QUESTION
I would imagine this is too big and too specific for a normal StackOverflow question, so I can understand if there isn't any possible help. However I will try and show what is the issue I am facing. Also I am new to Perl and I know you shouldn't declare all variables at the start, I'm just trying to see if I can get this implemented first.
I have a Perl script:

does not appear to be a method, but you are calling it as one
QUESTION
so I'm getting this error:
...ANSWER
Answered 2019-Mar-18 at 20:34You're declaring @Z
(using the keyword my
) in two different scopes. One inside the for
loop, and one afterwards. If you need @Z
to still exist after the for
loop completes, you need to declare it outside of (and prior to) that scope.
Also, only use my
once:
QUESTION
Having an issue since don't understand why it's not working for tan, but is fine to work for cos and sin. I would assume the issue is that it's undefined, hence the error message but why exactly does cos and sin work and not tan? How would I then define a tan method? Sorry for the newbie question, I'm just trying to work out Perl.

and cos
are builtin Perl functions, but tan
is not. This is easily remedied with a simple declaration
QUESTION
I have no knowledge of perl, and the open source code I'm looking at it still uses a small element of it. I'm trying to work out if there is anything significant with the words 'honeycomb'? Are they just checking if the variable pattern is equal to the string or am I missing anything?
...ANSWER

Nothing as far as the Perl here is concerned. It is just a string.
Something else will, presumably, read that variable.
Are they just checking if the variable pattern is equal to the string
No. It is an assignment, not a comparison
QUESTION
I'm building a plugin that allows visitors to submit software configurations to share with others. They input several bits of info (their name, the software and the machine) and then upload their XML profile, which is ultimately converted into a custom post type.
As of right now, I am storing everything they input like their name, the software, the machine type, etc. as metadata. I want to have predefined options for software/machine types though, allowing them to choose from these options when submitting.
What would be a good way to achieve this in Wordpress? Should I just keep these as pre-defined values in a select box via the form, then save the data as text in metadata or is there a better alternative?
...ANSWER
Answered 2018-Mar-22 at 07:28If you want to group items together, use a taxonomy. Aside from that being the literal definition of the word, it makes it easy to pull in all posts for the same software and keep those grouped. That's what a Taxonomy excels at.
If you just have a more overall CPT, that just need to have a bit of arbitrary information attached to them, that's what Custom Fields excel at. This is mainly for arbitrary information that's not categorically relatable, like Price
, or Event Start Date
, or Facebook Group/Page URL
.
It sounds like you would be better suited with a taxonomy/term relationship for Software and Machine Type, though ultimately it's up to you. You can query posts based on custom fields, but categorically definable information is better suited for a taxonomy.
As an unrelated aside, is there any particular reason you're using an echo statement per line instead of just closing your PHP tag and echoing the few PHP variables you have inside standard HTML?
QUESTION
I am trying to create a python script that runs a perl script on the Mac terminal. The popular 3D printer slicing engine, Slic3r, has the ability to use command line usage, which is written in Perl. I want to write a python script to automate some processes, which is the language I know best. If I type the commands I want to use directly into the terminal, it works as it should, however, if I try to use python's subprocess
, it works for some commands but not others.
For example if I use my script to fetch the Slic3r version using the syntax outlined in the docs, it works correctly. This script works:
