[Bug]: Auto-completion can not work on newly added files

[zc-yoke]

What happened?

I am using CodeLite (version 18.1.0, Windows 10 64-bit) for C++ development. I noticed that when creating a new project, the automatically generated main.cpp supports code auto-completion. However, when I add existing source files to the project, these newly added files do not have auto-completion available when editing them.

Version

18.1.0

Operating system

Windows 10

Steps to reproduce

Relevant log output

clangd requires files to be in the database, so doing a build might solve the issue.

Please read the Language Server Protocol docs, mainly focus on the clangd section.

I deleted all irrelevant files and folders from the entire workspace and the project, with its complete structure shown as follows. Then, I opened the workspace again using CodeLite, and I found that the code auto-completion feature still couldn't be activated for SimpleClass.cpp and SimpleClass.h. However, files newly created via CodeLite (main.cpp, student.cpp, student.h) could still trigger the code auto-completion functionality.

C:.
│  Documents256.workspace
│ 
│  
└─Documents256
        Documents256.project
        main.cpp
        SimpleClass.cpp
        SimpleClass.h
        student.cpp
        student.h

I guess I'm not far from the truth. Copying text from a webpage into the source file also causes the auto-completion feature to malfunction. My code is shown below. When I delete the Chinese comments, the code completion feature works normally again.

#include "animal.h"
#include <iostream>

Animal::Animal() {
  std::cout << "Animal constructor called" << std::endl;
  std::cout << "Animal constructor" << std::endl;
}
Animal::~Animal() {
  std::cout << "Animal destructor called" << std::endl;
  const std::string name = "lucy";
}
//The following Chinese text was copied from a webpage.
//After you remove the following block comment, you can successfully trigger the code completion feature.
/**
实现了 Animal 类的构造函数和析构函数
构造函数和析构函数中简单打印了一条消息可选,用于验证调用
**/

I am aware that UTF-8 text breaks clangd, but only seen it on Linux. For windows, it is working as it should (at least when I tried non ASCII comments in the code).

[eranif]

Can you try the latest release? 18.2 is available and it contains many fixes, including UTF-8 fixes.

https://downloads.codelite.org/

If it does not work (or breaks something) - you can always revert back to 18.1.0: https://downloads.codelite.org/ReleaseArchive.php

I downloaded version 18.2.0 and conducted tests, and I found that the issue still persists. I performed the tests using even more concise code, as shown below:

#include <iostream>
#include <string>
int main(int argc, char **argv)
{
    const std::string str="hellow world";
    std::cout<<str<<std::endl;
	return 0;
}
//一束花的仪式感，永远不会过时

Windows 10, right?

I will use this as a base code to check if it an issue with CodeLite or clangd

[eranif]

This seems to be working fine here. What is the code page you are using? (you can see it the bottom right in the status bar).

[zc-yoke]

Yes (Windows 10 64-bit), I still used the same computer for the test. Please note that I found there was also a correlation with the position of this comment when I was testing. I conducted the tests with a newly created workspace and a brand-new project.

You can also add a large block of Chinese text to the code comment section for testing to increase the probability of triggering the error. The reason I used only a few Chinese characters above is that I actually obtained them by trimming down from a large block of comments. I was trying to identify the specific character that triggered the error, but the result was not satisfactory.

你也可以将一大段中文添加到代码注释块内进行测试，以增大触发错误的概率。
之所以我上面使用了很少的几个中文字符，其实我也是从一大段注释删减得到，
我是想从中找到具体那个字符触发了错误，但结果不理想。#@!！@#@！#-?。
