## Sortdir
|
|
|
|
|
|
|
|
|
|
*Sortdir* is a powerful utility for managing ProDOS directories. It provides
|
|
|
|
|
a number of functions, all of which may be applied to an individual directory,
|
|
|
|
|
a directory tree or an entire volume:
|
|
|
|
|
|
|
|
|
|
- Checking directory integrity and making repairs
|
|
|
|
|
- Multi-level directory sort
|
|
|
|
|
- Manipulating the case of filenames *
|
|
|
|
|
- Manipulating the format of time and date information *
|
|
|
|
|
- Zeroing free blocks
|
|
|
|
|
|
|
|
|
|
*Sortdir* is intended to help users migrate to the new ProDOS 2.5 release,
|
|
|
|
|
which is currently in alpha. The code has been testing with ProDOS 2.5a8,
|
|
|
|
|
but should run on older versions of ProDOS. The features marked with an
|
|
|
|
|
asterix (\*) above allow directory entries to be converted from the legacy
|
|
|
|
|
format to the new ProDOS 2.5 format, and vice versa.
|
|
|
|
|
|
|
|
|
|
ProDOS 2.5 releases may be obtained [here](https://prodos8.com/releases/prodos-25/)
|
|
|
|
|
|
|
|
|
|
### System Requirements
|
|
|
|
|
|
|
|
|
|
*Sortdir* requires an enhanced Apple //e, //c or IIgs with 128KB of memory.
|
|
|
|
|
It should run on all versions of ProDOS, but is intended for use with
|
|
|
|
|
ProDOS 2.5.
|
|
|
|
|
|
|
|
|
|
### Quickstart - Test Disk Image
|
|
|
|
|
|
|
|
|
|
Download the disk image `sortdir.po`. This is a bootable 143KB (Disk \]\[)
|
|
|
|
|
ProDOS 2.5 disk image which includes `SORTDIR.SYSTEM`, ready-to-run.
|
|
|
|
|
|
|
|
|
|
### Build Instructions
|
|
|
|
|
|
|
|
|
|
If you want to build *Sortdir* (and perhaps contribute to the code!), you
|
2020-05-22 23:39:22 +00:00
|
|
|
will require the [`cc65`](https://github.com/cc65/cc65) C cross compiler for
|
|
|
|
|
6502.

|
|
|
|
2020-05-22 23:22:45 +00:00
|
|
|
I also use [Cadius](https://github.com/mach-kernel/cadius) for copying
|
2020-05-22 22:51:26 +00:00
|
|
|
`sortdir.system#ff0000` to an Apple II disk image.
|
|
|
|
|
|
|
|
|
|
On a Linux system, you should be able to build by simply invoking `make`.

### How to Run `SORTDIR.SYSTEM`
|
|
|
|
|
|
|
|
|
|
`SORTDIR.SYSTEM` is a ProDOS system file, which means it loads at address
|
|
|
|
|
$2000. It is possible to launch this program using any application or
|
|
|
|
|
utility that can launch ProDOS systm files, such as Bitsy Bye, which is
|
|
|
|
|
included with ProDOS 2.5.
|
|
|
|
|
|
|
|
|
|
It is also possible to start the program from the ProDOS `BASIC.SYSTEM`
|
|
|
|
|
prompt, using the normal syntax `-/PATH/TO/SORTDIR.SYSTEM`. Since the volume
|
|
|
|
|
name of the disk image provided is `/P8.2.5`, the following command can be
|
|
|
|
|
used to start the program: `-/P8.2.5/SORTDIR.SYSTEM`.
|
|
|
|
|
|
|
|
|
|
When launching `SORTDIR.SYSTEM` from the BASIC prompt it is also possible to
|
|
|
|
|
specify command line parameters. See below for more information. If no
|
|
|
|
|
command line options are provided then *Sortdir* will present an interactive
|
|
|
|
|
user interface.
|
|
|
|
|
|
|
|
|
|
If *Sortdir* is started from a launcher other than `BASIC.SYSTEM`, there is
|
|
|
|
|
no way to pass command line options, so the interactive user interface will
|
|
|
|
|
be used.
|
|
|
|
|
|
|
|
|
|
Because *Sortdir* uses all of the system memory it reboots the system on
|
|
|
|
|
exit. (It is not possible to return to BASIC because the workspace has been
|
|
|
|
|
overwritten.)

This allows the format of the modification time and creation time fields in

ProDOS directories to be converted from the legacy ProDOS format (ProDOS <2.5)
|
|

|
|
to the new date and time formats introduced in ProDOS 2.5. These new formats
|
|
|
|
|
extend the range of dates that may be represented, in a backwards-compatible
|
|
|
|
|
manner. *Sortdir* also allows conversion from the new ProDOS 2.5 date and

|

time format back to the legacy format.
