This will highly simplify the docstring integration. I measured "hg log
--style=changelog" duration on mercurial itself and could not detect any
difference.
It aims to fix javascript error of hgweb's graph view in Japanese 'cp932'
encoding.
'cp932' contains multibyte characters ending with '\x5c' (backslash),
e.g. '\x94\x5c' for Japanese Kanji 'Noh'.
Due to json filter escapes '\' to '\\', multibyte string ending with
'\x5c' is translated to "xxx\", resulting javascript parse error on
a web browser.
This patch changes json() to pass unicode to jsonescape().
Unicode decoding error handler changed to 'replace' by Patrick Mézard.
Mercurial has problem around text wrapping/filling in MBCS encoding
environment, because standard 'textwrap' module of Python can not
treat it correctly. It splits byte sequence for one character into two
lines.
According to unicode specification, "east asian width" classifies
characters into:
W(ide), N(arrow), F(ull-width), H(alf-width), A(mbiguous)
W/N/F/H can be always recognized as 2/1/2/1 bytes in byte sequence,
but 'A' can not. Size of 'A' depends on language in which it is used.
Unicode specification says:
If the context(= language) cannot be established reliably they
should be treated as narrow characters by default
but many of class 'A' characters are full-width, at least, in Japanese
environment.
So, this patch treats class 'A' characters as full-width always for
safety wrapping.
This patch focuses only on MBCS safe-ness, not on writing/printing
rule strict wrapping for each languages
MBCS sensitive textwrap class is originally implemented
by ITO Nobuaki <daydream.trippers@gmail.com>.
It ensures that at least "(none)" is returned in case the argument
passed is None or ''. This is primarily useful to render empty
changelog messages for hgweb but may be useful for others, too.
Adds a new template filter for removing directory levels from a
string. Examples:
{foo|stripdir} -> 'foo'
{foo/bar|stripdir} -> 'foo'
{foo/bar/more|stripdir} -> 'foo/bar'
{foo/bar/more|stripdir|stripdir} -> 'foo'
datestr:
- add format specifiers %1 and %2 for timezone hours and minutes
- remove timezone and timezone format options
- correctly find timezone hours and minutes for fractional and negative timezones
- update users
strdate:
- correctly find timezone hours and minutes for fractional and negative timezones
Useful for creating XML documents directly from Hg logging. Can also be used for
HTML. For use in content, will escape '&', '<', and for completeness '>'
(although it is not strictly necessary). For use in attributes, will also escape
' and ". Will also replace nonprinting (ASCII) control characters with spaces,
since these are illegal in XML.
