Function Documentation

◆ ClassifyFileForOpening()

FileOpenKind wxm::ClassifyFileForOpening ( const wxString & file )

Which kind of file this is, judged by its name alone.

A "#uuid" suffix, by which a cell in a worksheet can be addressed, is ignored.

◆ FileLooksBinary()

bool wxm::FileLooksBinary ( const wxString & file )

True if the start of the file looks like binary data rather than text.

Looks at the first few kilobytes: a NUL byte, or the signature of a Windows, Linux or macOS executable, counts as binary. A file that can't be read counts as not binary; opening it will report that properly.

◆ MaximaStringLiteral()

wxString wxm::MaximaStringLiteral ( const wxString & str )

A file name as a Maxima string literal, quotes included.

For building commands like load("file"). A file name on Linux and macOS may contain a double quote, which used to end the string early: importing a CSV file named data.csv"),system("... ran a shell command. A backslash is a Maxima escape character too, so an unescaped Windows path lost all of its backslashes.

◆ WhyFileCannotBeOpened()

wxString wxm::WhyFileCannotBeOpened ( const wxString & file )

Why wxMaxima won't open this file, or an empty string if it will.
