Can QGIS 3 label engine stack or truncate labels if they don't fit instead of dropping them?

Question

The process in Changing to alternate label if first label does not fit in QGIS? seems to be close to what's needed but given that was 2 years ago, I am wondering if there is a new way of doing this like in the ArcMap label engine?

Stacking - http://desktop.arcgis.com/en/arcmap/10.3/map/working-with-text/stacking-labels-about-stacking-labels.htm

Truncation - http://desktop.arcgis.com/en/arcmap/10.3/map/working-with-text/abbreviating-and-truncating-about.htm

Another option is Key numbering - desktop.arcgis.com/en/arcmap/10.3/map/working-with-text/

To clarify further Strategy 1 - place label as is, Strategy 2 - stack label (break into 2 lines), strategy 3 - truncate, last option -don't show. So that it tries to place the label using 3 strategies before it drops it.

Answer 1

In the documentation, for QGIS 3.x, you can configure Apply label text substitutes :

The Apply label text substitutes option gives you ability to specify a list of texts to substitute to texts in feature labels (e.g., abbreviating street types). Replacement texts are thus used to display labels in the map canvas. Users can also export and import lists of substitutes to make reuse and sharing easier.

In QGIS, check the checkbox (in the layer properties or in the style panel) and click on the ... button on the right for add manually or with a file label text substitutions.
