[asterisk-users] announcement: JS library for asterisk pattern matching and number manipulation

[marek]

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)
