A tool used to edit NFD configuration files

This tool is majorly developed for use in NFD integration tests. However, it can also used to edit any INFO-formatted files.

Each invocation of infoedit tool performs exactly one edit and the file is modified in place. To perform multiple edits, infoedit tool should be invoked multiple times on the same file.

Usage

infoedit [-f file] [-s|d|a|r path] [-v value]

OPTIONS:

• -f file: specifies a file to edit
• -s path: specifies a property-tree path to modify
• -v value: used with -s path, sets the value at the path
• -d path: deletes all subtrees matching the path
• -a path: adds a subtree at the path; the subtree is read from stdin
• -r path: replaces a subtree at the path; equivalent to -d path followed by -a path

Sample command lines

./infoedit -f nfd.conf -s general.user -v ndn.user
./infoedit -f nfd.conf -s tables.strategy_choice./site -v /localhost/nfd/strategy/broadcast
./infoedit -f nfd.conf -d tables.strategy_choice./
./infoedit -f nfd.conf -d authorizations
./infoedit -f nfd.conf -a rib.localhost_security <<<EOT
