package lacks a "Version" or "Package-Version" header

[k69]

Please, add version header in leuven-theme.el like there for ability to install your super theme by emacs package system and to add this package to the melpa archive.

Hello k69. Thanks for your interest in my color theme.

I've already added a version number.

I still need to contribute my package to MELPA, for example (BTW, why that one in particular? I'm not using any package manager yet).

Though, note as well that Emacs Leuven has been added in the "to be" Emacs 24.4 -- it is already in the Emacs 24 dev branch.

Best regards, Fabrice

Hello Fabrice.

Sorry, I made a mistake. It is not a must to have a "Version" header in package, if it will be built by MELPA, because MELPA adds itself generated "Version" header and places initial version to the "X-Original-Version" header if necessary. Problem was in my emacs, package-install-file (emacs function for install package from file, incidentally for check package, that was generated from MELPA recipe, before this recipe will be added to the MELPA on internet) always tells that selected package lacks a "Version" or "Package-Version" header, even if package has a "Version" header. But package-install-from-buffer (which does same as package-install-file, but gets package content from the buffer instead of getting it from the selected file) work well.

And the answer to your question is below. There are two common package managers in emacs:

• The first one is el-get, which according to recipes fetches emacs plugins from their initial places (from emacs wiki, git, svn, cvs, hg, bzr, darcs...), builds them and loads into emacs. Its advantages are that it has many recipes (your color theme is included already (not by me)) and this recipes are made and added easily. But to use it you should have additional installed software on your computer such different SCM...
• The second one is inside emacs package manager (you can read about here and here). It is simple, package for it consists of one file (like your leuven-theme.el) or of a tar archive with plugin files and some info about package in el file. There are several package archives on the internet, but MELPA is special one. It uses recipes (like el-get) and fetches files and builds packages on its server. Peoples often call it server-side el-get.

It is good, that your theme has been added in 24.4. But from MELPA people can get fresh version of it any time.

Thank you for "leuven", for quick and pleasant response. Best regards, Danila.
