70 @ede{} is the Emacs Development Environment: an Emacs extension that
71 simplifies building and debugging programs in Emacs. It attempts to
72 emulate a typical IDE (Integrated Development Environment). @ede{}
73 can manage or create your makefiles and other building environment
74 duties, allowing you to concentrate on writing code rather than
75 support files. It aims to make it much easier for new programmers to
76 learn and adopt GNU ways of doing things.

94 @chapter @ede{} Project Concepts
96 @ede{} is a generic interface for managing projects. It specifies a
97 single set of menus and keybindings, while supporting multiple ways to
98 express a project via a build system.
100 In the subsequent chapters, we will describe the different project
101 types (@pxref{Creating a project}), as well as the commands to build
102 and debug projects (@pxref{Building and Debugging}).
104 In @ede{}, a project hierarchy matches a directory hierarchy. The
105 project's topmost directory is called the @dfn{project root}, and its
106 subdirectories are @dfn{subprojects}.
108 Each project can contain multiple @dfn{targets}. A target, at the
109 simplest level, is a named collection of files within a project. A
110 target can specify two different types of information:
114 A collection of files to be added to a distribution (e.g., a tarball
115 that you intend to distribute to others).
118 A collection of files that can be built into something else (e.g., a
119 program or compiled documentation).
122 Lastly, @ede{} provides a way for other tools to easily learn file
123 associations. For example, a program might need to restrict some sort
124 of search to files in a single target, or to discover the location of
125 documentation or interface files. @ede{} can provide this
128 @node EDE Mode, Creating a project, EDE Project Concepts, top
131 @ede{} is implemented as a minor mode, which augments other modes such
132 as C mode, and Texinfo mode. You can enable @ede{} for all buffers by
133 running the command @code{global-ede-mode}, or by putting this in your
140 Activating @ede{} adds a menu named @samp{Development} to the menu
141 bar. This menu provides several menu items for high-level @ede{}
142 commands. These menu items, and their corresponding keybindings, are
143 independent of the type of project you are actually working on.
145 @node Creating a project, Modifying your project, EDE Mode, top
146 @chapter Creating a project
148 To create a new project, first visit a file that you want to include
149 in that project. If you have a hierarchy of directories, first visit
150 a file in the topmost directory. From this buffer, type @kbd{M-x
151 ede-new}, or click on the @samp{Create Project} item in the
152 @samp{Development} menu.
154 The @command{ede-new} command prompts for the type of project you
155 would like to create. Each project type has its own benefits or
156 language specific enhancements. @ede{} supports four different
157 project types: @samp{Make}, @samp{Automake}, @samp{direct Automake},
162 For the @samp{Make} project type, @ede{} creates a @dfn{project file},
163 called @file{Project.ede}, in each project directory. Information
164 about the project is stored in this file. This project autogenerates
168 For the @samp{Automake} project type, @ede{} creates a
169 @file{Project.ede} project file similar to a @samp{Make} project.
170 Unlike a @samp{Make} project, this project autogenerates a
171 @file{Makefile.am} file. @ede{} handles the Automake bootstrapping
172 routines, which import and maintain a @file{configure.am} script and
173 other required files.
176 For the @samp{direct Automake} project type, @ede{} reads directly
177 from the Automake files.
179 You cannot create direct Automake projects with the @command{ede-new}
180 command. Instead, when you visit a project with existing Automake
181 files, @ede{} automatically detects them.
184 The @samp{Simple} project type provides light-weight constructs for
185 identifying a project root and looking up files. If you already have
186 a non-@ede{} project infrastructure, you can use a @samp{Simple}
187 project to provide other Emacs packages, such as Semantic, with some
188 information about the project. @xref{Simple projects}.
191 A subproject is merely a project in a subdirectory of another project.
192 You can create a subproject by using the @command{ede-new} command (or
193 the @samp{Create Project} menu item), while visiting a buffer in a
194 subdirectory of the project root. This new project is automatically
195 added to the parent project, and will be automatically loaded when
196 @ede{} reads the parent project.
198 When using a project command that involves a makefile, @ede{} uses
199 the top-most project's makefile as a starting place for the build. How
200 the toplevel project handles subprojects in the build process is
201 dependent on that project's type.

204 @chapter Modifying your project
206 In this chapter, we describe the generic features for manipulating
207 projects, including the targets and files within them. Subsequent
208 chapters, which describe specific project types, will provide more
209 detailed information about exactly what these features do.

215 * EDE Project Features::
218 @node Add/Remove target, Add/Remove files, Modifying your project, Modifying your project
219 @section Add/Remove target
221 To create a new target, type @kbd{C-c . t} (@code{ede-new-target}) or
222 use the @samp{Add Target} menu item in the @samp{Project Options}
223 submenu. This prompts for a target name, and adds the current buffer
226 The @command{ede-new-target} command also prompts for a @dfn{target
227 type}. Each target type has its own build process and class of files
230 To remove a target from the project, type @kbd{M-x ede-delete-target},
231 or use the @samp{Remove Target} menu item in the @samp{Project
234 @node Add/Remove files, Customize Features, Add/Remove target, Modifying your project
235 @section Add/Remove files
237 To add the current file to an existing target, type @kbd{C-c . a}
238 (@code{ede-add-file}), or use the @samp{Add File} menu item in the
239 @samp{Target Options} submenu.
241 You can add a file to more than one target; this is OK.
243 To remove the current file from a target, type @kbd{C-c . d}
244 (@code{ede-remove-file}), or or use the @samp{Remove File} menu item
245 in the @samp{Target Options} submenu. If the file belongs to multiple
246 targets, this command prompts for each target it could be removed
249 While working in a project, if you visit a file that is not part of an
250 existing target, @ede{} automatically prompts for a target. If you do
251 not wish to add the file to any target, you can choose @samp{none}.
252 You can customize this behavior with the variable
253 @command{ede-auto-add-method}.
255 @node Customize Features, EDE Project Features, Add/Remove files, Modifying your project
256 @section Customize Features
258 A project, and its targets, are objects using the @samp{EIEIO} object
259 system. @xref{Top,,,eieio,EIEIO manual}. These objects have data
260 fields containing important information related to your work.
262 If the high-level functions aren't enough, you can tweak all
263 user-customizable fields at any time by running the command
264 @command{customize-project} or @command{customize-target}. This loads
265 the current project or target into a customization buffer, where you
266 can tweak individual slots. This is usually necessary for complex
269 Some project modes do not have a project file, but directly read a
270 Makefile or other existing file. Instead of directly editing the
271 object, you can edit the file by typine @kbd{C-c . e}
272 (@code{ede-edit-file-target}). You should ``rescan'' the project
273 afterwards (@pxref{Miscellaneous commands}).
275 @node EDE Project Features, , Customize Features, Modifying your project
276 @section EDE Project Features
278 This section details user facing features of an @ede{} @samp{Make}
279 style project. An @samp{Automake} project has similar options (but a
280 direct Automake project does not).
282 To modify any of the specific features mentioned here, you need to
283 customize the project or target with @command{customize-project} or
284 @command{customize-target}.
286 When you are customizing, you are directly manipulating slot values in
287 @eieio{} objects. @xref{Extending EDE}, if you are interested in
291 * Changing Compilers and Flags::
295 @node Changing Compilers and Flags, Configurations, EDE Project Features, EDE Project Features
296 @subsection Changing Compilers and Flags
298 Targets that build stuff need compilers. To change compilers, you
299 need to customize the desired target.
301 In the @samp{[Make]} section, you can choose a new compiler or linker
302 from the list. If a linker you need is not available, you will need
303 to create a new one. @xref{Compiler and Linker objects}.
305 If an existing compiler or linker is close, but you need to modify
306 some flag set such as adding an include path you will need to add a
307 configuration variable.
309 To start, you should create the basic setup, and construct a makefile
310 with @command{ede-proj-regenerate}. Look in the @file{Makefile} to
311 see what commands are inserted. Once you have determined the variable
312 you need to modify, you can add a configuration for it.
313 @xref{Configurations}.
315 @node Configurations, , Changing Compilers and Flags, EDE Project Features
316 @subsection Configurations
318 Configurations specify different ways to build a project. For
319 example, you may configure a project to be in ``debug'' mode, or
320 perhaps in ``release'' mode.
322 The project, and each target type all have a slot named
323 @code{configuration-variables}. To add new variables to a
324 configuration find this slot in the custom buffer, and insert a new
325 configuration. Name it either ``debug'' or ``release'', then insert
326 some number of name/value pairs to it.
328 You can have any number of valid configurations too. To add a new
329 configuration, customize your project. Work in the @samp{[Settings]}
330 block for ``configurations''. Add a new named configuration here.
332 To switch between different active configurations, modify the
333 ``configuration default'' slot.

338 @ede{} provides the following ``project-aware'' compilation and
343 Compile the current target (@code{ede-compile-target}).
345 Compile the entire project (@code{ede-compile-project}).
347 Debug the current target (@code{ede-debug-target}).
348 @item M-x ede-make-dist
349 Build a distribution file for your project.
352 These commands are also available from the @samp{Development} menu.
354 @node Miscellaneous commands, Simple projects, Building and Debugging, top
355 @chapter Miscellaneous commands
357 If you opt to go in and edit @ede{} project files directly---for
358 instance, by using @kbd{C-c . e} (@pxref{Customize Features})---you
359 must then ``rescan'' the project files to update the internal data
360 structures. To rescan the current project, type @kbd{C-c . g}
361 (@code{ede-rescan-toplevel}).
363 @ede{} can help you find files in your project, via the command
364 @kbd{C-c . f} (@code{ede-find-file}). This prompts for a file name;
365 you need not specify the directory. EDE then tries to visit a file
366 with that name somewhere in your project.
368 @ede{} can use external tools to help with file finding. To do this,
369 customize @code{ede-locate-setup-options}.
371 @defvar ede-locate-setup-options
372 @anchor{ede-locate-setup-options}
373 List of locate objects to try out by default.
374 Listed in order of preference. If the first item cannot be used in
375 a particular project, then the next one is tried.
376 It is always assumed that @dfn{ede-locate-base} is at end of the list.
379 @ede{} also provides a project display mode for the speedbar
380 (@pxref{Speedbar,,,emacs,GNU Emacs Manual}). This allows you to view
381 your source files as they are structured in your project: as a
382 hierarchical tree, grouped according to target.
384 To activate the speedbar in this mode, type @kbd{C-c . s}
385 (@code{ede-speedbar}).
387 @node Simple projects, Extending EDE, Miscellaneous commands, top
388 @section Simple Projects
390 There is a wide array of Simple projects. The root for simple
391 projects is the class @code{ede-simple-project}. This handles the
392 infrastructure of storing a .ede file if needed.
394 The class @code{ede-simple-project} is designed to be subclassed.
395 Then key @ede{} methods can be overridden to provide a quick wrapper
398 A second project type is @code{ede-cpp-root}. This project type is
399 designed to be created for a directory hierarchy full of C/C++ code.
400 It can be configured with minimal lisp knowledge to do header file
401 lookup for @semantic{}, improving code completion performance.
404 * ede-cpp-root:: This project marks the root of a C/C++ code project.
405 * ede-simple subclassing:: Create your own simple project.

407 * ede-linux:: A project for working with Linux kernels.
408 * Custom Locate:: Customizing how to locate files in a simple project
412 @subsection ede-cpp-root
414 The @code{ede-cpp-root} project type allows you to create a single
415 object with no save-file in your @file{.emacs} file. It allows @ede{}
416 to provide the @semantic{} package with the ability to find header
419 The @code{ede-cpp-root} class knows a few things about C++ projects,
420 such as the prevalence of "include" directories, and typical
421 file-layout stuff. If this isn't sufficient, you can subclass
422 @code{ede-cpp-root-project} and add your own tweaks in just a few
423 lines. See the end of this file for an example.
425 In the most basic case, add this to your @file{.emacs} file, modifying
426 appropriate bits as needed.
429 (ede-cpp-root-project "SOMENAME" :file "/dir/to/some/file")
432 Replace @var{SOMENAME} with whatever name you want, and the filename
433 to an actual file at the root of your project. It might be a
434 Makefile, a README file. Whatever. It doesn't matter. It's just a
435 key to hang the rest of @ede{} off of.
437 The most likely reason to create this project, is to speed up
438 searching for includes files, or to simplify bootstrapping @semantic{}'s
439 ability to find files without much user interaction. In conjunction
440 with @semantic{} completion, having a short include path is key. You can
441 override the default include path and system include path like this:
444 (ede-cpp-root-project "NAME" :file "FILENAME"
445 :include-path '( "/include" "../include" "/c/include" )
446 :system-include-path '( "/usr/include/c++/3.2.2/" )
447 :spp-table '( ("MOOSE" . "")
448 ("CONST" . "const") ) )
451 In this case each item in the include path list is searched. If the
452 directory starts with "/", then that expands to the project root
453 directory. If a directory does not start with "/", then it is
454 relative to the default-directory of the current buffer when the file
457 The include path only affects C/C++ header files. Use the slot
458 @code{:header-match-regexp} to change it.
460 The @code{:system-include-path} allows you to specify full directory
461 names to include directories where system header files can be found.
462 These will be applied to files in this project only.
464 The @code{:spp-table} provides a list of project specific #define
465 style macros that are unique to this project, passed in to the
466 compiler on the command line, or are in special headers.
467 See the @code{semantic-lex-c-preprocessor-symbol-map} for more
468 on how to format this entry.
470 If there is a single file in your project, you can instead set the
471 @code{:spp-files} to a list of file names relative to the root of your
472 project. Specifying this is like setting the variable
473 @code{semantic-lex-c-preprocessor-symbol-file} in semantic.
475 If you want to override the file-finding tool with your own
476 function you can do this:
479 (ede-cpp-root-project "NAME" :file "FILENAME" :locate-fcn 'MYFCN)
482 Where @var{MYFCN} is a symbol for a function. The locate function can
483 be used in place of @code{ede-expand-filename} so you can quickly
484 customize your custom target to use specialized local routines instead
485 of the default @ede{} routines. The function symbol must take two
490 The name of the file to find.
492 The directory root for this cpp-root project.
496 If the cpp-root project style is right for you, but you want a dynamic
497 loader, instead of hard-coding path name values in your @file{.emacs}, you
498 can do that too, but you will need to write some lisp code.
500 To do that, you need to add an entry to the
501 @code{ede-project-class-files} list, and also provide two functions to
502 teach @ede{} how to load your project pattern
504 It would look like this:
507 (defun MY-FILE-FOR-DIR (&optional dir)
508 "Return a full file name to the project file stored in DIR."
509 <write your code here, or return nil>
512 (defun MY-ROOT-FCN ()
513 "Return the root fcn for `default-directory'"
514 ;; You might be able to use `ede-cpp-root-project-root'
515 ;; and not write this at all.
519 "Load a project of type `cpp-root' for the directory DIR.
520 Return nil if there isn't one."
521 ;; Use your preferred constructin method here.
522 (ede-cpp-root-project "NAME" :file (expand-file-name "FILE" dir)
526 (add-to-list 'ede-project-class-files
527 (ede-project-autoload "cpp-root"
530 :proj-file 'MY-FILE-FOR-DIR
531 :proj-root 'MY-ROOT-FCN
533 :class-sym 'ede-cpp-root)

579 ``locate'' command, or ``GNU Global''.
581 Configuration of the tool you want to use such as @code{locate}, or
582 @code{global} will need to be done without the aid of @ede{}. Once
583 configured, however, @ede{} can use it.

611 bugs in @ede{}. A knowledge of Emacs Lisp, and some @eieio{}(CLOS) is
614 @ede{} uses @eieio{}, the CLOS package for Emacs, to define two object
615 superclasses, specifically the PROJECT and TARGET. All commands in
616 @ede{} are usually meant to address the current project, or current
619 All specific projects in @ede{} derive subclasses of the @ede{}
620 superclasses. In this way, specific behaviors such as how a project
621 is saved, or how a target is compiled can be customized by a project
622 author in detail. @ede{} communicates to these project objects via an
623 API using methods. The commands you use in @ede{} mode are high-level
624 functional wrappers over these methods. @xref{(eieio)Top}. For
625 details on using @eieio{} to extending classes, and writing methods.
627 If you intend to extend @ede{}, it is most likely that a new target type is
628 needed in one of the existing project types. The rest of this chapter
629 will discuss extending the @code{ede-project} class, and it's targets.
630 See @file{project-am.el} for basic details on adding targets to it.
632 For the @code{ede-project} type, the core target class is called
633 @code{ede-proj-target}. Inheriting from this will give you everything
634 you need to start, including adding your sources into the makefile. If
635 you also need additional rules in the makefile, you will want to inherit
636 from @code{ede-proj-target-makefile} instead. You may want to also add
637 new fields to track important information.
639 If you are building currently unsupported code into a program or shared
640 library, it is unlikely you need a new target at all. Instead you
641 would need to create a new compiler or linker object that compiles
642 source code of the desired type. @ref{Compiler and Linker objects}.
644 Once your new class exists, you will want to fill in some basic methods.

710 @item ede-buffer-mine
711 Return non-nil if a buffer belongs to this target. Used during

723 Return the documentation file information about this file would be
725 @item ede-documentation
726 List all documentation a project or target is responsible for.
729 @node Sourcecode objects
730 @section Sourcecode objects
732 @ede{} projects track source file / target associates via source code
733 objects. The definitions for this is in @file{ede-source.el}. A source
734 code object contains methods that know how to identify a file as being
735 of that class, (ie, a C file ends with @file{.c}). Some targets can
736 handle many different types of sources which must all be compiled
737 together. For example, a mixed C and C++ program would have
738 instantiations of both sourcecode types.
740 When a target needs to know if it will accept a source file, it
741 references its list of source code objects. These objects then make
744 Source code objects are stored in the target objects as a list of
745 symbols, where the symbol's value is the object. This enables the
746 project save file mechanism to work.
748 Here is an example for an instantiation of an Emacs Lisp source code object:
751 (defvar ede-source-emacs
752 (ede-sourcecode "ede-emacs-source"
754 :sourcepattern "\\.el$"
755 :garbagepattern '("*.elc"))
756 "Emacs Lisp source code definition.")
759 If you want to recycle parts of an existing sourcecode object, you can
760 clone the original, and then just tweak the parts that are different.
764 (defvar ede-source-emacs-autoload
765 (clone ede-source-emacs "ede-source-emacs-autoload"
766 :name "Emacs Lisp Autoload"
767 :sourcepattern "-loaddefs\\.el")
768 "Emacs Lisp autoload source code.")
771 In this case, the garbage pattern is the same.
775 @node Compiler and Linker objects
776 @section Compiler and Linker objects
778 In order for a target to create a @file{Makefile}, it must know how to
779 compile the sources into the program or desired data file, and
780 possibly link them together.
782 A compiler object instantiation is used to associate a given target
783 with a given source code type. Some targets can handle many types of
784 sources, and thus has many compilers available to it. Some targets
785 may have multiple compilers for a given type of source code.
787 @ede{} will examine the actual source files in a target, cross reference
788 that against the compiler list to come up with the final set of
789 compilers that will be inserted into the Makefile.
791 Compiler instantiations must also insert variables specifying the
792 compiler it plans to use, in addition to creating Automake settings for
793 @file{configure.in} when appropriate.
795 Compiler objects are stored in the target objects as a list of
796 symbols, where the symbols value is the object. This enables the
797 project output mechanism to work more efficiently.
799 Targets will also have a special "compiler" slot which lets a user
800 explicitly choose the compiler they want to use.
802 Here is an example for texinfo:
805 (defvar ede-makeinfo-compiler
807 "ede-makeinfo-compiler"
809 :variables '(("MAKEINFO" . "makeinfo"))
810 :commands '("makeinfo -o $@ $<")
811 :autoconf '(("AC_CHECK_PROG" . "MAKEINFO, makeinfo"))
812 :sourcetype '(ede-makeinfo-source)
814 "Compile texinfo files into info files.")
819 When creating compiler instantiations, it may be useful to @code{clone}
820 an existing compiler variable. Cloning allows you to only modify
821 parts of the original, while keeping the rest of the same.
822 Modification of the original will result in the clone also being
823 changed for shared value slots.
825 The second important object is the linker class. The linker is similar
826 to the compiler, except several compilers might be used to create some
827 object files, and only one linker is used to link those objects together.
829 See @file{ede-proj-obj.el} for examples of the combination.

1271 The default locate function expands filenames within a project.
1272 If a header file (.h, .hh, etc) name is expanded, and
1273 the @code{:locate-fcn} slot is @code{nil}, then the include path is checked
1274 first, and other directories are ignored. For very large
1275 projects, this optimization can save a lot of time.
1277 Directory names in the path can be relative to the current
1278 buffer's @code{default-directory} (not starting with a /). Directories
1279 that are relative to the project's root should start with a /, such

1298 C Preprocessor macros for your files.
1299 Preprocessor symbols will be used while parsing your files.
1300 These macros might be passed in through the command line compiler, or
1301 are critical symbols derived from header files. Providing header files

1320 Regexp used to identify C/C++ header files.
1324 Type: @code{(or null function)} @*
1325 Default Value: @code{nil}
1327 The locate function can be used in place of
1328 @dfn{ede-expand-filename} so you can quickly customize your custom target
1329 to use specialized local routines instead of the EDE routines.
1330 The function symbol must take two arguments:
1331 NAME - The name of the file to find.
1332 DIR - The directory root for this cpp-root project.
1334 It should return the fully qualified file name passed in from NAME. If that file does not
