Variables

Variables are like a pot which you can save data in them.

Look at this example:

$myvar = 'this is data'

println($myvar) # output: this is data

NOTE: always put $ before name of variable everywhere

Declaring variables is so easy, only you have to write $<name_of_variable>.

Also you can set variables without value like this example:

$var1
$var2; $var3 # default value is null

NOTE: variable name should not contains ()+-/*%=}{<>[], chars(literal chars)

Using variables in mem calculation

look at this example:

$name = 'parsa' # set name variable

println('hello ' + $name) # output: hello parsa

$num = 12
println($num * 5) # output: 60

$num2 = 4

println($num * $num2 + 1) # output: 49

copy variables in other variables

look at this example:

$var1 = 'hi'
$var2 = 'bye'

println($var1) # output: hi
println($var2) # output: bye

$var2 = $var1

println($var1) # output: hi
println($var2) # output: hi

$name = 'parsa'
$message = 'hello' + $parsa # you can use all of mem calculation features in here
println($message) # output: hello parsa

NOTE: allowed characters for variable name are A-Za-z(or any alpha-bet characters in other languages), &._ characters.

Put mem value to variable

We can set value of mem to variables with this code:

mem 'something'
$myvar = ^

If you put ^ (mem symbol) as value, memory value will put in the variable.

Also you can use that mem alongside another values.

for example:

mem 'parsa'
$message = 'my name is ' + ^
println($message) # output: my name is parsa

mem 10
println((^ + 5) * 2) # output: 30

free(delete) variables

When you set a variable, that var is in memory. you can delete that var with free command:

$somevar = 'some value'
println($somevar) # output: some value

free('somevar')

println($somevar) # you will get VariableError: undefined variable $somevar (because it was deleted by free command)

Also you can make free more than one variables with free command:

free('var_name')

Checking a variable isset

You can check a variable existens with isset command.

look at this example:

$somevar; $v # set `somevar` and `v` variables

println(isset('somevar')) # True
println(isset('v')) # True
println(isset('not_found')) # False

(The True and False are Python booleans).

how it works?

The isset command gets one or more variable names and if all of that vars exist, it will put True in memory and if all or one/more of them are not exists, it will put False in memory

typeof command

You can get the data type of a variable with typeof function.

look at this example:

$mystr = 'hi'
$myint = 20
$myfloat = 15.32
$mybool = False

typeof($mystr); println(^) # output: <class 'str'>
typeof($myint); println(^) # output: <class 'int'>
typeof($myfloat); println(^) # output: <class 'float'>
typeof($mybool); println(^) # output: <class 'bool'>
# also you can use this syntax and use function directly
println(typeof($myint))

This command puts the typeof variable in mem.

(All of Pashmak datatypes are handled by python and you can use all of python variables features).

python datatype methods

datatype of the Pashmak variables, is handled by python. this means you can use all python methods on them.

for example:

$mystring = '  hello world          '
println($mystring->strip()) # output: `hello world`

NOTE: in python, for calling function or access to property of a object, we use . character, but in Pashmak we use -> symbol(like php)

get() and set() functions

get() function can return value of a variable by name as string.

For example:

$name = 'parsa'

println(get('name'))

output:

parsa

Also set function sets value of a variable by name and value:

$name = 'parsa'
println(get('name'))

set('name', 'pashmak')

println($name)

output:

parsa
pashmak
