33 | /* |
34 | * The CSV input module has the following options: | |
35 | * | |
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. | |
39 | * | |
ba7dd8bb UH |
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 | |
4a35548b | 42 | * column mode the number of bits (LSB first) beginning at |
ba7dd8bb | 43 | * 'first-channel'. |
4a35548b MS |
44 | * |
45 | * delimiter: Specifies the delimiter for columns. Must be at least one | |
46 | * character. Comma is used as default delimiter. | |
47 | * | |
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 | |
51 | * column mode. | |
52 | * | |
53 | * comment: Specifies the prefix character(s) for comments. No prefix | |
54 | * characters are used by default which disables removing of | |
55 | * comments. | |
56 | * | |
57 | * samplerate: Samplerate which the sample data was captured with. Default | |
58 | * value is 0. | |
59 | * | |
ba7dd8bb UH |
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. | |
4a35548b MS |
62 | * Default value is 0. |
63 | * | |
64 | * header: Determines if the first line should be treated as header | |
ba7dd8bb UH |
65 | * and used for channel names in multi column mode. Empty header |
66 | * names will be replaced by the channel number. If enabled in | |
4a35548b MS |
67 | * single column mode the first line will be skipped. Usage of |
68 | * header is disabled by default. | |
69 | * | |
70 | * startline: Line number to start processing sample data. Must be greater | |
71 | * than 0. The default line number to start processing is 1. | |

75 | * TODO | |
76 | * | |
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 | |
de788af4 | 81 | * lines in the input stream. See below for an (expensive) fix. |
ccff468b GS |
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 | |
86 | * line number counts. | |
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 | |
de788af4 | 92 | * is acceptable). |
ccff468b GS |
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. | |
100 | * | |
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. | |
