ansi: speed up escape sequence parsing (#2927) 2 years ago
Junegunn Choi aa10dccf90
Support colon delimiter in ANSI escape sequences 
# Both should work
    printf "\e[38;5;208mOption 1\e[m\nOption 2" | fzf --ansi
    printf "\e[38:5:208mOption 1\e[m\nOption 2" | fzf --ansi

This change makes ANSI parsing slightly slower.

Charlie Vieth 5a874ae241
Speed up ANSI code processing (#2368) 
This commit speeds up the parsing/processing of ANSI escape codes by
roughly 7.5x. The speedup is mostly accomplished by replacing the regex
with dedicated parsing logic (nextAnsiEscapeSequence()) and reducing the
number of allocations in extractColor().

#### Benchmarks
```

Fix #2339

Junegunn Choi 3829eab1cf
Support ANSI code for clearing the rest of the line (ESC[0K) 
Some programs use it to set the background color for the whole line.

  fzf --preview "printf 'normal \x1b[42mgreen\x1b[0K \x1b[43myellow\x1b[m\nnormal again'"

  fzf --preview 'delta <(echo foo) <(echo bar) < /dev/tty'
