Moreover, support for hilite and font +lock was added. + +This package is based on the original caml-mode for caml-light by +Xavier Leroy, extended with indentation by Ian Zimmerman. For details +see README.itz, which is the README from Ian Zimmerman's package. + +To use it, just put the .el files in your path, and add the following +three lines in your .emacs. + + (setq auto-mode-alist + (cons '("\\.ml[iylp]?$" . caml-mode) auto-mode-alist)) + (autoload 'caml-mode "caml" "Major mode for editing Caml code." t) + (autoload 'run-caml "inf-caml" "Run an inferior Caml process." t) + +I added camldebug.el from the original distribution, since there will +soon be a debugger for Objective Caml, but I do not know enough about +it. + +To use highlighting capabilities, add ONE of the following two +lines to your .emacs. + + (if window-system (require 'caml-hilit)) + (if window-system (require 'caml-font)) + +caml.el and inf-caml.el can be used collectively, but it might be a +good idea to copy caml-hilit.el or caml-font.el to you own directory, +and edit it to your taste and colors. + +Main key bindings: + +TAB indent current line +C-c C-q indent phrase +C-c C-a switch between interface and implementation +C-c C-c compile (usually make) +C-x` goto next error (also mouse button 2 in the compilation log) + +Once you have started caml by M-x run-caml: + +M-C-x send phrase to inferior caml process (also C-c C-e) +C-c C-r send region to inferior caml process + +For other bindings, see C-h b. + +Changes from the original packages are: + +* support of Objective Caml and Objective Label. + +* an indentation very close to mine, which happens to be the same as + Xavier's, since the sources of the Objective Caml compiler do not + change if you indent them in this mode. + +* highlighting. + +Changes from previous versions: + +* many bugs corrected. + +* (partial) compatibility with Caml-Light added. + (setq caml-quote-char "`") + (setq inferior-caml-program "camllight") + Literals will be correctly understood and highlighted. However, + indentation rules are still Objective Caml's: this just happens to + work well in most cases, but is only intended for occasional use. + +* as many people asked for it, application is now indented. This seems + to work well: this time differences in indentation between the + compiler's source and this mode are really exceptionnal. On the + other hand, you may think that some special cases are strange. No + miracle. + +* nicer behaviour when sending a phrase/region to the inferior caml + process. + +Some remarks about the style supported: + +Since Objective Caml's syntax is very liberal (more than 100 +shift-reduce conflicts with yacc), automatic indentation is far from +easy. Moreover, you expect the indentation to be not purely syntactic, +but also semantic: reflecting the meaning of your program. + +This mode tries to be intelligent. For instance some operators are +indented differently in the middle and at the end of a line (thanks to +Ian Zimmerman). Also, we do not indent after if .. then .. else, when +else is on the same line, to reflect that this idiom is equivalent to +a return instruction in a more imperative language, or after the in of +let .. in, since you may see that as an assignment. + +However, you may want to use a different indentation style. This is +made partly possible by a number of variables at the beginning of +caml.el. Try to set them. However this only changes the size of +indentations, not really the look of your program. This is enough to +disable the two idioms above, but to do anything more you will have to +edit the code... Enjoy! + +This mode does not force you to put ;; in your program. This means +that we had to use a heuristic to decide where a phrase stops, to +speed up the code. A phrase ends when any of the keywords let, type, +class, module, exception, val, external, appears at the beginning of a +line. Using the first column in other cases may confuse it. + +Last remark: this mode is O'Labl compatible. This is a very small +change, but ":" is registered as part of words (to make labels). As a +result, you should not write a keyword next to it (without space). You +can disable this by editing caml.el and inf-caml.el. + +Comments and bug reports to + + Jacques Garrigue <garrigue@kurims.kyoto-u.ac.jp> |
