Yonatan Goldschmidt 853aaa06f2 lib/mp-readline: Add word-based move/delete EMACS key sequences.
This commit adds backward-word, backward-kill-word, forward-word,
forward-kill-word sequences for the REPL, with bindings to Alt+F, Alt+B,
Alt+D and Alt+Backspace respectively.  It is disabled by default and can be
enabled via MICROPY_REPL_EMACS_WORDS_MOVE.

Further enabling MICROPY_REPL_EMACS_EXTRA_WORDS_MOVE adds extra bindings
for these new sequences: Ctrl+Right, Ctrl+Left and Ctrl+W.

The features are enabled on unix micropython-coverage and micropython-dev.

Yonatan Goldschmidt dce590c29d lib/mp-readline: Add an assert() to catch buffer overflows.
During readline development, this function may receive bad `pos` values.
It's easier to understand the assert() failing error than to have a "stack
smashing detected" message.

Alexander Steffen 55f33240f3 all: Use the name MicroPython consistently in comments
There were several different spellings of MicroPython present in comments,
when there should be only one.

Damien George e66fd56852 py/repl: Change mp_uint_t to size_t in repl helpers. 2017-07-04 23:44:54 +10:00
Damien George b6c7e4b143 all: Use full path name when including mp-readline/timeutils/netutils.
This follows the pattern of how all other headers are now included, and
makes it explicit where the header file comes from.  This patch also
removes -I options from Makefile's that specify the mp-readline/timeutils/
netutils directories, which are no longer needed.

Damien George b7ca945877 lib/mp-readline: Make it easy to exit auto-indent mode by pressing enter.
This patch allows you to stop auto-indent by pressing enter on a second
blank line.  Easier than having to use backspace, and prevents new users
from getting stuck in auto-indent mode.

Damien George 731f359292 all: Add py/mphal.h and use it in all ports.
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.

stijn 12fab63928 lib: Replace tabs with spaces in readline.c 2015-10-26 11:38:12 +00:00
Damien George f961456b29 lib/mp-readline: Add n_chars argument to mp_hal_erase_line_from_cursor.
If VT100 support is not available then a given implementation of
mp_hal_erase_line_from_cursor might need to know the number of characters
to erase.

This patch does not change generated code when VT100 is supported, since
compiler can optimise away the argument.

Damien George 46a1102852 repl: Add paste mode to friendly REPL, entered via CTRL-E.
Use CTRL-E to enter paste mode.  Prompt starts with "===" and accepts
all characters verbatim, echoing them back.  Only control characters are
CTRL-C which cancels the input and returns to normal REPL, and CTRL-D
which ends the input and executes it.  The input is executed as though
it were a file.  The input is not added to the prompt history.

Damien George 0af73014cc lib/mp-readline: Add auto-indent support.
4 spaces are added at start of line to match previous indent, and if
previous line ended in colon.

Backspace deletes 4 space if only spaces begin a line.

Configurable via MICROPY_REPL_AUTO_INDENT.  Disabled by default.

Tom Soulanille 7d588b0c7c lib/mp-readline: Add emacs-style control characters for cursor movement.
Disabled by default.  Adds 108 bytes to Thumb2 arch when enabled.

stijn 278d22ce8f lib/mp-readline: Allow overriding implementation of cursor functions
Default implementation uses VT100-style sequences which are not implemented
by all terminals out there

stijn 9a522dda6e lib/mp-readline: Add implementation for deleting a character
xterm and others use the ESC[~3 sequence when pressing the delete key

Damien George a1a2c411b2 py, readline: Add tab autocompletion for REPL.
Can complete names in the global namespace, as well as a chain of
attributes, eg pyb.Pin.board.<tab> will give a list of all board pins.

Costs 700 bytes ROM on Thumb2 arch, but greatly increases usability of
REPL prompt.

Damien George 0b32e50365 stmhal: Make pybstdio usable by other ports, and use it.
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.

Damien George 827b0f747b py: Change vstr_null_terminate -> vstr_null_terminated_str, returns str. 2015-01-29 13:57:23 +00:00
Damien George 0d3cb6726d py: Change vstr so that it doesn't null terminate buffer by default.
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.

Paul Sokolovsky 3f9f9cac75 lib/mp-readline: Refactor to support coroutine/event-driven usage.
readline_process_char() can be fed character by character, for example,
received from external event loop. This will allow to integrate MicroPython
into cooperative multitasking systems.
