.SH DESCRIPTION
|
|
|
|
.B utop
|
|
is a enhanced toplevel for OCaml with many features, including context
|
|
sensitive completion.
|
|
|
|
When you start
|
|
.B utop
|
|
what you see is the prompt followed by a bar containing words. This is
|
|
the completion bar, it contains the possible completion and is updated
|
|
as you type. The highlighted word in the completion bar is the
|
|
selected word. You can navigate using the keys Alt+Left and Alt+Right
|
|
and you can complete using the currently selected word by pressing
|
|
Alt+Tab (you can configure these bindings in the file
|
|
.I ~/.lambda-term-inputrc
|
|
, see
|
|
.BR lambda-term-inputrc (5)
|
|
for details).
|
|
|
|
utop supports completion on:
|
|
|
|
* directives and directive arguments
|
|
* identifiers
|
|
* record fields
|
|
* variants
|
|
* function labels
|
|
* object methods
|
|
|
|
Colors are by default configured for terminals with dark colors, such
|
|
as white on black, so the prompt may looks too bright on light colors
|
|
terminals. You can change that by setting the color profile of
|
|
utop. For that type:
|
|
|
|
UTop.set_profile UTop.Light;;
|
|
|
|
You can then add this line to your
|
|
.I ~/.ocamlinit
|
|
file.
|
|
|
|
You can enable basic syntax highlighting in utop by writing a
|
|
.I ~/.utoprc
|
|
file. See
|
|
.BR utoprc (5)
|
|
for that.
|
|
|
|
Finally utop can run in emacs. For that you have to add the following line to your
|
|
.I ~/.emacs
|
|
file:
|
|
|
|
(autoload 'utop "utop" "Toplevel for OCaml" t)
|
|
|
|
then you can run utop by pressing M-x and typing "utop". utop support
|
|
completion in emacs mode. Just press Tab to complete a word. You can
|
|
also integrate it with the tuareg mode. For that add the following
|
|
lines to your
|
|
.I ~/.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)
