## 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.
