Help / Re: Linux C::B Nightly r12639 variable expansion query/help
« Last post by sodev on January 17, 2022, 03:23:20 pm »
It was my setup. To fix it I had to do the following:
    curl -O http://archive.ubuntu.com/ubuntu/pool/universe/w/wxwidgets3.0/libwxgtk3.0-gtk3-dev_3.0.5.1+dfsg-2_amd64.deb
    dpkg -i libwxgtk3.0-gtk3-dev_3.0.5.1+dfsg-2_amd64.deb

This is not the way how to install packages from repositories, you better add the required repositories to your configuration and download the package through apt. Manually installing like this is asking for trouble.

Plugins development / Re: Code completion using LSP and clangd
« Last post by ollydbg on January 17, 2022, 02:56:17 pm »
I see there are many pch files in the folder such as:

C:\Users\[myusername]\AppData\Local\Temp\preamble-c7460b.pch

I think those files is created by clangd, and are there any way to automatically delete them when exit C::B?

EDIT:

clangd writes too much disk : CPP-19402

This discussion looks like the pch can keep in "memory". :)

Here is the patch to fix this pch file issue:

I see some error message comes from this function call, but I'm not sure why, this happens when I'm editing source file in the C::B editor.

Code
int ProcessLanguageClient::ReadLSPinputLength()
// ----------------------------------------------------------------------------
{
    // this function is driven by readJson() via the thread in transport::loop()
    // and the incoming data is locked.
    // thread was started in constructor and called from readJason() after locking the buffer

    // "Content-Length: <digits>\r\n\r\n"

    if (Has_LSPServerProcess() and m_std_LSP_IncomingStr.length())
    {
        // search for LSP header
        size_t hdrPosn = m_std_LSP_IncomingStr.find("Content-Length: ");
        if (hdrPosn == std::string::npos)
            return wxNOT_FOUND;
        else //have incoming text
        {
            if (hdrPosn != 0)   // verify LSP header is at beginning of buffer
            {
                // Error: header is not at beginning of buffer. Try to fix it.
                // usually caused by clangd invalid utf8 sequence
                wxString msg(wxString::Format("ERROR:%s(): buffLength (%d): Position of content header %d.\n",
                             __FUNCTION__, int(m_std_LSP_IncomingStr.length()), int(hdrPosn)) );
                msg += "Buffer contents written to client log.";
                #if defined(cb_DEBUG)
                    wxSafeShowMessage("Input Buffer error",msg);
                #endif
                msg += "LSP_IncomingStrBuf:\n" + m_std_LSP_IncomingStr + "\n";
                writeClientLog(msg);
                // adjust the data buf to get clangd header at buff beginning
                m_std_LSP_IncomingStr = m_std_LSP_IncomingStr.substr(hdrPosn);
            }

I just enabled the log file, and see the log message(in C:\Users\[myusername]\AppData\Local\Temp\CBclangd_client-1332.log

And the content of the log file are:

Code
19:45:09.758 ERROR:ReadLSPinputLength(): buffLength (549): Position of content header 112.

Development / Re: event sequence question?
« Last post by AndrewCot on January 17, 2022, 10:32:01 am »
I was looking at the header guard and the other plugins by same author last night and they were not included because they can cause bad side affects if not used/configured correctly. As such these are probably not the best to use as a template.

Headerguard info:    URL info: https://wiki.codeblocks.org/index.php/Header_Guard_plugin    Problem:  The Header Guard plugin is included in Code::Blocks' source code (src/plugins/headerguard/), however, it is not built by default to prevent unexpected behavior.
It would probably be better to do one f the following:1) Create the cbplugin via the project file and leave it up toe the dev to manually install it2) Create the plugin in the devel directory but mod the profess so it does not copy the files to the output directory so it does not get released, but can be used when running he C::B as a debugee.3) Do both options 1 and 2
I am inclined to think option 3 would benefit the developers the most.

I read somewhere that this plugin should be treated like the headerguard, i.e. a core plugin not added to the main project. I think this is the better solution, this way you can install it if needed but it will never go in the nightly/release.

You know better the build system than me. The only constraint is the plugin should not be in the nightly/release, because plugins activate automatically and this would waste time without any benefit for users.

displayevents is in plugins (so not in contrib) which is ok, but I think it better acts as the other plugins then, meaning it does not have its own cbp files, but integrates directly in the CodeBlocks_wx<...>.cbp

What do you think ?

Long time ago, the plugin zip file is only created by the update script. (method A)

Several years ago, some developers are adding the zip command to the cbp files, so once the project is built, the zip file get created. (Method B)

I prefer Method B.   :)

Because for a plugin developer, it should prepare the dll and the zip file for its own plugin.

Nightly builds / Re: The 31 December 2021 build (12618) is out.
« Last post by ollydbg on January 16, 2022, 02:05:40 pm »
Hi, cyuyan.

I think only the official C::B release files were hosted in Fosshub.
While the nightly builds files were only hosted in Sourceforge.

I looked at the tuna's issues, and there is no way to automatically rsync with the SourceForge files.

So, the only way currently is to manually download the nightly builds files and upload to other sites.  :(
