Perfect syntax check (Flymake) and code-completion if you use [[http://www.cmake.org][CMake]].
cpputils-cmake does all the dirty setup automatically for following plugins and commands,
C-x C-o
in C/C++ file, ff-find-other-file will open correct header file under cursor)Please note cpputils-cmake is independent on those plugins. Only CMake is required.
Tested at Emacs 23.4, 24.3, 24.4
The best way is using Emacs package manager.
** Manual way Download and place cpputils-cmake.el somewhere (say ~/.emacs/lisp), add below code into your .emacs:
(add-to-list 'load-path "~/.emacs.d/lisp/") (require 'cpputils-cmake)
(add-hook 'c-mode-common-hook (lambda () (if (derived-mode-p 'c-mode 'c++-mode) (cppcm-reload-all) ))) ;; OPTIONAL, somebody reported that they can use this package with Fortran (add-hook 'c90-mode-hook (lambda () (cppcm-reload-all))) ;; OPTIONAL, avoid typing full path when starting gdb (global-set-key (kbd "C-c C-g") '(lambda ()(interactive) (gud-gdb (concat "gdb --fullname " (cppcm-get-exe-path-current-buffer))))) ;; OPTIONAL, some users need specify extra flags forwarded to compiler (setq cppcm-extra-preprocss-flags-from-user '("-I/usr/src/linux/include" "-DNDEBUG"))
Quick start:
If your project don't use default path from CMake, check the section "Customize target path" in FAQ for the solution.
mkdir -p hello/src;printf "#include
** flymake [[https://cloud.githubusercontent.com/assets/184553/5368660/cbc0c70c-805c-11e4-8723-a2ae752a549d.png]]
flycheck [[https://cloud.githubusercontent.com/assets/184553/5368798/ca25c044-805e-11e4-9859-805601784519.png]] M-x compile [[https://cloud.githubusercontent.com/assets/184553/5368693/43295ad4-805d-11e4-9125-f21209c8bd88.png]]
You can also M-x cppcm-compile
to compile the current excutable only.
** gdb
Press hotkey C-c C-g
(I suppose you've copied my setup).
gud-gdb starts and the binary "~/your-projects-blah-blah/hello/build/main" is loaded automatically.
** auto-complete You also need install auto-complete-clang. [[https://cloud.githubusercontent.com/assets/184553/5369140/721c9648-8063-11e4-9ab4-75f0e8ea88c8.png]]
company-mode [[https://cloud.githubusercontent.com/assets/184553/5368579/c03fec24-805b-11e4-8fce-b611b2621318.png]] company-c-headers [[https://cloud.githubusercontent.com/assets/184553/5368489/e7b8ecf2-805a-11e4-8b06-818b96fb2049.png]]
** Open header file
Press the hotkey C-x C-o
or M-x ff-find-other-file
. The corresponding header is opened.
(add-hook 'c-mode-common-hook (lambda () (if (derived-mode-p 'c-mode 'c++-mode) (if (not (or (string-match "^/usr/local/include/." buffer-file-name) (string-match "^/usr/src/linux/include/." buffer-file-name))) (cppcm-reload-all)) )))
** Get executable's full path The command "cppcm-get-exe-path-current-buffer" will copy current executable into kill ring AND OS clipboard.
You need install xsel
under Linux to support OS clipboard.
This could be useful if you need access the executable's directory.
You can yank (paste) the full path to eshell or minibuffer and press "M-backspace" to get the directory name.
* Reload cpputils-cmake
You can always M-x cppcm-reload-all
any time in C/C++ files*.
There is also cppcm-reload-all-hook
which will be called after cppcm-reload-all
. This give you a chance to tweak or override the setup if and only if you are Emacs Lisp expert. Most users don't need tweak these global variables.
Here is the list of global variables third party plugins use: | variable name | plugin | |-----------------------------------------+---------------------| | ac-clang-flags | auto-complete-clang | | company-clang-arguments | company-mode | | cc-search-directories | ff-find-other-file | | flycheck-clang-include-path | flycheck | | semantic-dependency-system-include-path | semantic | | company-c-headers-path-system | company-c-headers |
** Compile only current target "M-x cppcm-compile".
Please press "C-h v cppcm-compile-list" for other compile options.
** Make clean && make "M-x cppcm-recompile"
** Customize target path For example, if the CMakeLists.txt contains something like this:
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${PROJECT_BINARY_DIR}/lib) set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${PROJECT_BINARY_DIR}/lib) set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${PROJECT_BINARY_DIR}/bin)
cpputils-cmake cannot find the target (executable or library).
It will then call the variable cppcm-get-executable-full-path-callback which could be a function object.
Here is a sample:
(setq cppcm-get-executable-full-path-callback (lambda (path type tgt-name) ;; path is the supposed-to-be target's full path ;; type is either add_executabe or add_library ;; tgt-name is the target to built. The target's file extension is stripped (message "cppcm-get-executable-full-path-callback called => %s %s %s" path type tgt-name) (let* ((dir (file-name-directory path)) (file (file-name-nondirectory path))) (cond ((string= type "add_executable") (setq path (concat dir "bin/" file))) ;; for add_library (t (setq path (concat dir "lib/" file))) )) ;; return the new path (message "cppcm-get-executable-full-path-callback called => path=%s" path) path))
You can insert above code into ~/.emacs!
** Macro and included cmake file cpputils-cmake assumes that CMakeLists.txt contains a rule to create executable.
The rule is either "add_executable" or "add_library".
Included file and macro in CMakeLists.txt will be ignored.
A sample CMakeLists.txt we can handle:
project(proj1) set(VAR2 "a2") set(VAR1 a1-${VAR2}) set(TGT hello-${PROJECT_NAME}-${VAR1}") add_executable(${TGT} ${SOURCES})
The executable's name will be "hello-proj1-a1-a2".
** Stop creating Makefiles for flymake Insert below code into ~/.emacs:
(setq cppcm-write-flymake-makefile nil)
Here is the steps to send bug report:
M-x eval-expression
M-x cppcm-reload-all
and send me the output in Message bufferC-h v cppcm-hash
and send me the outputM-x cppcm-version
and send the outputBesides, I still need general environment information like Emacs version and OS version.
