srcredact(1) a program for redaction of text files

SYNOPSIS

srcredact [OPTIONS] -e audience [full_file]

srcredact [OPTIONS] -u audience full_file [redacted_file]

srcredact -l [full_file]

srcredact -h|-v

DESCRIPTION

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) 

  %<*name1|name2|...>

or 

  %</name1|name2|...>

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 

  %</ALL>
  %<*classified>

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

OPTIONS

-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:
c
  /*<guard>*/
cpp
  //<guard>
fortran
  C<guard>
shell
  #<guard>
TeX
  %<guard>

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"
-d
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.
-h
Print help information and exit.
-l
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.
-v
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 

 %<*ALL>
 ...
 %</ALL>

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
  %</nobonds>
  Forty-five tons best old dry government bonds, suitable for furnace, gold
  7 per cents., 1864, preferred.
  %<*nobonds>
  ||||||| /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.
