Are the new features of gantt charts mermaid.js updated?

[corinabioinformatic]

Hello, I noticed there are several updates in mermaid.js when creating a gantt chart like:

• axisFormat
• tickInterval
• First milestone
• Last milestone None of them work using the DiagrammeR library. Is it planned any update about it?

Example:

WORKS FINE:

m0 <- mermaid("
                    gantt
                    dateFormat  YYYY-MM-DD 
                    title Gantt Chart - Project

                    III (263)            :      first_3,  2019-07-16, 2019-09-15
                    ")  %>% 
  style_widget("display:none", "line.today")

# make a copy so we can compare in a tag list later
m2 <- m0

m2$x$config = list(ganttConfig = list(
  # a little tricky setup in what is already a hack
  #  treat this like a filter function with filter as second component in array
  #  and the time formatter in the first
  #  more than likely you will want to know your scale
  axisFormatter = list(list(
    "%b,%Y" # date format to return; see d3 time formatting <-"%d %b,%Y"
    ,htmlwidgets::JS(
      'function(d){ return d.getMonth() }' # filter for Mondays or day of week = 1
    )
  ))
))

m2

DOES NOT WORK. When adding axisFormat line, or tickInterval line or First/Last milestone lines do now work (altough in the mermaid live version works fine (axisFormat workaround here).

m0 <- mermaid("

                    ")  

m0

In which file and folder at mermaid github project could i find this chunck of code to take a look and experiment with those functions too?

DiagrammeR is definitely using an older version of mermaid.js. I've tried 'hacking' the package to use an updated version to no avail. Since it's such a thin wrapper, I'd think this is a simple update but perhaps not? I'd be interested to hear from the DEVs. I'd also be happy to help with this update if they want to provide a baseline level of guidance.

For the time being, I've simply been going to https://mermaid.live/ and saving the code in an R script for posterity. It's not ideal, but it gets the job done.
