|
<p>It’s been a while I didn’t packaged something new. I recently remembered an old
|
|
package of mine that needed some attention :
|
|
<a href="https://gitlab.com/almet/debts">debts</a>. It’s now time to package it, so I
|
|
discovered <a href="https://hatch.pypa.io/">hatch</a></p>
|
|
<p>hatch new —init</p>
|
|
<p>This does the heavy-lifting for you, actually porting the <code>setup.py</code> files to the
|
|
new way of packaging with python (with a <code>pyproject.toml</code> file)</p>
|
|
<p>Then <code>hatch shell</code> will create a development environment, install dependencies,
|
|
check the <code>pyproject.toml</code> file in one command, and give you a shell to test
|
|
whatever you need to test.</p>
|
|
<h2 id="isolating-system-packages">Isolating system packages</h2>
|
|
<p>I discovered that <a href="https://github.com/pypa/pipx">pipx</a> is a convenient way to
|
|
install user-facing applications on my system. I use multiple virtual
|
|
environments for my different projects, but not for the install that are used system-wide.</p>
|
|
<p>pipx seems to solve this, and avoid using <code>sudo pip install x</code>.</p>
|
|
<h2 id="manipulating-env-variables-with-zsh">Manipulating env variables with Zsh</h2>
|
|
<p>I use <a href="https://www.zsh.org/">Zsh</a> as my main shell for years, and I just
|
|
discovered that it’s possible to manipulate environment variables in an easy way.</p>
|
|
<p>If you’re like me, you never remember how to add something to your path. You
|
|
can actually use <code>+=</code>, like this:</p>
|
|
<div class="highlight"><pre><span></span><code><span class="nv">path</span><span class="o">+=(</span><span class="s1">'/Users/alexis/.local/bin'</span><span class="o">)</span>
|
|
<span class="nb">export</span><span class="w"> </span>PATH
|
|
</code></pre></div>
