John Bauer 7ebfd65a9b Make it so .sm files can contain \-escaped characters. Also, make the 
writer for .dwi files replace control characters with dwi-safe characters.
Other file formats are unaffected.

Steve Checkoway 24a5651f0e Remove all items from a collection equal to a particular element in linear time. Only really useful for Sequences. 2006-11-03 04:46:36 +00:00
Steve Checkoway d571048d2b This is overkill for such a simple operation. Doing it this way should optimize to a single add and it doesn't have any of the problems associated with breaking aliasing rules. 2006-11-01 11:30:41 +00:00
Steve Checkoway cf3a76b600 Doing these conversions through a union is not safe either but more to the point, it isn't what's happening here. 2006-11-01 11:19:52 +00:00
Steve Checkoway e3e5cf77e5 Don't include Foreach.h in RageUtil.h which does not use it. Instead, include it in the individual files that actually use it. 2006-11-01 11:18:46 +00:00
John Bauer 37f9178f61 Add an "Autosync Tempo" feature. This uses a linear Least Squares 
Regression to figure out a line through the user's step errors to minimize
that error.  It then uses the slope of that line to fix the tempo and the
intercept to fix the offset.  Stops are adjusted as if they were originally
calculated as a number of beats, ie the slope is also used to change
the stops.

Also fixed is a bug where the user doesn't get a chance to keep or
reject the sync changes when ESCing (ZZing) from a song.

Glenn Maynard 508aaa2857 remove unused 2006-10-18 20:02:26 +00:00
Glenn Maynard f7f21e2b8c Replace PRNG with a standard MT. 
RandomGen r; r(); now generates [0,2^31-1] on 32-bit platforms,
not [0,2^31-2].  No longer uses MAX_INT, so the default behavior
doesn't depend on the size of an int.

RandomInt no longer generates a float and truncates it.  That
limited the values that could be returned to those that fit in
a 32-bit float.

Remove NR code.  It's not free.

This code is not threadsafe.  Locking access would kill performance.
The old code wasn't, either.  I think most symptoms would be
innocuous enough to not worry about.

Steve Checkoway df9d1f13b1 Allow calculation of a better estimator (still not quite unbiased) for the population standard deviation from a sample. The result will be slightly too low still, but not by very much. 2006-08-19 20:43:43 +00:00

Glenn Maynard f0ba8c3322 "ARRAY_SIZE" is also stomped on by Windows headers. 
Add "ARRAYLEN"; remove ARRAYSIZE after transition.

Steve Checkoway 8c9577ffe9 Unneeded. Vectors are a type of EqualityComparable. 
http://www.sgi.com/tech/stl/EqualityComparable.html
If a particular implementation of the stl isn't c++98 compliant, a global
template<typename T>
bool operator==( const vector<T> &a, const vector<T> &b)
can be written (and operator!= of course).

Steve Checkoway a942c021c7 Cleanup. 2006-07-08 07:07:50 +00:00
Steve Checkoway 80698277cf Don't use rand()%n. The function specified by the ANSI committee is a terrible linear congruential generator. In fact, it's so bad that the low order bit alternates. The algorithm implemented as RandomFloat() seems to be Park and Miller's "minimum standard" generator which is better (but not great). [See Knuth for more information.] 
Any place where you would use rand()%n, use RandomInt(0, n) instead.
