I want to split a string by commas but only with a number before comma. The number must be present in result groups.
It works fine until input string contains a comma without a number before, this comma should be a part of value group.
What should i change in the first regexp?
const doSplit = (parameter_type) => parameter_type.split(/(?!\d+)\,\s/).map((option) => {
const matches = option.match(/(?<value>.+)\s(?<key>\d+)$/)
if(matches === null) {
return {Error: {option, parameter_type}}
}
return matches.groups
})
const list_a = "No reaction 0, Up 1, Down 3, Stop 5, Position 1 6, Position 2 7, Position 3 8, Position 4 9, Individual position 10, Enable automatic sun protection 14"
console.log(doSplit(list_a))
const list_b = "End position, no overflow 0, End position + 2% overflow 2, End position + 5% overflow 5, End position + 10% overflow 10, End position + 20% overflow 20, Total travel time + 10% Overflow 255"
console.log(doSplit(list_b))
You could do this with just one regex, and matchAll:
const regex = /\s*,?\s*(?<value>.+?)\s+(?<key>\d+)(?=,|$)/g;
const doSplit = (parameter_type) =>
Array.from(parameter_type.matchAll(regex), ({groups}) => groups);
const list_a = "No reaction 0, Up 1, Down 3, Stop 5, Position 1 6, Position 2 7, Position 3 8, Position 4 9, Individual position 10, Enable automatic sun protection 14"
console.log(doSplit(list_a))
const list_b = "End position, no overflow 0, End position + 2% overflow 2, End position + 5% overflow 5, End position + 10% overflow 10, End position + 20% overflow 20, Total travel time + 10% Overflow 255"
console.log(doSplit(list_b))
