[Feature Request]: Multicursor and preserving replacement feature

[johmsalas]

Discussed in #125

Inspired by microsoft/vscode#106502
There is a plugin for vscode https://marketplace.visualstudio.com/items?itemName=Cardinal90.multi-cursor-case-preserve

Compared to the existing VsCode solution, if this feature is implemented in text-case.nvim it can use all the supported Text Cases in the plugin.

Replacement considerations

• When ctrl+d (customizable keybinding) is pressed it will highlight the next occurrence, even if the text case is different as long as the base is the same
• Support for visual mode. It will use the selected text as the base for the considered text variations
• Support for normal mode. It will compute the current word. Taking into account the current word could have characters like _, -, . or /
• Multiline support adds extra complexity, I don't think there is a common use case for this

Multicursor considerations

• It would include custom multicursor selection because regular multicursor plugins/implementations are decoupled from text cases, they do not select different text cases (it becomes unsupported when the text cases are in snake, pascal, ...)
• The multicursor would only support few operations. So far the only known operation is Change Preserving Case. No delete, change, etc... regular keybindings won't work on the selected cursors.
• Once the locations are selected using ctrl+d. There are 2 ways of triggering the Change Preserving Case
  • Pressing c. This is the natural way, but requires to register a keymap on the letter c on visual mode. This could be disruptive to the original c keybinding. Perhaps indications using Hydra?
  • A custom keybinding, ie gax. Unnatural developer experience

Created a draft to outline the code design: #124
Will update this desc when there are more conclusions to keep track of them

sorry to ask ! How did you have a graph like background in neovim?

[johmsalas]

How did you have a graph like background in neovim

@tonmoy998 Do you have a picture or link to that background? Not sure I understand the question

[tonmoy998]

I am asking about the neovim background.I have a clean dark background where you have background like graph

[tonmoy998]

Is it terminal background or Neovim ? 🤔🤔

[johmsalas]

@tonmoy998 Unfortunately, it must be due to the file compression when the image was uploaded. In my current setup, the terminal (iterm2+tmux) has reduced opacity (see the wallpaper is visible behind the words on the right panel), yet Neovim is 100% opaque and I didn't put more time to solve it, perhaps the theme background?

[tonmoy998]

Ok.Thank you

[tonmoy998]

Cool! Fixed it ;)

[johmsalas]

@tonmoy998 would you mind sharing the solution?

[tonmoy998]

@johmsalas Nothing special.I made kitty background to an image.And made neovim transparent with this https://github.com/xiyaowong/transparent.nvim.
