Changelog

[unreleased]

[0.3.2]

• #80 bumps the Mafs.cljs and Mafs dependencies to Mafs 0.18.8, fixing #78.

[0.3.1]

• #74 adds resources to the published jar.

[0.3.0]

• #70:

  • Adds

    • emmy.mathbox.physics.{phase-vectors,lagrangian-phase-vectors,hamiltonian-phase-vectors,routhian-phase-vectors} for building out phase portraits like those in the Phase Portrait and Quartic Well examples.

    • many geodesics to the Klein bottle examples.

    • a matrix basis visualization example to examples.mathbox.geom.

  • ode-curve now sets :simplify? to false by default.

  • Converts the phase portrait and quartic well examples to use all server side code and components.

  • emmy.viewer.components.physics/Evolve now adds a :tick entry into its state to force re-renders, since the :state array is mutable.

• #69:

  • Adds emmy.mathbox.physics.{lagrangian-curve,hamiltonian-curve,routhian-curve,geodesic} to the existing ode-curve function.

  • Adds emmy.viewer.physics.{evolve-lagrangian,evolve-hamiltonian,evolve-routhian} to the existing evolve function.

  • Updates the emmy.viewer.components.physics/Evolve component to use a pre-allocated JS output array instead of forcing an allocation on each tick.

[0.2.0]

• #57:

  • Adds emmy.viewer.physics/evolve, for running realtime physics simulations and updating state into a client-side atom.

  • Adds emmy.mathbox.physics/comet, for rendering points with trailing, fading-out history.

  • Updates examples.simulation.{oscillator,ellipsoid,double-ellipsoid} to use the new server-side style.

  • Modifies emmy.viewer/with-let to allow any number of binding pairs, not just one.

  • Adds emmy.clerk/multiviewer for presenting literals via emmy.clerk/multi with their TeX and original representations, both simplified and unsimplified.

  • Adds a missing :offset argument and :z-index, :z-bias and :z-offset to emmy.mathbox.components.plot/Ticks.

  • Adds :start? and end? arguments to to emmy.mathbox.components.plot/LabeledAxis. Also, the :z-index, :z-order and :z-bias arguments are now passed through to Ticks if not supplied directly.

  • Makes the range argument for emmy.mathbox.components.plot/SceneAxes optional.

  • Moves ode-compile from emmy.mathbox.physics to emmy.viewer.physics.

• #56:

  • removes demo.mathbox and demo.mathlive from the published jar, and converts demo.mathbox into an examples-directory-only examples.simulation.utils. The next step is to convert all remaining cljc files into clj files using the new APIs.

  • adds hickory and deep-diff2 as provided dependencies to fix the cljdoc build.

• #55 fixes a bug with live-updating ranges not updating axis labels.

• #53:

  • Consolidates emmy.mafs.{core,coordinate,debug,line,plot} into emmy.mafs. This allows docstrings to appear properly on the ClojureScript side when using emmy.mafs, which all my documentation says to do.

  • Moves the CLJS files for emmy.mathbox.{plot,physics}and emmy.viewer.stopwatch over to emmy.mathbox.components.{plot,physics} and emmy.viewer.components.stopwatch.

  • All reagent-fragment-generating .clj files are now cljc files and included by emmy.viewer.sci. This enables "editor mode" in the latest Clerk builds.

[0.1.0]

• #49:

  • Performs a bunch of README etc updates in preparation for the 0.1.0 release.

  • Bumps portal to 0.42.1 and enables the Leva portal viewers.

  • Removes custom JS compilation from the emmy-viewers/clerk template, which no longer needs it thanks to our precompiled JS.

  • Sets a default camera :up direction of [0 0 1], removing the need to emit in xzy order. This would almost certainly have been ultra confusing to anyone trying to extend the library. Thanks to @ChristopherChudzicki for the suggestion here.

• #44:

  • Adds emmy.viewer.physics and emmy.mathbox.physics in support of the new emmy.mathbox.physics/ode-curve function, similar to parametric-curve but powered by a derivative function and initial state. See the new ode example page for a demo.

  • Adds a new Lorenz attractor example at examples.mathbox.ode.

  • Adds emmy.clerk/{build!,serve!,halt!} to make it more straightforward to configure Clerk with our custom JS bundle.

  • Adds a var-arg viewers argument for other viewers to emmy.clerk/install!.

  • Adds emmy.viewer.stopwatch with a client and server-side stopwatch component; this is currently alpha, but will be used for running physics animations.

  • Migrates examples.simulation.toroid to full server-side style with no more custom viewer.

• #32 updates the emmy-viewers/clerk template to use the new pre-compiled bundle and all of the good stuff in it.

• #40 is a huge PR that adds a full 3D plotting system into emmy-viewers!!

  • Adds emmy.viewer.plot with format-number and label-pi functions, replacing mafs.core/labelPi.

  • Upgrades the examples.manifold.pq-knot to full server-side function style, removing it from the JS bundle.

  • Fixes the :emmy.portal/mafs viewer so that its theming applies in scope; this lets you toggle the theme away by activating :emmy.portal/reagent without affecting the other Mafs scenes in portal.

  • Adds our first set of ClojureScript tests

  • Adds the following functions in emmy.mathbox.plot, backed by components on the ClojureScript side:

    • scene sets up a batteries-included MathBox scene that can host all of the objects and curves described below.

    • point, line and vector provide geometric primitives; point even supports LaTeX labels.

    • parametric-curve, of-x, of-y and of-z support 1d => 1d curves

    • polar-surface, of-xy, of-yz and of-xz support 2d => 1d surface plotting

    • parametric-surface supports full 2d => 3d surface generation

    • vector-field is still in progress, but the basics work. This will eventually expand into the ability to generate vectors along 1d intervals, 2d areas or 3d volumes.

  Huge thanks to Chris Chudzicki of https://www.math3d.org/, who inspired my API here. Steven Petryk and his work on Mafs filled in the gaps for me.

  See these namespaces for examples of the new API in action:

  • https://emmy-viewers.mentat.org/dev/examples/manifold/pq_knot

• #39:

  • moves emmy.mafs.compile to emmy.viewer.compile, for future use by MathBox.

  • ports examples over the new style with emmy.clerk and friends.

• #34 renames emmy-viewers.sci to emmy.viewer.sci.

• #30:

  • Adds emmy.mathbox, with functions for creating Reagent fragments that configure the components from MathBox.cljs for Clerk (no Portal yet!)

  • dev/emmy_viewers/mathbox.clj shows off a basic demo

• #32:

  • Adds emmy.mathlive, with functions for creating Reagent fragments that configure the components from MathLive.cljs for Portal or Clerk

  • dev/emmy_viewers/mathlive.clj shows off a basic demo

  • emmy/portal/mathlive.cljs gives Portal the ability to render MathLive Mathfield instances by loading MathLive into portal's SCI context.

• #31:

  • Adds emmy.jsxgraph, with functions for creating Reagent fragments that configure the components from JSXGraph.cljs for Portal or Clerk

  • dev/emmy_viewers/jsxgraph.clj shows off some basic demos, though these are not yet organized

  • emmy/portal/jsxgraph.cljs gives Portal the ability to render JSXGraph components by loading JSXGraph into portal's SCI context.

• #29:

  • Upgrades viewer dependencies (other than MathBox) to versions compatible with Portal and able to be evaluated via SCI

  • Adds emmy.leva, with functions for creating Reagent fragments that configure the components from Leva.cljs for Portal or Clerk

  • dev/emmy_viewers/leva.clj shows off some basic demos, though these are not yet organized

  • emmy.viewer/fragment now tags its inputs as Reagent components, vs the accidental mafs-specific tagging that existed before. mafs components receive correct metadata to render with or without styling.

  • emmy/portal/leva.cljs gives Portal the ability to render Leva components by loading Leva into portal's SCI context.

• #26:

  • Adds emmy.clerk with support for configuring Clerk projects and specific notebooks with this project's viewers.

    Call emmy.clerk/install! within a notebook to activate viewers, and emmy.clerk/install-css! in your dev/user.clj to configure Clerk with the CSS required to render Mafs and friends.

  • Adds emmy.viewer with metadata augmentation and functions for declaring Reagent fragments that can create reagent.core/atom instances on the client side, and query and manipulate them.

  • Adds emmy.mafs as an aggregate namespace for the new emmy.mafs.{core, coordinates, line, debug, plot}. These namespaces allow you to create Reagent fragments that render in Clerk or Portal using Mafs.cljs, and take advantage of Emmy's compilation wherever possible.

  • Upgrades mafs.cljs to 0.3.0 and clerk-utils to 0.6.0.

  • Adds dev/emmy_viewers/mafs.clj, dev/examples/mafs.clj and dev/examples/portal.clj to the static site published to https://emmy-viewers.mentat.org. (These are still quite scattershot and not built for exposition yet!)

  • Modifies dev/user.clj to launch with a pre-built JS bundle by default, instead of compiling each time. This will make bb clerk-watch or other ways of invoking user/serve! or user/build! much faster.

• #28:

  • Adds Portal support for all existing Emmy-Viewers code via emmy.portal. See emmy.portal/{prepare!, install!, start!}.

    This required the custom viewers emmy.portal.mafs, emmy.portal.tex and emmy.portal.reagent, as well as emmy.portal.deps for installing the NPM deps necessary to make each plugin work.

    I'll continue the pattern here for MathBox, Leva and JSXGraph as they come along.

  • adds emmy.viewer.css with CSS maps for each of the Emmy-Viewers dependencies. Eventually each of these will move down into the appropriate sub-project.
