How to Write File Name Specific Snippets Using UltiSnips or Otherwise

Question

I have been using the plugin called Ultisnips and it is great.

But I am looking for the following feature.

Suppose I have two files history.tex and geography.tex which I edit regularly.

I want to have snippets for each of them but I want them to be independent of each other. What I mean by this is that if I am working on history.tex, a snippet named samplesnip serves some purpose while when I am working on geography.tex the snippet named samplesnip serves a completely different purpose.

Right now what I have is a file named tex.snippets where all my snippets for tex files go. So I do not have the kind of flexibility that I want.

You want to use UltiSnipsAddFiletypes. As the docs say:

The UltiSnipsAddFiletypes command allows for explicit merging of other snippet filetypes for the current buffer. For example, if you edit a .rst file but also want the Lua snippets to be available you can issue the command >

:UltiSnipsAddFiletypes rst.lua

To automatically set the filetype when you edit a file, add the following to your vimrc:

autocmd BufNewFile,BufRead history.tex UltiSnipsAddFiletypes history.tex

Note that as stated in :help 'filetype', vim natively supports the idea of dotted filetypes, so you could change the filetype to history.tex to do custom filetype plugins, syntax, and more.
