Controlled_IO

Files that are open while they exist and closed when they don’t

This is a draft response to a request for a library for Scope-based files. Both binary and text I/O is supported. Please comment on whether or not you find this useful.

The library is completely portable. It has been compiled and tested with GNAT and ObjectAda, on Linux and Windows.

Controlled_Test and Controlled_Text are test programs. Both are user-unfriendly file-copy programs. Controlled_Test performs a binary copy; the output should always be identical to the input. Controlled_Text performs a line-by-line copy of text files; the output may have different line terminators than the input.

Controlled_UTF is a user-unfriendly program to convert a native text file to a Universal Text File.
