The pp-stratego utility is used to pretty-print Stratego source code to concrete syntax. It has two different modes of operation, depending on whether the input is in abstract syntax (an .rtree file) or concrete syntax (an .str file).
In concrete syntax mode, pp-stratego pretty-prints
a Stratego module in concrete syntax (.str) to
concrete syntax by first parsing it and afterwards pretty printing
it. This is a useful operation for inspecting the meaning of concrete
object syntax fragments. This is the default mode.
In abstract syntax mode, pp-stratego --abstract
pretty-prints a Stratego module in abstract syntax (.rtree)
to Stratego concrete syntax.
Input/Output Options
-a, --abstractInput Stratego module is in abstract syntax.
--annotationsPrint annotations on the abstract syntax tree.
-I dir, -Include dir
Include modules from directory dir.
-p file
Use pretty-print table file instead of
the default builtin.
Common Input/Output Options
-i file
The input term given by the file name file
In the absence of the -i option, input
will be read from stdin.
-o file
The output will be written to the file given by the file name
file
In the absence of the -o option,
output will be written to stdout.
-bThe 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
--about
See --version.
-h, -?, --helpDisplay usage information.
--keep int
Keep intermediate results produced by the internal stages in the
pretty-printing process. This is only useful for debugging. A high
value of int indicates increased eagerness
for keeping intermediate results.
Default setting is 0, indicating that no intermediates will be kept.
-S, --silent
Silent execution. Same as --verbose .
0
--verbose int
Set verbosity level to numerical value int. The
higher the number, the more information about pp-aterm's inner workings are
printed.
Alternatively, int can be set to either of the
following verbosity levels, given in increasing order of verbosity:
emergency, alert, critical,
error, warning, notice,
info, debug, vomit.
--versionDisplays the tool name and version.
