\xhh, matches a two-byte UTF-8 character if the valueĪfter " \0" up to two further octal digits are read. The original hexadecimal escape sequence, It is interpreted as a UTF-8 character whose code number is the Read (letters can be in upper or lower case).Īllowed, where the contents of the braces is a string of hexadecimalĭigits. Then bit 6 of the character (hex 40) is inverted.Īfter " \x", up to two hexadecimal digits are If " x" is a lower case letter, it is converted The precise effect of " \cx" is as follows: \ddd character with octal code ddd, or backreference \r carriage return (hex 0D) \R line break: matches \n, \r and \r\n \t tab (hex 09) \xhh \a alarm, that is, the BEL character (hex 07) \cx "control-x", where x is any character \e escape (hex 1B) \f formfeed (hex 0C) \n newline (hex 0A) \p Usually easier to use one of the following escape sequences Is no restriction on the appearance of non-printing characters,Īpart from the binary zero that terminates a pattern,īut when a pattern is being prepared by text editing, it is Non-printing characters in patterns in a visible manner. Whitespace or "#" character as part of the pattern.Ī second use of backslash provides a way of encoding An escaping backslash can be used to include a Whitespace in the pattern (other than in a character class) andĬharacters between a "#" outside a character class and the next newlineĬharacter are ignored. Thus if \ has to be matched with a regularĮxpression \\, then "\\\\" or '\\\\' must be used in PHP code. Single and double quoted PHP strings have special Particular, if you want to match a backslash, you write "\\". With "\" to specify that it stands for itself. Meta-character, so it is always safe to precede a non-alphanumeric This applies whether or not theįollowing character would otherwise be interpreted as a This use ofīackslash as an escape character applies both inside andįor example, if you want to match a "*" character, you write Firstly, if it isįollowed by a non-alphanumeric character, it takes away any The backslash character has several uses. And if you find a great use case for these settings, I'd love to hear about it.Getting Started Introduction A simple tutorial Language Reference Basic syntax Types Variables Constants Expressions Operators Control Structures Functions Classes and Objects Namespaces Enumerations Errors Exceptions Fibers Generators Attributes References Explained Predefined Variables Predefined Exceptions Predefined Interfaces and Classes Predefined Attributes Context options and parameters Supported Protocols and Wrappers Security Introduction General considerations Installed as CGI binary Installed as an Apache module Session Security Filesystem Security Database Security Error Reporting User Submitted Data Hiding PHP Keeping Current Features HTTP authentication with PHP Cookies Sessions Dealing with XForms Handling file uploads Using remote files Connection handling Persistent Database Connections Command line usage Garbage Collection DTrace Dynamic Tracing Function Reference Affecting PHP's Behaviour Audio Formats Manipulation Authentication Services Command Line Specific Extensions Compression and Archive Extensions Cryptography Extensions Database Extensions Date and Time Related Extensions File System Related Extensions Human Language and Character Encoding Support Image Processing and Generation Mail Related Extensions Mathematical Extensions Non-Text MIME Output Process Control Extensions Other Basic Extensions Other Services Search Engine Extensions Server Specific Extensions Session Extensions Text Processing Variable and Type Related Extensions Web Services Windows Only Extensions XML Manipulation GUI Extensions Keyboard Shortcuts ?

I'm very excited to see how I can incorporate PSStyle into my everyday PowerShell work and scripting. Import-PSStyleFileInfo c:\work\fileinfo.json In your PowerShell profile script, dot source the PS1 file and then import the settings. Export-PSStyleFileInfo C:\work\fileinfo.json Once you've configured your FileInfo settings, export them to a JSON file. Save the PS1 file to your desktop, and dot source it. I wrote a set of PowerShell functions, one to export FileInfo settings to a JSON file and another to import them. Since I've been having so much fun with this, I realized I needed a good way to configure my FileInfo settings without having to constantly be editing a profile script. It isn't that difficult to define a style for a group of file extensions.
