printable-characters
A little helper for handling strings containing zero width characters, ANSI styling, whitespaces, newlines, weird Unicode 💩 symbols, etc.
Determining the real (visible) length of a string
1const { strlen } = require ('printable-characters') 2 3strlen ('foo bar') // === 7 4strlen ('\u001b[106mfoo bar\u001b[49m') // === 7
Detecting blank text
1const { isBlank } = require ('printable-characters') 2 3isBlank ('foobar') // === false 4isBlank ('\u001b[106m \t \t \n \u001b[49m') // === true
Obtaining a blank string of the same width
1const { blank } = require ('printable-characters') 2 3blank ('💩') // === ' ' 4blank ('foo') // === ' ' 5blank ('\tfoo \nfoo') // === '\t \n ' 6blank ('\u001b[22m\u001b[1mfoo \t\u001b[39m\u001b[22m')) // === ' \t'
Matching invisible characters
1const { ansiEscapeCodes, zeroWidthCharacters } = require ('printable-characters') 2 3const s = '\u001b[106m' + 'foo' + '\n' + 'bar' + '\u001b[49m' 4 5s.replace (ansiEscapeCodes, '') // === 'foo\nbar' 6 .replace (zeroWidthCharacters, '') // === 'foobar'
Getting the first N visible symbols, preserving the invisible parts
Use for safely truncating strings to maximum width without breaking ANSI codes:
1const { first } = require ('printable-characters') 2 3const s = '\u001b[22mfoobar\u001b[22m' 4 5first (s, 0) // === '\u001b[22m\u001b[22m' 6first (s, 1) // === '\u001b[22mf\u001b[22m' 7first (s, 3) // === '\u001b[22mfoo\u001b[22m' 8first (s, 6) // === '\u001b[22mfoobar\u001b[22m'
Extracting the invisible parts followed by the visible ones (parsing)
1const { partition } = require ('printable-characters') 2 3partition ('') // [ ]) 4partition ('foo') // [['', 'foo'] ]) 5partition ('\u001b[1mfoo') // [['\u001b[1m', 'foo'] ]) 6partition ('\u001b[1mfoo\u0000bar') // [['\u001b[1m', 'foo'], ['\u0000', 'bar'] ]) 7partition ('\u001b[1mfoo\u0000bar\n') // [['\u001b[1m', 'foo'], ['\u0000', 'bar'], ['\n', '']])
Applications
- as-table — a simple function that prints objects as ASCII tables
- string.bullet — ASCII-mode bulleting for the list-style data
- string.ify — a fancy pretty printer for the JavaScript entities
- Ololog! — a better
console.logfor the log-driven debugging junkies!
TODO
Handle multi-component emojis, as in this article:
1assert.equal (strlen ('👩❤️💋👩'), 1) // FAILING, see http://blog.jonnew.com/posts/poo-dot-length-equals-two for possible solution 2assert.equal (blank ('👩❤️💋👩'), ' ') // FAILING, see http://blog.jonnew.com/posts/poo-dot-length-equals-two for possible solution
