SyntaxInformation
gives information used to generate syntax coloring and other advisories when f[…] is entered as input.
Details
- SyntaxInformation [f]={"prop1"->data1,"prop2"->data2,…} defines syntax properties propi for f.
- Possible properties include:
-
"ArgumentsPattern" patterns for the sequence of allowed arguments"LocalVariables" type and allowed positions of local variables"ColorEqualSigns" argument positions for which = should be colored
- The setting for "ArgumentsPattern" is of the form {patt1,patt2,…}, where the patti can be _, __, ___, _., OptionsPattern [], or {p1,…}.
- If the setting for "ArgumentsPattern" specifies that f takes options, then valid option names are determined from Options [f].
- The setting for "LocalVariables" is of the form {"type",{imin,imax}}. Possible types include "Table", "Solve", "Integrate", "Limit", "Plot", "Manipulate". imin and imax give the minimum and maximum argument positions at which the variables can appear. imax can be Infinity .
- A setting for "LocalVariables" of {"type",{imin,imax},"Lexical"} specifies that local variables that appear inside Dynamic should not be specially colored.
- The setting for "ColorEqualSigns" is of the form {imin,imax}.

Specify that f should take exactly two arguments:

Specify that f should have two arguments, followed by options:
Inappropriate options are colored red:
Scope (4)
The first argument of f should be a list of exactly two elements:
The first argument is allowed to be an expression such as a symbol, which could evaluate to a list:
f can have any number of arguments, but each should be a two-element list:
f should allow "Table-like" local iterator specifications at positions 2 through infinity:
f should have one ordinary argument, followed by iterator-type list arguments:
