|
|
|
|
* 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:
|
|
|
|
$ darcs get http://darcs.ocamlcore.org/repos/utop
