Alacritty wsl

With Homebrew, command line tools just work. Python and Node dev environments just work. It supports tabs, splits, mouse mode and has a pretty color scheme to boot:. I really just wanted the equivalent of iTerm2 in Windows. I wanted to utilize WSL not Cygwin and at a minimum needed:. I think I tried every major Windows terminal app I could find. Each had their own drawbacks and I eventually gave up.

Some of the ones I tried:. Unfortunately, when I started using Tmux it became a problem. I could never get mouse mode to work scrolling or selecting panesand resizing windows was problematic.

Not gonna cut it for me though I still do use Cmder regularly for when I need to run Windows cmd. That opened up a ton of possibilities, and one of my favorite Linux terminals, Terminatorwas now a possibility! After researching, it seemed the two most popular options are:. I went with VcXSrv since it looked like it was more actively maintained, but I tried both and they work the same.

After installing, VcXsrv creates a desktop shortcut to start the server in multi-window mode through the following command:. Once VcXsrv was installed and configured to allow access from After it installed, all that was left was to try launching it by specifying the X Display to connect to The next step I did was install Zsh with oh-my-zsh.

Installation is straightfoward:. To get around that, I add this to the end of my. The next thing I chose to do was change the default Terminator colorscheme to Solarized Dark. The easiest way to do this IMO, is to use the awesome node package basebuilder. I found Solarized dircolors on Github and downloaded them to.Powerline Shell uses custom patched fonts for the glyph icons it uses. Contrary to the documentation, you actually need to install these fonts in Windows and set the console host font to one of them.

This is pretty simple to do; first clone the repository, install the fonts and delete the repository. When you run the install script, windows will act a little weird as it installs each font individually popping up a dialog for each. After several of these dialogs you should be good to go.

Next open bash and click the icon in the upper left corner and select Properties. Change to the Font tab and select one of the patched fonts you just installed.

They will all say "for Powerline" so just pick one of those. This post is assuming that you have a clean install of Windows Subsystem for Linux. So, we need to do somethings to get our bash environment ready for Powerline Shell. I have covered this topic in the past, so I will just run through the commands here. Check the previous post for screenshots and hand holding. We need to update apt-get, install build tools and git. The commands are as follows. Run these in your bash prompt.

The only difference here between the other post and these commands is I have added the installation of python and pip to the mix. Powerline Shell is a set of python scripts we will need them.

Windows の Terminal を変えた

First we need to clone the Powerline Shell repository. So run these commands to pull the source. Finally, we need to update our. We can use vim to accomplish this. Don't worry if vim is scary I'll walk you through it.Alacrittythe OpenGL terminal emulator written in Rust, has landed support for scrollback in version 0.

At the same time, scrolling performance has improved, and we are beginning to version our releases and maintain a changelog. This post provides instructions for getting v0. The officially supported way to get Alacritty is, for now, building from source. First, add the scrolling section which includes things like how much history to store, how many lines to scroll per mouse wheel interval, and whether to automatically return to the most recent lines when new data is output.

A big concern from the community around introducing scrollback into Alacritty was that performance would suffer. To guide our development efforts, we wrote a tool called vtebench which is a tool for benchmarking terminal emulators.

Using vtebenchwe are able to test use cases like scrolling through a large text file, scrolling through a large text file as if in vim or tmuxand also processing large amounts of screen updates as in vim or tmux. In the following sections are data for each of these three benchmarks with some commentary around what exactly the benchmark is exercising. Each benchmark is presented twice, once for a macOS environment and once for a Linux environment and comparing against common terminals of the respective platform.

Three runs were made to warm caches, fill buffers, etc. The reported numbers are the result of averaging 10 runs following the three warm-up runs. The exact vtebench commands used to generate test files follow charts at the end of each section.

This data allows us to zero in on performance of adding new lines of output and managing the scrollback buffer. Alacritty is over 9x faster than the next terminal emulator on macOS for scrolling, and performance has improved 5x since the previous release. Alacritty is about 2. Similarly, vim uses a scrolling region to keep its status bar fixed while scrolling through a file. Alacritty is over 4. Alacritty is about 1. The final benchmark is intended to emulate working within a vim buffer or drawing in a tmux pane.

In this scenario, a random location on the screen is selected, a random color is chosen, and some amount of text is drawn, over and over. Interestingly, this is the one place where Alacritty performance was reduced compared to the pre-scrollback version. This was a direct result of a trade for a major scrolling performance optimization, and given that our alt-screen write performance is still great, we were happy to accept this trade-off.

Since launching, Alacritty has found its way into several package managers, and a common problem that packagers have run into is knowing the right time to publish a new version. Going forward, larger features like scrollback will increment the minor version number; bug fixes, minor improvements, and dependency updates will be incrementing the patch version. Maintaining a changelog has been a common request from users, and versioned releases enable us to keep one.

We will be following the conventions outlined by keep a changelog. There are many people who have had a big impact on Alacritty getting a high quality implementation of scrollback, and I would like to take a moment to thank them.Windows Subsystem for Linux WSL has been on the frontpage for sometime because of its bold claim to bridge the gap between linux and windows experience in a completely new way.

The next post will include my take on making the environment reproducable. I started using Unix around with Solaris 2. Therefore I consider myself a very difficult person to satisfy when it comes to my daily working environment. I am quite picky about my editors, settings, fonts, terminal, shells, habits, desktops or lack of a desktop, I work on maximized windows.

How far you can go, depends on the version of WSL you pick. Currently there are 2 versions of it. WSL 2 toolchain Windows 10 buils or later allows users to have both versions their systemso you are free to experiment with both. Given historical support for POSIX subsystem, I suppose extending that to cover all system calls was the first choice.

WSL 2 on the other hand runs a Microsoft maintained, real Linux kernel inside a heavily optimized, lightweight Hyper-V subset. You might wonder how is that without overhead of a virtual machine, if it still involves a Hyper-V and then become tempted to use WSL 1 to avoid virtualization. Overhead of a virtual machine is not just about the resources consumed. I am much less worried about resources. Overhead I see is more about management of it. Ultimately, user has to make some manual configurations, manage partitions, think about resizing, updating, backing up, reinstalling in case of a problem.

I have always maintained my vm environment via Vagrant and it paid off, but If I can simplify further, I would do it. I do not want to manage virtual machines.

Following is all you will have in WSL Therefore, if you a have code or use case that requires certain devices, proc files, you will hit a blocker. It happened to me once with an npm module please don't ask This is not a problem for everybody though. It's just, there is no workaround, you have to switch to WSL 2 or use a virtual machine.

WSL 2 on the other hand, uses a real kernel so there is no such problem. This is one of the biggest complains about WSL 1. Even your oh-my-zsh prompts will suffer when you traverse Git directories. I ran mvn clean package twice for each, first one to make sure dependencies are found locally in the second run. I know how much things can differ when it comes to building a software, so again, this is not a conclusion.

Both WSL 1 and 2 lets you not just access files from both sides, but also allows executing binaries. This is a huge convenience compared to traditional ways of running Linux inside Windows via hypervisors or docker. However, accessing Linux file system from Windows using explorer or plain scripts works different between WSL 1 and 2. You can just open PowerShell or explorer and browse to it. However, accessing files directly from Windows is not recommended.

I occasionally did that to make brief editings and avoided writing from both sides.

WSL + Alacritty で Powerline を使う

However, WSL 2 content is in a disk image owned by the kernel and access is done over the network via 9P Protocol. This is definitely inconvenient compared to WSL 1 experince.

WSL both 1 and 2 does not have a framebuffer or a dri device. Therefore you always have to run an X server on Windows e. XmingXVcxsrv This works pretty well. But why do I say WSL 1 is better in this? Just because of convenience.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. Have a question about this project?

Getting graphics rendering out of the WSL would be pretty tricky. At the moment building on Windows bails out at servo-fontconfig-sys - should I open an issue for this? I managed to build this on WSL Ubuntu Hey guys. I'm attempting to implement a working windows build in my spare time. I'm a Rust n00b, so excuse the roughness Using the links rigtorp posted, and a bit of digging, I think that I have font rendering working for windows.

A very rough pass of something that I think might work if I'm lucky The module compiles at least But I have other problems that prevent me from testing it:. You seem to be pegged to a particular commit of jwilm 's fork of Glutin. This fork does not compile on windows. A function that doesn't even exist in later commits, btw. Why are you pegged to an old commit of your Glutin fork jwilm? Bumping up to the latest commit of the Glutin fork successfully compiles on windows, but then the config.

Any thoughts on getting Glutin to work on the windows build? Or is the correct action to bump up to the latest Glutin and fix the issues with the event handling? There is also a whole bunch of unix specific stuff that the code goes looking for, which obviously fail to compile, but that seems more straightforward to fix, or at least I consider that to be a battle for another day lol.Dive into Docker takes you from "What is Docker?

It's packed with best practices and examples. Updated on November 6th, in dev-environment. What Makes the Perfect Terminal? Is Hyper Worth Using? I tend to stick with what I have until I have a very real reason to switch and lately I found myself wanting to switch away from ConEmu for a few reasons.

For example I could have a single ConEmu terminal open, split into 3 panes and then have 2 more terminals off to the side and ConEmu will take my i5 3. That is purely idling with no work being done in the terminal at all. Nothing more than a default basic prompt and a blinking cursor.

Also as you open more terminal sessions, the CPU load continues to climb. If your CPU is under high stress, it could add little pops and clicks to your audio. The author basically says not to just the mouse, but use hotkeys. Imagine typing something on the terminal, but you want to move the cursor a few characters back so you can edit some flag and then re-run a command. Well, this bug will cause your cursor to jump to the end of the line every time you press a key.

It makes it impossible to edit a command. I found myself literally copying a command, pasting it into my code editor, editing it there and then pasting it back. Not cool. Seriously, fuck that. I have nothing against ConEmu or the author. If it checks all of those boxes, you can count on me using it until the end of time. This has been an abnormal month when it comes to terminal usage.

I even kept my terminal windows open overnight for 18 days straight. Hyper is solid in the sense that it never crashed or had a show stopping bug.

Configuring wsltty Which Is My Favorite Windows WSL Terminal

I was running a Canary build too, which is the latest semi-stable pre-release. It was 0. Of course it spiked the CPU while I was opening them all quickly, but no one just spam opens 20 in a row like a maniac and even then the spike only lasted for a few seconds. As for memory, every single Hyper related process for 20 terminals added together used mb of RAM. I do a majority of my coding during the day so I tend to prefer light themes and I was very happy to see that the hyper-one-light theme was available.

I can honestly say, this is the nicest light terminal theme I ever used. Every single color is distinguishable and it looks great. This might sound silly but, this is a pretty big deal.

The Hyper window itself is super minimal too which I like. There is an option to add the standard Windows buttons min, resize, close if you want them, but I just use the hotkeys. Opening a new tab and getting to the point where you have a prompt to enter text only takes about 1 second which is pretty good. Opening a split pane is the same speed too. However it takes about 5 seconds to open a completely new terminal window.These benchmarks miss the point in my opinion. When I'm choosing a terminal emulator, beyond features, the one "performance" metric that I'm interested in is latency; nothing else really affects my workflow positively or negatively.

In the benchmarks I've seen of alacritty wrt latency[1][2], it doesn't come out so well. Rather, I get the impression Alacritty's values don't match your own values in a terminal emulator, and that's totally OK. Historically, input latency hasn't been considered a big pain point by most users. Fair enough. In general, a terminal emulator is for use by a human, and humans can't really process info at the throughput rate of other terminal emulators, much less the faster alacritty.

All that said, I'm glad to hear there's a plan on the latency front. It's not ideal, but one flow I end up using at some points is tmux-as-grep. Basically, something either gets dumped to terminal, and I use tmux's search.

So then, for a combo of reasons some good, some bad I cat files to terminal on occasion, and I use tmux's search to find something in it. The idea isn't that the I'm processing at the throughput rate of the emulator - it's more that a low throughput rate delays when I can start actually looking for something useful. I've never understood this mentality. Regarding tabs, macOS has native tab support more or less built-in to the windowing system—you can see this in action if you create a document-based app in Xcode—but your app has to be structured in such as a way as to opt into it.

Have you considered opting into this or would you consider it contrary to the project goals? The hardest part about supporting things like this on macOS is that they often require a lot of additional code or a certain design whereas on Linux, a lot of these features are provided by the window manager. I don't consider it contrary to the project's goals if it's something that can be done unobtrusively.

Given your description, it sounds like this may be something we could support easily. I filed to track this. Thanks for the suggestion!

This is actually enabled by default unless you disable it. No extra code needed, unless the macOS implementation conflicts with yours. Thanks for this clarification.

I don't see any reason we couldn't support this given that info. We haven't intentionally opted out of this that I know of, we just didn't start Alacritty from an XCode project on macOS. I've noticed you don't have anything in the menu bar. Thanks for this additional feedback. It sounds like we should create an XCode project from scratch to get many of the defaults and figure out how to bridge this with our current implementation. Has the input latency improved any?

I liked alacritty, but I switched to mlterm after a while because the input latency was really bugging me. Thanks for this feedback!
