[asterisk-users] announcement: JS library for asterisk pattern matching and number manipulation
hi,
If you are using JavaScript for *AGI/ARI/AMI we made small library for
asterisk dialplan pattern matching and number manipulation
https://www.npmjs.com/package/asterisk-pattern-matching
examples
const { validateNumber } = require("asterisk-pattern-matching")
// list of examples, return true or false
validateNumber('_X.', 123456789) // true
validateNumber('_[+0-9].', 123456789) // true
validateNumber('_X.', '+123456789') // false
// function to verify the asterisk pattern truth and parse number by
given settings
const { parseNumber } = require("asterisk-pattern-matching")
// list of examples, function ends at first pattern match
const myPatterns = [
/*
{
pattern:, // (String) asterisk pattern
deleteFromStart:, // (String|Number) indicates, how many chars
should be removed from number's START
deleteFromEnd:, // (String|Number)indicates, how many chars
should be removed from number's END
prefix:, // (String|Number) indicates, what should be added
to number's START
suffix: // (String|Number) indicates, what should be added
to number's END
},
*/
{
pattern: '_77X.',
deleteFromStart: 1,
deleteFromEnd: 1,
prefix: '***',
suffix: '###'
},
{
pattern: '_[*#0-9].',
deleteFromStart: '2',
deleteFromEnd: '1',
prefix: 123,
suffix: 321
},
{
pattern: '_+X.',
deleteFromStart: 4,
deleteFromEnd: 3,
prefix: '0',
suffix: '123'
}
]
// [] = removed, () = added
// second pattern (_[*#0-9].) from variable myPatterns is valid,
// (123)[+4]20999888-7[7](321) => result 12320999888-7321
// function stops after first valid pattern
parseNumber('*420999888-77', myPatterns)
// last pattern (_+X) from variable myPatterns is valid,
// (9)[+420]999888[-77](123) => result 0999888123
parseNumber('+420999888-77', myPatterns)
