Help Indented text

[marian <marian@mail.jozep.com.au>]

I have this little patch to give me auto brace completion, which call
should I use to get proper indenting.
I have used the tkTextInsert but this does not give correct nested
indenting.




proc sn_rc_editor {view text} {
    global auto_brace
    global sn_text_highlight_group

    if {$sn_text_highlight_group($text) == "c++"} {
        set auto_brace(for)    {" \( ; ; \) \{\n\t" "\n\}"}
        set auto_brace(if)     {" \( FALSE \) \{\n\t" "\n\}"}
        set auto_brace(else)   {" \{\n\t" "\n\}"}
        set auto_brace(switch) {" \(  \) \{\n\tcase "
":\n\tdefault:\n\}"}
        set auto_brace(while)  {" \(  \) \{\n\t" "\n\}"}
        set auto_brace(do)     {" \{\n\t" "\n\} while \( FALSE \);"}

        # Auto build regexp string
        set names [array names auto_brace]
        set names [ join $names | ]
        set auto_brace(names) $names
        bind  $text <braceleft> {auto_brace %W; break}
    }

    if {$sn_text_highlight_group($text) == "tcl"} {
    }

    proc auto_brace {W} {
        global auto_brace
        global sn_text_highlight_group

        set word [$W get "insert -1 chars wordstart" insert]

        if { [regexp {[$auto_brace(names)]} $word {}] } {

            tkTextInsert $w insert [lindex $auto_brace($word) 0]
            set index [$W index insert]
            tkTextInsert $w insert [lindex $auto_brace($word) 1]

            # Crunch out any trailing elements to make it all a bit
tidier
            set tlist [lrange $auto_brace($word) 2 end]
            foreach element $tlist {
                ac_paste $W $element
            }
            $W mark set insert $index
        }
    }
}
