gdb: Guile Auto-loading
23.3.4 Guile Auto-loading
-------------------------
When a new object file is read (for example, due to the 'file' command,
or because the inferior has loaded a shared library), GDB will look for
Guile support scripts in two ways: 'OBJFILE-gdb.scm' and the
'.debug_gdb_scripts' section. Auto-loading extensions.
The auto-loading feature is useful for supplying application-specific
debugging commands and scripts.
Auto-loading can be enabled or disabled, and the list of auto-loaded
scripts can be printed.
'set auto-load guile-scripts [on|off]'
Enable or disable the auto-loading of Guile scripts.
'show auto-load guile-scripts'
Show whether auto-loading of Guile scripts is enabled or disabled.
'info auto-load guile-scripts [REGEXP]'
Print the list of all Guile scripts that GDB auto-loaded.
Also printed is the list of Guile scripts that were mentioned in
the '.debug_gdb_scripts' section and were not found. This is
useful because their names are not printed when GDB tries to load
them and fails. There may be many of them, and printing an error
message for each one is problematic.
If REGEXP is supplied only Guile scripts with matching names are
printed.
Example:
(gdb) info auto-load guile-scripts
Loaded Script
Yes scm-section-script.scm
full name: /tmp/scm-section-script.scm
No my-foo-pretty-printers.scm
When reading an auto-loaded file, GDB sets the "current objfile".
This is available via the 'current-objfile' procedure (Objfiles In
Guile). This can be useful for registering objfile-specific
pretty-printers.
