Information about user-defined commands em_

[kodepr]

Hi,

I'm going through TC help file to learn some new things.

Help mentions: "Additionally, you can define your own commands with prefix em_ via "Choose command" and then use them here."

- Not much shows up when searching the help file for "em_". Where can I find more information about userd-defined commands?
- I have no programming skills whatsoever. Is this worth looking into or is this way out of my league?

It's very easy.
E.g. you can build user command for run NOTEPAD.EXE and open file from cursor, so set NOTEPAD.EXE as a command and %P%N (file path+name) as a parameter resulting such a entry in USERCMD.INI

[em_notepad]
cmd=NOTEPAD.EXE
param=%P%N

An example from my usercmd.ini

Code: Select all

[em_TeraCopy]
button=c:\tools\TeraCopy\TeraCopy.exe,0
cmd=c:\tools\TeraCopy\TeraCopy.exe
menu=Copy with TeraCopy
param=Copy *"%UL" "%T" /NoClose

em_TeraCopy is the name for adding it into a button or menu
Button defines the icon
Cmd defines the tool to start
Menu is the tooltip for the button
Param contains the parameters for the tool to start

I see, thanks.

2 questions:

1. Created your Notepad example with Change start menu. Then %P%N doesn't work for me after selecting a .txt file and then selecting the Notepad command in the start menu. Only works if I change parameters to %P%S. Or should I select files/run command in a different way if parameters are set to %P%N?
2. Probably my fault, but from the Notepad example I don't see the advantage of user-defined commands. I already have buttons in Total Commander that have the same functionality. Button command is path to an .exe and parameters is set to %P%S. Same functionality without the need for a user-defined command. What am I missing to understand benefits of userd-defined commands?

Will look into TeraCopy (never heard of it before) and your TeraCopy example asap.

You can add cm_ and em_commands in View mode settings
but not your simple button definitions.
Also you can chain such commands for more complex jobs.

%P%N is normal for single selected files and definitely works in buttons and commands.
Read the button help what %S is for

Hi,
em_commands are required, for example, to create/re-define shortcuts.
(Configuration -> Options... -> Misc. -> Redefine hotkeys (Keyboard remapping) ...).

Example (shortcut Shift+Y):
It is saved in the file: wincmd.ini in the [Shortcuts] section:
S+Y=em_CD_D-Daten_I-Daten

---

Furthermore, several commands can be used in one button, including em_commands - example:
3 em_commands for 1 button.

Button with command:
cm_50Percent,em_CD_D-Daten_I-Daten
------------------------------------------------
em_command:em_CD_D-Daten_I-Daten
Command: cm_FocusLeft,cm_SrcActivateTab1,em_D-Daten,cm_TrgActivateTab1,em_I-Daten,cm_FocusLeft,cm_RereadSource,cm_rereadsource 1

em_command:em_D-Daten
Command: cd D:\Daten

em_command:em_I-Daten
Command: command: cd I:\Daten

Important:
No spaces are allowed in the name of em_commands!

This has the effect that after clicking on the button with command: cm_50Percent,em_CD_D-Daten_I-Daten
- the view is set to 50:50, if necessary
- In the left window, the directory D:\Daten\*.* is set for the first tab and this tab is activated
- In the right-hand window, the directory I:\Daten\*.* is set for the first tab (window inactive).
- updates of the view are carried out
Instead of clicking on the button, the shortcut Shift+Y can also be used (if defined - please see above).

The description of the individual commands, e.g. cm_SrcActivateTab1 can be viewed either in the CommandBrowser
(enter cm_CommandBrowser in the command line of Total Commander and press ENTER, then enter the command in the "Filter" field)
or you can search/filter for the term cm_RereadSource in the file HISTORY.TXT.

One can probably list other advantages of em_commands...

It's just example, as simple as possible to learn how build user command. Benefit in any case is possibility to use user command in menus.
You can of course make more complex user command.

Here is another small(!) example with step-by-step instructions.

For inspiration you could try my Extended Menus (see signature) - there is more than 550 em_commands in use.
