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 ID s 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 ID s 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 ID s 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 , respectively. 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 ID s. The results are printed in their order of occurrence in the respective LOG-FILE s. Pipe the output into sort to get alphabetically ordered ID s.

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 ID s. 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 ID s 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 ID s with option --id : Inline (0) or heading before the matching data (1). Default: 0.

"id-heading-format"= FORMAT

Control the FORMAT for printing matching ID s in heading-mode, where FORMAT is passed to Perl’s "printf". Default: "--> %s <--".

"id-indent"= INDENT

Indentation of nested typog-inspect tags. Only used in ‘‘discovery mode’’ (first form), i.e., if --all is active. Default: 8.

"id-max-length"= MAXIMUM-LENGTH

Set the maximum length of a matching ID for printing. It a matching ID exceeds this length it will be truncated and the last three characters (short of MAXIMUM-LENGTH ) will be replaced by dots. Default: 40.

"line-number-format"= FORMAT

Control the FORMAT for printing TeX source line numbers, where FORMAT is passed to Perl’s "printf". Default: %5d.

"log-line-number-format"= FORMAT

Control the FORMAT for printing log line numbers, where FORMAT is passed to Perl’s "printf". Default: %6d.

"page-number-format"= FORMAT

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.
