Description

The operationId field of paths can have values which are not valid Elm identifiers. It seems that these values are used unmodified to produce Elm function names, meaning that the generator produces invalid Elm code.

This happens, for example, when operationId values contain "."s, as is common when using connexion.

Latest. Not sure.

Suggest a fix/enhancement

At least for my purposes, replacing '.' with '_' in the function names would do the trick. There may be more characters in valid operationId's which are invalid in Elm identifiers, though, so someone who knows the spec should find all translations that need to happen.
