Launching Lua

[John Hearle]

Okay so I have made a new Name.Lua file, and put the correct directory for Lua.exe in the launch command.
I also tried clarifying cmd /c and /k.

I can not get NPP to open CMD, and auto paste/run the code.

It will open CMD and not paste anything, meaning every time I want to run I have to copy and paste the whole thing by hand.

I even tried making a .bat file to open Lua.exe and did not work.

I copied videos exactly, still nothing.
I get error code 2: cannot find file specified, and it shows me both directories for Lua and CURRENT_FILE_PATH so I don’t know how it can’t find them.

I am noob to NPP just trying to set it up.

@John-Hearle ,

I get error code 2: cannot find file specified, and it shows me both directories for Lua and CURRENT_FILE_PATH so I don’t know how it can’t find them.

$(CURRENT_FILE_PATH) is not listed in the special run-command variables in the user manual.

It does not “auto paste”. You have to give the Run… command an argument to tell it exactly what you want to run.

Run > Run… > cmd /c "c:\path with spaces\to\lua.exe" "$(FULL_CURRENT_NAME)" should properly run the active file name using lua.exe (or use cmd /k if you want it to keep the cmd window open)

If you could show some of the example Run lines you have tried, I might be able to further explain why those weren’t sufficient, if I haven’t already explained it to your satisfaction.

We have a FAQ on how to run the active file through a compiler (which works equally well for an interpreter; that’s how I have Notepad++ set up to run the perl programs that I write).

edit 2: FULL_CURRENT_NAME is wrong; see later post below for correction

[John Hearle]

I already tried that, it just opens CMD and gives me C:Program files/Notepad++>

with the > symbol on end but nothing more, or it closes instantly.

@John-Hearle ,

You need to give me something. Copy/paste the exact commands you are using; use Alt+PrintScreen to show the command window. Something.

Because if you have a valid path to lua, if you use quotes the way I showed, and if the normal way to run a lua script from the command line is lua.exe scriptname.lua, then the example I showed should have worked.

@PeterJones said in Launching Lua:

cmd /c "c:\path with spaces\to\lua.exe" "$(FULL_CURRENT_NAME)"

Ugh. I meant cmd /c "c:\path with spaces\to\lua.exe" "$(FULL_CURRENT_PATH)" – don’t know how I got that wrong, since I’d provided the link to the full list of valid variables and everything. :-(

@PeterJones said in Launching Lua:

$(FULL_CURRENT_PATH)

I never remember this kind of stuff, so…

I have a Run menu command – saved as NPP $(XXX) vars echo (file info) – that gives me an example when I need it:

cmd /c echo FULL_CURRENT_PATH=$(FULL_CURRENT_PATH) CURRENT_DIRECTORY=$(CURRENT_DIRECTORY) FILE_NAME=$(FILE_NAME) NAME_PART=$(NAME_PART) EXT_PART=$(EXT_PART) && pause

Sample output:

After running, I can copy the FULL_CURRENT_PATH – or whatever text – from the cmd window, so not only do I NOT have to remember the names, I never have to type them either.

Later edit:

However, I can’t actually echo the verbatim text $(FULL_CURRENT_PATH) to the cmd window, because Notepad++ will hijack that and replace it. This could be “fixed” (see https://github.com/notepad-plus-plus/notepad-plus-plus/issues/9567) but perhaps doubtful that it ever will be.
