Spacemacs configuration files and private layers

Spacemacs is a set of configurations available to power up your Emacs, the best text editor in the world. Spacemacs brings a modern interface, and many smart defaults, so you don't have to struggle to let your .emacs the way you want (although many like the challenge). Anyway, Spacemacs let you configure it the same old way, but based on layers, which makes things much more organized. By the way, Spacemacs even let Vim users to use keybindings they were used to, but with the power of Emacs.

This repository contains my .spacemacs file (named spacemacs.el) and some private layers.

Layers are in the private directory, and now they are:

• ess: This is a clone of the original Spacemacs ess layer (available at layers/+lang/ess), but it includes the following modifications:
  • Use R Coding Standards instead of Hadley's coding standards (the default in the official layer)
  • Create a new variable, ess-enable-smartparens, to allow smartparens package to be used in ess. It can be specified in your .spacemacs the same way as ess-enable-smart-equals (both are disabled by default)
• polymode: Creates a layer to install and configure polymode, adding support for R markdown (Rmd) files in Spacemacs. (Note that ess already supports Rnw files, and this is enabled by default in Spacemacs).
• funk: This is a layer to hold my personal (misc) functions and keybindings. It doesn't install any packages, just enable functions in funcs.el, and enables some keybindings setted in keybindings.el

These layers are enabled by moving them to ~/.emacs.d/private and adding these lines at dotspacemacs-configuration-layers in .spacemacs

ess
funk
polymode

Using elpy instead of python layer

To use Python in spacemacs, the default choice is to enable the python layer. This layer has by default the anaconda-mode, which has some particularities I personally don't like. An alternative is to use elpy, which is a completely different project, and is much more similar to the ESS layer for R.

To avoid conflicts, Spacemacs doesn't have an elpy layer by default. So, it is necessary to include this layer by yourself. To do this, you can copy this layer from this repository and place it under your ~/.emacs.d/private/ directory. After doin that, you can enable the elpy layer in your ~/.spacemacs.

Important: don't enable the python layer at the same time as the elpy layer as this may cause some conflicts. The elpy layer will be the only one responsible for handling python files and modes.

Maxima mode

There is no specific layer to enable the maxima-mode in Spacemacs. Anyway you can just follow the instructions from here and include the appropriate lines in user-config() section of your ~/.spacemacs.

Some details:

• Use .max extension
• M-x maxima-mode in the file
• M-x imaxima to open a Maxima terminal with the output rendered as LaTeX
• Basic commands:
  • C-c C-c: send a line
  • C-c *: open a commentary block
  • M-;: comment a line
