6395 :: Editing single input line

• Mice (orginal) [2020-06-01T14:57:02+02:00] view original

  Hey!

  I'm writing a CLI. Getting input with readLineFromStdin() from rdstdin works fine. (except: when deleting with backspace, unicode characters are not removed entirely, but it's not a big problem)

  I'd like to implement an edit functionality, i.e. readLineFromStdin() but with a "default value".

  So the default value is already in the buffer and the user can remove/add/edit characters.

  Example use case:

  1. User inputs single line text
  2. CLI asks for verification
  3. User catches an error and would like to edit their previous input
  4. CLI shows editable input with the previous input already filled in

  I don't want to uses curses if possible, I'd like to keep it simple and "inline".

  I looked into the linenoise docs, but it seems like I can only add "history" and "completion". It's not the best if the user has to make same action to get the previous input in the mentioned use case.

  Any suggestions?

  Thanks in advance!

  Any ideas on how to solve this issue? It would be useful for my idea incubator CLI app: https://github.com/qwhex/nimspire I'm considering rewriting it in Rust because Nim's doc is pretty sparse :(

  I couldn't edit my original post (archived), but here's a shorter version:

  I'd like to implement an edit line functionality, so something similar to readLineFromStdin() but with a "default value".

  So the default value is already in the buffer and the user can remove/add/edit characters.

  Example use case:

  1. User inputs a single line of text
  2. The CLI app shows the inputted text and asks for verification
  3. The user finds a typo in the text
  4. The app shows an editable input with the previously inputted line already filled in

  In my app, currently I can only implement an edit idea functionality by requiring reinputting the whole line again.

  there's a linenoise wrapper in the stdlib that has support for history, or there's illwill which is more full-featured and all-Nim

  A pure Nim version of linenoise
