Latex syntax misclassified

[DavidNC]

Hi

I am experimenting with sublime text 3 as a replacement for Emacs. I primarily use it to write academic papers in Latex. I noticed that my latex code is not color coded properly. In particular, within a math environment (inline or displayed) some of my greek letters are not colored the same as the others. After investigating it further, I noticed that some (such as \tau, \iota, \zeta, \eta, \theta, and \lambda) are categorized as “text.tex.latex meta.environment.math.block.be.latex meta.group.brace.latex support.function.math.tex” while the others (such as \rho ) are categorized as “text.tex.latex meta.environment.math.block.be.latex meta.group.brace.latex keyword.other.greek.math.tex”. I have also noticed that for those that are categorized as “support.function.math.tex” if I enclose them in a pair of parentheses, they will be categorized as “keyword.other.greek.math.tex”. (The greeks that are misclassified are often, but not always, followed by a subscript “_”, so the problem could be in the regular expression used to define these scopes).

It seems there is a bug somewhere in the latex.sublime-syntax file. Is there any fix for it?

Thanks,

What build of Sublime Text are you using? Build 3140 (from https://www.sublimetext.com/3dev) has some LaTeX bug fixes beyond what build 3126 has.

The syntax is developed in the open at https://github.com/sublimehq/Packages/tree/master/LaTeX. Bugs against the latest version can be reported at https://github.com/sublimehq/Packages/issues.

All have the syntax text.tex.latex meta.environment.math.block.be.latex keyword.other.greek.math.tex in my setup. Have you edited your syntax or use some syntax adaption (e.g. from LaTeXing)? Open the ST console ctrl+` and paste view.settings().get("syntax") this should print 'Packages/LaTeX/LaTeX.sublime-syntax'.

Hi wbond and r-stein

Thank you for following up. My Sublime Text build is 3126. I have not edited any syntax file. I just use what it is coming with Sublime Text with LatexTools and other Latex recommended packages (those that are recommend by LatexTools) installed. After experimenting further, I noticed that the problem only occurs if the greek symbol is followed by a subscript. For example $\lambda_t$ or $\eta_i$. I will report the issue on the github page wbond recommended.

Thanks,

Hi r-stein

I am getting those scopes by following the instruction I found here: https://www.sublimetext.com/docs/3/syntax.html. (here is the relevant part: “While editing in Sublime Text, you can check what scopes have been applied to the text under the caret by pressing control+shift+p (OSX) or ctrl+alt+shift+p (Windows and Linux).”) I do not have LaTeXing package installed, and have not edited any syntax file.

Thanks,

It seems this has been fixed in the latest builds in this commit, it will be fixed after the next Sublime Text update and no need to create an issue .

Great. Thanks!
