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`.
In order to install Gist as a plugin, you have to modify its `dir` to be
the `plugin` subdirectory of the normal path of the plugin if it were an
ordinary pathogen-compatible Vim plugin.
Plug 'https://gist.github.com/952560a43601cd9898f1.git',
\ { 'dir': g:plug_home.'/xxx/plugin', 'rtp': '..' }
PlugClean command was incompatible with the above trick, so it was
updated not to remove the parent directory of `dir` of each plugin.
There's a fairly widespread convention which recommends indicating the default
confirmation option in uppercase. Granted, the number of applicable instances
in vim-plug is currently only two, but perhaps this'll save users with such an
inclination having to hit Enter just to sate their curiosities.
In the recent versions of NeoVim, jobstart() does not return
monotonically increasing numbers, this caused vim-plug to miss updating
the progress of a task when the job ID for the task is already
reassigned to a new task.
