History of changes

MIDA 0.4.5

• various cosmetic changes;

• make the executable Cabal-installable.

MIDA 0.4.4

• cosmetic corrections in source code;

• switch to better libraries.

MIDA 0.4.3

• various corrections and cosmetic changes;

• improved printing of syntax trees;

• allow more flexible looping expressions.

MIDA 0.4.2

• introduced simplifications on the level of internal language;

• changed default values of some parameters;

• some characters have been replaced with pretty Unicode symbols;

• improved manual.

MIDA 0.4.1

• dramatically improved efficiency, now very long compositions can be quickly rendered;

• lexer: changed style of comments, shell-like comments adopted;

• changed alias of notes: dièse is written now as s not as #, so middle octave is: c5, cs5, d5, ds5, e5, etc.;

• now there are alias for all supported (in MIDI) pitches from 0 to 127, that is: from c0 to g10 (alias c10 -- g10 added);

• changed alias of modulation signs, reason for such change is purely technical -- all alias now are predefined definitions, rather than syntactic sugar, so all alias must be valid identifiers;

• identifiers can contain underline sign (_);

• arbitrary number of files can be specified for loading (from command line, as well as from interactive REPL);

• many purely technical changes that are difficult to explain concisely, but they should be mentioned, most important being addition of test suite and ability to generate source files from syntax trees;

• added command line options: --license and --version.

MIDA 0.4.0

• fixed bug in batch mode;

• added tab completion based on contents of current input line, including completion of file names for some commands;

• detection and rejection of recursive definitions;

• improved interface;

• wholly refactored (and sometimes rewritten) code (it's finally sufficiently elegant);

• more intuitive logic of evaluation in some corner cases;

• optional displaying of simplified principles (for debug and educational purposes);

• ability to set tempo and program for preview;

• improved documentation.

MIDA 0.3.0

• improved interface and parsing;

• added :prv and :load special commands;

• added additional parameters: modulation, breath, aftertouch, and pitch bend;

• fixed minor bugs.

MIDA 0.2.0

• better command line experience: history, auto-completion and more;

• fixed bug with infinite translation of scores that consist of elements which have zero duration;

• introduced conception of sections;

• all operations have become fully polymorphic.

MIDA 0.1.0
