+
+==============================================================================
+1. Syntax Highlighting ~
+							       *ft-ada-syntax*
+
+This mode is designed for the 2005 edition of Ada ("Ada 2005"), which includes
+support for objected-programming, protected types, and so on.  It handles code
+written for the original Ada language ("Ada83", "Ada87", "Ada95") as well,
+though code which uses Ada 2005-only keywords will be wrongly colored (such
+code should be fixed anyway).  For more information about Ada, see
+http://www.adapower.com.
+
+The Ada mode handles a number of situations cleanly.
+
+For example, it knows that the "-" in "-5" is a number, but the same character
+in "A-5" is an operator.  Normally, a "with" or "use" clause referencing
+another compilation unit is coloured the same way as C's "#include" is coloured.
+If you have "Conditional" or "Repeat" groups coloured differently, then "end
+if" and "end loop" will be coloured as part of those respective groups.
+
+You can set these to different colours using vim's "highlight" command (e.g.,
+to change how loops are displayed, enter the command ":hi Repeat" followed by
+the colour specification; on simple terminals the colour specification
+ctermfg=White often shows well).
+
+There are several options you can select in this Ada mode. See|ft-ada-options|
+for a complete list.
+
+To enable them, assign a value to the option.  For example, to turn one on:
+ >
+    > let g:ada_standard_types = 1
+>
+To disable them use ":unlet".  Example:
+>
+    > unlet g:ada_standard_types
+
+You can just use ":" and type these into the command line to set these
+temporarily before loading an Ada file.  You can make these option settings
+permanent by adding the "let" command(s), without a colon, to your "~/.vimrc"
+file.
+
+Even on a slow (90Mhz) PC this mode works quickly, but if you find the
+performance unacceptable, turn on |g:ada_withuse_ordinary|.
+
+Syntax folding instructions (|fold-syntax|) are added when |g:ada_folding| is
+set.
+
+==============================================================================
+2. File type Plug-in ~
+					       *ft-ada-indent* *ft-ada-plugin*
+
+The Ada plug-in provides support for:
+
+ - auto indenting	(|indent.txt|)
+ - insert completion	(|i_CTRL-N|)
+ - user completion	(|i_CTRL-X_CTRL-U|)
+ - tag searches		(|tagsrch.txt|)
+ - Quick Fix		(|quickfix.txt|)
+ - backspace handling	(|'backspace'|)
+ - comment handling	(|'comments'|, |'commentstring'|)
+
+The plug-in only activates the features of the Ada mode whenever an Ada
+files is opened and add adds Ada related entries to the main and pop-up menu.
+
+==============================================================================
+3. Omni Completion ~
+								 *ft-ada-omni*
+
+The Ada omni-completions (|i_CTRL-X_CTRL-O|) uses tags database created either
+by "gnat xref -v" or the "exuberant Ctags (http://ctags.sourceforge.net).  The
+complete function will automatically detect which tool was used to create the
+tags file.
+
+------------------------------------------------------------------------------
+3.1 Omni Completion with "gnat xref" ~
+								   *gnat-xref*
+
+GNAT XREF uses the compiler internal informations (ali-files) to produce the
+tags file. This has the advantage to be 100% correct and the option of deep
+nested analysis. However the code must compile, the generator is quite
+slow and the created tags file contains only the basic Ctags informations for
+each entry - not enough for some of the more advanced Vim code browser
+plug-ins.
+
+NOTE: "gnat xref -v" is very tricky to use as it has almost no diagnostic
+       output - If nothing is printed then usually the parameters are wrong.
+       Here some important tips:
+
+1)  You need to compile your code first and use the "-aO" option to point to
+    your .ali files.
+2)  "gnat xref -v ../Include/adacl.ads" won't work - use  the "gnat xref -v
+    -aI../Include adacl.ads" instead.
+3)  "gnat xref -v -aI../Include *.ad?" won't work - use "cd ../Include" and
+    then "gnat xref -v *.ad?"
+4)  Project manager support is completely broken - don't even try "gnat xref
+    -Padacl.gpr".
+5)  VIM is faster when the tags file is sorted - use "sort --unique
+    --ignore-case --output=tags tags" .
+6)  Remember to insert "!_TAG_FILE_SORTED 2 %sort ui" as first line to mark
+    the file assorted.
+
+------------------------------------------------------------------------------
+3.2 Omni Completion with "ctags"~
+								   *ada-ctags*
+
+Exuberant Ctags uses it's own multi-language code parser. The parser is quite
+fast, produces a lot of extra informations (hence the name "Exuberant Ctags")
+and can run on files which currently do not compile.
+
+There are also lots of other Vim-tools which use exuberant Ctags.
+
+You will need to install a version of the Exuberant Ctags which has Ada
+support patched in. Such a version is available from the GNU Ada Project
+(http://gnuada.sourceforge.net).
+
+The Ada parser for Exuberant Ctags is fairly new - don't expect complete
+support yet.
+
+==============================================================================
+4.  Compiler Support ~
+								*ada-compiler*
+
+The Ada mode supports more then one Ada compiler and will automatically load the
+compiler set in|g:ada_default_compiler|whenever an Ada source is opened. The
+provided compiler plug-ins are split into the actual compiler plug-in and a
+collection of support functions and variables. This allows the easy
+development of specialized compiler plug-ins fine tuned to your development
+environment.
+
+------------------------------------------------------------------------------
+4.1 GNAT ~
+							       *compiler-gnat*
+
+GNAT is the only free (beer and speech) Ada compiler available. There are
+several version available which differentiate in the licence terms used.
+
+The GNAT compiler plug-in will perform a compile on pressing <F7> and then
+immediately shows the result. You can set the project file to be used by
+setting:
+ >
+ > call g:gnat.Set_Project_File ('my_project.gpr')
+
+Setting a project file will also create a Vim session (|views-sessions|) so -
+like with the GPS - opened files, window positions etc. will remembered
+separately for all projects.
+
+								*gnat_members*
+GNAT OBJECT ~
+
+							       *g:gnat.Make()*
+g:gnat.Make()
+		Calls|g:gnat.Make_Command|and displays the result inside a
+               |quickfix| window.
+
+							     *g:gnat.Pretty()*
+g:gnat.Pretty()
+		Calls|g:gnat.Pretty_Command|

+		Calls|g:gnat.Tags_Command|
+
+						   *g:gnat.Set_Project_File()*
+g:gnat.Set_Project_File([{file}])
+		Set gnat project file and load associated session.  An open
+		project will be closed and the session written.  If called
+		without file name the file selector opens for selection of a
+		project file. If called with an empty string then the project
+		and associated session are closed.
+
+							 *g:gnat.Project_File*
+g:gnat.Project_File	string
+		Current project file.
+
+							 *g:gnat.Make_Command*
+g:gnat.Make_Command	string

+
+------------------------------------------------------------------------------
+4.2 Dec Ada ~
+					    *compiler-hpada* *compiler-decada*
+					*compiler-vaxada* *compiler-compaqada*
+
+Dec Ada (also known by - in chronological order - VAX Ada, Dec Ada, Compaq Ada
+and HP Ada) is a fairly dated Ada 83 compiler. Support is basic: <F7> will
+compile the current unit.
+
+The Dec Ada compiler expects the package name and not the file name to be
+passed a parameter. The compiler plug-in supports the usual file name
+convention to convert the file into a unit name. For separates both '-' and
+'__' are allowed.
+
+							      *decada_members*
+DEC ADA OBJECT ~
+
+							     *g:decada.Make()*

+		by the various completion methods.
+
+						      *g:ada_withuse_ordinary*
+g:ada_withuse_ordinary	  bool (true when exists)
+		Show "with" and "use" as ordinary keywords (when used to

+
+						   *g:ada_extended_completion*
+g:ada_extended_completion
+		Uses extended completion for <C-N> and <C-R> completions
+		(|i_CTRL-N|). In this mode the '.' is used as part of the

+8. Extra Plugins ~
+							   *ada-extra-plugins*
+
+You can optionally install the following extra plug-in. They work well with Ada
+and enhance the ability of the Ada mode.:
+
+backup.vim
+	http://www.vim.org/scripts/script.php?script_id=1537
+	Keeps as many backups as you like so you don't have to.
+
+rainbow_parenthsis.vim
+	http://www.vim.org/scripts/script.php?script_id=1561
+	Very helpful since Ada uses only '(' and ')'.
+
+nerd_comments.vim
+	http://www.vim.org/scripts/script.php?script_id=1218
+	Excellent commenting and uncommenting support for almost any
+	programming language.
+
+matchit.vim
+	http://www.vim.org/scripts/script.php?script_id=39
+	'%' jumping for any language. The normal '%' jump only works for '{}'
+	style languages. The Ada mode will set the needed search patters.
+
+taglist.vim
+	http://www.vim.org/scripts/script.php?script_id=273
+	Source code explorer sidebar. There is a patch for Ada available.
+
+The GNU Ada Project distribution (http://gnuada.sourceforge.net) of Vim
+contains all of the above.
