* py/lexer: Provide generic mp_lexer_new_from_file based on mp_reader.Damien George2016-11-16
| | | | | | If a port defines MICROPY_READER_POSIX or MICROPY_READER_FATFS then lexer.c now provides an implementation of mp_lexer_new_from_file using the mp_reader_new_file function.
* py: Be more specific with MP_DECLARE_CONST_FUN_OBJ macros.Damien George2016-10-21
| | | | | | | In order to have more fine-grained control over how builtin functions are constructed, the MP_DECLARE_CONST_FUN_OBJ macros are made more specific, with suffix of _0, _1, _2, _3, _VAR, _VAR_BETEEN or _KW. These names now match the MP_DEFINE_CONST_FUN_OBJ macros.
* teensy: Update to provide new mp_hal_pin_XXX functions following stmhal.Damien George2016-10-18
|
* py/vstr: Combine vstr_new_size with vstr_new since they are rarely used.Damien George2016-10-14
| | | | | | | Now there is just one function to allocate a new vstr, namely vstr_new (in addition to vstr_init etc). The caller of this function should know what initial size to allocate for the buffer, or at least have some policy or config option, instead of leaving it to a default (as it was before).
* all: Remove 'name' member from mp_obj_module_t struct.Damien George2016-09-22
| | | | One can instead lookup __name__ in the modules dict to get the value.
* Updated FROZEN_DIR support as per f28efa19713977a61395b19fec1fe501aeee4c0eDave Hylands2016-09-17

* py: Add MICROPY_USE_INTERNAL_PRINTF option, defaults to enabled.Delio Brignoli2016-09-05
| | | | | | | | This new config option allows to control whether MicroPython uses its own internal printf or not (if not, an external one should be linked in). Accompanying this new option is the inclusion of lib/utils/printf.c in the core list of source files, so that ports no longer need to include it themselves.
* teensy: Fix execution of frozen boot.py and main.pyDave Hylands2016-08-22
|
* ports: Remove typedef of machine_ptr_t, it's no longer needed.Damien George2016-08-15
| | | | | | This type was used only for the typedef of mp_obj_t, which is now defined by the object representation. So we can now remove this unused typedef, to simplify the mpconfigport.h file.
* cc3200, teensy: Remove broken malloc/free/realloc macro helpers.Damien George2016-08-02
| | | | | | These macros are broken and are anyway unused on these two ports. If they are ever needed in the future then their implementation can be taken from either stmhal (working macros in mpconfigport.h) or esp8266 (functions).
* teensy: Update the README with OSX specific information and tips.Georgia Reh2016-06-06
|
* cc3200, stmhal, teensy: Use pyhelp_print_obj function.Colin Hogben2016-04-25
| | | | | Update the help() implementations in the cc3200, stmhal and teensy ports to use the pyhelp_print_obj function.
* py: Add rules for automated extraction of qstrs from sources.Jan Čapek2016-04-16
| | | | | | | | | | | | | | | | | | | | | - add template rule that converts a specified source file into a qstring file - add special rule for generating a central header that contains all extracted/autogenerated strings - defined by QSTR_DEFS_COLLECTED variable. Each platform appends a list of sources that may contain qstrings into a new build variable: SRC_QSTR. Any autogenerated prerequisities are should be appened to SRC_QSTR_AUTO_DEPS variable. - remove most qstrings from py/qstrdefs, keep only qstrings that contain special characters - these cannot be easily detected in the sources without additional annotations - remove most manual qstrdefs, use qstrdef autogen for: py, cc3200, stmhal, teensy, unix, windows, pic16bit: - remove all micropython generic qstrdefs except for the special strings that contain special characters (e.g. /,+,<,> etc.) - remove all port specific qstrdefs except for special strings - append sources for qstr generation in platform makefiles (SRC_QSTR)
* py: Declare help, input, open builtins in core.Paul Sokolovsky2016-04-15
| | | | These are *defined* per-port, but why redeclare them again and again.
* py: Add ability to have frozen persistent bytecode from .mpy files.Damien George2016-04-13
| | | | | | | The config variable MICROPY_MODULE_FROZEN is now made of two separate parts: MICROPY_MODULE_FROZEN_STR and MICROPY_MODULE_FROZEN_MPY. This allows to have none, either or both of frozen strings and frozen mpy files (aka frozen bytecode).
* py/runtime: mp_stack_ctrl_init() should be called immediately on startup.Paul Sokolovsky2016-01-29
| | | | | | | | | Calling it from mp_init() is too late for some ports (like Unix), and leads to incomplete stack frame being captured, with following GC issues. So, now each port should call mp_stack_ctrl_init() on its own, ASAP after startup, and taking special precautions so it really was called before stack variables get allocated (because if such variable with a pointer is missed, it may lead to over-collecting (typical symptom is segfaulting)).
* py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*.Damien George2016-01-11
| | | | | | | | The first argument to the type.make_new method is naturally a uPy type, and all uses of this argument cast it directly to a pointer to a type structure. So it makes sense to just have it a pointer to a type from the very beginning (and a const pointer at that). This patch makes such a change, and removes all unnecessary casting to/from mp_obj_t.
* lib/utils: Add pyexec_frozen_module to load and execute frozen module.Damien George2015-12-26
| | | | | | This is a convenience function similar to pyexec_file. It should be used instead of raw mp_parse_compile_execute because the latter does not catch and report exceptions.
* stmhal: uart.any() function now returns number of bytes available.Ryan Shaw2015-11-30
|
* lib/utils/printf: Move from stmhal/ .Paul Sokolovsky2015-11-10
| | | | | This file contains various MicroPython-specific helper functions, so isn't good fit for lib/libc/.
* lib/pyexec: Move header pyexec.h from stmhal directory.Damien George2015-11-09
|
* teensy: Switch over to using frozen modules instead of memzipDave Hylands2015-11-04
| | | | | | | | | I left memzip in for the time being, so you can choose in the Makefile whether to USE_FROZEN or USE_MEMZIP. It looks like using frozen saves about 2472 bytes (using my set of 15 python files), mostly due to overheads in the zip file format.
* lib/memzip: Factor out memzip from teensy/ into lib/memzip.Dave Hylands2015-11-04
|
* stmhal: pyexec.c is common module, move to lib/utils/ .Paul Sokolovsky2015-10-31
|
* all: Add py/mphal.h and use it in all ports.Damien George2015-10-31
| | | | | | py/mphal.h contains declarations for generic mp_hal_XXX functions, such as stdio and delay/ticks, which ports should provide definitions for. A port will also provide mphalport.h with further HAL declarations.
* teensy: Switch from HAL_* to mp_hal_* functions.Paul Sokolovsky2015-10-29
|
* Makefiles: Remove duplicate object files when linking.Paul Sokolovsky2015-10-24
| | | | | | | | | | | Scenario: module1 depends on some common file from lib/, so specifies it in its SRC_MOD, and the same situation with module2, then common file from lib/ eventually ends up listed twice in $(OBJ), which leads to link errors. Make is equipped to deal with such situation easily, quoting the manual: "The value of $^ omits duplicate prerequisites, while $+ retains them and preserves their order." So, just use $^ consistently in all link targets.
* teensy: Update to compile with latest changes to stmhal Pin class.Damien George2015-10-19
|
* all: Make netutils.h available to all ports by default.Paul Sokolovsky2015-10-19
| | | | | Generally, ports should inherit INC from py.mk, append to it, not overwrite it. TODO: Likely should do the same for other vars too.
* Rename "Micro Python" to "MicroPython" in REPL, help, readme's and misc.Damien George2015-10-12
|
* py: Rename MP_BOOL() to mp_obj_new_bool() for consistency in naming.Paul Sokolovsky2015-10-11
|
* stmhal: Factor GPIO clock enable logic into mp_hal_gpio_clock_enable.Damien George2015-08-03
| | | | | | | | Extracted GPIO clock enable logic into mp_hal_gpio_clock_enable and called from anyplace which might need to use GPIO functions on ports other than A-D. Thanks to Dave Hylands for the patch.
* teensy: Add readinto and readlines qstrs.Damien George2015-05-13

* py: Overhaul and simplify printf/pfenv mechanism.Damien George2015-04-16
| | | | | | | | | | | | | | | | | | | | | | Previous to this patch the printing mechanism was a bit of a tangled mess. This patch attempts to consolidate printing into one interface. All (non-debug) printing now uses the mp_print* family of functions, mainly mp_printf. All these functions take an mp_print_t structure as their first argument, and this structure defines the printing backend through the "print_strn" function of said structure. Printing from the uPy core can reach the platform-defined print code via two paths: either through mp_sys_stdout_obj (defined pert port) in conjunction with mp_stream_write; or through the mp_plat_print structure which uses the MP_PLAT_PRINT_STRN macro to define how string are printed on the platform. The former is only used when MICROPY_PY_IO is defined. With this new scheme printing is generally more efficient (less layers to go through, less arguments to pass), and, given an mp_print_t* structure, one can call mp_print_str for efficiency instead of mp_printf("%s", ...). Code size is also reduced by around 200 bytes on Thumb2 archs.

* string0.c: Move from stmhal/ to lib/.Paul Sokolovsky2015-04-05
|
* stmhal: Make pybstdio usable by other ports, and use it.Damien George2015-02-13
| | | | | Now all ports can use pybstdio.c to provide sys.stdin/stdout/stderr, so long as they implement mp_hal_stdin_* and mp_hal_stdout_* functions.

* py: Change vstr_null_terminate -> vstr_null_terminated_str, returns str.Damien George2015-01-29
|
* py: Change vstr so that it doesn't null terminate buffer by default.Damien George2015-01-28
| | | | | | | | | This cleans up vstr so that it's a pure "variable buffer", and the user can decide whether they need to add a terminating null byte. In most places where vstr is used, the vstr did not need to be null terminated and so this patch saves code size, a tiny bit of RAM, and makes vstr usage more efficient. When null termination is needed it must be done explicitly using vstr_null_terminate.
* teensy: Update for readline module moved to lib/.Paul Sokolovsky2015-01-12

* py: Disable stack checking by default; enable on most ports.Damien George2015-01-09
|
* stmhal: Collect all root pointers together in 1 place.Damien George2015-01-07
| | | | | A GC in stmhal port now only scans true root pointers, not entire BSS. This reduces base GC time from 1700ms to 900ms.
* 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.
* teensy: Prefix includes with py/; remove need for -I../py.Damien George2015-01-01

* Makefiles: Support py/*.h includes per #1022.Paul Sokolovsky2014-12-27
|
* modsys: Add sys.print_exception(exc, file=sys.stdout) function.Paul Sokolovsky2014-12-08
| | | | | | | | | | | | The function is modeled after traceback.print_exception(), but unbloated, and put into existing module to save overhead on adding another module. Compliant traceback.print_exception() is intended to be implemented in micropython-lib in terms of sys.print_exception(). This change required refactoring mp_obj_print_exception() to take pfenv_t interface arguments. Addresses #751.
* Use MP_DEFINE_CONST_DICT macro to define module dicts.Damien George2014-11-29
| | | | | This is just a clean-up of the code. Generated code is exactly the same.
* stmhal: Reduce coupling between USB driver and readline.Damien George2014-11-27
| | | | | This makes it easier to re-use readline.c and pyexec.c from stmhal in other ports.
* ports: Define mp_off_t.Paul Sokolovsky2014-11-17
