Bracket or brace matching and completion

When the cursor reaches an opening or closing brace { }, square bracket [ ] or parentheses ( ), Padre automatically highlight the pair of the braces.

    ()    # Brackets
    []    # Square Brackets
    {}    # Braces
    ''    # Single-Quoted String Literals
    ""    # Double-Quoted String Literals

• brace implies (Brackets, Square Brackets & Braces)

Perl -> Find Unmatched Brace (brace)

Initial observations,

• works in current editor, does not require the file to be saved :)
• highlights the last unmatched ;-(
• I think it must be counting charter types, with little reference to Perl syntax ;-(

This file passes, this is rubbish ;-((

elsif (( $hour < 23 )  { print "Good night.\n"; })  ### added ()

else { print "sleep well!\n;" }

run against Padre r14200

Opps should have run the Syntax Checker first, or should I

• the editor appears to highlight matching braces in luminous green :)

Edit-> Brace Matching (brace) Ctrl+1

• moves the cursor for you
  • If the cursor is outside a brace, it matches to the outside of it's pair. either forward or backwards :)
  • If the cursor is inside a brace, it matches to the inside of it's pair. either forward or backwards :)

Q, why is this on the menu and not just a keyboard shortcut!

Edit -> Select To Brace Matching (brace) Ctrl+4

• Cool :)
• Inside outside matching braces as above, and highlights selection for you :)
  • you still need to explicitly copy to place selection on clipboard
  • X11 copy don't work

NB the above actions also work with "line 7 added [" & "line 13 added ]" hence we are treating brace behind a # comment as active ;-((

Perl -> Find Unmatched Brace (brace)

• Checkes for a lone single brace
• appears to work, but in following code in stead of highlighting }#odd brace not found, highlights my [( $sec on the preceding line.

• Q are we are using more than one algorithm to do brace

Tools -> Preferences -> Behaviour

• the image below shows a composite of the pertinent information.

Auto-complete Brackets

• When checked, if you type an opening brace or String Literal, you get the closing inserted immediately after for you.

Add another closing bracket

• appears to be superfluous
