Adding new package org-menu to nongnu elpa

Adding new package org-menu to nongnu elpa

Hello,

I’d like to offer my package org-menu to be included in nongnu elpa. I believe it has enough users to warrant making it easier to install

Kind regards,
Jan

Popularity is no precondition for a package to be added to NonGNU ELPA.
We can add the package, just consider the following comments and
suggestions:

Thanks for the feedback. Applied them. Some comments:

Throwing an error here now to keep the info about what snippet type was not found

> +;; You are require'ing yasnippet anyway, so there is no need to mess with autoloads

yasnippet should only be required dynamically if it is selected so the plugin can work without it being installed

Yes that should have been zero-width space. Fixed

This code used to be in lambdas and has since been moved into top-level functions. Calling them now

I’ve also changed the calls to deprecated functions you pointed out. This might break with older Emacs versions but those are supported as a best effort, only so let’s see if this fails for anyone or if compat.el handles this

Thanks!

Right, so it is wrong to autoload the function, as you do not want to
assume that they are loadable.

OK, btw. I remembered that you can simplify the eval-when-compile by
just writing

  ?\N{ZERO WIDTH SPACE}

.

Compat will probably not be of much use, as these were Org-specific
functions and Compat only provides core-Emacs functions.

Re: Adding new package org-menu to nongnu elpa

Hello Jan,

A Transient menu system for Org is definitely needed.  Have you 
discussed this on the Org mailing list?  Now that Transient is built in 
to Emacs, this is a feature that ought to be built in to Org.  And it 
ought to be standardized and modularized so that it can (eventually) be 
expanded and adapted to all parts of Org.

As well, I have a minor concern about the name: org-menu is so obviously 
the right name for the feature, that having it as a package on (non-) 
GNU ELPA would present a conflict, preventing Org from implementing the 
feature internally under that name.

So it would seem best if you could contribute the package upstream to 
Org; it could be an example and foundation for this work to grow on.

What do you think?

Yes the name is a good point. I don’t mind renaming it but I’m not sure to what. org-transient has been proposed but that one might just have the same issue. Proposals are very welcome! 

I’ve written a mail to emacs-orgmode@gnu.org <mailto:emacs-orgmode@gnu.org> ("Contributing org-menu (using transient) to Orgmode?”). Lets put adding this this on hold until that discussion finishes

[[[ To any NSA and FBI agents reading my email: please consider    ]]]
[[[ whether defending the US Constitution against all enemies,     ]]]
[[[ foreign or domestic, requires you to follow Snowden's example. ]]]

We try to aim to make Emacs coherent.  So when we consider adding to
Emacs a package that implemnts a new feature, it isn't just a matter
of how many users lke that feature.

There are several things we might want to do with a new feature
implemented as a eparate package:

* Add it to Emacs as written.
* Leave it out.
* Merge the code into related parts of Emacs for better integration.
* Reimplement the feature for better integration
* And someimes others.

Since I don't use Org mode, I don't have an opinion about what to do
in this case.  I'm simply reminding people to think about these
options for the functionaliy of org-menu, and make a good choice.
