vim - How to manage ultisnips scripts?

Question

Filephp.snippets There are more and more snippet...endsnippet blocks;
It becomes more and more difficult to manage, especially when some code blocks are very large;
Observed Download honza/vim-snippets, and find that there is also one language and one file;

Is there any method or folk remedy to manage it?

Using a strategy similar to how Vim detects |ftplugins|, UltiSnips
iterates over the snippet definition directories looking for files
with names of the following patterns: ft.snippets, ft_*.snippets, or
ft/, where "ft " is the 'filetype' of the current document and "" is
a shell-like wildcard matching any string including the empty string.
The following table shows some typical snippet filenames and their
associated filetype.

snippet filename         filetype ~
ruby.snippets            ruby
perl.snippets            perl
c.snippets               c
c_my.snippets            c
c/a                      c
c/b.snippets             c
all.snippets             *all
all/a.snippets           *all

For example, if you have a bunch of ruby ​​snippets, you can split these snippets into separate files. Then they can be managed through directoriesruby/*[.snippets], 也可以直接用文件管理ruby_*.snippets

Actually, how do you manage code?

Answer 2

Solution: folding (based on the following assumptions)

According to my guess, it is assumed that your inconvenient management refers to the more snippets blocks, the longer the file, and it is not easy to browse

.vimrc settings are as follows

set foldcolumn=1 "设置vim左侧1个宽度用来显示folds闭合状态"
set foldmethod=syntax "folds根据语言来决定如何进行闭合"

Command (in normal mode):

zR "打开所有folds"
zM "关闭所有folds"
zi "在以上两个命令间切换，其实是切换foldenable On/Off"

Comparison before and after folds are closed (via the above command)

Operation: First close all snippets blocks through the zM command (the file becomes very small, each snippets only displays one line), then browse easily to find the snippets you need (move the cursor there), and then use zR Or zi opens all snippets. At this time, you can view the content of this snippet;
Bonus: After you follow the above operations, the cursor should be at the bottom. Use the command zz to move the content to the middle of the screen for easy viewing.

At last, a simple .vimrc is attached for reference (Plugin is managed by Vundle):
