+# Short hyperlinks to Python docs
+Eduardo Ochs
+
+[[!inline pages="internal(2022/info/python-before)" raw="yes"]]
+
+If we have a local copy of the Python docs installed then it is easy
+to define the three hyperlink functions in the Python program below,
+
+    # (find-pydoc  "tutorial/classes")
+    # (find-pydocw "tutorial/classes")
+    # (find-pydocr "tutorial/classes")
+    class MyVector:
+        def __init__(v, x, y):
+            v.x = x
+            v.y = y
+
+such that each one expands its argument in the right way, and the
+first one opens the local URL
+<file:///usr/share/doc/python3.9-doc/html/tutorial/classes.html> in
+the browser, the
+second one opens <https://docs.python.org/3/tutorial/classes.html>, and
+the third one opens the RST source of those HTML pages in Emacs: the
+file `/<rstsourcedir>/tutorial/classes.rst.txt`.
+
+The docs for Python are designed to be navigated in a browser. Suppose
+that we start on the page
+[classes.html](https://docs.python.org/3/tutorial/classes.html)
+above, follow a couple of
+hyperlinks, and then we find this other page that, ahem, is very
+interesting and important and we *need* to have hyperlinks to:
+
+<https://docs.python.org/3/reference/datamodel.html#object.__init__>
+
+The most obvious way to create elisp hyperlinks to that page is to
+copy its URL to Emacs, edit it by hand to produce a `(find-pydoc ...)`
+hyperlink, duplicate that hyperlink twice, and add a "`w`" and a "`r`"
+into the right places&#x2026; but this is not very practical.
+
+In this presentation I will show a practical way to handle that. It is
+a new module of eev &#x2013;
+[eev-rstdoc.el](http://angg.twu.net/eev-current/eev-rstdoc.el.html)
+&#x2013; that performs both the
+expansions needed by `find-pydoc{,w,r}` and the "shrinkings" that
+convert URLs and filenames to short hyperlinks. Eev-rstdoc.el comes
+with three "families" of hyperlinks, expansions, and shrinkings: one
+for Python docs, one for SymPy, and one for MatPlotLib. It is easy to
+add new families, and the parameters for expansion and shrinking in
+each family are easy to configure.
+
+For more info see [this
+page](http://angg.twu.net/emacsconf2022-py.html). For a translation of the Python tutorial
+to a format that has only executable examples and elisp hyperlinks,
+see [this](http://angg.twu.net/e/python.e.html#tut-numbers).
