The post-edit hook section claimed a `%let` "creates a new variable in the
hook's own scope and is silently discarded" while `call symputx` updates the
existing one. That is not how SAS resolves it: LIBREF and DS already exist in
an enclosing symbol table (mpe_loader's local table), and a macro only gets a
new local when the name is absent from every enclosing table, so both forms
assign to the same variable. Reworded to state that, and to keep the practical
advice (call symputx is explicit and does not depend on the enclosing scope
still holding the name).
Raised in review of #16.
Two pages, both aimed at SAS developers rather than end users:
- Filter in a Pre-Edit Hook: what editors/getdata returns (sasparams.FILTER_TEXT
and the query clauses, never FILTER_RK), when PRE_EDIT_HOOK runs relative to
the filter, and a worked example that widens a date filter to the previous
quarter - re-reading the table so the rows match, and keeping Row Level
Security applied to both branches.
- One Table, Two Rule Sets: moved from the datacontroller.io blog, so the
developer-facing material lives in one place. Images moved to docs/img/.
