Here is the postscript indenter / pretty printer which i alluded to yesterday.
It was written by Josh Siegel, not me. It's a *really* nifty program.
Note: you need lex to make it.
p.s. sorry for the gimpy shar format, but it's the only one i could dig up
at the moment. cd to parent directory you want the source in then do
mkdir pspp, then ....

XControlable things:
X 1) Backslashing inner strings (\(\)) bs
X 2) rearrange function definitions ra (not implemented)
X Turn:
X /foo { % bar
X Into:
X /foo % bar
X {
X 3) newline before
X "def" db
X "begin" bb
X "classbegin" cbb
X "dictbegin" dbb
X "end" eb
X "classend" ceb
X "dictend" deb
X "grestore" grb
X "gsave" gsb
X "if" ib
X "{" lcb
X "}" rcb
X "[" lbb
X "]" rbb
X 4) newline after
X "def" da
X "begin" ba
X "classbegin" cba
X "dictbegin" dba
X "end" ea
X "classend" cea
X "dictend" dea
X "grestore" gra
X "gsave" gsa
X "if" ia
X "[" lba
X "]" rba
X "{" lca
X "}" rca
X
XDefault flags:
X ba bb bs cba cbb cea ceb da dba dbb dea deb ea eb lca rcb pn ia gi
X
XWays to change flags:
X
X Put a command line into your PostScript code...
X
X example:
X <beginning of line>%%= -bs +cea -dba
X
X Put a command line into a .pspp in your home directory
X
X example:
X -lba -rba -lca
X
X Set options when you call program...
X
X example:
X pspp -rca
X
XTo run:
X
X% pspp [options files] < file.in > file.out
X
XOr, run it from vi...
X
X:%!pspp
X
XOr,
X
X% pspp -lba foo.cps +lba foobar.ps
X
XSpecial NeWS related features...
X
X lines beginning with cdef are assumed to be cdef calls under NeWS.
X This causes the rest of the file (till the next cdef) to be indented one.
X
X Lines beginning with "#" or "%" are passed through unmodified.
X
XNote to hackers:
X You may notice how I stuck lots of the keywords together into
X a single lex rule... I am not going to explain this... there is
X a reason for this... don't worry about it for now. The reason
X doesn't show up in this version.

At one time I had a Pretty Printer that took in C (or anything else that you wrote a lexer for.) The package also Bolded key words and italiced vars. and in general was a realy nice package. You could write anysort of frontend for it and it came with a bunch. Does anyone know what this package was or where I can get it?
