Re: Including tex commands in a list

[steve-humphreys]

As you pointed out, I misunderstood how to use rx.

However when I applied the change, the keywords are not being
highlighted at all.

  `(;; Greek
    (, (rx "\\" "alpha" (or "beta" "chi") "delta")
     (1 'crucible-mtksy-tfc))
    (,(concat "\\\\\\<\\(Delta\\|epsilon\\|varepsilon\\|eta\\|"
              "gamma\\|Gamma\\|iota\\|kappa \\|"
              "lambda\\|Lambda\\|mu\\|nu\\|"
              "omega\\|Omega\\|phi\\|varphi\\|"
              "Phi\\|pi\\|varpi\\|Pi\\|"
              "psi\\|Psi\\|rho\\|varrho\\|"
              "sigma\\|varsigma\\|Sigma\\|tau\\|"
              "theta\\|vartheta\\|Theta\\|upsilon\\|"
              "Upsilon\\|xi\\|Xi\\|zeta\\)\\>")
     (0 'crucible-mtksy-tfc))
