if.md

if, unless, ife, unlesse, _if, _unless

The classical "if" (and its "unless" sidekick)

if
  > f.age 3
  set f.designation 'child' # then
  set f.designation 'baby' # else

if (f.age > 3)
  sequence # then
    set f.designation 'child'
  sequence # else
    set f.designation 'baby'
    order_baby_food _

Warning, the direct children are relevant. In the following snip, order_child_seat is considered the "else" part of the if

if (f.age > 3)
  set f.designation 'child'
  order_child_seat _

postfix if and unless

The flor parser will automatically turn

task 'bob' if a > b

into the syntax tree that would result from

if
  a > b
  task 'bob'

else-if

Currently, if an "else if" is needed, it's better to use cond.

improving readability with else and then

"then" and "else" can be aliased to "sequence" and be used within if to make the flow definition easier to read, and especially less confusing.

# at the top of the workflow definition
# alias "then" and "else" to "sequence"

set then sequence
set else sequence

# ...

if (f.age > 3)
  then
    set f.designation 'child'
  else
    set f.designation 'baby'
    order_baby_food _
