field.
Any difference in behaviour? If so, what is %cd% variable in this case?

All variables are true, regardless of whether they are internal or system.

It wasn't a question for you. Are you unable to distinguish a rhetorical question from a direct one from the context?
Rough and unfounded assessments do not interest me.

The help page is the last thing to think about. Implementation is much more important. I do not know how you measure the cheapness, but I pointed out the most important factor - multiline, which is excluded for a single-line parameter.

For the next beta, I have added two new pseudo environment variables %$CLIPBOARD% and %$CLIPNAME% with the following options:
%$CLIPBOARD% Inserts up to 1023 unmodified characters from the clipboard
%$CLIPBOARD0% Like %$CLIPBOARD%, but line breaks are replaced by spaces
%$CLIPBOARD1%, %$CLIPBOARD2% Inserts line 1, line 2 etc. from the clipboard, otherwise unchanged
%$CLIPNAME% Inserts up to 1023 characters from the clipboard, replaces the characters *?:|"<> that are forbidden in file names with underscores_
%$CLIPNAME0% Like %$CLIPNAME%, but line breaks are replaced by spaces
%$CLIPNAME1%, %$CLIPNAME2% Inserts line 1, line 2 etc. from the clipboard, replaces the characters *?:|"<> that are forbidden in file names with underscores_

What do you think?

Sounds great! A long awaited feature...
Thank you!

This should cover many more cases than were expected initially.

Very nice, so I can remove Nirsoft form many buttons.
