Escaping Special Characters
When writing expressions you may need to enter a character that has special meaning. For example, a string could include a double-quote, but in the expression PhixFlow will read this as the end of the string. To tell PhixFlow to ignore a special character, you can use the backslash character.
You must use a backslast to escape any of the special characters listed in the table below.
| Character | Type | Escape string |
|---|---|---|
backspace | Represented As | "\b" |
| Escaped | "\\\\b" | |
| form feed | Represented As | "\f" |
| Escaped | "\\\\f" | |
| tab | Represented As | "\t" |
| Escaped | "\\\\t" | |
| carraige return | Represented As | "\r" |
| Escaped | "\\\\r" | |
| newline | Represented As | "\n" |
| Escaped | "\\\\n" | |
| backslash | Represented As |
|
| Escaped | "\\\\\\\\" | |
| double quote | Represented As | '"' |
| Escaped | '\\\\"' |
Example
The following macro escapes special characters.
do(
$value = $args[1],
$value = replaceAll( $value , "\b","\\\\b"),
$value = replaceAll( $value , "\f","\\\\f"),
$value = replaceAll( $value , "\t","\\\\t"),
$value = replaceAll( $value , "\r","\\\\r"),
$value = replaceAll( $value , "\n","\\\\n"),
$value = replaceAll( $value , "\\\\","\\\\\\\\"),
$value = replaceAll( $value , '"','\\\\"')
)
