build: fix CMAKE_MODULE_PATH usage Fixes #1447. `CMAKE_MODULE_PATH` is meant to be a list of directories, and as such, is not the proper way to launch our scripts. Let's use `${PROJECT_SOURCE_DIR}/cmake` instead. Also, let's not outright set `CMAKE_MODULE_PATH`, but instead append our location to the list.

Revamp the build system. This achieves several goals: * Less reliance on scripts so we have better portability to Windows (though we still have a ways to go for proper Windows support). Luajit, luarocks, moonscript, and busted are all installed via CMake now. * Trying to make use of pkg-config to get the correct libraries. The latest libuv is still broken in this regard, but we'll at least be in a position to use it. * Allow the use of Ninja or make. The former runs faster in many environments, and automatically makes use of parallel builds. This also allows for system installed dependencies--though not through the Makefile just yet--and adds support for FreeBSD. This also make us build libuv and luajit as static libraries only, since we're only concerned about having static libraries for our bundled dependencies.

Allow cmake caller to override DEPS_PREFIX - Caller can override bundled dependency location using DEPS_PREFIX - Cache variable DEPS_PREFIX, using .deps/usr by default - Removed unused variables DEPS_BIN_DIR, DEPS_BUILD_DIR, DEPS_DIR DEPS_INSTALL_DIR - Corner case: if the caller tries to override DEPS_PREFIX after a successful cmake configuration, the caller needs to clear the cache because dependency checks are based on the old value

include(CheckCCompilerFlag)
build: give priority to /sw and /opt/local on Mac OS X Unfortunately, we can't force the specific inclusion of a header file. So if anything add /opt/local/include to the include path--such as libintl--then other dependencies might be drawn from /opt/local at compile time, even though we detected them elsewhere at configure time. This, in turn, causes issues with mixed versions, such as the iconv.h header being pulled from /opt/local/include, but linked against the library in /usr/lib--which can be mismatched versions. So, despite CMake's best effort to treat /sw and /opt/local as just another system area, we really need to give them preferential treatment. To do this, we add them to CMAKE_PREFIX_PATH. This fixes an issue discovered while re-enabling iconv in #1370.

Also, if options are passed via CFLAGS, they are automatically passed on to the underlying build. So this should cover all the necessary ground. This fixes #1647.

Use CMAKE_C_FLAGS variable to set compiler flags. If the compiler is some GNU-alike variant, set the compiler flags to use the gnu99 dialect of C and enable all warnings. Non-GNU compilers may have to have their own magic added to set dialect and enable warnings. Closes #179.

Add automatic generation of headers - The 'stripdecls.py' script replaces declarations in all headers by includes to generated headers. `ag '#\s*if(?!ndef NEOVIM_).*((?!#\s*endif).*\n)*#ifdef INCLUDE_GENERATED'` was used for this. - Add and integrate gendeclarations.lua into the build system to generate the required includes. - Add -Wno-unused-function - Made a bunch of old-style definitions ANSI This adds a requirement: all type and structure definitions must be present before INCLUDE_GENERATED_DECLARATIONS-protected include. Warning: mch_expandpath (path.h.generated.h) was moved manually. So far it is the only exception.

link to rt if it provides clock_gettime As noted in #128, if clock_gettime is provided by librt then it does not end up being linked into the static libuv.a binary. This might be considered a bug in libuv but we can address it here. Detect if librt provides the clock_gettime symbol and, if so, append it to the list of libraries linked into nvim. On non-librt systems the behaviour should be as before.

build: install with the correct permissions The install() command will create the parent directories, but it does so with the user's umask. We want to do our best to make sure the correct permissions are being set, without clobbering existing permissions. To do this, this commit introduces an install_helper(), which is similar in signature to the install() command, to help ensure that directories are created ahead of the actual install() command. This will attempt to use 0644 permissions for files and 0755 permissions for directories by default--though they can be overridden. To make this work correctly, without trying to introduce some mechanism with setting the umask, it meant that there's a small portion that makes use of an "internal" version of the file() command. It has been tested on CMake 2.8.11, 2.8.12, and 3.0.2, and works correctly on all versions. This fixes #1201 and #1086.

Remove outdated and unused manuals #2891 `nvim-[lang].1`: The non-english manuals are completely outdated and still written in roff, as opposed to mdoc, which is used for `nvim.1`. Given that, they're nearly useless at the moment, and when/if they are updated, they should probably be rewritten from scratch using `nvim.1` as a reference. `xxd*.1`: xxd hasn't been in the source tree for a long time, so the manual is of little use. `nvimtutor*.1`: The vimtutor script hasn't ever shipped with nvim, and the consensus seems to be that it won't, at least in the form of an executable installed alongside `$(PREFIX)/bin/nvim` (see #2700). In `nvim.1`, the argument to the `.Os` macro was removed. This was done because its only purpose was to signify that nvim and nvimtutor were part of the "Neovim" distribution, i.e., one and the same, which isn't applicable anymore because `nvimtutor.1` is being removed. From the `.Os` documentation in `man mdoc`: Os Operating system version for display in the page footer. This is the mandatory third macro of any mdoc file. Its syntax is as follows: .Os [system [version]] The optional system parameter specifies the relevant operating system or environment. It is suggested to leave it unspecified, in which case mandoc(1) uses its -Ios argument or, if that isn't specified either, sysname and release as returned by uname(3).

build: install with the correct permissions The install() command will create the parent directories, but it does so with the user's umask. We want to do our best to make sure the correct permissions are being set, without clobbering existing permissions. To do this, this commit introduces an install_helper(), which is similar in signature to the install() command, to help ensure that directories are created ahead of the actual install() command. This will attempt to use 0644 permissions for files and 0755 permissions for directories by default--though they can be overridden. To make this work correctly, without trying to introduce some mechanism with setting the umask, it meant that there's a small portion that makes use of an "internal" version of the file() command. It has been tested on CMake 2.8.11, 2.8.12, and 3.0.2, and works correctly on all versions. This fixes #1201 and #1086.

# Go down the tree.
Revamp the build system. This achieves several goals: * Less reliance on scripts so we have better portability to Windows (though we still have a ways to go for proper Windows support). Luajit, luarocks, moonscript, and busted are all installed via CMake now. * Trying to make use of pkg-config to get the correct libraries. The latest libuv is still broken in this regard, but we'll at least be in a position to use it. * Allow the use of Ninja or make. The former runs faster in many environments, and automatically makes use of parallel builds. This also allows for system installed dependencies--though not through the Makefile just yet--and adds support for FreeBSD. This also make us build libuv and luajit as static libraries only, since we're only concerned about having static libraries for our bundled dependencies.

term: use an argument vector for termopen(). Old behaviour: termopen('cmd') would run `&shell &shcf "cmd"`, which caused the functional tests to fail on some systems due to the process not "owning" the terminal. Also, it is inconsistent with jobstart(). Modify termopen() so that &shell is not invoked, but maintain the old behaviour with :terminal. Factor the common code for building the argument vector from jobstart() and modify the functional tests to call termopen() instead of :terminal (fixes #2354). Also: * Add a 'name' option for termopen() so that `:terminal {cmd}` produces a buffer named "term//{cwd}/{cmd}" and termopen() users can customize the name. * Update the documentation. * Add functional tests for `:terminal` sinse its behaviour now differs from termopen(). Add "test/functional/fixtures/shell-test.c" and move "test/functional/job/tty-test.c" there, too. Helped-by: Justin M. Keyes <@justinmk>

test: Replace vroom by lua/busted for functional tests The 'lupa' python package provides a simple way to seamless integrate lua and python code. This commit replaces vroom by a python script that exposes the 'neovim' package to a lua state, and invokes busted to run functional tests. This is a temporary solution that will enable writing functional tests using lua/bused while a lua client library is not available. The reason for dropping vroom is flexibility: Lua/busted has a nice DSL-style syntax while also providing the customization power of a full programming language. Another reason is to use a single framework for unit/functional tests. Two other changes were performed in this commit: - Instead of "gcc-unittest/gcc-ia32", the travis builds for gcc are now identified by "gcc/gcc-32". They will run unit/functional tests for both 64 and 32 bits. - Old integration tests(in src/nvim/testdir) are now ran by the 'oldtest' target
