34 * The CSV input module has the following options:
36 * single-column: Specifies the column number which stores the sample data for
37 * single column mode and enables single column mode. Multi
38 * column mode is used if this parameter is omitted.
40 * numchannels: Specifies the number of channels to use. In multi column mode
41 * the number of channels are the number of columns and in single
42 * column mode the number of bits (LSB first) beginning at
45 * delimiter: Specifies the delimiter for columns. Must be at least one
46 * character. Comma is used as default delimiter.
48 * format: Specifies the format of the sample data in single column mode.
49 * Available formats are: 'bin', 'hex' and 'oct'. The binary
50 * format is used by default. This option has no effect in multi
53 * comment: Specifies the prefix character(s) for comments. No prefix
54 * characters are used by default which disables removing of
57 * samplerate: Samplerate which the sample data was captured with. Default
60 * first-channel: Column number of the first channel in multi column mode and
61 * position of the bit for the first channel in single column mode.
64 * header: Determines if the first line should be treated as header
65 * and used for channel names in multi column mode. Empty header
66 * names will be replaced by the channel number. If enabled in
67 * single column mode the first line will be skipped. Usage of
68 * header is disabled by default.
70 * startline: Line number to start processing sample data. Must be greater
71 * than 0. The default line number to start processing is 1.
77 * - Determine how the text line handling can get improved, regarding
78 * all of robustness and flexibility and correctness.
79 * - The current implementation splits on "any run of CR and LF". Which
80 * translates to: Line numbers are wrong in the presence of empty
81 * lines in the input stream. See below for an (expensive) fix.
82 * - Dropping support for CR style end-of-line markers could improve
83 * the situation a lot. Code could search for and split on LF, and
84 * trim optional trailing CR. This would result in proper support
85 * for CRLF (Windows) as well as LF (Unix), and allow for correct
87 * - When support for CR-only line termination cannot get dropped,
88 * then the current implementation is inappropriate. Currently the
89 * input stream is scanned for the first occurance of either of the
90 * supported termination styles (which is good). For the remaining
91 * session a consistent encoding of the text lines is assumed (which
93 * - When line numbers need to be correct and reliable, _and_ the full
94 * set of previously supported line termination sequences are required,
95 * and potentially more are to get added for improved compatibility
96 * with more platforms or generators, then the current approach of
97 * splitting on runs of termination characters needs to get replaced,
98 * by the more expensive approach to scan for and count the initially
99 * determined termination sequence.
101 * - Add support for analog input data? (optional)
102 * - Needs a syntax first for user specs which channels (columns) are
103 * logic and which are analog. May need heuristics(?) to guess from
104 * input data in the absence of user provided specs.
