Writing contents of bpy.data.texts to folder with bpy.ops.text.save I am reading my scripts from a folder with:
import bpy
import pathlib
for file in pathlib.Path(&quot;C:\\awesome\\scripts\\folder&quot;).iterdir():
    bpy.ops.text.open(filepath = str(file))

Now i can use the scripts in blender itself and may change some stuff here and there. To save a script as a user i can use Alt + S. For scripting this procedure, blender shows a tooltip with bpy.ops.text.save() but i don't know how to define which text i want to save. I guess it will be something like:
import bpy
for text in bpy.data.texts:
    bpy.data.texts.active = text
    bpy.ops.text.save()

But bpy.data.texts.active is actually not available.
TL;DR: Where to define the active text?

You can find current active text object in screen.areas of text editor
area = next(area for area in context.screen.areas if area.type == 'TEXT_EDITOR')
text_obj = area.spaces.active.text

Assume that you know your text-block name, then assign that text type to active text:
area.spaces.active.text = bpy.data.texts['Text.001']

This will change the current active text object.
