A simple python script to write .desktop files.

desktopwriter.py

app_name = input("Application Name: ")
comment = input("Tooltip: ")
generic_name = input("Generic Name: ")
exec_name = input("Path to exec: ")
icon = input("Path to icon: ")
app_type = "Application"
categories = []

more_categories = True
while(more_categories):
    more_categories_input = input("Add more categories? y/n")
    if(more_categories_input != "y"):
        more_categories = False
    new_category = input("Category: ")
    categories.append(new_category + ";")

print(app_name, comment, generic_name, exec_name, icon, app_type, categories)

file_name = app_name + ".desktop"
with open(file_name, "w") as file:
    file.write("[Desktop Entry]\n")
    file.write("Name=" + app_name + "\n")
    file.write("Comment=" + comment + "\n")
    file.write("GenericName=" + generic_name + "\n")
    file.write("Exec=" + exec_name + "\n")
    file.write("Icon=" + icon + "\n")
    file.write("Type=" + app_type + "\n")
    file.write("Categories=")
    file.writelines(categories)

#TODO: add more parts of the .desktop spec
