Sleep

"Sys.sleep" now becomes

this._sleep

Catch all

app::@error
	Print "Oh no, there's an error!"
	Print it.info

Object to string

Now there are 3 stages:

.toStr
.toIdent
.toDescribe

New magic variables

infinity
+infinity
-infinity
not_a_number

Object compare

Returns: -1 (lesser), 0 (equal), 1 (greater)

123.compare( 321 ).print

Access to Java-Classes

myList = Java_{java.util.ArrayList}
myList.toString.print

New format type: t = Type

format = "|{10t}|"
format.fill( 123 ).print
format.fill( 'x' ).print

Open argument for parser-switch

Normal way:

>setOutputFile( "out.txt" )

Open argument:

>setOutputFile "out.txt"

Deprecated and removed:

#>setOutputFile = "out.txt"

Pipe to shell command

123.´echo´.describe
123.´echo´?.describe
123.´echo´??.describe
123.´("echo")´??.describe
123.pipeToCmd( "echo" ).describe

Fix list and map

Prevent changeing size or the type of an item

list = [ 12, 34, 56 ].fix
map = Map( 'a'-> 12, 'b'-> 34, 'c'-> 56 ).fix

List mathematics

Creating a copy

l = [1,2,3,4]
Print l + 7
Print l - 2
Print l * 3
Print l / 2
Print l ++ [8,9]
Print l -- [1,3]

Modify the list

l = [1,2,3,4]
l += 7
l -= 2
l *= 3
l /= 2
l ++= [8,9]
l --= [1,3]

Open arguments for functions (with some restrictions)

Foo.setTitle "New title"
this.print 123

JayMo 0.16 - 06.12.2020

Magic Variables

Some magic constants become magic variables.

E.g.: _THIS > this

this
it
loop
func
app
jmo
cur
each
nil
true
false

Sleep moved

Old:

_THIS.sleep

New:

Sys.sleep

Bit operations

123.bitAnd
123.bitOr
123.bitXor

Is not Nil

a = "foo"
If( foo.isNotNil )
	Print a

Normalize Dec

Decimal numbers will be normalizend to prevent fractals.

This can be turned off with:

>openDec

Next / Break

Count( 5 )
	If( it == 2 )
		Next
	.else( it == 4 )
		Break
	it.print

Auto-VarLet

"abcdef".amount( :b, 'd' > b ).print
"abcdef".amount( a, 'd' > a ).print

"abcdef".mem(c); c.print
"abcdef".mem(:d); d.print

::test(VarLet e)
	e.get.print

f = 1
°test(f)
g = 2
°test(:g)

Final result

Terminate the application with:

app = 0

Terminate a loop with:

loop = 0

Nil-Use

123.nilUse(11,22).print
nil.nilUse(11,22).print

Type-Use

123.typeUse("Int",1,2).print

New option for "jmo"

Direct execution:

jmo -e "Print 123"

jmo --exec "Print 123"

JayMo 0.15 - 26.10.2020

Tree-Block

tree = >>>>
	body
		font-size: 16px
		margin: 20px
		line-height: 1.5
	b, strong
		font-weight: bold
<<<<

tree.show

Tree

t = Tree
t.add("Foo")
t.add("Bar")
t.show

t.get("Foo").add("Boo")
t.get("Bar").pull("Xar").pull("Tar")
t.show

t["Foo","Too","Zoo"]?
t["Bar","Xar","Tar"] = "War"

Auto-Propertys

For propertys, "Get" can be left out:

::getValueX = "myValue"

_THIS.getValueX.print
_THIS.valueX.print

For "Set" a '=' must be added:

::setValueX(x)
	x.toStr.print

_THIS.setValueX(9)
_THIS.valueX = 9

Cutting Strings

Some methods are changed

s = "abcabc"

s.start(3)

s.end(3)

s.from("c")

s.fromFirst("c")

s.fromLast("c")

s.after("c")

s.afterFirst("c")

s.afterLast("c")

s.before("c")

s.beforeFirst("c")

s.beforeLast("c")

s.to("c")

s.toFirst("c")

s.toLast("c")

s.begin("c")

s.append("c")

Create a temporary VarLet as handle vor VarArgs

Object.handle now creates a temporary VarLet to the current object

h = 8.handle
h.get.print

Shortcuts for _EACH

As shortcut for _EACH you can use € and £

l = [4,9,8,2,7,3,6,5]
l.map( $$++ ).print
l.map( €++ ).print

Overwrite .toStr

::toStr = "My own string!"

°print
_THIS.print

Hot execution

Execute a String at runtime

a = 11

# Runs in container
_JMO.exec("a = 22; a.print")
a.print

# This also
"a = 33; a.print".jmo
a.print

Execution with full access to the environment.

>unsafeHotCode

# With full access to variables
_APP.exec("a = 44; a.print")
a.print

Order of arguments for .set and .put changed!

New order: Object, position1, position2, position3, ...

So its clearer: Put/Set that Object there! And it's possible to use a List (VarLet-Handle) for VarArgs

t = Table(2).add(1,2).add(3,4)
t.set(9, 2, 1)
t.put(8, 1, 3)
t.print

Now "[X, Y] = Object" is the shortcut for: "set(Object, X, Y)"

Curly brackets removed, deep-functions integrated in .get, .put, ...

l = [[[2,3]]]
l[1,1,2].print
l.get(1,1,2).print

Deep-Functionality also for Table

t = Table(2)
t.add([11,12],[13,14]).add([21,22],[23,24])
t.get(2,1,2).print

Same with .get, .pull, .set, .put

Sequence.select

l = Range('a','i').toList.print
l.select( 3,5,1,2,8 ).print
l.selectLazy( 1,3,5,7,11,13 ).print

Same for Table, Map, ...

jmo_ext.jar

New Types for Lib:

Json

...

App-Exit-Hook

app::@exit
  "This is the end".print

Keep App running and wait for a direct call of app.exit

app.keep

Assert-Functions which throws an error at invalid values

num = 123

( num.try.assert( $ < 50 ) ).print
( num.try.assertType( "Str" ) ).print
( num.try.assertIs( 'a' ) ).print

( num.try.assert( $ < 50, "My message" ) ).print
( num.try.assertType( "Str", "My message" ) ).print
( num.try.assertIs( 'a', "My message" ) ).print

Formatting atomic objects

F = "|{5}|{3s}|{3i}|{5^d}|{}|"

5.format(F).print
1.2.format(F).print
'9'.format(F).print
true.format(F).print

For styling numbers:

123.style("????").print
123.style("0000").print
123.style("####").print

New functions for Chars, Char and Str

Chars

'3'.isNumber.print

  counter =++
  ( counter >= 5 )

c.end

# app.keep

d = Date(2001,11,17)
d.getDayOfWeek.print

Multi names for functions

  ("foo "+a).print

this.foo(1)
this.bar(2)
this.bak(3)

Inline loop filter

9.times.breakAt(6,7,9).print

9.times.breakIf( cur > 5 ).print
9.times.breakIfNot( cur < 4 ).print

Rotate a table

t = Table(2)
t.add("abc", 19)
t.add("def", 28)

t.print
t.rotate.print
t.rotate( _LEFT ).print
t.rotate( _RIGHT ).print

Null as alias for Nil

nil.print
null.print

Number with exponent

123.456e3.print
123.456E3.print

123.456e+3.print
123.456E+3.print

123.456e-3.print
123.456E-3.print

Hex/Oct/Bin now results in a number of type "Long"

0xABCD.type.print
0o1234.type.print
0b1010.type.print

Numbers with underlines

123_456_789.print

0xa_b_c_d.print

0o1_2_3_4.print
0o1234_56.print

0b1_0_1_0.print
0b1111_1101.print

Prefix replaces Namespace

>prefix("Foo")

::_Test
  "foo".print

_Test.type.print

Alternate notation for Parser-Switches

>prefix = "Foo"

... is the same as:

>prefix( "Foo" )

New classic types: Print, Echo

Print( 123 )
Print( 'a'++3, "lkj", 234 )

Echo( 123 )
Echo( 'a'++3, "lkj", 234 )

Select / Update

l = [ 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h' ]
l.select(3, 2, 6).print
l.update('X', 3, 2, 6).print
l.print

Lazy version where invalid positions will be filled with 'nil'

l.selectLazy(3, 12, 6).print
l.updateLazy('Y', 3, 12, 6).print

Short versions

l{3,2,6}.print
l{3,2,6} = 'X'
l{3,12,6}?.print
l{3,12,6}? = 'x'

This works also for: Map, Table, Tree
