User Command for hashing console programs

[Axis]

Hi to all.

Since TC10 won't have the new hashing algorithms (XXH3, Blake3) I need, I'm trying to create my own user command (to put in the start menu).

Unfortunately, the hash programs I use do not accept the %L parameter as input, so they hash the temp file (instead of hashing Its content).

I would like to get a behavior like TC's native hashing, so:

- Select files, folders (with other files inside them), etc., in TC.
- Run the user command that in turn invokes the hashing program to generate the hashing of everything has been selected by the user (exactly as tc does with Its native hashing algorithms like md5, crc32, sha-x, etc.).


Any idea (yep, to me is very difficult. I was hoping for tc10)?


Many thanks.

If your Hash program supports multiple files/dirs in the command line then you could try and use the %S parameter.

I'm trying with dirhash, it doesn't work (with %S, %L, etc.).

[Dalai]

If your hash program doesn't support list files (or multiple parameters like %S provides), you're going to need some kind of loop that calls the hash program for every file. This will impact performance a lot because the forking of processes is expensive in terms of resources (CPU load).

You can use the tool List To MultiInstance (Lst2Multi)
https://www.ghisler.com/dtools.htm
It will of course take some time for a large number of files.

The program supports stdin as input ("When no filename provided or when '-' is provided, uses stdin as input."): could it help that?

Thanks, I'll try
(but it's a pain in the ass: tc really starts to irritate me)

As i can see, the program (if it is this one https://github.com/idrassi/DirHash/releases/tag/DirHash_1.18.0) only supports one parametar as the name of the file or dir. It doesn't even support wildcards.

It is a limitation of the program, not TC.

For handling such situation there is Lst2Multi as @Horst.Epp suggested. Use it to send all the filenames to it and the Lst2Multi will run the external program as many times as necessary, each time with another single filename.

F4Menu has the same functionality, although it is not its main purpose.

I was referring ("tc really starts to irritate me") to being forced to non-native solutions for something that could be quickly (maybe) inserted into TC (at least put one between Blake3 or Xxh3).

It doesn't support Internal TC variables (I tried with %commander_path% and %commander_drive%), so goodbye tc's portability

Sorry thats nonsense.
TC starts the lst2mlt.exe with a button you define
and of course TC knows about %COMMANDER_PATH% and its other variables.

TC 9.22 x64, Start menu:

Command: "%commander_path%\utils\lst2mlt\lst2mlt.exe"

Parameters: /X:"%commander_path%\utils\DirHash\DirHash.exe" /L:"%L"

You have to double the percent signs (of environment variables) in the Parameters field because letters prefixed by a single percent sign are considered placeholders by TC, like %C, %P, %N and so on. When supplying the parameters within the Command field, the percent signs don't need to be doubled.

I tried
-------------------
Command: "%commander_path%\utils\lst2mlt\lst2mlt.exe"

Parameters: /X:"%%commander_path%%\utils\DirHash\DirHash.exe" /L:"%L"
-------------------
Not working ("Windows cannot find '%commander_path%\utils\DirHash\DirHash.exe'. Make sure you typed the name correctly, and then try again.").

Thanks

Try
Command: utils\lst2multi\lst2mlt.exe
parameters: /X:"utils\DirHash\DirHash.exe" /L:"%L"
you probably don't need %commander_path% is it is relative to the TC anyway. (works here)

Edit: replace "lst2multi" with "lst2mlt"
