NAME

       typog-grep - specialized grep for typog-inspect elements in LaTeX log files

SYNOPSIS

       typog-grep -a|--all|--any [OPTION...] LOG-FILE...
       typog-grep [OPTION...] REGEXP LOG-FILE...

       The first form, ``discovery mode'', shows all IDs of
              <typog-inspect id="ID" ...>

       elements in LOG-FILE.

       The second form shows the contents, LOG-DATA, of the elements
              <typog-inspect id="ID" ...>
              LOG-DATA
              </typog-inspect>

       whose IDs match REGEXP in LOG-FILE.

       If no LOG-FILE is given read from stdin.  The filename "-" is synonymous to stdin.

DESCRIPTION

       typog-grep is a tailored post-processor for LaTeX log files and the "typoginspect" environment as
       provided by the LaTeX package typog.  It shares more with the venerable sgrep
       <https://www.cs.helsinki.fi/u/jjaakkol/sgrep.html> than with
       POSIX grep <https://pubs.opengroup.org/onlinepubs/9699919799/utilities/grep.html>.

       In the LaTeX source file the user brackets her text or code in a "typoginspect" environment:
              \begin{typoginspect}{ID}
              TEXT-OR-CODE-TO-INVESTIGATE
              \end{typoginspect}

       where ID is used to identify one or more bracketed snippets.  ID does not have to be unique.  The REGEXP
       mechanism makes it easy to select groups of related IDs if they are named accordingly.

       In LOG-FILE the result of the environment shows up, packed with tracing information, as
              <typog-inspect id="ID" job="JOB-NAME" line="LINE-NUMBER" page="PAGE-NUMBER">
              LOG-DATA
              </typog-inspect>

       where all the capital-letter sequences are meta-variables and in particular JOB-NAME is the expansion of
       "\jobname", LINE-NUMBER is the LaTeX source file line number of the beginning of the "typoginspect"
       environment, and PAGE-NUMBER is the page where the output of "TEXT-OR-CODE-TO-INVESTIGATE" occurs.

       typog-grep reveals the contents of LOG-FILE between "<typog-inspect id="ID" ...>" and "</typog-inspect>"
       excluding the XML-tags themselves.  Access the JOB-NAME, LINE-NUMBER, and PAGE-NUMBER with the
       commandline options --job-name, --line-number, and --page-number.  Use --id to show the name of the IDs
       that matched REGEXP.

       "typoginspect" environments can be nested.  typog-grep respects the nesting, i.e., if the ID of the
       nested environment does not match REGEXP it will not be included in the program's output.

OPTIONS

The list of options is sorted by the names of the long options.

-a, --all, --any
ID-discovery mode: Discover all "typog-inspect" elements independent of any matching patterns and
print their IDs. The results are printed in their order of occurrence in the LOG-FILEs. Pipe the
output into sort to get alphabetically ordered IDs.

Augment with options --job-name, --line-number, --log-line-number, or --page-number for more
information.

--color, colour WHEN
Colorize specific log contents for the matching IDs. The argument WHEN determines when to apply
color: "always", "never", or "auto". The setting "auto" checks whether standard output has been
redirected. This is the default.

-C, --config KEY=VALUE[:KEY=VALUE[:...]]
Set one or more configuration KEY to VALUE pairs. See section "CONFIGURATION" for a description of
all available configuration items. Use option --show-config to display the default configuration.

--debug
Turn on debug output on stderr.

-E, --encoding ENCODING
Set the ENCODING of LOG-FILE for the translation to UTF-8. The default is unset.

Use this option to get rid of pesky "<HEX-DIGITS>" escapes on UTF-8 terminals. See
option --show-encodings for the known encodings and Encode::Supported for a summary of all encodings.
See also section "Some Common Encodings".

Apply iconv <https://pubs.opengroup.org/onlinepubs/9699919799/utilities/iconv.html> (POSIX) or recode
<https://github.com/rrthomas/recode/> (GNU) on LOG-FILE before this tool to avoid having to use
option --encoding.

-h, --help
Display brief help then exit.

-i, --[no-]id
Print the actual ID-name that matched REGEXP. Control the appearance of the matching ID with
configuration item "id-heading".

-y, --[no-]ignore-case
Match IDs while ignoring case distinctions in patterns and data.

-j, --[no-]job-name
Print the "\jobname" that latex associated with the input file.

-n, --[no-]line-number
Print the line number where the "typoginspect" environment was encountered in the LaTeX source file.

-N, --[no-]log-line-number
Print the line number of the log-file where the current line was encountered.

-p, --[no-]page-number
Print page number where the contents of the "typoginspect" environment starts in the typeset
document.

-P, --[no-]pager
Redirect output from stdout to the configured pager.

--show-config
Show the default configuration and exit.

--show-encodings
Show all known encodings and exit.

-V, --version
Show version information and exit.

-w, --[no-]word-regexp
Match only whole words.

CONFIGURATION

       "id-format"=FORMAT
           Control the FORMAT for printing matching ids in inline-mode, where FORMAT is passed to Perl's
           "printf".  Default: %s:.

       "id-heading"=0|1
           Choose between printing the matching IDs with option --id: Inline (0) or heading before the matching
           data (1).  Default: 0.

       "id-heading-format"=FORMAT
           Control the FORMAT for printing matching IDs in heading-mode, where FORMAT is passed to Perl's

EXIT STATUS

       The exit status is 0 if at least one ID matched REGEXP, 1 if no ID matched REGEXP, and 2 if an error
       occurred.

CAVEATS

       The end tag "</typog-inspect>" sometimes gets placed too early in the output and the trace seems
       truncated.  However, LaTeX reliably logs the requested the trace information, but the write operations
       for trace data and the code which is used to print the end tag are not synchronized.
