vascorsd<p>It's always sad when reading comments on <a href="https://mastodon.social/tags/fp" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fp</span></a> languages and people saying "I tried <a href="https://mastodon.social/tags/ocaml" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ocaml</span></a>, <a href="https://mastodon.social/tags/haskell" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>haskell</span></a>, <a href="https://mastodon.social/tags/fsharp" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fsharp</span></a>... and don't like because X", which shows they are interested but then also say "I looked at <a href="https://mastodon.social/tags/scala" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>scala</span></a> and it looked complex so I didn't even try it and ran away" 🙃...</p><p>People, if you can do it in those languages, you can do it in scala.

arialdo<p><a href="https://mastodon.online/tags/fsharp" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fsharp</span></a> does not support function overload.

It's horribly convoluted.</p><p>I guess I'm soon writing a blob post with all the steps to get there.</p>
brandewinder<p>After an annoying work day that started with waking up unpleasantly early to attend a meeting which did not take place, and continued along the same vein, I needed to feel like I actually did something today, and wrote some more Delaunay triangulation code. It ended up much easier than what I thought - it's actually almost done. <a href="https://hachyderm.io/tags/fsharp" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fsharp</span></a></p>
arialdo<p>I’m fascinated by Free Monads. <a href="https://mastodon.online/tags/fsharp" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fsharp</span></a></p>
arialdo<p>In the attempt to grasp monad transformers, I'm reading Grokking Monads by Matt Thornton (can't find him here on Mastodon)</p><p>It's a very well written series, <a href="https://mastodon.online/tags/fsharp" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fsharp</span></a> based, and I would recommend it as a first read about monads.</p><p><a href="https://dev.to/choc13/grokking-monads-in-f-3j7f" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">dev.to/choc13/grokking-monads-</span><span class="invisible">in-f-3j7f</span></a></p>
arialdo<p>The trait that I initially hated the most about <a href="https://mastodon.online/tags/fsharp" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fsharp</span></a>, the compilation order, quickly turned out to be among those I love the most. It forces me to think and to care about design.</p><p>Lovely.</p>
arialdo<p>I would like to give back to 2 projects that gave me a lot, <a href="https://mastodon.online/tags/Emacs" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Emacs</span></a> and <a href="https://mastodon.online/tags/fsharp" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fsharp</span></a>.</p><p>Since it seems there is not a comprehensive Tree-sitter mode for F# yet, I gave myself the (long term) challenge to learn enough about <a href="https://mastodon.online/tags/Tree" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Tree</span></a>-sitter, major modes, <a href="https://mastodon.online/tags/LSP" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LSP</span></a> and the like to write one (or at least to contribute to one).</p><p>Along the way, I promised myself to share in blog posts what I happen to learn.</p><p>Here's a first article with the notes taken while wrapping my head around Imenu.</p><p><a href="https://arialdomartini.github.io/emacs-imenu" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">arialdomartini.github.io/emacs</span><span class="invisible">-imenu</span></a></p>
