Where to put the customized functions for snippet?

I try to create a snippet which needs a little elisp code (about 15 lines). I don't want to put all the code there to make the snippet looks very ugly. A function call is the best choice. But I am not sure where should I put the code for that function.

For example: (Ugly)

${1: $(supper long elisp code here)}

I expect something like:

${1: $(my-function arg)}

Then where should I put my-function code?

Solution

  • You can place the code in your initialization file. The function just needs to be defined before call yas-expand.

    (Edited to include followup from comments.)

    You can also create a .yas-snippet.el file in the same directory as the snippet with your function (example).
