How to use Command_ in .NET Plugin SDK

[Joe Caverly]

Using the traditional SDK with PureBasic to develope a plugin, I could...

ImportC "takecmd.lib"
  Command_(*lpszString, nReserved) As "Command"
  Evaluate_(*lpszString) As "Evaluate"
  SetEVariable_(*lpszString) As "SetEVariable"
EndImport

...and then I could do things like...

Command_("echo USAGE: Test %_year-1960",0)
Command_("set abc=123", 0)
Command_("echo " + theResult, 0)
Command_("type tmp:",0)
Command_("type " + theFile + " > tmp:",0)

How can I do this using C# and the .NET Plugin SDK for TCC?

If the anwser is contained in DotNetPluginSDK.cs,
or DotNetPluginGuide.md,
then I have missed it.

Thinking out loud...

Would it be possible to call into the takecmd.dll using a P/Invoke from C#?

[DllImport("takecmd.dll", EntryPoint = "Command", CharSet = CharSet.Unicode)]
static extern int Command_(string command, int reserved);

...which I believe is...

C:\...\TCMD36>exports takecmd.dll | ffind /kmt"?Command_"

Invoke-TccCommand (or its alias tcc) is the PowerShell function that calls back into Take Command to execute a TCC command. It works through this chain:

1. PowerShell side: Invoke-TccCommand calls [TakeCommand.PowerShellHost]::InvokeCommand($Command)
2. Managed bridge: InvokeCommand calls InvokeHostCallback, which invokes the native callback pointer gpfnHostCommandCallback
3. Native side: That callback (registered via TCCPowerShell_SetHostCallbacks) is where TCC processes the command string (e.g., "copy ...", "dir ...")

Usage from PowerShell:

# Full function name
Invoke-TccCommand "dir /s /b *.txt"

# Or using the alias
tcc "copy file1.txt file2.txt"

-----------------------------------

If this isn't working, let me know.

Yes, but I do not want to do that from PowerShell.

I want to do it from a C# code (plugin),
as I indicated in my OP.

I want to, from the C# .NET plugin;

Command_("echo USAGE: Test %_year-1960",0)
Command_("set abc=123", 0)
Command_("echo " + theResult, 0)
Command_("type tmp:",0)
Command_("type " + theFile + " > tmp:",0)

Would you please modify the Greet example plugin code that is contained in DotNetPluginGuide.md to demonstrate how to do this?

There isn't currently any support for that in .NET plugins. I will add support for that to build 23.

I've added a topic to the help for build 23 under Plugins / Calling TCC Commands from .NET.
