* Description
|
|
|
|
This layer provides basic Purescript editing support for spacemacs
|
|
thanks to the following packages:
|
|
- [[https://github.com/dysinger/purescript-mode][purescript-mode]]
|
|
- [[https://github.com/ardumont/emacs-psci][psci]]
|
|
- [[https://github.com/epost/psc-ide-emacs][psc-ide-emacs]]
|
|
|
|
* 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 [[http://www.purescript.org/download/][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.
