CSV Parser

C library for parsing CSV files

This library is a copy of http://sourceforge.net/projects/cccsvparser/ I've uploaded it here in order to continue development as the original appears to be inactive.

Setup

Current setup assumes you are in a python 3.6+ environment.

$ make -C src all
$ python3 -m setup.py build_ext --inplace --include-dirs=src/
$ python setup.py develop
$ python -c "import csvparser_cffi; print(csvparser_cffi.__file__)"

Example usage:

#include <stdio.h>

#include "csvparser.h"

int main() {
    int i =  0;
    //                                   file, delimiter, first_line_is_header?
    CsvParser *csvparser = CsvParser_new("Book1.csv", ",", 1);
    CsvRow *header;
    CsvRow *row;

    header = CsvParser_getHeader(csvparser);
    if (header == NULL) {
        printf("%s\n", CsvParser_getErrorMessage(csvparser));
        return 1;
    }
    char **headerFields = CsvParser_getFields(header);
    for (i = 0 ; i < CsvParser_getNumFields(header) ; i++) {
        printf("TITLE: %s\n", headerFields[i]);
    }
    // CsvParser_destroy_row(header); -> causes error in current version
    while ((row = CsvParser_getRow(csvparser)) ) {
        printf("NEW LINE:\n");
        char **rowFields = CsvParser_getFields(row);
        for (i = 0 ; i < CsvParser_getNumFields(row) ; i++) {
            printf("FIELD: %s\n", rowFields[i]);
        }
        CsvParser_destroy_row(row);
    }
    CsvParser_destroy(csvparser);
    return 0;
}
