66.6.1 EOL Conversion

nil

Automatically detect the end-of-line type (LF, CRLF, or CR). Also generate subsidiary coding systems named name-unix, name-dos, and name-mac, that are identical to this coding system but have an EOL-TYPE value of lf, crlf, and cr, respectively.

lf

The end of a line is marked externally using ASCII LF. Since this is also the way that SXEmacs represents an end-of-line internally, specifying this option results in no end-of-line conversion. This is the standard format for Unix text files.

crlf

The end of a line is marked externally using ASCII CRLF. This is the standard format for MS-DOS text files.

cr

The end of a line is marked externally using ASCII CR. This is the standard format for Macintosh text files.

t

Automatically detect the end-of-line type but do not generate subsidiary coding systems. (This value is converted to nil when stored internally, and coding-system-property will return nil.)
