A universal toplevel for OCaml.
url: https://forge.ocamlcore.org/projects/utop/
* Requirements:
utop depends on the lambda-term package, which is available at:
https://forge.ocamlcore.org/projects/lambda-term/
* Installation:
To compile and install lambda-term just type:
$ ocaml setup.ml -configure
$ ocaml setup.ml -build
$ ocaml setup.ml -install
If you get the development version of utop you must obtain oasis
(http://oasis.forge.ocamlcore.org/).
* Usage:
To use utop, simply run:
$ utop
utop display a bar after the prompt which is used to show possible
completions in real-time. You can navigate in it using Alt+Left and
Alt+Right, and select one completion using Alt+Tab.
* Customization:
To add colors to utop, copy one of the files utoprc-dark or
utoprc-light to ~/.utoprc. utoprc-dark is for terminals with dark
colors (such as white on black) and utoprc-light is for terminals
with light colors (such as black on white).
You can also customize the prompt of utop by setting the reference
UTop.prompt.
* Integration with emacs:
To use utop in emacs, add the following line to your ~/.emacs file:
(autoload 'utop "utop" "Toplevel for OCaml" t)
Then you can run utop by executing the command "utop" in emacs.
* Integration with the tuareg mode:
You can replace the default toplevel used by the tuareg mode by
utop, for that add the following lines to your ~/.emacs file:
(autoload 'utop-eval-region "utop" "Toplevel for OCaml" t)
(autoload 'utop-eval-phrase "utop" "Toplevel for OCaml" t)
(autoload 'utop-eval-buffer "utop" "Toplevel for OCaml" t)
(defun tuareg-utop-hook ()
(local-set-key "\M-\C-x" 'utop-eval-phrase)
(local-set-key "\C-x\C-e" 'utop-eval-phrase)
(local-set-key "\C-c\C-e" 'utop-eval-phrase)
(local-set-key "\C-c\C-r" 'utop-eval-region)
(local-set-key "\C-c\C-b" 'utop-eval-buffer))
(add-hook 'tuareg-mode-hook 'tuareg-utop-hook)
* Development:
The last development version of utop can always be found in the
darcs repository hosted at darcs.ocamlcore.org:
