如何设置Notepad++中SQR自定义语言的大小写无关if...end-if代码折叠？

Got it, let's fix that SQR code folding issue in Notepad++ specifically for case-insensitive if...end-if blocks—here's how to do it step by step:

• Go to Language > User Defined Language > Define your language...
• If you already have your custom SQR language set up, select it from the top dropdown. If not, click New and name it "SQR" to start fresh.

Switch to the Folding in code 1 tab—this is where we'll define our target foldable blocks:

• In the Open field: paste (?i)if — the (?i) regex flag makes the match case-insensitive, so it catches If, IF, iF, or any mixed-case variation of "if".
• In the Close field: paste (?i)end-if — same flag applies here, so it matches End-If, END-IF, etc.
• Set the Type dropdown to 1 (the standard block folding type).
• Critical: Delete or clear any existing open/close pairs in this tab (or other folding tabs) that might be causing unwanted folding (like procedure or loop blocks).

Head to the General tab of your custom language settings:

• Make sure the Folding checkbox is checked (this ensures Notepad++ applies your folding rules to the language).

• Click Save As to save your updated SQR language definition.
• Close the User Defined Language Manager, then open an SQR file and set its language to your custom SQR definition.
• Test the folding: look for the small +/- icons next to lines with if statements—only those if...end-if blocks should fold, regardless of case, and no extra unwanted folding should occur.

• If you still see random folding, double-check all Folding in code tabs (1, 2, 3) to ensure no extra open/close pairs are accidentally defined.
• If the case-insensitive match isn't working, confirm you included the (?i) prefix in both the open and close patterns—this is non-negotiable for ignoring case.
• Restart Notepad++ if changes don't take effect immediately; sometimes the app needs a refresh to pick up updated language rules.
