srcredact — a program for redaction of text files


srcredact [Options] -e audience [full_file]

srcredact [Options] -u audience full_file [redacted_file]

srcredact -l [full_file]

srcredact -h|-v


srcredact is the program to extract “redacted versions” of the master file (option -e) or to incorporate the changes in the redacted versions into the master file (“unredact”, option -u).

The master file consists of chunks intended for different audiences.  Each audience has a name, e.g. "classified", "unclssified", "expert" etc.  Chunks are started and stopped by guard lines.  Each guard line has the format (for the default TeX syntax)




In the first cases the text following the guard is included for the audiences "name1", "name2", ....  In the second case it is excluded for these audiences.

THere is a special audience "ALL": a wild card for all audiences. Thus the idiom


means that the chunk is excluded for all audiences but "classified"

Exactly one of the options  -e (extract) or -u (unextract) must be present.  In  the extract mode the  non-option argument is  the name of the full file.   If it is absent, or is "-",  standard input is used. In the unextract mode the first non-option argument


-c list of comment patterns

Use the given pattern for comment lines to search for guards instead of the default "TeX" pattern.  The recognized patterns are:


The pattern names should be separated by commas, and the list may be enclosed in quotes to prevent shell expansion, e.g

  -c "TeX, c, shell"

Debug mode on.

-e audience

Extract the contents for the current audience into the file file. The cuurent audience is guessed from the file name, if the latter has the structure base-audience.extension, e.g. "report-unclassified.tex".  The key -a overrides this guess and should be used if the file name does not follow this pattern.  The file name "-" means the standard output.


Print help information and exit.


List all audiences set in the file (one per line) and exit.

-u audience

Take a edited file intended for the audience (the second non-option argument) and incorporate the changes in it into the full file (the first non-option argument).  If the second argument is missing, standard input is used instead.  As usual, "-" also means standard input.  Note that only one of the two file arguments in this case can be standard input.


Print version information and exit.

-w on|off|1|0|true|false

If "on", 1 or "true" (the deafult), implicitly wrap the full document into the guards


Return Value

The program returns 0 if successful, 1 if conflicts were found in the "unextract" mode and 2 in case of problems.

Conflicts in Unextract Mode

Like the standard diff3(1) tool, the program may find conflicts between the full version and the edited one in the -u mode.  Then the resulting file brackets the conflicts in the usual manner, e.g.

  <<<<<<< /tmp/BrjXo0hMOB/full
  Forty-five tons best old dry government bonds, suitable for furnace, gold
  7 per cents., 1864, preferred.
  ||||||| /tmp/BrjXo0hMOB/extracted
  Forty-five tons best old dry government bonds, suitable for furnace, gold
  7 per cents., 1864, preferred.
  >>>>>>> /tmp/BrjXo0hMOB/new

Here "full" is the full document, "extracted" is the extracted file for the given audience, "new" is the edited file.
