mergeConfig() function

configMerge

Hi, this kind of script can help developer to merge userconfig and default module config.
I use it in my ALL modules !
I make it public in a way to help you

Using:

In main module core, you can put it in start() function

this.config = configMerge({}, this.defaults, this.config)

your default config will be merge with defined user config !
If the defined user config don’t define all config value (minimal config for exemple), this script will merge it to do an entire config
So you can send your config to node_helper.js without fear of having undefined values

Arg Number	Function
Arg 1	Initial objet
Arg 2	Config model
Arg 3	Config to merge

Load the script in MagicMirror

You have to load the script on the main core of your module

getScripts: function () {
  return [
    "configMerge.js"
  ]
},

Why using it ?

Object.assign() function don’t to all job

it don’t merge all thing in depth

-> object in object and array is not merging

Note:

You can also use the Minified code version mergeConfig.min.js

How download it:

In your terminal use the wget command

wget https://raw.githubusercontent.com/bugsounet/configMerge/master/configMerge.js

or for Minified version

wget https://raw.githubusercontent.com/bugsounet/configMerge/master/configMerge.min.js

@Bugsounet I don’t understand

[Bugsounet]

I will code a sample wait

LoOOooL, now this script is not needed
now MM v2.12.0 have solve this issue
but still in v2.11.x

I understand why you say i don't understand

I see this at now, pfff i don’t read ChangeLog lol

[sdetweil]

@Bugsounet also, _loadash lib is previously loaded, and loadash.merge does the deep merge, while Object.Assign does not.

and it only matters for modules with big deep config structures. like GA

[Bugsounet]

it’s new because in v2.11.x, I have to use mergeConfig()

[sdetweil]

@Bugsounet lodash.merge loaded before 2.12.

just saying it’s easy, if u need to do this, without another script

[Bugsounet]

So I do some another test and not worked without configMerge()

Module name : MMM-Freebox (in dev for new version)
in MMM-Freebox.js:

  defaults: {
    updateDelay:  5 * 1000,
    token: "",
    activeOnly: false,
    showIcon: true,
    showButton: true,
    showBandWidth: true,
    showRate: true,
    showClient: true,
    showClientRate: true,
    showClientCnxType: true,
    showFreePlayer: true,
    showMissedCall: true,
    showVPNUsers: true,
    maxMissed: 3,
    showIP: true,
    showPing: true,
    pingAdress: "google.fr",
    textWidth: 250,
    excludeMac: [],
    sortBy: null,
    debug: false,
    verbose: false,
    dev: false,
    debitText: "Débit total utilisé : ",
    player : {
      showPlayerInfo: false,
      // depuis le firmware 4.2.3, problemes d'affichage des logos
      // essayez avec les ips :  "192.168.0.254" (l'ip du freebox server)
      //                         "mafreebox.free.fr" ou le resultat de l'ip de mafreebox.free.fr
      //                         "212.27.38.253" l'ip de mafreebox.free.fr (a voir si cela fonctionne pour vous)
      ServerIP: "212.27.38.253",
      UseEPGDayURL: true,
      EPGDelay: 2* 60 *60 *1000
    }
  },

I try to merge config with MMM-Freebox.js :

  start: function () {
    this.config = Object.assign({}, this.defaults, this.config)

I send config to node_helper.js with:

  notificationReceived: function (notification, payload) {
    switch(notification) {
      case "DOM_OBJECTS_CREATED":
        this.sendSocketNotification("INIT", this.config)
        break
    }
  },

module configuration in config.js:

{
  module: "MMM-Freebox",
  disabled: false,
  header: "INFO Freebox",
  position: "top_center",
  config: {
    token: "xxxx",
    updateDelay:  5 * 1000,
    activeOnly: false,
    sortBy: "type",
    showButton: true,
    debug: true,
    //dev: true,
    //verbose: true,
    showVPNUsers: true,
    textWidth: 250,
    player: {
      showPlayerInfo: true
    }
  }
},

result in node_helper.js:

[2020-08-10 16:53:52.705] [LOG]    {
  updateDelay: 5000,
  token: 'xxxx',
  activeOnly: false,
  showIcon: true,
  showButton: true,
  showBandWidth: true,
  showRate: true,
  showClient: true,
  showClientRate: true,
  showClientCnxType: true,
  showFreePlayer: true,
  showMissedCall: true,
  showVPNUsers: true,
  maxMissed: 3,
  showIP: true,
  showPing: true,
  pingAdress: 'google.fr',
  textWidth: 250,
  excludeMac: [],
  sortBy: 'type',
  debug: true,
  verbose: false,
  dev: false,
  debitText: 'Débit total utilisé : ',
  player: { showPlayerInfo: true }
}

so config is not merged !

now … Let’s try with configMerge() with SAME configuration
just modify :

  start: function () {
    this.config = configMerge({}, this.defaults, this.config)

result in node_helper.js:

[2020-08-10 17:08:14.984] [LOG]    {
  updateDelay: 5000,
  token: 'xxxx',
  activeOnly: false,
  showIcon: true,
  showButton: true,
  showBandWidth: true,
  showRate: true,
  showClient: true,
  showClientRate: true,
  showClientCnxType: true,
  showFreePlayer: true,
  showMissedCall: true,
  showVPNUsers: true,
  maxMissed: 3,
  showIP: true,
  showPing: true,
  pingAdress: 'google.fr',
  textWidth: 250,
  excludeMac: [],
  sortBy: 'type',
  debug: true,
  verbose: false,
  dev: false,
  debitText: 'Débit total utilisé : ',
  player: {
    showPlayerInfo: true,
    ServerIP: '212.27.38.253',
    UseEPGDayURL: true,
    EPGDelay: 7200000
  }
}

You can’t see that player: {} value is now set and merged with default value

@MichMich :

in MM core js/module.js

	/* setConfig(config)
	 * Set the module config and combine it with the module defaults.
	 *
	 * argument config object - Module config.
	 */
	setConfig: function (config) {
		this.config = Object.assign({}, this.defaults, config);
	},

Can I send you a patch with configMerge() script for solve this developer issue (It take head !) ?

[sdetweil]

@Bugsounet open a PR, describe the problem, and your solution

[Bugsounet]

sure, i just open it

[Bugsounet]

Ok, so, after one month

1. No news on this topic (I have mentionned @MichMich but …)
2. I have open an issue, no news
3. i have make a PR, euh no news too ??

So i decide I close Issue and PR
it’s not a problem for me… i use my own tools

In this forum,
There are not many developers left …
So avoid listening to them, you would have even less
I don’t know what you are looking for

For the moment, you have one motivated!
This is not likely to continue for long …

@bugsounet for @MichMich
