FindFile()

template<class Container >

std::string EA::FileUtils::FindFile ( const std::string &  fileName, const Container &  folders, bool  cwd = false  )

static

Search for the given file inside the given folders.

This method searches for a file inside a list of folders. The file name is concatenated to each folder and the existence is then checked, so #fileName can also be a relative path. If #cwd is set to true then the file will be searched also relatively to the current working directory. If #fileName is an absolute path then #folders and #cwd will be ignored. The return value is the full path of the file, or an empty string if the file has not been found.

Parameters

fileName	The name of the file (possibly an absolute or relative path).
folders	The list of folders where the file will be searched.
cwd	If true, the file will be searched also in the current working directory.

Returns

a string with the full path to the found file; an empty string if the file is not found.

GetCWD()

std::string EA::FileUtils::GetCWD ( )

static

Get the current working directory.

Returns

A string containing the name of the current working directory.

Glob()

template<template< class, class > class Container>

Container< std::string, std::allocator< std::string > > EA::FileUtils::Glob ( const std::string &  pattern )

static

Find all files matching a pattern.

This function returns all the file names matching the input pattern. The return value is by default a std::vector<std::string>. If another type of container for the return strings is desired then it can be specified in the function call. For example:

auto filesVect = FileUtils::Glob(pattern); // Returns a std::vector<std::string> auto filesList = FileUtils::Glob<std::list>(pattern); // Returns a std::list<std::string>

Parameters

pattern

The glob expression to be matched.

Returns

All the file names matching the given pattern.
