- 
-Use 
---- 
- 
-ipdb exports functions to access the IPython_ debugger, which features 
-tab completion, syntax highlighting, better tracebacks, better introspection 
-with the same interface as the `pdb` module. 
- 
-Example usage: 
- 
-.. code-block:: python 
- 
-        import ipdb 
-        ipdb.set_trace() 
-        ipdb.set_trace(context=5)  # will show five lines of code 
-                                   # instead of the default three lines 
-                                   # or you can set it via IPDB_CONTEXT_SIZE env variable 
-                                   # or setup.cfg file 
-        ipdb.pm() 
-        ipdb.run('x[0] = 3') 
-        result = ipdb.runcall(function, arg0, arg1, kwarg='foo') 
-        result = ipdb.runeval('f(1,2) - 3') 
- 
- 
-Arguments for `set_trace` 
-+++++++++++++++++++++++++ 
- 
-The `set_trace` function accepts `context` which will show as many lines of code as defined, 
-and `cond`, which accepts boolean values (such as `abc == 17`) and will start ipdb's 
-interface whenever `cond` equals to `True`. 
- 
-Using configuration file 
-++++++++++++++++++++++++ 
- 
-It's possible to set up context using a `.ipdb` file on your home folder, `setup.cfg` 
-or `pyproject.toml` on your project folder. You can also set your file location via 
-env var `$IPDB_CONFIG`. Your environment variable has priority over the home 
-configuration file, which in turn has priority over the setup config file. 
-Currently, only context setting is available. 
- 
-A valid setup.cfg is as follows 
- 
-:: 
- 
-        [ipdb] 
-        context=5 
- 
- 
-A valid .ipdb is as follows 
- 
-:: 
- 
-        context=5 
- 
- 
-A valid pyproject.toml is as follows 
- 
-:: 
- 
-        [tool.ipdb] 
-        context=5 
- 
- 
-The post-mortem function, ``ipdb.pm()``, is equivalent to the magic function 
-``%debug``. 
- 
-.. _IPython: http://ipython.org 
- 
-If you install ``ipdb`` with a tool which supports ``setuptools`` entry points, 
-an ``ipdb`` script is made for you. You can use it to debug your python 2 scripts like 
- 
-:: 
- 
-        $ bin/ipdb mymodule.py 
- 
-And for python 3 
- 
-:: 
- 
-        $ bin/ipdb3 mymodule.py 
- 
-Alternatively with Python 2.7 only, you can also use 
- 
-:: 
- 
-        $ python -m ipdb mymodule.py 
- 
-You can also enclose code with the ``with`` statement to launch ipdb if an exception is raised: 
- 
-.. code-block:: python 
- 
-        from ipdb import launch_ipdb_on_exception 
- 
-        with launch_ipdb_on_exception(): 
-            [...] 
- 
-.. warning:: 
-   Context managers were introduced in Python 2.5. 
-   Adding a context manager implies dropping Python 2.4 support. 
-   Use ``ipdb==0.6`` with 2.4. 
- 
-Or you can use ``iex`` as a function decorator to launch ipdb if an exception is raised: 
- 
-.. code-block:: python 
- 
-        from ipdb import iex 
- 
-        @iex 
-        def main(): 
-            [...] 
- 
-.. warning:: 
-   Using ``from future import print_function`` for Python 3 compat implies dropping Python 2.5 support. 
-   Use ``ipdb<=0.8`` with 2.5. 
- 
-Issues with ``stdout`` 
----------------------- 
- 
-Some tools, like ``nose`` fiddle with ``stdout``. 
- 
-Until ``ipdb==0.9.4``, we tried to guess when we should also 
-fiddle with ``stdout`` to support those tools. 
-However, all strategies tried until 0.9.4 have proven brittle. 
- 
-If you use ``nose`` or another tool that fiddles with ``stdout``, you should 
-explicitly ask for ``stdout`` fiddling by using ``ipdb`` like this 
- 
-.. code-block:: python 
- 
-        import ipdb 
-        ipdb.sset_trace() 
-        ipdb.spm() 
- 
-        from ipdb import slaunch_ipdb_on_exception 
-        with slaunch_ipdb_on_exception(): 
-            [...] 
- 
- 
-Development 
------------ 
- 
-``ipdb`` source code and tracker are at https://github.com/gotcha/ipdb. 
- 
-Pull requests should take care of updating the changelog ``HISTORY.txt``. 
- 
-Under the unreleased section, add your changes and your username. 
- 
-Manual testing 
-++++++++++++++ 
- 
-To test your changes, make use of ``manual_test.py``. Create a virtual environment, 
-install IPython and run ``python manual_test.py`` and check if your changes are in effect. 
-If possible, create automated tests for better behaviour control. 
- 
-Automated testing 
-+++++++++++++++++ 
- 
-To run automated tests locally, create a virtual environment, install `coverage` 
-and run `coverage run setup.py test`. 
- 
-Third-party support 
-------------------- 
- 
-Products.PDBDebugMode 
-+++++++++++++++++++++ 
- 
-Zope2 Products.PDBDebugMode_ uses ``ipdb``, if available, in place of ``pdb``. 
- 
-.. _Products.PDBDebugMode: http://pypi.python.org/pypi/Products.PDBDebugMode 
- 
-iw.debug 
-++++++++ 
- 
-iw.debug_ allows you to trigger an ``ipdb`` debugger on any published object 
-of a Zope2 application. 
- 
-.. _iw.debug: http://pypi.python.org/pypi/iw.debug 
- 
-ipdbplugin 
-++++++++++ 
- 
-ipdbplugin_ is a nose_ test runner plugin that also uses the IPython debugger 
-instead of ``pdb``. (It does not depend on ``ipdb`` anymore). 
- 
-.. _ipdbplugin: http://pypi.python.org/pypi/ipdbplugin

+Arguments for `set_trace`
++++++++++++++++++++++++++
+
+The `set_trace` function accepts `context` which will show as many lines of code as defined,

+env var `$IPDB_CONFIG`. Your environment variable has priority over the home
+configuration file, which in turn has priority over the setup config file.
+Currently, only context setting is available.
+
+A valid setup.cfg is as follows
+
+::

-Use 
---- 
- 
-ipdb exports functions to access the IPython_ debugger, which features 
-tab completion, syntax highlighting, better tracebacks, better introspection 
-with the same interface as the `pdb` module. 
- 
-Example usage: 
- 
-.. code-block:: python 
- 
-        import ipdb 
-        ipdb.set_trace() 
-        ipdb.set_trace(context=5)  # will show five lines of code 
-                                   # instead of the default three lines 
-                                   # or you can set it via IPDB_CONTEXT_SIZE env variable 
-                                   # or setup.cfg file 
-        ipdb.pm() 
-        ipdb.run('x[0] = 3') 
-        result = ipdb.runcall(function, arg0, arg1, kwarg='foo') 
-        result = ipdb.runeval('f(1,2) - 3') 
- 
- 
-Arguments for `set_trace` 
-+++++++++++++++++++++++++ 
- 
-The `set_trace` function accepts `context` which will show as many lines of code as defined, 
-and `cond`, which accepts boolean values (such as `abc == 17`) and will start ipdb's 
-interface whenever `cond` equals to `True`. 
- 
-Using configuration file 
-++++++++++++++++++++++++ 
- 
-It's possible to set up context using a `.ipdb` file on your home folder, `setup.cfg` 
-or `pyproject.toml` on your project folder. You can also set your file location via 
-env var `$IPDB_CONFIG`. Your environment variable has priority over the home 
-configuration file, which in turn has priority over the setup config file. 
-Currently, only context setting is available. 
- 
-A valid setup.cfg is as follows 
- 
-:: 
- 
-        [ipdb] 
-        context=5 
- 
- 
-A valid .ipdb is as follows 
- 
-:: 
- 
-        context=5 
- 
- 
-A valid pyproject.toml is as follows 
- 
-:: 
- 
-        [tool.ipdb] 
-        context=5 
- 
- 
-The post-mortem function, ``ipdb.pm()``, is equivalent to the magic function 
-``%debug``. 
- 
-.. _IPython: http://ipython.org 
- 
-If you install ``ipdb`` with a tool which supports ``setuptools`` entry points, 
-an ``ipdb`` script is made for you. You can use it to debug your python 2 scripts like 
- 
-:: 
- 
-        $ bin/ipdb mymodule.py

-   Using ``from future import print_function`` for Python 3 compat implies dropping Python 2.5 support. 
-   Use ``ipdb<=0.8`` with 2.5. 
- 
-Issues with ``stdout`` 
----------------------- 
- 
-Some tools, like ``nose`` fiddle with ``stdout``.

+
+Use
+---
+
+ipdb exports functions to access the IPython_ debugger, which features
+tab completion, syntax highlighting, better tracebacks, better introspection
+with the same interface as the `pdb` module.
+
+Example usage:
+
+.. code-block:: python
+
+        import ipdb
+        ipdb.set_trace()
+        ipdb.set_trace(context=5)  # will show five lines of code
+                                   # instead of the default three lines
+                                   # or you can set it via IPDB_CONTEXT_SIZE env variable
+                                   # or setup.cfg file
+        ipdb.pm()
+        ipdb.run('x[0] = 3')
+        result = ipdb.runcall(function, arg0, arg1, kwarg='foo')
+        result = ipdb.runeval('f(1,2) - 3')
+
+
+Arguments for `set_trace`
++++++++++++++++++++++++++
+
+The `set_trace` function accepts `context` which will show as many lines of code as defined,
+and `cond`, which accepts boolean values (such as `abc == 17`) and will start ipdb's
+interface whenever `cond` equals to `True`.
+
+Using configuration file
+++++++++++++++++++++++++
+
+It's possible to set up context using a `.ipdb` file on your home folder, `setup.cfg`
+or `pyproject.toml` on your project folder. You can also set your file location via
+env var `$IPDB_CONFIG`. Your environment variable has priority over the home
+configuration file, which in turn has priority over the setup config file.
+Currently, only context setting is available.
+
+A valid setup.cfg is as follows
+
+::
+
+        [ipdb]
+        context=5
+
+
+A valid .ipdb is as follows
+
+::
+
+        context=5
+
+
+A valid pyproject.toml is as follows
+
+::
+
+        [tool.ipdb]
+        context=5
+
+
+The post-mortem function, ``ipdb.pm()``, is equivalent to the magic function
+``%debug``.
+
+.. _IPython: http://ipython.org
+
+If you install ``ipdb`` with a tool which supports ``setuptools`` entry points,
+an ``ipdb`` script is made for you. You can use it to debug your python 2 scripts like
+
+::
+
+        $ bin/ipdb mymodule.py
+
+And for python 3
+
+::
+
+        $ bin/ipdb3 mymodule.py
+
+Alternatively with Python 2.7 only, you can also use
+
+::
+
+        $ python -m ipdb mymodule.py
+
+You can also enclose code with the ``with`` statement to launch ipdb if an exception is raised:
+
+.. code-block:: python
+
+        from ipdb import launch_ipdb_on_exception
+
+        with launch_ipdb_on_exception():
+            [...]
+
+.. warning::
+   Context managers were introduced in Python 2.5.
+   Adding a context manager implies dropping Python 2.4 support.
+   Use ``ipdb==0.6`` with 2.4.
+
+Or you can use ``iex`` as a function decorator to launch ipdb if an exception is raised:
+
+.. code-block:: python
+
+        from ipdb import iex
+
+        @iex
+        def main():
+            [...]
+
+.. warning::
+   Using ``from future import print_function`` for Python 3 compat implies dropping Python 2.5 support.
+   Use ``ipdb<=0.8`` with 2.5.
+
+Issues with ``stdout``
+----------------------
+
+Some tools, like ``nose`` fiddle with ``stdout``.
+
+Until ``ipdb==0.9.4``, we tried to guess when we should also
+fiddle with ``stdout`` to support those tools.
+However, all strategies tried until 0.9.4 have proven brittle.
+
+If you use ``nose`` or another tool that fiddles with ``stdout``, you should
+explicitly ask for ``stdout`` fiddling by using ``ipdb`` like this
+
+.. code-block:: python
+
+        import ipdb
+        ipdb.sset_trace()
+        ipdb.spm()
+
+        from ipdb import slaunch_ipdb_on_exception
+        with slaunch_ipdb_on_exception():
+            [...]
+
+
+Development
+-----------
+
+``ipdb`` source code and tracker are at https://github.com/gotcha/ipdb.
+
+Pull requests should take care of updating the changelog ``HISTORY.txt``.
+
+Under the unreleased section, add your changes and your username.
+
+Manual testing
+++++++++++++++
+
+To test your changes, make use of ``manual_test.py``. Create a virtual environment,
+install IPython and run ``python manual_test.py`` and check if your changes are in effect.
+If possible, create automated tests for better behaviour control.
+
+Automated testing
++++++++++++++++++
+
+To run automated tests locally, create a virtual environment, install `coverage`
+and run `coverage run setup.py test`.
+
+Third-party support
+-------------------
+
+Products.PDBDebugMode
++++++++++++++++++++++
+
+Zope2 Products.PDBDebugMode_ uses ``ipdb``, if available, in place of ``pdb``.
+
+.. _Products.PDBDebugMode: http://pypi.python.org/pypi/Products.PDBDebugMode
+
+iw.debug
+++++++++
+
+iw.debug_ allows you to trigger an ``ipdb`` debugger on any published object
+of a Zope2 application.
+
+.. _iw.debug: http://pypi.python.org/pypi/iw.debug
+
+ipdbplugin
+++++++++++
+
+ipdbplugin_ is a nose_ test runner plugin that also uses the IPython debugger
+instead of ``pdb``. (It does not depend on ``ipdb`` anymore).
+
+.. _ipdbplugin: http://pypi.python.org/pypi/ipdbplugin
