<!-- SC_OFF --><div class="md"><p>How&#39;dy there!</p> <p>So my question is simple how can I prettify my pacman output.

<h2 id="an-external-brain">An External Brain</h2>
<p>I have a terrible memory…</p>
<p>And like most folks dealing w/ software architecture, I have to deal w/ a humongous amount of information.</p>
<p>So I take notes. Lots of them.</p>
<p>In fact I’ve extended this practice to every subjects I work on / study, with extensive cross-referencing.</p>
<p>The trick is not to remember stuff but to find it back quickly.</p>
<p>My current setup<sup id="fnref:1"><a class="footnote" href="https://www.eigenbahn.com/atom.emacs.xml#fn:1" rel="footnote">1</a></sup> is pretty straightforward: I use <a href="https://orgmode.org/">Org mode</a> inside <a href="https://www.eigenbahn.com/tag/emacs/">Emacs</a>. To quickly search a piece of information I use <a href="https://github.com/jrblevin/deft">deft</a> or sometimes <a href="https://github.com/Wilfred/deadgrep">deadgrep</a>.</p>
<p>The combination of these tools + my collection of notes act like an <strong>external brain</strong>.</p>
<h2 id="digital-gardening--zettlekasten">Digital Gardening &amp; Zettlekasten</h2>
<p>My notes are organized in a very specific way.</p>
<p>I organize them hierarchically under subfolders.</p>
<p>I like mid-sized files, only splitting them when they attain a critical mass in term of size or complexity.</p>
<p>This practice of building and maintaining a <strong>personal wiki</strong>, as old as the world itself, is now getting qualified of <a href="https://maggieappleton.com/garden-history"><em>digital gardening</em></a><sup id="fnref:2"><a class="footnote" href="https://www.eigenbahn.com/atom.emacs.xml#fn:2" rel="footnote">2</a></sup>. Indeed, you just don’t add content but have to regularly reorganize it, like you would clear a patch of soil.</p>
<p>I also stumbled upon the <a href="https://zettelkasten.de/introduction/"><em>Zettelkasten Method</em></a> and liked its idea of bidirectional links<sup id="fnref:3"><a class="footnote" href="https://www.eigenbahn.com/atom.emacs.xml#fn:3" rel="footnote">3</a></sup> but quickly rejected one aspect of its philosophy: creating many many small files, one for capturing each incoming thought.</p>
<p>Indeed, bidirectional links allow for a very fluid way to structure information (akin to what you may find in a graph database).</p>
<p>Still, I like to impose some structure, a taxonomy loosely based on how I mentally represent things. Having to deal with a gazillion files would not imped finding information back, but would discourage me from regularly <em>gardening</em> my notes.</p>
<p>So while I adhered to the <em>digital gardening</em> philosophy, I rejected (my understanding of) <em>Zettelkasten</em>.</p>
<h2 id="org-roam">Org-Roam</h2>
<p>I discovered <a href="https://github.com/org-roam/org-roam">Org-Roam</a> through its accompanying visualization tool: <a href="https://github.com/org-roam/org-roam-ui">Org-Roam-UI</a>.</p>
<p>It’s an extension to Org to provide it a similar feature set to <a href="https://roamresearch.com/">Roam</a>, the most famous <em>Zettlekasten</em> software.</p>
<p>Even if I didn’t buy to the <em>Zettlekasten</em> philosophy, the ability to graph all the notes relationships dynamically was tempting.</p>
<p>I took a quick look around and realized that the implementation isn’t too intrusive:</p>
<ul>
<li>relies on the native <code class="language-plaintext highlighter-rouge">org-id</code> feature</li>
<li>uses a local SQLite DB, but it’s only a cache that is easy to prune and re-create<sup id="fnref:4"><a class="footnote" href="https://www.eigenbahn.com/atom.emacs.xml#fn:4" rel="footnote">4</a></sup></li>
</ul>
<p>Furthermore, in its latest iteration it supports:</p>
<ul>
<li>recursive parsing of the notes directory</li>
<li>having note titles different from file names</li>
</ul>
<p>So I didn’t see any reason not to try it.</p>
<h2 id="indexing-an-existing-notes">Indexing an Existing Notes</h2>
<p>Things worked smoothly, but I was struggling to find a command to register existing notes in Org-Roam’s DB.</p>
<p>Calling <code class="language-plaintext highlighter-rouge">org-id-get-create</code> would allow generating an org id for current file / outline. But that wasn’t sufficient to make it appear.</p>
<p>Indeed, I also had to register it in the <code class="language-plaintext highlighter-rouge">org-id-locations-file</code> by passing the current file path to <code class="language-plaintext highlighter-rouge">org-id-update-id-locations</code>.</p>
<p>Finally, I needed to call <code class="language-plaintext highlighter-rouge">org-roam-db-update-file</code> for Org-Roam to update its DB entry for the current file.</p>
<p>This gives:</p>
<div class="language-elisp highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="p">(</span><span class="nb">defun</span> <span class="nv">prf/org-roam/add-index-current</span> <span class="p">()</span>
<span class="s">"Add index to file of currently visited buffer, if applicable."</span>
<span class="p">(</span><span class="nv">interactive</span><span class="p">)</span>
<span class="p">(</span><span class="nb">unless</span> <span class="p">(</span><span class="nb">and</span> <span class="p">(</span><span class="nv">buffer-file-name</span><span class="p">)</span>
<span class="p">(</span><span class="nv">file-exists-p</span> <span class="p">(</span><span class="nv">buffer-file-name</span><span class="p">)))</span>
<span class="p">(</span><span class="nv">user-error</span> <span class="s">"Current buffer is not visiting a file that exists on disk."</span><span class="p">))</span>
<span class="p">(</span><span class="nb">unless</span> <span class="p">(</span><span class="nv">prf/org/file-path-indexable-p</span> <span class="p">(</span><span class="nv">buffer-file-name</span><span class="p">))</span>
<span class="p">(</span><span class="nv">user-error</span> <span class="s">"Current buffer is not visiting an indexable file."</span><span class="p">))</span>
<span class="p">(</span><span class="nb">unless</span> <span class="p">(</span><span class="nv">org-id-get</span><span class="p">)</span>
<span class="p">(</span><span class="nv">org-id-get-create</span><span class="p">)</span>
<span class="p">(</span><span class="nv">call-interactively</span> <span class="nf">#'</span><span class="nv">save-buffer</span><span class="p">))</span>
<span class="p">(</span><span class="nv">org-id-update-id-locations</span> <span class="p">(</span><span class="nb">list</span> <span class="p">(</span><span class="nv">buffer-file-name</span><span class="p">)))</span>
<span class="p">(</span><span class="nv">org-roam-db-update-file</span><span class="p">))</span>
</code></pre></div></div>
<h2 id="forcing-index-of-all-files">Forcing Index of All Files</h2>
<p>Sometimes I like to massively rename / move / delete note files and Org-Roam doesn’t seem to be super happy about this.</p>
<p>Using the same logic as above, I came up w/ the following command:</p>
<div class="language-elisp highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="p">(</span><span class="nb">defun</span> <span class="nv">prf/org-roam/rescan</span> <span class="p">()</span>
<span class="s">"Force rescan of whole `prf/dir/notes'."</span>
<span class="p">(</span><span class="nv">interactive</span><span class="p">)</span>
<span class="p">(</span><span class="nv">prf/org/index-rescan-all</span><span class="p">)</span>
<span class="p">(</span><span class="nv">org-roam-db-sync</span><span class="p">))</span>
<span class="p">(</span><span class="nb">defun</span> <span class="nv">prf/org/index-rescan-all</span> <span class="p">()</span>
<span class="s">"Populate `org-id-locations' by rescaning recursively all files in `prf/dir/notes'."</span>
<span class="p">(</span><span class="nv">interactive</span><span class="p">)</span>
<span class="p">(</span><span class="k">let</span> <span class="p">((</span><span class="nv">buffs-snapshot</span> <span class="p">(</span><span class="nv">buffer-list</span><span class="p">)))</span>
<span class="p">(</span><span class="nv">org-id-update-id-locations</span>
<span class="p">(</span><span class="nv">f-files</span> <span class="nv">prf/dir/notes</span> <span class="nf">#'</span><span class="nv">prf/org/file-path-indexable-p</span> <span class="no">t</span><span class="p">))</span>
<span class="c1">;; NB: `org-id-update-id-locations' opens all matching files, we close them after processing</span>
<span class="p">(</span><span class="nb">mapc</span> <span class="nf">#'</span><span class="nv">kill-buffer</span>
<span class="p">(</span><span class="nv">-difference</span> <span class="p">(</span><span class="nv">buffer-list</span><span class="p">)</span> <span class="nv">buffs-snapshot</span><span class="p">))))</span>
</code></pre></div></div>
<h2 id="conclusion">Conclusion</h2>
<p>I’m pretty happy with this setup.</p>
<p>The Org-Roam-UI helps me visualize the current structure of my notes and has helped me discover patterns and anomalies I had no idea existed.</p>

<!-- SC_OFF --><div class="md"><p>Hello there. I&#39;ve always been interested in computer systems and GNU/Linux and I want to learn about it as much as I can to eventually even install and learn Gentoo and LFS and become an Advanced Linux Wizard. The only experience I have with Linux, though, is Ubuntu, which I used mainly when my PCs broke. I was about to use it as my main OS but I never did so once they replaced Unity with Gnome, which I never really liked that much. Gaming eventually made me go back to Windows, which I&#39;ve used since then.</p> <p>I have a few old PCs lying around that I want to revive, and this is a good opportunity to learn. I remember having lots of fun using the console in Ubuntu —something that&#39;s nearly absent in Windows— but I think it&#39;s time to hop to something more advanced, and I think that something like Debian or Suse or Fedora just won&#39;t do. What do you think? Would it be unwise and masochist to hop into Arch, or is it not that complicated assuming you put in enough time to figure things out and read? Thank you.</p> </div><!-- SC_ON --> &#32; submitted by &#32; <a href="https://www.reddit.com/user/Yumemiyou"> /u/Yumemiyou </a> <br/> <span><a href="https://www.reddit.com/r/archlinux/comments/qyfq0t/jumping_from_ubuntu_to_arch_as_a_beginner/">[link]</a></span> &#32; <span><a href="https://www.reddit.com/r/archlinux/comments/qyfq0t/jumping_from_ubuntu_to_arch_as_a_beginner/">[comments]</a></span>
