           Summary: std.string.translate precondition asserts
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: minor
          Priority: P2
         Component: Phobos
        AssignedTo: nobody puremagic.com
        ReportedBy: bearophile_hugs eml.cc



std.string.translate precondition contains code like this:


C[] translate(C = immutable char)(in char[] str, in char[] transTable, in
char[] toRemove = null)  trusted nothrow
    if(is(Unqual!C == char))
in
{
    assert(transTable.length == 256);
    foreach(char c; str)
        assert(c <= 256);
    foreach(char c; transTable)
        assert(c <= 256);
    foreach(char c; toRemove)
        assert(c <= 256);
}



I think those asserts should be:

assert(c < 256);

Why are those asserts in there anyway? A char can't be larger than 255..?

Ah, right. My brain was switched too much off.

This looks better:

    foreach (dchar c; str)
        assert(c < 256);


But this is a full-range translate(), so it should work in the whole range of
[0, 256[, so I this precondition:

in
{
    assert(transTable.length == 256);
    foreach(char c; str)
        assert(c <= 256);
    foreach(char c; transTable)
        assert(c <= 256);
    foreach(char c; toRemove)
        assert(c <= 256);
}


Should be:

in
{
    assert(transTable.length == 256);
}

Btw, for these trivial things you might want to try making pull requests. We
can always use an extra hand with fixing things.
