How to prevent string truncation in debugger's Variables window? [message #1433307]

When debugging C/C++ code in Eclipse CDT (Linux), in the debugger's Variables window only a part of the string's contents is shown for strings which are longer than 1024 characters or so. Right-clicking on the window and selecting "Max length..." with setting the max. length to big values or to 0 - doesn't change anything. Currently the only ways I know to see the whole string is via memory view or via "Display as array" menu item, but this is inconvenient. Is there a way to show the required length of string in the debugger's 'Variables' window?

Did you limit the displayed lengh in your gdbinit file? AFAIK, the option "set print elements MAXLENGTH" would limit the output from gdb. It is also possible that the output length is limited by the pretty printer python script if you are using e.g. std::string.

Alex,

There is no .gdbinit file on my computer. Does gdb have some displayed length limit by default? Or does Eclipse set this limit to gdb somewhere elese than in .gdbinit file? Is it by design that Eclipse out of the box truncates strings in debugger?
