Emacs Stability

A while ago I packaged up my emacs configuration for the world to see/use and I'm pretty proud of this thing: it works well out of the box, it's super minimal and speedy, and has all of the features. I don't think it's the right solution for everyone, but I think there are a case of users for whom this configuration makes sense. I've definitely also benefited a lot for thinking about this "configuration" as a software project at least in terms of keeping things organized and polished and reasonably well tested. It's a good exercise.

Historically, I've used my emacs configuration ans as a sort of "fun side project" and while I tried to avoid spending too much time tweaking various things, it did feel like the kind of thing that was valuable (given how much time I spend in a text editor,) without being too distracting. Particularly, early in the pandemic, or during periods over the summer when I was between jobs.

Then, I put the configuration in a public repo, and I basically haven't made any meaningful changes since then. One part of this is clearly that I put a lot of time into polishing things in the initial push to get it released, and there haven't been many bugs that have inspried any kind of major development effort. Another part is that, the way I use an editor isn't really changing. I'm writing code and English and using a couple of applications (e.g. email and org-mode) within emacs, but I'm not really (often) adding new or different kinds of work, and while this isn't exacting from a blogging perspective* it is exciting from a "things just work perspective."

I have refered to myself as a degenerate emacs user. I've sometimes said unrepentant, but I think it's basically the same. I've also realized that, given that I've basically been using emacs the same way since 2008 or so, I'm kind of an old timer, even if it doesn't much feel like that, and there are lots of folks with longer histories.

I think I used care more about what tools other people used to edit text, even a couple of years ago, I thought that having good initial configuration and better out of the box experiences for emacs would lead to more people using emacs, which would be cool because they'd get to use a cool piece of software and we'd get more emacs users.

Increasingly, however, while I think emacs is great and people should use it, I'm less concerned: people should use what they want, and I think there will always be a enough people here and there who want to use emacs and that's good enough for me. I think having good out of the box experiences are important, but it's not a one-size fits all kind of situation. I also think that VS Code is pretty great software, and I like a lot of the implications for remote editing, even if I'm not particularly interested in it for myself.

Enjoy the repo, and let me know if there's anything terrible about it. I've been getting back into blogging recently, and have started tweaking a few things about the ways I use computers/emacs, mostly in terms of exploring tmux (hah!) and also considering avoiding GUI emacs entirely. Stay tuned if you're interested!

The Emacs Daemon GTK Bug, A Parable

There's this relatively minor Emacs bug that I've been aware of for a long time, years. The basic drift is that on Linux systems, when running with GTK/Emacs as a daemon, and the X11 session terminates for any reason the Emacs daemon terminates. Emacs daemons are great: you start Emacs once, and it keeps running independently of what ever windows you have open. You can leave files open in Emacs buffers and not have move between different projects with minimal context switching costs.

First of all, emacs's daemon mode is weird. I can't think of another application that starts as a daemon (in the conventional UNIX double-forking manner,) and then a client process runs and spawns GUI (potentially) windows. If there are other applications that work this way, there aren't many.

Nevertheless, being able to restart the window manager without loosing the current state of your Emacs session is one of the chief reasons to run Emacs in daemon mode, so this bug has always been a bit irksome. Also since it's real, and for sure a thing, why has it taken so long to address? Lets dig a little bit deeper.

There are two GNOME bugs related to this:

What's happening isn't interesting or complicated: Emacs calls an API, which behaves differently than Emacs expects and needs, but not (particularly) differently than GNOME expects or needs. Which means GNOME has little incentive to fix the bug--if they even could without breaking other users of this API.

Emacs can't fix the problem on their own, without writing a big hack around GNOME components, which wouldn't be particularly desirable or viable, and because this works fine with the other toolkit (and is only possible in some situations,) it doesn't feel like an Emacs bug.

We have something of a stalemate. Both party thinks the other is at fault. No one is particularly incentivized to fix the problem from their own code, and there is a work around, [1] albeit a kind of gnarly one.

This kind of issue feels, if not common, incredibly easy for a project--even one like emacs--to stumble into and quite easy to just never resolve. This kind of thing happens, in some form, very often and boundaries between libraries make it even more likely.

On the positive side, It does seem like there's recent progress on the issue, so it probably won't be another 10 years before it gets fixed, but who knows.

[1]To avoid this problem either: don't use GUI emacs windows and just use the terminal (fairly common, and more tractable as terminal emulators have improved a bunch in the past few years,) or use the Lucid GUI toolkit, which doesn't depend on GTK at all. The lucid build is ugly (as the widgets don't interact with GTK settings,) but its light weight and doesn't suffer the '

The Org Mode Product

As a degenerate emacs user, as it were, I have of course used org-mode a lot, and indeed it's probably the mode I end up doing a huge amount of my editing in, because it's great with text and I end up writing a lot of text. I'm not, really, an org mode user in the sense that it's not the system or tool that I use to stay organized, and I haven't really done much development of my own tooling or process around using orgmode to handle document production, and honestly, most of the time I use reStructuredText as my preferred lightweight markup language.

I was thinking, though, as I was pondering ox-leanpub, what even is org-mode trying to do and what the hell would a product manager do, if faced with org-mode.

In some ways, I think it sucks the air out of the fun of hacking on things like emacs to bring all of the "professionalization of making software" to things like org-mode, and please trust that this meant with a lot of affection for org-mode: this is meant as a thought experiment.

Org has a lot going on:

  • it provides a set of compelling tools for interacting with hierarchical human-language documents.
  • it's a document markup and structure system,
  • the table editing features are, given the ability to write formula in lisp, basically a spreadsheet.
  • it's a literate programming environment, (babel)
  • it's a document preparation system, (ox)
  • it's a task manager, (agenda)
  • it's a time tracking system,
  • it even has pretty extensive calendar management tools.

Perhaps the thing that's most exciting about org-mode is that it provides functionality for all of these kinds of tasks in a single product so you don't have to bounce between lots of different tools to do all of these things.

It's got most of the "office" suite covered, and I think (particularly for new people, but also for people like me,) it's not clear why I would want my task system, my notes system, and my document preparation system to all have their data intermingled in the same set of files. The feeling is a bit unfocused.

The reason for this, historically makes sense: org-mode grew out of technically minded academics who were mostly using it as a way of preparing papers, and who end up being responsible for a lot of structuring their own time/work, but who do most of their work alone. With this kind of user story in mind, the gestalt of org-mode really comes together as a product, but otherwise it's definitely a bit all over the place.

I don't think this is bad, and particularly given its history, it's easy to understand why things are the way they are, but I think that it is useful to take a step back and think about the workflow that org supports and inspires, while also not forgetting the kinds of workflows that it precludes, and the ways that org, itself, can create a lot of conceptual overhead.

There are also some gaps, in org, as a product, which I think grow out of this history, and I think there are

They are, to my mind:

  • importing data, and bidirectional sync. These are really hard problems, and there've been some decent projects over the years to help get data into org, I think org-trello is the best example I can think about, but it can be a little dodgy, and the "import story" pales in comparison to the export story. It would be great if:
    • you could use the org interface to interact with and manipulate data that isn't actually in org-files, or at least where the system-of-record for the data isn't org. Google docs? Files in other formats?
  • collaborating with other people. Org-mode files tend to cope really poorly with multiple people editing them at the same time (asynchronously as with git,) and also in cases where not-everyone uses org-mode. One of the side effects of having the implementation of org-features so deeply tied to the structure of text in the org-format, it becomes hard to interact with org-data outside of emacs (again, you can understand why this happens, and it's indeed very lispy,), which means you have to use emacs and use org if you want to collaborate on projects that use org.
    • this might look like some kind of different diff-drivers for git, in addition to some other more novel tools.
    • bi-directional sync might also help with this issue.
  • beyond the agenda, building a story for content that spans multiple-file. Because the files are hierarchical, and org provides a great deal of taxonomic indexing features, you really never need more than one org-file forever, but it's also kind of wild to just keep everything in one file, so you end up with lots of org-files, and while the agenda provides a way to filter out the task and calendar data, it's sort of unclear how to mange multi-file systems for some of the other projects. It's also the case, that because you can inject some configuration at the file level, it can be easy to get stuck.
  • tools for interacting with org content without (interactive or apparent) emacs. While I love emacs as much as the next nerd, I tend to think that having a dependency on emacs is hard to stomach, particularly for collaborative efforts, (though with docker and the increasing size of various runtimes, this may be less relevant.) If it were trivially easy to write build processes that extracted or ran babel programs without needing to be running from within emacs? What if there were an org-export CLI tool?

Editor Themes

It's not real secret that I'm red-green colorblind. It's not really a major life obstacle: I've got a wardrobe of clothes in colors that I can easily tell apart, I have developed a number of heuristics for guessing colors that are right enough, and mostly it just creates funny stories where I get a confused look if I try to describe something that might be purple, or have to convince a coworker into reading a graph for me.

One challenge historically, however, has been various kinds of text editing color themes: so often they end up having some kind of low contrast situation that's hard to read, or two different aspects of code that should be highlighted differently but aren't. I've tried lots of themes out, and I would always end up just going back and using default emacs themes, which might not have been great, but I always found it useable.

Until Protesilaos Stavrou's Modus Themes, that is.

These are super compelling and I never really knew how good an editor could look until I started using it. Like is this what it's really like for the rest of you all the time? Things are clear: I never get confused between type names and function names any more. There are rarely situations where I feel like the highlighting color and text color are the same, which used to happen all the time.

The real win, I think, is that Modus' makes dark themes accessible to me, in a way that they never were before. For the most part "dark themes" which have been so popular recently, are just impossible to see clearly (for me), I also find that it's less taxing to spend time in front of screens when darker backgrounds, so being able to spend most of my time doing work in an environment that's easy to read. I tend to keep to light backgrounds when using a laptop and dark backgrounds otherwise.

The second piece is that, I think I've caved in and decided to increase the size of the font, by default in my text editor, at least when I'm using my desktop/external monitor. I think my vision is as good as it's been, though I should probably get that checked out post-pandemic. I think there's a balance between "small fonts let you see more of the file you're working on," and "larger fonts let you focus on the area that you're editing." When I'm writing English, the focus is great, and when writing software I tend to want more context. There's a balance also in wanting to keep an entire line length viable at once, and an ideal words-per-line limit for text that's useful for making things easier to read. So there's some tuning there, depending on what your workload looks like.

I guess if there is any lesson in this it's that: Comfort matters, and you shouldn't push yourself into uncomfortable display situations if you can.

Open Source Emacs Configuration Improvements

In retrospect I'm not totally sure why I released my emacs configuration to the world. I find tweaking Emacs Lisp to be soothing, and in 2020 these kinds of projects are particularly welcome. I've always thought about making it public: I feel like I get a lot out of Emacs, and I'm super aware that it's very hard for people who haven't been using Emacs forever to get a comparable experience. [1]

I also really had no idea of what to expect, and while it's still really recent, I've noticed a few things which are worth remarking:

  • Making your code usable for other people really does make it easy for people to find bugs. While it's likely that there are bugs that people never noticed, I found a few things very quickly:

    • Someone reported higher than expected CPU use, and I discovered that there were a number of functions that ran regularly in timers, and I was able to quickly tune some knobs in order to reduce average CPU use by a lot. This is likely to be great both for the user in question, but also because it'll help battery life.
    • The config includes a git submodule (!) with the contents of all third-party packages, mostly to reduce friction for people getting started. Downloading all of the packages fresh from the archive would take a few minutes, and the git clone is just faster. I realized, when someone ran into some problems when running with emacs 28 (e.g. the development/mainline build,) that the byte-compilation formats were different, which made the emacs27 files not work on emacs28. I pushed a second branch.

    More than anything the experience of getting bug reports and feedback has been great. It both makes it possible to focus time because the impact of the work is really clear, and it also makes it clear to me that I've accumulated some actually decent Emacs Lisp skills, without really noticing it. [2]

  • I was inspired to make a few structural improvements.

    • For a long time, including after the initial release, I had a "settings" file, and a "local functions" file that held code that I'd written or coppied from one place or another, and I finally divided them all into packages named tychoish-<thing>.el which allowed me to put all or most of the configuration into use-package forms, which is more consistent and also helps startup time a bit, and makes the directory structure a bit easier.
    • I also cleaned up a bunch of local snippets that I'd been carrying around, which wasn't hurting anything but is a bit more clear in the present form.
  • I believe that I've hit the limit, with regards to startup speed. I'd really like to get a GUI emacs instance to start (with no buffers) in less than a second, but it doesn't seem super plausible. I got really close. At this point there are two factors that constrain:

    • Raw CPU speed. I have two computers, and the machine with the newer CPU is consistently 25% faster than the slow computer.
    • While the default configuration doesn't do this, my personal configuration sets a font (this is reasonable,) but seems that the time to do this is sometimes observable, and proportional to the number of fonts you have installed on the system. [3]
    • Dependencies during the early load. I was able to save about 10% time by moving a function between package to reduce the packages that startup code depended upon. There's just a limit to how much you can clean up here.

    Having said that, these things can drift pretty easily. I've added some helper macros with-timer and with-slow-op-timer that I can use to report the timing of operations during startup to make sure that things don't slow down.

    Interestingly, I've experimented with byte-compiling my local configuration and I haven't really noticed much of a speedup at this scale, so for ease I've been leaving my own lisp directory unbytecompiled.

  • With everything in order, there's not much to edit! I guess I'll have other things to work on, but I have made a few improvements, generally:

    • Using the alert package for desktop notification, which allowed me to delete a legacy package I've been using. Deleting code is awesome.
    • I finally figured out how to really take advantage of projectile, which is now configured correctly, and has been a lot of help in my day-to-day work.
    • I've started using ERC more, and only really using my irssi (in screen) session as a fallback. My IRC/IM setup is a bit beyond the scope of this post but ERC has been a bit fussy to use on machines with intermittent connections, but I think I've been able to tweak that pretty well and have an experience that's quite good.

It's been interesting! And I'm looking forward to continuing to do this!

[1]Sure, other editors also have long setup curves, but Emacs is particularly gnarly in this regard, and I think adoption by new programmers is definitely constrained by this fact.
[2]I never really thought of myself as someone who wrote Emacs Lisp: I've never really written a piece of software in Emacs, it's always been a function here or there, or modifying some snippet from somewhere. I don't know if I have a project or a goal that would involve writing more emacs software, but it's nice to recognize that I've accidentally acquired a skill.
[3]On Windows and macOS systems this may not matter, but you may have more fonts installed than you need. I certianly did. Be aware that webbrowsers often downlaod their own fonts separately from system fonts, so having fonts installed is really relevant to your GTK/QT/UI use and not actually to the place where you're likely doing most of your font interaction (e.g. the browser.)

Better Company

I've been using company mode, which is a great completion framework for years now, and in genreal, it's phenomenal. For a while, however, I've had the feeling that I'm not getting completion options at exactly the right frequency that I'd like. And a completion framework that's a bit sluggish or that won't offer completions that you'd expect is a drag. I dug in a bit, and got a much better, because of some poor configuration choices I'd made, and I thought I write up my configuration.

Backend Configuration

Company allows for configurable backends, which are just functions that provide completions, many of which are provided in the main company package, but also provided by many third (fourth?) party packages. These backends, then, are in a list which is stored in the company-backends, that company uses to try and find completions. When you get to a moment when you might want to complete things, emacs+company iterate through this list and build a list of expansions. This is pretty straight forward, at least in principle.

Now company is pretty good at making these backends fast, or trying, particularly when the backend might be irrelevant to whatever you're currently editing--except in some special cases--but it means that the order of things in the list matters sometimes. The convention for configuring company backends is to load the module that provides the backend and then push the new backend onto the list. This mostly works fine, but there are some backends that either aren't very fast or have the effect of blocking backends that come later (because they're theoretically applicable to all modes.) These backends to be careful of are: company-yasnippet, company-ispell, and company-dabbrev.

I've never really gotten company-ispell to work (you have to configure a wordlist,) and I've never been a dabbrev user, but I've definitely made the mistake to putting the snippet expansion near the front of the list rather than the end. I've been tweaking things recently, and have settled on the following value for company-backends:

(setq company-backends '(company-capf

The main caveat is that everything has to be loaded or have autoloads registered appropriately, particularly for things like jedi (python,) clang, and irony. The "capf" backend is the integration with emacs' default completion-at-point facility, and is the main mechanism by which lap-mode interacts with company, so it's good to keep that at the top.

Make it Fast

I think there's some fear that a completion framework like company could impact the perceived responsiveness of emacs as a whole, and as a result there are a couple of knobs for how to tweak things. Having said that, I've always run things more aggressively, because I like seeing possible completions fast, and I've never seen any real impact on apparent performance or battery utilization. use these settings:

(setq company-tooltip-limit 20)
(setq company-show-numbers t)
(setq company-idle-delay 0)
(setq company-echo-delay 0)

Configure Prompts

To be honest, I mostly like the default popup, but it's nice to be able to look at more completions and spill over to helm when needed. It's a sometimes thing, but it's quite nice:

(use-package helm-company
   :ensure t
   :after (helm company)
   :bind (("C-c C-;" . helm-company))
   :commands (helm-company)
   (define-key company-mode-map (kbd "C-;") 'helm-company)
   (define-key company-active-map (kbd "C-;") 'helm-company))

Full Configuration

Some of the following is duplicated above, but here's the full configuration that I run with:

(use-package company
  :ensure t

Towards Faster Emacs Start Times

While I mostly run emacs as a daemon managed by systemd I like to keep my configuration nimble enough that I can just start emacs and have an ad-hoc session for editing some files. [1] Or that's the goal. This has been a long running project for me, but early on in quarantine times, I've gotten things tightened up to the point that I feel comfortable using EDITOR=emacs just about all the time. On my (very old) computers, emacs starts and in well under 1 or 2 seconds, and does better on faster machines. If your emacs setup takes a long time to start up, this article is for you! Let's see if we can get the program to start faster.


The emacs-init-time function in emacs will tell you how long it took emacs to start up. This tends to be a bit under the actual start time, because some start-up activity gets pushed into various hooks, after startup. Just to keep an eye on things, I have a variant of the following as the first line in my config file:

(add-to-list 'after-init-hook
          (lambda ()
            (message (concat "emacs (" (number-to-string (emacs-pid)) ") started in " (emacs-init-time)))))

It's also possible to put additional information in this hook (and in reality I use something that pushes to a desktop notification tool, rather than just to message/logging.

You can also lower this number by putting more work into the after-init hook, but that sort of defeats the purpose: if you get the init time down to a second, but have 10 seconds of init-hook runtime, then that's probably not much of a win, particularly if the init-hook tasks are blocking.

The second thing to do is have a macro [2] available for use that allows to measure the runtime of a block of code, something like:

(defmacro with-timer (name &rest body)
  `(let ((time (current-time)))
     (message "%s: %.06f" ,name (float-time (time-since time)))))

You can then do something like:

(with-timer "mode-line-setup"

And then look in the *Message* buffer to see how long various things take so you know where focus your efforts.


  • use-package makes it possible to do much less during applciation startup, and makes it possible to load big lisp packages only when you're going to use them, and registers everything so you never feel the difference. Audit your use-package forms and ensure that they all declare one of the following forms, which insures that things are loaded upon use, rather than at start time:
    • :bind registers specific keybindings, but as autoloads so that the pacakge is only loaded when you use the keybinding.
    • :command registers function names as autoloads, like keybinding, so the commands/functions are available but again the package isn't loaded until it's used.
    • :mode attaches the package to a specific file extension or extensions so again, the package doesn't get loaded until you open a file of that type.
    • :after for loading a package after another package it depends on or is only used after.
    • :hook this allows you to associate something from this package into another package's hook, with the same effect of deferring loading of one package until after another is used.
  • Avoid having the default-scratch buffer trigger loading as much as possible. It's very tempting to have *scratch* default to org-mode or something, but if you keep it in fundamental-mode you can avoid loading most of your packages until you actually use them, or can avoid pulling in too much too quickly.
  • Keep an eye on startup both for GUI, terminal, and if you use daemons, daemon instances of emacs. There are some subtleties that may be useful or important. It's also the case that terminal startup times are often much less than GUI times.
  • Think about strategies for managing state-management (e.g. recentf session-mode and desktop-mode.) I've definitley had times when I really wanted emacs to be able to restart and leave me exactly where I was when I shut down. These session features are good, but often it's just crufty, and causes a lot of expense at start up time. I still use desktop and session, but less so.
  • Fancy themes and modelines come at some cost. I recently was able to save a lot of start up time by omiting a call to spaceline-compile in my configuration. Theme setup also can take a bit of time in GUI mode (I think!), but I dropped automatic theme configuration so that my instances would play better with terminal mode. [3]

Helpful Settings

I think of these four settings as the "start up behavior" settings from my config:

(setq inhibit-startup-echo-area-message "tychoish")
(setq inhibit-startup-message 't)
(setq initial-major-mode 'fundamental-mode)
(setq initial-scratch-message 'nil)

I've had the following jit settings in my config for a long time, and they tend to make things more peppy, which can only help during startup. This may also just be cargo-cult, stuff:

(setq jit-lock-stealth-time nil)
(setq jit-lock-defer-time nil)
(setq jit-lock-defer-time 0.05)
(setq jit-lock-stealth-load 200)

If you use desktop-mode to save state and re-open buffers, excluding some modes from this behavior is good. In my case, avoiding reopening (and rereading) potentially large org-mode buffers was helpful for me. The desktop-modes-not-to-save value is useful here, as in the following snippet from my configuration:

(add-to-list 'desktop-modes-not-to-save 'dired-mode)
(add-to-list 'desktop-modes-not-to-save 'Info-mode)
(add-to-list 'desktop-modes-not-to-save 'org-mode)
(add-to-list 'desktop-modes-not-to-save 'info-lookup-mode)
(add-to-list 'desktop-modes-not-to-save 'fundamental-mode)


[1]Ok, ok, I live with a vim user and the "quick startup time," situation is very appealing.
[2]I tweaked this based on what I found this on stack overflow which stole it from this listserv post.
[3]Mixed GUI/Terminal mode with themes can be kind of finicky because theme settings are global and color backgrounds often won't play well with terminal frames. You can say "if this is a gui mode," but that doesn't play well with daemons, and hooking into frame-creation has never worked as seamlessly as I would expect, because the of the execution context the hook functions (and slowing down frame creation can defeat part of the delight of the daemon.)

Tycho Emacs Config Kit

So I made a thing, or at least, I took a thing I've built and made it presentable for other people. I'm talking, of course, about my Emacs configuration.

Check it out at github.com/tychoish/.emacs.d! The README is pretty complete, and giving it a whirl is simple, just do something like:

mv ~/.emacs.d/ ~/emacs.d-archive
git clone --recurse-submodules git@github.com:tychoish/.emacs.d.git ~/.emacs.d/

If you're using Emacs 27, you might also be able to clone it into ~/.config/emacs, for similar effect. It doesn't matter much to me. Let me know what you think!

The tl;dr of "what's special about this config," is that, it has:

  • a good set of defaults out of the box.
  • a lot of great wiz-bang features enabled and configured.
  • very quick start times, thanks to lazy-loading of libraries.
  • great support for running as a daemon, and even running multiple daemons at once.

I've sporadically produced copies of my emacs config for other folks to use, but those were always ad hoc, and difficult to reproduce and maintain, and I've been working on and off to put more polish on things, so making it usable for other people seemed like a natural step at this point.

I hope other people find it useful, but also I think it's a good exercise for me in keeping things well maintained, and it doesn't bother me much one way or another.


I think a lot about developer experience: I've spent my career, thus far, working on infrastructure products (databases, CI systems, build tools, release engineering,) that help improve developer experience and productivity, and even my day-to-day work tends to focus mostly on problems that impact the way that my teams write software: system architecture, service construction, observability, test infrastructure, and similar.

No matter how you slice it, editor experience is a huge factor in people's experience, and can have a big impact on productivity, and there are so many different editors with wildly different strengths. Editors experience is also really hard: unlike other kinds of developer infrastructure (like buildsystems, or even programming languages) the field conceptualizes editors as personal: your choice in editor is seen to reflect on you (it probably doesn't), and your ability to use your editor well is seen to be a reflection of your skills as a developer (it isn't). It's also the case that because editors are so personal, it's very difficult to produce an editor with broad appeal, and the most successful editors tend to be very configurable and can easily lack defaults, which means that even great editors are terrible out of the box, which mostly affects would-be and new developers.

Nevertheless, time being able to have an editor that you're comfortable with and that you can use effectively without friction does make it easier to build software, so even if folks often conceptualize of editors in the wrong way, improving the editing experience is important. I think that there are two areas for improvement:

  • editor configurations should--to some extent--be maintained at the project (or metaproject) level, rather than on the level individual engineer. The hard part here is how to balance individual preference with providing a consistent experience, particularly for new developers. [1]
  • there should be more "starter kits" (like this one! or the many other starter kits, but also for (neo)vim, vscode, and others.) that help bootstrap the experience, while also figuring out ways to allow layering other project-based extensions on top of a base configuration.

Also, I want to give chemacs a shout out, for folks who want to try out other base configurations.

[1]There are two kinds of new developers with different experiences but some overlap: folks who have development experience in general but no experience with a specific project, and folks who are new to all development.
