This is the general form of the command for parsing a bibliography\&. Depending on the options used to invoke it it will either return a token for the parser, or the parsed entries of the input bibliography\&. Instead of performing an immediate parse returning a predefined format the command can also enter an event-based parsing style where all relevant entries in the input are reported through callback commands, in the style of SAX\&. .TP \fB::bibtex::parse\fR \fItext\fR In this form the command will assume that the specified \fItext\fR is a bibliography in BibTeX format, parse it, and then return a list containing one element per record found in the bibliography\&. Note that comments, string definitions, preambles, etc\&. will not show up in the result\&. Each element will be a list containing record type, bibliography key and record data, in this order\&. The record data will be a dictionary, its keys the keys of the record, with the associated values\&. .TP \fB::bibtex::parse\fR ?\fB-command\fR \fIcmd\fR? \fB-channel\fR \fIchan\fR In this form the command will reads the bibliography from the specified Tcl channel \fIchan\fR and then returns the same data structure as described above\&. .sp If however the option \fB-command\fR is specified the result will be a handle for the parser instead and all processing will be incremental and happen in the background\&. When the input has been exhausted the callback \fIcmd\fR will be invoked with the result of the parse\&. The exact definition for the callback is .sp .RS .TP \fBcmd\fR \fItoken\fR \fIparseresult\fR The parse result will have the structure explained above, for the simpler forms of the parser\&. .RE .sp \fINote\fR that the parser will \fInot\fR close the channel after it has exhausted it\&. This is still the responsibility of the user of the parser\&. .TP \fB::bibtex::parse\fR ?\fB-recordcommand\fR \fIrecordcmd\fR? ?\fB-preamblecommand\fR \fIpreamblecmd\fR? ?\fB-stringcommand\fR \fIstringcmd\fR? ?\fB-commentcommand\fR \fIcommentcmd\fR? ?\fB-progresscommand\fR \fIprogresscmd\fR? ?\fB-casesensitivestrings\fR \fIbool\fR? (\fItext\fR | \fB-channel\fR \fIchan\fR) This is the most low-level form for the parser\&. The returned result will be a handle for the parser\&. During processing it will invoke the invoke the specified callback commands for each type of data found in the bibliography\&. .sp The processing will be incremental and happen in the background if, and only if a Tcl channel \fIchan\fR is specified\&. For a \fItext\fR the processing will happen immediately and all callbacks will be invoked before the command itself returns\&. .sp The callbacks, i\&.e\&. \fI*cmd\fR, are all command prefixes and will be invoked with additional arguments appended to them\&. The meaning of the arguments depends on the callback and is explained below\&. The first argument will however always be the handle of the parser invoking the callback\&. .RS .TP \fB-casesensitivestrings\fR This option takes a boolean value\&. When set string macro processing becomes case-sensitive\&. The default is case-insensitive string macro processing\&. .TP \fBrecordcmd\fR \fItoken\fR \fItype\fR \fIkey\fR \fIrecorddict\fR This callback is invoked whenever the parser detects a bibliography record in the input\&. Its arguments are the record type, the bibliography key for the record, and a dictionary containing the keys and values describing the record\&. Any string macros known to the parser have already been expanded\&. .TP \fBpreamblecmd\fR \fItoken\fR \fIpreambletext\fR This callback is invoked whenever the parser detects an @preamble block in the input\&. The only additional argument is the text found in the preamble block\&. By default such entries are ignored\&. .TP \fBstringcmd\fR \fItoken\fR \fIstringdict\fR This callback is invoked whenever the parser detects an @string-based macro definition in the input\&. The argument is a dictionary with the macro names as keys and their replacement strings as values\&. By default such definitions are added to the parser state for use in future bibliography records\&. .TP \fBcommentcmd\fR \fItoken\fR \fIcommenttext\fR This callback is invoked whenever the parser detects a comment in the input\&. The only additional argument is the comment text\&. By default such entries are ignored\&. .TP \fBprogresscmd\fR \fItoken\fR \fIpercent\fR This callback is invoked during processing to tell the user about the progress which has been made\&. Its argument is the percentage of data processed, as integer number between \fB0\fR and \fB100\fR\&. In the case of incremental processing the perecentage will always be \fB-1\fR as the total number of entries is not known beforehand\&. .RE .sp .TP \fB::bibtex::wait\fR \fItoken\fR This command waits for the parser represented by the \fItoken\fR to complete and then returns\&. The returned result is the empty string\&. .TP \fB::bibtex::destroy\fR \fItoken\fR This command cleans up all internal state associated with the parser represented by the handle \fItoken\fR, effectively destroying it\&. This command can be called from within the parser callbacks to terminate processing\&. .TP \fB::bibtex::addStrings\fR \fItoken\fR \fIstringdict\fR This command adds the macro definitions stored in the dictionary \fIstringdict\fR to the parser represented by the handle \fItoken\fR\&. .sp The dictionary keys are the macro names and the values their replacement strings\&. This command has the correct signature for use as a \fB-stringcommand\fR callback in an invokation of the command \fB::bibtex::parse\fR\&. .PP .SH "BUGS, IDEAS, FEEDBACK" This document, and the package it describes, will undoubtedly contain bugs and other problems\&. Please report such in the category \fIbibtex\fR of the \fITcllib Trackers\fR [http://core\&.tcl\&.tk/tcllib/reportlist]\&. Please also report any ideas for enhancements you may have for either package and/or documentation\&. .PP When proposing code changes, please provide \fIunified diffs\fR, i\&.e the output of \fBdiff -u\fR\&. .PP Note further that \fIattachments\fR are strongly preferred over inlined patches\&. Attachments can be made by going to the \fBEdit\fR form of the ticket immediately after its creation, and then using the left-most button in the secondary navigation bar\&. .SH KEYWORDS bibliography, bibtex, parsing, text processing .SH CATEGORY Text processing .SH COPYRIGHT .nf Copyright (c) 2005 for documentation, Andreas Kupries .fi
