🧨 EXCEPTION: undefined method `downcase' for Hash:Class

[tyler-macinnis]

With the latest pre-release gem, I'm getting a very strange error.

🧨 EXCEPTION: undefined method `downcase' for Hash:Class

I think it might be due to how I'm doing my defines, but I'm not sure.

:defines:
  :preprocess:
    :*:
      - STM32G071xx
      - TEST
  :test:
    :*:
      - STM32G071xx
      - TEST
    :analoguedataconverter:
      - REDEFINE_VREFINT_CAL_MACROS
    :porttimer:
      - REDEFINE_TIM_MACROS
    :vsd:
      - REDEFINE_UART_MACROS
  :release: []

Actually looking further I'm not sure what's causing it.

[mvandervoord]

This happens when you attempt to do anything? Does calling ceedling with ceedling -v=4 give any more information?

[tyler-macinnis]

Running ceedling clobber --log --verbosity=4 gives this

I'm not sure if it is defines though because I have another project with this define for its main project.yml.

:defines:
  :test:
    :*:
      - STM32H750xx
  :release: []

and it has a mixin with

:defines:
  :test:
    :*:
      - UNIT_TEST

and it is getting the same error

[mvandervoord]

I don't believe you're doing anything wrong. I think the recent updates that added validated have inadvertently created some problems. In this case, lines 230 and 237 in configurator_setup.rb both have config.class.downcase but really they should be config.class.to_s.downcase or perhaps config.class.inspect.

I'm not in a position to change it this moment, but you're welcome to tweak your own files and see if it helps.

[tyler-macinnis]

For the time being I'm just going to use the previous pre-release gem. But this should probably stay open until the issue is resolved.

[mkarlesky]

Hi, @tyler-macinnis. So sorry about this. The bug was a simple if perhaps baffling mistake in formatting an error message. It's fixed in the newest pre-release build.

Incidentally, there is a problem with your :defines: configuration. Only the :test context supports the advanced matchers. The other contexts apply a list of symbols to every file processed in that context. So, for instance, you can apply a set of symbols to the compilation of a specific test executable, but the symbols defined for a :release build apply to the compilation of the entire release artifact. Another user has already requested the ability be expanded from a test executable only to per file matching for release builds. Why doesn't it exist already? The mechanisms for test executable builds are quite a bit different than from other build operations.

Here is your configuration corrected (note changes to :preprocess).

:defines:
  :preprocess:
    - STM32G071xx
    - TEST
  :test:
    :*:
      - STM32G071xx
      - TEST
    :analoguedataconverter:
      - REDEFINE_VREFINT_CAL_MACROS
    :porttimer:
      - REDEFINE_TIM_MACROS
    :vsd:
      - REDEFINE_UART_MACROS
  :release: []

Your configuration motivated a bit more explicit error checking along with a more specific error message to handle matchers being used where only lists are supported.

[tyler-macinnis]

Are flags being changed as well?

I'm getting the following error

🪲 ERROR: :defines ↳ :gcov ↳ :compile entry '{:*=>["-Wno-int-to-pointer-cast", "-Wno-pointer-to-int-cast"]}' must be a list--matcher hashes only availalbe for the :test context (see docs for details)

[tyler-macinnis]

I'm assuming its as simple as

:flags:
  :test:
    :compile:
      :*:
        # Disable cast to/from pointer from/to integer of different size warnings
        # see https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html
        - -Wno-int-to-pointer-cast
        - -Wno-pointer-to-int-cast
  :gcov:
    :compile:
      # Disable cast to/from pointer from/to integer of different size warnings
      # see https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html
      - -Wno-int-to-pointer-cast
      - -Wno-pointer-to-int-cast

EDIT: Yes, that did it.

[mkarlesky]

@tyler-macinnis Yes, apart from the specifics of the top-level keys in :defines and :flags matcher rules and abilities are identical between them—namely, only symbols or command line arguments have the sophisticated option of being matched to a test executable within the containing :test context. The idea of matcher is not available outside of :test.

For test builds, you can do this:

:flags:
  :test:
    :compile:
      :*: # Match all test executables or use another matcher for a subset of test executables
        - -Wno-int-to-pointer-cast
        - -Wno-pointer-to-int-cast

or this:

:flags:
  :test:
    :compile: # Apply these flags to all test executable compilation
      - -Wno-int-to-pointer-cast
      - -Wno-pointer-to-int-cast

The latter is a simpler syntax than the former when you want the same flags applied for all test compilation. This latter syntax is also the only option for anything other than :test.

Unfortunately, a feature Ceedling does not yet have in its plugin structure is a way to connect plugin context to specific pipelines within the core of Ceedling. What this means is that :gcov should provide the same matching as :test, but Ceedling is not presently able to do this. Your flags in a coverage build cannot presently target individual test executable builds. With a planned overhaul of its plugin system, Ceedling will eventually be able to do so.
