os.ls() can't open dir

[JasonHonor]

V version:
0.1.10
OS:
CentOS 7.6.1810

What did you do?
using os.ls() to list files of the current directory.

import os

fn main()
{
    //get the type of os
    ostype:=os.user_os()
    println('OsType:$ostype')

    hostname:=os.exec('hostname')
    println('Hostname:$hostname')

    //get home dir of current user
    home:=os.home_dir()
    println('HomeDir:$home')

    //get the current executable file path.
    exepath:=os.getexepath()
    println('ExePath:$exepath')

    pwd:=os.exec('pwd')
    println('CurrentDir:$pwd')

    //execute a command and fetch result string.
    uname:=os.exec('uname -ra')
    println('Uname:$uname')

    println(os.ls(pwd))
}

What did you expect to see?
[user@centos os_info]$ ls
os_info os_info.v

What did you see instead?
[user@centos os_info]$ v run os_info.v |more

Can you run ls /home/user/code/v/examples/os_info in your terminal?

[JasonHonor]

yes, the result as following:

[user@centos os_info]$ ls /home/user/code/v/examples/os_info
os_info  os_info.v

[medvednikov]

And now try

import os
fn main() {
  files := os.ls('/home/user/code/v/examples/os_info')
  println(files)
}

[JasonHonor]

Successfully it run.

[user@centos os_info]$ v run os_try.v
============ running os_try ============
["os_info.v", "os_info", "os_try.v", "os_try"]

[medvednikov]

Ok I think I know what it is:

pwd:=os.exec('pwd')

You need to call .trim_space()

But it's much better to use a function:

pwd:=os.getwd()

[JasonHonor]

ok, thanks.
