| The files |
| |
| 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 |
