René Scharfe	462749b728	utf8.c: speculatively assume utf-8 in strbuf_add_wrapped_text() is_utf8() works by calling utf8_width() for each character at the supplied location. In strbuf_add_wrapped_text(), we do that anyway while wrapping the lines. So instead of checking the encoding beforehand, optimistically assume that it's utf-8 and wrap along until an invalid character is hit, and when that happens start over. This pays off if the text consists only of valid utf-8 characters. The following command was run against the Linux kernel repo with git 1.7.0: $ time git log --format='%b' v2.6.32 >/dev/null real 0m2.679s user 0m2.580s sys 0m0.100s $ time git log --format='%w(60,4,8)%b' >/dev/null real 0m4.342s user 0m4.230s sys 0m0.110s And with this patch series: $ time git log --format='%w(60,4,8)%b' >/dev/null real 0m3.741s user 0m3.630s sys 0m0.110s So the cost of wrapping is reduced to 70% in this case.

René Scharfe	68ad5e1e9c	utf8.c: remove strbuf_write() The patch before the previous one made sure that all callers of strbuf_add_wrapped_text() supply a strbuf. Replace all calls of strbuf_write() with regular strbuf functions and remove it.

René Scharfe	3c0ff44a1e	utf8.c: remove print_spaces() The previous patch made sure that strbuf_add_wrapped_text() (and thus strbuf_add_indented_text(), too) always get a strbuf. Make use of this fact by adding strbuf_addchars(), a small helper that adds a char the specified number of times to a strbuf, and use it to replace print_spaces().

René Scharfe	bb96a2c900	utf8.c: remove print_wrapped_text() strbuf_add_wrapped_text() is called only from print_wrapped_text() without a strbuf (in which case it writes its results to stdout). At its only callsite, supply a strbuf, call strbuf_add_wrapped_text() directly and remove the wrapper function.

René Scharfe	37bb5d7443	strbuf_add_wrapped_text(): factor out strbuf_add_indented_text() Add a new helper function, strbuf_add_indented_text(), to indent text without a width limit, and call it from strbuf_add_wrapped_text(). It respects both indent (applied to the first line) and indent2 (applied to the rest of the lines); indent2 was ignored by the indent-only path of strbuf_add_wrapped_text() before the patch. Two simple test cases are added, one exercising strbuf_add_wrapped_text() and the other strbuf_add_indented_text().

Junio C Hamano	00d3947366	Teach --wrap to only indent without wrapping When a zero or negative width is given to "shortlog -w<width>,<in1>,<in2>" and --format=%[wrap(w,in1,in2)...%], just indent the text by in1 without wrapping. Signed-off-by: Junio C Hamano <gitster@pobox.com>	15 years ago

Johannes Schindelin	ae0b270230	print_wrapped_text(): allow hard newlines print_wrapped_text() will insert its own newlines. Up until now, if the text passed to it contained newlines, they would not be handled properly (the wrapping got confused after that). The strategy is to replace a single new-line with a space, but keep double new-lines so that already-wrapped text with empty lines between paragraphs will be handled properly. However, single new-line characters are only handled this way if the character after it is an alphanumeric character, as per Linus' suggestion.

Junio C Hamano	396ccf1fcb	utf8: pick_one_utf8_char() utf8_width() function was doing two different things. To pick a valid character from UTF-8 stream, and compute the display width of that character. This splits the former to a separate function pick_one_utf8_char().

Ramsay Jones	fd547a972a	Fix a "pointer type missmatch" warning. In particular, the second parameter in the call to iconv() will cause this warning if your library declares iconv() with the second (input buffer pointer) parameter of type const char **. This is the old prototype, which is none-the-less used by the current version of newlib on Cygwin. (It appears in old versions of glibc too).

Ramsay Jones	2832114532	Fix some "comparison is always true/false" warnings. On Cygwin the wchar_t type is an unsigned short (16-bit) int. This results in the above warnings from the return statement in the wcwidth() function (in particular, the expressions involving constants with values larger than 0xffff). Simply replace the use of wchar_t with an unsigned int, typedef-ed as ucs_char_t. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago

Johannes Schindelin	094e03b039	Actually make print_wrapped_text() useful Now, it returns the current column, does not add a newline, and you can pass a negative indent, to indicate that the indent was already printed.

Johannes Schindelin	9e83266525	commit-tree: encourage UTF-8 commit messages. Introduce is_utf() to check if a text looks like it is encoded in UTF-8, utf8_width() to count display width, and implements print_wrapped_text() using them. git-commit-tree warns if the commit message does not minimally conform to the UTF-8 encoding when i18n.commitencoding is either unset, or set to "utf-8".
