Command-line YAML/XML processor - jq wrapper for YAML/XML documents
Project description
Installation
pip install yq
Before using yq, you also have to install its dependency, jq. See the jq installation instructions for details and directions specific to your platform.
On macOS, yq is also available on Homebrew: use brew install python-yq.
Synopsis
yq takes YAML input, converts it to JSON, and pipes it to jq:
cat input.yml | yq .foo.bar
Like in jq, you can also specify input filename(s) as arguments:
yq .foo.bar input.yml
By default, no conversion of jq output is done. Use the --yaml-output/-y argument to convert it back into YAML:
cat input.yml | yq -y .foo.bar
Use the --width/-w argument to pass the line wrap width for string literals. All other command line arguments are forwarded to jq. yq forwards the exit code jq produced, unless there was an error in YAML parsing, in which case the exit code is 1. See the jq manual for more details on jq features and options.
YAML tags in the input are ignored (any nested data is treated as untagged). Key order is preserved.
XML support
yq also supports XML. The yq package installs an executable, xq, which transcodes XML to JSON using xmltodict and pipes it to jq. Roundtrip transcoding is available with the xq --xml-output/xq -x option. Multiple XML documents can be passed in separate files/streams as xq a.xml b.xml. Entity expansion and DTD resolution is disabled to avoid XML parsing vulnerabilities.
