Text utilities

Notes on using this page

• Click fieldset legends ▼ above to toggle show/hide.
• Some controls have tooltips with details.
• Line endings are standardized as LFs ("\n" or 0x0A if you prefer) to be cross-browser, including before hashing.
• The JavaScript String.split() function is overriden and should be cross-browser compatible with ECMA-262 v3 specifications (thanks to Stephen Levithan, see credits below). Your browser's original split function remains accessible with String._$$split().
• You can bookmark this page and automatically load scripts by adding load=script_url GET parameters to the current URL (?load=url1&load=url2 should work fine). You can also bookmark with the #hash of the wanted control set to directly activate it on page load: #geek_utils, #hash, #regexp, #js, #base.
• You can save this page to use it locally (Mozilla users, remember to choose “Complete HTML” file type) but the Flash copy button won't work, so only IE users will be able to click-copy.
• There are some keyboard shortcuts that you may want to use:
  • Ctrl + Shift + T focuses the input textarea
  • Ctrl + Shift + J and Ctrl + Shift + E both evaluate the input as JavaScript
  • Ctrl + Shift + F expands the search/replace fieldset and focuses the search textarea
  • Ctrl + Shift + H expands the hash fieldset and focuses the “Hash” button
  • Ctrl + Shift + B expands the base conversion fieldset and focuses the byte conversion button
  • Ctrl + Shift + N expands the base conversion fieldset and focuses the base conversion button
• When using the function regex/search-replace, the arguments for the functions are:
  • 1: The matched expression
  • 2 to n: The matched subpatterns (not applicable if not in regex mode or when applying the function to pieces)
  • n+1: The offset of the matched expression/piece in the original input text
  • n+2: The original input text

Known bugs

• Javascript's regex limitations, like lack of Unicode or lookbehind support
• As a consequence, incorrect non-ASCII character support, affecting some word-based features (title/camel case, words counting, etc.).

Credits for JavaScript implementations

• The copy button uses (except for Internet Explorer) the ZeroClipboard Flash Plugin (requires Flash Player ≥ 9)
• The Title Case function is John Resig's, from an idea of John Gruber
• The Prettify Punctuation function is provided by JsPrettify
• Hashing implementations are Paul Johnson's
• Base64 implementation is based on WebToolkit's
• UTF-8 encoding/decoding uses Johan Sundström's trick
• Internal use of Steven Levithan's cross-browser split implementation
• The keyboard shortcuts are mapped using shortcut.js by Binny V A on OpenJS
• The Word-Wrap function is Kevin van Zonneveld's , original from Jonas Raoni Soares Silva
