  66. <p>When a new object file is read (for example, due to the <code>file</code>
  67. command, or because the inferior has loaded a shared library),
  68. <small>GDB</small> will look for Guile support scripts in two ways:
  69. <samp><var>objfile</var>-gdb.scm</samp> and the <code>.debug_gdb_scripts</code> section.
  70. See <a href="Auto_002dloading-extensions.html#Auto_002dloading-extensions">Auto-loading extensions</a>.
  71. </p>
  72. <p>The auto-loading feature is useful for supplying application-specific
  73. debugging commands and scripts.
  74. </p>
  75. <p>Auto-loading can be enabled or disabled,
  76. and the list of auto-loaded scripts can be printed.
  77. </p>

  93. <dd><p>Print the list of all Guile scripts that <small>GDB</small> auto-loaded.
  94. </p>
  95. <p>Also printed is the list of Guile scripts that were mentioned in
  96. the <code>.debug_gdb_scripts</code> section and were not found.
  97. This is useful because their names are not printed when <small>GDB</small>
  98. tries to load them and fails. There may be many of them, and printing
  99. an error message for each one is problematic.
  100. </p>
  101. <p>If <var>regexp</var> is supplied only Guile scripts with matching names are printed.
  102. </p>
  103. <p>Example:

  105. <div class="smallexample">
  106. <pre class="smallexample">(gdb) info auto-load guile-scripts
  107. Loaded Script
  108. Yes scm-section-script.scm

  110. No my-foo-pretty-printers.scm
  111. </pre></div>
  112. </dd>
  113. </dl>
  114. <p>When reading an auto-loaded file, <small>GDB</small> sets the
  115. <em>current objfile</em>. This is available via the <code>current-objfile</code>
  116. procedure (see <a href="Objfiles-In-Guile.html#Objfiles-In-Guile">Objfiles In Guile</a>). This can be useful for
  117. registering objfile-specific pretty-printers.
