Prototype

pub fn fmtId(bytes: []const u8) FormatId

Parameters

bytes: []const u8

Example

 test fmtId {
    const expectFmt = std.testing.expectFmt;
    try expectFmt("@\"while\"", "{f}", .{fmtId("while")});
    try expectFmt("@\"while\"", "{f}", .{fmtIdFlags("while", .{ .allow_primitive = true })});
    try expectFmt("@\"while\"", "{f}", .{fmtIdFlags("while", .{ .allow_underscore = true })});
    try expectFmt("@\"while\"", "{f}", .{fmtIdFlags("while", .{ .allow_primitive = true, .allow_underscore = true })});

    try expectFmt("hello", "{f}", .{fmtId("hello")});
    try expectFmt("hello", "{f}", .{fmtIdFlags("hello", .{ .allow_primitive = true })});
    try expectFmt("hello", "{f}", .{fmtIdFlags("hello", .{ .allow_underscore = true })});
    try expectFmt("hello", "{f}", .{fmtIdFlags("hello", .{ .allow_primitive = true, .allow_underscore = true })});

    try expectFmt("@\"type\"", "{f}", .{fmtId("type")});
    try expectFmt("type", "{f}", .{fmtIdFlags("type", .{ .allow_primitive = true })});
    try expectFmt("@\"type\"", "{f}", .{fmtIdFlags("type", .{ .allow_underscore = true })});
    try expectFmt("type", "{f}", .{fmtIdFlags("type", .{ .allow_primitive = true, .allow_underscore = true })});

    try expectFmt("@\"_\"", "{f}", .{fmtId("_")});
    try expectFmt("@\"_\"", "{f}", .{fmtIdFlags("_", .{ .allow_primitive = true })});
    try expectFmt("_", "{f}", .{fmtIdFlags("_", .{ .allow_underscore = true })});
    try expectFmt("_", "{f}", .{fmtIdFlags("_", .{ .allow_primitive = true, .allow_underscore = true })});

    try expectFmt("@\"i123\"", "{f}", .{fmtId("i123")});
    try expectFmt("i123", "{f}", .{fmtIdFlags("i123", .{ .allow_primitive = true })});
    try expectFmt("@\"4four\"", "{f}", .{fmtId("4four")});
    try expectFmt("_underscore", "{f}", .{fmtId("_underscore")});
    try expectFmt("@\"11\\\"23\"", "{f}", .{fmtId("11\"23")});
    try expectFmt("@\"11\\x0f23\"", "{f}", .{fmtId("11\x0F23")});

    // These are technically not currently legal in Zig.
    try expectFmt("@\"\"", "{f}", .{fmtId("")});
    try expectFmt("@\"\\x00\"", "{f}", .{fmtId("\x00")});
}
