commit 134eeb6aa323beff3e93d056e5766ea50916157e
Author: Theodor Thornhill <theo@thornhill.no>
Commit: Theodor Thornhill <theo@thornhill.no>
Complete rework
Started from scratch, following only CC Mode api and directives. There is
one
monkey pach still haunting us, but hopefully we can remove it soon(tm).

-;;; Commentary:
-;;
-;; This is a major mode for editing C# code. It performs automatic
-;; indentation of C# syntax; font locking; and integration with
-;; imenu.el.
-;;
-;; csharp-mode requires CC Mode 5.30 or later. It works with
-;; cc-mode 5.31.3, which is current at this time.
-;;
-;; Features:
-;;
-;; - font-lock and indent of C# syntax including:
-;; all c# keywords and major syntax
-;; attributes that decorate methods, classes, fields, properties
-;; enum types
-;; #if/#endif #region/#endregion
-;; instance initializers
-;; anonymous functions and methods
-;; verbatim literal strings (those that begin with @)
-;; generics
-;;
-;; - automagic code-doc generation when you type three slashes.
-;;
-;; - compatible with electric-pair-mode for intelligent insertion
-;; of matched braces, quotes, etc.
-;;
-;; - imenu integration - generates an index of namespaces, classes,
-;; interfaces, methods, and properties for easy navigation within
-;; the buffer.
-;;
-
-
-;; Installation instructions
-;; --------------------------------
-;;
-;; Put csharp-mode.el somewhere in your load path, optionally byte-compile
-;; it, and add the following to your .emacs file:
-;;
-;; (autoload 'csharp-mode "csharp-mode" "Major mode for editing C# code." t)
-;; (setq auto-mode-alist
-;; (append '(("\\.cs$" . csharp-mode)) auto-mode-alist))
-;;
-;;
-;; Optionally, define and register a mode-hook function. To do so, use
-;; something like this in your .emacs file:
-;;
-;; (defun my-csharp-mode-fn ()
-;; "function that runs when csharp-mode is initialized for a buffer."
-;; (turn-on-auto-revert-mode)
-;; (setq indent-tabs-mode nil)
-;; ...insert more code here...
-;; ...including any custom key bindings you might want ...
-;; )
-;; (add-hook 'csharp-mode-hook 'my-csharp-mode-fn t)
-;;
-;;
-;; General
-;; ----------------------------
-;;
-;; Mostly C# mode will "just work." Use `describe-mode' to see the
-;; default keybindings and the highlights of the mode.
-;;
-;;
-;; imenu integration
-;; -----------------------------
-;;
-;; This should just work. For those who don't know what imenu is, it
-;; allows navigation to different points within the file from an
-;; "Index" menu, in the window's menubar. csharp-mode computes the
-;; menu containing the namespaces, classes, methods, and so on, in the
-;; buffer. This happens at the time the file is loaded; for large
-;; files it takes a bit of time to complete the scan. If you don't
-;; want this capability, set `csharp-want-imenu' to nil.
-;;
-;;
-
-
-;;; Known Bugs:
-;;
-;; The imenu scan is text-based and naive. For example, if you
-;; intersperse comments between the name of a class/method/namespace,
-;; and the curly brace, the scan will not recognize the thing being
-;; declared. This is fixable - would need to extract the buffer
-;; substring then remove comments before doing the regexp checks - but
-;; it would make the scan much slower. Also, the scan doesn't deal
-;; with preproc symbol definitions and #if/#else. Those things are
-;; invisible to the scanner csharp-mode uses to build the imenu menu.
-;;
-;; Leading identifiers are no longer being fontified, for some reason.
-;; See matchers-before. (Not sure this is still a problem - 19 may
-;; 2011 DPC)
-;;
-;; Method names with a preceding attribute are not fontified.
-;;
-;; The symbol following #if is not fontified. It should be treated like
-;; define and get font-lock-variable-name-face .
-;;
-;; This code doesn't seem to work when you compile it, then
-;; load/require in the emacs file. You will get an error (error
-;; "`c-lang-defconst' must be used in a file") which happens because
-;; cc-mode doesn't think it is in a buffer while loading directly
-;; from the init. However, if you call it based on a file extension,
-;; it works properly. Interestingly enough, this doesn't happen if
-;; you don't byte-compile cc-mode.
-;;
-;;
-;;
-;; Todo:
-;;
-;; imenu should scan for and find delegates and events, in addition
-;; to the classes, structs, properties and methods it does currently.
-;;
-;; Get csharp-mode.el accepted as part of the emacs standard distribution.
-;; Must contact monnier at iro.umontreal.ca to make this happen.
-;;
-;; Add refactoring capabilities?
-;; - extract as method - extract a block of code into a method
-;; - extract as Func<> - extract a block of code into an Action<T>
-;;
-;; More code-gen power:
-;; - interface implementation - I think would require csharp-shell
-;;
-;;
-;; Acknowledgements:
-;;
-;; Thanks to Alan Mackenzie and Stefan Monnier for answering questions
-;; and making suggestions. And to Trey Jackson for sharing his
-;; knowledge of emacs lisp.
-;;
-;;
-
-;;; Versions:
-;;
-;; 0.1.0 - Initial release.
-;; 0.2.0 - Fixed the identification on the "enum" keyword.
-;; - Fixed the font-lock on the "base" keyword
-;; 0.3.0 - Added a regex to fontify attributes. It isn't the
-;; the best method, but it handles single-like attributes
-;; well.
-;; - Got "super" not to fontify as a keyword.
-;; - Got extending classes and interfaces to fontify as something.
-;; 0.4.0 - Removed the attribute matching because it broke more than
-;; it fixed.
-;; - Corrected a bug with namespace not being properly identified
-;; and treating the class level as an inner object, which screwed
-;; up formatting.
-;; - Added "partial" to the keywords.
-;; 0.5.0 - Found bugs with compiled cc-mode and loading from init files.
-;; - Updated the eval-when-compile to code to let the mode be
-;; compiled.
-;; 0.6.0 - Added the c-filter-ops patch for 5.31.1 which made that
-;; function in cc-langs.el unavailable.
-;; - Added a csharp-lineup-region for indentation #region and
-;; #endregion block differently.
-;; 0.7.0 - Added autoload so update-directory-autoloads works
-;; (Thank you, Nikolaj Schumacher)
-;; - Fontified the entire #region and #endregion lines.
-;; - Initial work to get get, set, add, remove font-locked.
-;; 0.7.1 - Added option to indent #if/endif with code
-;; - Fixed c-opt-cpp-prefix defn (it must not include the BOL
-;; char (^).
-;; - proper fontification and indent of classes that inherit
-;; (previously the colon was confusing the parser)
-;; - reclassified namespace as a block beginner
-;; - removed $ as a legal symbol char - not legal in C#.
-;; - added struct to c-class-decl-kwds so indent is correct
-;; within a struct.
-;; 0.7.2 - Added automatic codedoc insertion.
-;; 0.7.3 - Instance initializers (new Type { ... } ) and
-;; (new Type() { ...} ) are now indented properly.
-;; - proper fontification and indent of enums as brace-list-*,
-;; including special treatment for enums that explicitly
-;; inherit from an int type. Previously the colon was
-;; confusing the parser.
-;; - proper fontification of verbatim literal strings,
-;; including those that end in slash. This edge case was not
-;; handled at all before; it is now handled correctly.
-;; - code cleanup and organization; removed the formfeed.
-;; - intelligent curly-brace insertion with
-;; `csharp-insert-open-brace'
-;; 0.7.4 - added a C# style
-;; - using is now a keyword and gets fontified correctly
-;; - fixed a bug that had crept into the codedoc insertion.
-;; 0.7.5 - now fontify namespaces in the using statements. This is
-;; done in the csharp value for c-basic-matchers-before .
-;; - also fontify the name following namespace decl.
-;; This is done in the csharp value for c-basic-matchers-after .
-;; - turn on recognition of generic types. They are now
-;; fontified correctly.
-;; - <> are now treated as syntactic parens and can be jumped
-;; over with c-forward-sexp.
-;; - Constructors are now fontified.
-;; - Field/Prop names inside object initializers are now fontified.
-;;
-;; 0.7.7 - relocate running c-run-mode-hooks to the end of
-;; csharp-mode, to allow user to modify key bindings in a
-;; hook if he doesn't like the defaults.
-;;
-;; 0.7.8 - redefine csharp-log to insert timestamp.
-;; - Fix byte-compile errors on emacs 23.2 ? Why was
-;; c-filter-ops duplicated here? What was the purpose of its
-;; presence here, I am not clear.
-;;
-;; 0.8.0 - include flymake magic into this module.
-;; - include yasnippet integration
-;;
-;; 0.8.2 2011 April DPC
-;; - small tweaks; now set a one-time bool for flymake installation
-;; - some doc updates on flymake
-;;
-;; 0.8.3 2011 May 17 DPC
-;; - better help on csharp-mode
-;; - csharp-move-* functions for manual navigation.
-;; - imenu integration for menu-driven navigation - navigate to
-;; named methods, classes, etc.
-;; - adjusted the flymake regexp to handle output from fxcopcmd,
-;; and extended the help to provide examples how to use this.
-;;
-;; 0.8.4 DPC 2011 May 18
-;; - fix a basic bug in the `csharp-yasnippet-fixup' fn.
-;;
-;; 0.8.5 DPC 2011 May 21
-;; - imenu: correctly parse Properties that are part of an
-;; explicitly specified interface. Probably need to do this
-;; for methods, too.

-;; description. (Why on font-lock-keywords? I don't know, but that's
-;; where you get the help.)
-;;
-;; Aside from the provided documentation, the other option of course, is
-;; to look in the source code as an example for what to do. The source
-;; in cc-fonts uses a defun c-make-font-lock-search-function to produce
-;; most of the matchers. Called this way:
-;;
-;; (c-make-font-lock-search-function regexp '(A B c))
-;;
-;; The REGEXP is used in re-search-forward, and if there's a match, then
-;; A is called within a save-match-data. If B and C are non-nil, they
-;; are called as pre and post blocks, respecitvely.
-;;
-;; Anyway the c-make-font-lock-search-function works for a single regex,
-;; but more complicated scenarios such as those intended to match and
-;; fontify object initializers, call for a hand-crafted lambda.
-;;
-;; The object initializer is special because matching on it must
-;; allow nesting.
-;;
-;; In c#, the object initializer block is used directly after a
-;; constructor, like this:
-;;
-;; new MyType
-;; {
-;; Prop1 = "foo"
-;; }
-;;
-;; csharp-mode needs to fontify the properties in the
-;; initializer block in font-lock-variable-name-face. The key thing is
-;; to set the text property on the open curly, using type c-type and
-;; value c-decl-id-start. This apparently allows `parse-partial-sexp' to
-;; do the right thing, later.
-;;
-;; This simple case is easy to handle in a regex, using the basic
-;; `c-make-font-lock-search-function' form. But the general syntax for a
-;; constructor + object initializer in C# is more complex:
-;;
-;; new MyType(..arglist..) {
-;; Prop1 = "foo"
-;; }
-;;
-;; A simple regex match won't satisfy here, because the ..arglist.. can
-;; be anything, including calls to other constructors, potentially with
-;; object initializer blocks. This may nest arbitrarily deeply, and the
-;; regex in emacs doesn't support balanced matching. Therefore there's
-;; no way to match on the "outside" pair of parens, to find the relevant
-;; open curly. What's necessary is to do the match on "new MyType" then
-;; skip over the sexp defined by the parens, then set the text property on
-;; the appropriate open-curly.
-;;
-;; To make that happen, it's good to have insight into what the matcher
-;; really does. The output of `c-make-font-lock-search-function' before
-;; byte-compiling, is:
-;;
-;; (lambda (limit)
-;; (let ((parse-sexp-lookup-properties
-;; (cc-eval-when-compile
-;; (boundp 'parse-sexp-lookup-properties))))
-;; (while (re-search-forward REGEX limit t)

-;; (goto-char (match-end 0))
-;; (progn
-;; B
-;; (save-match-data A)
-;; C ))))
-;; nil)
-;;
-;; csharp-mode uses this hand-crafted form of a matcher to handle the
-;; general case for constructor + object initializer, within
-;; `c-basic-matchers-after' .

-The mode provides fontification and indent for C# syntax, as well

-
-At mode startup, there are two interesting hooks that run:
-`prog-mode-hook' is run with no args, then `csharp-mode-hook' is run after
-that, also with no args.
-
-To run your own logic after csharp-mode starts, do this:
-

- (turn-on-font-lock)

-
-Imenu Integration
-===============================
-
-Check the menubar for menu entries for Imenu; it is labelled
-\"Index\".
-
-The Imenu index gets computed when the file is .cs first opened and loaded.
-This may take a moment or two. If you don't like this delay and don't
-use Imenu, you can turn this off with the variable `csharp-want-imenu'.
