The documentation say that the display_hint method must return a string to serve as a display hint, and then goes on to list some acceptable strings. However, if we don't supply the display_hint method then we get a default display style behaviour and there's currently no way (in the python api) to force this default behaviour. The guile api allows #f to be used in order to force the default display style behaviour, and this is documented. Currently, using None in the python api also forces the default display behaviour. This commit extends the documentation to make returning None from the display_hint method an official mechanism by which the user can get the default display style. I've extended one of the existing tests to cover this case. gdb/doc/ChangeLog: * python.texi (Pretty Printing API): Document use of None for the display_hint. gdb/testsuite/ChangeLog: * gdb.python/py-prettyprint.c (struct container) <is_map_p>: New field. (make_container): Initialise new field. * gdb.python/py-prettyprint.exp: Add new tests. * gdb.python/py-prettyprint.py (class ContainerPrinter) <display_hint>: New method.
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
