SS(1) SS(1) NAME SS - batch spreadsheet calculator SYNOPSIS SS [-h|--help] SS --version SS [-H|--HTML|--html] [-t|--title title] [-T|--Table|--table] [-p|-p2|--plot|--plot2d|-p3|--plot3D] [-x|--xlabel xlabel] [-y|--ylabel ylabel] [-z|--zlabel zlabel] [ss options...] [file...] ss [-d|--debug] [-v|--verbose] [-r|--rows #rows] [-c|--cols #cols] DESCRIPTION SS is a batch spreadsheet processor for C programmers. It produces a spreadsheet display from plain text input files, similar to the way documents are created using LaTeX. The resulting display is not inter‐ active. A shell script front-end is also provided for preprocessing (using the C preprocessor) and post-processing to generate HTML or graphics output. SS includes all of the numeric operators from the C programming lan‐ guage, with the same syntax, precedence, and associativity as C. It also includes all of the functions from the C90 (ANSI/ISO 9899:1990) standard library math.h, all of the non-complex functions from the C99 standard library tgmath.h, as well as other numeric and range func‐ tions. It allows cycles and non-convergent iterative formulas. OPTIONS -h or --help Displays usage summary to standard error and then exits. --version Displays version to standard output and then exits. -H or --HTML or --html Produces HTML output. -t title or --title title Sets the title for HTML or plot output. -T or --Table or --table Produces HTML table output without any , , or tags, suitable for embedding in an HTML document. -p or -p2 or --plot or --plot2d Produces 2D plot GIF output. -p3 or --plot3d Produces 3D plot GIF output. -x xlabel or --xlabel xlabel Sets the x axis label for plot output. -y ylabel or --ylabel ylabel Sets the y axis label for plot output. -z zlabel or --zlabel zlabel Sets the z axis label for plot output. -d or --debug Turns on debugging of the flex scanner and bison parser. -v or --verbose Displays the row and column index ranges. -r #rows or --rows #rows Sets the number of rows (default 1000). -c #cols or --cols #cols Sets the number of columns (default 702). file... Reads input from files, or from standard input if no file names are specified. The pseudo input file name "-" can also be used to explicitly specify reading standard input. All of the input is filtered through the C preprocessor.
