10 ==============================================================================
11 1. Using Unicode in your Raku files *raku-unicode*
12
13 Defining new operators using Unicode symbols is a good way to make your
14 Raku program easy to read. See:
15 https://perl6advent.wordpress.com/2012/12/18/day-18-formulas-resistance-is-futile/
16
17 While Raku does define ASCII alternatives for some common operators (see
18 https://docs.raku.org/language/unicode_ascii), using the full range of
19 Unicode operators is highly desirable. Your operating system provides input
20 facilities, but using the features built in to Vim may be preferable.
21
22 The natural way to produce these symbols in Vim is to use digraph shortcuts
23 (:help |digraphs-use|). Many of them are defined; type `:digraphs` to get
24 the list. A convenient way to read the list of digraphs is to save them in a
25 file. From the shell: >
26 vim +'redir >/tmp/vim-digraphs-listing.txt' +digraphs +'redir END' +q
27
28 Some of them are available with standard Vim digraphs:
29 << « /0 ∅ !< ≮ ~
30 >> » Ob ∘ !> ≯ ~
31 ., … 00 ∞ (C ⊂ ~
32 (U ∩ -: ÷ )C ⊃ ~
33 )U ∪ (_ ⊆ >= ≥ ~
34 ?= ≅ )_ ⊇ =< ≤ ~
35 (- ∈ ?= ≅ != ≠ ~
36 -) ∋ ?- ≃ ~
37
38 The Greek alphabet is available with '*' followed by a similar Latin symbol:
39 *p π ~
40 *t τ ~
41 *X × ~
42
43 Numbers, subscripts and superscripts are available with 's' and 'S':
44 0s ₀ 0S ⁰ ~
45 1s ₁ 1S ¹ ~
46 2s ₂ 9S ⁹ ~
47
48 But some don´t come defined by default. Those are digraph definitions you can
49 add in your ~/.vimrc file. >

61 exec 'digraph ne '.char2nr('𝑒')
62 " Raku's atomic operations marker
63 exec 'digraph @@ '.char2nr('⚛')

65 Alternatively, you can write Insert mode abbreviations that convert ASCII-
66 based operators into their single-character Unicode equivalent. >
