Do you mean, why doesn't DMD try to work around the problem
automatically
(e.g. by substituting/removing invalid characters in the module
identifier)? The error message answers your verbatim question.
- is a perfectly valid character in a file name, well on Posix compliant
systems anyway. The question is why D, aping Java, imposes restrictions
when there is no need.
Every character except '/' is valid in a file name. In D, the module name
must be a valid symbol, and also the name of the file you import to get
that module.
It's as simple as "don't name your files with non-valid symbol
characters." It's the way the language is designed, and if that's too
much of a burden, then don't use the language.
"test-file-name.d: Error: module test-file-name has non-identifier
characters in filename, use module declaration instead"
The real irritant for me is that the file in question has one function,
main, there is nothing to do with modules going on here.
Every compiled d file is a module, the compiler uses the file name if you
don't provide one. Note it is not advisable to name your modules
differently than the file name, because the module name is also used to
import the file. This means, if you named a file differently from a
module, importing the module will fail to find it. However, standalone
single-file programs should not be an issue.
This should compile:
test-file-name.d:
module testfilename;
void main()
{}
