0059a5a88e libs/libc/stdio/lib_vsprintf.c and Kconfig:
- Numbered arguments now work by using two pass parsing and an argument list.
    The maximum number of numbered args is determined by CONFIG_LIBC_NL_ARGMAX
    which is then copied into NL_ARGMAX.
  - Size of pointer argument ('p') is determined before output.

include/limits.h:  Define NL_ARGMAX (as well as some of the other 'invariant
  values' per http://pubs.opengroup.org/onlinepubs/7908799/xsh/limits.h.html)

05a68d175b libs/libc/stdio/Kconfig: CONFIG_LIBC_NUMBERED_ARGS now depends on EXPERIMENTAL. Per Johannes: I tested numbered arguments on i.mx rt 1050, and it isn't working. Only on Linux/MSYS 64bit all relevant data types are size 8 bytes, and therefore my loop through the arg list is working. On 32bit systems, all is 4 bytes except floating point variables which is implicit 8 byte double. 2019-02-20 08:00:35 -06:00

a76e137ce2 Squashed commit of the following:
sched/init/nx_start.c:  Add support for CONFIG_BOARD_DRIVER_INITIALIZE.  If this option is selected then nx_start() will call a board-provided function board_driver_initialize() immediately after calling up_initialize().

    Rename CONFIG_BOARD_INITIALIZE to CONFIG_BOARD_LATE_INITIALIZE.

    Raname board_initialize() to board_late_initialize()

76a2f6c2a2 libs/libc/stdio: This commits makes the nano-printf the defualt logic for the printf family. The legacy printf is still available via CONFIG_LIBC_PRINT_LEGACY. This commit also modifies the nano-prinf configure: The PRINT_LEVEL is not long selectable. Instead, a not CONFIG_LIBC_PRINT_MINIMAL boolean setting was added and the PRINT_LEVEL is derived from a combination of CONFIG_LIBC_PRINT_MINIMAL, CONFIG_LIBC_FLOATINGPOINT, and CONFIG_LIBC_LONG_LONG. 2019-02-17 12:29:20 -06:00

67b16613ba libs/libc/stdio/lib_dtoa.c: Lots of risky turmoil to get this file closer to the NuttX coding style. Seems to check out, but still risky. libs/libc/stdio/lib_libdtoa.c: A fix for the %g format. The algorithm will sometimes generate number greater than the precision of type double. This adds a check if the precision has been exceeded and logic to remove the least significant garbage. 2019-02-16 18:08:38 -06:00

653ff2c34e Restore lib_sprintf(). It was removed because I thought was not used. But I was wrong; there is logic in drivers/syslog that depends on lib_sprintf().
This commits reverts a part of commit c271151d57.  That commit also removed lib_sscanf() which really is not needed.

38e93ede2b Revert "libs/libc/stdio: Fix the %f floating point output format."
The previous implementation was probably corect.  On Cygwin with GCC I see this:

int main(int argc, char **argv)
{
  printf("Value 1.2 is: [%f]\n", 1.2);
  printf("Value 0.1 is: [%f]\n", 0.1);
  printf("Value 0.0: [%f]\n", 0.0);
  printf("Value 347.6872: [%f]\n", 347.6872);
}

Generates output

Value 1.2 is: [1.200000]
Value 0.1 is: [0.100000]
Value 0.0: [0.000000]
Value 347.6872: [347.687200]

This reverts commit eb0223bc7f.

350295d009 Squashed commit of the following:
Author: Gregory Nutt <gnutt@nuttx.org>

    TODO:  Remove 'Missing fscanf()' bug
    Clean up remaining complaints for tools/nxstyle
    Apply tools/detab, rmcr, convert-comments, lowhex, and indent.sh to the new and highly modified files.

Author: Johannes <nivus.entwicklung@gmail.com>

    - Move vscanf logic to lib_sscanf.c  Switched to stream interface (tricky, because the old implementation used massive read ahead, which isn't suitable for streams, chars already read are gone).
    - Added scanf and fscanf
    - Added hh, h, and ll modifiers
    - Fixes for standard compliance in scanf
    - Fixes for standard compliance in strto... function family (don't consume single '-' or '+', allow sign in strotul(l))

e05149b745 libs/libc/stdio: Add newlib-nano fprintf as an option. This fprintf code was originally adapted from AVR libc and provides improved floating point output support, including 'g' mode and making 'f' mode include digits past the decimal by default. However, this version does not have any long long support. On a demonstration cortex M4 build, this version saves about 5kB of ROM. The newlib version can be found here: https://salsa.debian.org/electronics-team/toolchains/newlib-nano . That project is GPL overall, but the newlib-nano printf portions are BSD licensed as described in the COPYING.NEWLIB file. 2019-02-06 15:50:52 -06:00

659852acd5 libs/libc/unistd/lib_getopt.c: Add logic to reinitialize the stale context for the FLAT/PROTECTED builds. In these builds getopt() global varriables may be shared by many tasks. If any task exits the getopt() loop before all command line arguments have been parsed, then getopt() global variables will be left in a bad state. The next time getopt() is called, this logic should detect the bad state and force the state of getopt() to be re-initialized so that it can be reused. This logic is not full proof (it would fail, for example, if you tried to parse the same command line twice) but should catch the typical misuse cases. 2019-02-05 10:30:59 -06:00
