From: Kevin Day Date: Fri, 3 Jun 2022 03:46:36 +0000 (-0500) Subject: Bugfix: Finish addressing trimmed printing is not working as expected. X-Git-Tag: 0.5.10~79 X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=88aa80209dc006332b2cf85a01d5be42a17b198f;p=fll Bugfix: Finish addressing trimmed printing is not working as expected. The previous commit c8c59e16bb4cb7936142bff4815b302ad57138de is incomplete. Finish addressing the todos and also catch other cases where trimmed printing is not working as expected. The addition of the combining character checks introduces additional complexity. This complexity is stronger reason to write unit tests for fl_print. There is a lot of room for error as a result of this additional logic. --- diff --git a/level_1/fl_print/c/print.h b/level_1/fl_print/c/print.h index ad6a0b9..22e9941 100644 --- a/level_1/fl_print/c/print.h +++ b/level_1/fl_print/c/print.h @@ -359,10 +359,15 @@ extern "C" { * F_parameter (with error bit) if a parameter is invalid. * F_utf_not (with error bit) if character is an invalid UTF-8 character. * - * Errors (with error bit) from: f_utf_is_valid() + * Errors (with error bit) from: f_utf_is_combining(). + * Errors (with error bit) from: f_utf_is_valid(). * Errors (with error bit) from: f_utf_is_whitespace(). * * @see fputc_unlocked() + * + * @see f_utf_is_combining() + * @see f_utf_is_valid() + * @see f_utf_is_whitespace() */ #ifndef _di_fl_print_trim_ extern f_status_t fl_print_trim(const f_string_t string, const f_array_length_t length, FILE * const stream);
