For +example, <code>print -pretty</code>. Similarly to command names, you can +abbreviate a <small>GDB</small> option to the first few letters of the +option name, if that abbreviation is unambiguous, and you can also use +the <tt class="key">TAB</tt> key to get <small>GDB</small> to fill out the rest of a word +in an option (or to show you the alternatives available, if there is +more than one possibility). +</p> +<a name="index-command-options_002c-raw-input"></a> +<p>Some commands take raw input as argument. For example, the print +command processes arbitrary expressions in any of the languages +supported by <small>GDB</small>. With such commands, because raw input may +start with a leading dash that would be confused with an option or any +of its abbreviations, e.g. <code>print -p</code> (short for <code>print +-pretty</code> or printing negative <code>p</code>?), if you specify any command +option, then you must use a double-dash (<code>--</code>) delimiter to +indicate the end of options. +</p> +<a name="index-command-options_002c-boolean"></a> + +<p>Some options are described as accepting an argument which can be +either <code>on</code> or <code>off</code>. These are known as <em>boolean +options</em>. Similarly to boolean settings commands—<code>on</code> and +<code>off</code> are the typical values, but any of <code>1</code>, <code>yes</code> and +<code>enable</code> can also be used as “true” value, and any of <code>0</code>, +<code>no</code> and <code>disable</code> can also be used as “false” value. You +can also omit a “true” value, as it is implied by default. +</p> +<p>For example, these are equivalent: +</p> +<div class="smallexample"> +<pre class="smallexample">(gdb) print -object on -pretty off -element unlimited -- *myptr +(gdb) p -o -p 0 -e u -- *myptr +</pre></div> + +<p>You can discover the set of options some command accepts by completing +on <code>-</code> after the command name. For example: +</p> +<div class="smallexample"> +<pre class="smallexample">(gdb) print -<span class="key">TAB</span><span class="key">TAB</span> +-address -max-depth -object -static-members +-array -memory-tag-violations -pretty -symbol +-array-indexes -nibbles -raw-values -union +-elements -null-stop -repeats -vtbl +</pre></div> + +<p>Completion will in some cases guide you with a suggestion of what kind +of argument an option expects. For example: +</p> +<div class="smallexample"> +<pre class="smallexample">(gdb) print -elements <span class="key">TAB</span><span class="key">TAB</span> +NUMBER unlimited +</pre></div> + +<p>Here, the option expects a number (e.g., <code>100</code>), not literal +<code>NUMBER</code>. Such metasyntactical arguments are always presented in +uppercase. +</p> +<p>(For more on using the <code>print</code> command, see <a href="Data.html#Data">Examining +Data</a>.) +</p> +<hr> +<div class="header"> +<p> +Next: <a href="Help.html#Help" accesskey="n" rel="next">Help</a>, Previous: <a href="Completion.html#Completion" accesskey="p" rel="previous">Completion</a>, Up: <a href="Commands.html#Commands" accesskey="u" rel="up">Commands</a> [<a href="index.html#SEC_Contents" title="Table of contents" rel="contents">Contents</a>][<a href="Concept-Index.html#Concept-Index" title="Index" rel="index">Index</a>]</p> +</div> + + + +</body> +</html> |
