README.md

(for use with Emacs 25.x)

Quick start guide...

Fork this repo, and then add it as upstream.

git clone [your-fork]

git remote add upstream https://github.com/ocodo/emacs.d

You can add packages from Elpa, and customisations to local/init.el, these will run after init.el has finished.

Note: extended downstream customisation options are being added soon.

Another Note: your local color theme choice will not be overwritten by updates from upstream - pick one with M-x helm-themes

Updating from upstream

git pull --all

Make sure we're in our own master branch

git checkout master

Grab all the upstream changes

git rebase upstream/master

If you've modified shared resources, you'll have conflicts to deal with.

If you wish to maintain upstream complete update compatibility, only update your ./local/.. (which is ignored by git, so you can make it a separate git repository if you want to.)

I suggest you break away from upstream as soon as you are comfortable installing your own packages.

Local Config

This config is intended to be used to make Emacs a highly useful editor, and give it some minimalist UI touches. (no Menu, no Toolbar, etc.) It also includes a huge library of pre-installed extensions.

To add localised config, create and use the folder ./local/

Add general config to ./local/init.el

Customize will write to (and load from) ./local/custom.el if you add it before startup.

Copy ./custom/custom.el to ./local/custom.el if you want to start from the same state as the general config.

Package/Feature configuration

The biggest feature of this config is the use of Nginx / Apache Server style split configuration.

Feature/Package configuration is set in /_configs and enabled by symlinking to _activated.

Currently this is only supported for the centralized repo, so changes are propagated unless you fork.

Using a git rebase / upstream style of updating would be ok, but you will risk clobbering your own changes.

I am planning to add the ability to apply similar configuration via a local/init

Local Color Theme Persistence

You color-theme selection is always stored locally, in ~/.emacs-theme - initially this will be non-existent or empty.

After first running Emacs with this config, simply run:

M-x helm-themes

Now select a theme from the list.

Your selection will be saved, and untouched by upstream.

Handy resources for getting more out of Emacs

This deserves special mention. Tuhdo has done great work here, and managed to cover many many modern extensions to Emacs. Reading the entire set of articles will give you a lot of valuable info. Especially when it comes to making Emacs feel like a modern editor.

This config, has most of the extensions mentiond installed already, and every week (or even more frequently) they're updated in this upstream.

And of course, the official emacs tour and manual...

Invaluable reading

As you may know, Lisp is the backbone of Emacs, and although emacs-lisp isn't quite up there with Common Lisp or Clojure, it's still extremely powerful as a programming tool.

If you have a chance, read Paul Graham's OnLisp, it is the most extraordinary book, when it comes to revealing the true power of Lisp it's in a class of it's own.

It's available as a free PDF download from http://www.paulgraham.com/onlisp.html

Still don't know what Emacs actually is?

Emacs is often jokingly called an OS, really though, it's a Lisp programming scratchpad, quite similar to the old Symbolics Lisp Machines, Smalltalk, IPython, IJulia etc. albeit without much attention paid to GUI features.

Just 30+ years focussed on editing features... thousands of them, just take a look at M-x package-list-packages.

I've added scores of editing features tailored to my own tastes, I'm sure you'll find it relatively easy to add your own once you get over parenthesiophobia (the fear of Lisp.)

iTerm2 OSX Semantic History

If you use Iterm2, you may be a little sad that there's no Emacs entry in the Open With Editor.. "Semantic History" option. (If you don't know of it, you'll find it in Advanced preferences)

There's a few solutions dotted around in different gists and other places around the web. Personally I didn't have too much luck with the scripts I found, so I've added one to my config which works better for me.

Set Semantic History to Run coprocess... and paste in the following:

~/.emacs.d/bin/iterm-emacsclient +\2 \1

Then you're able to Cmd click on filenames in iTerm2 and it will open up an Emacs buffer (or start Emacs from /Applications)

To open the file at line number. Cmd clicking on a filename printed in the terminal with a number suffix, e.g. README.md:130 would open README.md at line 130.

git elpa

I've included a utility to assist with keeping my elpa packages committed individually when they're updated.

I keep versioned copies of elpa packages for several reasons.

  • If a package suddenly disappears, I don't lose it.
  • If gnu elpa or melpa are down for any reason, I have multiple locations from which I can clone a full install of my .emacs.d.
  • If I have an issue with a package, it's very easy for me to rollback to a specific version.
    • Thanks to my new git elpa utility, it's now even easier. I can cherry pick a single version of a package, without external dependency on the package's own repo, etc. I can see the history of the package's main elisp file locally too.
  • If I wish to patch a package directly (obviously better to use defadvice, but that point aside) I can, however unlikely that may be.
  • bisecting the config is MUCH easier so bug discovery and fixing is improved.

Git elpa usage

After doing a package install / upgrade from within Emacs, git-elpa (~/.emacs.d/bin/git-elpa) will be able to list and commit the newly added/upgraded packages.

  • List all new / upgraded packages

    git elpa -l
    
  • Commit a single package addition / upgrade

    git elpa -c PACKAGENAME
    

    PACKAGENAME would be the name of the package without version info or .el file extension etc.

    e.g.

    git elpa -c magit
    

    To perform the commit of the last magit version upgrade, add new files and remove old ones (from the git index) and commit them with an auto-generated commit message

  • Commit all new / upgraded packages

    git elpa -a
    

    All packages will be commited in individual git commits, using auto-generated commit messages.
