System Requirements

-------------------

This module requires Python version 3.8 or higher in order to run. Similar to Tcl requirements, Eggdrop requires both python and python development libraries to be installed on the host machine. On Debian/Ubuntu machines, this means the packages ``python``, ``python-dev`` AND ``python-is-python3`` to be installed. The python-is-python3 updates symlinks on the host system that allow Eggdrop to find it.

The ``pysource`` command is analogous to the Tcl ``source`` command, except that it loads a Python script into Eggdrop instead of a Tcl script.

Eggdrop Python Commands
56
-
-----------------------
57
-
58
-
The Python module is built to use the existing core Tcl commands integrated into Eggdrop via the ``eggdrop.tcl`` module. To call an existing Tcl command from Python, you can either load the entire catalog by running ``import eggdrop.tcl``, or be more specific by ``from eggdrop.tcl import putserv, putlog, chanlist``, etc.
59
-
60
-
Arguments to the Tcl functions are automatically converted as follows:
61
-
62
-
* ``None`` is converted to an empty Tcl object (the empty string, ``""``)
63
-
* ``List`` and ``Tuple`` is converted to a ``Tcl list``
64
-
* ``Dict`` is converted to a ``Tcl dictionary``
65
-
* Everything else is converted to a string using the str() method
66
-
67
-
Return values from Tcl functions must be manually converted:
68
-
69
-
* ``""`` the empty string is automatically converted to None
70
-
* everything else is returned as string
71
-
* ``Tcl list`` as string can be converted to a Python ``List`` using ``parse_tcl_list``
72
-
* ``Tcl dictionary`` as string can be converted to a Python ``Dict`` using ``parse_tcl_list``
73
-
74
-
Additionally, a few extra python commands have been created for use without these conversions:
75
-
76
-
^^^^^^^^^^^^^^^^
77
-
bind <arguments>
78
-
^^^^^^^^^^^^^^^^
79
-
80
-
The python version of the bind command is used to create a bind that triggers a python function. The python bind takes the same arguments as the Tcl binds, but here each argument is passed individually. For example, a bind that would look like ``bind pub * !foo myproc`` in Tcl is written as ``bind("pub", "*", "!foo", myproc)``. For more information on Eggsrop bind argument syntax please see :ref:`bind_types`. The eggdrop.tcl.bind command should not be used as it will attempt to call a Tcl proc.
81
-
82
-
^^^^^^^^^^^^^^^^^^^^^^^
83
-
parse_tcl_list <string>
84
-
^^^^^^^^^^^^^^^^^^^^^^^
85
-
86
-
When a python script calls a Tcl command that returns a list via the eggdrop.tcl module, the return value will be a Tcl-formatted list- also simply known as a string. The ``parse_tcl_list`` command will convert the Tcl-formatted list into a Python list, which can then freely be used within the Python script.
87
-
88
-
^^^^^^^^^^^^^^^^^^^^^^^
89
-
parse_tcl_dict <string>
90
-
^^^^^^^^^^^^^^^^^^^^^^^
91
-
92
-
When a python script calls a Tcl command that returns a dict via the eggdrop.tcl module, the return value will be a Tcl-formatted dict- also simply known as a string. The ``parse_tcl_dict`` command will c
93
-
onvert the Tcl-formatted dict into a Python list, which can then freely be used within the Python script.

There are also some variables you can set in your config file:
100
-
101
-
set allow-resync 0
102
-
When two bots get disconnected, this setting allows them to create a
103
-
resync buffer which saves all changes done to the userfile during
104
-
the disconnect. When they reconnect, they will not have to transfer
105
-
the complete user file, but, instead, just send the resync buffer.

To load a python script from your config file, place the .py file in the scripts/ folder and add the following line to your config::

38

39

* ``""`` the empty string is automatically converted to None
40

* everything else is returned as string
41

An important difference to note is that Eggdrop Python has its own ``bind`` command implemented. You will generally want to create binds using the Python ``bind`` command and not import bind from eggdrop.tcl because a Python bind will call a Python function, whereas using the Tcl bind will call a Tcl function (not one from the script you are writing).
49

50

The python version of the bind command is used to create a bind that triggers a python function. The python bind takes the same arguments as the Tcl binds, but here each argument is passed individually. For example, a bind that would look like ``bind pub * !foo myproc`` in Tcl is written as ``bind("pub", "*", "!foo", myproc)``. For more information on Eggsrop bind argument syntax please see :ref:`bind_types`. The eggdrop.tcl.bind command should not be used as it will attempt to call a Tcl proc.

Python is able to call any Tcl command by importing the ``eggdrop`` module. For example, to use the ``putlog`` command in a python script, you would import it as::
94
+
95
+
from eggdrop.tcl import putlog
96
+
97
+
and then call it using::
98
+
99
+
putlog("This is a logged message")
