[Caml-list] How to use emacs tuareg mode effectively to manage an OCaml project?

Hi all

I am using OCaml for a project with 20 - 50 files inside. Also I am using emacs
+ tuareg.

Syntax highlight is well done by tuareg and generally it is good using
emacs for one file editing.

However, for the project files, I need to frequently switch between files
together with folders, how can i use emacs as also a project manager such
as eclipse? How can I have a file / project tree there just like Eclipse
does?

Also how do people manage a huge bunch of files (just like core library or
batteries-included) effectively? It seems emacs is good for single file or
simple project editing, but not good at managing a complex project.

thanks
Best Regards,

Xinuo

Hi Xinuo,

I use projectile (https://github.com/bbatsov/projectile) to navigate large
projects. It isn't OCaml specific but it works really well IMO.

This post contains lots of good tips when using Emacs for OCaml
programming: http://chaudhuri.info/misc/osetup/

You definitely also want to checkout UTop and get comfortable using it from
Emacs: https://github.com/diml/utop

Best of luck,
Mads

You could give the dirtree mode a try.

http://melpa.milkbox.net/#/dirtree
http://www.emacswiki.org/emacs/dirtree.el
http://stackoverflow.com/questions/9546562/emacs-dirtree-directory-tree-view-setup

M-x dirtree and accept current directory or enter another directory
and you are present with a left-hand pane containing a directory tree
that you can navigate and press enter to select a file for
viewing/editing.

I've always enjoyed the tab completion emacs provides when searching for
files. It feels like a working tree generated on demand. Also, I've found
that buffers scale much nicer to many files than tabs. Free yourself from
the GUI!

Indeed:

  $ cd libguestfs
  $ find -name '*.ml' -o -name '*.mli' | wc -l
  206

I guess we're doing OK using just emacs (except for 1 person using
that "visual" editor that shall not be named).

I'm interested in the particular problems that the OP has with
navigating through a small collection of files.

Hi,

I daily use emacs with dozens of buffers.
I use the Iswitchb emacs mode. This mode is included into emacs but may 
be not on by default.
To enable it add

  '(iswitchb-mode t nil (iswitchb))

to your custom-set-variables in your .emacs file
or use the customization group gui : convenience > Iswitchb.

CTRL-x b displays the list of buffers in the mini-buffer (sorted by the 
last access time).
CTRL-s to select next buffer
CTRL-r to select previous buffer
Type a string to reduce the buffer list, typically 2 or 3 char are 
sufficient.

I find it much fast to navigate than tabs or menus.

Regards,

Denis Berthod

Slightly different from what you ask for, but there are several ways to
jump-to-definition and find-uses for identifiers, which helps get around
large project a lot.

Others may point to different options, but ocp-index [1] is very efficient for that (`C-c ;` to jump to definition, `C-c /` to find uses) ; you just need to enable -bin-annot in your build system and it should work out-of-the box.

I read Linus Torvalds writing emacs is his preferred editor.
I also read that he is working on a pretty complex project. ;)
