syl20bnr ebe4c60264 Revert "Defer packages by default using use-package-always-defer" 
This reverts commit 29c78ce841 and all other fixes
that have been made afterwards.

The motivation is that use-package is seen by many as a replacement for
`require`. Is use-package always defer the loading of packages then is breaks
this use case, this does not respect POLA so even if it was making Spacemacs
loading faster (up to 3s faster on some startup on my machine) we just cannot
use it, it would be irresponsible. Spacemacs should be easy to use, loading
performance will come with time but it is not a priority.

Purescript layer

/TakeV/spacemacs/media/commit/5b70ac500963390c0343bd78eafa6ead177f0405/layers/+lang/purescript/img/purescript-logo.png

Description

This layer provides basic Purescript editing support for spacemacs.

Features:

  • Syntax highlighting through purescript-mode
  • Automatic insert of imports through psc-ide-emacs
  • REPL through psci
  • Syntax checking through flycheck
  • Autocompletion through company

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 is 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
