v3.4.1

This release fixes an issue with installation from source (via JupyterLab Extension Manager or jupyter labextension install) failing to build when jupyterlab-classic was not installed. The installation using pip or conda is recommended over source installations.

To learn more about precious changes introduced in version 3.4, or to see the recommended installation instructions please see: v3.4.0

Changelog:

• bug fixes:

  • fixed installation of the source version of the extension (causing build error if classic was not installed) (#526)

v3.4.0

This release provides notable improvements and bug fixes to the completer (sorting, completion in strings, rendering of markdown documentation) and to the diagnostics panel (when foreign documents like %%R, or %%sql cells are used). The long paths in the status popover will not be collapsed to prevent it from spanning a large portion of the screen; you can get the full path by hovering over the collapsed path. The ambiguous suppressInvokeIn setting was replaced by suppressContinuousHintingIn and suppressTriggerCharacterIn settings; if you customized it before please update the settings accordingly.

To upgrade to this release:

1. Make sure your JupyterLab version is 3.0.x

2. Update the extension:

   pip install jupyterlab-lsp==3.4.0 jupyter-lsp==1.1.3
   # or, for conda:
   # > Please note that conda packages may take a day or two since release before becoming available!
   # conda install -c conda-forge jupyterlab-lsp=3.4.0 jupyter-lsp=1.1.3

3. Note:

• If installing this extension for the first time, please read the full installation instructions as language servers of your choice need to be installed too, and additional configuration can make your experience smoother.
• If you wish to use a recent jedi-language-server (versions 0.22+) please make sure to upgrade IPython to 7.20 to avoid this issue.

Changelog:

• features:

  • the priority of the completions from kernel can now be changed by switching new kernelCompletionsFirst setting (#520)
  • completer panel will now always render markdown documentation if available (#520)
    • the implementation re-renders the panel as it is the best we can do until jupyterlab#9663 is merged
  • the completer now uses filterText and sortText if available to better filter and sort completions (#520, #523)
  • completer suppressInvokeIn setting was removed; suppressContinuousHintingIn and suppressTriggerCharacterIn settings were added (#521)
  • suppressContinuousHintingIn by default includes def to improve the experience when writing function names (#521)
  • long file paths are now collapsed if composed of more than two segments to avoid status popover and diagnostics panel getting too wide (#524)

• bug fixes:

  • user-invoked completion in strings works again (#521)
  • completer documentation will now consistently show up after filtering the completion items (#520)
  • completions containing HTML-like syntax will be displayed properly (an upstream issue) (#520, #523)
  • diagnostics panel will no longer break when foreign documents (e.g. %%R cell magics) are removed (#522)

v3.3.1

This release improves the completer and signature behaviour on focus loss and brings other UX improvements to the completer behaviour (see the changelog notes below). With jupyter-lsp 1.1.3, the JupyterHub/Binder users should no longer be required to switch to to jupyter_server to get this extension working.

To upgrade to this release:

1. Make sure your JupyterLab version is 3.0.x

2. Update the extension:

   pip install jupyterlab-lsp==3.3.1 jupyter-lsp==1.1.3
   # or, for conda:
   # > Please note that conda packages may take a day or two since release before becoming available!
   # conda install -c conda-forge jupyterlab-lsp=3.3.1 jupyter-lsp=1.1.3

3. Note:

• If installing this extension for the first time, please read the full installation instructions as language servers of your choice need to be installed too, and additional configuration can make your experience smoother.
• If you wish to use a recent jedi-language-server (versions 0.22+) please make sure to upgrade IPython to 7.20 to avoid this issue.

Changelog:

• bug fixes:

  • completion and signature suggestions get invalidated when editor changes (#507)
  • signature suggestions now invalidate on cursor move to another line or backwards too (#507)
  • LaTeX is now rendered in documentation panel of completer (#506)
  • completion response returned as plain text use pre tag to retain whitespace formatting (#506)
  • pre-formatted code font size was reduced to match font-size of the text in completion panel (#506)
  • completer no longer spans the entire screen if it has long entries (#506)
  • add config for the classic notebook server extension (#504)

This is a bugfix-only release for the older version of JupyterLab 2.2.x. We recommend upgrading to JupyterLab 3.0.x and extension 3.x to benefit from the improvements made in the 3.x releases. Many thanks to @jtpio for backporting the changes and driving this release.

To upgrade to this release:

1. Make sure your JupyterLab version is 2.2 (for JupyterLab 3.0 please use the never extension versioned 3.x)

2. Install/update LSP packages:

pip install jupyter-lsp==0.9.3
jupyter labextension install @krassowski/jupyterlab-lsp@2.1.3

Changelog:

bug fixes:

• backport: connection manager now properly keeps track of notebooks when multiple notebooks are open (#474, #486)
• backport: notebook (and diagnostics panel) state is now properly updated after rename or kernel restart (#499)

v3.3.0

This release improves overall speed and experience of the completer, including new configuration options and bug fixes, notably a major stability fix Windows.

v3.0.0

This release provides support for JupyterLab 3.0. Many thanks to everyone who helped to port the extension: @martinRenou, @jtpio, @bollwyvl, and @karlaspuldaro.

To upgrade to this release:

0. JupyterHub users: please see https://github.com/krassowski/jupyterlab-lsp/issues/375#issuecomment-761078622

1. Make sure your JupyterLab version is 3.0 and uses jupyter_server:

   jupyter server extension list       # note: a space between "server" and "extension"

   should include:

   jupyterlab enabled
   - Validating jupyterlab...
     jupyterlab 3.0.0 OK

   if you get an error (jupyter-server: command not found) instead, you are probably using the old notebook server rather than the new jupyter_server, most likely due to having an older JupyterLab version installed.

2. Uninstall the old versions (if installed) - this step may not be necessary, but is recommended anyways

   pip uninstall jupyter-lsp    # or and equivalent for conda (depending on which conda package you installed)
   jupyter labextension uninstall @krassowski/jupyterlab-lsp

3. Install the new JupyterLab 3.0-compatible version:

   # note that it is jupyter**lab**-lsp now
   pip install jupyterlab-lsp==3.0.0
   # or, for conda:
   # conda install -c conda-forge jupyterlab-lsp=3.0.0

4. Validate that the installation succeeded:

   jupyter labextension list         # note: **no** space between "lab" and "extension"

   should include:

   @krassowski/jupyterlab-lsp v3.0.0 enabled OK (python, jupyterlab_lsp)

If you are installing this extension for the first time, please read the full installation instructions as language servers of your choice need to be installed too, and additional configuration can make your experience smoother.
