A primitive file-based dictionary supporting CRUD operations.
This small tool serves as a minimal file-based persistent key-value database supporting CRUD operations with a single lookup key. Assuming infrequent access by a single application, there's no file locking.
Many applications implement this on their own (and usually within a few lines with read and grep); by delegating to this tool, one gets a robust yet small implementation, consistency in usage and storage locations, and the possibility to easily upgrade to the more powerful yet similar miniDB API.
Each database "table" is represented as an individual file (put by default under ~/.local/share/[NAMESPACE/]TABLE; the location can be customized via command-line arguments or $XDG_DATA_HOME). Each record is a line consisting of KEY='VALUE', where VALUE is shell-quoted so that newlines and other special characters can be used. Values can be queried separately; alternatively, single records or the whole database can be gotten and eval'ed into proper shell variables.
