[PATCH 2/8] add-patch: split out `struct interactive_options`

From
Patrick Steinhardt <ps@pks.im>
Date
Mar 2, 2026, 12:13 UTC
Message-ID
<20260302-pks-history-split-v1-2-444fc987a324@pks.im>
In-Reply-To
<20260302-pks-history-split-v1-0-444fc987a324@pks.im>

The `struct add_p_opt` is reused both by our infra for "git add -p" and "git add -i". Users of `run_add_i()` for example are expected to pass `struct add_p_opt`. This is somewhat confusing and raises the question of which options apply to what part of the stack.

But things are even more confusing than that: while callers are expected to pass in `struct add_p_opt`, these options ultimately get used to initialize a `struct add_i_state` that is used by both subsystems. So we are basically going full circle here.

Refactor the code and split out a new `struct interactive_options` that hosts common options used by both. These options are then applied to a `struct interactive_config` that hosts common configuration.

This refactoring doesn't yet fully detangle the two subsystems from one another, as we still end up calling `init_add_i_state()` in the "git add -p" subsystem. This will be fixed in a subsequent commit.
