# MD010 - Hard tabs Tags: whitespace, hard_tab Aliases: no-hard-tabs Parameters: code_blocks (boolean; default true) This rule is triggered by any lines that contain hard tab characters instead of using spaces for indentation. To fix this, replace any hard tab characters with spaces instead. Example: Some text * hard tab character used to indent the list item Corrected example: Some text * Spaces used to indent the list item instead You have the option to exclude this rule for code blocks. To do so, set the `code_blocks` parameter to `false`. Code blocks are included by default since handling of tabs by tools is often inconsistent (ex: using 4 vs. 8 spaces).
