I would like to use emacs to enter data -- to start with, essentially a set of numeric responses to a list of questions. The questions will usually be the same every day, but will change slowly over time.
I want the data to be recorded as plain text, but to use a more constrained interface than just typing plain text, so that it's faster to enter the data and less error-prone. For example:
- I would like j and k to move up and down between fields
- I don't want to have to enter say evil's insert state in order to enter numeric values
- I want the names of the questions to be automatically filled in and non-editable
The only code I've seen like this in emacs is org-agenda -- org-habit in particular is quite similar to what I have in mind. However, org is a rather big code base, and though great software, not always the most exemplary elisp code in my book. magit has a somewhat similar approach to interaction, though it happens not to have any UI you'd be likely to describe as "data entry".
Does anything like this already exist? How can I go about implementing something like this?
