As of new OPAM (OCaml package manager) v2.1, `opam config var share` is
no longer supported. Instead, the syntax is `opam var share`. To allow
both, this checks first with the new syntax, then if that doesn't work,
the old is tried. If neither produce any output, it fails as normal.
edit: Fix formatting.
We should always define the 2 flycheck initialization functions:
Spacemacs will call them as needed only when enabling syntax checking.
Previously flycheck wasn't getting activated at all.
Only activate `flycheck-ocaml` when a `.merlin` file is present.
It would work when there isn't but there is a high chance that you will
get a lot of errors displayed because it could not find any of the used
modules (`.merlin` specifies module paths).
OCaml projects usually do have a `.merlin` file
(either hand crafted or generated by the build system).

lang/ocaml: add merlin-eldoc and merlin-imenu support
This displays the type and documentation of thing under point
and highlights occurrences automatically when idle. Could be achieved by appropriate use of
keyboard shortcuts already set up by this module.
However `merlin-eldoc` can also display the expected type of function call parameters,
which merlin itself wouldn't.
`merlin-imenu` allows jumping to top level modules/functions/etc. bound
by default to `SPC j i`.

Dune is a popular build-tool for OCaml projects, the `dune` package adds:
- Adds syntax highlighting
- Template insertion
- Some testing/compilation functions
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
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.
This commit uses process-lines instead of shell-command-to-string, as
seen in ocaml/merlin#547.
This fixes an issue on Windows where the external command fails,
resulting in a broken load-path.
Currently the ocaml layer requires opam in order to work. However
opam is only really required for an easy installation of the
required ocaml binaries. The only place where opam is used
instead is to add the merlin files of the merlin installed
via opam instead of the merlin files from melp.
This commit introduces a fallback if opam is not installed but
ocamlmerlin is installed, since the melpa package of merlin
is already installed through packages.
spacemacs/add-flycheck-hook was not really hooking anything, change the name
to better reflect what it does.
Also changed the push for a add-to-list to avoid duplicates.
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.
Hook semantic is to be used with run-hooks API and run all hooks
sequentially, jump list semantic is different since the running
functions are not guaranteed to be executed so we prefer using regular
list API to manage jump-lists.
- Add option to disable by default
- Use local-vars hook to allow per-project enable/disable
- Don’t enable helm-gtags-mode (no need)
- Move emacs bindings from helm-gtags-mode-map to ggtags-mode-map
This commit defines:
- spacemacs-default-jump-handlers: a list of functions that can jump to
definition in ALL modes.
- spacemacs-jump-handlers-MODE: a list of functions that can jump to
definition in MODE.
- spacemacs-jump-handlers: a buffer-local list of functions that can
jump to definition. This is made up of the values of the two previous
variables whenever a given major mode is activated.
- spacemacs/jump-to-definition: a function that tries each function in
spacemacs-jump-handlers in order, and stops when one of them takes us
somewhere new.
- spacemacs|define-jump-handlers: a macro that
* defines spacemacs-jump-handlers-MODE, possibly filled with initial
functions
* defines a function that is added to the hook of the given MODE
* binds “SPC m g g” of that MODE to spacemacs/jump-to-definition
This is an attempt to harmonize all the different approaches to jumping.
Specifically,
- Existing intelligent jump packages that work for only a single mode
should go to the beginning of spacemacs-jump-handlers-MODE. E.g.
anaconda for python, ensime for scala, etc.
- Packages like gtags that work for several modes (but potentially not
all) and which is dumber than the intelligent jumpers should go the
the END of spacemacs-jump-handlers-MODE.
- Packages like dumb-jump that work for all modes should go to
spacemacs-default-jump-handlers.
In all cases the order of the jump handlers in each list should be from
most to least intelligent.
