Port Silencio to Common Lisp

[gogins]

I think this would be just the chord space code. See https://github.com/rigetticomputing/magicl and others.

[gogins]

Another motive for doing this would be sharing this code with the Common Music and OpenMusic communities,

[gogins]

To do this I must identify the best linear algebra, or at least matrix arithmetic, package for Common Lisp that has an open source license. From CLiki:

• 3d-matrices - This is a library implementing common matrix operations, mainly intended as the counterpiece to 3d-vectors and thus being aimed at operations in 3D space Open source, QuickLisp
• 3d-vectors - This is a simple library for 3D vectors Not applicable
• april - A subset of APL (A Programming Language) compiling to Common Lisp Open source, ASDF
• cl-blapack - A wrapper around the Fortran BLAS and LAPACK libraries for dense linear algebra Open source, ASDF, not often maintained
• cl-tuples - cl-tuples is a libray for writing optimised vector math No license, not often maintained, not sure if applicable
• clem - A library for representing and performing various operations on matrices Open source, ASDF, may be applicable
• CLLIB - CLLIB is a varied collection of Common lisp tools and routines in CLOCC GPL, no ASDF
• FSVD - FSVD is a Common Lisp implementation of Simon Funk's quasi SVD as described at http://sifter.org/~simon/journal/20061211.html in the context of its application to the netflix prize Open Source, QuickLisp, limited applicability
• GSLL - GNU Scientific Library for Lisp allows you to use the GNU Scientific Library (GSL) from Common Lisp Open source, depends on GSL, ASDF, highly applicable
• l-math - L-MATH is a library for simple linear algebra in geometric applications GPL, not maintained
• Linear-algebra - Linear-algebra is a Common Lisp library of numeric linear algebra routines Open source, not often maintained, may be applicable
• lisp-matrix - A matrix linear algebra library for common lisp building on work by Mark Hoemmen, Evan Monroig, Tamas Papp and Rif Open source, ASDF, not often maintained, may be applicable
• LispLab - The main purpose of Lisplab is to to integrate all kinds of mathematics capabilities into one framework GPL, ASDF, not often maintained, looks applicable
• LLA - [unmaintained, maintainers welcome] “Lisp Linear Algebra”, LLA for short, aims to provide convenient and fast matrix operations by binding to LAPACK
• magicl - Matrix Algebra proGrams In Common Lisp: numerical linear algebra routines with auto-generated bindings to BLAS, LAPACK and Expokit Open source, QuickLisp, maintained, looks highly applicable, but no ECL support
• MatLisp - A BLAS and LAPACK linear algebra library wrapper which makes their features accessible through a set of CLOS classes Open source, QuickLisp (?), requires C libraries, looks applicable
• MGL-MAT - MAT is a linear algebra library for working with multi-dimensional arrays which supports efficient interfacing to foreign and CUDA code Open source, more or less maintained, ASDF, requires C libraries, looks applicable
• NLISP - NLISP is an environment for numerical computation and visualisation like IDL or Matlab GPL, ASDF, not often maintained
• Sheafhom - Sheafhom is a package by Mark McConnell for large sparse linear algebra computations over the integers and other exact number types No license, not maintained, but looks interesting
• spartns - Spartns is a SPARse TeNSor representation library Open source, ASDF, maintained, says moved to GitLab but is not there, may be applicable

[gogins]

Googling for best linear algebra for Common Lisp. Not much there except a plug for Clasp on Reddit.

So far, GSLL looks best but it is GPL.

Spartns is just the tensors themselves, no math routines.

So far, magicl looks best. I will start with that. Oops, no help, needs to build and install expokit using Fortran...

[gogins]

I have installed the CL REPL app for Android, which is based on Embeddable Common Lisp. I think this shows I can add nudruz to the Csound for Android app, or write a new app. Source code is here and the license (unfortunately) is GPL v3. ECL itself is LGPL 2.1+.

[gogins]

So the tasks are roughly:

1. Create a silencio system for Common Lisp.
2. Add linear algebra to silencio.
3. Add RIFS code to silencio (easy).
4. Add music graphs to silencio, really just the framework (easy).
5. Port ChordSpace to silencio (not so easy, needs good unit tests).
6. New hosts:
   1. Don't need a new host for Linux, text editor support is fine.
   2. Add ECL, nudruz, and silencio to csound.node.
   3. New Android host like the Csound for Android app but with ECL, nudruz, and silencio built in, and with only HTML5 support for user interfaces.

[gogins]

Removed inapplicable, non open source, non maintained, and non-ECL libraries:

• 3d-matrices - This is a library implementing common matrix operations, mainly intended as the counterpiece to 3d-vectors and thus being aimed at operations in 3D space Open source, QuickLisp, doesn't replace BLAS or LAPACK
• april - A subset of APL (A Programming Language) compiling to Common Lisp Open source, ASDF, no ECL
• clem - A library for representing and performing various operations on matrices Open source, ASDF, may be applicable
• Linear-algebra - Linear-algebra is a Common Lisp library of numeric linear algebra routines Open source, not often maintained, may be applicable
• lisp-matrix - A matrix linear algebra library for common lisp building on work by Mark Hoemmen, Evan Monroig, Tamas Papp and Rif Open source, ASDF, not often maintained, may be applicable
• MatLisp - A BLAS and LAPACK linear algebra library wrapper which makes their features accessible through a set of CLOS classes Open source, QuickLisp (?), requires C libraries, looks applicable
• MGL-MAT - MAT is a linear algebra library for working with multi-dimensional arrays which supports efficient interfacing to foreign and CUDA code Open source, more or less maintained, ASDF, requires C libraries, looks applicable
• spartns - Spartns is a SPARse TeNSor representation library Open source, ASDF, maintained, says moved to GitLab but is not there, partly pplicable (no math)

[gogins]

The above list, evaluated as to maintenance, ECL support, math support, and pure Lisp implementation. Clearly, I will have to run some of the tests or examples in ECL.

• 3d-matrices - This is a library implementing common matrix operations, mainly intended as the counterpiece to 3d-vectors and thus being aimed at operations in 3D space. Contributors: 2. ECL: ? Math: Up to and including eigenvalues. Implementation: Pure Lisp.

• clem - A library for representing and performing various operations on matrices. Contributors: 1. ECL: ? Up to but not including decompositions. Implementation: Pure Lisp.
• Linear-algebra - Linear-algebra is a Common Lisp library of numeric linear algebra routines. Contributors: 0. ECL: ? Math: Same as BLAS. Implementation: Pure Lisp. Works with or is part of Weyl.

[gogins]

Please note weyl. This is a "Common Lisp computer algebra substrate" that looks pretty complete.

[gogins]

Too many ways of doing the same thing on computers!... I could do all this in C++ and compile to WASM to run in HTML5. The killer is redoing all the composing algorithms. Could I get them in C++?

[gogins]

Oh wait, Maxima can be used from Lisp as a library. Note sure yet how this actually works but see http://maxima.sourceforge.net/lisp.html. There is Maxima for Android.

I'm worried this is another Lisp-y "not quite baked yet" story.

[gogins]

Right now there is no Common Lisp for Android or WebAssembly. I am closing this issue until there is.
