• Add configurable implicit flags [done]
• Separate SafeRegex and CleanRegex into to two packages, so users can choose what they want #103
• Add documentation to each T-Regx public method #17 [in progress]
• Release 1.0
• Revamp of t-regx.com documentation [in progress]

API

You, choose the interface: - I choose to keep PHP methods (but protected from errors):

Why T-Regx stands out?

• No change in API!

  • You can use T-Regx safe features and exception-based error handling, without changing your API.

  Simply swap

  preg_match()

  to

  preg::match()

  , and your method is safe! Arguments and return types remain the same.

• Prepared patterns

Using user data (for example with

preg_quote()

Pattern::inject()

Pattern::bind()

Pattern::format()

• Working with the developer

  • Errors:
    • Not even touching your error handlers in any way
    • Converts all PCRE notices/error/warnings to exceptions
    • Preventing fatal errors
  • Strings:
    • Tracking offset and subjects while replacing strings
    • Fixing error with multi-byte offset (utf-8 safe)

• Automatic delimiters for your pattern

  Surrounding slashes or tildes (

  /pattern/

  or

  ~patttern~

  ) are not compulsory.

• Converting Warnings/Errors to Exceptions

  • Malformed patterns in

    preg_()

    methods don't make

    preg_last_error()

    to return error.
  • Notices, warnings or errors during

    preg::

    are converted to exceptions.

  • preg_()

    can never fail, because it throws

    PregException

    on warning/error.
  • In some cases,

    preg_()

    methods might fail, return

    false

    /

    null

    and NOT trigger a warning. Separate exception,

    SuspectedReturnPregException

    is then thrown by T-Regx.

• Written with clean API

  • Descriptive, chainable interface
  • SRP methods
  • UTF-8 support out-of-the-box

  • No Reflection used

    ,

    No (...varargs)

    ,

    No (boolean arguments, true)

    ,

    (No flags, 1)

    ,

    [No [nested, [arrays]]]

• Protects your from fatal errors

  Certain arguments cause fatal errors with

  preg_()

  methods. T-Regx will throw a catchable exception, instead of a Fatal Error.
