I believe that more and more people have realized the hatefulness of the author of notepad++. I used to be a user of notepad++. When I saw that its author, a Taiwanese, blatantly used the software to promote his wrong views, I felt that I should do something.
Notepad++ is just a small software, not complicated, and does not support mac and linux platforms. I use an editor almost every day, so why don't I make one myself? By the way, make a cross-platform version. Since his name is notepad++, then I will call it notepad--, to reduce some erroneous remarks and self-righteousness, referred to as ndd. I believe that there are a lot of domestic counterparts who can make this kind of similar small software. But it happens that big companies look down on them, and small companies have no technology, so let me do it.
notepad++ has simple functions and can only be used on windows. It does not support linux and mac platforms, and based on political reasons, if the author of notepad++ continues to die like this, it will be a matter of time before notepad++ will be removed from the shelves in China. At present, there have been a lot of speeches on the Internet, all of which are against the use of notepad++. But the author of notepad++ is still going his own way. He thinks that no one in mainland China can cure it. Although everyone hates it, there is no similar software that can replace it.
In the process of writing the comparison software ccompare, I found that its core function already has the prototype of a text editor. It only takes a little extra effort to become a simple text editor that can basically replace notepad++.
So just do it. After some research, I found that notepad is actually just an outer package, and inside it is scintilla, the core control of the famous open source editor. Therefore, the level of the author of notepad++ is actually far from reaching the height of his self-righteousness. As long as the domestic 996 environment is liberated and programmers are given better personal time, it is conceivable that a large number of excellent free software will emerge in China.
I believe that at least 10% of programmers in China have the ability to write operating systems, compilers, and editors. But everyone was overwhelmed by 996 and a few taels of silver. Only by freeing programmers and freeing them from low-level manual work can China's basic software see hope.
However, it is basically impossible to replace the notepad++ market in a short time. At present, domestic application software, such as text editors, parsers, and compilers, not to mention operating systems, are almost all controlled by foreign countries. I think as an old programmer, although the technology may have been eliminated by the trend, but in terms of the underlying infrastructure, there is still some waste heat that can be used. It is planned to release and maintain the same kind of software that replaces Notepad++ -- notepad -- on the domestic uos system.
As for whether there is a market, whether it will be successful, and whether it can convert the market effect, then leave it to time.
