Notepad object member function to rename unsaved tab

[sasumner]

This is a FEATURE REQUEST.

Notepad++ version 7.6.4 (I think) brought the capability to rename an unsaved tab.

For example, a tab with the title "new 2" can be right-clicked upon, "Rename" chosen from the resulting popup menu, and the following box presents:

Entering a value changes the current tab's title to the specified name.

WHAT I'D LIKE: A way to do this programmatically, say with a notepad.rename('My new name') function call.

Perhaps there are dependency problems with supporting this; for instance, does the Notepad++ plugin interface currently permit plugins to rename an unsaved tab?

There also might be logistical problems in uniquely identifying tabs with the same name (yes, Notepad++'s implementation currently allows this) for purposes of, say notepad.getFiles() calls. But, I suppose this is a Notepad++ "problem" (don't allow it), or a user "problem" (don't name two tabs with the same name).

Seems no interface is available for renaming in https://npp-user-manual.org/docs/plugin-communication/#notepad-messages.

Checkin was notepad-plus-plus/notepad-plus-plus@3546268.

So currently just the MENUCOMMAND.FILE_RENAME would be an option.

It looks like the "N++ extension needed" part isn't going to be fulfilled (see notepad-plus-plus/notepad-plus-plus#8916 (comment)) so I suppose it is appropriate to close this issue. :-(

My comment to that:

That doesn't fulfill the goal. What that does is pop-up a box and waits for the script user to "fill in the blank", and that's for a file that is going to be actually on disk.

What is wanted is a way to rename an unsaved tab, e.g. new 5, to something else (but still an unsaved tab, not on disk), without any user involvement.

This could be achieved using:
SendMessage(NPPM_INTERNAL_SETFILENAME, intptr_t bufferId, const char * newName);

Reopen?

Should pythonscript really rely on internal npp messages?
Are they not called internal because they should not be used by plugins?

No, I was just documenting it as a possible means. Since that time, the author of N++ has decided that the internal message itself should be removed, as it is unused (internally).

Oddly enough, the internal message in question seems to have been create for a plugin's usage.

Oh, I see, I was late for the party :-)

Impl of

	#define NPPM_SETUNTITLEDNAME (NPPMSG + 115)
	// int NPPM_SETUNTITLEDNAME(BufferID id, const wchar_t* newName)
	// Rename the tab name for an untitled tab.
	// wParam[in]: id - BufferID of the tab. -1 for currently active tab
	// lParam[in]: newName - the desired new name of the tab
	// Return TRUE upon success; FALSE upon failure

needed for this.
