## Disable/Enable

Uncheck/Check `View > Show Colors`

## Downloads

- https://github.com/junichi11/netbeans-color-codes-preview/releases

## Supported color patterns

- Hex color code (e.g. `#fff` `#000000`)
- Css rgb/rgba values (e.g. `rgb(0, 0, 0)`, `rgb(50%, 0%, 100%)`, `rgba(255,255,255, 0.8)`)
- Css hsl/hsla values (e.g. `hsl(0, 100%, 50%)`, `hsla(120, 100%, 50%, 0.5)`)
- Named colors (e.g. `red`, `blue`)
- Java Color class colors (e.g. `Color.black`, `new Color(100, 100, 100)`, `new Color(0, 0, 255, 255)`)

## Multiple colors

- Show top two colors in a sidebar if there are multiple colors in a line.
- If you want to check all colors, please click a specific rectangle. They will be shown as a list.

## Change a color using a color chooser

![changing-colors](https://raw.githubusercontent.com/junichi11/netbeans-color-codes-preview/master/images/netbeans-color-codes-preview-changing-colors.gif)

- Click a colored rectangle
- Click a color value of a list
- Select a new color in the color chooser
- An old color value will be changed to new one with the same format(Hex and CSS)

### NOTE

If "GTK look and feel" is used, an alpha value is not available. So, in that case, this plugin doesn't show the color chooser for `new Color(r, g, b, a)`.

## Generate color codes

You can generate color codes via a code generator(<kbd>Alt</kbd> + <kbd>Ins</kbd>).

1. Run a code generator(<kbd>Alt</kbd> + <kbd>Ins</kbd>)
2. Choose `Color...`
3. Choose the format you expect (e.g. `new Color(r, g, b)`)
4. Choose a color
5. Click the OK button
6. A color code is generated at the caret position

## Options

Tools > Options > Miscellaneous > Color Codes Preview

### Hex and CSS colors

![screenshot-options](https://raw.githubusercontent.com/junichi11/netbeans-color-codes-preview/master/images/netbeans-color-codes-preview-options.png)

#### Regex for enabled mime-types

Default value is `^text/(x-)?(css|less|sass|scss)$`.
If you would like to disable/enable some mime-types, please change the default regex.
This pattern is used when the plugin checks a mime-type.

#### Resolve Sass and Less Variables

This option is `false` by default. If you would like to resolve Sass and Less variables, please check it.

**NOTE:** The simplest cases only e.g. `$green: #0f0;`

#### Named Colors

This option is `false` by default. If you would like to show named colors, please check it.

### Java Color class colors

#### NOTE

If you would like to show colors of `Color.decode(<hex>)` e.g. `Color.decode("#000000")`, Please add `java` to "Regex for enabled mime-types" of Hex and CSS e.g. (`^text/(x-)?(css|less|sass|scss|java)$`)

## Contributing

### Bugs & New Features

If you have some requests, problems, and more, first of all, please submit them to [Issues](https://github.com/junichi11/netbeans-color-codes-preview/issues).
Please don't create PRs soon. I'll request creating PRs if I need your help.

### Typos

If you find typos or incorrect English, please let me know. If you would like to create a PR for fixing them, please do that.

## NOTE

- Colors may be shown if they are not color codes. e.g. "#feature" contains `#fea`. This plugin recognizes it as a hex color code.
- If you use the GTK Look and Feel, you cannot change an alpha value in the color chooser.
- Hsl or hsla color values may not be changed correctly when you use the color chooser. (There may be 1% errors.)
- Doesn't recognize the following Java Color case: `new Color(0.25f, 0.50f, 0);`, in such a case, please add `f`. i.e. `0f` or `1f`.
