C/C++ Support *c-support* *csupport*
Plugin version 5.0.5
for Vim version 6.0 and above
Fritz Mehner <mehner@fh-swf.de>
C/C++-IDE for Vim/gVim. It is written to considerably speed up writing code in
a consistent style. This is done by inserting complete statements,idioms, code
snippets, templates, and comments. Syntax checking, compiling, running a
program, running a code checker or indent can be done with a keystroke.

How to add this help file to Vim's help |add-local-help|
==============================================================================
1. USAGE WITH GUI (gVim) *csupport-usage-gvim*
==============================================================================
If the root menu 'C/C++' is not visible call it with the item "Load C Support"
from the standard Tools-menu.
The item "Load C Support" can also be used to unload the C/C++-root menu.
Nearly all menu entries insert code snippets or comments. All these stuff is
taken from template files and can be changed by the user to meet his
requirements (see|csupport-templates|).
------------------------------------------------------------------------------
1.1 MENU 'Comments' *csupport-comm*
------------------------------------------------------------------------------
1.1.1 APPEND ALIGNED COMMENTS TO CONSECUTIVE LINES *csupport-comm-aligned*
In NORMAL MODE the menu items 'end-of-line comment' will append an comment to
the current line.
In VISUAL MODE these item will append aligned comments to all marked lines.
Marking the first 4 lines
print_double_array ( double array[],
int n,
int columns,
char* arrayname
)
and choosing 'end-of-line com. /**/' will yield.
print_double_array ( double array[], /* */
int n, /* */
int columns, /* */
char* arrayname /* */
) /* */
If one ore more lines go beyond the starting column (s.below) the comments
will start at the 2. column after the longest line. The cursor will be
positioned inside the first comment.
The default starting column is 49 ( = (multiple of 2,4, or 8) + 1 ). This can
be changed by setting a global variable in the file ~/.vimrc , e.g. :
let g:C_LineEndCommColDefault = 45
The starting column can also be set by the menu item
'Comments->set end-of-line com. col' . Just position the cursor in an
arbitrary column (column number is shown in the Vim status line) and choose
this menu item. This setting is buffer related.
If the cursor was at the end of a line you will be asked for a column number
because this position is most likely not the desired starting column.
Your choice will be confirmed.
------------------------------------------------------------------------------
1.1.2 ADJUST END-OF-LINE COMMENTS *csupport-comm-realign*
After some changes end-of-line comments may be no longer aligned:
print_double_array ( double array[], /* */
long int n, /* */
unsigned int columns, /* */
char* a_name /* */
) /* */
Realignment can be achieved with the menu item 'adjust end-of-line com.' In
normal mode the comment (if any) in the current line will be aligned to the
end-of-line comment column (see above) if possible. In visual mode the
comments in the marked block will be aligned:
print_double_array ( double array[], /* */
long int n, /* */
unsigned int columns, /* */
char* a_name /* */
) /* */
------------------------------------------------------------------------------
1.1.3 CODE TO COMMENT *csupport-code-to-comm*
The marked block
xxxxxxxx
xxxxxxxx
xxxxxxxx
will be changed by the menu item 'code->comment /**/' into the multiline
comment (all (partially) marked lines):
/* xxxxxxxx
* xxxxxxxx
* xxxxxxxx
*/
The marked block will be changed by the menu item 'code->comment //' into the
multiline comment
//xxxxxxxx
//xxxxxxxx
//xxxxxxxx
The menu items works also for a single line. A single line needs not to be
marked.
------------------------------------------------------------------------------
1.1.4 COMMENT TO CODE *csupport-comm-to-code*
If one (or more) complete comment (i.e. all lines belonging to the comment) is
marked the item 'comment->code' will uncomment it. If the following lines
are marked
* printf ("\n");
*/
printf ("\n");
// printf ("\n");
//
/*
* printf ("\n");
*/
uncommenting will yield
* printf ("\n");
*/
printf ("\n");
printf ("\n");
printf ("\n");
The first 2 lines are only a part of a C-comment and remain unchanged.
A C-comment can start with /* , /** or /*! .
The menu item works also for a single line with a leading // . A single line
needs not to be marked.
------------------------------------------------------------------------------
1.1.5 FRAME COMMENTS, FILE HEADER, ... *csupport-comm-frame*
Frame comments, file header comments and function, methods, class descriptions
are read as templates from the appropriate files (see |csupport-templates|).
------------------------------------------------------------------------------
1.1.6 KEYWORD+comment *csupport-comm-keywords*
Preliminary comments to document (and find again) places where works will be
resumed shortly. Usually not meant for the final documentation.
------------------------------------------------------------------------------
1.1.7 C TO C++ COMMENTS AND VICE VERSA *csupport-comm-c-cpp*
The menu item '// xxx -> /* xxx */' changes a C++ comment into an C comment.
This is done for the current line in normal or insert mode and for a marked
area of lines in visual mode.
If there are multiple C comments only the first one will be changed:
printf ("\n"); /* one */ /* two */ /* three */
will be changed into
printf ("\n"); // one /* two */ /* three */
The menu item '/* xxx */ -> // xxx' changes a C comment into an C++ comment.
------------------------------------------------------------------------------
1.1.8 DATE AND DATE+TIME *csupport-comm-date*
The format for 'date' and 'date time' can be defined by the user (see
|csupport-templates-date|).
------------------------------------------------------------------------------
1.2 MENU 'Statements' *csupport-stat*
------------------------------------------------------------------------------
1.2.1 NORMAL MODE, INSERT MODE. *csupport-stat-normal-mode*
An empty statement will be inserted and properly indented. The item 'if{}'
will insert an if-statement:
if ( )
{
}
1.2.2 VISUAL MODE. *csupport-stat-visual-mode*
STATEMENTS WITH BLOCKS AND CASE LABEL.
--------------------------------------
The highlighted area
xxxxx
xxxxx
can be surrounded by one of the following statements:
+----------------------------+-----------------------------+
| if ( ) | if ( ) |
| { | { |
| xxxxx | xxxxx |
| xxxxx | xxxxx |
| } | } |
| | else |
| | { |
| | } |
+----------------------------+-----------------------------+
| for ( ; ; ) | while ( ) |
| { | { |
| xxxxx | xxxxx |
| xxxxx | xxxxx |
| } | } |
+----------------------------+-----------------------------+
| do | |
| { | { |
| xxxxx | xxxxx |
| xxxxx | xxxxx |
| } | } |
| while ( ); | |
+----------------------------+-----------------------------+
| switch ( ) { |
| case : |
| break; |
| |
| case : |
| break; |
| |
| case : |
| break; |
| |
| case : |
| break; |
| |
| default: |
| break; |
| } |
+----------------------------+-----------------------------+
For 'switch' and 'case' see |csupport-stat-switch| and |csupport-stat-case|.
The whole statement will be indented after insertion.
STATEMENTS WITHOUT BLOCKS.
--------------------------
One of the following statements can be inserted:
+-------------------------------+--------------------------+
| if ( ) | for ( ; ; ) |
+-------------------------------+--------------------------+
| if ( ) | while ( ) |
| else | |
+-------------------------------+--------------------------+
| case : | |
| break; | |
+-------------------------------+--------------------------+
------------------------------------------------------------------------------
1.3 MENU 'Preprocessor' *csupport-prep*
------------------------------------------------------------------------------
1.3.1 NORMAL MODE, INSERT MODE. *csupport-prep-normal-mode*
The preprocessor statements will be inserted and properly indented.
1.3.2 VISUAL MODE. *csupport-prep-visual-mode*
STATEMENTS WITH BLOCKS
----------------------
The highlighted area
xxxxx
xxxxx
can be surrounded by one of the following statements:
+----------------------------+-----------------------------+
| #if CONDITION |
| xxxxx |
| xxxxx |
| #else /* ----- #if CONDITION ----- */ |
| |
| #endif /* ----- #if CONDITION ----- */ |
+----------------------------------------------------------+
| #ifdef CONDITION |
| xxxxx |
| xxxxx |
| #else /* ----- #ifdef CONDITION ----- */ |
| |
| #endif /* ----- #ifdef CONDITION ----- */ |
+----------------------------------------------------------+
| #ifndef CONDITION |
| xxxxx |
| xxxxx |
| #else /* ----- #ifndef CONDITION ----- */ |
| |
| #endif /* ----- #ifndef CONDITION ----- */ |
+----------------------------------------------------------+
| #ifndef INC_TEST |
| #define INC_TEST |
| xxxxx |
| xxxxx |
| #endif /* ----- #ifndef INC_TEST ----- */ |
+----------------------------------------------------------+
| #if 0 /* ----- #if 0 : If0Label_1 ----- */ |
| |
| #endif /* ----- #if 0 : If0Label_1 ----- */ |
+----------------------------------------------------------+
The macro name for an include guard (e.g. INC_TEST above) will be derived as a
suggestion from the file name.
1.3.3 BLOCK OUT CODE WITH #if 0 ... #endif *csupport-prep-if0*
The menu item #if 0 #endif inserts the lines
#if 0 /* ----- #if 0 : If0Label_1 ----- */
#endif /* ----- #if 0 : If0Label_1 ----- */
In visual mode the marked block of lines will be surrounded by these lines.
This is usually done to temporarily block out some code. The label names like
If0Label_1 are automatically inserted into the comments. The trailing numbers
are automatically incremented. These numbers can be changed by the user. The
next number will be one above the highest number found in the current buffer.
A corresponding label can be found by searching with the vim star command (*).
All labels can be found with a global search like :g/If0Label_/ or
:g/If0Label_\d\+/. All corresponding lines can be deleted with :g/If0Label_/d .
REMOVE THE ENCLOSING #if 0 ... #endif -CONSTRUCT.
The menu item 'remove #if #endif' removes such a construct if the cursor is
in the middle of such a section or on one of the two enclosing lines. Nested
constructs will be untouched.
------------------------------------------------------------------------------
1.4 MENU 'Idioms' *csupport-idioms*
------------------------------------------------------------------------------
1.4.1 ENTRY 'function'
NORMAL MODE, INSERT MODE:
The name of the function is asked for and the following lines (for function
name "f") will be inserted:
void
f ( )
{
return ;
} /* ---------- end of function f ---------- */
VISUAL MODE:
Main or [static] function: the highlighted lines will go inside the new
function or main.
for-loops: the highlighted lines will be set in braces.
1.4.2 ENTRY 'open input file'
The item 'open input file' will create the statements to open and close an
input file (e.g. with the file pointer 'infile').
1.4.3 ENTRY 'open output file'
The item 'open output file' will create the statements to open and close an
output file (e.g. with the file pointer 'outfile').
------------------------------------------------------------------------------
1.5 MENU 'Snippets' *csupport-snippets*
------------------------------------------------------------------------------
1.5.1 CODE SNIPPETS
Code snippets are pieces of code which are kept in separate files in a special
directory (e.g. a few lines of code or a complete template for a Makefile).
File names are used to identify the snippets. The snippet directory will be
created during the installation ( $HOME/.vim/codesnippets-c is the default).
Snippets are managed with the 3 items
C/C++ -> Snippets -> read code snippet
C/C++ -> Snippets -> write code snippet
C/C++ -> Snippets -> edit code snippet
from the Snippets submenu.
CREATING A NEW SNIPPET
When nothing is marked, "write code snippet" will write the whole buffer
to a snippet file, otherwise the marked area will be written to a file.
INSERT A SNIPPET
Select the appropriate file from the snippet directory ("read code snippet").
The inserted lines will be indented.
EDIT A SNIPPET
This is a normal edit.
INDENTATION / NO INDENTATION
Code snippets are normally indented after insertion. To suppress indentation
add the file extension "ni" or "noindent" to the snippet file name, e.g.
parameter_handling.c.noindent
1.5.2 PICKING UP PROTOTYPES *csupport-proto*
PICK UP PROTOTYPES.
To make a prototype from a function head mark the function head and choose
'Snippets -> pick up prototype'. From the first six lines of
void
print_double_array ( double array[], /* array to print */
int n, /* number of elements to print */
int columns, /* number of elements per column */
char* arrayname /* array name */
)
{
...
} /* ---------- end of function print_double_array ---------- */
the prototype
void print_double_array ( double array[], int n, int columns, char* arrayname );
is produced and put in an internal buffer.
- Leading and trailing whitespaces are removed.
- All inner whitespaces are squeezed.
- All comments will be discarded.
- Trailing parts of the function body (e.g a '{' ) will also be removed.
- The class name and the scope resolution operator will be removed (C++ method
implementations).
Further prototypes can be picked up and gathered in the buffer.
For C++ methods namespace names and class names will be removed
(exception: 'std::' ). The first two lines of
std::string
ROBOT::Robot::get_name ( void )
{
return type_name;
} /* ----- end of method Robot::get_name ----- */
result in the prototype
std::string get_name ( void );
Folding may help picking up prototypes (see |csupport-folding|).
INSERT PROTOTYPES
With 'Snippets -> insert prototype(s)' all picked up prototypes currently in
the buffer will be inserted below the cursor.
The prototype buffer will be cleared after insertion.
DISCARD PROTOTYPES
The prototype buffer can be cleared with 'Snippets -> clear prototype(s)' .
SHOW PROTOTYPES
The list of gathered prototypes can be shown with
'Snippets -> show prototype(s)'. The number and the filename are shown, e.g.
(1) matrix.c # double** calloc_double_matrix ( int rows, int columns );
(2) matrix.c # void free_double_matrix ( double **m );
(3) foomain.c # void foo ( );
REMARK. Generating prototypes this way is nice in a small project. You may
want to use an extractor like cextract or something else.
------------------------------------------------------------------------------
1.6 MENU 'C++' *csupport-c++*
------------------------------------------------------------------------------
1.6.1 NORMAL MODE, INSERT MODE. *csupport-c++-normal-mode*
An empty statement will be inserted and in some cases properly indented. The
item 'try .. catch' will insert the following lines:
try {
}
catch ( const &ExceptObj ) { // handle exception:
}
catch (...) { // handle exception: unspezified
}
The cursor will go into the try block.
1.6.2 VISUAL MODE. *csupport-c++-visual-mode*
The highlighted area can be surrounded by one of the following statements:
try - catch
catch
catch(...)
namespace { }
extern "C" { }
The whole statement will be indented after insertion.
1.6.3 METHOD IMPLEMENTATION *csupport-c++-method-impl*
The menu item 'method implement.' asks for a method name. If this item is
called the first time you will see just an scope resolution operator. If you
specify the scope this is used the next time you call this item. If you use
one of the menu items to generate a class (see |csupport-templates|) the
scope will be extracted and used for the next method.
------------------------------------------------------------------------------
1.7 MENU 'Run' *csupport-run*
------------------------------------------------------------------------------
1.7.1 MINIMAL MAKE FUNCTIONALITY *csupport-run-buffer*
The 'Run' menu provides a minimal make functionality for single file projects
(e.g. in education) :
SAVE AND COMPILE
'save and compile' saves the buffer and run the compiler with the given
options (see |csupport-custom-glob-vars|).
An error window will be opened if the compiler reports errors and/or warnings.
Quickfix commands can now be used to jump to an error location.
Consider using maps like
map <silent> <F7> <Esc>:cp<CR>
map <silent> <F8> <Esc>:cn<CR>
in your ~/.vimrc file to jump over the error locations and make navigation
easier. The error list and the error locations in your source buffer will be
synchronized.
LINK
'link' makes an executable from the current buffer. If the buffer is not
saved, or no object is available or the object is older then the source step
'save and compile' is executed first.
The behavior of the compiler / linker is determined by the options assigned to
the variables described in |csupport-custom-glob-vars| (4.group).
RUN
'run' runs the executable with the same name (extension .e) as the current
buffer. If the buffer is not saved, or no executable is available or the
executable is older then the source steps 'save and compile' and 'link' are
executed first.
1.7.2 COMMAND LINE ARGUMENTS *csupport-run-cmdline-args*
The item 'command line arguments' calls an input dialog which asks for command
line arguments. These arguments are forwarded to the program which is run by
the 'run' item. The arguments are kept until you change them.
The arguments belong to the current buffer (that is, each buffer can have its
own arguments).
If the buffer gets a new name with "save as" the arguments will now belong to
the buffer with the new name.
The command line arguments can be followed by pipes and redirections:
11 22 | sort -rn | head -10 > out
Caveat: If you look for the current arguments by calling this menu item again
be sure to leave it with a CR (not Esc !). Due to a limitation of an internal
Vim function CR will keep the arguments, Esc with discard them.
1.7.3 RUN make *csupport-run-make*
The item 'make' runs the external make program.
1.7.4 COMMAND LINE ARGUMENTS FOR make *csupport-run-make-args*
The item 'command line arguments for make' calls an input dialog which asks
for command line arguments for make. These arguments are forwarded to make
when called by the item 'make'.
1.7.5 SPLINT *csupport-run-splint*
Splint is a tool for statically checking C programs (see http://www.splint.org).
Of course it has to be installed in order to be used within Vim. The menu
item 'Run->splint' will run the current buffer through splint.
An error window will be opened if splint has something to complain about.
Quickfix commands can now be used to jump to an error location. For easier
navigation see tip under 'SAVE AND COMPILE' |csupport-run-buffer|.
Splint has many options. Presumably the best way is to keep the options in an
option file (~/.splintrc). For a quick try you can use the menu item
'Run->cmd. line arg. for splint' to specify some buffer related options.
When vim is started this plugin will check whether splint is executable. If
not, the menu item will *NOT' be visible.
1.7.6 CODECHECK *csupport-run-codecheck*
CodeCheck (TM) is a commercial code analyzing tool produced by Abraxas
Software, Inc. (www.abraxas-software.com).
Of course it has to be installed in order to be used within Vim. The menu
item 'Run->CodeCheck' will run the current buffer through CodeCheck.
An error window will be opened if CodeCheck has something to complain about.
Quickfix commands can now be used to jump to an error location. For easier
navigation see tip under 'SAVE AND COMPILE' |csupport-run-buffer|.
CodeCheck has many options. For a quick try you can use the menu item
'Run->cmd. line arg. for CodeCheck' to specify some buffer related options.
CodeCheck will be run with default options (see |csupport-custom-glob-vars|).
The default options can be overwritten by placing a global variable in
~/.vimrc , e.g.
let g:C_CodeCheckOptions = "-K13 -Rmeyers"
The default name for the executable is 'check'. There are other names in use
on different platforms. The name can be changed by placing a global variable
in ~/.vimrc , e.g.
let g:C_CodeCheckExeName = "chknt.exe"
When vim is started this plugin will check whether CodeCheck is executable. If
not, the menu item will *NOT' be visible.
1.7.7 INDENT *csupport-run-indent*
The formatter 'indent' can be run over the whole buffer or a marked region.
Before formatting the whole buffer this buffer will be saved to disk and you
will be asked for a confirmation.
Indent has many options. These are kept in the file '.indent.pro' in your home
directory. See the indent manual for more information.
1.7.8 HARDCOPY *csupport-run-hardcopy*
Generates a PostScript file from the whole buffer or from a marked region.
On a Windows system a printer dialog is displayed.
The print header contains date and time for the current locale. The definition
used is
let s:C_Printheader = "%<%f%h%m%< %=%{strftime('%x %X')} Page %N"
The current locale can be overwritten by changing the language, e.g.
:language C
or by setting a global variable in the file ~/.vimrc , e.g. :
let g:C_Printheader = "%<%f%h%m%< %=%{strftime('%x %X')} SEITE %N"
See :h printheader and :h strftime() for more details.
1.7.9 REBUILD TEMPLATES *csupport-run-templates*
After editing one or more template files a click on this item rereads the
template files and rebuilds all templates.
1.7.10 XTERM SIZE *csupport-run-xterm*
The size of the xterm used for running a program (below) can be set by this
menu item. The default is 80 columns with 24 lines.
This feature is not available under Windows.
1.7.11 OUTPUT REDIRECTION *csupport-run-output*
Running a program can be done in one of three ways:
(1) Run the program from the gVim command line.
This is for interactive programs with little input and output.
(2) Run the program and direct the output into a window with name "C-Output".
The buffer and its content will disappear when the window is closed and
reused otherwise.
This is for non-interactive programs with little to very much output.
You have unlimited line length, regex search, navigation, ...
The tabstop value will be set to 8 for "C-Output".
(3) Run the program in an xterm.
The output method can be chosen from the menu item 'Run->output: ...'.
This menu has three states:
output: VIM->buffer->xterm
output: BUFFER->xterm->vim
output: XTERM->vim->buffer
The first (uppercase) item shows the current method. The default is 'vim'.
This can be changed by setting the variable g:C_OutputGvim to another value.
Possible values are 'vim', 'buffer' and 'xterm' .
The xterm defaults can be set in ~/.vimrc by the variable g:C_XtermDefaults .
The default is "-fa courier -fs 12 -geometry 80x24" :
font name : -fa courier
font size : -fs 12
terminal size : -geometry 80x24
See 'xterm -help' for more options. Xterms are not available under Windows.
------------------------------------------------------------------------------
1.8 'help' *csupport-help*
------------------------------------------------------------------------------
The root menu item 'help' shows this plugin help in a help window. The help
tags must have been generated with
:helptags ~/.vim/doc
==============================================================================
2. USAGE WITHOUT GUI (Vim) *csupport-usage-vim*
==============================================================================
The frequently used constructs can be inserted with key mappings. The
mappings are also described in the document c-hot-keys.pdf (reference card,
part of this package).
Hint: Typing speed matters. The combination of a leader ('\') and the
following character(s) will only be recognized for a short time.
The insert mode mappings start with ` (backtick).

The hotkeys are defined in the file type plugin c.vim (part of this csupport
plugin package) and described in the document c-hot-keys.pdf
==============================================================================
3. HOTKEYS *csupport-hotkeys*
==============================================================================
The following hotkeys are defined in normal, visual and insert mode:
F9 compile and link
Alt-F9 write buffer and compile
Ctrl-F9 run executable
Shift-F9 set command line arguments
Shift-F2 switch between source files and header files
Shift-F2 can be used to switch between source files and header files if the
plugin a.vim is present. To suppress the creation of a new header file when
switching from a source file the file ~/.vimrc should contain a line
let g:alternateNoDefaultAlternate = 1
A header file will only be opened if it already exists.
The hotkeys are defined in the file type plugin c.vim .
All hotkeys from the non-GUI mode also work for gVim (see |csupport-usage-vim|).
==============================================================================
4. CUSTOMIZATION *csupport-custom*
==============================================================================
------------------------------------------------------------------------------
4.1 GLOBAL VARIABLES *csupport-custom-glob-vars*
------------------------------------------------------------------------------
Several global variables are checked by the script to customize it:
----------------------------------------------------------------------------
GLOBAL VARIABLE DEFAULT VALUE TAG (see below)
----------------------------------------------------------------------------
g:C_GlobalTemplateFile plugin_dir.'c-support/templates/Templates'
g:C_LocalTemplateFile $HOME.'/.vim/c-support/templates/Templates'
g:C_TemplateOverwrittenMsg 'yes'
g:C_CodeSnippets plugin_dir."/c-support/codesnippets/"
g:C_Dictionary_File ""
g:C_LoadMenus "yes"
g:C_MenuHeader "yes"
g:C_OutputGvim "vim"
g:C_XtermDefaults "-fa courier -fs 12 -geometry 80x24"
g:C_Printheader "%<%f%h%m%< %=%{strftime('%x %X')} Page %N"
Linux/UNIX:
g:C_ObjExtension ".o"
g:C_ExeExtension ""
g:C_CCompiler "gcc"
g:C_CplusCompiler "g++"
Windows:
g:C_ObjExtension ".obj"
g:C_ExeExtension ".exe"
g:C_CCompiler "gcc.exe"
g:C_CplusCompiler "g++.exe"
g:C_CFlags "-Wall -g -O0 -c"
g:C_LFlags "-Wall -g -O0"
g:C_Libs "-lm"
g:C_LineEndCommColDefault 49
g:C_CExtension "c"
g:C_TypeOfH "cpp"
g:C_CodeCheckExeName "check"
g:C_CodeCheckOptions "-K13"
The variable plugin_dir will automatically be set to one of the following values:
$HOME.'/.vim/' for Linux/Unix
$VIM.'/vimfiles/' for Windows
----------------------------------------------------------------------------
1. group: g:C_GlobalTemplateFile : Sets the master template file (see|csupport-templates|)
g:C_LocalTemplateFile : Sets the local template file (see|csupport-templates|)
g:C_TemplateOverwrittenMsg : message if template is overwritten
2. group: g:C_CodeSnippets : The name of the code snippet directory
(see |csupport-snippets|).
g:C_Dictionary_File : The name(s) of the dictionary file(s) used for
word completion (see also |csupport-dictionary|)
g:C_Root : the name of the root menu of this plugin
g:C_LoadMenus : Load menus and mappings ("yes", "no") at startup.
g:C_MenuHeader : Switch the submenu header on/off.
g:C_OutputGvim : when program is running output goes to the vim
command line ("vim"), to a buffer ("buffer") or to
an xterm ("xterm").
g:C_XtermDefaults : the xterm defaults
g:C_Printheader : hardcopy: definition of the page header
3. group: g:C_CExtension : Extension of C files. Everything else is C++.
g:C_TypeOfH : filetype of header files with extension 'h' (c,cpp)
(see |csupport-comm-style|)
g:C_CCompiler : The name of the C compiler.
g:C_CplusCompiler : The name of the C++ compiler.
g:C_CFlags : Compiler flags used for a compilation.
g:C_LFlags : Compiler flags used for linkage.
g:C_Libs : Libraries to link with.
g:C_ObjExtension : C/C+ file extension for objects
(leading point required if not empty)
g:C_ExeExtension : C/C+ file extension for executables
(leading point required if not empty)
g:C_LineEndCommColDefault : Default starting column for end-of-line comments.
g:C_CodeCheckExeName : The name of the CodeCheck (TM) executable
(the default is 'check')
g:C_CodeCheckOptions : Default options for CodeCheck (TM)
(see |csupport-run-codecheck|).
To override the default add appropriate assignments to ~/.vimrc .
------------------------------------------------------------------------------
4.2 THE ROOT MENU *csupport-custom-root-menu*
------------------------------------------------------------------------------
The variable g:C_Root, if set (in ~/.vimrc or in ~/.gvimrc), gives the name of
the single Vim root menu item in which the C/C++ submenus will be put. The
default is
'&C\/C\+\+.'
Note the terminating dot. A single root menu can be used if the screen is
limited or several plugins are used in parallel.
If set to "", this single root menu item will not appear. Now all submenus
are put into the Vim root menu. This is nice for beginners in a lab
installation or for C-only programmers.
------------------------------------------------------------------------------
4.3 SYSTEM-WIDE INSTALLATION *csupport-system-wide*
------------------------------------------------------------------------------
A system-wide installation (one installation for all users) is done as
follows.
As *** SUPERUSER *** :
(1) Find the Vim installation directory.
The Vim ex command ':echo $VIM' gives '/usr/local/share/vim' or something like
that. Beyond this directory you will find the Vim installation, e.g. in
'/usr/local/share/vim/vim71' if Vim version 7.1 has been installed.
(2) Create a new subdirectory 'vimfiles', e.g. '/usr/local/share/vim/vimfiles'.
(3) Install C/C++ Support
Copy the archive cvim.zip to this new directory and unpack it:
unzip cvim.zip
(4) Generate the help tags:
:helptags $VIM/vimfiles/doc
As *** USER *** :
Create your private snippet directory:
mkdir --parents ~/.vim/c-support/codesnippets
You may want to copy the snippets comming with this plugin (in
$VIM/vimfiles/c-support/codesnippets) into the new directory or to set a
link to the global directory.
Create your private template directory:
mkdir --parents ~/.vim/c-support/template
Create a private template file 'Templates' in this directory to overwrite some
macros, e.g.
*|AUTHOR|* = your name
*|AUTHORREF|* = ...
*|EMAIL|* = ...
*|COMPANY|* = ...
*|COPYRIGHT|* = ...
You can also have local templates which overwrite the global ones. To suppress
the messages in this case set a global variable in '~/.vimrc' :
let g:C_TemplateOverwrittenMsg= 'no'
The default is 'yes'.
==============================================================================
5. TEMPLATE FILES AND TAGS *csupport-templates*
==============================================================================
------------------------------------------------------------------------------
5.1 TEMPLATE FILES *csupport-templates-files*
------------------------------------------------------------------------------
Nearly all menu entries insert code snippets or comments. All these stuff is
taken from template files and can be changed by the user to meet his
requirements.
The master template file is '$HOME/.vim/c-support/templates/Templates' for a
user installation and '$VIM/vimfiles/c-support/templates/Templates' for a
system-wide installation (see|csupport-system-wide|).
The master template file starts with a macro section followed by templates for
single menu items or better by including other template files grouping the
templates according to the menu structure of this plugin. The master file
could look like this:
$
$ =============================================================
$ ========== USER MACROS ======================================
$ =============================================================
$
*|AUTHOR|* = Dr. Fritz Mehner
*|AUTHORREF|* = mn
*|EMAIL|* = mehner@fh-swf.de
*|COMPANY|* = FH Südwestfalen, Iserlohn
*|COPYRIGHT|* = Copyright (c)*|YEAR|, |AUTHOR|*
$
$ =============================================================
$ ========== FILE INCLUDES ====================================
$ =============================================================
$
*|includefile|* = c.comments.template
*|includefile|* = c.cpp.template
*|includefile|* = c.idioms.template
*|includefile|* = c.preprocessor.template
*|includefile|* = c.statements.template
Lines starting with a dollar sign are comments. The section starting
with *|AUTHOR|* assigns values to predefined tags
(see|csupport-templates-macros|) to personalize some templates. Other
predefined tags with given default values can be used (e.g. *|YEAR|* ).
User defined tags are possible. They have the following syntax:
*|macroname|* = replacement
A macroname starts with a letter (uppercase or lowercase) followed by zero or
more letters, digits or underscores.
------------------------------------------------------------------------------
5.2 MACROS *csupport-templates-macros*
------------------------------------------------------------------------------
The following macro names are predefined. The first group is used to
personalize templates.
----------------------------------------------------------------------------
PREDEFINED MACROS DEFAULT VALUE
----------------------------------------------------------------------------
*|AUTHOR|* ""
*|AUTHORREF|* ""
*|EMAIL|* ""
*|COMPANY|* ""
*|PROJECT|* ""
*|COPYRIGHTHOLDER|* ""
*|includefile|* ""
*|BASENAME|* filename without path and suffix
*|DATE|* the preferred date representation for the current locale
without the time
*|FILENAME|* filename without path
*|PATH|* path without filename
*|SUFFIX|* filename suffix
*|TIME|* the preferred time representation for the current locale
without the date and the time zone or name or abbreviation
*|YEAR|* the year as a decimal number including the century
*|includefile|* can be used to include an additional template file. A file
will be included only once. Commenting and uncommenting include macros is a
simple way to switch between several sets of templates (see also
|csupport-run-templates|). Overwriting existing macros and templates is
possible.
----------------------------------------------------------------------------
PREDEFINED TAGS
----------------------------------------------------------------------------
<CURSOR> The cursor position after insertion of a template
<SPLIT> The split point when inserting in visual mode
(see|csupport-templates-definition|)
A dependent template file can start with its own macro section. There is no
need to have all user defined macros in the master file.
When the first template definition is found (see below) macro definitions are
no longer recognized.
----------------------------------------------------------------------------
USER DEFINED FORMATS FOR DATE AND TIME *csupport-templates-date*
----------------------------------------------------------------------------
The format for *|DATE|* ,*|TIME|* , and*|YEAR|* can be set by the user. The
defaults are
*|DATE|* '%x'
*|TIME|* '%X'
*|YEAR|* '%Y'
See the manual page of the C function strftime() for the format. The accepted
format depends on your system, thus this is not portable! The maximum length
of the result is 80 characters.
User defined formats can be set using the following global variables in
~/.vimrc , e.g.
let g:C_FormatDate = '%D'
let g:C_FormatTime = '%H:%M'
let g:C_FormatYear = 'year %Y'
------------------------------------------------------------------------------
5.3 TEMPLATES *csupport-templates-names*
------------------------------------------------------------------------------
5.3.1 Template names
The template behind a menu entry is identified by a given name. The first part
of the name identifies the menu, the second part identifies the item. The
modes are also hard coded (see|csupport-templates-definition|for the use of
<SPLIT>).

5.3.2 Template definition *csupport-templates-definition*
A template definition starts with a template head line with the following
syntax:
== templatename == [ position == ]
The templatename is one of the above template identifiers. The position
attribute is optional. Possible attribute values are:
above insert the template before the current line
append append the template to the current line
below insert the template below the current line
insert insert the template at the cursor position
start insert the template before the first line of the buffer
An example:
== comment.function ==
/*
* === FUNCTION =======================================================
* Name: <CURSOR>
* Description:
* ======================================================================
*/
The definition of a template ends at the next head line or at the end of the
file.
Templates for the visual mode can use <SPLIT>. The text before <SPLIT> will
than be inserted above the marked area, the text after <SPLIT> will be
inserted behind the marked area. An example:
== statements.if-block-else ==
if ( <CURSOR> ) {
<SPLIT>} else {
}
If applied to the marked block
xxxxxxxxxxx
xxxxxxxxxxx
this template yields
if ( ) {
xxxxxxxxxxx
xxxxxxxxxxx
} else {
}
The templates with a visual mode are shown in the table under
|csupport-templates-names|.
5.3.3 Template expansion *csupport-templates-expansion*
There are additional ways to control the expansion of a template.
USER INPUT
----------
If the usage of a yet undefined user macro starts with a question mark the
user will be asked for the replacement first, e.g. with the following template
== idioms.function ==
void<CURSOR>
*|?FUNCTION_NAME|* ( )
{
<SPLIT> return ;
} /* ----- end of function*|FUNCTION_NAME|* ----- */
The can specify the function name which then will be applied twice. If the
macro was already in use the old value will be suggested as default.
MACRO MANIPULATION
------------------
A macro expansion can be controlled by the following attributes
:l change macro text to lowercase
:u change macro text to uppercase
:c capitalize macro text
:L legalize name
The include guard template is an example for the use of ':L' :
== preprocessor.ifndef-def-endif ==
#ifndef *|?BASENAME:L|_INC*
#define *|BASENAME|_INC*
<CURSOR><SPLIT>
#endif // ----- #ifndef*|BASENAME|_INC* -----
The base name of the file shall be used as part of the include guard name.
The predefined macro*|BASENAME|* is used to ask for this part because this
macro has already a defined value. That value can accepted or replaced by the
user. For the filename 'test test++test.h' the legalized base name
'TEST_TEST_TEST' will be suggested.
Legalization means:
- replace all whitespaces by underscores
- replace all non-word characters by underscores
- replace '+' and '-' by underscore
==============================================================================
6. C/C++ DICTIONARY *csupport-dictionary*
==============================================================================
The files
c-c++-keywords.list
k+r.list
stl_index.list
are a part of this plugin and can be used (together with your own lists) as
dictionaries for automatic word completion. This feature is enabled by
default. The default word lists are
plugin_dir/c-support/wordlists/c-c++-keywords.list
plugin_dir/c-support/wordlists/k+r.list
plugin_dir/c-support/wordlists/stl_index.list
The variable plugin_dir will automatically be set by the plugin to one of the
following values:
$HOME.'/.vim/' for Linux/Unix
$VIM.'/vimfiles/' for Windows
If you want to use an additional list MyC.list put the following lines into
~/.vimrc :
let g:C_Dictionary_File = PLUGIN_DIR.'/c-support/wordlists/c-c++-keywords.list,'.
\ PLUGIN_DIR.'/c-support/wordlists/k+r.list,'.
\ PLUGIN_DIR.'/c-support/wordlists/stl_index.list,'.
\ PLUGIN_DIR.'/c-support/wordlists/MyC.list'
When in file ~/.vimrc the name PLUGIN_DIR has to be replaced by $HOME or
$VIM (see above). Whitespaces in the pathnames have to be escaped with a
backslash.
The right side is a comma separated list of files. Note the point at the end
of the first line (string concatenation) and the backslash in front of the
second line (continuation line).
You can use Vim's dictionary feature CTRL-X, CTRL-K (and CTRL-P, CTRL-N).
==============================================================================
7. EXTEND taglist.vim FOR make AND qmake *csupport-taglist*
==============================================================================
The use of the Vim plugin taglist.vim (Author: Yegappan Lakshmanan) is highly
recommended. It uses the program ctags which generates tag files for 3 dozen
languages (Exuberant Ctags, Darren Hiebert, http://ctags.sourceforge.net).
With the following extensions the list of targets in a makefile can be shown
in the taglist window.
1) Append the file customization.ctags to the file $HOME/.ctags .
2) Add the following lines (from customization.vimrc) to $HOME/.vimrc :
"
"-------------------------------------------------------------------
" taglist.vim : toggle the taglist window
" taglist.vim : define the title texts for make
" taglist.vim : define the title texts for qmake
"-------------------------------------------------------------------
noremap <silent> <F11> <Esc><Esc>:Tlist<CR>
inoremap <silent> <F11> <Esc><Esc>:Tlist<CR>
let tlist_make_settings = 'make;m:makros;t:targets'
let tlist_qmake_settings = 'qmake;t:SystemVariables'
if has("autocmd")
" ---------- qmake : set file type for *.pro ----------
autocmd BufNewFile,BufRead *.pro set filetype=qmake
endif " has("autocmd")
3) restart vim/gvim
The two maps will toggle the taglist window (hotkey F11) in all editing modes.
The two assignments define the headings for the (q)make sections in the
taglist window. The autocmd set the file type 'qmake' for the filename
extension 'pro' (ctags needs this).
==============================================================================
8. SYNTAX BASED FOLDING *csupport-folding*
==============================================================================
Syntax based folding can be enabled by adding the following lines to the file
'~/.vim/syntax/c.vim':
syn region cBlock start="{" end="}" transparent fold
set foldmethod=syntax
" initially all folds open:
set foldlevel=999
You may have to create this file first. See |folding| for more information.
==============================================================================
9. WINDOWS PARTICULARITIES *csupport-windows*
==============================================================================
The plugin should go into the directory structure below the local
installation directory $HOME/.vim/ for LINUX/UNIX and $VIM/vimfiles/ for
Windows.
The values of the two variables can be found from inside Vim:
:echo $VIM
or
:echo $HOME
Configuration files:
LINUX/UNIX : $HOME/.vimrc and $HOME/.gvimrc
Windows : $VIM/_vimrc and $VIM/_gvimrc
Compiler settings:
It could be necessary to add further settings for your compiler. To compile
C++-programs using a Dev-C++ installation (http://www.bloodshed.net) the
following item in $VIM/_vimrc is needed (depends on the Dev-C++ install
directory):
let g:C_CFlags = '-Wall -g -o0 -c -I c:\programs\dev-c++\include\g++'
==============================================================================
10. TROUBLESHOOTING *csupport-troubleshooting*
==============================================================================
* I do not see any new main menu item.
- Was the archive extracted into the right directory?
* How can I see what was loaded?
- Use ':scriptnames' from the Vim command line.
* No main menu item.
- Loading of plugin files must be enabled. If not use
:filetype plugin on
This is the minimal content of the file '$HOME/.vimrc'. Create one if there
is none, or better use customization.vimrc.
* Most key mappings do not work.
- They are defined in a filetype plugin in '$HOME/.vim/ftplugin/'. Use ':filetype'
to check if filetype plugins are enabled. If not, add the line
filetype plugin on
to the file '~/.vimrc'.
* Some hotkeys do not work.
- The hotkeys might be in use by your graphical desktop environment.
Under KDE Ctrl-F9 is the hotkey which let you switch to the 9. desktop.
The key settings can usually be redefined.
* Splint and/or CodeCheck menu item not visible.
- The program is not installed or not found (path not set) or not executable.
==============================================================================
