Add cider-macrostep-expand-all for one-shot full expansion - #3978
Merged
Conversation
`cider-macrostep-expand-all' (bound to `a' in `cider-macrostep-mode') fully expands the form before point in one step via `macroexpand-all', for when you don't want to step down level by level. Unlike the stepwise command it doesn't require the head to be a macro, since a recursive expansion can still reach macros in nested sub-forms. Generalizes the internal expander helper to take the expander name.

A small follow-up to the inline macrostep work:
cider-macrostep-expand-all(bound toaincider-macrostep-mode) fully expands the form before point in one step viamacroexpand-all, for when you don't want to step down level by level to get to the bottom.A couple of details:
edoes), since a recursive expansion can reach macros nested under a non-macro head likedoorlet.Reuses the existing overlay/collapse machinery, so the result is a single collapsible expansion just like a stepwise one. The internal expander helper was generalized to take the expander name.
Also adds documentation for the inline macrostep flow as a whole - the manual only covered the separate-buffer commands until now, so the new section documents
cider-macrostep-expand, the mode's keybindings (includinga), the expandable-head highlighting/navigation and gensym coloring, and the relevant options.
