Code::Blocks代码补全匹配异常及显示不全问题求助

Hey there, let's tackle those two Code::Blocks code completion issues you're facing—they're pretty common, so we've got straightforward fixes for both!

1. Fixing Incorrect Completion Matches (e.g., "bass_l" showing "bass_i" results) #

This usually happens when the symbol index powering code completion is outdated or corrupted. Try these steps:

• Rebuild project symbols: Open your project in Code::Blocks, go to the top menu bar, click Project → Rebuild symbols. This forces the IDE to re-scan all your project's headers and source files, updating the symbol database that drives completion. It's the quickest fix for most matching weirdness.
• Reset Code::Blocks cache: If rebuilding symbols doesn't work, head to your user directory (Windows: C:\Users\<YourName>\.codeblocks; Linux/macOS: ~/.codeblocks) and delete the symbols or cache subfolders. Restart Code::Blocks afterward—it'll rebuild the cache from scratch, which often clears up stubborn indexing issues.
• Check case sensitivity settings: Go to Settings → Editor... → Code completion → C/C++ specific. Make sure the Case sensitivity option is set to your preference—toggling it to "Sensitive" can tighten up matches if you want strict prefix matching.

2. Fixing Truncated Completion Lists (Content Cut Off by Screen) #

If your completion list can't display all options without going off-screen, try these tweaks:

• Increase list size limit: Go to Settings → Editor... → Code completion. Look for the List size field (it controls the maximum number of items shown). Bump up the value from the default (usually 10) to 20 or 30—this lets more items fit in the list before it gets cut off.
• Use keyboard navigation: Even if the list goes off-screen, use the Up/Down arrow keys to scroll through all options. The selected item will show a full preview in the tooltip (if enabled), so you'll still see the full symbol name even if it's not visible in the list.
• Adjust editor font size: If long symbol names get truncated horizontally, go to Settings → Editor... → General settings → Font and reduce the font size slightly. This gives each line more space to display longer names without wrapping or cutting off.
