($ str)
Macro defined at lib/core/string.lisp:188:2
Perform interpolation (variable substitution) on the string STR.
The string is a sequence of arbitrary characters which may contain an
unquote, of the form ~{foo} or ${foo}, where foo is a variable
name.
The ~{x} form will format the value using pretty, ensuring it is
readable. ${x} requires that x is a string, simply splicing the
value in directly.
Example:
> (let* [(x 1)] ($ "~{x} = 1"))
out = "1 = 1"
(bytes->string bytes)
Defined at lib/core/string.lisp:160:2
Convert a list of BYTES to a string.
Example:
> (bytes->string '(72 101 108 108 111))
out = "Hello"
(char-at xs x)
Defined at lib/core/string.lisp:12:2
Index the string XS, returning the character at position X.
Example:
> (string/char-at "foo" 1)
out = "f"
(chars->string chars)
Defined at lib/core/string.lisp:170:2
Convert a list of CHARS to a string.
Example:
> (chars->string '("H" "e" "l" "l" "o"))
out = "Hello"
(concat xs separator)
Defined at lib/core/string.lisp:22:2
Concatenate a list of strings, using an optional separator.
Example
> (concat '("H" "i" "!"))
out = "Hi!"
> (concat '("5" "+" "1") " ")
out = "5 + 1"
(ends-with? str suffix)
Defined at lib/core/string.lisp:122:2
Determine whether STR ends with SUFFIX.
Example:
> (string/ends-with? "Hello, world" "world")
out = true
(quoted str)
Defined at lib/core/string.lisp:93:1
Quote the string STR so it is suitable for printing.
Example:
> (string/quoted "\n")
out = "\"\\n\""
(split text pattern limit)
Defined at lib/core/string.lisp:38:2
Split the string given by TEXT in at most LIMIT components, which are
delineated by the Lua pattern PATTERN.
It is worth noting that an empty pattern ("") will split the
string into individual characters.
Example
> (split "foo-bar-baz" "-")
out = ("foo" "bar" "baz")
> (split "foo-bar-baz" "-" 1)
out = ("foo" "bar-baz")
(starts-with? str prefix)
Defined at lib/core/string.lisp:112:2
Determine whether STR starts with PREFIX.
Example:
> (string/starts-with? "Hello, world" "Hello")
out = true
(string->bytes str)
Defined at lib/core/string.lisp:132:2
Convert a string to a list of character bytes.
Example:
> (string->bytes "Hello")
out = (72 101 108 108 111)
(string->chars str)
Defined at lib/core/string.lisp:147:2
Convert a string to a list of characters.
Example:
> (string->chars "Hello")
out = ("H" "e" "l" "l" "o")
(trim str)
Defined at lib/core/string.lisp:82:2
Remove whitespace from both sides of STR.
Example:
> (string/trim " foo\n\t")
out = "foo"
