My Dot Files

This is intended to be a collection of the dot files I use to setup my work environment in, primarily for Linux.

Initially, I only have my Emacs setup here.

Emacs

I primarily work with C++ development in CMake projects under Git version control, where more often than not the supporting tools are written in Python. Thus, my Emacs configuration is inclined to primarily support C++ and Python development, as well as supporting my recently started journey into literate programming using the Babel Project, based on org-mode.

Before DOOM

Prior to using the configuration tracked in this repository, I was using the configuration covered in my dfrib/emacs_setup repository, which was a standard Emacs custom configuration centered around cmake-ide and rtags for setting up C++ IDE-like Emacs features.

The DOOM Era

I have since migrated to use a non-evil configuration of DOOM Emacs, moreover switching out cmake-ide and rtags in favour of ccls for my C++ IDE-like Emacs feature needs.

My non-evil configuration was initially forked from UndeadKernel/emacs_doom_private, see the actual fork for the history prior to the creation of this repository.

Similarly to the setup instructions as the dfrib/emacs_setup repository, below follows a summary of the pre-requisites for making use of my Emacs configuration.

Pre-requisites (Assuming Ubuntu)

CCLS

As is described in the ccls wiki, prior to building the ccls language server, the are some pre-requisites.

Install GCC, version >= 7.3 (or higher, if required by CMake installation)

For details: see How do I use the latest GCC on Ubuntu?

Add the Toolchain Test Builds PPA:

$ sudo add-apt-repository ppa:ubuntu-toolchain-r/test
$ sudo apt-get update

Install e.g. GCC 8 and add the gcc-8 and g++8 alternatives to the system:

$ sudo apt-get install gcc-8 g++-8
$ sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-8 60 --slave /usr/bin/g++ g++ /usr/bin/g++-8

Use sudo update-alternatives --config gcc to configure which gcc to use as default, in case you have other versions installed.

Install CMake, version >= 3.8

Make sure you have a recent GCC installed (see above), as building recent CMakes places pre-requisites on GCC version.

The default version provided by e.g. Ubuntus package manager is usually ancient, so remove that:

$ sudo apt remove cmake
$ sudo apt purge --auto-remove cmake

Download and unpack a recent version from CMake's webpage, noting that it is essential that you keep the unpacked folder for later, to allow uninstalling the CMake you will now install from source (see this Q&A). E.g., to download CMake 3.12.3 (Linux) to your (existing) ~opensource directory and thereafter unpack it:

$ cd ~/opensource
$ wget https://cmake.org/files/v3.12/cmake-3.12.3.tar.gz
$ tar -xzvf cmake-3.12.3.tar.gz

Install the extracted source:

$ cd ~/opensource/cmake-3.12.3
$ ./bootstrap
$ make -j4
$ sudo make install

This will be installed under /usr/local/bin/, so you might want to close your current terminal, and in a new terminal, try:

$ cmake --version # 3.12.3 ?

Recall from above: that if you'd like to uninstall this particular CMake version, you need to return to the corresponding source and uninstall from there:

$ cd ~/opensource/cmake-3.12.3
$ sudo make uninstall

Build CCLS

(Mostly extracted from CCLS: Getting Started)

Given that the steps above was successful, you are now ready to build the language server. I usually place the project in ~opensource.

$ cd ~/opensource
$ git clone https://github.com/MaskRay/ccls --depth=1
$ cd ccls
$ git submodule update --init
$ cmake -H. -BRelease # This downloads prebuilt clang+llvm from releases.llvm.org
$ cmake --build Release

Installing DOOM Emacs

Personal settings

Clone this repository and place a symlink ~/.doom.d to the emacs/.doom.d folder of this repository.

E.g.:

$ cd ~/opensource
$ git clone https://github.com/dfrib/dot-files.git
$ ln -s ~/opensource/dot-files/emacs/.doom.d ~/.doom.d

DOOM Emacs

Taking parts of Quick Start from develop branch of hlissner/doom-emacs

$ git clone https://github.com/hlissner/doom-emacs ~/.emacs.d
$ cd ~/.emacs.d
$ git checkout develop
$ ./bin/doom quickstart

Every time you modify your ~/.doom.em/init.el, make sure to run:

$ ~/.emacs.d/bin/doom refresh

That should be it!
