1 README for passive mode debugging
2 =================================
3
4 eric6 provides the capability to debug programms using the passive
5 mode. In this mode it is possible to start the debugger separate from
6 the IDE. This may be done on a different computer as well. If the
7 debugger is started on a remote machine, it is your responsibility
8 to ensure, that the paths to the script to be debugged are identical
9 on both machines.
10
11 In order to enable passive mode debugging in the IDE choose the
12 debugger tab of the preferences dialog and enable the passive mode
13 debugging checkbox. You may change the default port as well. Please
14 be aware that you have to tell the debugger the port, if it is different
15 to the default value of 42424.
16
17 On the remote computer you have to have the debugger scripts installed.
18 Use DebugClient.py to debug normal and multi threaded scripts. The debugger
19 knows about the following commandline switches.
20
21 ::
22
23 -h <hostname>
24 This specifies the hostname of the machine running the IDE.
25 -p <portnumber>
26 This specifies the portnumber of the IDE.
27 -w <directory>
28 This specifies the working directory to be used for the script
29 to be debugged.
30 -t
31 This enables tracing into the Python library.
32 -n
33 This disables the redirection of stdin, stdout and stderr.
34 -e
35 This disables reporting of exceptions.
36 --fork-child
37 This tells the debugger to follow the child when forking.
38 --fork-parent
39 This tells the debugger to follow the parent when forking
40
41 The commandline parameters have to be followed by ``'--'`` (double dash),
42 the script to be debugged and its commandline parameters.
43
44 Example::
45
46 python DebugClient -h somehost -- myscript.py param1
47
48 After the execution of the debugger command, it connects to the IDE and
49 tells it the filename of the script being debugged. The IDE will try to
50 load it and the script will stop at the first line. After that you may set
51 breakpoints, step through your script and use all the debugging functions.
52
53 Note: The port and hostname may alternatively be set through the environment
54 variables ERICPORT and ERICHOST.

56 Please send bug reports, feature requests or contributions to eric bugs address
57 <eric-bugs@die-offenbachs.de> or using the buildt in bug reporting dialog.
