Highlights the current line in the editor; really simple.

You can now also underline the the current lines thanks to @sniperbat. This isn't enabled by default, and you can edit the colour and type of line.

When selecting more than one line of text, you can enable selection borders at the top and bottom of the selections. This isn't enabled by default. Courtesy of @djak250

You can now toggle the highlighted line by: cmd+alt+H You can now toggle the hiding the highlight on selecting text by: cmd+shift+alt+H

You can now toggle the underline by: cmd+alt+U You can now toggle the selection borders by: cmd+shift+alt+U

I've moved this package to use the new decorations API and as such we can no longer set arbitrary style on the lines. So, this means no more entering colours/ opacity in the settings.

You can update the colours by either updating the line-colors.less file once you've installed the package. Or by adding the following to your syle.less

I don't use the .cursor-line class as when you make selection on the same line, you then lose the highlight.

atom-text-editor::shadow {
  // The cursor line important to use rgba for opacity, also requires !important
  // to override any theme.
  .line.highlight-line {
    background: rgba(255, 0, 0, 0.3) !important;
  }

  // Replace 'solid', with 'dashed' or 'dotted' depending of what you have
  // set in the settings page.

  // This is for the bottom line (underline)
  .line.highlight-line-multi-line-solid-bottom {
    border-bottom-color: red;
  }

  // This is for the top line when you have the selection borders enabled.
  .line.highlight-line-multi-line-solid-top {
    border-top-color: red;
  }
}

To remove unused settings delete them from your config.cson.
