Paul McGuire<p>Some things I'm especially proud of in plusminus (my Python package for parsing and evaluating infix notation arithmetic):<br>- |absolute value| expressions<br>- ° symbol as a unary postfix operator, to convert degrees to radians: sin(π/2) vs. sin(90°)<br>- exponents ² and ³<br>- √ and ³√ operators (both unary and binary, so you can write 2√2)<br>- mathematical constants e, π, φ, and τ<br>- set operators ∈, ∉, ∩, and ∪<br>- safe eval of untrusted inputs <br>Try it at <a href="https://ptmcg.pythonanywhere.com/plusminus" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">ptmcg.pythonanywhere.com/plusm</span><span class="invisible">inus</span></a><br><a href="https://fosstodon.org/tags/python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>python</span></a> <a href="https://fosstodon.org/tags/parsing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>parsing</span></a> <a href="https://fosstodon.org/tags/infix" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>infix</span></a></p>

Samantha (Horny arc) 🎀 🏳️‍⚧️ 🔞<p>I'll actually just make my recursive descent parser module a whole new project. I think it deserves that. Perhaps other people need to parse config files and want to use my kick-ass grammar for it.
