Function std.uni.unicode.opDispatch

Performs the lookup of set of code points with compile-time correctness checking. This short-cut version combines 3 searches: across blocks, scripts, and common binary properties.

auto opDispatch(string name)() pure @property;

Note that since scripts and blocks overlap the usual trick to disambiguate is used - to get a block use unicode.InBlockName, to search a script use unicode.ScriptName.

See Also

block, script and (not included in this search) hangulSyllableType.

Example

import std.exception : collectException;
auto ascii = unicode.ASCII;
assert(ascii['A']);
assert(ascii['~']);
assert(!ascii['\u00e0']);
// matching is case-insensitive
writeln(ascii); // unicode.ascII
assert(!ascii['à']);
// underscores, '-' and whitespace in names are ignored too
auto latin = unicode.in_latin1_Supplement;
assert(latin['à']);
assert(!latin['$']);
// BTW Latin 1 Supplement is a block, hence "In" prefix
writeln(latin); // unicode("In Latin 1 Supplement")
// run-time look up throws if no such set is found
assert(collectException(unicode("InCyrilliac")));
