New port: markdown-mode.el

[cubranic@…]

​Markdown-mode is an Emacs mode for editing text files using the Markdown formatting.

Question: do I need to include "universal_variant no" for a port that includes only Emacs-lisp code? In this case, it doesn't really make sense to install a universal variant, but I don't want to make it un-installable on a universal system.

No, because both "supported_archs noarch" and "use_configure no" already imply it.

[cubranic@…]

Thank you for the explanation. I attached the updated Portfile, with 'universal_variant no' removed. I also changed 'depends_build' to 'depends_lib', because Emacs is needed to both build and run the port.

Also, I entered the maintainer as 'nomaintainer', but would be happy to be one of course.

The checksums don't match for me. If the distfile is being generated on demand, that is likely the reason, and is a problem.

[cubranic@…]

You're correct. I downloaded two distfiles a few minutes apart, and while the unpacked contents are identical, the distfiles themselves are not binary indentical because of GZIP's timestamp in the header.

I changed the portfile to download the files available as static content from the project's web site. (Attached.)

I'm the author of markdown-mode and noticed this port submission recently. I'm a MacPorts user, but it had not occurred to me to make a Portfile for markdown-mode, so thanks for making one! I thought I'd provide some additional information in case it's helpful. Also, I'll note that there is a new version (1.9) since this Portfile was written.

The tarballs from the cgit interface are indeed automatically generated. In case they are useful, I've created "official" tarballs for each markdown-mode release which can be found, e.g., here:

​http://jblevins.org/projects/markdown-mode/markdown-mode-1.9.tar.gz

I'll keep adding these for each new stable release, so feel free to pull the distfile using the corresponding URL pattern. Of course, currently only the markdown-mode.el file is needed for installation, so it's fine to just download that file directly.

Although the stable version (used in the most recent Portfile attached above) has been on a long release cycle, I'd suggest that it be used for a primary package. If you still prefer to use the Git version (perhaps it could be called something like markdown-mode-git) then the latest .el file at the HEAD can be obtained directly here:

​http://jblevins.org/git/markdown-mode.git/plain/markdown-mode.el

Also, in case it helps with automating things, the 'stable' branch in the Git repository always tracks the last release, and each release has a tag of the form 'v1.8.1' or 'v1.9':

Finally, is it possible (or even necessary) to create an emacs_app variant? I used something like the following in the Portfile I wrote for the ESS package:

variant emacs_app description "If your Emacs is emacs-app" {
    depends_lib-append      port:emacs-app
    depends_lib-delete      port:emacs
    destroot.args-append    EMACS=/Applications/MacPorts/Emacs.app/Contents/MacOS/Emacs
    destroot.args-append    LISPDIR=${destroot}/Applications/MacPorts/Emacs.app/Contents/Resources/site-lisp/ess
}

Or is the emacs-app package already configured to look in ${destroot}${prefix}/share/emacs/site-lisp?

Thanks again for this port and please let me know if there's anything I can do to help.

Thank you Jason. I just noticed that markdown-mode 2.0 has been released. (Six months ago!) This will give me a kick in the pants to update the proposed portfile for the new version and with changes you recommended.

Portfile with the emacs_app variant and upgraded to version 2.0

[cubranic@…]

I updated the port to:

1. use markdown-mode 2.0
2. add an emacs_app variant

Note that the port still uses ${destroot}${prefix}/share/emacs/site-lisp as the LISPDIR because Emacs-app has this directory in its load path by default.
