The Ascii2Binary project consists of two complementary programs that convert between textual and binary representations of numbers. Ascii2Binary reads input consisting of textual representations of numbers separated by whitespace and produces as output the binary equivalents. It is useful for generating test data and linking programs that generate textual output to programs that require binary input. Binary2Ascii converts binary numbers to text. In both programs, the type and size/precision of the input or output is selected using command line flags.
AudioSpace calculates the amount of storage required by an audio recording of a given duration, for different sampling rates, resolutions, and numbers of channels. The calculation may be made for uncompressed audio data or for several types of compression. A variety of units may be selected for reporting the result. The calculation may also be inverted to determine the maximum duration of audio that will fit into the available storage.
ByteName is a tool that for each byte of the input prints a line consisting of the byte offset, the byte in hex, octal, binary, and decimal, and its description in a selected single-byte encoding. A command line flag suppresses printing of lines corresponding to ASCII characters, which is useful for locating stray non-ASCII codes. It can also generate a chart for a specified encoding or, for a specified codepoint, generate descriptions in all known encodings.
CharEntry is a tool for inserting non-ASCII characters into text, with particular emphasis on linguistic notation. It provides charts of the consonants, vowels, and diacritics of the International Phonetic Alphabet as well as a chart of precomposed accented characters. Clicking on a character inserts it into a text region, the contents of which may be saved to a file or copied and pasted elsewhere. A widget for inserting characters by Unicode codepoint is also provided. Furthermore, it is possible to read the definition of a custom character chart from a file.
ColorExplorer is a tool for exploring the color space and finding out how colors, color names, and numerical color specifications are related. The user can specify a color by selecting its name from a list of color names, by adjusting sliders that control the mixture of red, green, and blue, by entering a numerical color specification, by copying it from the history list or elsewhere on the display, or by requesting a random color. The numerical specification of the current color and an example of that color are shown in a pair of adjacent boxes. The color name list may be searched by entering a regular expression or by requesting the closest match to the current color.
ISCII Utilities is two programs for analyzing text files encoded according to the Indian Script Code for Information Interchange (ISCII), the Indian national standard. IsciiName identifies each code, printing the byte offset, the code in hex, and an explanation of the meaning of the code. ATR codes for writing system transition and display mode are interpreted. CountIsciiChars counts the codes in an ISCII file and classifies them according to their type and function. The original purpose was computing accurate letter counts for reading studies, but this information is also useful when processing ISCII-encoded text.
libuninum is a library for converting Unicode strings to integers and integers to Unicode strings. Internal computation is done using arbitrary precision arithmetic, so there is no limit on the size of the integer that can be converted. Values are passed and returned as ASCII decimal strings, GNU MP mpz_t objects, or unsigned long integers. Auto-detection of the number system is provided. Very many number systems are supported. Group delimitation for output strings is fully controllable. Command line and graphical interfaces are also provided.
Minpair consists of two programs, a C command-line program and a Tcl/Tk GUI, each of which can independently generate a complete list of minimal pairs (words differing in exactly one segment) for use in linguistic research. The GUI may also be used to control the faster CLI program. Both allow sequences of characters to be defined as single segments. Unicode is fully supported. It is also possible to obtain a list of pairs differing in exactly two positions for use in finding phonological rules.
Msort sorts files in sophisticated ways. Records may be fixed size, newline-separated blocks, or terminated by any specified character. Key fields may be selected by position, tag, or character range. For each key, distinct exclusions, multigraphs, substitutions, and a sort order may be defined or locale collation rules used. Comparisons may be lexicographic, numeric, numeric string, hybrid, random, by string length, angle, domain name, date, time, month name, or ISO8601 timestamp. Keys may be reversed so as to generate reverse dictionaries. Optional keys are supported. Unicode is supported, including full case-folding. Msort itself has a somewhat complex command line interface, but may be driven by an optional GUI.
Pause determines the location of silences in an audio file for use in fragmentation of large recordings, studies of pause duration, and the like. It generates both a nicely formatted table intended to be read by people and a simple tab-delimited file that is easily parsed by software.
What's with the fixed width pages? I hate being forced either to scroll horizontally or use a really wide window.
interesting - somewhat like pic This is interesting and looks promising. It looks rather like a development of pic.
comparison How does BigMath compare to other similar libraries such as GNU MP? Any particular advantages?
