* monads: Add a template and specialization mechanism for monadic procedures.Ludovic Courtès2017-05-02
| | | | | | | | | | * guix/monads.scm (%templates, %template-instances): New variables. (register-template!, register-template-instance!): New procedures. (template-directory, define-template): New macro. (foldm, sequence, anym): Define using 'define-template'. Avoid replace ellipses with dots. (mapm): Likewise, but do not use 'foldm'. * guix/store.scm: Add 'template-directory' invocation.
* monads: Improve mlet, mlet*, and mbegin documentation.Chris Marusich2017-04-08
| | | | | | | | * doc/guix.texi (The Store Monad) <mlet, mlet*, mbegin>: Clarify their intended usage. * guix/monads.scm (mbegin): Update docstring accordingly. Signed-off-by: Ludovic Courtès <ludo@gnu.org>

| | | | | | | | * guix/monads.scm (mwhen, munless): Rename parameters from 'exp0' and 'exp' to 'mexp0' and 'mexp', respectively. This makes it more obvious that these expressions must be monadic expressions. Signed-off-by: Ludovic Courtès <ludo@gnu.org>
* monads: Fix 'liftN' fallback case.Ludovic Courtès2015-09-04
| | | | | | | | Reported by Andy Wingo <wingo@igalia.com>. * guix/monads.scm (define-lift) <fallback case>: Add missing #'. Remove extra formal parameter. * tests/monads.scm ("lift"): Add test with 'lift1' as a procedure.
