This script will convert .json guideline to .rst guideline.
|
|
|
|
Only schema 1.x is supported (guidelines prior to 2018.02 version)
|
|
|
|
This script takes filename (not file path) as argument.
|
|
(File has to be located in interop/guidelines directory)
|
|
|
|
It is possible to specify output directory with --outdir option.
|
|
This option takes path to output directory as argument.
|
|
If this option isn't used file will be stored in interop/doc/source/guidelines
|
|
|
|
Examples:
|
|
|
|
[Generating out.2017.09.rst file to interop/doc/source/guidelines directory]
|
|
python3 jsonToRst.py 2017.09
|
|
|
|
[Generating out.2017.09.rst file to current directory]
|
|
python3 jsonToRst.py 2017.09.json --outdir .
