Review of actions from previous meeting

Actions from last time, and their status are:

  • Daniel and Lars to keep an eye on the FOSDEM CfP (30th Nov) and together decide if/where to submit a talk.
    • we had a preview of the CFP for the “safety and open source” devroom
    • there’s no deadline for the CFP responses yet, but we’d like to submit our proposal early, within a week
    • we’ll need to have a title, subtitle, one-paragraph abstract, an optional longer description, and some relevant links

Review of the iteration that has ended

Subplot milestone 40 had the following issued closed:

Additionally, we upped the Minimum Supported Rust Version to 1.56 (Subplot issue 258).

We made little progress on:

We made significant progress on:

  • Subplot issue 141 subplotlib: Needs better test suite
    • Daniel did what he meant to do, but it’s a tracking issue, and he opened a new blocker issue

We moved most of the remaining open issues to the next milestone (Subplot milestone 41) and then closed off this iteration.

Review of the repositories

Currently open MRs:

  • subplot: none
  • subplot-web: none
  • subplot-container-images: none

Extra branches unrelated to MRs:

  • subplot:
    • subplot-rust – Daniel is keeping this around until he has completed the work on Subplot issue 141.
    • docgen-cmark – Lars is working on making docgen use cmark rather than pandoc for the initial parse and processing.
  • subplot-web: none
  • subplot-container-images: none


  • subplot: clean
  • subplot-web: none
  • subplot-container-images: clean, and we triggered the one to build a new container image

Current goal (goal 2; not changed for this iteration)

Subplot provides a set of libraries with identical capabilities in each of the supported languages. Python remains a supported language. Rust is promoted to supported-language status. Subplot will be tested with all supported languages. In addition, any quality of life improvements which can be done shall be done. This goal will be considered complete when a release of Subplot has been made with the unified language handling support complete.

Length of this iteration

The year-end holidays are coming, so we decided to make this a month-long iteration. The next planned meeting is January 1.

Issue review

We had 51 open issues at the start of the meeting.

We reviewed non-someday-maybe issues for subplot that have been changed since thee previous meeting.

We made the following changes:

  • Subplot issue 214 Lacks example and docs for using Rust step functions
    • put into iteration
    • assigned to Lars
  • Subplot issue 251 and Subplot issue 252 will probably go away now that our MSRV has been raised
  • Subplot issue 255 __
    • uses of the word graph exposed to users should change, but it’s not urgent
    • we adjusted labels
  • Subplot issue 256 Lacks way to mark an embedded file as being OK that it’s not used in a scenario
    • adding .example that’s like .file, with the same typesetting, but that can’t be used as an embedded file is probably the way to go
    • adjusted labels
  • Subplot issue 259 Top level subplots should be run in Rust too
    • put into iteration
    • assigned to Daniel
    • adjusted labels

We left the docker-for-subplot issue alone, and subplot-web had no issues.

Other discussion

  • We had a discussion and agreed that goal 2 doesn’t need significant QoL changes right now. We may drop of the issues currently assigned to goal 2.

Plan for next iteration

We opened Subplot milestone 41 to cover this iteration, with the following issues:

Other business

  • We decided to make a release of whatever is in the main branch and label it 0.3.2 or 0.4.0, depending on whether it has breaking changes or not. Subplot issue 254

  • We are not yet ready to file an RFP bug to get Subplot packaged for Debian. It will happen after we think we won’t be making breaking changes anymore. We probably want to do a review of the dependencies as well, to make packaging easier.

  • We are not yet ready to make a whole code base review of Subplot. However we feel at least part of the new goal 3 will be reviewing a portion of the code. Lars made the pandoc-filter-diagram crate from Subplot code, and intends to refactor Subplot to use it eventually.

  • We will switch an issue based agenda when other people join the meeting.

  • We won’t be reaching out for feedback until goal 3 is done.

  • We’ll aim at the FOSDEM “safety and open source” devroom for now. After we’ve made that talk, whether it’s accepted or not, we will consider other conferences and also podcasts.

  • Regarding the media repository question - we believe this is premature at this point - once we are ready to write the talk mentioned above, it will be time for the repository.

  • Lars will be opening communications with the WMF around supporting their use of Subplot for scap.


  • Lars will open an issue to use pandoc-filter-diagram.

  • Lars will approach WMF about how scap uses Subplot.
