How to disable electric-indent-mode for a specific file?

Hi,
I would like to disable `electric-indent-mode` for only one file named
`phrases.tex`. Is there a file that I can place in the folder and
tells emacs to disable to it for that file?

Also, is it possible to enable a custom input method, instead of
enabling it manually every time I open the `phrases.tex` file with
`C-u \` The name of the input method I need enabled is `custom-input-
method`. The default input method is `rfc1345`. Is there a way to do
that using that one single file as well?

UPDATE:
I tried adding this to the file with the LaTeX "percent sign comment"
first so `LaTeX` doesn't fail when processing the file to produce a
PDF:

`% -*- electric-indent-mode: nil; current-input-method: "custom-input-
method" -*-`

The electric-indent-mode is applied, but the current-input-method
doesn't seem to be applied. I tried settings both variables `current-
input-method` and `default-input-method` but nothing.

Try using the `eval` keyword:

`% -*- electric-indent-mode: nil; eval: (set-input-method 'custom-
input-method); -*-`

Amazing. It works. Thank you so much!

Glad I could help :)

Also next time instead of doing it manually you can `M-x add-file-
local-variable-prop-line` which greatly simplifies this process.
