Description

This layer adds support for the Idris language to Spacemacs.

Features:

• Syntax highlighting
• Syntax checking via flycheck
• Integration of the Idris REPL
• Integration of the Idris build system

Install

Layer

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

Idris

Idris can be installed using Haskell's cabal:

  cabal install idris

Binaries are also available for some platforms at https://www.idris-lang.org/download/

Key bindings

Shorthands

Several (but not all) of the evil-leader shorthands that idris-mode provides are reproduced under the local leader.

Key binding	Description
SPC m c	Case split the pattern variable under point, or make it into a case expression.
SPC m d	Create an initial pattern match clause for a type declaration.
SPC m l	Extract lemma from hole
SPC m p	Attempt to solve a metavariable automatically.
SPC m r	Load current buffer into Idris.
SPC m t	Get the type for the identifier under point.
SPC m w	Add a with block for the pattern-match clause under point.

Interactive editing

Key binding	Description
SPC m i a	Attempt to solve a metavariable automatically.
SPC m i c	Case split the pattern variable under point, or make it into a case expression.
SPC m i e	Extract a metavariable or provisional definition name to an explicit top level definition.
SPC m i m	Add missing pattern-match cases to an existing definition.
SPC m i r	Refine by name, without recursive proof search.
SPC m i s	Create an initial pattern match clause for a type declaration.
SPC m i w	Add a with block for the pattern-match clause under point.

Documentation

Key binding	Description
SPC m h a	Search the documentation for a string.
SPC m h d	Search the documentation for the name under point.
SPC m h s	Search the documentation regarding a particular type.
SPC m h t	Get the type for the identifier under point.

REPL

Key binding	Description
SPC m s b	Load the current buffer into Idris.
SPC m s B	Load the current buffer into Idris and switch to REPL in insert state
SPC m s i	Start Idris inferior process
SPC m s n	Extend the region to be loaded one line at a time.
SPC m s N	Extend the region to be loaded one line at a time and switch to REPL in insert state
SPC m s p	Contract the region to be loaded one line at a time
SPC m s P	Contract the region to be loaded one line at a time and switch to REPL in insert state
SPC m s s	Switch to REPL buffer
SPC m s q	Quit the Idris process

Active term manipulations

Key binding	Description
SPC m m c	Show the core language for the term at point.
SPC m m i	Show implicits for the term at point.
SPC m m h	Hide implicits for the term at point.
SPC m m n	Normalize the term at point.

Build system

Key binding	Description
SPC m b c	Build the package.
SPC m b C	Clean the package, removing .ibc files
SPC m b i	Install the package to the user's repository, building first if necessary.
SPC m b p	Open package file.

When inside a package file, you can insert a field with SPC m f.
