* lib/fold: Catch error case from mbrtowc()Sam Mendoza-Jonas2016-03-151-3/+4
| | | | | | | | | | | | | The assert() statement in fold_text() only evaluates in a debug build. If mbrtowc() encounters an error return the portion of the string that has been parsed and stop. This avoids an issue with glibc 2.22 where previous calls to setlocale() failed and set an unsuitable locale. Since the error was not caught this resulted in an infinite loop when trying to access the Language screen. Signed-off-by: Sam Mendoza-Jonas <>
* lib/fold: Handle extra mbrtowc return caseSamuel Mendoza-Jonas2015-08-251-2/+3
| | | | | | | | Commit 9781a370 ("Handle mblen return code when n is zero.") in glibc changes the return value for when the number of bytes ('n') is zero. Add an extra condition to detect if we've reached the end of the buffer. Signed-off-by: Samuel Mendoza-Jonas <>
* lib/fold: fix warning with -DDEBUGJeremy Kerr2014-12-011-1/+1
| | | | | | | | | | | | | When compiling the fold code with DEBUG defined, we get: ../lib/fold/fold.c: In function 'fold_text': ../lib/fold/fold.c:37:3: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits] assert(bytes >= 0); ^ We should be comparing with != (size_t)-1, not >= 0 Signed-off-by: Jeremy Kerr <>
* lib/fold: Add support for multibyte stringsJeremy Kerr2014-09-231-11/+59
| | | | | | | | | | Currently, the fold_text function doesn't understand multibyte strings, so may break a line in the middle of a multibyte sequence. This change adds multibyte-awareness to the fold code, and uses proper width calculations for the contents of the folded string. Signed-off-by: Jeremy Kerr <>
* lib/fold: Add text fold utilityJeremy Kerr2014-01-312-0/+71
We want to fold help text into the ncurses UI, so add a little module to split text into lines. Signed-off-by: Jeremy Kerr <>
