jbofihe is a program that reads a piece of Lojban text and checks it
for grammatical correctness. If it passes, the output will show the
nesting of the major grammatical constructs by means of bracketing.
Also, words will have their approximate English translations shown.
Some of these translations are context-dependent.
-v Show the program version and exit.
-h Show help page
--help Show help page
-? Show help page
-k Display lists of tokens after parse and after pseudo-token
insertion (mainly useful for debugging the lexer and parser).
-t Produce a syntax tree on stdout. Nodes with only one child will
be filtered out.
-tf Produce a full syntax tree on stdout, including nodes with only
-l Produce output for typesetting with LaTeX.
-x Produce plain text output.
Set the width of the screen (in characters) for the -x option.
-H Produce HTML output
-b Produce output in ’block’ mode, where each block shows the
Lojban, the English gloss and a term tag where applicable. The
default is the same line. Only applicable to -l and -x (not to
-m Show the amount of memory used by the processing.
-ie Display elided separators and terminators in the output. They
are shown in upper case, to distinguish them from those
originally present in the input text.
-re Require the input text to have all elidable cmavo actually
present. (May be useful for forcing the user to think about the
grammatical structure of the input text more carefully when
debugging parse errors.)
-se Show any elidable cmavo that were present unnecessarily in the
input text. Where a sequence of elidable cmavo occur, but not
all could have been elided, a list of possible ’minimal’
sequences is shown. Each ’minimal’ sequence is such that :
removing any words from it would cause the meaning of the text
to change (or make it ungrammatical); yet preserving any more of
the original words is unnecessary to preserve the meaning and
grammatical correctness of the text. Note, -se and -re are
mutually incompatible. If both switches are specified, -re is
-sev For each sequence of elidable cmavo, show where later ones could
be valid before earlier ones, and where the non-elidable word at
the end of the sequence could have been valid earlier in the
sequence. [This information is used to determine the output of
-se, so this is a verbose mode for -se].
-cr Allow lujvo to contain the cultural rafsi forms CCVVCy (CCVVCV
at end of word) described in section 4.16 of the Reference
Grammar. This affects recognition of valid lujvo and fu’ivla
forms (the latter since it affects the recognition of slinku’i
-bt Show backtrace through the pending parser states when a syntax
error occurs. This may give some insight into what the parser
was expecting to see next, to help in fixing the error.
The backtrace comes in three parts. The first part is a list of
rules which are automatically reduced when the erroneous word is
encountered. In the extreme case, when everything prior to the
erroneous word constitutes a complete text in its own right, the
reduction sequence will go right the way to the rule which
matches a complete text. Generally though, this will not be the
The second part of the report shows the conditions where the
grammar requires the next word to be of a type other than that
which actually appeared. All the active rules are shown (with
periods showing the active points), followed by a list of word
classes (i.e. selma’o or BRIVLA/CMENE etc) that would have been
valid at this point.
The third part of the report shows the pending states on the
parser stack. This may give some information on whereabouts at
a wider level the problem situation has occurred.
The name of the file containing text to be parsed. If omitted,
the text is read from standard input.
0 The text was scanned and parsed successfully - the text was
grammatically valid Lojban.
1/2 The text had grammatical errors that were detected by the main
3 The text contained words whose structure was not valid Lojban.
No grammatical checking of the text was performed; the
grammatical function of the erroneous word(s) could not be
A program which does English word glossing without the grammar
parsing and checking stage. This is useful to get words quickly

A program for compiling binary dictionaries for use by jbofihe
This file contains all the dictionary data compiled (using
smujajgau ) into a binary format to facilitate lookup and
This should point to the name of the file containing the
dictionary. The default is /usr/local/lib/jbofihe/smujmaji.dat
