First steps…
So today we took the first steps, and tried to define some control structures and operators for our language. In the following documentation the symbol # will be used as a magic placeholder. This is what we came up with.
- To give us a greater freedom in the number department of our language, and because we like while-loops, we have decided NOT to include for-loops.
- We will implement a for all-loop in the language with the following syntax:
for all # in #Note that this loop does not iterate through the datastructure in any specific order, and that it will want to have a lot of processes running at the same time, given that they are safe.
- A standard if sentence will be implemented:
if # then # else # - As mentioned before, we like while-loops:
while # - The following choices concerning operators were made:
# + # (add # to #, if # are scalars; concatenate # and #, if # are strings)
# – # (subtract # from #)
# * # (multiply # with #)
# / # (divide # with #)
# := # (# becomes #)
# mod # or # % # (# modulo #, which notation has not yet been chosen)
#^# (empower # by #)
# and # (and operator, for logical expressions)
# or # (or operator, for logical expresseions)
# = # (compare # to #)
# <> # (# is different from #)
|#| (the absolute value of #, if # is a scalar; the lenght of #, if # has one)
That is all for today. I hope I didn’t make too many typos.

Nice.!
We shall soon be ready to EBNF this.
