Gutter Color

Gutter Color is a cross-platform Sublime Text plugin which displays a colored icon for all lines which contain a color.

Requirements

ImageMagick

Configure

Install ImageMagick
Set the convert_path in Preferences: Package Settings > GutterColor > Settings – User to the location of the ImageMagick convert script:

{
  "convert_path" : "/usr/local/bin/convert"
}

Additional user settings:
- supported_syntax sets the filetypes the script runs in.
- use_transparency determines whether to draw RGBA, HSLA, and custom formats with alpha channels enabled, compositing the fill color over a checkered gray background. Setting this to "light" is the same as true, but uses a lighter checkerboard.
- custom_colors adds additional regexes for custom color string formats, along with associated string matching and affixing rules. (See default settings file.)
- fix_color_schemes enables automatic editing of the current tmTheme to correct ST's icon tinting. (See Icon Tinting and Light Color Schemes below.)

Troubleshooting

Fixing ImageMagick on OSX

If you're experiencing issues with ImageMagick (installed via brew) when using GutterColor on OSX, follow these instructions to fix it.

Uninstall IM with brew uninstall imagemagick
Install again with a couple of options brew install imagemagick --with-xz --with-font-config --with-little-cms --with-little-cms2
Check the location of convert with type convert
Copy the location and edit the GutterColor/Settings - User convert_path to be the value of step 3.

Icon Tinting and Light Color Schemes

Sublime Text automatically tints gutter icons to match your background color settings. Unfortunately this can cause Gutter Color's samples to vary from slightly inaccurate to completely black. To counteract this effect, Gutter Color can generate a new copy of your current color scheme that sets the background to black only for the scope of the plugin. You will not see any visual changes other than the icons.

To manually update a color scheme, open the Command Palette and select GutterColor: Fix Current Color Scheme.
Alternatively, the plugin can run this process automatically via the setting fix_color_schemes.

Other Display Issues

Sublime's placeholder image is a red-and-yellow-striped box. If you are seeing these, it is most likely that Gutter Color cannot find ImageMagick to generate the samples. Double-check that you have your convert_path setting and/or your PATH environment variable set correctly, and restart Sublime Text. If the problem persists, feel free to contact us.
