## String escape character update |
|
|
|
The strings (both single-quoted and triple-quoted) in meson has been taught the |
|
same set of escape sequences as in Python. It is therefore now possible to use |
|
arbitrary bytes in strings, like for example NUL (`\0`) and other ASCII control |
|
characters. See the chapter about *Strings* in *Syntax* for more details. |
|
|
|
Potential backwards compatibility issue: Any valid escape sequence according to |
|
the new rules will be interpreted as an escape sequence instead of the literal |
|
characters. Previously only single-quote strings supported escape sequences and |
|
the supported sequences were `\'`, `\\` and `\n`. |
|
|
|
The most likely breakage is usage of backslash-n in triple-quoted strings. It |
|
is now written in the same way as in single-quoted strings: `\\n` instead of |
|
`\n`. In general it is now recommended to escape any usage of backslash. |
|
However, backslash-c (`\c`), for example, is still backslash-c because it isn't |
|
a valid escape sequence.
