Strings
|
|
are enclosed by double or two single quotes:
|
|
"foo"
|
|
''foo''
|
|
Interpolation has only one form:
|
|
nix-repl> foo = "strval" // special repl-only syntax assignment
|
|
nix-repl> "${foo}"
|
|
"strval"
|
|
|
|
nix-repl> "${2+3}"
|
|
error: cannot coerce an integer to a string, at (string):1:2
|
|
// need to call integer -> string explicit conversions
|
|
|
|
Escaping ${...} within double quoted strings is done with the backslash.
|
|
|
|
nix-repl> "\${foo}"
|
|
"${foo}"
|
|
|
|
Escaping ${...} within two single quotes is done with '':
|
|
nix-repl> ''test ''${foo} test''
|
|
"test ${foo} test"
|
