Function	Description
ExistingFileWordExp	Checks whether file exists (after expansion)

std::string alice::ExistingFileWordExp(const std::string &filename)

Checks whether file exists (after expansion)

Before checking whether the file exists, tilde characters for home directories and environment variables are expanded (using wordexp).

In Windows this method is just forwarding to CLI::EistingFile and does not perform any substitution.

Camel case convention for this function is intentional to match the convention of CLI11, since this function is used when declaring CLI options.

Parameters

• filename: Filename
