nestPython
"what if python, with braces, one line?"
SETUP
Install nestPython by executing the following:
$ pip install nestpython
After importing;
- In order to transpile a string from nestPython to python, use
nestpython.ncompile(str). - In order to execute a nestPython string, use
nestpython.nexec(str). - To transpile files and directories, use the
nestpython.filesmodule:nestpython.files.ncompile(file)transpiles the specified file to a string.nestpython.files.ncompile_to(file)transpiles the specified file to a new file.nestpython.files.nexec(file)executes the specified file.nestpython.files.build(dir, new_dir)transpiles a directory.- arguments can be provided:
indent_amount=1: determines the indentation increment in the resulting python file.transfer_other_files=True: determines whether non-.npy (or .npx) files should be copied into the build directory.replace_previous=False: determines whether already built files should be replaced.erase_dir:bool=None: determines whether the previously built directory should be completely erased. If not specified, you will be asked to specify in the console.cythonic:bool=None: determines if code should be perceived as nestCython or nestPython.tokenlog=False: determines if tokenization progress should be logged.new_file:str=None: determines where to compile a source file. Reverts to the original filename with a .py(x) extension if unspecified.
Alternatively, importing nestPython files directly after importing nestpython.imports or the entire library into a normal python file works too.
Use .npy for nestPython files, .npx for nestCython files.
FEATURING:
braces
Use {, ; and } instead of indentation - indentation and newline characters in source files will be ignored. e.g.:
n = input('Enter Number: ');
if (n % 2 == 0) {
print('n is even')
} else {
print('n is odd')
}
Use ~{ as a shorthand for while True {.
syntactical changes
Several keywords are altered:
| Python | nestPython | Python | nestPython |
|---|---|---|---|
def |
:= |
del |
~> |
return |
=> |
yield |
:> |
in |
-> |
and |
&& |
not in |
!> |
or |
|| |
is |
=& |
:= |
<- |
is not |
!=& |
case |
? |
lambda |
;= |
; |
,, |
-> |
>: |
// |
~/ |
+= 1 |
++ |
-= 1 |
-- |
{ |
-{ |
} |
}- |
A variable like return will be replaced with return_ on transpilation. using pass is never required, do-nothing braces can be left empty.
One-line functions can still be written with colons: := foo(): => bar, same for if-else and for statements.
Cython keywords are also altered for .npx:
| Cython | nestCython |
|---|---|
cdef |
$= |
cpdef |
~$= |
Strings or ternaries do not have to be one-line; if they are not, you can use \ and # to reserve whitespace as follows:
'string \
continues here'
is equivalent to
'string continues here'
and transpiles to a python string with the newline character ignored. This can be used to explicitly reserve whitespace before the newline character.
Same thing can be done with the # character outside of a string:
a if b #
else c
is equivalent to
a if b else c
The # is ignored by the transpiler.
comments
- For block comments, use
/*,*/. - For line comments, use
//. - Block and line comments will be ignored during transpilation.
- For comments that need to be cpiled into python ones, use
/|,|/.
macros
- Use
# (name of the macro) #!(what it stands for)!#to define a macro. - Macros are only accessible within the nesting they were defined in.
- Use
#~ (name of the macro) ~#to undefine the macro. - Use
#? (name of the macro) ?#to get a boolean representing whether the macro is defined. - Use
$(name of the macro)to use the macro. - Macros that are closer to the nesting called are prioritized.
