Enable (or disable) subword mode. In subword mode, Emacs's word commands recognize upper case letters in ‘StudlyCapsIdentifiers’ as word boundaries. This is indicated by the flag ‘/w’ on the mode line after the mode name (e.g. ‘C/law’). You can even use M-x c-subword-mode in non-CC Mode buffers.
In the GNU project, we recommend using underscores to separate words within an identifier in C or C++, rather than using case distinctions.
This command inserts a line break and indents the new line in a manner
appropriate to the context. In normal code, it does the work of C-j
(newline-and-indent), in a C preprocessor line it additionally
inserts a ‘\’ at the line break, and within comments it's like
M-j (c-indent-new-comment-line).
c-context-line-break isn't bound to a key by default, but it needs a
binding to be useful. The following code will bind it to C-j. We use
c-initialization-hook here to make sure the keymap is loaded before
we try to change it.
(defun my-bind-clb () (define-key c-mode-base-map "\C-j" 'c-context-line-break)) (add-hook 'c-initialization-hook 'my-bind-clb) |
Put mark at the end of a function definition, and put point at the beginning
(c-mark-function).
Fill a paragraph, handling C and C++ comments (c-fill-paragraph). If
any part of the current line is a comment or within a comment, this command
fills the comment or the paragraph of it that point is in, preserving the
comment indentation and comment delimiters.
Run the C preprocessor on the text in the region, and show the result, which
includes the expansion of all the macro calls (c-macro-expand). The
buffer text before the region is also included in preprocessing, for the
sake of macros defined there, but the output from this part isn't shown.
When you are debugging C code that uses macros, sometimes it is hard to figure out precisely how the macros expand. With this command, you don't have to figure it out; you can see the expansions.
Insert or align ‘\’ characters at the ends of the lines of the region
(c-backslash-region). This is useful after writing or editing a C
macro definition.
If a line already ends in ‘\’, this command adjusts the amount of whitespace before it. Otherwise, it inserts a new ‘\’. However, the last line in the region is treated specially; no ‘\’ is inserted on that line, and any ‘\’ there is deleted.
Highlight parts of the text according to its preprocessor conditionals. This command displays another buffer named ‘*CPP Edit*’, which serves as a graphic menu for selecting how to display particular kinds of conditionals and their contents. After changing various settings, click on ‘[A]pply these settings’ (or go to that buffer and type a) to rehighlight the C mode buffer accordingly.
Display the syntactic information about the current source line
(c-show-syntactic-information). This information directs how the
line is indented.
CWarn minor mode highlights certain suspicious C and C++ constructions:
You can enable the mode for one buffer with the command M-x
cwarn-mode, or for all suitable buffers with the command M-x
global-cwarn-mode or by customizing the variable global-cwarn-mode.
You must also enable Font Lock mode to make it work.
Hide-ifdef minor mode hides selected code within ‘#if’ and
‘#ifdef’ preprocessor blocks. See the documentation string of
hide-ifdef-mode for more information.
Find a file “related” in a special way to the file visited by the current
buffer. Typically this will be the header file corresponding to a C/C++
source file, or vice versa. The variable ff-related-file-alist
specifies how to compute related file names.
