Some math expressions are spelled in LaTeX whereas they should not be

[bartosz-antosik]

James Yu suggested in one of comments to issue #225 that Spell Right spells math expressions like:

\forall(i,j)\notin\mathcal{E}

where i gets underlined as spelled incorrectly (suggesting capital).

They should not be spelled.

Correct me if I am wrong, but it seems to me that this expression would get spelled only outside of math braces ($ and $ etc.), where it should not exist in this form. I assumed that only \command{...}... and \command[..]... should not be spelled in normal document context and nothing inside math braces.

In fact, in LaTeX it is very common to have math equations in the following form:

\begin{align}
\some_{equations}^{here}
\end{align}

The snippet I provided was also surrounded by the environment. The way cSpell handles this problem is simply ignore any words with three or less letters, which I found to be surprisingly effective and not causing many false negatives. Just for your reference.

You are right. The expression will be eliminated by modified regexp. Next release will have it.

About spelling starting from some length of the word, e.g. 4 characters. I am very strong against about spelling starting from some length! This was in fact my objection against most of the spell checkers I have examined before starting mine on the beginning of this year. It makes impossible to spell a lot of short words, shortcuts and abbreviations (I'm, etc., i.e. etc., etc.) As I was stressing my intention was to produce a precise speller thus a lot of tweaking in the parsers.
