Base Docker image for the Repl.it evaluation server

Polygott

Warning: This repository is now obsolete. Replit is no longer developing Polygott and is fully betting on nix to expose tools and languages on Repls. This repository will still exist for archiving and historical purposes.

---

Overview

Replit.com allows you to quickly get started with any programming language online. In order to provide this capability, our evaluation server uses Docker with the buildx CLI plugin to ensure that all these languages are installed with the appropriate environment set up.

We previously used a separate Docker image for each language, but concluded that it was both simpler and more efficient to use a single image which contains all supported languages simultaneously. The code necessary to build this combined image, Polygott, resides in this repository. If you're lost and need some reference, we have a blog where we added elisp.

Because of the fact that building a monolithic image is unwieldy and takes too much time, the build itself is made of a directed graph of intermediate nodes, where each language is a node, and they all get stitched together at the end to build the final combined image.

Build and run

You can build either the entire image, a version that has a bundle of languages, and a version that is limited to a single language. The second one is used for CI, and the latter is recommended when you are adding or modifying support for a particular language, since building the entire image takes an extremely long time. Makefile targets are provided for each of these cases:

% make help
usage:
  make image         Build Docker image with all languages
  make image-ci      Build Docker image with all languages needed for CI
  make image-LANG    Build Docker image with single language LANG
  make run           Build and run image with all languages
  make run-LANG      Build and run image with single language LANG
  make test          Build and test all languages
  make test-LANG     Build and test single language LANG
  make changed-test  Build and test only changed/added languages
  make help          Show this message

As you can see, there is a facility for testing that languages have been installed and configured correctly. This involves running commands which are specified in the languages' configuration files, and checking that the output is as expected. To debug, you can also use the make run and make run-LANG targets to launch shells within the images.

You may want to bypass Docker's cache temporarily, for example to debug an intermittent network error while building one of the languages. To do this, identify the docker build command which is run by the Makefile, and run it yourself with the --no-cache flag.

The CI requires having up-to-date generated artifacts (the files in out/) committed to ensure a consistent Docker build environment. These will be refreshed by running the tests, or by running make -B build/stamps/out).

Language configuration

Each supported language has a TOML file in the languages subdirectory. The meaningful keys are as follows:

Mandatory

• entrypoint: The name of the file which will be executed on Replit.com when you press the Run button. This is used in the detect-language script built into the Polygott image: if a file exists with this name, then the project is detected to have this language. (Ties are resolved by popularity.) It is also used by the run-project script in order to identify the main file of the project.
• extensions: List of file extensions (use "py", not ".py") which files of this language may have. This is used in the detect-language script built into the Polygott image: if a file exists with one of these extensions, then the project is detected to have this language. (Ties are resolved by popularity.)
• name: The name of the language. The TOML file should then be named <name>.toml. This is also what you pass to the Makefile's image-LANG and test-LANG targets.

Optional

• aliases: List of strings indicating alternate names for the language, in addition to name. This is used to allow the run-language-server script to accept -l c++ in addition to -l cpp, among other things.
• aptKeys: List of PGP key IDs that must be passed to apt-key in order for the custom aptRepos configured to be trusted. For example, "09617FD37CC06B54".
• aptRepos: List of repository strings that must be passed to add-apt-repository in order for the custom packages configured to be available. For example, "deb https://dist.crystal-lang.org/apt crystal main".
• compile
  • command: The full command to compile the entrypoint file, as a list, including the filename. This is run before the run command.
• languageServer
  • command: Command to start an LSP language server, as a list. This is used in the run-language-server script built into the Polygott image.
• packages: List of additional Ubuntu packages to install for this language. (Packages which are required by all or many languages should be placed instead in packages.txt.) Check the Ubuntu Bionic package listing to see what your options are.
• popularity: Floating-point number indicating how popular the language is. Defaults to 2.0. This is used in the detect-language script built into the Polygott image: if a project is detected as more than one language, the winner is chosen by comparing popularity scores.
• run: Required, unless you provide no tests or you have asked to skip all of them.
  • command: The full command to run the entrypoint file, as a list, including the filename. It is run after the compile command, if one is provided. This is used to run tests.
• runtimeSetup: List of shell commands to be run by the polygott-lang-setup script built into the Polygott image.
• setup: List of shell commands to be run in phase 2 of the build process, as post-install steps.
• tests
  • TESTNAME
    • code: String to write to the entrypoint file before invoking the run command.
    • output: String expected to be written to stdout (not stderr) by running the code.
    • skip: Boolean, optional. If true, then the test is skipped. This allows you to easily "comment out" a test if there is something wrong with the infrastructure.
• versionCommand: A command to output the version of the language, as a list of strings. For example, ["kotlin", "-version"]. This is used in the polygott-survey command built into the Polygott image. (If versionCommand is omitted, some heuristics are used to guess it.)

Build process

• The language configuration files are validated against a JSON Schema specification located in schema.json.
• The .ejs files in the gen directory are transformed into shell scripts using the language configuration via the EJS templating system. This is done by a Node.js script inside the Docker image.
• The multi-stage Dockerfile is created from the language configuration files.
• Languages are installed in several phases. In phase 0, shared packages in packages.txt are installed, as well as APT keys and repositories are configured. In phase 1.0, apt-get update -y is run, which can be reused in later phases. In phase 1.5, language-specific packages are installed. In phase 2, language-specific setup commands are run.

Usage

Aside from all the language executables (python3, ruby, rust, etc.), there are several additional scripts available within the Docker image. They are documented below.

polygott-self-test

Run the tests defined in each language's configuration file, as in make test or make test-LANG. Always run all the tests, but if one of them fails, exit with a non-zero return code.

polygott-survey

Run the versionCommand specified for every language, and output the results in tabular format to stdout.

polygott-lang-setup [-l LANG]

Copy the contents of /opt/homes/LANG/ to /home/runner/, and run the runtimeSetup commands for it, if any were provided. LANG defaults to the output of detect-language.

detect-language

Try to identify the language used by the project in the current directory. This first checks if the entrypoint file exists for any language, and then checks if a file with any of the registered extensions exists for a language. If multiple languages match in either of those two phases, then the popularity of the two languages is used to resolve ties.

Output the language name to stdout if one is detected, otherwise do nothing.

run-project [-s] [-b] [-l LANG]

Execute the compile and run commands on the entrypoint file in the current directory. LANG defaults to the output of detect-language. If -s is passed, then the entrypoint file is written with the contents of stdin. If -b is passed, then some special logic is used instead of the compile and run commands; see the source for details.

run-language-server [-l LANG]

Run the languageServer command configured in the language's configuration file. LANG defaults to the output of detect-language.

Deployment

When a commit is merged to master, CircleCI automatically builds Polygott and pushes the image to Docker Hub. A Replit engineer has to then push the new Polygott to production.

Support for .NET Core runtime vs Mono

Adding support for .NET core SDK is fairly straightforward. Using the dotnet CLI allows modern project management and runtime. Currently, replit supports only mono runtime, which allows only compiling a file into an exe output.
Being able to use packages with C# is a basic requirement.
While it's also fairly straightforward to install dotnet separately, I believe this should be a core supported feature.

polygott-survey wrong for pascal

Returns:

pascal               Error: Illegal parameter: --version

I'm guessingpascal.toml is missing:

versionCommand = ["fpc", "-iV"]

Alternatively:

versionCommand = ["fpc", "-iW"]

The difference:

root@1834f17ee846:/home/runner# fpc -iV
3.0.4
root@1834f17ee846:/home/runner# fpc -iW
3.0.4+dfsg-18ubuntu2

[suggestion] Add an option set the command for a REPL

It would be cool if, in the TOML file for a language, there could be an option to specify the repl command (repl as in LISP repl rather than Repl.it repl). For example, Python could use something like:

[repl]
command = "python3"

Update Python to 3.10

add deno.land

https://deno.land/ is the new node.js (https://www.youtube.com/watch?v=puXyo1jGQys)
It already works with the current structure https://repl.it/@rafaelcastrocouto/deno-repl-tests
It would be very nice to have it in the languages list
I could work on this with a little help!

Inability to add package requests (for an example updating a package's src)

Yeah, can you make it possible for people to change packages addable within the IDE within this repo? Or how can I?

Polygott is now deprecated

Hello!

We announced a few months ago that we would be moving off of polygott and into nix in https://blog.replit.com/nix . As such, this repository will be mostly unmaintained and we will not be merging any pull requests (unless they are patching a security vulnerability).

Please reach out in Discord if you need any help with nix.

Add Lit Support

Lit is a fast-growing JavaScript library, would recommend adding.

detect language can be very slow

the detect-language script can take a while as find needs to walk the entire project directory structure many times. Projects with deps or other deep dirs end up taking a few seconds just to detect language.

README documentation for compile command is inaccurate

The readme documents the compile.command option as follows:

The full command to compile the entrypoint file, as a list, including the filename. This is run before the run command.

But examining several of the language configs under languages shows that "including the filename" is clearly not the case:

• polygott/languages/haskell.toml

  Lines 11 to 15 in e1e8094

  	command = [
  	"ghc",
  	"-o",
  	"main"
  	]

• polygott/languages/c.toml

  Lines 24 to 30 in e1e8094

  	command = [
  	"clang-7",
  	"-pthread",
  	"-lm",
  	"-o",
  	"main"
  	]

None of these command lists actually include the entrypoint source file, and trying to run those commands in the terminal gives an error like clang-7: error: no input files or ghc: no input files Usage: For basic information, try the --help' option.`

Image Build Fails on gapl language setup

When building the image the build scripts call undup(line) in phase2.ejs while installing each language.

undup is a function in index.js that seems to comment out commands in the install array if they are already in the dc array in index.js. It seems like this means commands from previously installed languages would still be in that array including previous make and make install?

This causes the make and make install commands to be commented out, and the apl binary to fail to be created and copied, causing a crash.

I was going to make a PR but I realized I don't really understand the point of the dup check in the first place so I thought I'd just comment.

Erlang/OTP 20 [erts-9.2] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:10] [kernel-poll:false]

Elixir <current version here> (compiled with Erlang/OTP 20)

Also, looks like none of the mix tasks work either. "mix help" errors out with: ** (Mix) The task "compile.all" could not be found

Advanced Port Mapping

Hey first of all thankyou folks working at repl.it for providing such a great product. Absolutely love it. I had one request in my mind. Can you please have advanced port mapping like for example right now every opened port gets proxied to port 80 of the url. Can it be something like we can have multiple ports opened running multiple servers. So for example server 1 can be on example.repl.com:9000 and other on example.repl.com:7000 . Thanks once again. Hope to get a reply soon.

Add Polygott to Replit as a language

Can you please add this to Replit as a language, so we can actually run stuff in Polygott?

Thanks in advance!

Also, 333^rd star!

Add README.md

A brief README on what this repo is and how to use it.

Add Haskell Language Server

HLS is the project collecting most of the manpower for Haskell IDE backend development. It supports LSP, and I saw that the README.md of this repository mentions LSP server, so I wrote this issue.
Is it possible to add HLS as a IDE backend of repl.it editor? If that's possible, it would be awesome.

When running run-project -b in a NodeJS project, the line 41: jq: command not found.

Seems to be missing in /packages.txt

can i host repl.it on my server ?

[rfc] speed up build times

The long build times for polygott seems to be a pretty universal issue. Specifically phase2 (the language installation step) must almost always run and takes by far the longest.

Proposed solutions:

• Build the base image (phase0 + phase1), an image for every language (phase2), then copy the relevant contents out of the the language images into a single unified image.
  • It's probably going to be tricky to define the relevant content and we'll to list that somewhere llike the toml.
• Build the base image (phase0 + phase1) followed by an image for every language (phase2) based on that base image.
  • This betrays a goal of polygott as every language is now isolated. We may want to choose a set of languages we deem important to be included in the base image.

What is this repl evaluation server?

typo in nextjs.toms

In https://github.com/replit/polygott/blob/master/languages/nextjs.toml#L9:

  "npm install -g [email protected]",
  "mkdir -p /hom/runner/pages",
  "yarn install"
]

Pretty sure it was meant to be: "mkdir -p /home/runner/pages", (hom/ => home/).

Add Powershell Support

Can you add Powershell support?

Question About Adding COBOL

Since COBOL requires access to the /usr/share/ folder, would it need more than just a TOML file?

Failing PR by python

`make test` doesn't use `polygott-lang-setup`

It seems that make test does not use polygott-lang-setup, shouldn't it?

Full context:

I'm working on Haxe language support, and I want to write a config file next to the entrypoint in the project directory. I tried to use

runtimeSetup = [
  "echo '--run Main' > /home/runner/run.hxml"
]

But it seems to have no effect when running make test-haxe.

[Java] Upgrade Language Server

Please, upgrade the language server Java is using.

The eclipse.jdt.ls version currently in use is 0.21, which is very very old.

It's so old that it doesn't even support Java 11 as Maven target.
(support was added in 0.26: https://github.com/eclipse/eclipse.jdt.ls/blob/master/CHANGELOG.md)

I suggest upgrading it to the latest version - 0.65, yet I'm not sure about all the breaking changes.

Ruby REPLs don't run with Bundler Context

By default, all Ruby REPLs run with the command ruby main.rb. This makes it impossible to run Ruby files with the context of Bundled Gems without explicitly setting run="bundler exec ruby main.rb" in the .replit file or running it in the Shell.

I don't know how package management works for Repl.it exactly, but this seems like some kind of oversight. If you were to do the standard gem installation method (i.e open the Interactive Package Manager in the IDE and search/add your gem) and then run your main Ruby file, any gems you might've installed straight up don't get included. The method described in the Repl.it blog (here) is also outdated and doesn't work either.

The most consistent fix I could come up with is bundler exec ruby main.rb, which allows the main Ruby file to be run with the context of gems you installed with bundle.

I'd love to open a PR and work on this if you guys are open to that. :P
