03/10/2019 – updated to v. 1.5 (menubar)
04/10/2019 – updated to v. 1.5 (highlight code)
What is this?
This is a little project to show some tkinter features, but it can be also used to make something interesting. You can create different txt files from the app, edit the text, change their names, delete them, having the different files in a list on the right of the app and you can also convert them into an html page with all the text in the different files or a html page with the text of a single page. It accept plain text to wich you can add some symbols at the beginning of a line to make some sort of markup or use html tags directly. I am actually using it and I will add new features (like committing the files to a github repository as you save the files) in the future.
Version 1.4c2
In version 1.42c3-user-edition added the ctrl+p to save the html page of a single txt file
Download it in the githun repository.
Final version post
Organize a complex ebook in simple txt files, add html tags and images with special characters, from simple txt files. This is the aim of this app. Another aim is to get better at knowing tkinter’s widgets and how to start making a GUI, from skratch. This is PyEbooksMaker or Python Ebooks Maker.
In the last days we have seen how to make a sort of ebook maker, to organize our work with a simple app and then create an html file with all the work that could easily become an true ebook. There is an update to the final version with many new features, like you can see in the the following paragraph.
New features
I added some new features to the app:
- rename files (with the button or pressing F2)
- delete files
- chance to insert
- H2 tag with *
- H3 tag with ^
- images with # tag
So, now, it is almost a complete app, even if it is very rough and need to be refined.
This is the code, until now,:

Updates
1.42c3-user-edition
In version 1.42c3-user-edition added the ctrl+p to save the html page of a single txt file.
Update 1.4c2
Save single page
Now you can save a single page (save page button). This page will be rendered in html and saved by itself into the text directory. I am using this in case I want to render a single page to use without the whole ebook in a site or in any different ‘places’. There are some future features that I could implement and that I use to automatically add this pages into a site of github.io.
Future: Commit to github
This is related to what I wrote in the previous paragraph. If you want to use it for you, you must change the address of the repository, of course. You need to adapt the code to your needs. I will try to make it usable by others, but for now you can ignore it (the buttons are commented).
Images
Now you can use the # symbol to add Internet addresses of images and not only names of files stored into the img folder.
Update 1.3
22.09.16
- creates folders text and img if not present
- new symbol => for red color
- ctrl + b shows the Ebook
Control if text and img folder are present, if not it creates them (in the if __name__ == “__main__ …”)
if "text" in os.listdir():
print("text folder exists")
else:
os.mkdir("text")
print("text folder created")
if "img" in os.listdir():
print("img folder exists")
else:
os.mkdir("img")
print("text folder created")
Added a new symbol “=>” that gives a red color to the text that follows it.
The code is in the method save_ebook
elif line[0] == "=" and line[1]== ">":
line = line.replace("=>", "")
html += f"<span style='color:red'>{line}</span>"
I added the instruction on the left
self.lab_help = tk.Label(self.frame2, text="Symbols:\n-------\n* = <h2>\n^ = <h3>\n# = <img...\n=> = red", bg="coral")
Now with ctrl + b you can create the ebook without using the button on the left.
This line of code does the job in the last line of the __init__ method of the class Ebook
self.root.bind("<Control-b>", lambda x: self.save_ebook())
Update 1.2
22.09.2019 – Added the wrap = tk.Word to the arguments of
self.text = tk.Text(self.root, wrap=tk.WORD)
to make the words to to the next line without splitting them in a weird way.
Update 1.5
I added a menubar, instead of the buttons on the left side of the window.
self.menubar = tk.Menu(self.root)
self.menubar.add_command(label="[ + ]", command = lambda: self.new_window(Win1))
self.menubar.add_command(label="[ Delete ]", command= lambda: self.delete_file())
self.menubar.add_command(label="[ Rename ]", command= lambda: self.new_window(Rename))
self.menubar.add_command(label="[ Page ]", command = self.save_page)
self.menubar.add_command(label="[ Ebook ]", command = self.save_ebook)
self.menubar.add_command(label="[ SAVE ]", command = self.save)
self.menubar.add_command(label="[ Help ]", command= lambda: self.new_window(Help))
self.root.config(menu=self.menubar)
This is how the window looks now (prettier and with more space for the text and list of files).

Update 1.6 – highlight code
I added a way to highlight the code (for Python) when you write the code like this
>>> print(“Hello”)
def highlight(self, code):
"pass a string and it will be highlighted"
# keywords to be colored in orange
kw = kwlist
for k in kw:
k = k + " "
code = code.replace(k, "<b style='color:orange'>" + k + "</b>")
code = code.replace("\n","<br>")
#print(code)
# The 'indentation'
code = code.replace("\t", " ")
# functions to be clored in blue
_def= re.findall("\w+\(", code)
for w in _def:
code = code.replace(w, "<b style='color:blue'>" + w[:-1] + "</b>(")
return code
In the html_converter I added this line (we need to import re and kwlist from keyword):
import re from keyword import kwlist
if line[0] == ">":
line = self.highlight(line) + "<br>"
html += line
