Interactive mode

[YodaEmbedding]

sd can be useful in situations for typical search and replace. It would be nice to have an --interactive flag so that we can "yes" or "no" or "default" (== yes?) to a particular replacement.

@YodaEmbedding I definitely agree. Do you have any ideas on what the UI/UX would look like?

A very rough sketch is below. Some of the keystrokes are copied from git add -p (e.g. [A], [D]) to reduce the learning curve.

Preview:

Once upon a midknight dreary, while I pondered, weak and weary,
I ate some lovely [midknight] valencia oranges.
While I nodded, nearly napping, suddenly there came a tapping,
As of some one gently tapdapping while eating midknight valencia oranges.

-------------------------------------------------------------------------

filename.txt            line 2 / 1024

From: midknight
To:   midnight

[Y] yes
[N] no
[A] yes to rest of file
[D] no to rest of file
[J] next
[K] previous
[Q] quit, save changes
[!] abort, do not save file(s?)

An alternative format would be something like:

filename.txt:
Y 1:    Once upon a [midnight] dreary, while I pondered, weak and weary,
> 2:    I ate some lovely [midknight] valencia oranges.            <== current line
N 4:    As of some one gently tapdapping while eating [midknight] valencia oranges.

someotherfile.txt:
[...]

[Y] yes
[N] no
[A] yes to rest of file
[D] no to rest of file
[J] next
[K] previous
[Q] quit, save changes
[!] abort, do not save file(s?)

...with some colors to highlight replacements, search matches, the current line, etc.

Open questions:

• How much context does the user need? (a line? surrounding lines?)
• Word wrapping?
• Should the file be modified immediately upon a [Y]?
• Should the file be modified immediately after we have done all replacements?
• Should the output of the preview window be modified immediately upon a [Y]?
