A few things quickly come into mind: > > * Repository > ** Detect the root directory that conforms a checked-out repository > ** Ignore repository-specific files on other components > ** Interact with repo-management tools? > "magit" detect repo root automatically, you just call "magit-status" in buffer mapped to file/directory inside repo and it show right stuff, may be just create "vc-status" that call "vc-dir" with relevant dir? Anyway why do something about this, "vc-" and "magit-" good enough, is any IDE do better stuff using information about project? > * Project information > ** Name, version, homepage, etc > IMHO, never used this information in any IDE, except name. > * Build system Actually if we talk about C/C++ open source project this is a key for all other features. Almost all C/C++ open source project have makefile/cmake file/scons etc, and thats all. IDE must parse them and exctract information about: - how to compile exactly one source file (to get auto completion, refactoring, right syntax highlight, warning/errors during typing [like flymake] etc) - what executable files was created (to make possible click Debug/Run, to run valgrind with it, excract gcov information etc) And cedet have framework for this, it can parse makefile/cmake, plus you can easily extend it to support new build system, writing something like this: (defclass my-ede-cpp-root-project (ede-cpp-root-project eieio-instance-tracker) ( (custom_build_cmd :initarg :custom_build_cmd :initform "" :type string :custom string :documentation "Set this field to shell command for build your project") (path_to_exe :initarg :path_to_exe :initfrom "" :type string :custom string :documentation "This field hold path to your project") ) "My class for ede projects" :method-invocation-order :depth-first ) So it would be great to finish makefile/cmake support in EDE, plus some easy way to get from EDE information about exact file: includes, defines, plus flags like -std=c++11 -- /Evgeniy
