[Guidolib-devel] Implementation of tempo indications

Implement tempo indications. They can be of 3 types :

	- Textual only like \tempo<"Allegro"> . It will be displayed as a 
string.

	- BPM like \tempo<"Allegro", "1/4=120">. The string is displayed 
followed
	by a note and the bpm value.

	- Note equivalence like \tempo<"Allegro", "1/4=1/8">.
	The string is displayed followed by a note = another note.

Modified files : ARTempo.h, cpp, GRTempo.h,cpp

Hi Jerome and Stephane,

thanks for implementing this feature, I really missed it already.

We might need also dotted notes for things like 1/4. = 120 or 1/4. = 1/4

Hi Juergen,

Actually dotted note are handled but not with the "." syntax. You can use
3/8 to represent a dotted quarter note for example.

We started with the Basic guido specification that says for tempo tag :

\tempo<s,s2> where s2 of the form "x/y=3Dn", thus i just forgot the "."
syntax. Do you think it it absolutely necessay to support the "." syntax?

ok, I see.

Because it's already possible to specify dotted notes by their duration, 
it would be only some kind of "nice" feature. But it's not absolutely 
necessarily needed.

I guess there are more important things at the moment. We should add a 
remark into the GUIDO spec "dotted notes can be represented by a 
duration without dots....".

Not really: there isn't any ambiguity in case of tempo marking, but on=20=

the score it's different to write c/4. and c*3/8: the former is to be=20
written with a dot while the latter may be written using a tie and=20
therefore the 2 notation forms are not equivalent.
