image capture keybinding and configs

[linuxcaffe]

Let\s say you wanted to process a big box of receipts AND you wanted to scan each one as you go. This feature request is for support of capture, naming and taming of image files related to transactions.

Capture support could take the form of a keybinding that invokes a user-definable script, that;

• triggers the image-capture/ scan of the source document
• uses pre-defined locations (config file) for both image file(s) and physical document(s)
• produces files named like $DATE_$DESCRIPTION.$EXT
• adds transaction comment tags like ' ; scan: $FILE_LOCATION/$DATE_$DESCRIPTION.$EXT'
• adds transaction comment tags like ' ; document: $DOC_LOCATION # tracking the source paper file

How exactly webcam/ smartphone/ scanners are triggered and what process the image files undergo, is beyond the scope of this suggestion. This issue is really more of a discussion-starter.

This is very specific. I think a reasonable general approach would be to pipe the current transaction to a user-definable script and read the modified transaction back again. This would allow to do arbitrary transformations on the transaction, including the addition of tags.

simonmichael/hledger#501 could be useful for this.

well.. yeah!
