Member Function Documentation

absolutePath()

string system::absolutePath ( const std::string &  path, const std::string &  cwd = getCwd()  )

static

absolutePath returns the absolute path of relative path w.r.t. given cwd

Parameters

path	relative path
cwd	if empty, the current working dir is used

Returns

absolute path

buildCmdLine()

string system::buildCmdLine ( int  argc, const char *const *  argv  )

static

buildCmdLine little helper to reconstruct cmd line string from main(...) args

Parameters

argc
argv

Returns

properly build string from argc and argv

exec()

string system::exec ( const std::string &  cmd )

static

execute given cmd and return stdout (stderr is suppressed)

Parameters

cmd	the command to execute

Returns

stdout of cmd

getCwd()

string system::getCwd ( )

static

getCwd determines current working directory (cwd)

Returns

properly constructed std::string containing cwd

isDeadLink()

bool ant::std_ext::system::isDeadLink ( const std::string &  filename )

static

Check if filename is a dead symlink.

Parameters

filename

Returns

isInteractive()

bool system::isInteractive ( )

static

Check if running an interactive shell / if a TTY is attached to stdin.

Returns

lsFiles()

list< string > system::lsFiles ( const std::string &  folder = ".", const std::string &  extension = "", bool  ignoreDotDirs = false, bool  doNotPrependFolder = false  )

static

list files in a directory

Parameters

folder	Path to directory to list
extension	File extension to look for. all files if empty.

Returns

a list of all filenames with path prepended

path_exists()

bool ant::std_ext::system::path_exists ( const std::string &  path )

static

Check if a path/file exists. For symlinks: only check the link itself, independent from destination.

Parameters

path

Returns

testopen() [1/2]

bool ant::std_ext::system::testopen ( const std::string &  filename, std::string &  errmsg  )

static

testopen a given file

Parameters

filename	to open as test
errmsg	non-empty if unsuccessful open
