# follow awk's pattern/action structure?
# if so, probably ditch {} and use , between statements, and
# ; at the end of the block
@1/^thing$/ -> assert(@1 == "thing")


# Patterns
# quote from https://linux.die.net/man/1/awk :
# AWK patterns may be one of the following:
#   - BEGIN
#   - END
#   - /regular expression/
#   - relational expression
#   - pattern && pattern
#   - pattern || pattern
#   pattern ? pattern : pattern
#   - (pattern)
#   - ! pattern
#   pattern1, pattern2 (range pattern)
#
# of all of the above, only ternary operator seems iffy to me

# Control statements
# quote from https://linux.die.net/man/1/awk :
# The control statements are as follows:
#   if (condition) statement [ else statement ]
#   while (condition) statement
#   do statement while (condition)
#   for (expr1; expr2; expr3) statement
#   for (var in array) statement
#   break
#   continue
#   delete array[index]
#   delete array
#   -> exit [ expression ]
#   -> { statements }


# /happy/ should be equivalent to @0/happy/
/happy/ -> @1 = ";", @2 = n@2 + 1;


# basic arithmetic
# plus creating columns if index doesnt exist
(n@1 > n@2) -> @3 = 1 + (n@1 + n@2) / 2;

# and/or creating columns like this maybe?
append(n@3 * 2);


# removing columns either as a statement like this
# NOT IMPLEMENTED YET
del @2;

# or function like this?
del(2);

# probably not like this because consistency would dictate this
# passed the value in column 2 to del, not a reference to column 2.
# or maybe i'm the one being an old stubborn man
# del(@2);


# in place modifications is set (maybe set it as default?)
# print @0 at the end of the script automatically
print(@0)
