;;; Commentary:
|
|
;;
|
|
;; This is a separate mode to implement the C# constructs and
|
|
;; font-locking. It is based on the java-mode example from cc-mode.
|
|
;;
|
|
;; 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.
|
|
;;
|
|
;; - intelligent inserttion of matched pairs of curly braces.
|
|
;;
|
|
;; - sets the compiler regex for next-error, for csc.exe output.
|
|
;;
|
|
;;
|
|
|
|
|
|
;;; To use:
|
|
;;
|
|
;; put this in your .emacs:
|
|
;;
|
|
;; (autoload 'csharp-mode "csharp-mode" "Major mode for editing C# code." t)
|
|
;;
|
|
;; or:
|
|
;;
|
|
;; (require 'csharp-mode)
|
|
;;
|
|
;;
|
|
;; AND:
|
|
;;
|
|
;; (setq auto-mode-alist
|
|
;; (append '(("\\.cs$" . csharp-mode)) auto-mode-alist))
|
|
;; (defun my-csharp-mode-fn ()
|
|
;; "function that runs when csharp-mode is initialized for a buffer."
|
|
;; ...insert your code here...
|
|
;; ...most commonly, your custom key bindings ...
|
|
;; )
|
|
;; (add-hook 'csharp-mode-hook 'my-csharp-mode-fn t)
|
|
;;
|
|
;;
|
|
|
|
|
|
;;; Bugs:
|
|
;;
|
|
;; Namespaces in the using statements are not fontified. Should do in
|
|
;; c-basic-matchers-before or c-basic-matchers-after.
|
|
;;
|
|
;; Method names with a preceding attribute are not fontified.
|
|
;;
|
|
;; Field/Prop names inside object initializers are fontified only
|
|
;; if the null constructor is used, with no parens.
|
|
;;
|
|
;; 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:
|
|
;;
|
|
;; Get csharp-mode.el accepted as part of the emacs standard distribution.
|
|
;; Must contact monnier at iro.umontreal.ca to make this happen.

|
;;; 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 linefeed.
|
|
;; - intelligent curly-brace insertion
|
|
;; 0.7.4 - added a C# style
|
|
;; - using is now a keyword and gets fontified
|
|
;; - fixed a bug that had crept into the codedoc insertion

(local-set-key (kbd \"{\") 'csharp-insert-open-brace)
|
|
|
|
The default binding for an open curly brace in cc-modes is often
|
|
`c-electric-brace' or `skeleton-pair-insert-maybe'. The former
|
|
can be configured to insert newlines around braces in various
|
|
syntactic positions. The latter inserts a pair of braces and
|
|
then does not insert a newline, and does not indent.
|
|
|
|
This fn provides another option, with some additional
|
|
intelligence for csharp-mode. When you type an open curly, the
|
|
appropriate pair of braces appears, with spacing and indent set
|
|
in a context-sensitive manner.
|
|
|
|
Within a string literal, you just get a pair of braces, and point
|
|
is set between them. Following an equals sign, you get a pair of
|
|
braces, with a semincolon appended. Otherwise, you
|
|
get the open brace on a new line, with the closing brace on the
|
|
line following.
|
|
|

There may be another way to get this to happen appropriately just within emacs,
|
|
but I could not figure out how to do it. So I wrote this alternative.

;; Commentary:
|
|
;;
|
|
;; The purpose of the following code is to fix font-lock for C#,
|
|
;; specifically for the verbatim-literal strings. C# is a cc-mode
|
|
;; language and strings are handled mostly like other c-based
|
|
;; languages. The one exception is the verbatim-literal string, which
|
|
;; uses the syntax @"...".
|
|
;;
|
|
;; `parse-partial-sexp' treats those strings as just regular strings,
|
|
;; with the @ a non-string character. This is fine, except when the
|
|
;; verblit string ends in a slash, in which case, font-lock breaks from
|
|
;; that point onward in the buffer.
|
|
;;
|
|
;; This is an attempt to fix that.
|
|
;;
|
|
;; The idea is to scan the buffer in full for verblit strings, and apply the
|
|
;; appropriate syntax-table text properties for verblit strings. Also setting
|
|
;; `parse-sexp-lookup-properties' to t tells `parse-partial-sexp'
|
|
;; to use the syntax-table text properties set up by the scan as it does
|
|
;; its parse.
|
|
;;
|
|
;; Also need to re-scan after any changes in the buffer, but on a more
|
|
;; limited region.
|
|
;;
|
|
|

;; ;; I don't remember what this is supposed to do,
|

;; ;; or how I figured out the value.
