read csv-data and put it in an array

@Perlchamp said in read csv-data and put it in an array:

i want to code a small app,

there is a minimum set of stuff to do… its not small if you don’t understand the stuff…
I will answer questions and teach a little of the structure… I won’t write anything for you.

Perlchamp

that’s not what i wanted (writing code for me). my big problem is, not to know how i can start, how i can test code-snippets and so on …
i read some articles, but when i want to test some lines of code, i don’t know what to do. in my magicmirror module i can’t do that => error messages … i hope that i have expressed myself clearly and understandably …
if i have a code-snoppet, go to terminal and put in

node xxx.js

path not found, module not found, and many other error messages … maybe i soon despair …

sdetweil

@Perlchamp is the xxx.js in the current folder? if not u need to give path to the file

you can do in MM module, with messages… there are two parts… the server side (node_helper) whose messages (console.log) come out on the same terminal window
the browser side (modulename.js) uses Log.log. and displays only in the developer window

I have modified a logging module that will display them together on the terminal window

https://github.com/sdetweil/MMM-Logging
install this as the FIRST module in the list
use this definition in config.js

		{
            module: 'MMM-Logging',
            disabled: false,
            config: {
                // Module functions out of the box with nothing set here.
                // See below for configurable options.
                echoLocal: true, 
                echoRemote: true,
                overwriteBrowserMethods: true,
                format: "{{message}} ({{folder}}/{{file}}:{{line}} {{method}})",
            }
        },

thanks a lot, i will try to “play” with it. can take some time …

sdetweil

@Perlchamp ok, if you are trying to use the csv-> somethign libraries and installed them in you module folder, then u want to be IN that folder to run your sample node xxx.js tests so the module folder path is right for require()

Perlchamp

@sdetweil said in read csv-data and put it in an array:

u want to be IN that folder

you mean in my module folder? it’s called “MMM-birthdaylist” …

sdetweil

@Perlchamp correct

cd ~/MagicMirror/modules/MMM-birthdaylist
node xxx.js

note xxx.js can’t do anything specifically MagicMirror related no module register no sendSocketNotification

Perlchamp

ok, thanks a lot sam :-)
no i will try to play with it.

Perlchamp

Log.log("hello Log");

=> Log.log(“hello Log”);
^
