bind: Apply f to the contents of a monad and merge messages

In arendsee/monadR: A Monadic Pipeline System

Description

This function should not be used directly. Rather you should use the infix operators. They all wrap this function.

Usage

bind(
  x,
  f,
  entry_lhs_transform = entry_lhs_transform_default,
  bind_if = function(m) .single_OK(m),
  bind_else = default_bind_else,
  emit = emit_default,
  m_on_bind = function(x, ...) {     x },
  io_combine = default_combine,
  bind_args = function(m) list(.single_value(m, warn = FALSE)),
  parent_ids = function(m) list(.get_ids(m)[.single_id(m)]),
  expect_rhs_function = TRUE,
  envir = parent.frame()
)

Arguments

x	The input, may or may not be a monad report
f	A function of the value contained in x
entry_lhs_transform	f(m,x,...) a transform of the lhs called on entry
bind_if	f(m) bind rhs to lhs if TRUE
bind_else	f(m,f) action to take if bind_if is FALSE
emit	f(i,o) Emit the input or the output
io_combine	f(m,o) weave m and f(m) into final output
bind_args	function to retrieve the arguments
.single_on_bind	f(m) Action to perform on input monad when binding
