Make notify-on-logging work with newPlot

[nicolaskruchten]

Right now we can't use this function from Python because we only set config during newPlot.

.. and logging

[etpinard]

Currently, the loggers.js module requires the default plot config object:

plotly.js/src/lib/loggers.js

Line 13 in 8f049fd

var dfltConfig = require('../plot_api/plot_config').dfltConfig;

and uses it to determine which log to show in the console and/or the notifier popups.

The default plot config object can be mutated using Plotly.setPlotConfig:

plotly.js/src/plot_api/plot_api.js

Lines 402 to 404 in 8f049fd

	function setPlotConfig(obj) {
	return Lib.extendFlat(dfltConfig, obj);
	}

and this is the only way to get the logging and notifyOnLogging config option to work at the moment.

Routines that depend on the other config options do not rely on the default plot config object; they instead rely on the "graph" config (i.e context) coerced in gd._context during

plotly.js/src/plot_api/plot_api.js

Lines 419 to 524 in 8f049fd

	function setPlotContext(gd, config) {
	if(!gd._context) {
	gd._context = Lib.extendDeep({}, dfltConfig);
	// stash <base> href, used to make robust clipPath URLs
	var base = d3.select('base');
	gd._context._baseUrl = base.size() && base.attr('href') ?
	window.location.href.split('#')[0] :
	'';
	}
	var context = gd._context;
	var i, keys, key;
	if(config) {
	keys = Object.keys(config);
	for(i = 0; i < keys.length; i++) {
	key = keys[i];
	if(key === 'editable' || key === 'edits') continue;
	if(key in context) {
	if(key === 'setBackground' && config[key] === 'opaque') {
	context[key] = opaqueSetBackground;
	} else {
	context[key] = config[key];
	}
	}
	}
	// map plot3dPixelRatio to plotGlPixelRatio for backward compatibility
	if(config.plot3dPixelRatio && !context.plotGlPixelRatio) {
	context.plotGlPixelRatio = context.plot3dPixelRatio;
	}
	// now deal with editable and edits - first editable overrides
	// everything, then edits refines
	var editable = config.editable;
	if(editable !== undefined) {
	// we're not going to *use* context.editable, we're only going to
	// use context.edits... but keep it for the record
	context.editable = editable;
	keys = Object.keys(context.edits);
	for(i = 0; i < keys.length; i++) {
	context.edits[keys[i]] = editable;
	}
	}
	if(config.edits) {
	keys = Object.keys(config.edits);
	for(i = 0; i < keys.length; i++) {
	key = keys[i];
	if(key in context.edits) {
	context.edits[key] = config.edits[key];
	}
	}
	}
	// not part of the user-facing config options
	context._exportedPlot = config._exportedPlot;
	}
	// staticPlot forces a bunch of others:
	if(context.staticPlot) {
	context.editable = false;
	context.edits = {};
	context.autosizable = false;
	context.scrollZoom = false;
	context.doubleClick = false;
	context.showTips = false;
	context.showLink = false;
	context.displayModeBar = false;
	}
	// make sure hover-only devices have mode bar visible
	if(context.displayModeBar === 'hover' && !hasHover) {
	context.displayModeBar = true;
	}
	// default and fallback for setBackground
	if(context.setBackground === 'transparent' || typeof context.setBackground !== 'function') {
	context.setBackground = setBackground;
	}
	// Check if gd has a specified widht/height to begin with
	context._hasZeroHeight = context._hasZeroHeight || gd.clientHeight === 0;
	context._hasZeroWidth = context._hasZeroWidth || gd.clientWidth === 0;
	// fill context._scrollZoom helper to help manage scrollZoom flaglist
	var szIn = context.scrollZoom;
	var szOut = context._scrollZoom = {};
	if(szIn === true) {
	szOut.cartesian = 1;
	szOut.gl3d = 1;
	szOut.geo = 1;
	szOut.mapbox = 1;
	} else if(typeof szIn === 'string') {
	var parts = szIn.split('+');
	for(i = 0; i < parts.length; i++) {
	szOut[parts[i]] = 1;
	}
	} else if(szIn !== false) {
	szOut.gl3d = 1;
	szOut.geo = 1;
	szOut.mapbox = 1;
	}
	}

So, to make the loggers.js know about gd._context, we'll need to pass gd to all Lib.log, Lib.warn and Lib.error calls. For example,

// on https://github.com/plotly/plotly.js/blob/8f049fddbac0ca0382816984b8526857e9714fe6/src/plot_api/plot_api.js#L146
Lib.log('Legacy polar charts are deprecated!');

// would become
Lib.log(gd, 'Legacy polar charts are deprecated!');

Things might get annoying for cases when gd isn't part of the scope in which Lib.(log|warn|error) is called from. Perhaps to make things easier to pass around, we could copy the logging and notifyOnLogging keys in fullLayout.

Note also, that queue module also uses the default plot config object:

plotly.js/src/lib/queue.js

Line 12 in 8f049fd

var dfltConfig = require('../plot_api/plot_config').dfltConfig;

plotly.js/src/lib/queue.js

Lines 91 to 94 in 8f049fd

	if(gd.undoQueue.queue.length > dfltConfig.queueLength) {
	gd.undoQueue.queue.shift();
	gd.undoQueue.index--;
	}

This thing is mostly deprecated, but maybe it would be a good idea to make it work with gd._context as well.

Hmm... it seems we need to pass gd as an argument to these two API functions

plotly.js/src/plot_api/template_api.js

Line 33 in 12303db

exports.makeTemplate = function(figure) {

plotly.js/src/plot_api/template_api.js

Line 287 in 12303db

exports.validateTemplate = function(figureIn, template) {

which may require publishing a major version.

Support for graph div as first argument for Plotly.makeTemplate
and Plotly.validateTemplate is added in #3111 and #3118.
So there shouldn't be a need for v2 🤞
