There were several different spellings of MicroPython present in comments,
when there should be only one.
all: Unify header guard usage.2017-07-18T01:57:39+00:00Alexander Steffendevel.20.webmeister@spamgourmet.com2017-06-29T21:14:58+00:00urn:sha1:299bc625864b9e624ed599c94a5f95870516139a
The code conventions suggest using header guards, but do not define how
those should look like and instead point to existing files. However, not
all existing files follow the same scheme, sometimes omitting header guards
altogether, sometimes using non-standard names, making it easy to
accidentally pick a "wrong" example.
This commit ensures that all header files of the MicroPython project (that
were not simply copied from somewhere else) follow the same pattern, that
was already present in the majority of files, especially in the py folder.
The rules are as follows.
Naming convention:
* start with the words MICROPY_INCLUDED
* contain the full path to the file
* replace special characters with _
In addition, there are no empty lines before #ifndef, between #ifndef and
one empty line before #endif. #endif is followed by a comment containing
the name of the guard macro.
py/grammar.h cannot use header guards by design, since it has to be
included multiple times in a single C file. Several other files also do not
need header guards as they are only used internally and guaranteed to be
included only once:
* MICROPY_MPHALPORT_H
* mpconfigboard.h
* mpconfigport.h
* mpthreadport.h
* pin_defs_*.h
* qstrdefs*.h
py/lexer: Convert mp_uint_t to size_t where appropriate.2017-02-17T01:44:24+00:00Damien Georgedamien.p.george@gmail.com2017-02-17T01:44:24+00:00urn:sha1:5124a940670dbb5c07f6681070b3d1580c71d697py/lexer: Simplify handling of line-continuation error.2017-02-17T00:30:14+00:00Damien Georgedamien.p.george@gmail.com2017-02-17T00:30:14+00:00urn:sha1:773278ec3030ea9ed809c5a248fde2278ce4b557
Previous to this patch there was an explicit check for errors with line
continuation (where backslash was not immediately followed by a newline).
But this check is not necessary: if there is an error then the remaining
logic of the tokeniser will reject the backslash and correctly produce a
syntax error.
py/lexer: Use strcmp to make keyword searching more efficient.2017-02-17T00:10:35+00:00Damien Georgedamien.p.george@gmail.com2017-02-17T00:10:35+00:00urn:sha1:ae436797927c3c9f7ccdc25dd78af3dd279ca7ff
Since the table of keywords is sorted, we can use strcmp to do the search
and stop part way through the search if the comparison is less-than.
Because all tokens that are names are subject to this search, this
optimisation will improve the overall speed of the lexer when processing
a script.
The change also decreases code size by a little bit because we now use
strcmp instead of the custom str_strn_equal function.
py/lexer: Permanently disable the mp_lexer_show_token function.2016-12-21T23:49:54+00:00Damien Georgedamien.p.george@gmail.com2016-12-21T23:49:54+00:00urn:sha1:c305ae32436e37327d33df979d57d9ac1fb822c1
The lexer is very mature and this debug function is no longer used. If
it's really needed one can uncomment it and recompile.

They are sugar for marking function as generator, "yield from"
and pep492 python "semantically equivalents" respectively.
@dpgeorge was the original author of this patch, but @pohmelie made
changes to implement `async for` and `async with`.
