• Properly bumped the version number in version.txt.
• Fixed tutorial.ipynb.

Very small update, but bumped the version number because the plotly package API is broken, due to the dependency on the new go-plotly version. A trivial update, if you have problems, just update your go-plotly dependency as well.

It also adds the plotly.DarkTheme, plotly.Seaborn and GGPlot2Theme that can be used in your Plotly figures (based on plotly.io Python package).

• Package plotly:
  • Updated go-plotly dependency to v0.7.0. It breaks compatibility, with a new version of the grob package, now imported as grob "github.com/MetalBlueberry/go-plotly/generated/v2.34.0/graph_objects".
  • PlotlySrc updated to "https://cdn.plot.ly/plotly-2.34.0.min.js".
  • Added themes (extracted from the Python library) that can be used as parameters to Layout.Template.

• Updated dependencies:
  • Bumped go-plotly dependency to v0.7.0.

• New --version and -V flags to print version; Improved %version output. (#158)
• Clean up, refactorings and fixed context leakage.
• Added version.txt with target version for build.

• Reverted replace directive: contrary to what the AI suggested, it doesn't work when running from outside a cloned repository.
  • Temporary solution, as this leaves gonb "at the mercy" of the default GOPROXY proxy.golang.org continuously proxying
    the now extinct packages under go.lsp.dev. See #157
  • See more in: go-language-server/jsonrpc2#28
  • v0.10.9 skipped: issues with the release and GOPROXY. Instead I skipped the version.

  • v0.10.9 skipped: issues with the release and GOPROXY. Instead I skipped the version.

• Added a replace directive from go.lsp.dev/{jsonrpc2,uri,protocol} to github.com/go-language-server/{jsonrpc2,uri,protocol} in go.mod, since go.lsp.dev seems to be down.
• Updated dependencies to go.lsp.dev/uri and go.lsp.dev/protocol.
• Set MIMEType KernelLanguageInfo.MIMEType, which enabled auto-complete with VSCode+Polyglot to work with GoNB+Auto-complete. Thanks @tonidy for the find and fix. More in https://github.com/dotnet/interactive/issues/3511
• Updated Dockerfile to build the docker from main/HEAD.

• Improved autostart logic: it now requires being mounted as "readonly" under /root/autostart.
• Added %version, and environment variables GONB_VERSION, GONB_GIT_COMMIT.
• Added %help info on missing environment variables.
• Added stack traces to protocol parsing errors.
• Include function comments in the generated code. This makes tags like //go:noinline work. See #150

• Added dom.SendAsDownload to send data from cells to the client by triggering a browser download. #134

• Issue #131: proper handling of tuple variable declarations like var contents, _ = os.ReadFile(...)

• go1.23, and update dependencies.
• Fixed GitHub's go.yaml actions, test shows green now.

• Fixed some typos in klog formatting.
• Updated dependencies.
• Updated gopls dependencies: new jsonrpc2 API.
• Added LoadScriptModuleAndRun.
• Added Plotly Javascript support, in gonbui.plotly package. Also added example in tutorial.
• During installation, consider /var/folders also a temporary directory.

• Added instrumentation to Jupyter input boxes in nbexec.
• Added functional tests for input boxes created with %with_inputs, %with_password or gonbui.RequestInput.
• Added logo to installation.

• Cache is by-passed if cache key is set to empty ("").
• New widgets demo, using GoMLX's Flowers Diffusion demo
• Updated Dockerfile to start from /notebooks directory, and with instructions to mount the host current directory in the host/ subdirectory. More in #78
• Fixed gonbui.RequestInput.

• Widgets:
  • Normalized API across widgets, so they all look the same -- breaks the API, apologies.
  • Added widget.Select for a drop-down menu.
  • Improved integration tests.
• nbexec: changed javascript code to use the public API jupyterapp.commands.execute instead.

• Fixed Darwin (and other non-linux, that are unix-like) build -- see #74.
  • Added cross-compilation to darwin/arm64 test in run-coverage.sh

• Removed left-over debugging messages.
• Removed left-over replace rule from tutorial.

• Added widgets support (experimental):
  • a websocket opened from the front-end that communicates to the kernel, and through it to the users cells.
  • API to use it in gonb/gonbui/widgets.
  • API to communicate with front-end in gonb/gonbui/comms.
    • Listen[T](address) function added to create a channel listening to front-end updates.
    • Added --comms_log flag to add verbose logging to the Javascript console.
  • API to manipulate the DOM in gonb/gonbui/dom.
    • Persist() added to persist transient changes to the DOM -- meaning dynamically generated HTML and widgets will show up when exporting to HTML or when running nbconvert.
• Added gonb/cmd/nbexec to execute notebooks for integration testing -- nbconvert --execute was not working.
• Added "%wasm" support (experimental):
  • Allows compiling cell to WASM and running that in the notebook. One can write widgets like this. Experimental: there are some use cases are not 100% clear. See "%help" for details on how this works.
  • Added also github.com/janpfeifer/gonb/gonbui/wasm library with some basic helpers to write WASM widgets.
  • Added gonb/examples/wasm_demo.ipynb with a couple of examples of Wasm.
• Improved logging of errors; pre-checking for duplicate package, with improved error message.
• Handle incoming messages in a separated goroutine, so asynchronous/concurrent messages can be handled. Specially important when executing cells that take a long time.
  • Serialize "execute_request" and other "busy" type of requests, so they are executed in the order they are received.
• Added support for %env VAR=VALUE syntax as well (like ipython uses).
• Refactored internal packages to internal/ subdirectory.
