For the reproducer feature I need to be able to export and import the current LLDB configuration. To realize this I've extended the existing functionality to print settings. With the help of a new formatting option, we can now write the settings and their values to a file structured as regular commands. Concretely the functionality works as follows: (lldb) settings export -f /path/to/file This file contains a bunch of settings set commands, followed by the setting's name and value. ... settings set use-external-editor false settings set use-color true settings set auto-one-line-summaries true settings set auto-indent true ... You can import the settings again by either sourcing the file or using the settings read command. (lldb) settings read -f /path/to/file Differential revision: https://reviews.llvm.org/D52651 llvm-svn: 345346
