Nope it is the other way around!
You first have to launch the debug config in Eclipse, it opens a debugging server and the script you later launch from the command line then connects to it!

If you feel it needs clarification in the documentation on the Wiki, feel free to update accordingly... :)

One more thing, you should make sure to actually append the name of the script you want to debug, on your commandline ; for example:
lua -e "require('debugger')();" MyApp.lua
According to your previous messages, I am not sure you did that, and this might explain a few things :)
Cheers!

Hi Benjamin,

I have it now running.

I appended my lua application to the commandline already.

But the reason why I thougt it is the other way round was that when I try to start the debug configuration from eclipse I run into a timeout.

But that is no problem, the only thing I have to do is to start

lua -e "require('debugger')();" MyApp.lua

fast enough from the commandline, after I started the debug configuration.

Thank you very much for your help :)

Volker

You can also increase the default timeout in the debug config settings :)

There is more than enough time to start lua -e "require('debugger')();" MyApp.lua.

But I waited every time for something like a success message after I started the debug config.

In the meantime I think I know why os.getenv("PWD") is not working. I think the reason is that when the command gets started from the program there is no $PWD variable in that context.

I changed now the line

base_dir = os.getenv("PWD")

to:

local file_name = debug.getinfo(1).short_src
local p = io.popen("dirname $(readlink -f " .. file_name .. ")")
if p then
base_dir = p:read("*l")
p:close()
end

which worked for me.
