I've been using <a href="https://github.com/tkf/emacs-jedi">Emacs Jedi</a> for almost as long as I've been writing Python, and it has been pretty helpful at completing away long names.</p> +<p>However, Jedi uses <code>python</code> by default, which means <code>python2</code> on most of our systems at this point. Occasionally I'm writing Python 3 specific code but Jedi completes to Python 2 or refuses to complete; for the record, I enjoy writing and debugging Python 3.3+ much better than 2.7 (I realized this after trying to create a code base that is backward compatible with 2.7, which means reinventing the wheel or introducing annoying branches from time to time). So naturally I'm looking into using Python 3 in Jedi.</p> +<p>The <a href="https://tkf.github.io/emacs-jedi/latest/#how-to-use-python-3-or-any-other-specific-version-of-python">official docs</a> has been confusing and unhelpful at least for me, since it insists on setting up the virtualenv from within Emacs, and it failed for me. Why can't I set up the virtualenv myself? Turns out I can, and it's incredibly simple. The commands below assume that you have installed Jedi and friends (well, dependencies) using <code>package.el</code>.</p> +<div class="sourceCode"><pre class="sourceCode bash"><code class="sourceCode bash"><span class="fu">mkdir</span> -p ~/.emacs.d/.python-environments +<span class="ex">virtualenv</span> -p /usr/local/bin/python3 ~/.emacs.d/.python-environments/jedi # or whatever your python3 path is +<span class="co"># If you feel like installing the server with 'M-x jedi:install-server', also do the following</span> +<span class="ex">~/.emacs.d/.python-environments/jedi/bin/pip</span> install --upgrade ~/.emacs.d/elpa/jedi-20150109.2230/ # you might need to change the version number</code></pre></div> +<p>And that's it. Put the following in your <code>~/.emacs</code>:</p> +<div class="sourceCode"><pre class="sourceCode commonlisp"><code class="sourceCode commonlisp">(add-hook 'python-mode-hook 'jedi:setup) +(<span class="kw">setq</span> jedi:complete-on-dot <span class="kw">t</span>) +(<span class="kw">setq</span> jedi:environment-root <span class="st">"jedi"</span>)</code></pre></div> +<p>where the first two lines should be there whether you want to use Python 3 or not — so only the third line is new, and its meaning is obvious.</p> +<p>At last, start Emacs and do <code>M-x jedi:install-server</code> if you haven't run the <code>pip</code> command above yet. Restart Emacs (if necessary). That's it. Enjoy your Jedi with Python 3. (Type <code>import conf</code>, for instance, to be convinced that you're really autocompleting Python 3).</p> +</article> +<hr class="content-separator"/> +<footer class="footer"> +<span class="rfooter"> +<a class="rss-icon" href="/rss.xml" target="_blank" title="RSS feed"><!--RSS feed icon--></a><a class="atom-icon" href="/atom.xml" target="_blank" title="Atom feed"><!--Atom feed icon--></a><a class="cc-icon" href="https://creativecommons.org/licenses/by/4.0/" target="_blank" title="Released under the Creative Commons Attribution 4.0 International license."><!--CC icon--></a> +<a href="https://github.com/zmwangx" target="_blank">Zhiming Wang</a> +</span> +</footer> +</body> +</html> |
