2011-02-23strbuf: add fixed-length version of add_wrapped_textLibravatar Jeff King1-0/+2
The function strbuf_add_wrapped_text takes a NUL-terminated string. This makes it annoying to wrap strings we have as a pointer and a length. Refactoring strbuf_add_wrapped_text and all of its sub-functions to handle fixed-length strings turned out to be really ugly. So this implementation is lame; it just strdups the text and operates on the NUL-terminated version. This should be fine as the strings we are wrapping are generally pretty short. If it becomes a problem, we can optimize later. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-03-02Merge branch 'rs/optim-text-wrap'Libravatar Junio C Hamano1-1/+0
* rs/optim-text-wrap: utf8.c: speculatively assume utf-8 in strbuf_add_wrapped_text() utf8.c: remove strbuf_write() utf8.c: remove print_spaces() utf8.c: remove print_wrapped_text()
2010-02-20utf8.c: remove print_wrapped_text()Libravatar René Scharfe1-1/+0
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.

2009-10-19Add strbuf_add_wrapped_text() to utf8.[ch]Libravatar Johannes Schindelin1-0/+2
The newly added function can rewrap text according to a given first-line indent, other-indent and text width. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2009-02-04utf8: add utf8_strwidth()Libravatar Geoffrey Thomas1-0/+1
I'm about to use this pattern more than once, so make it a common function. Signed-off-by: Geoffrey Thomas <geofft@mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-01-06utf8_width(): allow non NUL-terminated inputLibravatar Junio C Hamano1-2/+2
The original interface assumed that the input string is always terminated with a NUL, but that wasn't too useful. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-01-06utf8: pick_one_utf8_char()Libravatar Junio C Hamano1-0/+3
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(). Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-02-27Actually make print_wrapped_text() usefulLibravatar Johannes Schindelin1-1/+1
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. With this, you can actually continue in the middle of a paragraph, not having to print everything into a buffer first.

2006-12-30commit-tree: cope with different ways "utf-8" can be spelled.Libravatar Junio C Hamano1-0/+2
People can spell config.commitencoding differently from what we internally have ("utf-8") to mean UTF-8. Try to accept them and treat them equally. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-12-26Move encoding conversion routine out of mailinfo to utf8.cLibravatar Junio C Hamano1-0/+6
This moves the body of convert_to_utf8() routine used in mailinfo to the utf8.c i18n library. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-12-24commit-tree: encourage UTF-8 commit messages.Libravatar Johannes Schindelin1-0/+8
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".
