35 | /* |
36 | * The CSV input module has the following options: | |
37 | * | |
72903e9d GS |
38 | * column_formats: Specifies the data formats and channel counts for the |
39 | * input file's text columns. Accepts a comma separated list of tuples | |
40 | * with: an optional column repeat count ('*' as a wildcard meaning | |
41 | * "all remaining columns", only applicable to the last field), a format | |
42 | * specifying character ('x' hexadecimal, 'o' octal, 'b' binary, 'l' | |
43 | * single-bit logic), and an optional bit count (translating to: logic | |
44 | * channels communicated in that column). This "column_formats" option | |
45 | * is most versatile, other forms of specifying the column layout only | |
46 | * exist for backwards compatibility. | |
4a35548b | 47 | * |
72903e9d GS |
48 | * single_column: Specifies the column number which contains the logic data |
49 | * for single-column mode. All logic data is taken from several bits | |
50 | * which all are kept within that one column. Only exists for backwards | |
51 | * compatibility, see "column_formats" for more flexibility. | |
4a35548b | 52 | * |
72903e9d GS |
53 | * first_column: Specifies the number of the first column with logic data |
54 | * in simple multi-column mode. Only exists for backwards compatibility, | |
55 | * see "column_formats" for more flexibility. | |
4a35548b | 56 | * |
72903e9d GS |
57 | * logic_channels: Specifies the number of logic channels. Is required in |
58 | * simple single-column mode. Is optional in simple multi-column mode | |
59 | * (and defaults to all remaining columns). Only exists for backwards | |
60 | * compatibility, see "column_formats" for more flexibility. | |
4a35548b | 61 | * |
72903e9d GS |
62 | * single_format: Specifies the format of the input text in simple single- |
63 | * column mode. Available formats are: 'bin' (default), 'hex' and 'oct'. | |
64 | * Simple multi-column mode always uses single-bit data per column. | |
65 | * Only exists for backwards compatibility, see "column_formats" for | |
66 | * more flexibility. | |
4a35548b | 67 | * |
72903e9d GS |
68 | * start_line: Specifies at which line to start processing the input file. |
69 | * Allows to skip leading lines which neither are header nor data lines. | |
70 | * By default all of the input file gets processed. | |
4a35548b | 71 | * |
72903e9d GS |
72 | * header: Boolean option, controls whether the first processed line is used |
73 | * to determine channel names. Off by default. Generic channel names are | |
74 | * used in the absence of header line content. | |
4a35548b | 75 | * |
72903e9d GS |
76 | * samplerate: Specifies the samplerate of the input data. Defaults to 0. |
77 | * User specs take precedence over data which optionally gets derived | |
78 | * from input data. | |
4a35548b | 79 | * |
72903e9d GS |
80 | * column_separator: Specifies the sequence which separates the text file |
81 | * columns. Cannot be empty. Defaults to comma. | |
82 | * | |
83 | * comment_leader: Specifies the sequence which starts comments that run | |
84 | * up to the end of the current text line. Can be empty to disable | |
85 | * comment support. Defaults to semicolon. | |
86 | * | |
87 | * Typical examples of using these options: | |
88 | * - ... -I csv:column_formats=*l ... | |
89 | * All columns are single-bit logic data. Identical to the previous | |
90 | * multi-column mode (the default when no options were given at all). | |
91 | * - ... -I csv:column_formats=3-,*l ... | |
92 | * Ignore the first three columns, get single-bit logic data from all | |
93 | * remaining lines (multi-column mode with first-column above 1). | |
94 | * - ... -I csv:column_formats=3-,4l,x8 ... | |
95 | * Ignore the first three columns, get single-bit logic data from the | |
96 | * next four columns, then eight-bit data in hex format from the next | |
97 | * column. More columns may follow in the input text but won't get | |
98 | * processed. (Mix of previous multi-column as well as single-column | |
99 | * modes.) | |
100 | * - ... -I csv:column_formats=4x8,b16,5l ... | |
101 | * Get eight-bit data in hex format from the first four columns, then | |
102 | * sixteen-bit data in binary format, then five times single-bit data. | |
103 | * - ... -I csv:single_column=2:single_format=bin:logic_channels=8 ... | |
104 | * Get eight logic bits in binary format from column 2. (Simple | |
105 | * single-column mode, corresponds to the "-,b8" format.) | |
106 | * - ... -I csv:first_column=6:logic_channels=4 ... | |
107 | * Get four single-bit logic channels from columns 6 to 9 respectively. | |
108 | * (Simple multi-column mode, corresponds to the "5-,4b" format.) | |
109 | * - ... -I csv:start_line=20:header=yes:... | |
110 | * Skip the first 19 text lines. Use line 20 to derive channel names. | |
111 | * Data starts at line 21. | |

115 | * TODO | |
116 | * | |
43bdef26 | 117 | * - Extend support for analog input data? (optional) |
5a971176 GS |
118 | * - Optionally get precision ('digits') from the column's format spec? |
119 | * From the position which is "bit count" for logic channels? | |
43bdef26 GS |
120 | * - Determine why analog samples of 'double' data type get scrambled |
121 | * in sigrok-cli screen output. Is analog.encoding->unitsize not | |
122 | * handled properly? A sigrok-cli or libsigrok (src/output) issue? | |
5a971176 GS |
123 | * - Optionally get sample rate from timestamp column. Just best-effort |
124 | * approach, not necessarily reliable. Users can always specify rates. | |
125 | * - Add a test suite for input modules in general, and CSV in specific? | |
126 | * Becomes more important with the multitude of options and their | |
127 | * interaction. Could cover edge cases (BOM presence, line termination | |
128 | * absence, etc) and auto-stuff as well (channel names, channel counts, | |
129 | * samplerates, etc). | |
