A macro whose format version is above this build's was dropped on open,
so the next save removed it from the file, and the warning said only
that it couldn't be opened. It is now kept as the file held it
(Workbook::macros_unread, shared between snapshots), never read, listed
or run, and written back unchanged by JSON and xlsx saves, numbered
after the readable macros and around visible names of the storage
shape. Kept macros count toward the 1,000-macro limit after the
readable ones; one too large for an xlsx item is left out. The warning
says it is kept and saved back; damaged and over-limit macros keep
their own warning.
check_limits capped the name, description, notes, step count, depth and
input names, and left the shortcut, permissions, output anchor, default
range, column types, command ids, Repeat ranges, If cells and values and
Stop messages bounded only by the item size; the input declaration was
stored unchecked (rows [5, 2], a cell input with cols [2, 5]).
Now each of them has a limit (docs/macros.md lists them), one-line
fields refuse control characters, and a command id is letters, digits,
. and _ (every registered id passes, tested). An If value may be null
(Empty and NotEmpty ignore it); Repeat.max stays the runner's to bound.
An input's least rows and columns can't pass its most, a cell input is
one row and one column with no header and at most one column type, and
no input lists more column types than columns. check_limits takes every
struct apart field by field, so a new field doesn't compile there until
its limit is decided. A macro from a file that breaks a rule is left
out with the usual warning, never changed to fit.
with_names numbered macros 0..N, and stash::set_many refuses to write a
hidden name beside a visible one of the same name, so a visible
_gc_macro_0_0 (from a file, or defined after the file opened, when the
stored names are no longer in the workbook) made every xlsx save of a
workbook with macros fail. The index is GridCraft's choice: macros now
take the free indices from 0 up, skipping every key a visible
workbook-scope name of the storage shape uses (compared as the stash
reads names), in their order. No arithmetic depends on a number from
the file.
A macro could declare an input called Q1, AB12 or Sum1, and a step written
with plain A1 text, as a recorded one is, would then resolve to the input's
range instead of the cell. check_limits refuses such names; the docs say so.
Regression test.
The inputs paragraph described how a run binds inputs and the message it
shows, which the runner adds in a later pull request. It now says what the
declaration is for and that this version stores and checks it.
Opening a workbook accepted a macro whose format version `v` was above MACRO_VERSION. Serde
dropped the fields this build doesn't know, and the next save wrote the reduced macro back
with `v: 2`, so a newer build would read it as a complete version 2 macro.
A version above MACRO_VERSION is now refused by Macro::check_limits, and parse_macro checks
the raw `v` before reading the steps. Such a macro takes the existing per-macro path: it is
left out with the usual single warning (which now names a newer format), and the rest of the
workbook opens. Tests cover JSON and xlsx hidden names, with current and missing versions as
controls.
