TypeError: [Line: 0, Offset 5] Malformed argument.

[xthyax]

Hi, First of all, thanks for your tools.

I just stumble on this issue(maybe a potential bug), I can't find any solution for it, and I really need help on this.

My input:

'\\frac{ \\left(2^{6} \\cdot 5.7\\right)\\left(5^{4} \\cdot 7^{9}\\right)}{\\left(2.5 .7^{2}\\right)^{5}}'

My code:

from TexSoup import TexSoup
TexSoup('\\frac{ \\left(2^{6} \\cdot 5.7\\right)\\left(5^{4} \\cdot 7^{9}\\right)}{\\left(2.5 .7^{2}\\right)^{5}}')

My error:

TypeError: [Line: 0, Offset 5] Malformed argument. First and last elements must match a valid argument format. In this case, TexSoup could not find matching punctuation for: {.
Just finished parsing: ['{', ' ', TexCmd('left(2'), '^', BraceGroup('6'), ' ', TexCmd('cdot'), ' 5.7', TexCmd('right)'), 'left(5', '^', BraceGroup('4'), ' ', TexCmd('cdot'), ' 7^', BraceGroup('9'), TexCmd('right)}', [BraceGroup(TexCmd('left(2'), '.5 .7^', BraceGroup('2'), TexCmd('right)^', [BraceGroup('5')]))])]

I'm using

TexSoup 0.3.1
Python 3.8.13

Thank you!

I think I find the problem

When this is fine

TexSoup('\\frac{\\right) }{}')

But this will lead to an error

TexSoup('\\frac{\\right)}{}')

The error will be like this:

TypeError: [Line: 0, Offset 5] Malformed argument. First and last elements must match a valid argument format. In this case, TexSoup could not find matching punctuation for: {.
Just finished parsing: ['{', TexCmd('right)}', [BraceGroup()])]

Since this's a bug, but needs to work around for it to work, I'll leave it open
