# 🦐 Ebi: GitHub repositories contents search


Build Status

Searches files within GitHub repositories. It can be used as a command line tool or a library.

Ebi (えび) is [Japanese for prawn/shrimp](https://translate.google.com/#view=home&op=translate&sl=en&tl=ja&text=Prawn), and intends to be a small little tool to crawl through your sea of code on GitHub, finding you nuggets of information.

## Command Line Usage

### Global installation (recommmended)

`npm install --global ebi`

When you run the tool, it will automatically notify you if there is a newer version of it available for you to update to.

[You can disable notifications](https://www.npmjs.com/package/update-notifier#user-settings) if you'd prefer not to be notified about updates.

## No installation

`npx ebi`

The npx command lets you use this tool without installing it. However, each time you use npx it downloads the whole package from the npm registry, which takes a while. That's why global installation is reccommended.

> Note: If this tool is globally installed, npx ebi will use that globally installed version rather than downloading.

## Usage

1. [Set up a GitHub personal access token](#setting-up-your-github-personal-access-token) (with all `repo` scopes) assigned to the `GITHUB_PERSONAL_ACCESS_TOKEN` environment variable

2. Pass in the list of space-separated repositories as arguments:

ebi Financial-Times/ebi Financial-Times/tako

3. If ebi is silently failing you can turn on `--verbose` to see more logging

### Examples

Show help

ebi --help

Input the repositories to the ebi command either via `stdin` or `args`.
Determine whether a repo has a `Procfile`

```
$ echo -e "Financial-Times/ebi" | ebi contents Procfile
```

```
$ ebi contents Procfile Financial-Times/ebi
```

Find all the `node` engines and their versions in `package.json`

```
$ cat repositories.txt | ebi package:engines
```

For more examples see [Usage Examples](https://github.com/Financial-Times/ebi/wiki/Usage-Examples).

### JSON output

To output as JSON, you can use the `--json` flag eg, `ebi package:engines --json`.

The output format of the JSON is

```
{
type,
repository,
filepath,
fileContents,
[search],
[regex],
[error]
}
```

| Field | Values | Description |
| -------------- | -------------------------------- | ------------------------------------------------------------- |
| `type` | `match`, `no-match`, `error` | Type of result |
| `repository` | `Financial-Times/ebi` | The full repository path |
| `filepath` | `package.json` | The filepath searched for |
| `fileContents` | `{\n \"name\": \"ebi\",\n ... }` | The file contents serialized as a string |
| `search` | `name` | [optional] The search term |
| `regex` | `no.*` | [optional] The regex used for search (ie, `--regex`) |
| `error` | `404 ERROR: ...` | [optional] The error message if the result is of type `error` |

## Library Usage

To use `ebi` as a library in a NodeJS project:

npm install ebi

Require `ebi`, and run a search:

```javascript
const {
contentsSearch,
packageSearch,
packageEnginesSearch
} = require('ebi');

// Get a repository list
const repoList = [
'Financial-Times/ebi'
];

const { getResults, resultsAsync } = await contentsSearch({
filepath: 'package.json',
search, // Optional
token, // Optional
regex, // Optional
limit // Optional
})(repoList);

// Get results synchronously
const {
allResults,
searchMatches,
searchNoMatches,
searchErrors
} = await getResults();

// Get results asynchronously
const allAsyncResults = await Promise.all(
resultsAsync.map(promise => {
// Need to handle errors eg, if file is not found
return promise.catch(e => e);
})
);
```

Similarly:

```javascript
const { getResults, resultsAsync } = await packageSearch({
search: 'ebi', // Optional
token, // Optional
regex, // Optional
limit // Optional
})(repoList);
```

```javascript
const { getResults, resultsAsync } = await packageEnginesSearch({
search: 'node' // Optional
token, // Optional
regex, // Optional
limit // Optional
})(repoList);
```

See [JSDoc comments](./lib/ebi/ebi-results.js) for descriptions of the parameters. VS Code also has [JSDoc support in the editor](https://code.visualstudio.com/docs/languages/javascript#_jsdoc-support). To turn it on, either put `// @ts-check` on the top of a file or enable the `checkJS` compiler option.

See [examples](./examples) folder for more usage examples.

## Setting up your GitHub personal access token

This tool requires a [GitHub personal access token](https://help.github.com/articles/creating-a-personal-access-token-for-the-command-line/) with all `repo` scopes. This is _very powerful_ as it has access to modify a repository's settings, so it is strongly recommended that you store this token securely.

1. Create a [new GitHub personal access token with all `repo` scopes](https://github.com/settings/tokens/new?description=Ebi%20CLI&scopes=repo)
2. Store the token in the `GITHUB_PERSONAL_ACCESS_TOKEN` environment variable. You should avoid passing your GitHub personal access token directly to any CLI arguments as it will be visible in your shell history. There are a few options to do this:
1. If you work at Financial Times, you can follow the [GitHub personal access token docs](https://github.com/Financial-Times/next/wiki/How-to-store-and-access-a-GitHub-personal-access-token-securely)
2. Use your operating system's password management system (e.g. Keychain on macOS) to store and retrieve `GITHUB_PERSONAL_ACCESS_TOKEN` in your shell's rcfile (e.g. `~/.bashrc`), then restart your terminal
3. If all else fails, you can set it in your terminal with `GITHUB_PERSONAL_ACCESS_TOKEN=[github-token]`
4. If you want use a different token, you can pass in `--token=$GITHUB_PERSONAL_ACCESS_TOKEN` when you run the commands

## Development

1. Install [nvm](https://github.com/creationix/nvm) and use the correct node version

nvm use

1. Install dependencies

npm install

1. Run with:

./bin/ebi.js

### Testing

To run linting and tests

npm test

To just run linting

npm run lint

To fix linting issues

npm run lint-fix

To just run unit tests

npm run unit-test

To watch files and run unit tests

npm run unit-test:watch

To watch individual files and run unit tests

npm run unit-test:watch -- [file...]
# eg,
npm run unit-test:watch -- test/lib/get-repositories.test.js

### Code formatting with Prettier

This repo uses [prettier](https://prettier.io/) for code formatting. To make the most of this when working locally:

- Install the [`prettier-vscode`](https://marketplace.visualstudio.com/items?itemName=esbenp.prettier-vscode) extension in the extension side bar
- Update your settings to format files on save. This will check your file meets the prettier guidelines and will fix it each time you save. You can update the setting at `Code` --> `Preferences` --> `Settings` --> update `"editor.formatOnSave": true`

To make sure no `eslint` rules conflict with the prettier config, we have [eslint-config-prettier](https://github.com/prettier/eslint-config-prettier). This can be run with:

npm run eslint-check

### Publishing a release

CircleCI is set up to publish a release to `npm`. To release:

1. Create a [new release from GitHub](https://github.com/Financial-Times/ebi/releases/new)
1. Tag it with a [semver](https://semver.org/) range and a `v` prefix eg, `v1.2.3` or `v1.4.5-beta.3`
2. Create a title and description
3. Publish release
2. Wait for CircleCI to finish building the tag release, and once done, it will be appear at [npmjs.com/package/ebi](https://www.npmjs.com/package/ebi)
