从程序中运行击键

Question

I'm writing a program to automate an e-mail process and would like to know if there's a way to run keystrokes from within the program?

For example say I have this string:

str = "test"

And it gets copied to a file:

File.open('str.txt', 'w') { |s| s.puts(str }

And after that I want to use CNTRL-A ; CNTRL-C on the file and copy the information, is this possible in a Ruby program, without the use of external gems?

Operating system: Windows 7

Answer 1

If you can't install gems but can copy ClipText.exe to your current directory, do so then run this code in Ruby:

File.open('str.txt', 'w') { |s| s.puts(str }
`cliptext.exe from str.txt`

For a more rigorous way of executing commands on Windows see " How to execute Windows CLI commands in Ruby? ".

If sending arbitrary keystrokes to other applications is what you're after you can use the gem https://github.com/erinata/auto_click for it. However, if you can't use gems, what you can do instead is run NirCmd (or one of its alternatives ) with the appropriate command line arguments to achieve the same result.

For example:

# Tell the OS to bring up the Notepad window and give it the time
# to do so.
`nircmd win activate ititle notepad`
sleep 0.5
# Select all text in the Notepad window and copy it to the
# clipboard.
`nircmd sendkeypress ctrl+a`
`nircmd sendkeypress ctrl+c`
