# @onlang-org/onst (onst)
> fetch JSON schema from [onst GitHub repository](https://github.com/onlang-org/onst) or [SchemaStore](https://www.schemastore.org). THe package exposes helper functions and also can be installed globally to be used via its interactive CLI built using [inquirer](https://www.npmjs.com/package/inquirer)

The package uses [onst-schemastore](https://www.npmjs.com/package/@onlang-org/onst-schemastore) to simplify fetching and categorising SchemaStore catalog into topics and download in bulk. (eg. download all schemata for AWS in one go). Read more about it [here](https://github.com/onlang-org/onst-schemastore). It leverages the GitHub [Octokit](https://github.com/octokit/octokit.js) API for working with schema files hosted on [onst github repository](https://github.com/onlang-org/onst).
onst provides a convenient CLI interface designed using [inquirer](https://www.npmjs.com/package/inquirer). You can fetch schema files, show the schema list, and generate example ONL (ONLang) files from the schema.

## Prerequisites
Before using the package, ensure you have the following set up:
- Node.js 14+ or higher [https://nodejs.org/en/]
- [npm](https://www.npmjs.com/)
## Installation
Install the package using npm:
```bash
npm install -g @onlang-org/onst
```
## Usage
**Show Help**
```
onst help
```
This command shows help information about the available commands and their usage.
**Show Version**
```
onst version
```
This command displays the version of the ONLang CLI.
**Fetch Schema Files**
```
onst fetch [-s]
-s, --schemastore: Use Schemastore.org (default is false).
```
This command fetches schema files from the onst GitHub repository for ONLang.
**Show Schema List**
```
onst show [-s]
-s, --schemastore: Use Schemastore.org (default is false).
```
This command shows the list of schemata available in the onst GitHub repository for ONLang.
**Generate Example ONL**
```
onst example [-s] [-w] [-r] [-e] [-f ] [-d ]
-s, --schemastore: Use Schemastore.org (default is false).
-w, --write: write the generated ONL files.
-r, --random: Use fake values for optional properties.
-e, --example: Use example values for required properties.
-f, --file : Specify the file name for the generated ONL file.
-d, --destination : Specify the destination path where the generated ONL will be saved.
```
This command generates ONL files from the schema.
### Examples
```
onst example -w -r -f example.onl -d ./output
```
This example generates an ONL file, uses random values for optional properties, writes the file with the name example.onl, and stores it in the ./output directory.
## Current Available Schemas
- Qualtrics
- [Survey](/schema/qualtrics.survey.d.json)
- [Dataset](/schema/qualtrics.dataset.d.json)
- [Contact](/schema/qualtrics.contact.d.json)
## Architecture
**GitHub Interaction**: Utilizes the GitHub API through the Octokit library for fetching repository content.
**User Interaction**: Employs the Inquirer library for interactive command-line prompts.
**File Operations**: Utilizes Node.js File System (fs) for reading, saving, and searching files.
**Configuration**: Relies on environment variables for GitHub credentials and repository details.
**Example Generation**: Generates example ONL files based on the schema and uses [json-schema-faker](https://github.com/json-schema-faker/json-schema-faker) and then transpiles it into ONL using [json-to-pretty-yaml](https://www.npmjs.com/package/json-to-pretty-yaml)
## Extending onst
onst by default gets the schema list from the onst GitHub repository. To fetch schema files from a different repository, usethe env variables `GITHUB_OWNER`, `GITHUB_PATH` and `GITHUB_REPO`.
- GITHUB_OWNER: The username of the repository to fetch schema files from.
- GITHUB_REPO: The name of the repository to fetch schema files from.
- GITHUB_PATH: The path within the repository to fetch schema files from.
### Examples
- [JSON](/examples/json)
- [ONL](/examples/onl)
