I'm not super keen on introducing a new [stack] config section. But I don't have any better ideas for where this should go. [ui] is my best idea, but I thought we decided we wanted to stop stuffing random stuff into [ui]. So I dunno.

mercurial/stack.py
38–39

As I review just this patch, I question if we shouldn't just concatenate and not ::merge() to the revset string. But I know other changes are coming. I assume the final state justifies the extra complexity.

Reading through the remainder of the series, I like the customization of stack evaluation. But the use of config options seems weird to me. It isn't clear why we need config options. It feels like these options should be passed in as function arguments. Now, it will be useful to test these variations. Maybe that does require config options. But until there is a user-facing need for these config options, It feels better to put them in [devel] or something like that.

Is there a future consumer of these config options that justifies them being normal config options?

The goal of this series is to define a clean API so that commands and tools can be built in a stack-definition agnostic way. It's not to define a one-size-fits-all stack definition.

People and companies have different workflows and needs. Their definition of a stack will likely to be different to better match their workflow. I tried finding a way to configure stack as easily as possible. I have the impression that using configuration options is slightly easier than defining a custom extension. I also avoided using directly a revset from the configuration file as I'm not sure it would be the best way to express all situations.

I don't know if the config options best place are in the stack section though.
