Download *.jar from Releases. 12 | 2. Deploy it to `GITBUCKET_HOME/plugins`. 13 | 3. Restart GitBucket. 14 | 15 | ## Usage 16 | 17 | Store `.ipynb` file (from File->Download as->Notebook) to your Git repository and push it to GitBucket. 18 | If you don't know using IPython/Jupyter, try google it! 19 | 20 | ## Limitations 21 | 22 | - Javascript output is disabled. 23 | - traceback is not correctly rendered(not supported ANSI escape sequences and tabs.) 24 | - only support version 3.0/4.0 ipynb files. 25 | - only tested Python2 kernel. 26 | 27 | ## BugReport 28 | 29 | If your `.ipynb` is not correctly displayed, please make an issue with your `.ipynb` file if you can. 30 | 31 | -------------------------------------------------------------------------------- /.github/workflows/scala.yml: -------------------------------------------------------------------------------- 1 | name: Scala CI 2 | 3 | on: [push, pull_request] 4 | 5 | jobs: 6 | build: 7 | 8 | runs-on: ubuntu-latest 9 | 10 | steps: 11 | -
