ini

INI Example

Demonstrates how to add functions for reading and writing INI files.

Note that this is a low-level library that provides the reading and writing functions for the config library.

This example was generated with:

$ bashly init
# ... now edit src/bashly.yml to match the example ...
$ bashly add ini
$ bashly generate
# ... now edit all files in the src folder ...
$ bashly generate

Running the bashly add ini command simply added the src/lib/ini.sh file, which includes functions for reading and writing values from an INI file.

See the files in the src folder for usage examples.
