The pptable-diff utility is used to calculate the
difference between two pretty-print tables, which both must provided
in abstract syntax, as ATerms. It takes two tables,
one provided via the
-i option (or
and the other via the
--old option. Any rule found
in the old table but not in the new is printed to
--patch switch is specified, the old pretty-print
table is updated by adding pretty-print rules that are in the new table
but not in the old.
--prune switch is specified, the old pretty-print
table is returned, and with all entries not found the new file removed.
The utility parse-pp-table can be used to convert a concrete pretty-print table to its abstract form.
Parse Table Options
Bring old table up to date by adding all new entries from the new table.
Remove obsolete entries by removing from the old table all entries not found in the new table.
Use the table in the file
table as the old
Common Input/Output Options
The input term given by the file name
In the absence of the
-i option, input
will be read from
The output will be written to the file given by the file name
In the absence of the
output will be written to
The output will be written in the binary (BAF) ATerm format.
ATerms in the BAF format require a lot less space than ones in the TAF format, but the Java ATerm library does not currently support baf ATerms. ATerms in the baf format is the preferred format of exchange between Stratego tools.
Common Debugging Options
Display usage information.
Keep intermediate results produced by the internal stages in the
pretty-printing process. This is only useful for debugging. A high
int indicates increased eagerness
for keeping intermediate results.
Default setting is 0, indicating that no intermediates will be kept.
Silent execution. Same as
Set verbosity level to numerical value
higher the number, the more information about pp-aterm's inner workings are
int can be set to either of the
following verbosity levels, given in increasing order of verbosity:
Displays the tool name and version.
