outdent

Removes one level of indentation from an array of single-line strings.

This uniformly outdents the text as much as possible. Whitespace-only lines are always converted to blank lines.

Parameters

Return Value

Type: S[]

Throws

Examples

auto str1 = [
    "    void main()\n",
    "    {\n",
    "        test();\n",
    "    }\n"
];
auto str1Expected = [
    "void main()\n",
    "{\n",
    "    test();\n",
    "}\n"
];
assert(str1.outdent == str1Expected);

auto str2 = [
    "void main()\n",
    "    {\n",
    "            test();\n",
    "    }\n"
];
assert(str2.outdent == str2);
