-Python Console
-******************
-
-**Python console** - Window for Python interpreter. This window functions like a standard document:
-the pop-up menu invoked by right-click in this window gives access to **Copy/Paste/SelectAll/ClearAll** options.
-
-You can run a Python script in interactive mode by typing expressions line by line or by loading a Python file
-from the main menu **File -> Load Script**.
-
-==================
-Asynchronous mode
-==================
-
-By default the console is always initialized in asynchronous mode when the Python commands are executed in the separated thread
-that does not block the main GUI loop. So, you'll see any intermediate output from the running script even if the script didn't finish yet.
-
-In the synchronous mode each Python command is executed in the main GUI thread, then GUI is blocked until the command is finished.
-It could be an issue if you run a time consuming Python script, because you won't see any output till the end of execution.
-
-If you need to run a script in synchronous mode for whatever reason, set ``PYTHON_CONSOLE_SYNC`` environment variable before Salome start:
-
-.. code-block:: console
-
- export PYTHON_CONSOLE_SYNC=1
-
-==================
-Tracing
-==================
-
-To output in console currently executed functions, we're adding tracing code to the start and at the end
-of the command to deactivate it immediately after execution.
-
-This mechanism is turned off by default. Set ``PYCONSOLE_TRACE`` before SALOME start to activate it:
-
-.. code-block:: console
-
- export PYCONSOLE_TRACE=1
-
-If the tracing is on while the script is running we can see functions enter and return calls
-with ``>>`` and ``<<`` marks followed by line number and function name. Tracing function prints only calls to functions
-defined in the current script to prevent printing of thousands of lines for builtin functions in some cases.
-
-Example of a script with defined functions:
-
-.. code-block:: python
- :linenos:
-
- #!/usr/bin/env python
-
- import time
-
- def sum(x, y):
- time.sleep(3)
- return x + y
-
- def sub(x, y):
- time.sleep(3)
- return x - y
-
- def prod(x, y):
- time.sleep(3)
- return x * y
-
- def div(x, y):
- time.sleep(3)
- return x / y
-
- x = 5
- y = 2
-
- sum(x, y)
- sub(x, y)
- prod(x, y)
- div(x, y)
-
-And output in the Python console:
-
-.. code-block:: console
-
- >>> sys.setprofile(lambda frame, event, arg: print('>>', frame.f_lineno, ': ', frame.f_code.co_name) if event == 'call' and frame.f_code.co_filename == '/home/function_calls.py' and frame.f_code.co_name != '<module>' else print('<<', frame.f_lineno, ': ', frame.f_code.co_name) if event == 'return' and frame.f_code.co_filename == '/home/function_calls.py' and frame.f_code.co_name != '<module>' else None); exec(compile(open('/home/function_calls.py', 'rb').read(), '/home/function_calls.py', 'exec')); sys.setprofile(None);
- >> 5 : sum
- << 7 : sum
- >> 9 : sub
- << 11 : sub
- >> 13 : prod
- << 15 : prod
- >> 17 : div
- << 19 : div
- >>>
