<B>lsearch </B>?<I>mode</I>? <I>list pattern</I><BR>

<H3><A NAME="M4">DESCRIPTION</A></H3>
|
|
This command searches the elements of <I>list</I> to see if one
|
|
of them matches <I>pattern</I>.
|
|
If so, the command returns the index of the first matching
|
|
element.
|
|
If not, the command returns <B>-1</B>.
|
|
The <I>mode</I> argument indicates how the elements of the list are to
|
|
be matched against <I>pattern</I> and it must have one of the following
|
|
values:
|
|
<P>
|
|
<DL>
|
|
<P><DT><A NAME="M5"><B>-exact</B></A><DD>
|
|
The list element must contain exactly the same string as <I>pattern</I>.
|
|
<P><DT><A NAME="M6"><B>-glob</B></A><DD>
|
|
<I>Pattern</I> is a glob-style pattern which is matched against each list
|
|
element using the same rules as the <B><A HREF="../TkCmd/string.htm">string match</A></B> command.
|
|
<P><DT><A NAME="M7"><B>-regexp</B></A><DD>
|
|
<I>Pattern</I> is treated as a regular expression and matched against
|
|
each list element using the rules described in the <B><A HREF="../TkCmd/re_syntax.htm">re_syntax</A></B>
|
|
reference page.
|
|
<P></DL>
|
|
<P>
|
|
If <I>mode</I> is omitted then it defaults to <B>-glob</B>.
