UltiSnips

Access buffer variables in Vim interpolation

Asked by Jose Quepuy

Hi, first of all kudos for a great plugin: it's awesome.

I'm a relatively new Vim user by any means. My question is: Is there a way to access the buffer's variables in a Vim interpolation (the buffer in question is the one where the snippet will be expanded in)? I have some buffer variables that I set according to filetype and would like to use them in a UltiSnip snippet using Vim interpolation.

Here is an example of a UltiSnip snippet I'm trying to define:

snippet \todo "TODO comment" b
`!v b:comment_strb` TODO: $1`!v b:comment_stre`$0
endsnippet

I want it to expand to the appropriate comment string defined for the programming language (which I define in the b:comment_strb and b:comment_stre variables in a ftplugin vim file).

Thanks for your help.

Not sure what the question is. This (what you posted) works:

snippet \todo "TODO comment" b
`!v b:comment_strb` TODO: $1`!v b:comment_stre`$0
endsnippet

Have a look at https://github.com/honza/vim-snippets/blob/master/UltiSnips/all.snippets for a more general approach to figuring out how to comment a line.

SirVer,

Thanks for your quick response. It does work now (I may have had a typo or the variable was not set correctly for the buffer I was working with to test the snippet). I'm still learning the plugin and trying to make more advanced snippets.

Thank you for your time.
