GitHub行首缩进自动转换致curl脚本执行失败，寻求解决方案

Let's tackle these two frustrating indentation issues with GitHub head-on:

Issue 1: Spaces → Tabs Conversion Breaking Remote curl Scripts #

You mentioned GitHub repeatedly converts leading spaces to tabs, which is tanking your remote curl-executed scripts. This is a common pain point because many scripting languages (like shell scripts) rely on consistent indentation—tabs where spaces were expected can trigger syntax errors or make the script behave unpredictably when run via curl.

Fixes: #

• Enforce per-repository rules with .gitattributes (most reliable for team projects):
  Create or edit a .gitattributes file in your repository root, and define indentation rules for your script files. For example, if you're working with shell scripts:

  *.sh text eol=lf indent-style=space indent-size=4
  

  This tells Git (and GitHub) to treat .sh files as text, use LF line endings, enforce 4-space indents, and disable automatic tab conversion.
• Disable global auto-indent conversion (for your local setup):
  If you want to prevent this across all your repositories, run these commands in your terminal:

  git config --global core.autocrlf false
  git config --global core.indentBlankLines false
  

  Note: Repository-level .gitattributes will override global settings, so use this as a fallback.

Issue 2: Tabs → Spaces Conversion When Saving Unmodified Files #

The second problem—where GitHub converts 4-width tabs back to 2-width spaces when you save a file without editing the indentation—happens because GitHub's web editor has default indentation preferences that clash with your file's existing format.

Fixes: #

• Lock in tab rules with .gitattributes:
  For files that need to keep tabs (like config files or certain scripts), add this to your .gitattributes:

  *.conf text indent-style=tab indent-size=4
  *.txt text indent-style=tab indent-size=4
  

  Replace the file extensions with whatever applies to your use case. This ensures both GitHub's web editor and local Git respect the tab indentation.
• Adjust GitHub web editor settings:
  Go to your GitHub account settings → Appearance → Editor, then set:
  • Indentation style: Tab
  • Indent size: 4
    This changes the default behavior of the web editor to match your desired tab width, so saving unmodified files won't trigger unwanted conversions.
• Local Git configuration check:
  Make sure your local Git isn't auto-converting tabs to spaces. Run this in your repository directory:

  git config --local core.indentBlankLines false
