Manual:Scripting

Line joining

Two or more physical lines may be joined into logical lines using backslash character (\). A line ending in a

backslash cannot carry a comment. A backslash does not continue a comment. A backslash does not continue a token

except for string literals. A backslash is illegal elsewhere on a line outside a string literal.

:if ($a = true \

and $b=false) do={ :put “$a $b”; }

:if ($a = true \ # bad comment

and $b=false) do={ :put “$a $b”; }

# comment \

continued – invalid (syntax error)

Whitespace between tokens

Whitespace can be used to separate tokens. Whitespace is necessary between two tokens only if their concatenation

could be interpreted as a different token. Example:

{

:local a true; :local b false;

# whitespace is not required

:put (a&&b);

# whitespace is required

:put (a and b);

}

Whitespace are not allowed

• between '<parameter>='

•• between 'from=' 'to=' 'step=' 'in=' 'do=' 'else='

Example:

#incorrect:

:for i from = 1 to = 2 do = { :put $i }

#correct syntax:

:for i from=1 to=2 do={ :put $i }

:for i from= 1 to= 2 do={ :put $i }

#incorrect

/ip route add gateway = 3.3.3.3

#correct

/ip route add gateway=3.3.3.3

1 2 ... 22 23 24 25 26 27 28 29 30 31 32 ... 188 189
