LaTeX Auto Activating Snippets

A chunky set of LaTeX snippets for the auto-activating-snippets engine.

Sample Configuration

(use-package laas
  :hook (LaTeX-mode . laas-mode)
  :config ; do whatever here
  (aas-set-snippets 'laas-mode
                    ;; set condition!
                    :cond #'texmathp ; expand only while in math
                    "supp" "\\supp"
                    "On" "O(n)"
                    "O1" "O(1)"
                    "Olog" "O(\\log n)"
                    "Olon" "O(n \\log n)"
                    ;; bind to functions!
                    "Sum" (lambda () (interactive)
                            (yas-expand-snippet "\\sum_{$1}^{$2} $0"))
                    "Span" (lambda () (interactive)
                             (yas-expand-snippet "\\Span($1)$0"))
                    ;; add accent snippets
                    :cond #'laas-object-on-left-condition
                    "qq" (lambda () (interactive) (laas-wrap-previous-object "sqrt"))))

Annoying Subscripts

Automatic subscripts! Expand In math and after a single letter.

ii	X_i, or XYi if a subscript was typed already
ip1	i+1
jj	X_j, or XYj if a subscript was typed already
jp1	j+1
nn	X_n, or XYn if a subscript was typed already
np1	n+1
kk	X_k, or XYk if a subscript was typed already
kp1	k+1
0	X_0, or XY0 if a subscript was typed already
1	X_1, or XY1 if a subscript was typed already
2	X_2, or XY2 if a subscript was typed already
3	X_3, or XY3 if a subscript was typed already
4	X_4, or XY4 if a subscript was typed already
5	X_5, or XY5 if a subscript was typed already
6	X_6, or XY6 if a subscript was typed already
7	X_7, or XY7 if a subscript was typed already
8	X_8, or XY8 if a subscript was typed already
9	X_9, or XY9 if a subscript was typed already

The infamous fraction

Frac snippet.
Expand to a template frac after //, or wrap the object before point if it isn~t /.

:

ab/ => \frac{ab}{}
// => \frac{}{}

/	See the docs of `laas-frac-snippet’

Simpler Accents

A simpler way to apply accents. Expand If LaTeX symbol immidiately before point.
