NAME
jbofihe - Lojban parser / grammar checker / word glosser
SYNOPSIS
jbofihe [-v] [ -h | --help | -? ] [ -k ] [ -t ] [-tf ] [ -l ] [ -b ] [ -x ] [ -H ] [ -m ] [ -w width ]
[-ie] [-re] [-se] [-sev] [-cr] [-bt] [filename]
DESCRIPTION
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.
OPTIONS
-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 one child.
-l Produce output for typesetting with LaTeX.
-x Produce plain text output.
-w width
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 -h).
-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 assumed.
-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 failures).
-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 case.
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.
filename
The name of the file containing text to be parsed. If omitted, the text is read from standard
input.
EXIT STATUS
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 parsing algorithm.
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 determined.
SEE ALSO
cmafihe
A program which does English word glossing without the grammar parsing and checking stage. This
is useful to get words quickly looked up when studying someone else's text which contains many
grammatical errors.
smujajgau
A program for compiling binary dictionaries for use by jbofihe
FILES
/usr/local/lib/jbofihe/smujmaji.dat
This file contains all the dictionary data compiled (using smujajgau ) into a binary format to
facilitate lookup and search.
/usr/local/bin/jbofihe
The executable.
ENVIRONMENT
JBOFIHE_DICTIONARY
This should point to the name of the file containing the dictionary. The default is
/usr/local/lib/jbofihe/smujmaji.dat
