New completions: figlet, mdbook, ranger, pygmentize + xz fix

[moverest]

Add figlet, mdbook, ranger and pygmentize and fix xz completions.

[faho]

I believe you didn't want to include this.

[moverest]

Indeed...

[floam]

Totally unrelated, but this thread made me notice that OS X comes with pygments, and pygmentize can highlight fish script by default. Neat.

Nope - something installed it into /usr/bin other than Apple, or pkgutil would show a pkgid here. Nevermind!

pkgutil --file-info /usr/bin/pygmentize
volume: /
path: /usr/bin/pygmentize

[moverest]

I really like this tool. I have defined an alias function cats which does pygmentize -g. It works quite well with fish scripts.

[floam]

fish_indent --ansi highlights better :) But it only does fish.

[moverest]

That's why I use pygmentize. I can throw everything at it without having to think much and the highlights are pretty good. It doesn't even need the extension to guess some languages.

What does figlet -I2 output?

This might be nicer with string, though it's something we can also do later.

/usr/share/figlet/fonts/646-pt.flc
/usr/share/figlet/fonts/ivrit.flf
/usr/share/figlet/fonts/hz.flc
... and some more ...

We only want the name of the fonts (files with the extension .flf or .tlf). Here, that would be:

slant
banner
standard
... and some more ...

[moverest]

This does the same thing:

function __fish_print_figlet_fonts
    set -l lines (find (figlet -I 2) -type f | string match -r '/.*/(.*)\.[ft]lc')

    while set -q lines[2]
        printf '%s\tFont\n' $lines[2]
        set -e lines[1]
        set -e lines[1]
    end
end

[faho]

How about

set -l dir (figlet -I 2)
set -l files $dir/*.flf $dir/*.tlf

printf '%s\tFont\n' (string replace -r '.*/([^/]+)\.[ft]lf' '$1' -- $files)

?

You might want to test the performance here. To do that, define the function, execute it and echo $CMD_DURATION right after. That'll give you the time in milliseconds.

[moverest]

Your solution is much faster (yours: 4ms; sed: 12ms; find + match: 25ms). I'll commit it.

[faho]

So my intuition was correct. The trick, and this applies to all shells, is to use builtins unless you're dealing with large datasets, when specialized tools (GNU's grep is blindlingly fast) might make sense. There's a constant cost to forking off an external command.

[faho]

Merged as ed7bf83..fc3cd77 (I squashed the improvements on top of the original commit).

Thanks!

[moverest]

I have to say that I really like to contribute here. I am always learning something new.
I may have some more in the near future (feh, aria2c).

These commits have been lost somehow from master.

Fixed with 92e3a3c - sorry for the noise.
