# ObsoHTML, the Obsolete HTML Checker

ObsoHTML is a Node.js script designed to scan HTML, PHP, JavaScript, and TypeScript files for obsolete or proprietary HTML attributes and elements (in scripts, it would catch JSX syntax). It helps you identify and update deprecated HTML code to be more sure to use web standards.

## Usage

### 1. As a Node Module

#### Installation

```console
npm i @j9t/obsohtml
```

(To install ObsoHTML globally, use the `-g` flag, as in `npm i -g @j9t/obsohtml`.)

#### Execution

The script accepts a folder path as a command line option, which can be specified in both short form (`-f`) and long form (`--folder`). The folder path can be either absolute or relative.

##### Example Commands

Use the default directory (user home directory):

```console
npx obsohtml
```

Specify a folder using an absolute path (easiest and most common use case):

```console
npx obsohtml -f /path/to/folder
```

Specify a folder using a relative path:

```console
npx obsohtml -f ../path/to/folder
```

### 2. As a Standalone Script

#### Installation

Download or fork [the source repository](https://github.com/j9t/obsohtml).

#### Execution

The script accepts a folder path as a command line option, which can be specified in both short form (`-f`) and long form (`--folder`). The folder path can be either absolute or relative.

##### Example Commands

(All commands as run from the root directory of the downloaded repository.)

Use the default directory (user home directory):

```console
node bin/obsohtml.js
```

Specify a folder using an absolute path (easiest and most common use case):

```console
node bin/obsohtml.js -f /path/to/folder
```

Specify a folder using a relative path:

```console
node bin/obsohtml.js -f ../path/to/folder
```

## Output

The script will output messages to the console indicating any obsolete attributes or elements found in the scanned files, along with the file paths where they were detected.

## Background

This started as an experiment, in which I used AI to produce this little HTML quality helper, its tests, and its documentation. While it’s pretty straightforward, I might have missed something.
