A LINE_READER that reads from an open file.
~FILE_LINE_READER()
May or may not close the open file, depending on doOwn in constructor.
FILE_LINE_READER(const wxString &aFileName, unsigned aStartingLineNumber=0, unsigned aMaxLineLength=LINE_READER_LINE_DEFAULT_MAX)
Take aFileName and the size of the desired line buffer and opens the file and assumes the obligation ...
FILE * m_fp
I may own this file, but might not.
char * ReadLine() override
Read a line of text into the buffer and increments the line number counter.
bool m_iOwn
if I own the file, I'll promise to close it, else not.
An abstract class from which implementation specific LINE_READERs may be derived to read single lines...
LINE_READER(unsigned aMaxLineLength=LINE_READER_LINE_DEFAULT_MAX)
Build a line reader and fixes the length of the maximum supported line length to aMaxLineLength.
unsigned m_maxLineLength
maximum allowed capacity using resizing.
unsigned m_length
no. bytes in line before trailing nul.
unsigned m_capacity
no. bytes allocated for line.
void expandCapacity(unsigned aNewsize)
Will expand the capacity of line up to maxLineLength but not greater, so be careful about making assu...
char * m_line
the read line of UTF8 text
wxString m_source
origin of text lines, e.g. filename or "clipboard"
char * Line() const
Return a pointer to the last line that was read in.
Is a LINE_READER that reads from a multiline 8 bit wide std::string.
STRING_LINE_READER(const std::string &aString, const wxString &aSource)
Construct a string line reader.
char * ReadLine() override
Read a line of text into the buffer and increments the line number counter.
void ignore_unused(const T &)
#define THROW_IO_ERROR(msg)
static int vprint(std::string *result, const char *format, va_list ap)
int StrPrintf(std::string *result, const char *format,...)
This is like sprintf() but the output is appended to a std::string instead of to a character array.
wxString SafeReadFile(const wxString &aFilePath, const wxString &aReadType)
Nominally opens a file and reads it into a string.
#define OUTPUTFMTBUFZ
default buffer size for any OUTPUT_FORMATTER
