Manage notes and tags, with a pluggable back end

Finds the nth index of a char in a string, returns -1 if the char does not exist, or if nth is out of range.

A simple module that provides functions to manipulate, search, and create Arrays, Collections, Lists, and Sets.

The command scans the contents recursively, finds README.md files and builds the index from their first line headings in the root README.md. The generated list with links is inserted into the root README.md. The index start/end marks are defined by the HTML comments like: given $Content='docs', marks are '<!--docs-->'.
