Pyeet! Yeet All the Python!

Pyeet is a general-purpose language to embed asynchronous Python in ALL your files.

Pyeet takes the source from FILE and compiles it to a Python module, then runs it.

Source content...                       ...compiled into Python
------------------                      -----------------------
{~# Welcome to Pyeet! #~}               # Welcome to Pyeet!
😊                                      print('😊')
                                        print()
{~~
text = "Hello, World!"                  text = "Hello, World!"
~~}
{~= text =~}                            print(text)
                                        print()
{~~
for x in [99, 98, 97]:                  for x in [99, 98, 97]:
    print(f"{x} bottles of beer…")          print(f"{x} bottles of beer…")

from datetime import datetime           from datetime import datetime
now = datetime.now()                    now = datetime.now()
~~}
The time is {~= now() =~}               print('The time is ', now(), sep='')

Installation

Installation with pip:

$ pip install pyeet

Usage

usage: python -m pyeet [-h] [--dump] FILE

positional arguments:
  FILE        Source file with Pyeet tags

optional arguments:
  -h, --help  show this help message and exit
  --dump      Dump generated python module

Examples

Insert the current date and time into PostScript

PostScript sadly doesn't have any function that can get the current time. We can fix that!

In the repo there is a tests folder that contains the following file:

current_date_and_time_in_postscript.ps

%!PS
% 595 842 scale
/Times-Roman findfont
20 scalefont
setfont
newpath
70 750 moveto
{~~
from datetime import datetime
~~}
/({~= datetime.now() =~}) show

We can use pyeet and gs (ghostscript) to render our source with the current time:

$ python -m pyeet tests/current_date_and_time_in_postscript.ps \
  | gs -sDEVICE=png16m -sOutputFile=tests/current_date_and_time_in_postscript.png -

The result:

If you're curious, you can dump the compiled Python source using the --dump argument:

$ python -m pyeet --dump tests/current_date_and_time_in_postscript.ps

print('%!PS')
print('% 595 842 scale')
print('/Times-Roman findfont')
print('20 scalefont')
print('setfont')
print('newpath')
print('70 750 moveto')

from datetime import datetime

print('/(', datetime.now(), ') show', sep='')
