conninfo-parse is a small and rather niche utility which accepts a PostgreSQL
conninfo (DSN) string,
parses it, and prints the result in one of several formats.
conninfo-parse supports three output formats:
- Delimited — Key/value pairs are printed one pair per line, with each key and value separated by an arbitrary delimiter string. This is the default behaviour; the default delimiter is a tab character.
- JSON — Key/value pairs are printed as members of a JSON object. (Where available.)
- Shell —
Similar to the delimited format, except that key/value pairs are valid shell
variable assignments. This is designed to be used safely with the shell's
evalbuilt-in.
Given how niche this tool is, i feel pretty lazy about the build requirements; i haven't put in any effort to make it extremely portable, &c. As such, you'll need the following to build:
- GCC or Clang
- bash or zsh for
configure - GNU
make pkg-configjson-cheaders (optional — needed for JSON output)libpqheaders
On Debian/Ubuntu you can install the headers via
sudo apt-get install libpq-dev libjson0-dev.
On macOS, brew install postgresql json-c will install the correct headers for
you.
Once you have the necessary prerequisites, simply run ./configure && make to
build.
