* Development
|
||||||
|
This comes with a self-contained redo toolchain to help in working with the
|
||||||
|
flake. It basically deploys any input flake into the =tmp= directory for easier
|
||||||
|
access.
|
||||||
|
|
||||||
|
redo targets under =tmp/= come in three kinds:
|
||||||
|
- =clean= :: will remove all build products under =tmp/=
|
||||||
|
- =<flake>= :: will make sure a store path to =<flake>= exists and puts an
|
||||||
|
indirect root into =tmp/<flake>=.
|
||||||
|
- =<flake>.rw= :: will make sure a store path to =<flake>= exists and will
|
||||||
|
copy its contents to =tmp/.<flake>.rw= and will link to it from
|
||||||
|
=tmp/<flake>.rw=. (Rationale: On Linux, directories cannot denote reliable
|
||||||
|
targets due to their non-trivial relation to modification time.)

-d print extra debug messages (mostly about dependency checks)

-v run .do files with 'set -v'

-x run .do files with 'set -x'

-c clean up all old targets before starting

Note: do is an implementation of redo that does *not* check dependencies.

It will never rebuild a target it has already built, unless you use -c.
