# A metamorphic IC test drives a *sequence of edits across several modules*
# through `nim ic` in a fixed build directory (same absolute paths throughout,
# which is what keeps the cache content-stable) and asserts the invariants the
# incremental backend is supposed to guarantee — see doc/ic_ideas.md:
#
# * clean build == incremental build (a fresh in-place rebuild of the
# final sources is byte-identical to
# the binary and full cache set the
# incremental edits converged to)
# * a no-op edit changes no artifact (`noop`)
# * a body-only edit touches no interface (`body-edit`: no `*.iface.bif`
# cookie changes -> no importer re-sem)
# * an interface edit propagates to (`iface-edit`: an `*.iface.bif`
# importers cookie changes and >= 2 modules'
# `*.s.bif` codegen is rebuilt)
#
# File format (a `tests/ic/t*.nim` whose body, after the spec header, contains a
# line `#? metamorphic`):
#
# #? metamorphic
# #!FILE a.nim
# proc greet*(): string = "hi"
# #!FILE main.nim # `main.nim` is always the build root
# import a
# echo greet()
# #!STEP expect: hi
# #!FILE a.nim # re-emit a module to "edit" it
# proc greet*(): string = "hi" # identical content
# #!STEP expect: hi; noop
#
# `#!FILE <name>` blocks (re)write a module in the virtual file system; the
# accumulated file set is materialised before each `#!STEP`. A `#!STEP`'s
# attributes are `;`-separated, each either `key: value` or a bare flag:
# expect: <stdout> noop body-edit iface-edit modules: <n> clean
# The last step always also runs the clean==incremental check.
