syl20bnr 74fdbb6795 Refactor and simplify company backends declaration
Enabling a company backend for a specific mode was a tedious tasks with code
scattered at different locations, one for local variable definitions, one for
company hook function definitions and another where the backends were pushed to
the local variables (which was problematic, since we ended up pushing the same
backends over and over again with `SPC f e R`, pushes have been replaced by
add-to-list calls in the new macro).

All these steps are now put together at one place with the new macro
spacemacs|add-company-backends, check its docstring for more info on its
arguments.

This macro also allows to define arbitrary buffer local variables to tune
company for specific modes (similar to layer variables via a keyword :variables)

The code related to company backends management has been moved to the
auto-completion layer in the funcs.el file. A nice side effect of this move is
that it enforces correct encapsulation of company backends related code. We can
now easily detect if there is some configuration leakage when the
auto-completion layer is not used. But we loose macro expansion at file loading
time (not sue it is a big concern though).

The function spacemacs|enable-auto-complete was never used so it has been
deleted which led to the deletion of the now empty file core-auto-completion.el.

The example in LAYERS.org regarding auto-completion is now out of date and has
been deleted. An example to setup auto-completion is provided in the README.org
file of the auto-completion layer.

Purescript layer

/TakeV/spacemacs/media/commit/74fdbb6795018a93a665fa2c417589cd4cbd51fc/layers/+lang/purescript/img/purescript-logo.png

Description

This layer provides basic Purescript editing support for spacemacs thanks to the following packages:

Install

To use this configuration layer, add it to your ~/.spacemacs. You will need to add purescript to the existing dotspacemacs-configuration-layers list in this file.

You'll also need to make sure the PureScript compiler and its associated binaries (psc-ide-server, psci,…) are on your path. Installation instructions can be found here.

Configuration

Add import on completion

Set purescript-add-import-on-completion to nil to make psc-ide stop adding imports on completion. Default value it t.

Error popup

If you set purescript-enable-rebuild-on-save to non-nil, you will get a popup buffer showing you your current warnings/errors one at a time. This is primarily meant as an alternative to using flycheck. Default value is nil.

Key bindings

Purescript

Imports

Key Binding Description
SPC m i = Format imports
SPC m i \ Return to where you were editing before navigating to imports
SPC m i a Align imports
SPC m i n Navigate to the imports

psc-ide

psc-ide command are available under SPC m m:

Key Binding Description
SPC m m s Start psc-ide-server
SPC m m l Load definitions for the modules inside your project
SPC m h t Show type at point
SPC m g g Goto definition for identifier at point
SPC m m b Rebuilds the current file and displays any warnings or errors
SPC m m i a Add an import for the identifier at the current cursor position
SPC m m i s Inserts a suggestion for the warning/error at the current cursor position
SPC m m t Add a new clause for the function signature at point
SPC m m c s Casesplits on the identifier at the current cursor position
SPC m m q Quit the current psc-ide-server
SPC m m L Load a specific module (This is mostly used for troubleshooting)

REPL

psci provides a very basic REPL for purescript. The following key bindings are available:

Key Binding Description
SPC m s b Equivalent of :m /path/to/current/module/file.purs - Load <file> for importing
SPC m s i Launch a psci console buffer
SPC m s m Equivalent of :i your.current.module.name - Import <module> for use in PSCI
SPC m s p Load or reload files defined in the project file .psci
