Snip Snap

<div class="post-text">
<p>I regularly switch between exactly two things while working, a
“current” and an “alternate” item; a lot of tools I use seem to support
this flow.</p>
<h4 id="git">git</h4>
<p>Pass <code>-</code> to <code>git-checkout</code> to switch to the
previously active branch:</p>
<div class="sourceCode" id="cb1"><pre
class="sourceCode bash"><code class="sourceCode bash"><span id="cb1-1"><a href="#cb1-1" aria-hidden="true" tabindex="-1"></a><span class="ex">$</span> git branch</span>
<span id="cb1-2"><a href="#cb1-2" aria-hidden="true" tabindex="-1"></a><span class="ex">*</span> foo</span>
<span id="cb1-3"><a href="#cb1-3" aria-hidden="true" tabindex="-1"></a> <span class="ex">bar</span></span>
<span id="cb1-4"><a href="#cb1-4" aria-hidden="true" tabindex="-1"></a></span>
<span id="cb1-5"><a href="#cb1-5" aria-hidden="true" tabindex="-1"></a><span class="ex">$</span> git checkout bar</span>
<span id="cb1-6"><a href="#cb1-6" aria-hidden="true" tabindex="-1"></a><span class="ex">$</span> git branch</span>
<span id="cb1-7"><a href="#cb1-7" aria-hidden="true" tabindex="-1"></a> <span class="ex">foo</span></span>
<span id="cb1-8"><a href="#cb1-8" aria-hidden="true" tabindex="-1"></a><span class="ex">*</span> bar</span>
<span id="cb1-9"><a href="#cb1-9" aria-hidden="true" tabindex="-1"></a></span>
<span id="cb1-10"><a href="#cb1-10" aria-hidden="true" tabindex="-1"></a><span class="ex">$</span> git checkout <span class="at">-</span></span>
<span id="cb1-11"><a href="#cb1-11" aria-hidden="true" tabindex="-1"></a><span class="ex">$</span> git branch</span>
<span id="cb1-12"><a href="#cb1-12" aria-hidden="true" tabindex="-1"></a><span class="ex">*</span> foo</span>
<span id="cb1-13"><a href="#cb1-13" aria-hidden="true" tabindex="-1"></a> <span class="ex">bar</span></span></code></pre></div>
<h4 id="bash---cd">bash - cd</h4>
<p>This may not be exclusive to <code>bash</code>:</p>
<div class="sourceCode" id="cb2"><pre
class="sourceCode bash"><code class="sourceCode bash"><span id="cb2-1"><a href="#cb2-1" aria-hidden="true" tabindex="-1"></a><span class="ex">~/foo</span> $ cd ~/bar</span>
<span id="cb2-2"><a href="#cb2-2" aria-hidden="true" tabindex="-1"></a><span class="ex">~/bar</span> $ cd <span class="at">-</span></span>
<span id="cb2-3"><a href="#cb2-3" aria-hidden="true" tabindex="-1"></a><span class="ex">~/foo</span> $</span></code></pre></div>
<p>This is especially handy in combination with my <a
href="../curing_a_case_of_git-UX/">git-worktree flow</a>:</p>
<div class="sourceCode" id="cb3"><pre
class="sourceCode bash"><code class="sourceCode bash"><span id="cb3-1"><a href="#cb3-1" aria-hidden="true" tabindex="-1"></a><span class="ex">~/main-branch</span> $ gwj feature</span>
<span id="cb3-2"><a href="#cb3-2" aria-hidden="true" tabindex="-1"></a><span class="ex">~/feat-branch</span> $ cd <span class="at">-</span></span>
<span id="cb3-3"><a href="#cb3-3" aria-hidden="true" tabindex="-1"></a><span class="ex">~/main-branch</span> $</span></code></pre></div>
<h4 id="bash---jobs">bash - jobs</h4>
<p>I often suspend multiple <code>vim</code> sessions with
<code>Ctrl-Z</code>:</p>
<div class="sourceCode" id="cb4"><pre
class="sourceCode bash"><code class="sourceCode bash"><span id="cb4-1"><a href="#cb4-1" aria-hidden="true" tabindex="-1"></a><span class="ex">$</span> jobs</span>
<span id="cb4-2"><a href="#cb4-2" aria-hidden="true" tabindex="-1"></a><span class="ex">[1]+</span> Stopped vim transpiler/src/transform.rs</span>
<span id="cb4-3"><a href="#cb4-3" aria-hidden="true" tabindex="-1"></a><span class="ex">[2]-</span> Stopped git commit <span class="at">--verbose</span></span></code></pre></div>
<p>In the above example: I suspended <code>vim</code> when working on
<code>transform.rs</code>, and then began working on a commit by running
<code>git commit</code> without a message flag (lets you craft a message
in <code>$EDITOR</code>). To bring the current job to the foreground,
you can use <code>fg</code>:</p>
<div class="sourceCode" id="cb5"><pre
class="sourceCode bash"><code class="sourceCode bash"><span id="cb5-1"><a href="#cb5-1" aria-hidden="true" tabindex="-1"></a><span class="ex">$</span> fg</span></code></pre></div>
<p>With a job identifier:</p>
<div class="sourceCode" id="cb6"><pre
class="sourceCode bash"><code class="sourceCode bash"><span id="cb6-1"><a href="#cb6-1" aria-hidden="true" tabindex="-1"></a><span class="ex">$</span> fg %2 <span class="co"># resumes interactive git commit</span></span></code></pre></div>
<p>Or switch to “last” job, or the second-most-recently-resumed job:</p>
<div class="sourceCode" id="cb7"><pre
class="sourceCode bash"><code class="sourceCode bash"><span id="cb7-1"><a href="#cb7-1" aria-hidden="true" tabindex="-1"></a><span class="ex">$</span> fg %-</span>
<span id="cb7-2"><a href="#cb7-2" aria-hidden="true" tabindex="-1"></a><span class="ex">$</span> %- <span class="co"># shorthand</span></span></code></pre></div>
<h4 id="vim">vim</h4>
<p>Switch to the last active buffer with <code>Ctrl+^</code>. In
command-mode, <code>#</code> refers to the last active buffer, you can
use this as an argument to a few commands:</p>
<pre class="vimscript"><code>:b# " switch to alternate buffer (same as Ctrl+^)
:vsp# " create a vertical split with the alternate buffer
:read# " read contents of alternate buffer into current buffer
:!wc # " pass file name of alternate buffer to the command `wc`</code></pre>
<p>See <code>:help c_#</code> for more.</p>
<h4 id="tmux">tmux</h4>
<p>Switch to the last active tmux session with
<code><prefix>+shift+L</code>.</p>
<h4 id="qutebrowser">qutebrowser</h4>
<p>Switch to the last active tab with <code>g$</code>.</p>
