<h1>Les snippets dans LazyVim</h1>

<div class="content">
<p>Aujourd’hui je viens de tester l’utilisation des snippets dans LazyVim (il y aura un prochain billet sur la configuration de mon environnement d’écriture.).</p>
<p>Pour faire des snippets rien de plus simple ! Il suffit de charger le plugin LuaSnip (merci au fil de <a href="https://github.com/LazyVim/LazyVim/discussions/54">discussion</a>) :</p>
<div class="sourceCode" id="cb1"><pre class="sourceCode lua"><code class="sourceCode lua"><span id="cb1-1"><a href="#cb1-1" aria-hidden="true" tabindex="-1"></a> <span class="op">{</span></span>
<span id="cb1-2"><a href="#cb1-2" aria-hidden="true" tabindex="-1"></a> <span class="st">"L3MON4D3/LuaSnip"</span><span class="op">,</span></span>
<span id="cb1-3"><a href="#cb1-3" aria-hidden="true" tabindex="-1"></a> <span class="va">config</span> <span class="op">=</span> <span class="kw">function</span><span class="op">()</span></span>
<span id="cb1-4"><a href="#cb1-4" aria-hidden="true" tabindex="-1"></a> <span class="fu">require</span><span class="op">(</span><span class="st">"luasnip.loaders.from_lua"</span><span class="op">).</span>load<span class="op">({</span> <span class="va">paths</span> <span class="op">=</span> <span class="st">"~/.config/nvim/snippets"</span> <span class="op">})</span></span>
<span id="cb1-5"><a href="#cb1-5" aria-hidden="true" tabindex="-1"></a> <span class="kw">end</span><span class="op">,</span></span>
<span id="cb1-6"><a href="#cb1-6" aria-hidden="true" tabindex="-1"></a> <span class="op">},</span></span></code></pre></div>
<p>puis d’ajouter les snippets en LUA dans le dossier donné dans le chemin ci-dessus.</p>
<p>Pour mon premier snippet, j’ai créé un noeud texte pour générer le YAML des posts de ce blog.</p>
<div class="sourceCode" id="cb2"><pre class="sourceCode lua"><code class="sourceCode lua"><span id="cb2-1"><a href="#cb2-1" aria-hidden="true" tabindex="-1"></a><span class="kw">local</span> <span class="va">ls</span> <span class="op">=</span> <span class="fu">require</span><span class="op">(</span><span class="st">"luasnip"</span><span class="op">)</span></span>
<span id="cb2-2"><a href="#cb2-2" aria-hidden="true" tabindex="-1"></a><span class="kw">local</span> <span class="va">s</span> <span class="op">=</span> <span class="va">ls</span><span class="op">.</span><span class="va">snippet</span></span>
<span id="cb2-3"><a href="#cb2-3" aria-hidden="true" tabindex="-1"></a><span class="kw">local</span> <span class="va">t</span> <span class="op">=</span> <span class="va">ls</span><span class="op">.</span><span class="va">text_node</span></span>
<span id="cb2-4"><a href="#cb2-4" aria-hidden="true" tabindex="-1"></a></span>
<span id="cb2-5"><a href="#cb2-5" aria-hidden="true" tabindex="-1"></a><span class="cf">return</span> <span class="op">{</span></span>
<span id="cb2-6"><a href="#cb2-6" aria-hidden="true" tabindex="-1"></a> <span class="co">-- Example of a multiline text node</span></span>
<span id="cb2-7"><a href="#cb2-7" aria-hidden="true" tabindex="-1"></a> s<span class="op">({</span><span class="va">trig</span> <span class="op">=</span> <span class="st">"@post"</span><span class="op">,</span> <span class="va">dscr</span> <span class="op">=</span> <span class="st">"return yaml for posts on my blog."</span><span class="op">},</span></span>
<span id="cb2-8"><a href="#cb2-8" aria-hidden="true" tabindex="-1"></a> <span class="op">{</span></span>
<span id="cb2-9"><a href="#cb2-9" aria-hidden="true" tabindex="-1"></a> t<span class="op">({</span><span class="st">"---"</span><span class="op">,</span> <span class="st">"title: ''"</span><span class="op">,</span> <span class="st">"date:"</span><span class="op">,</span> <span class="st">"---"</span><span class="op">})</span></span>
<span id="cb2-10"><a href="#cb2-10" aria-hidden="true" tabindex="-1"></a> <span class="op">}</span></span>
<span id="cb2-11"><a href="#cb2-11" aria-hidden="true" tabindex="-1"></a> <span class="op">),</span></span>
<span id="cb2-12"><a href="#cb2-12" aria-hidden="true" tabindex="-1"></a> <span class="op">}</span></span></code></pre></div>
<p>C’est aussi simple que ça ! Il me suffit d’appeler le déclencheur <code>@post</code> pour voir apparaître mes 3 lignes de YAML :-)</p>
