22.3.4.3 Tilde W: Write</H2> <P>
|
|
An argument, any <A REL=DEFINITION HREF="26_glo_o.htm#object"><I>object</I></A>, is printed obeying every printer control variable (as by <A REL=DEFINITION HREF="f_wr_pr.htm#write"><B>write</B></A>). In addition, <TT>~W</TT> interacts correctly with depth abbreviation, by not resetting the depth counter to zero. <TT>~W</TT> does not accept parameters. If given the <A REL=DEFINITION HREF="26_glo_c.htm#colon"><I>colon</I></A> modifier, <TT>~W</TT> binds <A REL=DEFINITION HREF="v_pr_pre.htm#STprint-prettyST"><B>*print-pretty*</B></A> to <A REL=DEFINITION HREF="26_glo_t.htm#true"><I>true</I></A>. If given the <A REL=DEFINITION HREF="26_glo_a.htm#at-sign"><I>at-sign</I></A> modifier, <TT>~W</TT> binds <A REL=DEFINITION HREF="v_pr_lev.htm#STprint-levelST"><B>*print-level*</B></A> and <A REL=DEFINITION HREF="v_pr_lev.htm#STprint-lengthST"><B>*print-length*</B></A> to <A REL=DEFINITION HREF="a_nil.htm#nil"><B>nil</B></A>. <P>
|

<TT>~W</TT> provides automatic support for the detection of circularity and sharing. If the <A REL=DEFINITION HREF="26_glo_v.htm#value"><I>value</I></A> of <A REL=DEFINITION HREF="v_pr_cir.htm#STprint-circleST"><B>*print-circle*</B></A> is not <A REL=DEFINITION HREF="a_nil.htm#nil"><B>nil</B></A> and <TT>~W</TT> is applied to an argument that is a circular (or shared) reference, an appropriate <TT>#</TT><I>n</I><TT>#</TT> marker is inserted in the output instead of printing the argument. <P>
