Now we have to handle the required set of i3 commands. It is worth noting here that I'm not trying to implement a general mechanism to apply i3 commands to Emacs, rather I'm implementing a small subset that I use in my i3 configuration and that maps reasonably to the Emacs concepts.

<description>Intro One advantage of EXWM for an Emacs user is that EXWM gives one set of keybindings to manage both Emacs windows and X windows. In every other WM, like my preferred i3wm, two orthogonal keymaps seem to be necessary. But, as both programs are quite customizable, I want to see whether I can replicate at least some part of the EXWM goodness in i3.

But why not just use EXWM?</description>

<p>One advantage of EXWM for an Emacs user is that EXWM gives one set of keybindings to manage both Emacs windows and X windows. In every other WM, like my preferred <a href="https://i3wm.org">i3wm</a>, two orthogonal keymaps seem to be necessary. But, as both programs are quite customizable, I want to see whether I can replicate at least some part of the EXWM goodness in i3.</p>
|
||||
<p>But why not just use EXWM? One key reason is that to my taste (and perhaps on my hardware) EXWM didn’t feel snappy enough. Also, I really like i3’s tree-based layout structure; I feel like it fits my workflow much better than anything else I tried, including the master/stack paradigm of <a href="https://xmonad.org/">XMonad</a>, for instance.</p>
|
||||
<p>One common point of criticism of i3 is that it is not extensible enough, especially compared to WMs that are configured in an actual programing language, like the mentioned XMonad, <a href="http://www.qtile.org/">Qtile</a>, <a href="https://awesomewm.org/">Awesome</a>, etc. But I think i3’s extensibility is underappreciated, although the contents of this article may lie closer to the limits of how far one can go there.</p>
|
||||
<p>Here is a small demo of how it currently works:</p>

<h2 id="emacs-integration">Emacs integration</h2>
|
||||
<p>What I’m trying to do is actually quite simple, so I’m somewhat surprised I didn’t find anything similar on the Internet. But I didn’t look too hard.</p>
|
||||
<p>The basic idea is to launch a normal i3 command with <code>i3-msg</code> in case the current window is not Emacs, otherwise pass that command to Emacs with <code>emacsclient</code>. In Emacs, execute the command if possible, otherwise pass the command back to i3.</p>
|
||||
<p>This may seem like a lot of overhead, but I didn’t feel it even in the worst case (i3 -> Emacs -> i3), so at least in that regard, the interaction feels seamless. The only concern is that this command flow is vulnerable to Emacs getting stuck, but it is still much less of a problem than with EXWM.</p>
|
||||
<p>One interesting observation here is that Emacs windows and X windows are sort of one-level entities, so I can talk just about “windows”.</p>
|
||||
<p>At any rate, we need a script to do the i3 -> Emacs part:</p>
|
||||

</code></pre></div><p>My <a href="https://sqrtminusone.xyz/configs/emacs/#custom-frame-title">Emacs frame title is set</a> to <code>emacs[:<projectile-project-name>]@<hostname></code>, hence the regex. The script is saved to an executable called <code>emacs-i3-integration</code>.</p>
|
||||
<p>For this to work, we need to make sure that Emacs starts a server, so here is an expression to do just that:</p>
|
||||
<div class="highlight"><pre tabindex="0" style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-emacs-lisp" data-lang="emacs-lisp">(add-hook <span style="color:#e6db74">'after-init-hook</span> <span style="color:#a6e22e">#'</span>server-start)
|
||||
</code></pre></div><p>The function <code>my/emacs-i3-integration</code>, which is an entrypoint for the i3 integration, will be defined a bit later.</p>
|
||||
<p>And here is a simple macro to do the Emacs -> i3 part:</p>
|
||||
<div class="highlight"><pre tabindex="0" style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-emacs-lisp" data-lang="emacs-lisp">(defmacro i3-msg (<span style="color:#66d9ef">&rest</span> args)

|
||||
</code></pre></div><h2 id="handling-i3-commands">Handling i3 commands</h2>
|
||||
<p>Now we have to handle the required set of i3 commands. It is worth noting here that I’m not trying to implement a general mechanism to apply i3 commands to Emacs, rather I’m implementing a small subset that I use in my i3 configuration and that maps reasonably to the Emacs concepts.</p>
|
||||
<p>Also, I use <a href="https://github.com/emacs-evil/evil">evil-mode</a> and generally configure the software to have vim-style bindings where possible. So if you don’t use evil-mode you’d have to detangle the given functions from evil, but then, I guess, you do not use super+hjkl to manage windows either.</p>
|
||||
<h3 id="focus"><code>focus</code></h3>
|
||||
<p>First, for the <code>focus</code> command I want to move to an Emacs window in the given direction if there is one, otherwise move to an X window in the same direction. Fortunately, i3 and <code>windmove</code> have the same names for directions, so the function is rather straightforward.</p>
|
||||
<p>One caveat here is that the minibuffer is always the bottom-most Emacs window, so it is necessary to check for that as well.</p>

|
||||
bindsym $mod+Up exec emacs-i3-integration focus up
|
||||
bindsym $mod+Right exec emacs-i3-integration focus right
|
||||
</code></pre></div><p>The Emacs function has to be called like that:</p>
|
||||
<div class="highlight"><pre tabindex="0" style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-emacs-lisp" data-lang="emacs-lisp">(my/emacs-i3-windmove <span style="color:#e6db74">'right</span>)
|
||||
</code></pre></div><h3 id="move"><code>move</code></h3>
|
||||
<p>For the <code>move</code> command I want the following behavior:</p>
|
||||
<ul>
|
||||
<li>if there is space in the required direction, move the Emacs window there;</li>
|
||||
<li>if there is no space in the required direction, but space in the orthogonal directions, move the Emacs window so that there is no more space in the orthogonal directions;</li>
|
||||
<li>otherwise, move an X window (which has to be an Emacs frame).</li>
|
||||
</ul>
|
||||
<p>For the first part, <code>window-swap-states</code> with <code>windmove-find-other-window</code> do well enough.</p>
|
||||
<p><code>evil-move-window</code> works well for the second part. By itself it doesn’t behave quite like i3, for instance, <code>(evil-move-window 'right)</code> in a three-column split would move the window from the far left side to the far right side (bypassing center). Hence the combination as described here.</p>
|
||||
<p>So here is a simple predicate which checks whether there is space in the given direction.</p>

||||

</code></pre></div><p>Next, Emacs has a built-in function called <code>balance-windows</code>, but i3 doesn’t. Fortunately, there is a Python package called <a href="https://github.com/atreyasha/i3-balance-workspace">i3-balance-workspace</a>, which performs a similar operation with i3’s IPC. If you use Guix as I do, I’ve written a <a href="https://github.com/SqrtMinusOne/channel-q/blob/master/i3-balance-workspace.scm">package definition</a>.</p>
|
||||
<p>So here is a small wrapper which calls <code>i3_balance_workspace</code> and <code>M-x balance-windows</code> if the current window is Emacs.</p>

|
||||
<p>As I use i3’s tabbed layout quite extensively, occasionally I want to switch out of the Emacs tab with one button, and that’s where my integration may interfere.</p>
|
||||
<p>As a workaround, I found a small Rust program called <a href="https://github.com/nikola-kocic/i3-switch-tabs">i3-switch-tabs</a>, which also communicates with i3 via its IPC to switch the top-level tab. I’ve written a <a href="https://github.com/SqrtMinusOne/channel-q/blob/master/i3-switch-tabs.scm">Guix package definition</a> for that as well.</p>
|
||||
<div class="highlight"><pre tabindex="0" style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-bash" data-lang="bash">bindsym $mod+period exec i3-switch-tabs right
|
||||
bindsym $mod+comma exec i3-switch-tabs left
|
||||
</code></pre></div><h2 id="conclusion">Conclusion</h2>
|
||||
<p>So, how does all of that feel? Actually, I got used to that setup pretty quickly. Using <code><s-Q></code> to quit windows and the <code><s-r></code> submode to resize them is particularly nice. I’ve seen people making hydras in Emacs to do the latter.</p>
|
||||
<p>All of that would probably be easier to do in a WM which is configured in a programming language rather than in a self-cooked DSL, so I may try to replicate that somewhere else in an unknown time in the future. Meanwhile, it’s pretty good.</p>

<description>Intro One advantage of EXWM for an Emacs user is that EXWM gives one set of keybindings to manage both Emacs windows and X windows. In every other WM, like my preferred i3wm, two orthogonal keymaps seem to be necessary. But, as both programs are quite customizable, I want to see whether I can replicate at least some part of the EXWM goodness in i3.
|
||||
But why not just use EXWM?</description>
