◆ check_newline()

int check_newline ( const String & s )

Checks if there is exactly one newline character at the end of the string.

Parameters

s	The String to check.

Returns: Error code (0=ok, 1=empty, 2=missing, 3=extra newline

◆ cleanup_output_file()

void cleanup_output_file	(	ofstream &	,
		const String &
	)

Closes the file.

If it is empty, the file is deleted.

Parameters

file	File pointer

Author: Oliver Lemke

Exceptions

ios_base::failure Could for example mean that the directory is read only.

◆ expand_path()

String expand_path ( const String & path )

Expands the ~ to home directory location in given path.

Parameters

[in] path String with path

Returns: Expanded path.

◆ file_exists()

bool file_exists ( const String & filename )

Checks if the given file exists.

Parameters

filename File to check.

Returns: Error code (true = file exists, false = file doesn't exist)

◆ filename_ascii()

void filename_ascii	(	String &	filename,
		const String &	varname
	)

Gives the default file name for the ASCII formats.

The default name is only used if the file name is empty.

Parameters

filename	Output: file name
varname	variable name

◆ find_file()

bool find_file	(	String &	filename,
		const char *	extension
	)

Find the given file.

If it doesn't exist in the current directory, also search the include path.

Parameters

filename	File to check.
extension	Extension tried to be appended to the filename.

Returns: Error code (true = file found, false = file not found)

◆ open_input_file()

void open_input_file	(	ifstream &	file,
		const String &	name
	)

Open a file for reading.

If the file cannot be opened, the exception IOError is thrown.

Parameters

file	File pointer
name	Name of the file to open

If the file cannot be opened, the exception IOError is thrown.

Parameters

file	File pointer
name	Name of the file to open
