duianto ee811f7b13 Unify packages list parentheses style 
problem:
some layer packages lists have the open and closing parentheses on the same line
as the first and last listed package, but most seem to have them on a separate
lines.

solution:
put the open and close parentheses on separate lines, except for lists with only
a single package, they are written on the same line as the variable name and
parentheses.

fix the lists indentation

Ocaml layer

/TakeV/spacemacs/media/commit/cc1764b2ad3a0bca2a3f89f7542288194ce7ad9b/layers/+lang/ocaml/img/ocaml.png

Description

This is a very basic layer for editing ocaml files.

Features:

Install

Layer

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

Using merlin for error reporting

By default flycheck-ocaml is used for error reporting when the syntax-checking layer is also enabled as this is common throughout spacemacs. You can disable this and switch back to merlin’s default error reporting method by adding flycheck-ocaml to your excluded packages list in .spacemacs:

  dotspacemacs-excluded-packages '(... flycheck-ocaml ... )

OPAM packages

This layer requires some opam packages:

  • merlin for auto-completion
  • utop
  • ocp-indent

To install them, use the following command:

  opam install merlin utop ocp-indent

Make sure opam is initialized and configured.

  opam init
  opam config setup -a

Key Bindings

Key Binding Description
SPC m = Indent buffer.
SPC m c c Compile
SPC m c p Check .merlin for errors
SPC m c r Refresh changed .cmis in merlin

SPC m e n Jump to next error
SPC m e N Jump back to previous error
SPC m g a Switch ML <-> MLI
SPC m g b Go back to the last position where the user did a locate
SPC m g g Locate the identifier under point (same window)
SPC m g G Locate the identifier under point (different window)
SPC m g o List occurrences for identifier under point
SPC m g l Prompt for identifier and locate
SPC m g i Prompt for module name and switch to ML file
SPC m g I Prompt for module name and switch to MLI file
SPC m h h Document the identifier under point
SPC m h t Highlight identifier under cursor and print its type
SPC m h T Prompt for expression and show its type
SPC m r d Case analyze the current enclosing

REPL (utop)

Key Binding Description
SPC m s b Send buffer to the REPL
SPC m s B Send buffer to the REPL and switch to the REPL in insert state
SPC m s i Start a REPL
SPC m s p Send phrase to the REPL
SPC m s P Send phrase to the REPL and switch to the REPL in insert state
