;;; 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 followng #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
|
|
;;
|

|
|
;;
|
|
;; 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 indention #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

|
|
;; explicitly specified interface. Probably need to do this
|
|
;; for methods, too.

;; - fontify the optional alias before namespace in a using (import).
|
|
;; - Tweak open-curly magic insertion for object initializers.
|
|

A vsemi is a cc-mode concept implying the end of a statement,
|
|
where no actual end-of-statement signifier character ( semicolon,
|
|
close-brace) appears. The concept is used to allow proper
|
|
indenting of blocks of code: Where a vsemi appears, the following
|
|
line will not indent further.
|
|
|
|
A vsemi appears in 2 cases in C#:
|
|
|
|
- after an attribute that decorates a class, method, field, or
|
|
property.
|
|
|
|
- in an object initializer, before the open-curly?
|
|
|
|
An example of the former is [WebMethod] or [XmlElement].
|
|
|
|
Providing this function allows the indenting in `csharp-mode'
|
|
to work properly with code that includes attributes."

|

|
|
;;
|
|
;; 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)
|

This fn gets bound to / (the slash key), in

|
|
third consecutive slash, then a xml code documentation template
|

may be inserted in some cases. For example,
|
|
|

a <summary> template is inserted if the prior line is empty,

a <remarks> template is inserted if the prior word

a <returns> template is inserted if the prior word

closes the <remarks> element;

an <example> template is inserted if the prior word closes

|
the <returns> element;

a <para> template is inserted if the prior word closes

(define-derived-mode csharp-mode prog-mode "C#"
|
|
"Major mode for editing C# code.
|
|
|
|
The mode provides fontification and indent for C# syntax, as well
|
|
as some other handy features.
|
|
|
|
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:
|
|
|
|
(defun my-csharp-mode-fn ()
|
|
\"my function that runs when csharp-mode is initialized for a buffer.\"
|
|
(turn-on-font-lock)
|
|
(turn-on-auto-revert-mode) ;; helpful when also using Visual Studio
|
|
(setq indent-tabs-mode nil) ;; tabs are evil
|
|
....your own code here...
|
|
)
|
|
(add-hook 'csharp-mode-hook 'my-csharp-mode-fn t)
|
|
|
|
|
|
The function above is just a suggestion.
|
|
|
|
|
|
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'.
