Julia Language String Macros
Syntax
- macro"string" # short, string macro form
- @macro_str "string" # long, regular macro form
- macro`command`
Remarks
String macros are not quite as powerful as plain old strings — because interpolation must be implemented in the macro's logic, string macros are unable to contain string literals of the same delimiter for interpolation.
For instance, although
julia> "$("x")"
"x"
works, the string macro text form
julia> doc"$("x")"
ERROR: KeyError: key :x not found
gets parsed incorrectly. This can be somewhat mitigated by using triple-quotes as the outer string delimiter;
julia> doc"""$("x")"""
"x"
does indeed work properly.
