customizing Info-default-directory-list

[martin-volf]

The change introduced with fixing #2118 causes that my customization of Info-default-directory-list does not work any longer. What's the expected way of doing that? The function info-initialize is called from helm-info.el early on, before my init.el file is read, and as a result, any changes done to Info-default-directory-list done in init.el are ignored.

How is this possible that helm-info is loaded before your init file?

It is not, my bad. Something is calling info-initialize and the only reference I found is in helm-info, but that is indeed loaded long after the init file.

info-initialize is not modifying Info-default-directory-list, only Info-directory-list. If Info-directory-list is already feeded, it doesn't touch it, otherwise it tries to give it a default value according to INFOPATH if found and finally fallback to (Info-default-dirs). So I can't see for now in what Helm is involved here. Perhaps you can give me more infos on how you are setting up your infos directories?

(Info-default-dirs).

Right, so when something calls info-initialize, any further changes to Info-default-directory-list are ignored. I am adding custom directories to that default list in my init file and after a larger emacs and emacs-packages update this stopped to have any effect.

So I can't see for now in what Helm is involved here.

Helm is not involved at all - I saw the reference to info-initialize in helm-info and concluded that this was the problem. But that conclusion was too quick; as you wrote, helm-info is loaded much later than my init file. Sorry for the confusion.

Info-default-directory-list and Info-directory-list are confusing, my understanding is that Info-default-directory-list should not be a custom variable, its purpose is to handle a list of defaults Emacs itself sets on startup. Here I only modify Info-directory-list from my init file and after that helm is loaded (in this case info-initialize is a noop).

No problems.

I think this warrants an M-x report-emacs-bug. Martin, could you maybe do that?

I see that Info-directory-list is feeded in package.el, so if user set Info-default-directory-list after package initialize (which is the way to do) Info-default-directory-list will be ignored.

For the sake of completeness: looks like Info-default-directory-list should not be used the way I did it, and its comment says that, in a sense. I should have been using Info-additional-directory-list instead - that works without problems. The documentation in this respect is a bit hard to find (at least for the likes of me), but it is there.

Do you also think that the user should just customize `Info-additional-directory-list`? Seems that this is indeed the option one should normally change.
