Wrap Guide

The wrap-guide extension places a vertical line in each editor at a certain column to guide your formatting so lines do not exceed a certain width.

By default the wrap-guide is placed at the 80th column.

Configuration

You can customize where the column is placed using the wrapGuide.columns config option.

{
  "wrapGuide": {
    "columns": [
      { "pattern": "\.mm$", "column": 200 },
      { "pattern": "\.cc$", "column": 120 }
    ]
  }
}

The above config example would place the guide at the 200th column for paths that end with .mm and place the guide at the 120th column for paths that end with .cc.

You can configure the color and/or width of the line by adding the following CSS to a custom stylesheet:

.wrap-guide {
  width: 10px;
  background-color: red;
}
