Code Completion with One Key Press
oBFusCATed:
I doubt, the only thing you can do is start debugging the CC plugin.
You can probably try the CC based on clang mentioned by yvesdm3000.

This is because the setting here will be shared by all kinds of code completion plugins, I mean we have a lot of cc plugins, such as the build in cc, the clang cc, the python cc.

Hi, I think it can be adjusted, but I don't know how to do that, in the source code:
--- Code: ---void CodeCompletion::DoCodeComplete(int caretPos, cbEditor* ed, std::vector<CCToken>& tokens, bool preprocessorOnly)
--- End code ---
There are some snippet:
--- Code: ---if (colour_set)
{
wxString lastSearch = m_NativeParser.LastAIGlobalSearch().Lower();
int iidx = ilist->GetImageCount();
FileType fTp = FileTypeOf(ed->GetShortName());
bool isC = (fTp == ftHeader || fTp == ftSource|| fTp == ftTemplateSource);
// theme keywords
HighlightLanguage lang = ed->GetLanguage();
if (lang == HL_NONE)
lang = colour_set->GetLanguageForFilename(ed->GetFilename());
wxString strLang = colour_set->GetLanguageName(lang);
// if its sourcecode/header file and a known fileformat, show the corresponding icon
if (isC && strLang == wxT("C/C++"))
stc->RegisterImage(iidx, wxBitmap(cpp_keyword_xpm));
else if (isC && strLang == wxT("D"))
stc->RegisterImage(iidx, wxBitmap(d_keyword_xpm));
else
stc->RegisterImage(iidx, wxBitmap(unknown_keyword_xpm));
// the first two keyword sets are the primary and secondary keywords (for most lexers at least)
// but this is now configurable in global settings
for (int i = 0; i <= wxSCI_KEYWORDSET_MAX; ++i)
{
if (!m_LexerKeywordsToInclude[i])
continue;
wxString keywords = colour_set->GetKeywords(lang, i);
wxStringTokenizer tkz(keywords, wxT(" \t\r\n"), wxTOKEN_STRTOK);
while (tkz.HasMoreTokens())
{
wxString kw = tkz.GetNextToken();
if ( kw.Lower().StartsWith(lastSearch)
&& uniqueStrings.find(kw) == uniqueStrings.end() )
{
tokens.push_back(CCToken(wxNOT_FOUND, kw, iidx));
}
}
}
}
--- End code ---
You see, all the keywords were added directly to the "tokens", but I think they don't have much precedence, as I can see the cunstructor of CCToken.
--- Code: --- /** Structure representing a generic token, passed between CC plugins and CCManager. */
struct CCToken
{
/** @brief Convenience constructor.
*
* Represents a generic token, passed between CC plugins and CCManager.
*
* @param _id Internal identifier for a CC plugin to reference the token in its data structure.
* @param dispNm The string CCManager will use to display this token.
* @param categ The category corresponding to the index of the registered image (during autocomplete).
* Negative values are reserved for CCManager.
*/
CCToken(int _id, const wxString& dispNm, int categ = -1) :
id(_id), category(categ), weight(5), displayName(dispNm), name(dispNm) {}
/** @brief Construct a fully specified CCToken.
*
* Represents a generic token, passed between CC plugins and CCManager.
*
* @param _id Internal identifier for a CC plugin to reference the token in its data structure.
* @param dispNm The verbose string CCManager will use to display this token.
* @param nm Minimal name of the token that CCManager may choose to display in restricted circumstances.
* @param _weight Lower numbers are placed earlier in listing, 5 is default; try to keep 0-10.
* @param categ The category corresponding to the index of the registered image (during autocomplete).
* Negative values are reserved for CCManager.
*/
CCToken(int _id, const wxString& dispNm, const wxString& nm, int _weight, int categ = -1) :
id(_id), category(categ), weight(_weight), displayName(dispNm), name(nm) {}
int id; //!< CCManager will pass this back unmodified. Use it as an internal identifier for the token.
int category; //!< The category corresponding to the index of the registered image (during autocomplete).
int weight; //!< Lower numbers are placed earlier in listing, 5 is default; try to keep 0-10.
wxString displayName; //!< Verbose string representing the token.
wxString name; //!< Minimal name of the token that CCManager may choose to display in restricted circumstances.
};
--- End code ---
So, we have to adjust the "weight" parameter. We need an algorithm to dynamically adjust the "weight" for each added keywords. ;)

How do you use Clang Code Completion? I've never used any extra Code::Blocks plugins before.

It's a bit simpler than that, it's a CodeBlocks setting that will instruct when the CC plugin will be called for code-completion.
It might be better if this setting would be language-specific, but it's not very important or high priority item...

AlterEgo:
Would someone explain to me how to set up Code::Blocks to use Clang Code Completion or link me to a good tutorial that explains how to do so please?
