I'm using the exec node to call a perl script that uses the DateTime module. I installed it and all its dependencies using cpan and the script works on the command line, but when I run it from the exec node in node-red, it complains that it can't find the module. I suppose I could set -I in the co…

Just to follow up. Your response inspired the following tests (after saving my sorted user environment in a file on the command line): [{"id":"81ea3e84.bb722","type":"exec","z":"8b5ff0a3.decbe8","command":"env | sort | diff /home/pi/tmp.env - && exit 0","addpay":false,"append":"","useSpawn":"false…

Out of curiosity, what is this perl script doing?

It is parsing a tvpi file from titantv.com , building a json object that the cronplus node takes as input, and makes an adjustment from GMT to EST time zones. I'm going to use it to schedule HDHomeRun recordings by clicking the record buttons on titantv listings. It works if I call the script with p…

[image] hepcat72: It is parsing a tvpi file from titantv.com , building a json object doesnt sound impossible to achieve in native node-red without having to spawn perl scripts? Is it a very complex process?

Perl is my native tongue. It would have taken me much longer to do it natively in node red. I had posted earlier to ask if anyone knew of a way to do datetime math / time zone conversion in node red, but I was too impatient to wait for a response, so I just did it in perl. I'll post about it when…

Am I right in thinking the tvpi file is just XML? I found this on a forum... <tv-program-info version="1.0"> <program> <station>KCRA-DT</station> <tv-mode>digital_cable</tv-mode> <program-title>KCRA 3 News at 6:30pm</program-title> <start-date>20200513</start-date> <start-time>01:30</start-time> <e…

A few things... The times in all tvpi files are GMT, so in order to make it work in my timezone, the times must be converted. (This might be possible in cronplus, but I'm having a hard time following the documentation.) The structure of that JSON is not compatible with where I need it to go. Her…

[image] hepcat72: While it's a simple matter the straight-convert XML to JSON, and I could have easily done that with node red, as you demonstrate, probably with not much more time investment than you, the time input for me would balloon to figure out all the details of everything else But yo…

If I knew as much about me and what my time constraints and knowledge and past efforts in node red were as you do, I might be tempted to think the same thing you do about me. But I try not to make assumptions like that about people. You're assuming I'm not willing to dive in and learn about node r…

Hi, not sure how I've offended you, it wasn't intended, i only tried to encourage a native solution. I thought that was obvious (but I guess not). I don't think I called your character into question? However, I cannot ignore the fact you are clearly are put out, so i apologise. As you said, I don't know you & you don't know me, but rest assured, I wouldn't do that internationally. I meant no offence.
