| # Converts flat json such as: | |
| # | |
| # .clients[0].id = "59761c23b30d971669fb42ff" | |
| # .clients[0].isActive = true | |
| # .clients[0].age = 36 | |
| # | |
| # back to json. | |
| # The newline in the middle of the sed command is for BSD compatibility | |
| # | |
| # Still one problem: | |
| # - top-level arrays flatten to "[0].asdf" which cause invalid path expressions | |
| # The only hack I can think of right now for this is to wrap top level arrays | |
| # as a value in a pair in the top level object: | |
| # sed -E 's/(^\[[0-9]\])/.TLA\1/g' | |
| # along with the <<< '{"TLA":[]}' listed below instead of <<< '{}' | |
| # | |
| # Doing so would produce the following: | |
| # % echo '["g", 3, "throw"]' | catj | sed -E 's/(^\[[0-9]\])/.TLA\1/g' | uncatj | |
| # { | |
| # "TLA": [ | |
| # "g", | |
| # 3, | |
| # "throw" | |
| # ] | |
| # } | |
| # This ugly change also forces an extra element into normal objects: | |
| # | |
| # % echo '.HostConfig.PortBindings.HostIp = ""' | uncatj | |
| # { | |
| # "TLA": [], | |
| # "HostConfig": { | |
| # "PortBindings": { | |
| # "HostIp": "" | |
| # } | |
| # } | |
| # } | |
| # I hate it but it works | |
