# E-scripts on ocaml.
#
# Note 1: use the eev command (defined in eev.el) and the
# ee alias (in my .zshrc) to execute parts of this file.
# Executing this file as a whole makes no sense.
# An introduction to eev can be found here:
#
#   (find-eev-quick-intro)
#   http://angg.twu.net/eev-intros/find-eev-quick-intro.html
#
# Note 2: be VERY careful and make sure you understand what
# you're doing.
#
# Note 3: If you use a shell other than zsh things like |&
# and the for loops may not work.
#
# Note 4: I always run as root.
#
# Note 5: some parts are too old and don't work anymore. Some
# never worked.
#
# Note 6: the definitions for the find-xxxfile commands are on my
# .emacs.
#
# Note 7: if you see a strange command check my .zshrc -- it may
# be defined there as a function or an alias.
#
# Note 8: the sections without dates are always older than the
# sections with dates.

In normal operation, OPAM only alters files within ~/.opam.

During this initialisation, you can allow OPAM to add information to two
other files for best results. You can also make these additions manually
if you wish.

If you agree, OPAM will modify:

  - ~/.zshrc (or a file you specify) to set the right environment
    variables and to load the auto-completion scripts for your shell (zsh)
    on startup. Specifically, it checks for and appends the following line:

    . /home/edrx/.opam/opam-init/init.zsh > /dev/null 2> /dev/null || true


  - ~/.ocamlinit to ensure that non-system installations of `ocamlfind`
    (i.e. those installed by OPAM) will work correctly when running the
    OCaml toplevel. It does this by adding $OCAML_TOPLEVEL_PATH to the list
    of include directories.

If you choose to not configure your system now, you can either configure
OPAM manually (instructions will be displayed) or launch the automatic setup
later by running:

   opam config setup -a


Do you want OPAM to modify ~/.zshrc and ~/.ocamlinit?
(default is 'no', use 'f' to name a file other than ~/.zshrc)
    [N/y/f] 

Global configuration:
  Updating ~/.opam/opam-init/init.sh
  Updating ~/.opam/opam-init/init.zsh
  Updating ~/.opam/opam-init/init.csh
  Updating ~/.opam/opam-init/init.fish

1. To configure OPAM in the current shell session, you need to run:

      eval `opam config env`

2. To correctly configure OPAM for subsequent use, add the following
   line to your profile file (for instance ~/.zshrc):

      . /home/edrx/.opam/opam-init/init.zsh > /dev/null 2> /dev/null || true

3. To avoid issues related to non-system installations of `ocamlfind`
   add the following lines to ~/.ocamlinit (create it if necessary):

      let () =
        try Topdirs.dir_directory (Sys.getenv "OCAML_TOPLEVEL_PATH")
        with Not_found -> ()
      ;;

<edrx> hi all - I'm a beginner who has only followed some basic tutorials, but
       I haven't even used any libraries/modules yet...
<edrx> I'm wondering if it's easy to make ocaml call an external program -
       say, for an example/prototype, tac
<edrx> ...with a given input, and capture what it spits on stdout, and returns
       that as a string...
<edrx> where can I learn how do to that? any recommended links?
<edrx> actually the external program that I want to call is this one:

   Quick setup for EMACS
   -------------------
   Add opam emacs directory to your load-path by appending this to your .emacs:
     (let ((opam-share (ignore-errors (car (process-lines "opam" "config" "var" "share")))))
      (when (and opam-share (file-directory-p opam-share))
       ;; Register Merlin
       (add-to-list 'load-path (expand-file-name "emacs/site-lisp" opam-share))
       (autoload 'merlin-mode "merlin" nil t nil)
       ;; Automatically start it in OCaml buffers
       (add-hook 'tuareg-mode-hook 'merlin-mode t)
       (add-hook 'caml-mode-hook 'merlin-mode t)
       ;; Use opam switch to lookup ocamlmerlin binary
       (setq merlin-command 'opam)))
