NOTICE Option declaration syntax changed from $*foo to $:foo

Implemented List index accessors

my @a = <zero one two three>;
say @a[1,2] # one, two
my $json = ["zero","one", "two","three"];
say $json[1,2] # ["one","two"]

Completely Re-implemented cli with Getopt::Parse (included in lib for now)
"\c[...]" now pads emojis (So) with a space so they display properly
Add new shorthand >info/warn syntax which is short for >info !>warn
Add new is logged-as trait for declaring that a command should be logged with a certain path e.g. constant Cmd $:docker is logged-as("\c[WHALE]")
Update Docker for new "docker community edition" release method

Add JSON setting methods

my $json = {};
$json[0] = "foo";
$json<foo> = "bar"
$json<bar> = { "some" : "object" };

Add JSON.merge and JSON.ACCEPTS

0.0.30

Move return type sigils from back to front of routine declaration: sub ~foo($a) { ... } is now sub foo($a)~.
NOTICE * return type sigil to ^. * has a new meaning.
- ^ represents whatever class I'm in better than *
- * now means return whatever context I'm in

New Feature: Logging, $*log/--log turn on logginng:

Jun 16 01:42:50|ℹ|👻|Updating package list because it doesn't exist at /var/cache/apk/
Jun 16 01:42:50|❔|📦|fetch http://dl-cdn.alpinelinux.org/alpine/v3.5/main/x86_64/APKINDEX.tar.gz
Jun 16 01:42:50|❔|📦|fetch http://dl-cdn.alpinelinux.org/alpine/v3.5/community/x86_64/APKINDEX.tar.gz
Jun 16 01:42:50|❔|📦|v3.5.2-101-g231b864869 [http://dl-cdn.alpinelinux.org/alpine/v3.5/main]

New Feature: q{..}, qq{...} and Q{...} are now "sheardocs", which get rid of leading whitespace up to the first non-whitespace character after the first newline
```
    Q{
      one
      two
      three
    }
```
Is "one\ntwo\nthree\n". This is still a WIP and may change.
New Feature: ssh support through new classes:
- SSHd with methods to start and interact with the sshd command
- SSH-keypair with method to create, delete and interact with SSH-keypairs
- SSH-publickey with methods to inspect a SSH public key
New Feature: start statement prefix, which starts an asynchronous process
```
my $pid = start sleep 5;
say "I don't have to wait for sleep!";
say "It's process is $pid";
```
Still a WIP. Problems .wait'ing on them because the wait shell builtin only waits for direct children. In the above example it works but it won't if the pid comes from a subshell.

New Feature: HTTP.request. Fully featured HTTP user-agent based on curl. Vanilla GET request:

my $resp = HTTP("httpbin.org/bytes/42").request('GET');
ok $resp.is-success, '.is-success';
ok $resp.code == 200, 'code is 200';
is $resp.message, 'OK', '.message is OK';
ok $resp.body.bytes == 42, '.body.bytes is right';
ok $resp.body-size == 42, '.body-size is the same';
is $resp.req-headers.host, 'httpbin.org', '.req-headers.host';
is $resp.http-version, '1.1', '.http-version';

0.0.29

NOTICE: routine return type syntax has changed:
- foo(...-->Type) is not sub foo(...)-->Type
New Feature: Perl 6 style Parameter defaults (!)
- sub foo($foo = "bar", :$bar = "bar") {...}
New Feature: Runtime arguments to eval
- You can now do:
```
my $foo = "bar";
my $shell = eval(:$foo){ my $*foo; say $*foo };
```
And spit will insert the runtime value for $foo into the compiled script

New Feature: start { } blocks which are an interface to & asynchronous lists

It returns a PID (maybe one day a promise)
Used like:

    my $pid = start sleep 1000;
    say "waiting for a while";
    sleep 10;
    if $pid {
      note "it's still running. Killing it";
      .kill;
    }

File.write .move and .chmod return the invocant now.
Add Str.substr which does what you expect
Add Str.random which produces random strings
Add List.pick (same as Perl 6)
Add PID.children and PID.descendants
Add &kill and List[PID].kill
Add &wait and List[PID].wait and PID.wait
New phasers that run after END: FILE-CLEAN and CHECK-CLEAN
Add List[JSON].sort($key) which can sort a list of JSON objects based on the value in a certain key
Add $*socat and add it to spit-helper

0.0.28

Add $*set-delimiter and § quote metachar to refer to it (works in '' and "")
Add Pair type
Add List[Pair] as our de-facto dictionary like object. It has:
- at-key
- set-key
- delete-key
- exists-key
Add <...> and {...} postcircumfixes as shortcuts for at-key/set-key
Add JSON class (WIP)
Add j{...} JSON quoting used like j{ one => 1, two => 2, three => 3}
Add File.sha256
Add $*jq for getting jq (currently pulls a binary from github)
Add Str.substr-re (WIP leading up to ~~ s/foo/bar/g etc)
New Feature: Perl 6 style C-style for loop

# e.g two at a time iteration
my @a = <one two three four>;
loop (my $i = 0; $i < @a; $i += 2) {
    say @a[$i], @a[$i+1];
}

New Feature: Perl 6 Q{...} and ｢...｣ quotes
New Feature: Perl 6 "\x[...]" quotes and \a \b \f \r escape sequences
New Feature: Slurpy positional parameters:

sub foo($a, $b, *@c) {
    say "$a, $b, @c";
}

0.0.27

Add DateTime.Bool (which calls .valid)
Make lt, gt, ge and le work
Add File.ctime to get the last changed time from a file
Add DateTime.epoch-start (1970-01-01T00:00:00.000)
Add resources/tools/spit-helper.sp which builds an image with a few useful default things installed. I hope to use it to deploy scripts.
- Add spit helper build to build the helper
- Add -h and --in-helper to spit compile to run the script in the helper
Add Str.extract which treats the content as a tgz and extracts it
Add Cmd.path to get the path to a command
.call: args syntax works with topic calls
Add $!spit-version to give you the version of spit as a variable

0.0.26

Many bug fixes and new features but not much new documentation.

Add ${ ... } for making a list with command syntax. E.g. my @cmd = ${ printf "foo" }
Add short syntax for declaration a routine body as a command. E.g. Instead of sub foo { ${ printf "foo"} } you can just do sub foo ${printf "foo"}.
Add DateTime and Date (no docs yet)
File.touch returns a Bool
Add File.mtime which returns a DateTime of the mtime
Add $*gcc-make for getting gcc, make and libc development headers
Add File.cleanup which will add the file to the list of temp files to be cleanup up at END
Add -D switch to execute script in an already running docker container
Add GitHubRepo.release-url and .latest-release-url
Add Pkg.ensure-install which installs it only if a version isn't already installed.
The test harness is now written in spit and lives in tools/harness.
Add $*docker-socket to replace Docker.socket.
Add GitHubRepo $*moby-github
Add Docker.start-sleep which keeps a container sleeping so it can be exec'd into.
File.push now returns the pushed item.
Str.write-to now returns what was written
Add Str.append-to which appends to a file and returns what was appended.

0.0.25

Add .grep and .first for List and File
Much more piping between commands instead of command substitution. Now, something like:
```
say <one two three four five>.grep(/e/).elems;
```
compiles into:
```
say "$(list one two three four five|egrep e|elems)";
```
Much much nicer :)
@self is gone
You can now augment parameterized classes. E.g List[Int].sum is implemented like:

augment List[Int] {
    method +sum { $self.${ awk '{ i += $0 } END { printf i }' } }
}
...
say <1 2 3 4>.sum #->10, only works on List[Int].

0.0.24

Added Perl 6 colon method call argument form class.method: args
Added File.archive, which creates a tgz from a directory
Added File.extract which extracts a tgz to a directory and returns it
Added Docker.commit which returns a DockerImg
Added Docker.copy to copy files into a container with docker cp.
Added HTTP.get-file which gets a remote file and saves it to file system.

No docs for the above because it's all WIP

0.0.23

Add Docker, $*docker, $*docker-cli (WIP)
Add -s/--mount-docker-socket switches to mount /var/run/docker.sock if running script inside a container.
Add $*curl
Add File.move-to
POSIX OS has been removed
Linux OS has been added
("foo:$_" if $foo) now reduces down to ${foo:+"foo:$foo"}
$*interactive now defaults to False
- -i cli switch to set $*interactive to $!IN.tty
- -I cli switch to force $*interactive to True

0.0.22

CLI overhauled. See spit --help.
option expression prefix changed from '->' to just ':'. You can now escape it with a : if you want to start with a literal ':'

0.0.21

Add File.mkdir
Add File.cd
Add a :dir option to File.tmp to create a tmp directory.
Add spit-dev command in root of src to be used instead of ./bin/spit for development.
Renamed $$ to $!PID
Renamed File.create to File.touch
Renamed File.child to File.add
Routines that just do concatenation can now be inlined

0.0.20

FD.next-free now uses /proc to figure out what FD is free.
Fixed bug where > type comparisons would fail if both sides were know at compile time.

0.0.19

File.read renamed to File.slurp
Type blessing syantax changed from File{"foo"} to File("foo")
Add GitHubRepo which represents a guthub repo owner/repo-name like GitHubRepo<spitsh/spitsh>

  #or
  env $MY_ENV_VAR = "foo";
```

0.0.18

Regex system redesigned and re-implemented
- regex parsing is now done during the parse phase (no more 2-pass parsing)
- The compiler now has the responsibility of inserting interpolations into the regex pattern that is eventually chosen
Add PID class which is a blessed int representing a process ID
Add $!PID which holds the PID for the main script
Add $$ which gives access to the shell's $$
spit eval now reads from STDIN if it doesn' have an argument

0.0.17

add Str.matches which is like .match but doesn't set @/.
~~ and ACCEPTS have been overhauled. Classes now can have their own .ACCEPTS method which controls what ~~ returns.
SPIT_SETTING_DEV=1 can be set when you are working on core code to recompile the SETTING after you make changes.

0.0.16

Precompilation of CORE setting and core modules. Compilation is much faster now.

0.0.15

new .NAME meta-method which returns the name of a variable $a.NAME -> "a" or "a_1" etc
Better inlining of blocks all around
Reworked FD after investigating how exec(1) actually works:
- .open-w and .open-r been removed. They both did the same thing. They are replaced with .dup which AFAICT is what exec is actually doing when you use it with two file descriptors
- open-file-w/open-file-r has been renamed to open-w and open-r
- open-rw has been added
- writable has been renamed to is-open which is what it actually does.
Added FD.get and FD.getc (which isn't working on Debian/dash yet)

0.0.14

$? variable representing the exit status of the last command executed.

You can now have multiple statements inside (...). E.g.

say ( say 'inside goes first!'; "the will print second");

This is especially useful in conditionals

my $str = '';
my @a =  ^100;
my $i = 0;
$i++ while ($str ~= @a[$i]; $str.chars < 20);
say $str;

.match now retruns a Bool and sets the new @/ variable with the matches.

my $regex = rx‘^(.+)://([^/]+)/?(.*)$’;
if 'https://github.com/spitsh/spitsh'.match($regex) {
    .say for @/;
}

0.0.13

Added inline on blocks

constant $foo = on {
    Debian { 'debian' }
    RHEL   { 'redhat'  }
};

0.0.12

Fixed lots of String escaping bugs
Added rx{...} Perl 6 like regex quote
BusyBox is now its own OS
Add Str.match, which matches against a regex and returns the match and any capture groups. This is very much a WIP, but this at least proves it's possible to return regex capture groups separately without using perl.
add .= operator which works for calling methods and commands like:
- my File $tmp .= tmp;
- my $foo = "foo"; $foo .= ${ sed "s/o/e/" };

0.0.11

for and while loops can be used as values like

my @a = for <one two three> { .uc }
say @a eq <ONE TWO THREE> #-> True

0.0.10

Added experimental .PRIMITIVE which returns the primitive type of the node
Parameterized class comparisons List[File] ~~ List[Str] now give correct answer (True)
if statements are now non-itemizing when used as a value. i.e. ${echo ("foo" if False)} passes 0 arguments to echo
Hugely improved error messages esp for "missing '}'" type syntax errors. They are still a WIP though.

0.0.9

when now works even where $_ hasn't been declared
A lot better inlining of if statements.
You can now assign to control statements without putting them in ()
Made variables in "" a bit smarter. It only uses ${curlies} when it needs to now.

0.0.8

Great itemization refactor
- | slip prefix is no longer a thing
- Instead you have @$foo and @(...) to flatten things
- $@foo and $(...) to itemize things
- This is only relevant to ${...} calls and for loops arguments for now as call arguments are always itemized.
- @self now flattens right. It's still very experimental and is going to change a lot soon. I might make it so it's only available if your class inherits from List.
lists as a single call argument is fixed. foo(<one two three>) used to be three arguments. Now it's one.

0.0.7

Completely changed command syntax again. It's now much more terse. ${yum 'install','-y',$self ::>X} => ${yum install -y $self *>X}
- commas removed
- just > instead of :>
- barewords instead of quoting on anything ~~ /[\w|'-']+/

0.0.6

Added CHANGELOG.md ^_^
self becomes $self and @self (no difference between the two yet)
static methods must be labeled static like static method foo() { ... }
