a string's length in characters

hint · spec 14-cli

A note of lyric fix --from-4: a string's length() counted characters in Lyric 4 and counts bytes in Lyric 5; the migration writes charCount().

Explanation

Lyric 4's s.length() counted code points, in O(n); Lyric 5's counts bytes, in O(1), and charCount() counts what Lyric 4 counted. The migration writes charCount() everywhere, so the program counts as it did, and says so once a module.

Where bytes are what is meant — beside a slice s[a..b] or an index from find, which count bytes — write length(): it is faster, and it is what those positions count in.

Example

proposal[LYR-MIG0312] main.lyr:7:16: a string's 'length()' counted characters in Lyric 4 and counts bytes in Lyric 5; the migration writes 'charCount()', which counts what it counted, in O(n) — where bytes are what is meant, as beside a slice or a 'find', write 'length()'
