Having a micropython.const identity function, and writing "from micropython
import const" at the start of scripts that use the const feature, allows to
write scripts which are compatible with CPython, and with uPy builds that
don't include const optimisation.
This patch adds such a function and updates the tests to do the import.
py/parse: Treat constants that start with underscore as private.2016-06-06T16:28:32+00:00Damien Georgedamien.p.george@gmail.com2016-06-06T16:28:32+00:00urn:sha1:b1533c43669c037d04c87d1756355cdc8edd5e0a
Assignments of the form "_id = const(value)" are treated as private
(following a similar CPython convention) and code is no longer emitted
for the assignment to a global variable.
See issue #2111.
py, compiler: Add basic support for A=const(123).2014-05-08T15:58:39+00:00Damien Georgedamien.p.george@gmail.com2014-05-08T15:58:39+00:00urn:sha1:ffae48d7507d398806bd935b054b7ca19bc01161
You can now do:
X = const(123)
Y = const(456 + X)
and the compiler will replace X and Y with their values.
See discussion in issue #266 and issue #573.
