    <h4 name="subtitle" id="subtitle" class="graf--h4">How to make syntax highlighting  more useful</h4>

<p class="graf--p graf--empty"><br/></p>

<p name="6fcb" id="6fcb" class="graf--p">This is what syntax highlighting looks like for most of us.</p>

<figure name="6d71" id="6d71" class="graf--figure"><div class="aspectRatioPlaceholder is-locked"><p class="aspect-ratio-fill"/><img class="graf-image" data-image-id="1*CTbkJuYm0JUcHFTAgovAsg.png" data-width="563" data-height="440" src="https://cdn-images-1.medium.com/max/800/1*CTbkJuYm0JUcHFTAgovAsg.png"/></div><figcaption class="imageCaption">This is javascript for the Fisher-Yates shuffle, which I took from this <a href="http://stackoverflow.com/questions/2450954/how-to-randomize-shuffle-a-javascript-array" data-href="http://stackoverflow.com/questions/2450954/how-to-randomize-shuffle-a-javascript-array" class="markup--anchor markup--figure-anchor" rel="nofollow">StackOverflow question</a>. Screenshot from Sublime Text 2 with the Dawn theme.</figcaption></figure>

<p name="4399" id="4399" class="graf--p">We think syntax highlighting makes the structure of code easier to understand. But as it stands, we highlight the obvious (like the word <em class="markup--em markup--p-em">function</em>) and leave most of the content in black. Rather than highlighting the differences between <em class="markup--em markup--p-em">currentIndex </em>and the keyword <em class="markup--em markup--p-em">function</em>, we could highlight the difference between <em class="markup--em markup--p-em">currentIndex</em> and <em class="markup--em markup--p-em">randomIndex</em>. Here’s what that might look like:</p>

<figure name="1b7e" id="1b7e" class="graf--figure"><div class="aspectRatioPlaceholder is-locked"><p class="aspect-ratio-fill"/><img class="graf-image" data-image-id="1*TVSPOYO1z8GOVs3tuxNRqA.png" data-width="563" data-height="440" src="https://cdn-images-1.medium.com/max/800/1*TVSPOYO1z8GOVs3tuxNRqA.png"/></div></figure>

<p name="589d" id="589d" class="graf--p">Notice that instead of the built-in keywords being highlighted, everything else is. Each variable has its own color, so I can see where it’s used at a glance. Even when skimming the code, I can see how data flows through the function.</p>

<p name="4164" id="4164" class="graf--p">By using only muted colors and bolder type for variable names, we can still reserve a brighter red to highlight strings and a lighter green for comments without causing confusion. Also, because any new or custom function will get a color, I’ll be able to catch the typo in <em class="markup--em markup--p-em">querySelector</em> below.</p>

<figure name="eb27" id="eb27" class="graf--figure"><div class="aspectRatioPlaceholder is-locked"><p class="aspect-ratio-fill"/><img class="graf-image" data-image-id="1*BxDY65qb-9LmvocCNvrLVg.png" data-width="422" data-height="106" src="https://cdn-images-1.medium.com/max/800/1*BxDY65qb-9LmvocCNvrLVg.png"/></div></figure>

<p name="08bb" id="08bb" class="graf--p">Variable names with similar prefixes will be assigned similar colors. We collect all the custom names and order them alphabetically, then distributing them evenly along a spectrum. This way we make sure we use as distinct colors as possible.</p>

<figure name="7da8" id="7da8" class="graf--figure"><div class="aspectRatioPlaceholder is-locked"><p class="aspect-ratio-fill"/><img class="graf-image" data-image-id="1*_eIcZ4gHFBrb5LycNrSI6g.png" data-width="979" data-height="226" data-action="zoom" data-action-value="1*_eIcZ4gHFBrb5LycNrSI6g.png" src="https://cdn-images-1.medium.com/max/800/1*_eIcZ4gHFBrb5LycNrSI6g.png"/></div><figcaption class="imageCaption">Across files, all variable that start with $ or _ will probably be in the red/orange spectrum.</figcaption></figure>

<p name="cb41" id="cb41" class="graf--p">Not sure if anyone has done work on this idea before, but I’m curious what it would be like to live with this implemented in a code editor. It might not scale to extremely large and/or complex files as is. But if you want to help, feel free to start with my code (or, even better, implement it in a smarter way!).</p>

      Bonjour/Hi!
      Je suis <a href="/david/" title="Profil public">David&nbsp;Larlet</a>, je vis actuellement à Montréal et j’alimente cet espace depuis 15 ans. <br>
      Si tu as apprécié cette lecture, n’hésite pas à poursuivre ton exploration. Par exemple via les <a href="/david/blog/" title="Expériences bienveillantes">réflexions bimestrielles</a>, la <a href="/david/stream/2019/" title="Pensées (dés)articulées">veille hebdomadaire</a> ou en t’abonnant au <a href="/david/log/" title="S’abonner aux publications via RSS">flux RSS</a> (<a href="/david/blog/2019/flux-rss/" title="Tiens c’est quoi un flux RSS ?">so 2005</a>).
    </p>
    <p>
      Je m’intéresse à la place que je peux avoir dans ce monde. En tant qu’humain, en tant que membre d’une famille et en tant qu’associé d’une coopérative. De temps en temps, je fais aussi des <a href="https://github.com/davidbgk" title="Principalement sur Github mais aussi ailleurs">trucs techniques</a>. Et encore plus rarement, <a href="/david/talks/" title="En ce moment je laisse plutôt la place aux autres">j’en parle</a>.
