As discussed in https://github.com/go-enry/go-enry/issues/54, this provides an
API for accessing a LanguageInfo struct which is populated with all the data
from the Linguist YAML source file. Functions are provided to access the
LanguageInfo by name or ID.
The other top-level functions like GetLanguageExtensions, GetLanguageGroup, etc.
could in principle be implemented using this structure, which would simplify the
code generation. But that would be a big change so I didn't do any of that.
Perhaps in the next major version something like that would make sense.
Prior to this change, GetLanguages collected all candidate languages from each
strategy to pass to the next strategy (without de-duplicating them). Linguist
only uses the previous strategy's candidates for the next strategy. Also, it
would overwrite languages with nil if a strategy returned that, so you could get
into a situation where you go from multiple languages to no language.
See the Ruby code for details: aad49acc06/lib/linguist.rb (L14-L49)
This addresses https://github.com/src-d/enry/issues/207 because GetLanguages
should not return all candidates detected, otherwise it would work differently
than Linguist.
The Linguist-defined language IDs are important to our use case because they are
used as database identifiers. This adds a new generator to extract the language
IDs into a map and uses that to implement GetLanguageID.
Because one language has the ID 0, there is no way to tell if a language name is
found or not. If desired, we could add this by returning (string, bool) from
GetLanguageID. But none of the other functions that take language names do this,
so I didn't want to introduce it here.
Even more reduces public API surface by
hiding un-used Classifier API for providing
a pre-trained classifier weights.

This allows to use a cached directory with linguist instead of cloning and speeds up the tests by -10s on my local machine.
