Passing values through a variable

[michael-franzese]

I want to change the expression (1 'texcmd-colour) so that
the value 1 can be set through a variable (e.g. stdhl).

Can I just do

(defvar-local stdhl 1
  "Uses standard highlighting for keywords when set to 1.
When stdhl is 0, the leading backslash is also highlighted.")

(defconst tex-keywords
  `(
    ;; Greek.  Use (0 'texcmd-colour) to highlight the leading "\".
    (,(rx "\\" word-start (group (or "alpha" "beta" "chi" "delta"
          "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")) word-end)
     (stdhl 'texcmd-colour))

(font-lock-add-keywords nil comseq-crucible t)


Below is the original code

(defconst tex-keywords
  `(
    ;; Greek.  Use (0 'colour-tex-cruc) to highlight the leading "\".
    (,(rx "\\" word-start (group (or "alpha" "beta" "chi" "delta"
          "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")) word-end)
     (1 'texcmd-colour))

(font-lock-add-keywords nil tex-keywords t)
