I wonder if it is some colored characters or something in the earlier console output... I'm finding that newlines just seem to fail after some point in my series of command executions
from wexpect.
Ok, here's a testcase. It wasn't caused by colored output.
I am running with py -3 testcase_main.py
When you comment out the first line of testcase.py then things work. Unfortunately I can't remove this import in my real-world usage.
You can uncomment the shell.interact()
and get the popup shell, and then press enter and the script will continue.
testcase.py
import readline # pip install pyreadline
# comment out the above import and all will be OK!!!
# unfortunately my real-world use-case is requiring that module, and removing it is out of my control
print("Your text")
print('back to normal now')
input("Run SVN Update?([yes]/no) : (assuming 'yes' in 1s-Press key to change.)")
print('WARNING! There are local changes un-committed:')
print(r' C:\Users\someone\git\test\blah\SOME_thing is missing!')
input('^^^ Press enter to acknowledge the above ^^^')
print('done!')
testcase_main.py
print("Your text")
import time
from wexpect import spawn
from wexpect import TIMEOUT, EOF
unique_prompt = '123123expect123123'
shell = spawn('cmd.exe')
time.sleep(1)
shell.sendline('PROMPT {}'.format(unique_prompt))
shell.expect(unique_prompt)
print('*** got cmd prompt')
shell.sendline('py -3 testcase.py')
DEBUG=False
i=0
always_break = False
while i!=1:
i = shell.expect([TIMEOUT,
unique_prompt,
u'Press ENTER to continue',
u"Run SVN Update\?\(\[yes\]\/no\)\s*: \(assuming 'yes' in 1s",
u'Run SVN Update\?\(\[yes\]\/no\)',
u'User for SVN:',
u'Password:',
u'Username:',
u'\^\^\^ Press enter to acknowledge the above \^\^\^'
], timeout=4)
print('expect gave I is : {}'.format(i))
if i == 2:
shell.sendline('\n')
elif (i == 4 or i==3):
shell.sendline(' yes') #note the leading space is required!!!
# shell.interact() # if you uncomment this line, you can press enter in the popup and it will continue
elif (i == 5 or i == 7):
shell.sendline(USERNAME)
elif i == 6:
shell.logfile_read = None # so we don't print the password during debug
shell.sendline(PASSWORD)
if DEBUG:
shell.logfile_read=log
elif i==8:
numbytes = shell.sendline()
print('numbytes from sendline was: {}'.format(numbytes))
elif i==9:
shell.sendline('\r\n')
print('*** finished expecting')

I'm not much of a Windows API expert, where should I start debugging this?
from wexpect.
I have talked with some other people who work on the tools I am using wexpect to automate, and they said pyreadline
should not be required, so I think I am able to have a function which attempts to delete the installed module/package so it doesn't interfere with wexpect.
I am sure it would be good to figure out how to fix this properly though, as I guess other programs might cause a similar problem.
from wexpect.
I found if you replace the import readline
code in testcase.py
with this:
import sys
import mock
sys.modules['readline'] = mock.Mock()
then you I think you can get around later sub-module imports inside the same process.
from wexpect.
Sorry, for my passive behavior.
I've tried, and I could reproduce your issue.
I've added an interact()
call to see what happening in the console window. (Please add it for following tests)
...
shell = spawn('cmd.exe')
shell.interact() # <<<
time.sleep(1)
...
And, here is the wondow. (Using Python 3.7.5, virtualenv, wexpect<=3.0.0)
BUT
I've upgraded wexpect to 3.1.0
And, here is the wondow:
And the program finished succesfully.
(virt_i13) C:\Users\usr>python testcase_main.py
Your text
*** got cmd prompt
expect gave I is : 1
*** finished expecting
Please upgrade wexpect to 3.1.0, or higher. Note, that wexpect is not a one-file module anymore. You need to install it.
