in reply to Oneliner with substring trimming and padding

What about the following approach:

  1. adding a "maximum number" of padding-characters at the end of your substring
  2. cutting the substing back to the desired number of characters
That way you avoid calculating the real number of needed padding-characters

Just an idea. Rata

    Sure, but how do you do this in an inplace-edit oneliner? :)

[moritz]: choroba in python I use jsonschema
[moritz]: I'm sure there's a Perl implementation of it too
[choroba]: it seems Kelp and similar help you a lot with dispatching, but how to do something similar with contents?
[moritz]: like JSON::Schema
[Corion]: ambrus++ # more bugs than lines
[Corion]: That's like "works on my machine" ;-)
[choroba]: I mean, I'd like to say "this path should run this sub, but first it should check the user is authenticated, has the following permissions, and the contents is valid against a given schema
[ambrus]: no, that means I haven't even tried to run it, might not even parse
[ambrus]: so it doesn't work on my machine
[choroba]: i.e. I know JSON::Schema, I'm just curious whether there's a ready solution to plug it into a web service
