I am wondering if there is a simple way to expand some input text such as "3-7" as "3,4,5,6,7"?
For context, I am using foreach and want to be able to write
foreach x in 3-7, 9, 14, 52
and have x run through 3, 4, 5, 6, 7, 9, 14, and 52.
Alternatively, if there's an easy way to have
foreach x in 1,3,...7
result in x being defined as "1, 3, 4, 5, 6, and 7" instead of the standard "1, 3, 5, and 7", that would be great.
EDIT: I don't think I was clear in my explanation, but I personally understand how to do these foreach commands in TeX, but wanted a simple input structure for a non-TeX user to use, i.e. typing makeProblems1, 3-7, 9, 14, 52 and having the associated problems as output.

With a little bit of code you can make yourself a parser. I defined makeProblems<integer list><code> for you, in which <integer list> is a comma separated list of numbers where <x>-<y> is parsed as the list of integers between <x> and <y>, inclusive. The function parses the list of numbers and then iterates over the generated list, and makes the current number available for <code> as #1. For example:
makeProblems1,3-7, 9, 14, 52Do something with #1.par
prints:
The code is long because, as the function takes user input, the function takes extra care to make sure that the <integer list> doesn't contain wrong input.

I map the given comma separated list; each item is examined and if it contains a hyphen, a loop is done; in any case, an integer is added to a sequence.
Finally the sequence is expanded with separators between the items; optionally this token list is saved to a macro.

@ryanj1823 You probably have some older version of thel3kernel. Could you upload the.logfile somewhere for me to check? (pastebin.com, for example.)

@ryanj1823 Try it now. There were twoexpl3functions which don't exist in your distribution (TeXLive 2017), so I adapted the code. (I can't test, though, so tell me if it doesn't work.)

@ryanj1823 Done. Now the command expands its argument before processing. Of course you can alwaysexpandaftermakeProblemsexpandafterDesiredProblems, but I think that's not exactly user-friendly.

With a little bit of code you can make yourself a parser. I defined makeProblems<integer list><code> for you, in which <integer list> is a comma separated list of numbers where <x>-<y> is parsed as the list of integers between <x> and <y>, inclusive. The function parses the list of numbers and then iterates over the generated list, and makes the current number available for <code> as #1. For example:
makeProblems1,3-7, 9, 14, 52Do something with #1.par
prints:
The code is long because, as the function takes user input, the function takes extra care to make sure that the <integer list> doesn't contain wrong input.

I map the given comma separated list; each item is examined and if it contains a hyphen, a loop is done; in any case, an integer is added to a sequence.
Finally the sequence is expanded with separators between the items; optionally this token list is saved to a macro.

Did you try
foreach x in 1,3,4,...,7?– Phelype Oleinik
8 hours ago
I've thought about that, but wanted the input structure to
foreachto be as simple as possible to a non-TeX user. The user (not familiar with TeX), will call a commandmakeProblems1, 3,...,7(where the input is thrown intoforeach) and expect everything between 3 through 7 to output.– ryanj1823

foreach x in 3,...,7, 9, 14, 52andforeach x in 1,3,4,5,...,7?– marmot

To the first command: I understand that that works, but I wanted to avoid using the dots altogether if possible. To the second command: see my reply above to Pheylpe Oleinik
