when using “pyfile s:pyscript” it seems vim doesn't interpret “s:pyscript” as a variable

问题

A vim-script file calls a python script through:

let s:pyscript = resolve(expand('<sfile>:p:h:h')) . '/pyscript/deploy.py'

echom "sourcing " . s:pyscript
pyfile s:pyscript

the echom-command shows me the expansion points to the correct file, but the following pyfile s:pyscript results in an error:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
IOError: [Errno 2] file or directory not found: '&s:pyscript' 

Which let's me conclude, that everythin after pyfile is immediately considered "python" and vim doesn't evaluate the s:pyscript variable.

What's the way around it? Either in the python-script or the vim-"master" script is fine.

回答1:

Use :execute:

execute 'pyfile ' . s:pyscript
