GitHub user zyratlo created a discussion: Managing R support in main and deployments when the R runtime is installed separately
R UDFs run through texera-rudf, a package installed separately because it depends on rpy2 (GPLv2), which is not compatible with the Apache license (see #4155). The rest of R support still lives in main, and each piece is handled on its own. I ran into this while adding R to the notebook migration tool (#8009) and wanted to raise it. ### R in main today * `RUDF` and `RUDFSource` operators, listed under an R group in the operator menu * `r.path` in `udf.conf`, passed to Python workers as `R_HOME` * R mode in the code editor * An R UDF guide in the agent service prompt * Example R UDFs in pytexera * Soon, an R option in the migration tool (#8911, #8912) ### How each part offers or restricts R Every part makes its own decision, and none of them knows whether texera-rudf is installed: * **Operator menu:** always shows the R group. * **Agent service:** adds the R UDF guide to an agent's system prompt unless that agent's allowed operator list is set and leaves out `RUDF`. An empty list means all operators, so by default every agent is taught to write R UDFs. * **Code editor:** always opens R operators in R mode. * **Migration tool:** will have its own flag, `rNotebookMigrationEnabled`, default off. * **Execution:** the Python worker imports texera-rudf only when an R operator runs. If it is missing, the run fails with an install hint. So a user can be offered R by the menu or the agent, build a whole workflow, and only learn at execution time that R is not available. None of our images install texera-rudf, so out of the box no deployment can run R. ### Questions 1. Should one R setting control all of this, hiding the operators, the agent guide and the migration option together? 2. Should it be a config flag, or detected from whether texera-rudf is installed? 3. Should there be an image option that installs R and texera-rudf? 4. How can we streamline managing these types of situations for active deployments?
