Re: Roll back octave package dependencies?

Something more akin to "frozen" Python applications might be more
appropriate for Octave. But that would be a big install, too: We're sort
of doing that for Octave.app (sans the hypothetical user's actual
application code), and once you pull in all Octave's dependencies, it's
a 2-3 GB install.

 what are the biggest pieces of that?  since you mentioned Python, I'm reminded that Octaves' symbolic package has a Python/Sympy bundled package that comes in at under 20MB. I don't know how much they had to throw away to make that bundle-able version, but I'm guessing something like that is what Iam may have had in mind?

    I've attached a full list of the packages included in Octave.app.
    Here are the biggest ones:
    
    [Cellar] $ du -s * | sort -rn
    1198944    rust
    792704    qt-octave-app
    606248    openjdk@11
    599192    gcc
    284624    python
    246816    openblas
    171336    ghostscript
    154808    cmake
    143280    icu4c
    126840    octave-octave-app@5.2.0
    73504    librsvg
    72616    x265
    58064    suite-sparse
    56944    imagemagick
    48696    gettext
    40536    openssl@1.1
    33112    glib
    31344    hdf5
    30504    fftw
    
    Several of these are part of the build toolchain. (Rust? What do we
    even use that for?) For a runtime-only Octave, as long as you were
    willing to give up the ability to build oct-files, I think you could
    strip out rust, gcc, cmake, saving you close to 1 GB. 600 MB more if
    you wanted to give up Java support.
    
    Looks like rust is just a build-time-only dependency of librsvg. I
    should probably be stripping that out of Octave.app in the first
    place.
    
    So maybe there's only about 350 MB of savings to be had by stripping
    out gcc and cmake, since rust shouldn't be included in the first
    place. Dunno if that's worth giving up the ability to build
    oct-files?
    
    Cheers,
