Configuring a Repl

Every new repl comes with a .replit and a replit.nix file that let you configure your repl to do just about anything in any language!

In most repls, these files are hidden by default. But you can find them easily by clicking the three dot menu in the file tree, and selecting Show hidden files.

Showing the .replit file

replit.nix

Every new repl is now a Nix repl, which means you can install any package available on Nix, and support any number of languages in a single repl. You can search for a list of available packages here.

The replit.nix file should look something like the example below. The deps array specifies which Nix packages you would like to be available in your environment.

{ pkgs }: {
deps = [
pkgs.cowsay
];
}

.replit

The .replit file allows you to configure many options for your repl, most basic of which is the run command.

Check out how the repl below is using .replit to print "hello world" instead of running the code:

Here's a video on how to use both the .replit file and the replit.nix file to run multiple languages in a repl as well as a video game.


.replit files follow the toml configuration format and look something like this:

# The command that is executed when the run button is clicked.
run = ["cargo", "run"]

# The default file opened in the editor.
entrypoint = "src/main.rs"

# Setting environment variables
[env]
FOO="foo"

# Packager configuration for the Universal Package Manager
# See https://github.com/replit/upm for supported languages.
[packager]
language = "rust"

[packager.features]
# Enables the package search sidebar
packageSearch = true
# Enabled package guessing
guessImports = false

# Per language configuration: language.<lang name>
[languages.rust]
# The glob pattern to match files for this programming language
pattern = "**/*.rs"

# LSP configuration for code intelligence
[languages.rust.languageServer]
start = ["rust-analyzer"]

In the code above, the strings in the array assigned to run are executed in order in the shell whenever you hit the "Run" button.

The language configuration option helps the IDE understand how to provide features like packaging and code intelligence.

And the [languages.rust] pattern option is configured so that all files ending with .rs are treated as Rust files. The name is user-defined and doesn't have any special meaning, we could have used [languages.rs] instead.

We can now set up a language server specifically for Rust. Which is what we do with the next configuration option: [languages.rust.languageServer]. Language servers add smart features to your editor like code intelligence, go-to-definition, and documentation on hover.

Since repls are fully configurable, you're not limited to just one language. For example, you could install Clojure and its language server using replit.nix, add a [languages.clojure] configuration option to the above .replit file that matched all Clojure files and have code intelligence enabled for both languages in the same repl.

.replit reference

A Command can either be a string or a list of strings. If the Command is a string ("node index.js"), it will be executed via sh -c "<Command>". If the Command is a list of strings (["node", "index.js"]), it will be directly executed with the list of strings passed as arguments. When possible, it is preferred to pass a list of strings.


run

Type: Command

The command to run the repl. It has lower precedence than the [interpreter] command (i.e. if [interpreter] command is set, it will run instead of the run command).


entrypoint

Type: string

The name of the main file including the extension. This is the file that will be run, and shown by default when opening the editor.


onBoot

Type: Command

The command that executes after your repl has booted.


compile

Type: Command

The shell command to compile the repl before the run command. Only for compiled languages like C, C++, and Java.


audio

Type: boolean

Enables system-wide audio for the repl when configured to true.


language

Type: string

During a GitHub import, this tells the workspace which language should be used when creating the repl. For new repls, this option will always be Nix, so this field should generally not be touched.


hidden

Type: [string]

A list of files or folders to hide by default in the side filetree. These filepaths are still accessible through clicking the three dot menu in the file tree, and selecting Show hidden files.


[env]

Set environment variables. Don't put secrets here—use the Secrets tab in the left sidebar.

Example:

[env]
VIRTUAL_ENV = "/home/runner/${REPL_SLUG}/venv"
PATH = "${VIRTUAL_ENV}/bin"
PYTHONPATH="${VIRTUAL_ENV}/lib/python3.8/site-packages"

interpreter

Specifies the interpreter, which should be a compliant prybar binary.

command

Type: [string]

This is the command that will be run to start the interpreter. It has higher precedence than the run command (i.e. interpreter command will run instead of the run command).

prompt

Type: [byte]

This is the prompt used to detect running state, if unspecified it defaults to [0xEE, 0xA7].


[unitTest]

Enables unit testing to the repl.

language

Type: string

The language you want the unit tests to run. Supported strings: java, python, and nodejs.


[packager]

Description: Package management configuration. Learn more about installing packages here.

afterInstall

Type: Command

The command that is executed after a new package is installed.

ignoredPaths

Type: [string]

List of paths to ignore while attempting to guess packages.

ignoredPackages

Type: [string]

List of modules to never attempt to guess a package for, when installing packages.

language

Type: string

Specifies the language to use for package operations. See available languages in the Universal Package Manager repository.

[packager.features]

UPM features that are supported by the specified languages.

packageSearch

Type: Boolean

When set to true, enables a package search panel in the sidebar.

guessImports

Type: Boolean

When set to true, UPM will attempt to guess which packages need to be installed prior to running the repl.

enabledForHosting

Type: Boolean

Sets whether hosting the Repl requires running the packager before the Repl.


[languages.<language name>]

Per-language configuration. The language name has no special meaning other than to allow multiple languages to be configured at once.

pattern

Type: string

A glob used to identify which files belong to this language configuration (**/*.js)

[languages.<language name>.languageServer]

Configuration for setting up LSP for this language. This allows for code intelligence (autocomplete, underlined errors, etc...).

start

Type: Command

The command used to start the LSP server for the specified language.


[[hints]]

Type: {RegEx, string}

Set hints to display in the Shell alongside your output. You can have any number of hints in a Repl.

Each hint is made up of a regex and a message. The regex is a regular expression that searches through your output. If a match is found, the message is printed to the Shell.

Example:

[[hints]]
regex = "ERROR"
message = "Something went wrong."

[[hints]]
regex = "exit status [12]"
message = "Bad exit code, an error occurred."

[nix]

Where you specify a Nix channel.

channel

Type: string

A nix channel id.


[debugger]

Configures the debugger panel. See the advanced examples below for reference configurations.

See field types and docstrings

These are the Go types our backend uses to configure the debugger.

// DebuggerConfig holds information necesary to run a language's debugger,
// potentially through a debug adapter that follows the
// https://microsoft.github.io/debug-adapter-protocol/
type DebuggerConfig struct {
// Support indicates whether this debugger is supported by debugproxy.
Support bool `json:"support,omitempty" toml:"support"`

// If specified, then this overrides the main Compile config.
Compile *CompileConfig `json:"compile,omitempty" toml:"compile"`

// DAPConfig (see below) is the configuration needed for interactive
// debugging through an adapter that implements the DAP.
Interactive *DAPConfig `json:"interactive,omitempty" toml:"interactive"`

// TimeTravel is the configuration needed for time-travel debugging through
// an adapter that implements the DAP.
TimeTravel *struct {
// Record is the command needed to run and record an execution.
Record Command `json:"record" toml:"record"`

// Debug is the configuration of a DAP-compliant adapter that can be
// invoked to replay a pre-recorded execution.
Debug DAPConfig `json:"debug" toml:"debug"`
} `json:"timeTravel,omitempty" toml:"timeTravel"`

// ⚠️ Below are legacy options, prefer to use the `Interactive` field instead.

// DAPTransport indicates how the adapter exposes the DAP communication
// channel to the debugproxy. Valid values are "stdio" and something that Go
// accepts as an argument to `net.Dial()`.
DAPTransport string `json:"dapTransport,omitempty" toml:"dapTransport"`

// DAPConnectTimeout is the number of seconds that the debugproxy will wait
// for the port to be available before declaring the initialization failed.
// Defaults to 15s.
DAPConnectTimeout int64 `json:"dapConnectTimeout,omitempty" toml:"dapConnectTimeout"`

// DAPIntegratedAdapter indicates that the runtime environment that runs the
// debugee is the same one that runs the adapter. This means that the TTY
// should be attached to the runtime, and the DAP will be eposed through a
// separate channel.
DAPIntegratedAdapter *DAPIntegratedAdapterConfig `json:"dapIntegratedAdapter,omitempty" toml:"dapIntegratedAdapter"`

// DAPStartCommand is the shell command needed to start the debug adapter.
// Used as is.
DAPStartCommand *Command `json:"dapStartCommand,omitempty" toml:"dapStartCommand"`

// DAPInitializeMessage is the initialize message for the Debug Adapter
// Protocol. Sent as-is.
DAPInitializeMessage map[string]interface{} `json:"dapInitializeMessage,omitempty" toml:"dapInitializeMessage"`

// DAPLaunchMessage is the launch/attach message for the Debug Adapter
// Protocol. Sent as-is.
DAPLaunchMessage map[string]interface{} `json:"dapLaunchMessage,omitempty" toml:"dapLaunchMessage"`
}

// DAPConfig holds the information necessary to run a language's debugger through
// the a debug adapter that follows the
// https://microsoft.github.io/debug-adapter-protocol/
type DAPConfig struct {
// Transport indicates how the adapter exposes the DAP communication
// channel to the debugproxy. Valid values are "stdio" and something that Go
// accepts as an argument to `net.Dial()`.
Transport string `json:"transport" toml:"transport"`

// ConnectTimeout is the number of seconds that the debugproxy will wait
// for the port to be available before declaring the initialization failed.
// Defaults to 15s.
ConnectTimeout int64 `json:"connectTimeout,omitempty" toml:"connectTimeout"`

// IntegratedAdapter indicates that the runtime environment that runs the
// debugee is the same one that runs the adapter. This means that the TTY
// should be attached to the runtime, and the DAP will be eposed through a
// separate channel.
IntegratedAdapter *DAPIntegratedAdapterConfig `json:"integratedAdapter,omitempty" toml:"integratedAdapter"`

// StartCommand is the shell command needed to start the debug adapter.
// Used as is.
StartCommand Command `json:"startCommand,omitempty" toml:"startCommand"`

// InitializeMessage is the initialize message for the Debug Adapter
// Protocol. Sent as-is.
InitializeMessage map[string]interface{} `json:"initializeMessage,omitempty" toml:"initializeMessage"`

// LaunchMessage is the launch/attach message for the Debug Adapter
// Protocol. Sent as-is.
LaunchMessage map[string]interface{} `json:"launchMessage,omitempty" toml:"launchMessage"`
}

[[ports]]

Type: {localPort, externalPort}

The ports configuration section allows publicly exposing multiple HTTP web servers at the same time. By default any web server that starts listening on any port on 0.0.0.0 will be exposed at https://<repl name>.<username>.repl.co/, but you may want to expose additional, auxilarily servers. For example, some web frameworks use an extra server for handling hot reloading.

An extra server can be exposed by adding a new [[ports]] entry to your .replit file. You must specify a localPort and externalPort. The localPort is the port that your server is listening on inside the repl. The externalPort is the port that can be used to access the server publicly at https://<repl name>.<username>.repl.co:<external port>.

Currently only ports 5900, 8099, 9000 are allowed as the externalPort. Please contact support if you would like additional ports to be added.

Example:

[[ports]]
localPort = 4000
externalPort = 8099

[[ports]]
localPort = 9000
externalPort = 9000
