Parser Reference: String ($) Token

Expand values as a string


The string token is used to tell murex to expand variables and subshells as a string (ie one single parameter) irrespective of the data that is stored in the string. One handy common use case is file names where traditional POSIX shells would treat spaces as a new file, whereas murex treats spaces as a printable character unless explicitly told to do otherwise.


» set: example="foo\nbar"

» out: $example

» out: @example
foo bar

In this example the second command is passing foo\nbar (\n escaped as a new line) to out. The third command is passing an array of two values: foo and bar.

The string and array tokens also works for subshells

» out: ${ ja: [Mon..Fri] }

» out: @{ ja: [Mon..Fri] }
Mon Tue Wed Thu Fri

The string token can also be used as a command too

» set: example="Hello World!"

» $example
Hello World!


Variables and subshells can be expanded inside double quotes, brace quotes as well as used naked. But they cannot be expanded inside single quotes.

» set: example="World!"

» out: Hello $example
Hello World!

» out: 'Hello $example'
Hello $example

» out: "Hello $example"
Hello World!

» out: (Hello $example)
Hello World!
