<!-- TITLE: implementing goto statements in python (in under 50 lines)-->

python is extremely extensible, though I'm not sure that is intentional.

<hr>
|
||||
now then, how does it work?
|
||||
<h3>design decisions</h3>
|
||||
given that evidence suggests python programs can be edited, I decided not to use line number based gotos and instead define labels that could be jumped to.
|
||||
this makes things less annoying to edit and maintain, and developer experience is obviously a very important consideration with this project.<br>
|
||||
additionally, to maximize ease with which this ""library"" can be utilized, one must only import the file to experience the wonder of python with goto statements.
|
||||
<h3>technical implementation</h3>
|
||||
firstly, labels: <br>
|
||||
goto_label.py has a function prepare_labels(fp, scope).
|
||||
this function looks for any labels (defined via /^#LABEL labelname/) in the file at fp, and defines them under the scope scope.
|
||||
each label is defined as a label object. I resent using an object for this (which you can see by my not using the class keyword), but python is python and you cannot override operators without having a class.
|
||||
I could just not override the operators, but I want goto to be called in a unique way that is separate from how a function would be called.
|
||||
label objects have only one attribute: lineno, which is determined by an extremely rudimentary parser and then offset by 2 to account for the fact that lines are 0 indexed in the "parser" but not in real life and the fact that the label definition comment takes its own line.
|
||||
<br><br>
|
||||
the actual goto implementation:<br>
|
||||
I don't remember how this works because I wrote most of the _goto function like 3 months ago after reading the sys and inspect module docs.
|
||||
my projects have this fun property where they are in one of three states: done; not touched or thought about for 2-36 months; and done.
|
||||
oh well, the goto function is vaguely self explanatory anyways.
|
||||
<br>
|
||||
there is some weirdness with operator overloading and how every goto statement is actually just calling what would normally be the bitwise and operator on an instance of the class _goto (not to be confused with the function _goto) and a label object, but that is both very simple and not required to understand this.<br>
|
||||
also, I don't want to explain it because I am tired.
|
||||
<br><br>
|
||||
automatically parsing the importing file on import:<br>
|
||||
normally, globals are not shared between modules, but python has this cool feature where if there is a general statement to be made about it then this statement can be invalidated using either the sys, inspect, or ctypes library.
|
||||
this is easily the simplest part as we just grab the filename and global scope of the importing file via the inspect library and pass them to prepare_labels().

I find much enjoyment in the syntax for calling a goto statement being goto &label. it looks like something that thoroughly does not belong in python.
|
||||
<br><br>
|
||||
ideas for future improvement:
|
||||
making label names override builtin function names (unreasonably possible) and making a __call__ method on label objects that jumps to that label.
|
||||
hopefully no one creates any labels named "print".
|
