* all: Use the name MicroPython consistently in commentsAlexander Steffen2017-07-31
| | | | | There were several different spellings of MicroPython present in comments, when there should be only one.
* all: Unify header guard usage.Alexander Steffen2017-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.Damien George2017-02-17

* py/lexer: Simplify handling of line-continuation error.Damien George2017-02-17
| | | | | | | | | 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.Damien George2017-02-17
| | | | | | | | | | | | 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.Damien George2016-12-22
| | | | | The lexer is very mature and this debug function is no longer used. If it's really needed one can uncomment it and recompile.
* py/lexer: Make lexer use an mp_reader as its source.Damien George2016-11-16

* py: add async/await/async for/async with syntaxpohmelie2016-04-13
| | | | | | | | 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`.
* unix: Allow to cat a script into stdin from the command line.Damien George2015-06-04
| | | | See issue #1306.
* py: Allow to compile with extra warnings (sign-compare, unused-param).Damien George2015-03-19

* py: Parse big-int/float/imag constants directly in parser.Damien George2015-02-08
| | | | | | | | | Previous to this patch, a big-int, float or imag constant was interned (made into a qstr) and then parsed at runtime to create an object each time it was needed. This is wasteful in RAM and not efficient. Now, these constants are parsed straight away in the parser and turned into objects. This allows constants with large numbers of digits (so addresses issue #1103) and takes us a step closer to #722.
* py: Put all global state together in state structures.Damien George2015-01-07
| | | | | | This patch consolidates all global variables in py/ core into one place, in a global structure. Root pointers are all located together to make GC tracing easier and more efficient.
* py: Move to guarded includes, everywhere in py/ core.Damien George2015-01-01
| | | | Addresses issue #1022.
* py: Move to guarded includes for compile.h and related headers.Paul Sokolovsky2014-12-27
|
* py: Optimise lexer by exposing lexer type.Damien George2014-12-05
| | | | | | | | | mp_lexer_t type is exposed, mp_token_t type is removed, and simple lexer functions (like checking current token kind) are now inlined. This saves 784 bytes ROM on 32-bit unix, 348 bytes on stmhal, and 460 bytes on bare-arm. It also saves a tiny bit of RAM since mp_lexer_t is a bit smaller. Also will run a bit more efficiently.
* py: Change lexer stream API to return bytes not chars.Damien George2014-07-30
| | | | Lexer is now 8-bit clean inside strings.
* lexer: Convert type (u)int to mp_(u)int_t.Damien George2014-07-03
|
* py: Instead of having "debug on" var, have "optimization level" var.Paul Sokolovsky2014-06-03
| | | | | This allows to have multiple "optimization" levels (CPython has two (-OO removes docstrings), we can have more).
* Add license header to (almost) all files.Damien George2014-05-03
| | | | | | | Blanket wide to all .c and .h files. Some files originating from ST are difficult to deal with (license wise) so it was left out of those. Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.
* Search paths properly on import and execute __init__.py if it exists.Damien George2014-02-05
|
* Implement mp_parse_node_free; print properly repr(string).Damien George2014-01-25
|
* Add source file name and line number to error messages.Damien George2014-01-18
| | | | | Byte code has a map from byte-code offset to source-code line number, used to give better error messages.
* Convert parse errors to exceptions.Damien George2014-01-15
| | | | | Parser no longer prints an error, but instead returns an exception ID and message.
* py: Improve memory management for parser; add lexer error for bad line cont.Damien George2014-01-12
|
* Move lexerstr to main py directory (everyone uses it).Damien George2014-01-08
|
* Add ellipsis object.Damien George2014-01-04
|
* Basic implementation of import.Damien George2014-01-03
| | | | | | import works for simple cases. Still work to do on finding the right script, and setting globals/locals correctly when running an imported function.
* Change object representation from 1 big union to individual structs.Damien2013-12-21
| | | | | | | | | | A big change. Micro Python objects are allocated as individual structs with the first element being a pointer to the type information (which is itself an object). This scheme follows CPython. Much more flexible, not necessarily slower, uses same heap memory, and can allocate objects statically. Also change name prefix, from py_ to mp_ (mp for Micro Python).
