This makes them easy to manage. +The ‘<samp>info pretty-printer</samp>’ command will list all the installed +pretty-printers with their names. +If a pretty-printer can handle multiple data types, then its +<em>subprinters</em> are the printers for the individual data types. +Each such subprinter has its own name. +The format of the name is <var>printer-name</var>;<var>subprinter-name</var>. +</p> +<p>Pretty-printers are installed by <em>registering</em> them with <small>GDB</small>. +Typically they are automatically loaded and registered when the corresponding +debug information is loaded, thus making them available without having to +do anything special. +</p> +<p>There are three places where a pretty-printer can be registered. +</p> +<ul> +<li> Pretty-printers registered globally are available when debugging +all inferiors. + +</li><li> Pretty-printers registered with a program space are available only +when debugging that program. +See <a href="Progspaces-In-Python.html#Progspaces-In-Python">Progspaces In Python</a>, for more details on program spaces in Python. + +</li><li> Pretty-printers registered with an objfile are loaded and unloaded +with the corresponding objfile (e.g., shared library). +See <a href="Objfiles-In-Python.html#Objfiles-In-Python">Objfiles In Python</a>, for more details on objfiles in Python. +</li></ul> + +<p>See <a href="Selecting-Pretty_002dPrinters.html#Selecting-Pretty_002dPrinters">Selecting Pretty-Printers</a>, for further information on how +pretty-printers are selected, +</p> +<p>See <a href="Writing-a-Pretty_002dPrinter.html#Writing-a-Pretty_002dPrinter">Writing a Pretty-Printer</a>, for implementing pretty printers +for new types. +</p> + + + +</body> +</html> |
