This commit adds a tool, codeformat.py, which will reformat C and Python
code to fit a certain style. By default the tool will reformat (almost)
all the original (ie not 3rd-party) .c, .h and .py files in this
repository. Passing filenames on the command-line to codeformat.py will
reformat only those. Reformatting is done in-place.
uncrustify is used for C reformatting, which is available for many
platforms and can be easily built from source, see
https://github.com/uncrustify/uncrustify. The configuration for uncrustify
is also added in this commit and values are chosen to best match the
existing code style. A small post-processing stage on .c and .h files is
done by codeformat.py (after running uncrustify) to fix up some minor
items:
- space inserted after * when used as multiplication with sizeof
- #if/ifdef/ifndef/elif/else/endif are dedented by one level when they are
configuring if-blocks and case-blocks.
For Python code, the formatter used is black, which can be pip-installed;
see https://github.com/psf/black. The defaults are used, except for line-
length which is set at 99 characters to match the "about 100" line-length
limit used in C code.
The formatting tools used and their configuration were chosen to strike a
balance between keeping existing style and not changing too many lines of
code, and enforcing a relatively strict style (especially for Python code).
This should help to keep the code consistent across everything, and reduce
cognitive load when writing new code to match the style.
And rename it to mp_obj_cast_to_native_base() to indicate this. This
allows users of this function to easily support native and native-subclass
objects in the same way (by just passing the object through this function).
Since commit 3aab54bf43 this piece of code is
no longer needed because the top-level function mp_obj_equal_not_equal()
now handles the case of user types, and will never call tuple's binary_op
function with MP_BINARY_OP_EQUAL and a non-tuple on the RHS.
Only the "==" operator was tested by the test suite in for such arguments.
Other comparison operators like "<" take a different path in the code so
need to be tested separately.
If the built-in input() is enabled (which it is by default) then it needs
some form of readline, so supply it with one when MICROPY_USE_READLINE=0.
Fixes issue #5658.
Follow up to recent commit ad7213d3c3, the
name "varg2" is misleading, vlist describes better that the argument is a
va_list. This name also matches CircuitPython, which already has such
helper functions.
This changes the signal used to trigger garbage collection from SIGUSR1 to
SIGRTMIN + 5. SIGUSR1 is quite common compared to SIGRTMIN (measured by
google search results) and is more likely to conflict with libraries that
may use the same signal.
POSIX specifies that there are at least 8 real-time signal so 5 was chosen
as a "random" number to further avoid potential conflict with libraries
that may use SIGRTMIN or SIGRTMAX.
Also, if we ever have a `usignal` module, it would be nice to leave SIGUSR1
and SIGUSR2 free for user programs.
The "random" module no longer uses the hardware RNG (the extmod version of
this module has a pseudo-random number generator), so the config option
MICROPY_PY_RANDOM_HW_RNG is no longer meaningful. This commit replaces it
with MICROPY_HW_ENABLE_RNG, which controls whether the hardware RNG is
included in the build.
The install target is current broken when PROG is used to override the
default executable name. This fixes it by removing the redundant TARGET
variable and uses PROG directly instead.
The install and uninstall targets are also moved to the common unix
Makefile so that all variants can be installed in the same way.
Currently it is not possible to override PREFIX when installing micropython
using the makefile. It is common practice to be able to run something like
this:
$ make install PREFIX=/usr DESTDIR=/tmp/staging
This fixes such usage.
These addresses were initially chosen to match the nRF24 Arduino library
examples but they are byte-reversed. So change them to be on-air
compatible with the Arduino library.
Also, the data sheet for the nRF24 says that RX data pipes 1-5 must share
the same top 32-bits, and must differ only in the LSbyte. The addresses
used here (while correct because they are on TX pipe and RX pipe 0) are
misleading in this sense, because it looks like they were chosen to share
the top 32-bits per the datasheet.
This provides a more consistent C-level API to raise exceptions, ie moving
away from nlr_raise towards mp_raise_XXX. It also reduces code size by a
small amount on some ports.
The default value for MICROPYPATH used in unix/main.c is
"~/.micropython/lib:/usr/lib/micropython" which has 2 problems when used in
the Windows port:
- it has a ':' as path separator but the port uses ';' so the entire string
is effectively discarded since it gets interpreted as a single path which
doesn't exist
- /usr/lib/micropython is not a valid path in a standard Windows
environment
Override the value with a suitable default.
If the exception doesn't need printf-style formatting then calling
mp_raise_msg is more efficient. Also shorten exception messages to match
style in core and other ports.
Both bool and namedtuple will check against other types for equality; int,
float and complex for bool, and tuple for namedtuple. So to make them work
after the recent commit 3aab54bf43 they would
need MP_TYPE_FLAG_NEEDS_FULL_EQ_TEST set. But that makes all bool and
namedtuple equality checks less efficient because mp_obj_equal_not_equal()
could no longer short-cut x==x, and would need to try __ne__. To improve
this, this commit splits the MP_TYPE_FLAG_NEEDS_FULL_EQ_TEST flags into 3
separate flags to give types more fine-grained control over how their
equality behaves. These new flags are then used to fix bool and namedtuple
equality.
Fixes issue #5615 and #5620.
This fix can be demonstrated by the following:
b = bytearray(32)
f = framebuf.FrameBuffer(b, 32, 8, framebuf.MONO_HLSB)
f.pixel(0, 0, 1)
print('MONO_HLSB', hex(b[0]))
b = bytearray(32)
f = framebuf.FrameBuffer(b, 32, 8, framebuf.MONO_HMSB)
f.pixel(0, 0, 1)
print('MONO_HMSB', hex(b[0]))
Outcome:
MONO_HLSB 0x80
MONO_HMSB 0x1
It's not needed. The C integer implicit promotion rules mean that the
uint8_t of the incoming character is promoted to a (signed) int, matching
the type of interrupt_char. Thus the uint8_t incoming character can never
be equal to -1 (the value of interrupt_char that indicate that interruption
is disabled).
The mp_keyboard_interrupt() function does exactly what is needed here, and
using it gets ctrl-C working when MICROPY_ENABLE_SCHEDULER is enabled on
these ports (and MICROPY_ASYNC_KBD_INTR is disabled).
