Dietrich Epp 910039b77a Convert files incrementally 
The previous implementation read the entire file into memory and then
processed it. This version uses reasonably-sized buffers and can handle
files of any size.

Since this new conversion code is a bit more complicated, a test suite
has been added which can be run on ordinary Unix systems.

SyncFiles

SyncFiles is a tool for MPW (Macintosh Programmer’s Workshop) which synchronizes files between a Macintosh and Unix system. It is used to copy files between a classic Macintosh development environment (e.g. MPW running on Mac System 7) and a modern Unix environment (e.g. a Basilisk II host system or an AppleShare volume).

What SyncFiles Does

  • By default, only copies files which are newer than the destination file (unless -force is specified). This means that your classic Macintosh’s system should have the clock set correctly!

  • Sets the modification timestamp of the destination file to match the timestamp of the source file.

  • Only synchronizes files which match hard-coded patterns.

  • Converts files to UTF-8 and LF line endings for Unix systems; converts to Mac OS Roman and CR line endings for Macintosh systems.

  • Creates Macintosh files with MPW Shell creator code and text file type.

File Patterns

Copies files named Makefile, and files with the following extensions:

  • C: .c .h

  • C++: .cc .cp .cpp .cxx .hh .hpp .hxx

Usage

Operates in push or pull mode. The tool runs from inside the classic Macintosh environment, so the “push” mode copies from Macintosh to Unix, and the “pull” mode copies from Unix to Macintosh. It is assumed that the Macintosh directory is on a normal disk volume.

Basic Usage

To push files from the current directory,

SyncFiles <DestPath> -push

To pull files from the current directory,

SyncFiles <DestPath> -pull

Other Flags

  • -verbose: Print lots of boring messages.

  • -quiet: Print only errors and warnings.

  • -force: Ignore timestamps, copy all source files to destination.

  • -dry-run: Perform no actions, just print out what would be done.

  • -dir: Specify an alternat Macintosh directory to push from or pull to. By default, pushes from and pulls to the current directory.

  • -delete: Delete files in destination which are missing from source.

Testing

Run sh test.sh to test the text conversion code.
