NVim Theme Modifier

Changes theme accents based on current NeoVim mode.

Currently works for the following modes:

• Normal
• Insert
• Visual

Set the color for each mode to match your theme in settings.json (see below)

Requirements

You will need the NeoVim VScode extension installed for this to work - Neovim Extension - follow full setup before continuing

Config

** WARNING: The plugin will add / override the following keys in settings.json - workbench.colorCustomizations:

"workbench.colorCustomizations": {
    "activityBarBadge.background": "#ffc600",
    "editorCursor.foreground": "#ffc600",
    "inputValidation.errorBorder": "#ffc600",
    "panel.border": "#ffc600",
    "panelTitle.activeBorder": "#ffc600",
    "panelTitle.activeForeground": "#ffc600",
    "peekView.border": "#ffc600",
    "peekViewTitleLabel.foreground": "#ffc600",
    "tab.activeBorder": "#ffc600",
    "statusBar.border": "#ffc600"
}

In settings.json:

You can change the colors to match the theme you use:

    "workbench.nvimColorNormal": "#ffc600",
    "workbench.nvimColorInsert": "#D32F2F",
    "workbench.nvimColorVisual": "#673AB7",

In Vscode Vimrc:

This will need adding to you rvimrc, it tells neovim to send a command to vscode changing the color in a hacky way (can't find a better way, no AUTOCMDS for visual, replace etc,,,)

Make sure to restart VSCode after adding this config

Known Issues

• Visual mode puts the cursor to the start of the line. Negligable as following command is almost always to move the cursor

TODO

• search mode
• replace mode
