Using dot . in PROGNAME causes unexpected behavior during building

[MohammedNoureldin]

I want to rename the output firmware.bin file according to the example supplied by the official documentation.

platformio.ini:

[env:env_custom_prog_name]
platform = espressif8266
board = nodemcuv2
framework = arduino
build_flags = -D VERSION=13
extra_scripts = pre:extra_script.py

extra_script.py:

Import("env")

my_flags = env.ParseFlags(env['BUILD_FLAGS'])
defines = {k: v for (k, v) in my_flags.get("CPPDEFINES")}
# print(defines)

env.Replace(PROGNAME="firmware_%s" % defines.get("VERSION"))

The default empty main.cpp file is sufficient to reproduce the problem.

The previous default example will work. However, as soon as I use the PROGNAME 1.2.3+4 (which includes dots), the program does not build properly anymore. It removes the extension of the ,elf file, and the partitions.bin is missing (which causes fail to upload).

So in other words, for the example above, the problem is reproducible as soon as I use the following semantic VERSION instead of 13: 1.2.3+4

The problem happens exactly because there is a dot inside the the PROGNAME. Could you please check it?

@ivankravets shouldn't this be labeled as bug?

Please re-test with pio upgrade --dev.

@ivankravets @valeros This seems to be working now! Thanks a lot to you both!
