Tools for generating to and from wit format.
Option 1
cargo install witme
If generating json schemas need nodejs installed. One suggestion is to use nvm.
Option 2
npm i -g witme
Currently this repo is geared toward NEAR smart contracts (currently only for Rust), but the goal is to become a general purpose tool for working with the .wit
format.
.wit
from NEAR smart contracts written in Rust.wit
for interacting with contractsCurrently there is a near
subcommand for dealing with NEAR related transformations.
witme near wit
index.wit
file in the root of a rust project (note: it can't be a workspace). This builds on witgen.witme near ts
.wit
file (defaults index.wit
-> ./ts/*
). This builds on wit-bindgenwitme near json
./ts/index.ts
--> index.schema.json
), which uses ts-json-schema-generator.witme near inject
The generated json schema can be used to automatically generate a react form which can validate the arguments to a contract call. Since .wit
has a notion of documentation comments the documentation provided by the Rust source will be available in the generated TS and Json schema. This also allows special annotations which can add more conditions on the types used in the contract.
For example,
/// @minLength 2
/// @maxLength 64
/// @pattern ^(([a-z\d]+[-_])*[a-z\d]+\.)*([a-z\d]+[-_])*[a-z\d]+$
type AccountId = String
Generates the following wit:
/// @minLength 2
/// @maxLength 64
/// @pattern ^(([a-z\d]+[-_])*[a-z\d]+\.)*([a-z\d]+[-_])*[a-z\d]+$
type account-id = string
which generates the following typescript:
/**
* @minLength 2
* @maxLength 64
* @pattern ^(([a-z\d]+[-_])*[a-z\d]+\.)*([a-z\d]+[-_])*[a-z\d]+$
*/
export declare type AccountId = string;
which generates the following json schema:
{
"$schema": "http://json-schema.org/draft-07/schema#",
"definitions": {
"AccountId": {
"maxLength": 64,
"minLength": 2,
"pattern": "^(([a-z\\d]+[-_])*[a-z\\d]+\\.)*([a-z\\d]+[-_])*[a-z\\d]+$",
"type": "string"
},
Consider the rust-status-message
example in this repo:
/// Retreive a message for a given account id
pub fn get_status(&self, account_id: AccountId) -> Option<String> {
self.records.get(&account_id)
}
generates the following schema for its arguments:
{
"GetStatus": {
"additionalProperties": false,
"contractMethod": "view",
"description": "Retreive a message for a given account id",
"properties": {
"account_id": {
"$ref": "#/definitions/AccountId"
}
},
"required": [
"account_id"
],
"type": "object"
},
}
And the following TS method on the generated Contract
class:
/**
* Retreive a message for a given account id
*/
get_status(args: {
account_id: AccountId;
}, options?: ViewFunctionOptions): Promise<string | null>;
See close-up for an example for generating forms from a schema.
Currently .wit
doesn't prescribe how variant types are implemented for a language. witme
currently supports JSON encoded arguments and return values. Thus variants are currently encoded the same as the defaults provided by serde_json. However, in the future borsh support would remove this restriction and allow variant types to be encoded more efficiently.

Serde
*Serde is a framework for serializing and deserializing Rust data structures efficiently and generically.*
You may be looking for:
#[derive(Serialize, Deserialize)]
Click to show Cargo.toml. Run this code in the playground.
[dependencies]
# The core APIs, including the Serialize and Deserialize traits. Always
# required when using Serde. The "derive" feature is only required when
# using #[derive(Serialize, Deserialize)] to make Serde work with structs
# and enums defined in your crate.
serde = { version = "1.0", features = ["derive"] }
# Each data format lives in its own crate; the sample code below uses JSON
# but you may be using a different one.
serde_json = "1.0"
use serde::{Serialize, Deserialize};
#[derive(Serialize, Deserialize, Debug)]
struct Point {
x: i32,
y: i32,
}
fn main() {
let point = Point { x: 1, y: 2 };
// Convert the Point to a JSON string.
let serialized = serde_json::to_string(&point).unwrap();
// Prints serialized = {"x":1,"y":2}
println!("serialized = {}", serialized);
// Convert the JSON string back to a Point.
let deserialized: Point = serde_json::from_str(&serialized).unwrap();
// Prints deserialized = Point { x: 1, y: 2 }
println!("deserialized = {:?}", deserialized);
}
Serde is one of the most widely used Rust libraries so any place that Rustaceans congregate will be able to help you out. For chat, consider trying the #rust-questions or #rust-beginners channels of the unofficial community Discord (invite: https://discord.gg/rust-lang-community), the #rust-usage or #beginners channels of the official Rust Project Discord (invite: https://discord.gg/rust-lang), or the #general stream in Zulip. For asynchronous, consider the [rust] tag on StackOverflow, the /r/rust subreddit which has a pinned weekly easy questions post, or the Rust Discourse forum. It's acceptable to file a support issue in this repo but they tend not to get as many eyes as any of the above and may get closed without a response after some time.

Calyx provides a simple API for generating text with declarative recursive grammars.
gem install calyx
gem 'calyx'
The best way to get started quickly is to install the gem and run the examples locally.
Requires Roda and Rack to be available.
gem install roda
Demonstrates how to use Calyx to construct SVG graphics. Any Gradient generates a rectangle with a linear gradient of random colours.
Run as a web server and preview the output in a browser (http://localhost:9292
):
ruby examples/any_gradient.rb
Or generate SVG files via a command line pipe:
ruby examples/any_gradient > gradient1.xml
Requires the Twitter client gem and API access configured for a specific Twitter handle.
gem install twitter
Demonstrates how to use Calyx to make a minimal Twitter bot that periodically posts unique tweets. See @tiny_woodland on Twitter and the writeup here.
TWITTER_CONSUMER_KEY=XXX-XXX
TWITTER_CONSUMER_SECRET=XXX-XXX
TWITTER_ACCESS_TOKEN=XXX-XXX
TWITTER_CONSUMER_SECRET=XXX-XXX
ruby examples/tiny_woodland_bot.rb
Faker is a popular library for generating fake names and associated sample data like internet addresses, company names and locations.
This example demonstrates how to use Calyx to reproduce the same functionality using custom lists defined in a YAML configuration file.
ruby examples/faker.rb
Require the library and inherit from Calyx::Grammar
to construct a set of rules to generate a text.
require 'calyx'
class HelloWorld < Calyx::Grammar
start 'Hello world.'
end
To generate the text itself, initialize the object and call the generate
method.
hello = HelloWorld.new
hello.generate
# > "Hello world."
Obviously, this hardcoded sentence isn’t very interesting by itself. Possible variations can be added to the text by adding additional rules which provide a named set of text strings. The rule delimiter syntax ({}
) can be used to substitute the generated content of other rules.
class HelloWorld < Calyx::Grammar
start '{greeting} world.'
greeting 'Hello', 'Hi', 'Hey', 'Yo'
end
Each time #generate
runs, it evaluates the tree and randomly selects variations of rules to construct a resulting string.
hello = HelloWorld.new
hello.generate
# > "Hi world."
hello.generate
# > "Hello world."
hello.generate
# > "Yo world."
By convention, the start
rule specifies the default starting point for generating the final text. You can start from any other named rule by passing it explicitly to the generate method.
class HelloWorld < Calyx::Grammar
hello 'Hello world.'
end
hello = HelloWorld.new
hello.generate(:hello)
As an alternative to subclassing, you can also construct rules unique to an instance by passing a block when initializing the class:
hello = Calyx::Grammar.new do
start '{greeting} world.'
greeting 'Hello', 'Hi', 'Hey', 'Yo'
end
hello.generate
Basic rule substitution uses single curly brackets as delimiters for template expressions:
fruit = Calyx::Grammar.new do
start '{colour} {fruit}'
colour 'red', 'green', 'yellow'
fruit 'apple', 'pear', 'tomato'
end
6.times { fruit.generate }
# => "yellow pear"
# => "red apple"
# => "green tomato"
# => "red pear"
# => "yellow tomato"
# => "green apple"
Rules are recursive. They can be arbitrarily nested and connected to generate larger and more complex texts.
class HelloWorld < Calyx::Grammar
start '{greeting} {world_phrase}.'
greeting 'Hello', 'Hi', 'Hey', 'Yo'
world_phrase '{happy_adj} world', '{sad_adj} world', 'world'
happy_adj 'wonderful', 'amazing', 'bright', 'beautiful'
sad_adj 'cruel', 'miserable'
end
Nesting and hierarchy can be manipulated to balance consistency with novelty. The exact same word atoms can be combined in a variety of ways to produce strikingly different resulting texts.
module HelloWorld
class Sentiment < Calyx::Grammar
start '{happy_phrase}', '{sad_phrase}'
happy_phrase '{happy_greeting} {happy_adj} world.'
happy_greeting 'Hello', 'Hi', 'Hey', 'Yo'
happy_adj 'wonderful', 'amazing', 'bright', 'beautiful'
sad_phrase '{sad_greeting} {sad_adj} world.'
sad_greeting 'Goodbye', 'So long', 'Farewell'
sad_adj 'cruel', 'miserable'
end
class Mixed < Calyx::Grammar
start '{greeting} {adj} world.'
greeting 'Hello', 'Hi', 'Hey', 'Yo', 'Goodbye', 'So long', 'Farewell'
adj 'wonderful', 'amazing', 'bright', 'beautiful', 'cruel', 'miserable'
end
end
By default, the outcomes of generated rules are selected with Ruby’s built-in pseudorandom number generator (as seen in methods like Kernel.rand
and Array.sample
). To seed the random number generator, pass in an integer seed value as the first argument to the constructor:
grammar = Calyx::Grammar.new(seed: 12345) do
# rules...
end
Alternatively, you can pass a preconfigured instance of Ruby’s stdlib Random
class:
random = Random.new(12345)
grammar = Calyx::Grammar.new(rng: random) do
# rules...
end
When a random seed isn’t supplied, Time.new.to_i
is used as the default seed, which makes each run of the generator relatively unique.
Choices can be weighted so that some rules have a greater probability of expanding than others.
Weights are defined by passing a hash instead of a list of rules where the keys are strings or symbols representing the grammar rules and the values are weights.
Weights can be represented as floats, integers or ranges.
The following definitions produce an equivalent weighting of choices:
Calyx::Grammar.new do
start 'heads' => 1, 'tails' => 1
end
Calyx::Grammar.new do
start 'heads' => 0.5, 'tails' => 0.5
end
Calyx::Grammar.new do
start 'heads' => 1..5, 'tails' => 6..10
end
Calyx::Grammar.new do
start 'heads' => 50, 'tails' => 50
end
There’s a lot of interesting things you can do with this. For example, you can model the triangular distribution produced by rolling 2d6:
Calyx::Grammar.new do
start(
'2' => 1,
'3' => 2,
'4' => 3,
'5' => 4,
'6' => 5,
'7' => 6,
'8' => 5,
'9' => 4,
'10' => 3,
'11' => 2,
'12' => 1
)
end
Or reproduce Gary Gygax’s famous generation table from the original Dungeon Master’s Guide (page 171):
Calyx::Grammar.new do
start(
:empty => 0.6,
:monster => 0.1,
:monster_treasure => 0.15,
:special => 0.05,
:trick_trap => 0.05,
:treasure => 0.05
)
empty 'Empty'
monster 'Monster Only'
monster_treasure 'Monster and Treasure'
special 'Special'
trick_trap 'Trick/Trap.'
treasure 'Treasure'
end
Dot-notation is supported in template expressions, allowing you to call any available method on the String
object returned from a rule. Formatting methods can be chained arbitrarily and will execute in the same way as they would in native Ruby code.
greeting = Calyx::Grammar.new do
start '{hello.capitalize} there.', 'Why, {hello} there.'
hello 'hello', 'hi'
end
4.times { greeting.generate }
# => "Hello there."
# => "Hi there."
# => "Why, hello there."
# => "Why, hi there."
You can also extend the grammar with custom modifiers that provide useful formatting functions.
Filters accept an input string and return the transformed output:
greeting = Calyx::Grammar.new do
filter :shoutycaps do |input|
input.upcase
end
start '{hello.shoutycaps} there.', 'Why, {hello.shoutycaps} there.'
hello 'hello', 'hi'
end
4.times { greeting.generate }
# => "HELLO there."
# => "HI there."
# => "Why, HELLO there."
# => "Why, HI there."
The mapping shortcut allows you to specify a map of regex patterns pointing to their resulting substitution strings:
green_bottle = Calyx::Grammar.new do
mapping :pluralize, /(.+)/ => '\\1s'
start 'One green {bottle}.', 'Two green {bottle.pluralize}.'
bottle 'bottle'
end
2.times { green_bottle.generate }
# => "One green bottle."
# => "Two green bottles."
In order to use more intricate rewriting and formatting methods in a modifier chain, you can add methods to a module and embed it in a grammar using the modifier
classmethod.
Modifier methods accept a single argument representing the input string from the previous step in the expression chain and must return a string, representing the modified output.
module FullStop
def full_stop(input)
input << '.'
end
end
hello = Calyx::Grammar.new do
modifier FullStop
start '{hello.capitalize.full_stop}'
hello 'hello'
end
hello.generate
# => "Hello."
To share custom modifiers across multiple grammars, you can include the module in Calyx::Modifiers
. This will make the methods available to all subsequent instances:
module FullStop
def full_stop(input)
input << '.'
end
end
class Calyx::Modifiers
include FullStop
end
Alternatively, you can combine methods from existing Gems that monkeypatch String
:
require 'indefinite_article'
module FullStop
def full_stop
self << '.'
end
end
class String
include FullStop
end
noun_articles = Calyx::Grammar.new do
start '{fruit.with_indefinite_article.capitalize.full_stop}'
fruit 'apple', 'orange', 'banana', 'pear'
end
4.times { noun_articles.generate }
# => "An apple."
# => "An orange."
# => "A banana."
# => "A pear."
Rule expansions can be ‘memoized’ so that multiple references to the same rule return the same value. This is useful for picking a noun from a list and reusing it in multiple places within a text.
The @
sigil is used to mark memoized rules. This evaluates the rule and stores it in memory the first time it’s referenced. All subsequent references to the memoized rule use the same stored value.
# Without memoization
grammar = Calyx::Grammar.new do
start '{name} <{name.downcase}>'
name 'Daenerys', 'Tyrion', 'Jon'
end
3.times { grammar.generate }
# => Daenerys <jon>
# => Tyrion <daenerys>
# => Jon <tyrion>
# With memoization
grammar = Calyx::Grammar.new do
start '{@name} <{@name.downcase}>'
name 'Daenerys', 'Tyrion', 'Jon'
end
3.times { grammar.generate }
# => Tyrion <tyrion>
# => Daenerys <daenerys>
# => Jon <jon>
Note that the memoization symbol can only be used on the right hand side of a production rule.
Rule expansions can be marked as ‘unique’, meaning that multiple references to the same rule always return a different value. This is useful for situations where the same result appearing twice would appear awkward and messy.
Unique rules are marked by the $
sigil.
grammar = Calyx::Grammar.new do
start "{$medal}, {$medal}, {$medal}"
medal 'Gold', 'Silver', 'Bronze'
end
grammar.generate
# => Silver, Bronze, Gold
Template expansions can be dynamically constructed at runtime by passing a context map of rules to the #generate
method:
class AppGreeting < Calyx::Grammar
start 'Hi {username}!', 'Welcome back {username}...', 'Hola {username}'
end
context = {
username: UserModel.username
}
greeting = AppGreeting.new
greeting.generate(context)
In addition to defining grammars in pure Ruby, you can load them from external JSON and YAML files:
hello = Calyx::Grammar.load('hello.yml')
hello.generate
The format requires a flat map with keys representing the left-hand side named symbols and the values representing the right hand side substitution rules.
In JSON:
{
"start": "{greeting} world.",
"greeting": ["Hello", "Hi", "Hey", "Yo"]
}
In YAML:
---
start: "{greeting} world."
greeting:
- Hello
- Hi
- Hey
- Yo
Calling #evaluate
on the grammar instance will give you access to the raw generated tree structure before it gets flattened into a string.
The tree is encoded as an array of nested arrays, with the leading symbols labeling the choices and rules selected, and the trailing terminal leaves encoding string values.
This may not make a lot of sense unless you’re familiar with the concept of s-expressions. It’s a fairly speculative feature at this stage, but it leads to some interesting possibilities.
grammar = Calyx::Grammar.new do
start 'Riddle me ree.'
end
grammar.evaluate
# => [:start, [:choice, [:concat, [[:atom, "Riddle me ree."]]]]]
