v0.5.0

This changelog covers changes since version 0.2.0:

• ported to JupyterLab 1.0

• added jumping to the imported module. Examples of supported syntax include:

  • Python 3 (Python 2 was not tested and the kernel resolution is not guaranteed to work):

    • import x,
    • from x import z,
    • import x.y

    alt-clicking on x or y in the above examples lead to an attempt to open relevant module; if a kernel is available (notebook only for now) the path to the source module will be resolved accurately, otherwise a simple guess (e.g. x.py for x) will be used. Relative imports are supported and the location of the file is considered.

  • R:

    • source('abc.R')
    • import::here(fun.1, .from='abc.R')

    in the first example, alt-clicking on source will open abc.R; in the second example, alt-clicking on .from will also open abc.R. This is planned to be extended to cover the string defining the path itself in future versions.

  Note: only files reachable by JupyterLab can be opened (which is limited due to security reasons, however, may be worked around in the future versions).

• fixed regression from v0.1.3 in CodeJumper._findLastDefinition which rejected results of the first filtering step; relevant test case was included

• fixed the element counter (CodeMirrorExtension._countUsagesBefore) mixing up variables and properties instead of focusing on one type only; added tests covering this function

• added more Python jump tests, reuse the testing code

• added test for CodeMirrorExtension.selectToken() with a challenging edge case.
