How to add `\mathbb` under `'B`?

[maikol-solis]

Hi!

In math, you know the importance of \mathbb to write special sets (R, N, Q, Z, etc.).

I tried to add this to my local configuration, following your code (

LaTeX-auto-activating-snippets/laas.el

Lines 421 to 435 in a00f0ab

	(defun laas-accent--rm () (interactive) (laas-wrap-previous-object (if (laas-mathp) "mathrm" "textrm")))
	(defun laas-accent--it () (interactive) (laas-wrap-previous-object (if (laas-mathp) "mathit" "textit")))
	(defun laas-accent--bf () (interactive) (laas-wrap-previous-object (if (laas-mathp) "mathbf" "textbf")))
	(defun laas-accent--emph () (interactive) (laas-wrap-previous-object (if (laas-mathp) "mathem" "emph")))
	(defun laas-accent--tt () (interactive) (laas-wrap-previous-object (if (laas-mathp) "mathtt" "texttt")))
	(defun laas-accent--sf () (interactive) (laas-wrap-previous-object (if (laas-mathp) "mathsf" "textsf")))
	(defvar laas-accent-snippets
	`(;; work in both normal latex text and math
	:cond laas-latex-accent-cond
	:expansion-desc "Wrap in \\mathrm{} or \\textrm{}" "'r" laas-accent--rm
	:expansion-desc "Wrap in \\mathit{} or \\textit{}" "'i" laas-accent--it
	:expansion-desc "Wrap in \\mathbf{} or \\textbf{}" "'b" laas-accent--bf
	:expansion-desc "Wrap in \\mathemph{} or \\textemph{}" "'e" laas-accent--emph
	:expansion-desc "Wrap in \\mathtt{} or \\texttt{}" "'y" laas-accent--tt
	:expansion-desc "Wrap in \\mathsf{} or \\textsf{}" "'f" laas-accent--sf

).

But, I failed miserably. This is what I have:

  (defun laas-accent--bb ()
    (interactive)
    (laas-wrap-previous-object (if (laas-mathp) "mathbb" "")))
  (aas-set-snippets 'laas-mode
    :cond #'laas-latex-accent-cond
    :expansion-desc "Wrap in \\mathbb{}"
    "B" #'laas-accent--bb))

I don't know if you could give me some pointers about what I am missing, or even better, see if this could be implemented in the package itself.

In any case, thanks for your assistance.

Best.

I could make some progress defining this snippet

(aas-set-snippets 'laas-mode
    :cond #'laas-object-on-left-condition
    :expansion-desc "Wrap in \\mathbb{}"
    "bb" #'laas-accent--bb)

So you need to type $Rbb$ to turn it into $\mathbb{R}$.

It isn't like the others, but it works well enough.

For reference , "Rbb" --> "\mathbb{R}" can be added to configuration by the same idea as "qq" value in the example. Adding this line

"bb" (lambda () (interactive) (laas-wrap-previous-object "mathbb")))

after "qq" entry should work.
