This is code to be reused by json2yaml.
The help text now looks like this:
Reads a JSON document and writes it out as YAML document.
Usage: json2yaml [IN] [OUT]
Available options:
-h,--help Show this help text
-V,--version Show version info.
--numeric-version Show just version number.
IN The input file containing the JSON document; use '-'
for stdin.
OUT The file to hold the produced YAML document; use '-'
for stdout.
Only semantic change: use `die` instead of `error`, so the error
json2yaml: Invalid input JSON
CallStack (from HasCallStack):
error, called at exe/json2yaml.hs:19:20 in main:Main
is now just
json2yaml: Invalid input JSON
… yaml2json These executables haven't been mentioned in README so far.
