When UiParams Is Changed Via `updateOptions` And `redraw` Actions, It Doesn't Work.

When uiParams is changed via updateOptions and redraw actions, It doesn't work

When working with the DDU (Denops Dialog Utility) plugin in Neovim, you may encounter issues with updating the UI parameters using the updateOptions and redraw actions. In this article, we will explore the problem of uiParams not being updated correctly when changed via these actions.

When you change uiParams like winHeight via updateOptions and redraw, the UI's height does not change as expected.

The corresponding part of the UI should be updated accordingly when uiParams is changed.

To help diagnose the issue, we need to provide some environment information:

• ddu.vim version (SHA1): 05eb23b
• denops.vim version (SHA1): 4ff8f35
• deno version (deno -V output): deno 2.0.6
• OS: Ubuntu 22.04.5 LTS on Windows 10 x86_64
• neovim/Vim version output: NVIM v0.11.0-dev-1540+ga3ef29d570

To reproduce the problem, we need a minimal init.vim/vimrc configuration without plugin managers. Here is an example configuration:

" Add Denops and DDU repositories
set rtp+=~/.cache/dein/nvim/repos/github.com/vim-denops/denops.vim
set rtp+=~/.cache/dein/nvim/repos/github.com/Shougo/ddu.vim
set rtp+=~/.cache/dein/nvim/repos/github.com/Shougo/ddu-ui-ff

" Define a function to set up DDU settings
function! s:ddu_my_settings() abort
    " Map the 'u' key to update options and redraw the UI
    nnoremap <buffer> u
                \ <Cmd>call ddu#ui#multi_actions([
                \        [
                \            'updateOptions',
                \            #{
                \                uiParams: #{
                \                    ff: #{
                \                        winHeight: 3
                \                    }
                \                }
                \            },
                \        ],
                \        ['redraw', #{ method: 'uiRedraw' }],
                \ ])<CR>
endfunction

" Call the function to set up DDU settings
autocmd FileType ddu-ff call s:ddu_my_settings()

To reproduce the problem, follow these steps:

1. Open Neovim with the minimal init.vim/vimrc configuration: nvim -u init.vim
2. Type :call ddu#start(#{ ui: 'ff' }) to start the DDU dialog
3. Type u in the DDU window to update the options and redraw the UI
4. Observe that the UI's height does not change as expected

When uiParams is changed via updateOptions and redraw actions, It doesn't work: Q&A

In our previous article, we explored the issue of uiParams not being updated correctly when changed via updateOptions and redraw actions in DDU. In this article, we will provide a Q&A section to help answer some common questions related to this issue.

A: The expected behavior is that the corresponding part of the UI will be updated accordingly when uiParams is changed.

A: This issue is likely due to a bug in the DDU plugin or a misconfiguration in your init.vim/vimrc file. We recommend checking the DDU documentation and your configuration to ensure that everything is set up correctly.

A: To troubleshoot this issue, you can try the following steps:

1. Check the DDU documentation to ensure that you are using the correct syntax and options.
2. Verify that your init.vim/vimrc configuration is correct and up-to-date.
3. Try updating uiParams using a different method, such as using the ddu#ui#updateOptions function directly.
4. Check the DDU logs for any error messages or warnings that may indicate the cause of the issue.

A: No, this issue is not specific to the winHeight option. You may experience similar issues with other uiParams options as well.

A: Yes, you can try using a different plugin that provides similar functionality to DDU. However, keep in mind that you may need to modify your configuration and workflow to accommodate the new plugin.

A: If you are interested in contributing to the DDU project, you can start by:

1. Reviewing the DDU documentation and code to understand the issue and potential solutions.
2. Creating a pull request with a fix for the issue.
3. Engaging with the DDU community to discuss the issue and gather feedback.
