I'd better prefer "drop-in replacement" as for MySQL and MariaDB. |
|
The plan is to retain API compatibility of the C API in libespeak-ng and the command line in espeak-ng and speak-ng with the espeak equivalents. The "drop-in replacement" can then be done by creating symbolic links, either manually or by the |
|
It should be good on Unix-like systems. Don't know about Windows though. |

Special characters such as N, S1, etc. are not actually eating
characters. Their treatment should thus *not* update pre_ptr and post_ptr,
otherwise those would underflow/overflow, e.g. in the case
@) s (_NS1 [z]
this would overflow. This for instance noticeable with the memory sanitizer:

While trying to match _NS1, MatchRule is overflowing the buffer.
It happens that this had not usually posed problem because rules usually
have these non-eating special characters last in the rule and thus it wasn't
mattering that post_ptr is pointing outside valid text.

just initialize them directly from the Translator creation.

phonemes_name is only initialized when V_LANGUAGE is met. This is not
necessarily the case, notably with
testing espeak_SetVoiceByName("!v/Annie") (language variant; intonation)
Cannot set intonation: language not set, or is invalid.

Uninitialized value was created by an allocation of 'sbuf' in the stack frame of function 'TranslateClause'

It happens that this had not usually posed problem because rules usually
have these non-eating special characters last in the rule and thus it wasn't
mattering that post_ptr is pointing outside valid text.
