getting started with visualisations

Taragorm

Another question - what is the best procedure for visualisation development?

I have a local project (under home) that contains the development package; I can install that using the customURL function.

So far, so good.

After I've changed the package, and re-installed, nothing seems to change, so there must be more to it.

Bluefox

@Taragorm Have you seen that? https://github.com/ioBroker/ioBroker/wiki/How-to-debug-vis-and-to-write-own-widget-set

Taragorm

@Bluefox I have, and I think I followed the instructions, but if I reinstall my adaptor using "from custom URL", nothing much seems to change, even if I restart iobroker.

Clearly I'm doing something wrong?

Bluefox

@Taragorm I do it like this.

My folder structure is like this one:

/opt/iobroker
        iobroker.my-new-adapter
        node_modules
               ...
               iobroker.js-controle
               iobroker.xxxx
               ...

Then I install my new adapter by writing npm i iobroker.my-new-adapter in /opt/iobroker.
As result the npm creates a sym-link to my developer folder:

/opt/iobroker
        iobroker.my-new-adapter
        node_modules
               ...
               iobroker.js-controle
               iobroker.my-new-adapter (symlink)
               iobroker.xxxx
               ...

after that I develop my adapter as usual in /opt/iobroker/iobroker.my-new-adapter even as a git repo.

after every change I write iobroker r vis && iobroker u vis This should work 100%.

Additionally I can write iobroker visdebug my-new-adapter and if I see the output
Disable cache I restart the iobroker (only for the first time).

After that I can directly modify the file /opt/iobroker/iobroker-data/files/vis/widgets/my-new-adapter.html and after every browser refresh it will be loaded anew from disk. So you can fast see your changes.

But, the changes in /opt/iobroker/iobroker-data/files/vis/widgets/my-new-adapter.html must be copied to /opt/iobroker/iobroker.my-new-adapter/widgets/ manually and you may not call iobroker u vis till you do that, else they will be overwritten

Taragorm

Thanks - that's exactly what I needed to know

Taragorm

Hmm.

The module is iobroker.vis-taragorm

iobroker@iobrokerdev /o/iobroker> iobroker visdebug vis-taragorm

/opt/iobroker/node_modules/iobroker.js-controller/lib/setup/setupVisDebug.js:64
            if (!adapterDir) throw 'Adapter not found. Tried: ' + adapterNames2Try.join(', ');
                             ^
Adapter not found. Tried: vis-vis-taragorm, vis-taragorm
iobroker@iobrokerdev /o/iobroker>

however, vis-taragorm.html does exist in widgets, and there is an instance installed ok. I can't see my widget in the list though.

Possiby unrelated, I should also note that I got some errors installing (and many warnings, but I didn't include those):

unix_dgram.target.mk:101: recipe for target 'Release/obj.target/unix_dgram/src/unix_dgram.o' failed

The last message implies this isn't fatal, but I'm new to NodeJS...

The dev env is Debian Stretch

It would be easier, if I can see the repo on github.
Do you have file /opt/iobroker/node_modules/iobroker.vis-taragorm/widgets/taragorm.html ?

Bluefox

BTW, you can deliver in your adapter https://github.com/Taragorm/ioBroker.evohome the widgets too. It is even better.

Taragorm

Thanks for the quick response!

The repo is up at: https://github.com/Taragorm/ioBroker.vis-taragorm

It's mostly template right now.

This is intended for some generic visualisations (and to practice in) so I didn't include it in the evohome repo. I'll add some specific visualisations there once I know what I'm doing.

Taragorm

@Bluefox

iobroker@iobrokerdev ~/projects> ls -l /opt/iobroker/node_modules/iobroker.vis-taragorm/widgets

Seems to be there...

Bluefox

@Taragorm No matter. With iobroker r vis && iobroker u vis it should work.
Not Fast, but work.

Just tried to execute (windows):

and cannot see any errors

Taragorm

Something broken with my install, maybe?

I added a bit of logging to the empty catch block (line 24 here):

    this.enableDebug = function (widgetset) {
        console.log( "widgetset=" + widgetset );

        if (widgetset) {
            // Try to find out the adapter directory out of a list of options
            var adapterDir;
            var adapterNames2Try = ['vis-' + widgetset, widgetset];
            if (adapterNames2Try[0] === adapterNames2Try[1]) adapterNames2Try.splice(1, 1);
            for (var i = 0; i < adapterNames2Try.length; i++) {
                try {
                    var adapterDir2Try = tools.getAdapterDir(adapterNames2Try[i]);
                    // Query the entry
                    var stats = fs.lstatSync(adapterDir2Try);

                    console.log(stats.toString() );

                    // Is it a directory?
                    if (stats.isDirectory()) {
                        //found it!
                        adapterDir = adapterDir2Try;
                        break;
                    }
                } catch (e) {
                    console.error(e);
                }
            }

            if (!adapterDir) throw 'Adapter not found. Tried: ' + adapterNames2Try.join(', ');
        }

and got this:

@Taragorm Can it be, that you have js-controller 1.4.2? Please update to 1.5.7

Taragorm

Certainly looks to be 1.4.2

iobroker@iobrokerdev /o/iobroker> npm outdated
Package                 Current  Wanted  Latest  Location
iobroker.js-controller    1.4.2   1.4.2   1.5.7  iobroker.inst
yargs                     7.1.0   7.1.0  13.2.2  iobroker.inst

main iobroker package calls for "stable", rather than a particular rev - do I just alter the depend there and npm update - or is there a "proper" way to do it?

Bluefox

@Taragorm via npm is ok. Just stop iob before update

Taragorm

Update

Reloaded iobroker from scratch, just to be sure
Updated iob.js-controller to 1.5.7

iobroker@iobrokerdev /o/iobroker> npm list iobroker.js-controller
iobroker.inst@2.0.2 /opt/iobroker
└── iobroker.js-controller@1.5.7

Same error on iob visdebug

Also

Lots of warnings caused by this:

iobroker.inst@2.0.2 /opt/iobroker
└─┬ iobroker.js-controller@1.5.7
  └─┬ winston-syslog@1.2.6
    └── UNMET OPTIONAL DEPENDENCY unix-dgram@~0.2.1

Is there any way to suppress it? I hate clutter in the logfiles!

Also2

I can't see my widget in the vis builder. There's no obvious error in the log tho.

Taragorm

done a bit more digging into the visdebug error, and it seems like the project folder isn't being recognised as a directory:

Trying:/opt/iobroker/iobroker.vis-taragorm

trace code:

                    console.log("Trying:" + process.cwd() + "/" + adapterNames2Try[i]);
                    var adapterDir2Try = tools.getAdapterDir(adapterNames2Try[i]);
                    // Query the entry
                    var stats = fs.lstatSync(adapterDir2Try);
                    console.log("Got stats:" + JSON.stringify(stats) + "  isDir=" + stats.isDirectory());

But it surely is a dir:

it's as if fs is misbehaving?

Bluefox

@Taragorm is the normal iobroker upload vis does not work?

You can force all the steps manually.

Copy your widgets files into /opt/iobroker/node_modules/iobroker.vis/www/widgets directory.
Change /opt/iobroker/node_modules/iobroker.vis/www/js/config.js
Change /opt/iobroker/node_modules/iobroker.vis/www/cache.manifest (just add/change some char to change the hash)
iobroker u vis
To be sure clear the browser cache

Taragorm

fyi, in enableDebug I think:

var stats = fs.lstatSync(adapterDir2Try);

maybe should be
var stats = fs.statSync(adapterDir2Try);

As diagnostics suggest we're finding the link, and lstatSync() returns the link itself, rather than the target of the link.

Changing it, lets things go a bit further, but it still fails somewhat messily:

For now, I'm going to switch my development environment to Windows, as that seems to be working for you.

Bluefox

@Taragorm It is very well, that you want to get the visbebug runnnig, but
I don't understand, why you ignore my other suggestions:

The problem with non existing index.html.original is fixed only on github.
