prestring 0.3.0

source code generation library (with overuse with-syntax)

this is heavily inspired by srcgen .

(todo: gentle introduction)

features

• generating code with with-syntax

• string injection after writing string

generating code with with-syntax

from prestring.python import PythonModule

m = PythonModule()

with m.class_("Point", metaclass="InterfaceMeta"):
    with m.def_("__init__", "self", "value"):
        m.stmt("self.value = value")

    with m.def_("__str__", "self"):
        m.return_("self.value")

output is.

class Point(object, metaclass=InterfaceMeta)
    def __init__(self, value):
        self.value = value

    def __str__(self):
        return self.value

string injection after writing string

from prestring.python import PythonModule

m = PythonModule()

with m.def_("setup", "config"):
    import_area = m.submodule()
    m.sep()
    for k in ["a", "b", "c", "d", "e"]:
        import_area.stmt("from .plugins import {k}_plugin", k=k)
        m.stmt("config.activate({}_plugin)", k)

print(m)

def setup(config):
    from .plugins import(
        a_plugin,
        b_plugin,
        c_plugin,
        d_plugin,
        e_plugin
    )

    config.activate(a_plugin)
    config.activate(b_plugin)
    config.activate(c_plugin)
    config.activate(d_plugin)
    config.activate(e_plugin)
