Commands: shell - Shell mode. After this a series of word pairs should occur. The first is the environment var to set and the second is the key to set it from. Use like: eval `apt-config shell QMode apt::QMode` ##################################################################### */ /*}}}*/ // Include Files /*{{{*/ #include<config.h> #include <apt-pkg/cmndline.h> #include <apt-pkg/error.h> #include <apt-pkg/init.h> #include <apt-pkg/strutl.h> #include <apt-pkg/configuration.h> #include <apt-pkg/aptconfiguration.h> #include <apt-pkg/pkgsystem.h> #include <iostream> #include <string> #include <vector> #include <map> #include <string.h> #include <apt-private/private-cmndline.h> #include <apt-private/private-main.h> #include <apti18n.h> /*}}}*/ using namespace std; // DoShell - Handle the shell command /*{{{*/ // --------------------------------------------------------------------- /* */ static bool DoShell(CommandLine &CmdL) { for (const char **I = CmdL.FileList + 1; *I != 0; I += 2) { if (I[1] == 0 || strlen(I[1]) == 0) return _error->Error(_("Arguments not in pairs")); string key = I[1]; if (key.end()[-1] == '/') // old directory format key.append("d"); if (_config->ExistsAny(key.c_str())) cout << *I << "='" << SubstVar(_config->FindAny(key.c_str()),"'","'\\''") << '\'' << endl; } return true; } /*}}}*/ // DoDump - Dump the configuration space /*{{{*/ // --------------------------------------------------------------------- /* */ static bool DoDump(CommandLine &CmdL) { bool const empty = _config->FindB("APT::Config::Dump::EmptyValue", true); std::string const format = _config->Find("APT::Config::Dump::Format", "%f \"%v\";\n"); if (CmdL.FileSize() == 1) _config->Dump(cout, NULL, format.c_str(), empty); else for (const char **I = CmdL.FileList + 1; *I != 0; ++I) _config->Dump(cout, *I, format.c_str(), empty); return true; } /*}}}*/ static bool ShowHelp(CommandLine &) /*{{{*/ { std::cout << _("Usage: apt-config [options] command\n" "\n" "apt-config is an interface to the configuration settings used by\n" "all APT tools, mainly intended for debugging and shell scripting.\n"); return true; } /*}}}*/ static std::vector<aptDispatchWithHelp> GetCommands() /*{{{*/ { return { {"shell", &DoShell, _("get configuration values via shell evaluation")}, {"dump", &DoDump, _("show the active configuration setting")}, {nullptr, nullptr, nullptr} }; } /*}}}*/ int main(int argc,const char *argv[]) /*{{{*/ { // Parse the command line and initialize the package library CommandLine CmdL; auto const Cmds = ParseCommandLine(CmdL, APT_CMD::APT_CONFIG, &_config, &_system, argc, argv, &ShowHelp, &GetCommands); std::vector<std::string> const langs = APT::Configuration::getLanguages(true); _config->Clear("Acquire::Languages"); for (std::vector<std::string>::const_iterator l = langs.begin(); l != langs.end(); ++l) _config->Set("Acquire::Languages::", *l); std::vector<std::string> const archs = APT::Configuration::getArchitectures(); _config->Clear("APT::Architectures"); for (std::vector<std::string>::const_iterator a = archs.begin(); a != archs.end(); ++a) _config->Set("APT::Architectures::", *a); string const conf = "APT::Compressor::"; std::map<std::string,std::string> CompressorNames; for (auto && key : _config->FindVector("APT::Compressor", "", true)) { auto const comp = conf + key + "::Name"; CompressorNames.emplace(_config->Find(comp, key), key); } std::vector<APT::Configuration::Compressor> const compressors = APT::Configuration::getCompressors(); _config->Clear("APT::Compressor"); for (std::vector<APT::Configuration::Compressor>::const_iterator c = compressors.begin(); c != compressors.end(); ++c) { auto const n = CompressorNames.find(c->Name); string comp = conf + (n == CompressorNames.end() ? c->Name : n->second) + "::"; _config->Set(comp + "Name", c->Name); _config->Set(comp + "Extension", c->Extension); _config->Set(comp + "Binary", c->Binary); _config->Set(std::string(comp + "Cost").c_str(), c->Cost); for (std::vector<std::string>::const_iterator a = c->CompressArgs.begin(); a != c->CompressArgs.end(); ++a) _config->Set(comp + "CompressArg::", *a); for (std::vector<std::string>::const_iterator a = c->UncompressArgs.begin(); a != c->UncompressArgs.end(); ++a) _config->Set(comp + "UncompressArg::", *a); } std::vector<std::string> const profiles = APT::Configuration::getBuildProfiles(); _config->Clear("APT::Build-Profiles"); for (std::vector<std::string>::const_iterator p = profiles.begin(); p != profiles.end(); ++p) _config->Set("APT::Build-Profiles::", *p); return DispatchCommandLine(CmdL, Cmds); } /*}}}*/
