Flourish formatter
Flourish module for formatting numbers and dates using the format id's of the interpreter module.
Install
To install the module, type:
npm install @flourish/formatters
To add the module's settings block for number formatting, include something like the following in a templates' template.yml file:
- property: x_format
import: "@flourish/formatters/number-formatter"
Since you may well want different formatting for different variables or axes, it is quite likely you may want to include multiple settings blocks:
- property: y_format
import: "@flourish/formatters/number-formatter"
Usage
getFormatter(format_id)
This function return a formatter function with the given format_id
. For example:
import { getFormatter } from @flourish/formatter;
const numFormat = getFormatter("number$point_comma");
console.log(numFormat(12235.56)); // "12.235,56"
const dateFormat = getFormat("datetime$%d/%m/%Y");
console.log(Date.now()); // "20/01/2022"
initNumberFormatter(state_obj)
This function returns a function for generating a number-formatting function with additional properties that can be specified by the user of the template via the settings panel when the settings.yml from the number-formatter folder is included in the template.yml file. For example...
- Number formatting
- property: formatting
import: "@flourish/formatters/number-formatter"
// In state.js
const state = {
...
formatting = {};
...
}
// In draw.js
...
const getNumberFormatter = initNumberFormatter(state.formatting);
function draw() {
...
}
// In update.js
function update() {
...
const numberFormatter = getNumberFormatter(output_id);
const label = numberFormatter(value);
...
}
