If no key exists in the file, get-value gives huge stack trace

[kirhgoff]

To use with big amounts of files I expect shyaml to report empty value for any key, but instead I am getting that:

cat somefile.yml | shyaml get-value abrakadabra Traceback (most recent call last): File "/Users/klastovirya/.pyenv/versions/3.3.6/bin/shyaml", line 308, in aget value = dct[head] KeyError: 'dsfdgfdfgf'

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "/Users/klastovirya/.pyenv/versions/3.3.6/bin/shyaml", line 378, in main value = mget(contents, key_value) File "/Users/klastovirya/.pyenv/versions/3.3.6/bin/shyaml", line 248, in mget return aget(dct, tokenize(key)) File "/Users/klastovirya/.pyenv/versions/3.3.6/bin/shyaml", line 313, in aget % (head, )) main.MissingKeyError During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "/Users/klastovirya/.pyenv/versions/3.3.6/bin/shyaml", line 429, in sys.exit(main(sys.argv[1:])) File "/Users/klastovirya/.pyenv/versions/3.3.6/bin/shyaml", line 385, in main msg = str(exc.message) AttributeError: 'MissingKeyError' object has no attribute 'message'

Thanks for the report. I'll probably implement something in this taste:

• catch all exception, only show the exception's title per default
• use environment variable and/or -d|--debug flag to allow displaying all the exceptions traceback
• Probably untie some very common and expected Exception to give a specially tailored message. The KeyError is one of them I'll have to investiguate., Meanwhile anyone can propose a PR.

Of course, while waiting for that, you can use:

cat somefile.yml | shyaml get-value abrakadabra 2>/dev/null

To get exactly what you wanted. Just in case you didn't know.

I wrote my own gem for my task, just wanted to let you know there is a problem

I just removed the exception that was basically occurring because of a python3 incompatibility. Thanks for your reports, and sorry for the long delay.
