8.8.1 ptop program

ptop is a source beautier written by Peter Grogono based on the ancient pretty-printer by Ledgard, Hueras, and Singer, modernized by the Free Pascal team (objects, streams, congurability etc)

This congurability, and the thorough bottom-up design are the advantages of this program over the diverse TurboPascal sourcebeautiers on e.g. SIMTEL.

The program is quite simple to operate:

ptop "[-v] [-i indent] [-b bufsize ][-c optsle] inle outle"

The Inle parameter is the pascal le to be processed, and will be written to outle, overwriting an existing outle if it exists.

Some options modify the behaviour of ptop:

-h

Writes an overview of the possible parameters and commandline syntax.

-c ptop.cfg

Read some conguration data from conguration le instead of using the internal defaults then. A cong le is not required, the program can operate without one. See also -g.

-i ident

Sets the number of indent spaces used for BEGIN END; and other blocks.

-b bufsize

Sets the streaming buersize to bufsize. Default 255, 0 is considered non-valid and ignored.

-v

be verbose. Currently only outputs the number of lines read/written and some error messages.

-g ptop.cfg

Writes a default conguration le to be edited to the le "ptop.cfg"
