url: https://forge.ocamlcore.org/projects/utop/
|
|
|
|
* Requirements:
|
|
|
|
utop depends on the following packages:
|
|
|
|
* findlib (http://projects.camlcity.org/projects/findlib.html)
|
|
* react (http://erratique.ch/software/react)
|
|
* lwt (http://ocsigen.org/lwt/)
|
|
* camomile (http://camomile.sourceforge.net/)
|
|
* zed (http://forge.ocamlcore.org/projects/zed/)
|
|
* lambda-term (http://forge.ocamlcore.org/projects/lambda-term/)
|
|
|
|
Lwt must be compiled with react support, configure it with:
|
|
|
|
$ ./configure --enable-react
|
|
|
|
utop also requires OCaml compiler libraries. If you are using
|
|
debian, they are available as the package ocaml-compiler-libs, if
|
|
you are using godi, they are installed by default. If you installed
|
|
ocaml by hand, you can run the script utils/install-compiler-libs.sh.
|
|
|
|
* 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/typerex mode:
|
|
|
|
You can replace the default toplevel used by the tuareg or typerex
|
|
mode by utop, for that add the following lines to your ~/.emacs
|
|
file:
|
|
|
|
(autoload 'utop-setup-ocaml-buffer "utop" "Toplevel for OCaml" t)
|
|
(add-hook 'tuareg-mode-hook 'utop-setup-ocaml-buffer)
|
|
(add-hook 'typerex-mode-hook 'utop-setup-ocaml-buffer)
|
|
|
|
You can also complete text in a tuareg or typerex buffer using the
|
|
environment of the toplevel. For that bind the function
|
|
"utop-edit-complete" to the key you want.
|
|
|
|
* 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
