[Eric] running and debugging programs remotely (on lan)

[RICHARD Georges-Emmanuel]

Hi Vincent,
   after reading your topic about remote debugging, I wonder if you 
managed to go the way you described, if so can you provide some feedback 
about your experience of remote debugging.
Up to now I managed to use:
- local debug  (I mean the default setting), you load a python script 
then use F5 to start the debugging session (which is the easiest way, 
and thanks again for Detlev to provide such a great IDE)
- passive debugging (let you start the debugging session from outside of 
Eric4), you first setup Eric4 -> Settings/Debug/General  check the 
passive mode, then restart Eric4, it will then be pending until you 
start from a shell (local or another computer) the debug client with 
your program as argument
                 python2.5 DebugClient.py -h 192.168.1.3 -- 
/root/MyProject/script/test.py
my script is executed and wait on the first line to continue the debug, 
all debugging functions are available (step_over, continue, until 
cursor, step out,..)

I admit, it's quiet good.
For my case instead of running the DebugClient.py (in command line) , I 
would like to start the debugging session directly from my program test.py.

I started to embedd those few lines, the program stop just after as I 
needed, all debugging functions are not available (ie: continue, and 
until cursor same behaviour as step over):

(I copied the eric4 DebugClient module into dbg_client a folder in my 
project to debug)

test.py:
     import os,sys
     print "Running program"
(...)
     import dbg_client.DebugClient
     DBG=dbg_client.DebugClient.DebugClient()
     DBG.startDebugger(host= '192.168.1.3',port= 42424,exceptions=True, 
enableTrace=True ,redirect=True) # 192.168.1.3 the IP address where 
Eric4 is running in passive mode
     print "Eric4 debugging yellow line is positionned here, and that's 
great"
(...)
     print "Debugger Started"

My next point is to use the Remote debugging option of Eric4, and try to 
see if it could match an easier way of usage, but no real idea how to 
handle the setup for now.


In advance thanks.
                             Joe
