Re: [Dorset] funny in python software
I've never used Kate (vim for me), but it sounds as if it is syntax-highlighting 'connect' in one file and not the other. That suggests either something else has changed so that 'connect' doesn't make sense, or there may be some non-visual problem with 'connect' (eg, an 8bit char in there or - silly examples - you've put "Connect" or "c0nnect" or something like that). Do you know / can you find out what blue highlighting means? Or - shudder - can you open the file in (g)vim and see if it looks OK there? -- Linux Tips: https://www.tiger-computing.co.uk/category/techtips/ -- Next meeting: Online, Jitsi, Tuesday, 2020-12-01 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk

You're saying syslog has an entry complaining about the client.connect? line? What's the entry say? The normal reasons for the error would be failing to make a TCP connection, e.g. the IP address is wrong. -- Cheers, Ralph. -- Next meeting: Online, Jitsi, Tuesday, 2020-12-01 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
Re: [Dorset] funny in python software
Forget this. The 'good' file was named subscriber.py.2 and therefore kate did
not pick it up as a python file. A lot of other things were not coloured as
well.
But I still have a problem in syslog about why it failed on that line and it
never used to.

When I look at the file in kate, there is a difference that I cannot explain.
In these following lines, the word 'connect' is in blue in the failing version,
but not highlighted in the good version. Here are the first few lines:

# Connect to broker
client.connect(broker_address,1883,60) # bad connect word.
# Subscriber to topic
client.subscribe("rc-car-pwm")
I even copied the line out of the good file and pasted into the faulty one, but
'connect' turned blue.
Any thoughts?
