How to import a list?

Question

I have a file (myWords.txt) which contains one word on each line :

Word 1
Word 2
---
---
Word 3000

With this file, I create a list :

function! MyFunction()
        let start = reltime()
        exe 'e myWords.txt'
        let myList = []
        exe '%s/.*/\=add(myList, submatch(0))/g'
        exe 'bd!'
        echom printf('Duration = %s seconds', reltimestr(reltime(start))) 
endfunction

It takes me 34.1666367 seconds

What can I do to download my list more quickly ? Could you help me, please ?

Answer 1

I have a file (myWords.txt) which contains one word on each line

Then simply

let mylist = readfile('myWords.txt')

Answer 2

Matt's answer is the best way to do this, but here's an alternative. After you load your file into the buffer, you can call getline() which returns the lines you ask for as a List:

let myList = getline(1, '$')

As a side note, I'd also like to point out that none of your uses of exe are necessary. You can write all of these Ex commands directly into your function:

    e myWords.txt
    %s/.*/\=add(myList, submatch(0))/g
    bd!
