172498620 MDU6SXNzdWUxNzI0OTg2MjA= 981 Split xarray.concat into two functions: xarray.stack and xarray.concat? 1217238 closed 0     2 2016-08-22T16:38:47Z 2019-02-25T17:28:23Z 2019-02-25T17:28:23Z MEMBER      

Currently, xarray.concat can do two different things: - It can concatenate along an existing dimension. - It can stack along a new dimension.

This seemed convenient when I wrote concat, but now seems too automagical.

For example, we need rules to decide which coordinates to expand when stacking (the confusingly named coords and data_vars arguments), but not when concatenating. Currently we use the heuristics in both cases, which leads to undesirable behavior (#899).

Even if we don't split the public API function, we should split it internally.
