* Instead of having a fixed sleep duration, start a thread
that monitors the subprocess.
* Started thread is joined, if process finishes thread returns
before timeout.
* Should increase speed and reduce overhead on CPU.
* Refactor Command class for easier reading.
* Some other minor clean ups & method renames.
* Change travis to use `env` and `matrix` to select builds.
* Use case instead of ifs to select behaviour.
* Buffer updates now managed by __main__ loop with buf_q.
* Synchronous neovim install temporarily provided by python installer.
* Known issues:
* No ctrl-c/interrupt support on nvim.
* Graphical bug: https://github.com/neovim/python-client/issues/103
Checking for the existence of `jobwait()` function seems like a more
robust way to check if the current Neovim process meets the requirement
of the parallel installer. This condition precludes a very old version
of Neovim built even before the initial Job API was implemented.
The older documentation of vim-plug suggested that the second string
parameter to Plug command was for both branches and tags. But we've
realized that tags and branches are not interchangeable (#174), and it
is now recommended that the user explicitly specify whether it's a
branch or a tag. The now-undocumented second parameter is currently for
branches, but I'd like to change it for tags, as the use of tags are
much more common.
* Main differences from ruby are inside Command class, notably it
poll/sleeps on the subprocess to check output & timeout.
* Another difference, interrupt is not instaneous due to checking var.
* Otherwise, I mainly just mirrored code into objects.
* Note that due to GVim freeze, disabling use on Windows
This makes it easier and faster to kill spawned git processes.
Repetitive `pgrep` command for collecting PIDs is no longer required.
Unfortunately, :pgroup option is not supported on Ruby 1.8 so we can't
remove the old implementation of `killall`.
