NAME

server, client, image, meta, merge — collaborative ASCII art

SYNOPSIS

server

[-d data] [-p pidfile] [-s sock]

client

[-h] [-s sock]

image

[-k] [-d data] [-f font] [-x x] [-y y]

meta

merge

data1 data2 data3

DESCRIPTION

server maps a data file and listens on a UNIX-domain socket to synchronize events between clients.

client connects to a UNIX-domain socket and presents a curses(3) interface.

image renders a tile from a data file using a PSF2 font to PNG on standard output. To build with kcgi(3) support, copy kcgi.mk to config.mk.

meta extracts metadata from a data file on standard input to CSV on standard ouput. The CSV fields are tileX, tileY, createTime, modifyCount, modifyTime, accessCount, accessTime.

merge interactively merges two data files data1 and data2 into data3. data1 and data2 may be compressed with gzip(1). Differing tiles are presented in a curses(3) interface and are chosen by typing a or b.

The arguments are as follows:

-d data

Set path to data file. The default path is torus.dat.

-f font

Set path to PSF2 font. The default path is default8x16.psfu.

-h

Write help page data to standard output and exit.

-k

Run a FastCGI worker for use with kfcgi(8).

-p pidfile

Daemonize and write PID to pidfile.

-s sock

Set path to UNIX-domain socket. The default path is torus.sock.

-x x

Set tile X coordinate to render.

-y y

Set tile Y coordinate to render.

IMPLEMENTATION NOTES

help.h contains tile data for the help page and can be generated from the first tile of torus.dat.

default8x16.psfu is taken from kbd.
