MZ-BER

@sdetweil Thank you Sam! Can you please tell me what the letters in the bracket mean? (e, sdo, sde)

MZ-BER

@mz-ber Oh I guess I understand. If the function is not getting the right details than -> e if everything is okay than -> sdo

sdetweil

@mz-ber exec(“voc list”, (e, sdo, sde)=

execs the command “voc list”
and the exec function returns
error (e)
stdout (sdo)
and stderr(sde)

so if no error (e is null)

it sends the command output to the listResults function

MZ-BER

@sdetweil Thank you for the explanation. Is the function executing voc list in the terminal? If I’m doing manually voc list I’m getting a result.

Is there a way to see what the script is getting back in detail?

Again, thank you very much!

sdetweil

@mz-ber yes executing just like on console

nothing built in to show results.

but you could add a

console.log(sdo)

before the call to listResults()

and see it where u start mm
npm start

it should be the same outout

MZ-BER

@sdetweil Alright, I added the console.log before the call listResult() and it is getting the details from my car. I feel sooo close to get this running but I dont know where it is stuck. :anguished_face:

Is maybe the regex search not getting the details viewed?

listResult: function(output) {
    var re = /^([^ ]+)\s\(([^\)]+)\)\s([^ ]+)$/gm

sdetweil

@mz-ber so the regular expression isn’t finding your text

/^([^ ]+)\s\(([^\)]+)\)\s([^ ]+)$/gm

I use this for building and testing rejects

https://regex101.com/

MZ-BER

@sdetweil Yes, I also checked that with regex101. Can I just parse in the details I have?

listResult: function(output) {
    var re = B-PY 186 (V90) XVASS123345

sdetweil

@mz-ber the regex returns an array of matched things

sdetweil

@mz-ber i think the regex is not expecting the 186

try ths one

/^([^ ]+)\s.*\(([^\/]+)\/([^\)]+)\)$/gm

start of string ^
capture up to the 1st space ([^ ]+)
skip everything to (and including) the open paren \s.*(
get the two things in the parens, separated by /, not including the parens
capture up to the slash ([^/]+)
skip the slash /
capture up to the close pareen ([^)]+)
skip the close paren )
end of string $

MZ-BER

@sdetweil Your one is not working. Here are the details I try to get:

B-PY 186 (V90/2019) YV1PWAKUDK1XXXXXX

I also played a bit with the expression and removed the white space:

before:

listResult: function(output) {
    var re = /^([^ ]+)\s\(([^\)]+)\)\s([^ ]+)$/gm

after:

listResult: function(output) {
    var re = /^([^]+)\s\(([^\)]+)\)\s([^]+)$/gm

That is working based on regex101 and I dont get the error anymore. But nothing is loaded into the MM

sdetweil

@mz-ber the regex has to return 3 items

MZ-BER

@sdetweil Right! And I guess it is doing so? Or am I wrong?

sdetweil

@mz-ber i do not know what the module is expecting or its process

it also does a voc dashboard…
and parses that…

MZ-BER

@sdetweil Yes, I guess voc list should work. But really quick to voc dashboard

That is the list I’m getting

B-PY 186 Position             : (52.55352783203125, 13.4XXXXXXXXXX6, '2022-03-06 20:20:32+01:00', None, None)

B-PY 186 Doors                : Closed
B-PY 186 Windows              : Closed

With the regular expression /^([^\s]+)\s([\w\s]+)\:\s(.+)$/gm it is not perfectly matching the groups:

B-PY 186 should be always in group 1. Do you have an idea to adjust the expression?

MZ-BER

I got it to work! Finally.

The whole problem was my licence plate. The regular expression wasn’t able to grab the right groups. Thank you @sdetweil for helping me to investigate.

sdetweil

@mz-ber how did u fix the regex?

i would change the 1st capture to
in the list

^([^\(]+)\s  =capture up to but not including (

in the scan = capture 1st 8 chars
how long is a license number? always 8?

^(.{8})\s

MZ-BER

@sdetweil said in Volvo on Call:

German Number Plates can have the following format:

ABC-D 123

ABC-DE 12 

AB-C 123 

A-BC 1234

I’m using this regex to get the variations: ^([A-Z]{1,3}-[A-Z]{1,2}\s[0-9]{1,4})\s([\w\s]+)\:\s(.+)$

strawberry 3.141

@mz-ber you are missing some german number plates:

AB-CD 123E electric vehicles

AB-CD 123H oldtimer, but probably not relevant because they do not have the digital information :D

The other exceptions are not relevant for private vehicles.

MZ-BER

@strawberry-3-141 True! Good catch! So I guess every variation can also have an E at the end. Do you know if there is a whitespace between the last digit and the E? If it is without a space, this will work:

^([A-Z]{1,3}-[A-Z]{1,2}\s[0-9,E]{1,5})\s([\w\s]+)\:\s(.+)$
