Software

The Lojban website now has a Lobjan To English Translation Program.
The Lojban dictionary project, jbovlaste, is now in full swing. There are complete or near-complete dictionaries for Spanish, Esperanto, and English, and the Lojban-in-Lojban dictionary is progressing rapidly.

This directory contains the following programs:

analyser: The source code (in Prolog) for Nick Nicholas's Lojban Semantic Analyser.
brkwords.exe: An implementation of the Lojban word-resolution algorithm, which is described in brkwords.txt. The source for this program is in brkwords.pas.
gloss3-2.zip: The Lojban Parser/Glosser. This program takes grammatical Lojban text and translates it word for word into an English gloss, including identifying case tags for the sumti of all gismu that are used. The file includes the up to date Lojban parser.
lujvomak.zip: The Lojban lujvo-making and analysis program. This program allows you to make lujvo given the source metaphor (English keywords) or to analyze a lujvo into its component metaphor. There are drill modes that generate random lujvo to test your word making and analysis skills.
rndsen28.zip: This is an obsolete version of the Lojban random sentence generator, based on the 2.8 version of the grammar. A new version is being worked on. Most of the sentences that this program generates will be correct Lojban.
scrabble.zip: This is an attempt to make a Lojban compatible version of the Scrabble (tm) word game. Letter frequencies are based on frequencies in Lojban words.
gunzip.exe: The GUNZIP program, used to uncompress .gz files.

Logflash files

flashdoc.txt: Internal program documentation, somewhat out of date, for LogFlash. Probably useful to anyone trying to modify the source.
flashman.txt: A description of the flashcard management process used as the basis for LogFlash - essentially an algorithm statement for the program.
lfsrc.zip: The Turbo-Pascal source for the current version of LogFlash 1 (LF3 differs only in changing some constant parameters).
logflash.zip: LogFlash, a computer-aided instruction program for teaching Lojban gismu. This is an MS-DOS executable with support files.
logfl3.zip: LogFlash 3, a computer-aided instruction program for teaching Lojban cmavo. This is an MS-DOS executable with support files.
logflash.txt: A description of the LogFlash algorithm at the user level. The current version is described. LogFlash 2,mentioned in the text, is being brought up to the current language standard, but is not yet available.

software/parser:

The files in this directory are the current distribution of the LLG official Lojban parser, in source form and MS-DOS executable.

Basically, there are two files. parser.zip contains the MS-DOS executable, whereas parser.shar.gz contains the source code. To compile the parser from the source code, just say "cc -o parser *.c"; there is no Makefile. The code is in K&R C, but should compile all right using an ANSI compiler. If you have trouble unpacking the ZIP file, use PKZipFix to convert it to MS-DOS ZIP format.

Both versions contain the 'yacc' grammar, the current E-BNF grammar, and a list of technical fixes updating the 2nd baseline grammar. You can process the 'yacc' version with yacc or bison, but do not attempt to use the resulting y.tab.c file in the parser -- the provided grammar.c has been extensively hacked both before and after 'yacc'ing to make it work in the parser.
