Observer design pattern in Crystal language
A post where I want to share my thoughts regarding an implementation of an Observer design pattern in Crystal language.
The easiest way to install Neovim on OS X is with
If you need to install it without
brew or your OS is different, refer to an official wiki for instructions.
Run Neovim from the console with
nvim command after installation succeeds.
~/.config/nvim/init.vim configuration file (like
.vimrc for Vim) and
~/.config/nvim/ directory (like
~/.vim/). So, to just start using existed Vim configuration you have to link those files as follows:
At this point you have to try to run Neovim again to be sure that it is compatible with existed configuration. If something fails, you will need to temporary disable it (unload a plugin or comment an option) to prevent any errors.
A full set of differences between Vim and Neovim features you can find here.
If you want support for Python plugins such as YouCompleteMe, you need to install a Python module in addition to Neovim itself.
Installation depends on which version of python you need. But, in general, it is as simple as:
If you need any customization you may refer to the official documentation.
If the problem with existed plugins was an absence of python, it’s a time to re-enable it.
If you prefer using GVim instead of Vim, you would love Neovim-dot-app. It looks almost the same as Graphical Vim, but unfortunately, available only for OS X.
brew is very simple:
If your Vim’s configuration includes inconsistent with Neovim options, to stay backward compatible with Vim, I will suggest to set such options conditionally, for example:
If at this point you still have issues with a configuration (Neovim shows an error at startup or won’t start or some features do not work), unfortunately, you have to read documentation, search a solution on the internet or ask a development team for help.
If you faced with (or solved) such kind of issue, please post a comment below. This might help somebody in future.
After all is set up, you have to try the power of Neovim. The following resources might be useful for further investigation:
