I read somewhere on the internet that ~expr was the same as ~~~~expr, which is not, it is a repeated application of the ~ operator, and it happens that applying a boolean negation an odd (and > 1) number of times is useless since it can be rewritten as a single one. Applying ~ twice is ok, it is a cast to bool (~~3 is T), but applying it four or more times is also useless.

Scilint should warn about a number of nested applications of ~ strictly superior to 2.
Scilint should also probably warn about a number of applications of - strictly superior to 1.

Scilint should warn for "," at the end of line.

disp should never be used with several arguments

indexes usually start at 1

⇊Insert a new box after this one.

I found a probably erroneous piece of code:
clear X,Y ;
which is equivalent to:
clear X
Y
and not at all what the programmer probably meant:
clear ('X','Y')

Scilint should warn about this however there is no simple way from the AST.
Three options seem possible to me:

• warn in a more general way about any sequence of two instructions located on the same line, this should detect this one but may be too restrictive
• detect this directly in the parser (probably easier inside my upcoming experimental parser)
• implement some sort of simple textual matching on the source

Among the following examples, only the first one is valid, scilab should warn about the others.
[x, y] = (x, y)
[x, y] = [x, y]
[x, y] = x, y

It would be nice if scilint could export results to the firehose format:
