troubleshooting

When your output image looks like this:
you have a circle in your output data.

csv example data:

example file

sparkasse csv export is in latin1 :(

TODO list:

• clear input buffer before requesting input
• catch ctrl-c in enter labels to redo the regex
• way to skip csv lines in cli prompt
• fix circles
  • in streams capital first letter
  • out streams small
• is csv header correct if creating new regex_labels.csv
• cli parameters
  • show all = see all entries as final labels
• cli ui
  • HARD: color labels while typing if they exist already to see if they're written correctrly
  • HARD: label autocomplete
  • HARD: regex see what matches?
• generate image automatically
  • is there an api for https://www.sankeymatic.com/build/?
  • download and render local with the sankeymatic js source?
• missing checks:
  • with sankeymatic.com you are not allowed to have circles. circle detection is missing circles are quite easyly created with a regex, and a company refunding something!
• tests
