Roman Numeral workflow keeps telling "Invalid Numeral".

 

[zeitlings]

🤷‍♂️

What is the debugger saying?

 

FYI, this forum is intended for general bug reports related to the Alfred App.

A better place report your issue would be the thread for the workflow:

Moved the thread to the right place.

 

@Cipri For future reports, please be sure to consult the short guide on asking for help with a workflow.

Mysterious indeed. Have you tried reinstalling the workflow? Are you running macOS 13 or newer? I assume so, because there are no complaints about the Regex.

The "Invalid Numeral" response is shown when the input is identified as not-a-number, i.e. casting "2" and "20" to an integer fails, which is nonsensical.

 

[Cipri]

I have reinstalled the workflow, it didn't work. I´m running Sequoia. 

[zeitlings]

Since we have nothing to go by, I simply changed some implementation details: avoid direct ScriptFilter input, launch with explicit regex support, and compile, which might at least yield an error. -> Roman Numeral v1.2.0.

[Cipri]

Version 1.2.0 works! Thank you.

[olivergiangvu]

Is the limit is up to 10,000? Any number beyond that take me to a Invalid Number.

Glad to hear it, although I can't say why.

By convention, the limit is 3999.

The Roman numeral system technically doesn’t “stop” at 3,999, but the way it is typically written does. Roman numerals are additive and subtractive symbols, with values such as I (1), V (5), X (10), and so on. The largest commonly used symbol is M (1,000).

 

To represent numbers larger than 3,999, Romans used a convention where a bar was placed over a numeral to multiply its value by 1,000. For example:

 

• V̅ = 5,000

• X̅ = 10,000

• L̅ = 50,000

 

However, in most modern applications of Roman numerals, especially in things like clock faces or movie credits, numbers beyond 3,999 are rare, so the bar-over convention isn’t commonly used.

 

Since the standard Roman numeral system does not have standalone symbols for values above M (1,000) and doesn’t easily represent more complex numbers, it’s often said to “stop” at 3,999 (MMMCMXCIX), the largest number that can be written with the commonly used Roman numerals.

Alfred version: Alfred 5.5.1 Build 2273

MacOS version: Sequoia 15.1.1 

Version 1.2.0 is not functioning as expected. When entering the keyword "rn" along with a value, no output is produced. Interestingly, downgrading to version 1.1.0 resolves the issue, and it works correctly.

 

Here is the debug result with version 1.2.0: 

[20:30:38.728] Roman Numeral[Script Filter] Queuing argument '3'
[20:30:45.325] Roman Numeral[Script Filter] Queuing argument '3'
[20:30:46.683] Roman Numeral[Script Filter] Queuing argument '1'
[20:30:49.372] Roman Numeral[Script Filter] Queuing argument '7'
[20:30:49.427] Roman Numeral[Script Filter] Queuing argument '70'
[20:30:49.934] Roman Numeral[Script Filter] Queuing argument '7'

 

 

 

 

And here is the debug result with version 1.1.0:

[20:44:46.346] Roman Numeral[Script Filter] Queuing argument '3'
[20:44:47.110] Roman Numeral[Script Filter] Script with argv '3' finished
[20:44:47.115] Roman Numeral[Script Filter] {"items":[{"title":"III","arg":"III","text":{"copy":"III","largetype":"III"},"valid":true}]}

Hey @David H

 

¯\_(ツ)_/¯. Thanks for reporting though.

 

v1.2.1 implements some preemptive workarounds for pitfalls that worked in other contexts.

 

• Added some debug logging
• Added preemptive known pitfall workarounds
• Compiles without optimizations to preserve debug information
• Switched to xcrun swiftc

Thank you for updating it! However, v1.2.1 is still not working. So I'm still using v1.1.0.

I experienced the same result as with v1.2.0.

I'd be of course interested in the logs of v1.2.1.

 

The script makes some comments before accessing the Swift file, which you should be able to see.
Something like this:

 

[18:01:46.799] Roman Numeral[Script Filter] Queuing argument '2'
[18:01:47.813] Roman Numeral[Script Filter] Script with argv '2' finished

They were the logs of v1.2.1, which was the same as with v1.2.0.

 

 

I reinstalled v.1.1.0, which works, and here are the logs:
