`config.tab_spaces` defaults to `nil`, preserving literal tabs. Set an integer from `1` through `255` to insert that many spaces per Tab in Insert mode, at every caret. This is a fixed count, not alignment to the next tab stop; it does not change how existing tab characters are displayed.
`config.language_tab_spaces` defaults to `{}`. It overrides the global setting for the active buffer's detected syntax language, using the case-sensitive names shown in the language bar, for example `{ "Rust" => 4, "Ruby" => 2, "Python" => 4, "Makefile" => nil }`. A `nil` override preserves literal tabs for that language, even when the global setting uses spaces. Unlisted or unknown languages and unnamed buffers without a recognized shebang use `tab_spaces`. Detection reuses syntax highlighting's filename, extension, and shebang rules, independently of whether an LSP is enabled.
`config.language_tab_spaces` defaults to `{}`. It overrides the global setting using the same case-sensitive language IDs as `config.lsp`, for example `{ "rust" => 4, "ruby" => 2, "python" => 4, "makefile" => nil }`. Syntax detection and built-in LSP presets share canonical IDs rather than maintaining separate naming conventions; other bundled IDs include `shellscript`, `cpp`, and `typescriptreact` for Bash, C++, and TSX. Display labels such as “Ruby” remain presentation-only. A `nil` override preserves literal tabs for that language, even when the global setting uses spaces. Unlisted or unknown languages and unnamed buffers without a recognized shebang use `tab_spaces`. Detection reuses syntax highlighting's filename, extension, and shebang rules, independently of whether an LSP is enabled.
Active snippets retain Tab/Shift+Tab argument navigation; after the final stop, Tab uses the configured insertion setting. Explicit Tab bindings still take precedence, and Ctrl+i remains a Tab alias. Bracketed paste, clipboard paste, completion payloads, and plugin text retain literal tab characters. Insert undo/redo and dot repeat preserve the resolved spaces or tab. Widths other than `nil` or integers in `1..255`, non-hash language overrides, and empty, non-string, or control-containing language keys reject the configuration.
