# javadoc

Unopinionated, simple and powerful documentation generator.

## Installation

`$ npm i -g javadoc`

## Why?

This project was created to simplify the documentation of any code that accepts this kind of comments:

```js
/**
*
* Some description here. It accepts (optional) **markdown typing**.
*
* @some-property Some value in *markdown*
* @some-property Some value in *markdown*
* @some-other-property Some value in *markdown*
* @some-more-properties Some value in *markdown*
* The continuation of the value.
* It can take as much lines as you need.
* @and-more-properties
* @and-more
* @and-more...
*
*/
```

## Advantages

These are some of the advantages of this tool compared to other tools:

- **Language unopinionated**: it can be used in any programming language project, because:
- It uses regular expressions.
- It does not parse any source code.
- **Glob patterns**: it uses [glob patterns](https://www.npmjs.com/package/glob#glob-primer) to find files.
- **Unlimited Javadoc-like tags**: it uses the Javadoc styling but you are free to use any kind of tag, not only a limited set of them.
- **JSON or Markdown output**: it can extract Javadoc comments in:
- **JSON**: to abstractly program the views of your own project.
- **Markdown**: to directly use the comments in a typical *README.md* file, or similar.
- **CLI or API**: it has a command-line interface and an abstract programming interface, and both work almost the same way.

## CLI usage

As simple as:

```sh
$ javadoc
--include "**/*.js" "**/*.ts"
--exclude "**/node_modules/**" "**ignore**"
--format markdown
--output README.md
```

Or abbreviatedly:

```sh
$ javadoc
-i "**/*.php" "**/*.sql"
-e "**/node_modules/**" "**ignore**"
-f json
-o README.md
```

Type `javadoc --help` to see the help.

## API usage

```js
require("javadoc").generate({
include: ["**/*.js", "**/*.ts"],
exclude: ["**/node_modules/**"],
format: "markdown",
output: "README.md"
}).then(report => {
// manage a report of success and errors...
}).catch(error => {
// manage the error...
});
```

## API reference

Here you will find the whole API available for programmatic usage, documented.

*Note: the main interesting method is `Javadoc.generate`, which is the one called by the **CLI**.*

-----------------

### `Javadoc`

**Type**: *Class. Function.*

**Description**: Master class of the `javadoc` package.

-------------------

### `Javadoc.REGEX_PATTERNS`

**Type**: *Static property. Object.*

**Description**: Regular expression patterns used by the class.

-------------------------

### `Javadoc.DEFAULT_GLOB_OPTIONS`

**Type**: *Static property. Object.*

**Property**:

- `cwd`. Defaults to `process.cwd()`. Allowed options at [glob package](https://www.npmjs.com/package/glob#options)

- `dot`. Defaults to `true`. Allowed options at [glob package](https://www.npmjs.com/package/glob#options)

**Description**: Default options used by the `glob` package.

---------------------------

### `Javadoc.DEFAULT_OPTIONS`

**Type**: *Static property. Object.*

**Property**:

- `include:Array`. Defaults to `["**/*.js"]`. Allowed rules at [glob package](https://www.npmjs.com/package/glob).

- `exclude:Array`. Defaults to `["**/node_modules/**.js"]`. Allowed rules at [glob package](https://www.npmjs.com/package/glob).

- `format:String`. Defaults to `"markdown"`. Allowed values:
- `"md"`
- `"json"`

- `output:String`. Defaults to `undefined`. File into which dump the results. **Required value**.

**Description**: General options of the `Javadoc.generate` main method.

------------------------

### `Javadoc.findFiles`

**Type**: *Static method. Function.*

**Parameter**:

- `parameterIncludes:Array`. Replaces `DEFAULT_OPTIONS.include` as value.

- `parameterExcludes:Array`. Replaces `DEFAULT_OPTIONS.exclude` as value.

- `parameterOptions:Object`. Overrides `DEFAULT_GLOB_OPTIONS` as object.

**Returns**: files:Promise>. Asynchronously, returns an array of matched files (as Strings).

**Description**: Finds files based on glob patterns ([more info](https://www.npmjs.com/package/glob#usage)) included, excluded and glob options ([more info](https://www.npmjs.com/package/glob#options)).

-------------------------------

### `Javadoc.findCommentsInFile`

**Type**: *Static method. Function.*

**Parameter**: `file:String`. File into which look for the javadoc-comments.

**Returns**: `matches:Promise>`. Asynchronously, returns a list of matched javadoc-comments (as Objects) found in the passed file.

**Description**: From a file, it returns (asynchronously, by a Promise) javadoc-comments represented as Objects.

--------------------------------

### `Javadoc.findCommentsInString`

**Type**: *Static method. Function.*

**Parameter**: `text:String`. Text into which look for the javadoc-comments.

**Returns**: `totalMatches:Array`. List of javadoc-comments (as Objects) found in the passed String.

**Description**: Finds javadoc-comments (as Objects) from a String.

-----------------------------------

### `Javadoc.formatJsonToMarkdown`

**Type**: *Static method. Function.*

**Parameter**: `fileComments:Array`. List of javadoc-comments (as Object) to convert to markdown format.

**Returns**: `formatted:String`. Markdown code from passed javadoc-comments.

**Description**: Generates `markdown` code from a list of javadoc-comments.

-----------------------------------

### `Javadoc.generate`

**Type**: *Static method. Function.*

**Parameter**: `parameters:Object`. Overrides `Javadoc.DEFAULT_OPTIONS` as Object. To see more about properties, go to that static property of Javadoc class.

**Returns**: `output:Promise>`. Depending on `parameters.format` (`"json"`|`"markdown"`), it can return an Array or a String.

**Description**: Finds included files, dismisses excluded files, extracts javadoc-comments, formats them adecuately, and dumps the results into output file, while returning the output asynchronously (as a Promise).
