Out Files

Depending on the plot target you choose, dedav4s may produce temporary files. For example if you choose to produce a png, svg or pdf file, these will be written to disk as temporary files. You may find them in the path of the returned value of the plot function.

Where do the temporary files live?

By default, the OS temp directory.

You may specify the location of temporary files through configuration. Either by having a suitably located "application.conf", or by passing in the environment variable DEDAV_OUT_PATH.

e.g.

set DEDAV_OUT_PATH=/Users/simon/Pictures scala-cli

Assuming you have a chart, produced with one of the desktop targets (browser, tempFile, png, svg, pdf)

import viz.PlotTargets.tempFileSpec
import viz.Plottable.*
import viz.vegaFlavour
val chart = viz.vega.plots.SpecUrl.BarChart.plot
// chart: Unit | Path = /tmp/plot-6465606393353479065.txt
chart match
  case _: Unit => ()
  case p: os.Path => println(p)
// /tmp/plot-6465606393353479065.txt

It's location is in the tmpPath field of your chart. You could take advantage of the excellent os library and knowledge of the path of the file, to subsequently move it around. For example if you wish to automate producing a presentation via a script.
