Extra Plug-ins |ada-extra-plugins| + +============================================================================== +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 +file is opened and 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 information (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 information 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 its own multi-language code parser. The parser is quite +fast, produces a lot of extra information (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 than 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 versions available which differ 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 be 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_Program| + + *g:gnat.Find()* +g:gnat.Find() + Calls |g:gnat.Find_Program| + + *g:gnat.Tags()* +g:gnat.Tags() + 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 + External command used for |g:gnat.Make()| (|'makeprg'|). + + *g:gnat.Pretty_Program* +g:gnat.Pretty_Program string + External command used for |g:gnat.Pretty()| + + *g:gnat.Find_Program* +g:gnat.Find_Program string + External command used for |g:gnat.Find()| + + *g:gnat.Tags_Command* +g:gnat.Tags_Command string + External command used for |g:gnat.Tags()| + + *g:gnat.Error_Format* +g:gnat.Error_Format string + Error format (|'errorformat'|) + +------------------------------------------------------------------------------ +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 as a parameter. The compiler plug-in supports the usual file name +convention to convert the file into a unit name. Both '-' and '__' are allowed +as separators. + + *decada_members* +DEC ADA OBJECT ~ + + *g:decada.Make()* +g:decada.Make() function + Calls |g:decada.Make_Command| and displays the result inside a + |quickfix| window. + + *g:decada.Unit_Name()* +g:decada.Unit_Name() function + Get the Unit name for the current file. + + *g:decada.Make_Command* +g:decada.Make_Command string + External command used for |g:decada.Make()| (|'makeprg'|). + + *g:decada.Error_Format* +g:decada.Error_Format string + Error format (|'errorformat'|). + +============================================================================== +5.
