tsv_utils.common

Utility functions used by tsv-utils programs.

A few of the utilities that may be of more general interest:

• tsv_utils.common.utils.InputFieldReordering - A class that creates a reordered subset of fields from an input line. Used to operate on a subset of fields in the order specified on the command line.
• tsv_utils.common.utils.BufferedOutputRange - An OutputRange with an internal buffer used to buffer output. Intended for use with stdout, it is a significant performance benefit.
• tsv_utils.common.utils.bufferedByLine - An input range that reads from a File handle line by line. It is similar to standard library method std.stdio.File.byLine, but quite a bit faster. This is achieved by reading in larger blocks and buffering.
• tsv_utils.common.numerics.quantile - Calculates a cummulative probability for values in a data set. Supports the same interpolation methods as the quantile function in R and many other statistical packages.
• tsv_utils.common.numerics.rangeMedian - Finds the median in a range. Implements via the faster of std.algorithm.topN or std.algorithm.sort depending on the Phobos version.
• tsv_utils.common.numerics.formatNumber - An alternate print format for numbers, especially useful when doubles are being used to represent integer and float values.
• tsv_utils.common.getopt_inorder.getoptInorder - A cover for std.getopt that processes command line arguments in the order given on the command line.
