Bug #75867 for JSON: is_xs and is

Subject:

is_xs and is_pp don’t work

I tested this with version 2.53. Both these methods seem to be calling other methods that do not exist: bash-3.2$ perl -Ilib -MJSON -e 'print new JSON->is_pp' Can't locate object method "xs" via package "JSON" at lib/JSON.pm line 198. bash-3.2$ perl -Ilib -MJSON -e 'print new JSON->is_xs' Can't locate object method "module" via package "JSON" at lib/JSON.pm line 193.

Try it; JSON->backend->is_pp; JSON->backend->is_xs;

In that case I think you have a doc bug: ----- So, your program should not depend on the backend module, especially returned objects should not be modified. my $json = JSON->new; # XS or PP? $json->{stash} = 'this is xs object'; # this code may raise an error! To check the backend module, there are some methods - C<backend>, C<is_pp> and C<is_xs>. JSON->backend; # 'JSON::XS' or 'JSON::PP' JSON->backend->is_pp: # 0 or 1 JSON->backend->is_xs: # 1 or 0 $json->is_xs; # 1 or 0 $json->is_pp; # 0 or 1 ----- In the above snippet from JSON.pm’s pod, $json is assigned the result of JSON->new. Then further down you have $json->is_xs and $json->is_pp. But those don‘t work on $json itself.

I had checked old versions and found that your point is right. Object methods is_xs/pp were broken. I fixed it in my repository. https://github.com/makamaka/JSON/ Thank you and sorry for my lazy response. On 2012-3月-19 月 00:36:40, SPROUT wrote: Show quoted text
