Two new command line programs in ~/tools: scmp and tokens.
1) scmp: will need a bit more fleshing out to be super useful, but here
is what you can do right now:
// This means run the given command line first with the options
// given to p1 and then without, and show the diff in output.
% tools/scmp --p1 '-no-specialization -nowarn' scalac -Ydebug
src/library/scala/Function1.scala
Upcoming features will involve seeing diffs of such things as the
pickled signatures of generated files and the javap disassembly.
2) tokens: tokenizes all the scala files found under any given paths and
prints one token per line.
Example: the five most frequently used tokens under scala/util.
% tools/tokens src/library/scala/util |sort | uniq -c | sort -r | head
-5 598 ')' 598 '(' 347 ; 294 '=' 278 ,
Good to see those parens are balanced.
Example: number of appearances of an identifier called x:
% tools/tokens src/library/scala/util | grep ^x$ | wc 137
Way to go, x. Review by community.
