Shyaml: Process YAML in the command line

Shyaml: Process YAML in the command line

YAML is a friendly data exchange format for humans. If you need to process YAML in the Linux Command Line, use shyaml.

Through shyaml, you can directly obtain the key, value, key-value pair, or corresponding type. To install shyaml, run the following command:

pip install shyaml

Because shyaml reads YAML content from the standard input and prints the result to the standard output, its common usage is:

cat <file.yaml> | shyaml ACTION KEY [DEFAULT]

HereACTIONIt can be:

• get-type: Get the corresponding type
• get-value: Get value
• get-values{,-0}: For the sequence type, obtain the Value List
• keys{,-0}: Return key list
• values{,-0}: Return Value List
• key-values,{,-0}: Return key-value pairs

The result is added by default.\nLine Break. If-0The format isNULCharacter filling.

KEYIs the Key to be queried. If not, useDEFAULT.

For example, the content of our file. yaml file is:

---idc_group:  name: bx  bx:     news_bx: news_bx    web3_bx: web3_php-fpm_bx

If you want to obtainidc_group.nameCan be executed:

cat file.yaml | shyaml get-value idc_group.name

Want to getidc_group.bxCan be executed:

cat file.yaml | shyaml key-values idc_group.bx

If you want to process JSON data in the Linux Command Line, I strongly recommend jq as a useful tool.
