chalk-template
Terminal string styling with tagged template literals
Install
npm install chalk-template
Usage
import chalkTemplate from 'chalk-template';
import chalk from 'chalk';
const log = console.log;
log(chalkTemplate`
CPU: {red ${cpu.totalPercent}%}
RAM: {green ${ram.used / ram.total * 100}%}
DISK: {rgb(255,131,0) ${disk.used / disk.total * 100}%}
`);
log(chalk.red.bgBlack(chalkTemplate`2 + 3 = {bold ${2 + 3}}`));
const miles = 18;
const calculateFeet = miles => miles * 5280;
console.log(chalk`
There are {bold 5280 feet} in a mile.
In {bold ${miles} miles}, there are {green.bold ${calculateFeet(miles)} feet}.
`);
console.log(chalk`
There are also {#FF0000 shorthand hex styles} for
both the {#ABCDEF foreground}, {#:123456 background},
or {#ABCDEF:123456 both}.
`);
API
Blocks are delimited by an opening curly brace ({), a style, some content, and a closing curly brace (}).
Template styles are chained exactly like normal Chalk styles. The following two statements are equivalent:
import chalk from 'chalk';
import chalkTemplate from 'chalk-template';
console.log(chalk.bold.rgb(10, 100, 200)('Hello!'));
console.log(chalkTemplate`{bold.rgb(10,100,200) Hello!}`);
Note that function styles (rgb(), etc.) may not contain spaces between parameters.
All interpolated values (chalkTemplate`${foo}`) are converted to strings via the .toString() method. All curly braces ({ and }) in interpolated value strings are escaped.
Template function
You may also use the template function as an alternative to the tagged template function.
import {template} from 'chalk-template';
console.log(template('Today is {red hot}'));
