Hello! Earlier this summer I was talking to a friend about how much I love using fish, and how I love that I don’t have to configure it. They said that they feel the same way about the helix text editor, and so I decided to give it a try. I’ve been using it for 3 months now and here are a few notes. why helix: language servers I think what motivated me to try Helix is that I’ve been trying to get a working language server setup (so I can do things like “go to definition”) and getting a setup that feels good in Vim or Neovim just felt like too much work. After using Vim/Neovim for 20 years, I’ve tried both “build my own custom configuration from scratch” and “use someone else’s pre-buld configuration system” and even though I love Vim I was excited about having things just work without having to work on my configuration at all. Helix comes with built in language server support, and it feels nice to be able to do things like “rename this symbol” in any language. the search is great One of my favourite things about Helix is the search! If I’m searching all the files in my repository for a string, it lets me scroll through the potential matching files and see the full context of the match, like this: For comparison, here’s what the vim ripgrep plugin I’ve been using looks like: There’s no context for what else is around that line. the quick reference is nice One thing I like about Helix is that when I press g, I get a little help popup telling me places I can go. I really appreciate this because I don’t often use the “go to definition” or “go to reference” feature and I often forget the keyboard shortcut. some vim -> helix translations Helix doesn’t have marks like ma, 'a, instead I’ve been using Ctrl+O and Ctrl+I to go back (or forward) to the last cursor locarion I think Helix does have macros, but I’ve been using multiple cursors in every case that I would have previously used a macro. I like multiple cursors a lot more than writing macros all the time. If I want to batch change something in the document, my workflow is to press % (to highlight everything), then s to select (with a regex) the things I want to change, then I can just edit all of them as needed. Helix doesn’t have tabs, instead it has a nice buffer switcher (<space>b) I can use to switch to the buffer I want some helix annoyances Here’s everything that’s annoyed me about Helix so far. I like the way Helix’s :reflow works much less than how vim reflows text with gq. It doesn’t work as well with lists. (github issue) If I’m making a Markdown list, pressing “enter” at the end of a list item won’t continue the list. There’s a partial workaround for bulleted lists but I don’t know one for numbered lists. No persistent undo yet: in vim I could use an undofile so that I could undo changes even after quitting. Helix doesn’t have that feature yet. (github PR) Helix doesn’t autoreload files after they change on disk, I have to run :reload-all (:ra<tab>) to manually reload them. Not a big deal. Sometimes it crashes: every week or so there’s a segfault and the editor crashes. Someone mentioned that this might have something to do with the fact that I edit a lot of Markdown, not sure. This doesn’t bother me that much though, I can just reopen it. The “markdown list” and reflowing issues come up a lot for me because I spend a lot of time editing Markdown lists, but I keep using Helix anyway so I guess they can’t be making me that mad. switching was easier than I thought I was worried that relearning 20 years of Vim muscle memory would be really hard. It turned out to be easier than I expected, I started using Helix on a vacation for a little low-stakes coding project I was doing on the side and after a week or two it didn’t feel so disorienting anymore. I think it might be hard to switch back and forth between Vim and Helix, but I haven’t needed to use Vim recently so I don’t know if that’ll ever become an issue for me. The first time I tried Helix I tried to force it to use keybindings that were more similar to Vim and that did not work for me. Just learning the “Helix way” was a lot easier. There are still some things that throw me off: for example w in vim and w in Helix don’t have the same idea of what a “word” is (the Helix one includes the space after the word, the Vim one doesn’t). using a terminal-based text editor For many years I’d mostly been using a GUI version of vim/neovim, so switching to actually using an editor in the terminal was a bit of an adjustment. I ended up deciding on: Every project gets its own terminal window, and all of the tabs in that window (mostly) have the same working directory I make my Helix tab the first tab in the terminal window It works pretty well, I might actually like it better than my previous workflow. my configuration I appreciate that my configuration is really simple, compared to my neovim configuration which is hundreds of lines. It’s mostly just 4 keyboard shortcuts. theme = "solarized_light" [editor] # Sync clipboard with system clipboard default-yank-register = "+" [keys.normal] # I didn't like that Ctrl+C was the default "toggle comments" shortcut "#" = "toggle_comments" # I didn't feel like learning a different way # to go to the beginning/end of a line so # I remapped ^ and $ "^" = "goto_first_nonwhitespace" "$" = "goto_line_end" [keys.select] "^" = "goto_first_nonwhitespace" "$" = "goto_line_end" [keys.normal.space] # I write a lot of text so I need to constantly reflow, # and missed vim's `gq` shortcut l = ":reflow" There’s a separate languages.toml configuration where I set some language preferences, like turning off autoformatting. For example, here’s my Python configuration: [[language]] name = "python" formatter = { command = "black", args = ["--stdin-filename", "%{buffer_name}", "-"] } language-servers = ["pyright"] auto-format = false we’ll see how it goes Three months is not that long, and it’s possible that I’ll decide to go back to Vim at some point. For example, I wrote a post about switching to nix a while back but after maybe 8 months I switched back to Homebrew (though I’m still using NixOS to manage one little server, and I’m still satisfied with that).

I have never been a C programmer but every so often I need to compile a C/C++ program from source. This has been kind of a struggle for me: for a long time, my approach was basically “install the dependencies, run make, if it doesn’t work, either try to find a binary someone has compiled or give up”. “Hope someone else has compiled it” worked pretty well when I was running Linux but since I’ve been using a Mac for the last couple of years I’ve been running into more situations where I have to actually compile programs myself. So let’s talk about what you might have to do to compile a C program! I’ll use a couple of examples of specific C programs I’ve compiled and talk about a few things that can go wrong. Here are three programs we’ll be talking about compiling: paperjam sqlite qf (a pager you can run to quickly open files from a search with rg -n THING | qf) step 1: install a C compiler This is pretty simple: on an Ubuntu system if I don’t already have a C compiler I’ll install one with: sudo apt-get install build-essential This installs gcc, g++, and make. The situation on a Mac is more confusing but it’s something like “install xcode command line tools”. step 2: install the program’s dependencies Unlike some newer programming languages, C doesn’t have a dependency manager. So if a program has any dependencies, you need to hunt them down yourself. Thankfully because of this, C programmers usually keep their dependencies very minimal and often the dependencies will be available in whatever package manager you’re using. There’s almost always a section explaining how to get the dependencies in the README, for example in paperjam’s README, it says: To compile PaperJam, you need the headers for the libqpdf and libpaper libraries (usually available as libqpdf-dev and libpaper-dev packages). You may need a2x (found in AsciiDoc) for building manual pages. So on a Debian-based system you can install the dependencies like this. sudo apt install -y libqpdf-dev libpaper-dev If a README gives a name for a package (like libqpdf-dev), I’d basically always assume that they mean “in a Debian-based Linux distro”: if you’re on a Mac brew install libqpdf-dev will not work. I still have not 100% gotten the hang of developing on a Mac yet so I don’t have many tips there yet. I guess in this case it would be brew install qpdf if you’re using Homebrew. step 3: run ./configure (if needed) Some C programs come with a Makefile and some instead come with a script called ./configure. For example, if you download sqlite’s source code, it has a ./configure script in it instead of a Makefile. My understanding of this ./configure script is: You run it, it prints out a lot of somewhat inscrutable output, and then it either generates a Makefile or fails because you’re missing some dependency The ./configure script is part of a system called autotools that I have never needed to learn anything about beyond “run it to generate a Makefile”. I think there might be some options you can pass to get the ./configure script to produce a different Makefile but I have never done that. step 4: run make The next step is to run make to try to build a program. Some notes about make: Sometimes you can run make -j8 to parallelize the build and make it go faster It usually prints out a million compiler warnings when compiling the program. I always just ignore them. I didn’t write the software! The compiler warnings are not my problem. compiler errors are often dependency problems Here’s an error I got while compiling paperjam on my Mac: /opt/homebrew/Cellar/qpdf/12.0.0/include/qpdf/InputSource.hh:85:19: error: function definition does not declare parameters 85 | qpdf_offset_t last_offset{0}; | ^ Over the years I’ve learned it’s usually best not to overthink problems like this: if it’s talking about qpdf, there’s a good change it just means that I’ve done something wrong with how I’m including the qpdf dependency. Now let’s talk about some ways to get the qpdf dependency included in the right way. the world’s shortest introduction to the compiler and linker Before we talk about how to fix dependency problems: building C programs is split into 2 steps: Compiling the code into object files (with gcc or clang) Linking those object files into a final binary (with ld) It’s important to know this when building a C program because sometimes you need to pass the right flags to the compiler and linker to tell them where to find the dependencies for the program you’re compiling. make uses environment variables to configure the compiler and linker If I run make on my Mac to install paperjam, I get this error: c++ -o paperjam paperjam.o pdf-tools.o parse.o cmds.o pdf.o -lqpdf -lpaper ld: library 'qpdf' not found This is not because qpdf is not installed on my system (it actually is!). But the compiler and linker don’t know how to find the qpdf library. To fix this, we need to: pass "-I/opt/homebrew/include" to the compiler (to tell it where to find the header files) pass "-L/opt/homebrew/lib -liconv" to the linker (to tell it where to find library files and to link in iconv) And we can get make to pass those extra parameters to the compiler and linker using environment variables! To see how this works: inside paperjam’s Makefile you can see a bunch of environment variables, like LDLIBS here: paperjam: $(OBJS) $(LD) -o $@ $^ $(LDLIBS) Everything you put into the LDLIBS environment variable gets passed to the linker (ld) as a command line argument. secret environment variable: CPPFLAGS Makefiles sometimes define their own environment variables that they pass to the compiler/linker, but make also has a bunch of “implicit” environment variables which it will automatically pass to the C compiler and linker. There’s a full list of implicit environment variables here, but one of them is CPPFLAGS, which gets automatically passed to the C compiler. (technically it would be more normal to use CXXFLAGS for this, but this particular Makefile hardcodes CXXFLAGS so setting CPPFLAGS was the only way I could find to set the compiler flags without editing the Makefile) how to use CPPFLAGS and LDLIBS to fix this compiler error Now that we’ve talked about how CPPFLAGS and LDLIBS get passed to the compiler and linker, here’s the final incantation that I used to get the program to build successfully! CPPFLAGS="-I/opt/homebrew/include" LDLIBS="-L/opt/homebrew/lib -liconv" make paperjam This passes -I/opt/homebrew/include to the compiler and -L/opt/homebrew/lib -liconv to the linker. Also I don’t want to pretend that I “magically” knew that those were the right arguments to pass, figuring them out involved a bunch of confused Googling that I skipped over in this post. I will say that: the -I compiler flag tells the compiler which directory to find header files in, like /opt/homebrew/include/qpdf/QPDF.hh the -L linker flag tells the linker which directory to find libraries in, like /opt/homebrew/lib/libqpdf.a the -l linker flag tells the linker which libraries to link in, like -liconv means “link in the iconv library”, or -lm means “link math” tip: how to just build 1 specific file: make $FILENAME Yesterday I discovered this cool tool called qf which you can use to quickly open files from the output of ripgrep. qf is in a big directory of various tools, but I only wanted to compile qf. So I just compiled qf, like this: make qf Basically if you know (or can guess) the output filename of the file you’re trying to build, you can tell make to just build that file by running make $FILENAME tip: look at how other packaging systems built the same C program If you’re having trouble building a C program, maybe other people had problems building it too! Every Linux distribution has build files for every package that they build, so even if you can’t install packages from that distribution directly, maybe you can get tips from that Linux distro for how to build the package. Realizing this (thanks to my friend Dave) was a huge ah-ha moment for me. For example, this line from the nix package for paperjam says: env.NIX_LDFLAGS = lib.optionalString stdenv.hostPlatform.isDarwin "-liconv"; This is basically saying “pass the linker flag -liconv to build this on a Mac”, so that’s a clue we could use to build it. That same file also says env.NIX_CFLAGS_COMPILE = "-DPOINTERHOLDER_TRANSITION=1";. I’m not sure what this means, but when I try to build the paperjam package I do get an error about something called a PointerHolder, so I guess that’s somehow related to the “PointerHolder transition”. step 5: installing the binary Once you’ve managed to compile the program, probably you want to install it somewhere! Some Makefiles have an install target that let you install the tool on your system with make install. I’m always a bit scared of this (where is it going to put the files? what if I want to uninstall them later?), so if I’m compiling a pretty simple program I’ll often just manually copy the binary to install it instead, like this: cp qf ~/bin step 6: maybe make your own package! Once I figured out how to do all of this, I realized that I could use my new make knowledge to contribute a paperjam package to Homebrew! Then I could just brew install paperjam on future systems. The good thing is that even if the details of how all of the different packaging systems, they fundamentally all use C compilers and linkers. it can be useful to understand a little about C even if you’re not a C programmer I think all of this is an interesting example of how it can useful to understand some basics of how C programs work (like “they have header files”) even if you’re never planning to write a nontrivial C program if your life. It feels good to have some ability to compile C/C++ programs myself, even though I’m still not totally confident about all of the compiler and linker flags and I still plan to never learn anything about how autotools works other than “you run ./configure to generate the Makefile”. Also one important thing I left out is LD_LIBRARY_PATH / DYLD_LIBRARY_PATH (which you use to tell the dynamic linker at runtime where to find dynamically linked files) because I can’t remember the last time I ran into an LD_LIBRARY_PATH issue and couldn’t find an example.

A few weeks ago I ran a terminal survey (you can read the results here) and at the end I asked: What’s the most frustrating thing about using the terminal for you? 1600 people answered, and I decided to spend a few days categorizing all the responses. Along the way I learned that classifying qualitative data is not easy but I gave it my best shot. I ended up building a custom tool to make it faster to categorize everything. As with all of my surveys the methodology isn’t particularly scientific. I just posted the survey to Mastodon and Twitter, ran it for a couple of days, and got answers from whoever happened to see it and felt like responding. Here are the top categories of frustrations! I think it’s worth keeping in mind while reading these comments that 40% of people answering this survey have been using the terminal for 21+ years 95% of people answering the survey have been using the terminal for at least 4 years These comments aren’t coming from total beginners. Here are the categories of frustrations! The number in brackets is the number of people with that frustration. Honestly I don’t how how interesting this is to other people – I’m just writing this up for myself because I’m trying to write a zine about the terminal and I wanted to get a sense for what people are having trouble with. remembering syntax (115) People talked about struggles remembering: the syntax for CLI tools like awk, jq, sed, etc the syntax for redirects keyboard shortcuts for tmux, text editing, etc One example comment: There are just so many little “trivia” details to remember for full functionality. Even after all these years I’ll sometimes forget where it’s 2 or 1 for stderr, or forget which is which for > and >>. switching terminals is hard (91) People talked about struggling with switching systems (for example home/work computer or when SSHing) and running into: OS differences in keyboard shortcuts (like Linux vs Mac) systems which don’t have their preferred text editor (“no vim” or “only vim”) different versions of the same command (like Mac OS grep vs GNU grep) no tab completion a shell they aren’t used to (“the subtle differences between zsh and bash”) as well as differences inside the same system like pagers being not consistent with each other (git diff pagers, other pagers). One example comment: I got used to fish and vi mode which are not available when I ssh into servers, containers. color (85) Lots of problems with color, like: programs setting colors that are unreadable with a light background color finding a colorscheme they like (and getting it to work consistently across different apps) color not working inside several layers of SSH/tmux/etc not liking the defaults not wanting color at all and struggling to turn it off This comment felt relatable to me: Getting my terminal theme configured in a reasonable way between the terminal emulator and fish (I did this years ago and remember it being tedious and fiddly and now feel like I’m locked into my current theme because it works and I dread touching any of that configuration ever again). keyboard shortcuts (84) Half of the comments on keyboard shortcuts were about how on Linux/Windows, the keyboard shortcut to copy/paste in the terminal is different from in the rest of the OS. Some other issues with keyboard shortcuts other than copy/paste: using Ctrl-W in a browser-based terminal and closing the window the terminal only supports a limited set of keyboard shortcuts (no Ctrl-Shift-, no Super, no Hyper, lots of ctrl- shortcuts aren’t possible like Ctrl-,) the OS stopping you from using a terminal keyboard shortcut (like by default Mac OS uses Ctrl+left arrow for something else) issues using emacs in the terminal backspace not working (2) other copy and paste issues (75) Aside from “the keyboard shortcut for copy and paste is different”, there were a lot of OTHER issues with copy and paste, like: copying over SSH how tmux and the terminal emulator both do copy/paste in different ways dealing with many different clipboards (system clipboard, vim clipboard, the “middle click” keyboard on Linux, tmux’s clipboard, etc) and potentially synchronizing them random spaces added when copying from the terminal pasting multiline commands which automatically get run in a terrifying way wanting a way to copy text without using the mouse discoverability (55) There were lots of comments about this, which all came down to the same basic complaint – it’s hard to discover useful tools or features! This comment kind of summed it all up: How difficult it is to learn independently. Most of what I know is an assorted collection of stuff I’ve been told by random people over the years. steep learning curve (44) A lot of comments about it generally having a steep learning curve. A couple of example comments: After 15 years of using it, I’m not much faster than using it than I was 5 or maybe even 10 years ago. and That I know I could make my life easier by learning more about the shortcuts and commands and configuring the terminal but I don’t spend the time because it feels overwhelming. history (42) Some issues with shell history: history not being shared between terminal tabs (16) limits that are too short (4) history not being restored when terminal tabs are restored losing history because the terminal crashed not knowing how to search history One example comment: It wasted a lot of time until I figured it out and still annoys me that “history” on zsh has such a small buffer; I have to type “history 0” to get any useful length of history. bad documentation (37) People talked about: documentation being generally opaque lack of examples in man pages programs which don’t have man pages Here’s a representative comment: Finding good examples and docs. Man pages often not enough, have to wade through stack overflow scrollback (36) A few issues with scrollback: programs printing out too much data making you lose scrollback history resizing the terminal messes up the scrollback lack of timestamps GUI programs that you start in the background printing stuff out that gets in the way of other programs’ outputs One example comment: When resizing the terminal (in particular: making it narrower) leads to broken rewrapping of the scrollback content because the commands formatted their output based on the terminal window width. “it feels outdated” (33) Lots of comments about how the terminal feels hampered by legacy decisions and how users often end up needing to learn implementation details that feel very esoteric. One example comment: Most of the legacy cruft, it would be great to have a green field implementation of the CLI interface. shell scripting (32) Lots of complaints about POSIX shell scripting. There’s a general feeling that shell scripting is difficult but also that switching to a different less standard scripting language (fish, nushell, etc) brings its own problems. Shell scripting. My tolerance to ditch a shell script and go to a scripting language is pretty low. It’s just too messy and powerful. Screwing up can be costly so I don’t even bother. more issues Some more issues that were mentioned at least 10 times: (31) inconsistent command line arguments: is it -h or help or –help? (24) keeping dotfiles in sync across different systems (23) performance (e.g. “my shell takes too long to start”) (20) window management (potentially with some combination of tmux tabs, terminal tabs, and multiple terminal windows. Where did that shell session go?) (17) generally feeling scared/uneasy (“The debilitating fear that I’m going to do some mysterious Bad Thing with a command and I will have absolutely no idea how to fix or undo it or even really figure out what happened”) (16) terminfo issues (“Having to learn about terminfo if/when I try a new terminal emulator and ssh elsewhere.”) (16) lack of image support (sixel etc) (15) SSH issues (like having to start over when you lose the SSH connection) (15) various tmux/screen issues (for example lack of integration between tmux and the terminal emulator) (15) typos & slow typing (13) the terminal getting messed up for various reasons (pressing Ctrl-S, cating a binary, etc) that’s all! I’m not going to make a lot of commentary on these results, but here are a couple of categories that feel related to me: remembering syntax & history (often the thing you need to remember is something you’ve run before!) discoverability & the learning curve (the lack of discoverability is definitely a big part of what makes it hard to learn)

Hello! Recently I ran a terminal survey and I asked people what frustrated them. One person commented: There are so many pieces to having a modern terminal experience. I wish it all came out of the box. My immediate reaction was “oh, getting a modern terminal experience isn’t that hard, you just need to….”, but the more I thought about it, the longer the “you just need to…” list got, and I kept thinking about more and more caveats. So I thought I would write down some notes about what it means to me personally to have a “modern” terminal experience and what I think can make it hard for people to get there. what is a “modern terminal experience”? Here are a few things that are important to me, with which part of the system is responsible for them: multiline support for copy and paste: if you paste 3 commands in your shell, it should not immediatly run them all! That’s scary! (shell, terminal emulator) infinite shell history: if I run a command in my shell, it should be saved forever, not deleted after 500 history entries or whatever. Also I want commands to be saved to the history immediately when I run them, not only when I exit the shell session (shell) a useful prompt: I can’t live without having my current directory and current git branch in my prompt (shell) 24-bit colour: this is important to me because I find it MUCH easier to theme neovim with 24-bit colour support than in a terminal with only 256 colours (terminal emulator) clipboard integration between vim and my operating system so that when I copy in Firefox, I can just press p in vim to paste (text editor, maybe the OS/terminal emulator too) good autocomplete: for example commands like git should have command-specific autocomplete (shell) having colours in ls (shell config) a terminal theme I like: I spend a lot of time in my terminal, I want it to look nice and I want its theme to match my terminal editor’s theme. (terminal emulator, text editor) automatic terminal fixing: If a programs prints out some weird escape codes that mess up my terminal, I want that to automatically get reset so that my terminal doesn’t get messed up (shell) keybindings: I want Ctrl+left arrow to work (shell or application) being able to use the scroll wheel in programs like less: (terminal emulator and applications) There are a million other terminal conveniences out there and different people value different things, but those are the ones that I would be really unhappy without. how I achieve a “modern experience” My basic approach is: use the fish shell. Mostly don’t configure it, except to: set the EDITOR environment variable to my favourite terminal editor alias ls to ls --color=auto use any terminal emulator with 24-bit colour support. In the past I’ve used GNOME Terminal, Terminator, and iTerm, but I’m not picky about this. I don’t really configure it other than to choose a font. use neovim, with a configuration that I’ve been very slowly building over the last 9 years or so (the last time I deleted my vim config and started from scratch was 9 years ago) use the base16 framework to theme everything some “out of the box” options for a “modern” experience What if you want a nice experience, but don’t want to spend a lot of time on configuration? Figuring out how to configure vim in a way that I was satisfied with really did take me like ten years, which is a long time! My best ideas for how to get a reasonable terminal experience with minimal config are: shell: either fish or zsh with oh-my-zsh terminal emulator: almost anything with 24-bit colour support, for example all of these are popular: linux: GNOME Terminal, Konsole, Terminator, xfce4-terminal mac: iTerm (Terminal.app doesn’t have 256-colour support) cross-platform: kitty, alacritty, wezterm, or ghostty shell config: set the EDITOR environment variable to your favourite terminal text editor maybe alias ls to ls --color=auto text editor: this is a tough one, maybe micro or helix? I haven’t used either of them seriously but they both seem like very cool projects and I think it’s amazing that you can just use all the usual GUI editor commands (Ctrl-C to copy, Ctrl-V to paste, Ctrl-A to select all) in micro and they do what you’d expect. I would probably try switching to helix except that retraining my vim muscle memory seems way too hard and I have a working vim config already. Personally I wouldn’t use xterm, rxvt, or Terminal.app as a terminal emulator, because I’ve found in the past that they’re missing core features (like 24-bit colour in Terminal.app’s case) that make the terminal harder to use for me. I don’t want to pretend that getting a “modern” terminal experience is easier than it is though – I think there are two issues that make it hard. Let’s talk about them! issue 1 with getting to a “modern” experience: the shell bash and zsh are by far the two most popular shells, and neither of them provide a default experience that I would be happy using out of the box, for example: you need to customize your prompt they don’t come with git completions by default, you have to set them up by default, bash only stores 500 (!) lines of history and (at least on Mac OS) zsh is only configured to store 2000 lines, which is still not a lot I find bash’s tab completion very frustrating, if there’s more than one match then you can’t tab through them And even though I love fish, the fact that it isn’t POSIX does make it hard for a lot of folks to make the switch. Of course it’s totally possible to learn how to customize your prompt in bash or whatever, and it doesn’t even need to be that complicated (in bash I’d probably start with something like export PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ ', or maybe use starship). But each of these “not complicated” things really does add up and it’s especially tough if you need to keep your config in sync across several systems. An extremely popular solution to getting a “modern” shell experience is oh-my-zsh. It seems like a great project and I know a lot of people use it very happily, but I’ve struggled with configuration systems like that in the past – it looks like right now the base oh-my-zsh adds about 3000 lines of config, and often I find that having an extra configuration system makes it harder to debug what’s happening when things go wrong. I personally have a tendency to use the system to add a lot of extra plugins, make my system slow, get frustrated that it’s slow, and then delete it completely and write a new config from scratch. issue 2 with getting to a “modern” experience: the text editor In the terminal survey I ran recently, the most popular terminal text editors by far were vim, emacs, and nano. I think the main options for terminal text editors are: use vim or emacs and configure it to your liking, you can probably have any feature you want if you put in the work use nano and accept that you’re going to have a pretty limited experience (for example as far as I can tell if you want to copy some text from nano and put it in your system clipboard you just… can’t?) use micro or helix which seem to offer a pretty good out-of-the-box experience, potentially occasionally run into issues with using a less mainstream text editor just avoid using a terminal text editor as much as possible, maybe use VSCode, use VSCode’s terminal for all your terminal needs, and mostly never edit files in the terminal issue 3: individual applications The last issue is that sometimes individual programs that I use are kind of annoying. For example on my Mac OS machine, /usr/bin/sqlite3 doesn’t support the Ctrl+Left Arrow keyboard shortcut. Fixing this to get a reasonable terminal experience in SQLite was a little complicated, I had to: realize why this is happening (Mac OS won’t ship GNU tools, and “Ctrl-Left arrow” support comes from GNU readline) find a workaround (install sqlite from homebrew, which does have readline support) adjust my environment (put Homebrew’s sqlite3 in my PATH) I find that debugging application-specific issues like this is really not easy and often it doesn’t feel “worth it” – often I’ll end up just dealing with various minor inconveniences because I don’t want to spend hours investigating them. The only reason I was even able to figure this one out at all is that I’ve been spending a huge amount of time thinking about the terminal recently. A big part of having a “modern” experience using terminal programs is just using newer terminal programs, for example I can’t be bothered to learn a keyboard shortcut to sort the columns in top, but in htop I can just click on a column heading with my mouse to sort it. So I use htop instead! But discovering new more “modern” command line tools isn’t easy (though I made a list here), finding ones that I actually like using in practice takes time, and if you’re SSHed into another machine, they won’t always be there. everything affects everything else Something I find tricky about configuring my terminal to make everything “nice” is that changing one seemingly small thing about my workflow can really affect everything else. For example right now I don’t use tmux. But if I needed to use tmux again (for example because I was doing a lot of work SSHed into another machine), I’d need to think about a few things, like: if I wanted tmux’s copy to synchronize with my system clipboard over SSH, I’d need to make sure that my terminal emulator has OSC 52 support if I wanted to use iTerm’s tmux integration (which makes tmux tabs into iTerm tabs), I’d need to change how I configure colours – right now I set them with a shell script that I run when my shell starts, but that means the colours get lost when restoring a tmux session. and probably more things I haven’t thought of. “Using tmux means that I have to change how I manage my colours” sounds unlikely, but that really did happen to me and I decided “well, I don’t want to change how I manage colours right now, so I guess I’m not using that feature!”. It’s also hard to remember which features I’m relying on – for example maybe my current terminal does have OSC 52 support and because copying from tmux over SSH has always Just Worked I don’t even realize that that’s something I need, and then it mysteriously stops working when I switch terminals. change things slowly Personally even though I think my setup is not that complicated, it’s taken me 20 years to get to this point! Because terminal config changes are so likely to have unexpected and hard-to-understand consequences, I’ve found that if I change a lot of terminal configuration all at once it makes it much harder to understand what went wrong if there’s a problem, which can be really disorienting. So I prefer to make pretty small changes, and accept that changes can might take me a REALLY long time to get used to. For example I switched from using ls to eza a year or two ago and while I think I like it I’m still not quite sure about it. getting a “modern” terminal is not that easy Trying to explain how “easy” it is to configure your terminal really just made me think that it’s kind of hard and that I still sometimes get confused. I’ve found that there’s never one perfect way to configure things in the terminal that will be compatible with every single other thing. I just need to try stuff, figure out some kind of locally stable state that works for me, and accept that if I start using a new tool it might disrupt the system and I might need to rethink things.
