asnprintf.c
|
|
printf-args.c
|
|
printf-args.h
|
|
printf-parse.c
|
|
printf-parse.h
|
|
vasnprintf.c
|
|
vasnprintf.h
|
|
|
|
are taken from the vasnprintf module of the GNUlib package, which can
|
|
be found at:
|
|
|
|
http://www.gnu.org/software/gnulib/
|
|
|
|
All files have been modified to include g-gnulib.h.
|
|
|
|
vasnprintf.c has also been modified to include support for long long
|
|
printing if the system printf doesn't. This code is protected by
|
|
#ifndef HAVE_LONG_LONG_FORMAT.
|
|
|
|
Code has been added to printf-args.[ch], printf-parse.c and vasnprintf.c
|
|
to support printing of __int64 values with the I64 format modifier. This
|
|
is protected by #ifdef HAVE_INT64_AND_I64.
|
|
|
|
The files
|
|
|
|
printf.h
|
|
printf.c
|
|
g-gnulib.h
|
|
|
|
have been written by me. printf.[hc] contain implementations of the
|
|
remaining functions in the printf family based on vasnprintf.
|
|
g-gnulib.h is included by all source files in order to move all
|
|
exported functions to the _g_gnulib namespace, replace malloc by
|
|
g_malloc and make sure that snprintf is only used if it implements
|
|
C99 return value semantics.

To update:
|
|
* Create an empty directory, put a configure.ac file into it.
|
|
* Run gnulib-tool --lgpl=2 --import --lib=libgnu --source-base=lib \
|
|
--m4-base=m4 --doc-base=doc --tests-base=tests --aux-dir=. \
|
|
--no-conditional-dependencies --no-libtool --macro-prefix=gl \
|
|
isnand-nolibm isnanf-nolibm isnanl-nolibm printf-frexpl \
|
|
signbit vasnprintf
|
|
* Then pick out the files that are already in glib/gnulib subdirectory
|
|
(the rest of the files are not needed):
|
|
|
|
asnprintf.c
|
|
c++defs.h
|
|
float+.h
|
|
fpucw.h
|
|
gnulib_math.h.in (rename from math.in.h)
|
|
isnan.c
|
|
isnand.c
|
|
isnand-nolibm.h
|
|
isnanf.c
|
|
isnanf-nolibm.h
|
|
isnanl.c
|
|
isnanl-nolibm.h
|
|
printf-args.c
|
|
printf-args.h
|
|
printf-frexp.c
|
|
printf-frexp.h
|
|
printf-frexpl.c
|
|
printf-frexpl.h
|
|
printf-parse.c
|
|
printf-parse.h
|
|
signbitd.c
|
|
signbitf.c
|
|
signbitl.c
|
|
vasnprintf.c
|
|
vasnprintf.h
|
|
verify.h
|
|
xsize.h
|
|
|
|
* Then look at the glib-gnulib.patch and re-introduce custom glib changes
|
|
contained in that patch.
|
|
* If gnulib_math.h.in got some new @variables@, these will have to be
|
|
somehow set in meson.build, otherwise meson would warn about them
|
|
at configure stage
