// This script can be used to build custom colour-scheme css files.
|
|
//
|
|
// 1. Create a copy of packages/node_modules/@node-red/editor-client/src/sass/colors.scss
|
|
// and change the values to the desired colours.
|
|
//
|
|
// 2. Run this script, providing the path to the custom file using the --in option
|
|
//
|
|
// 3. Save the output of the script to a file - either redirect its output,
|
|
// or use the --out option.
|
|
//
|
|
// 4. Edit your settings file to set the theme:
|
|
// editorTheme: {
|
|
// page: {
|
|
// css: "/path/to/file/generated/by/this/script"
|
|
// }
|
|
// }
|
|
//
|
|
// 5. Restart Node-RED
|
|
//
