patchLog: Patch a LaTeX log file.

In patchDVI: Package to Patch '.dvi' or '.synctex' Files

Patch a LaTeX log file.

Description

This function parses a standard LaTeX log file and applies patches to it based on an Sweave concordance, so that error messages and warnings refer to the ‘.Rnw’ file rather than the ‘.tex’ file.

Usage

patchLog(f, newname = f, concords = NULL, max_print_line = 79, Cstyle = FALSE)

Arguments

f	The filename of the log file.
newname	The filename to write the patched file to.
concords	Concordances read from the ‘.dvi’ or ‘.pdf’. If NULL, an attempt is made to read these from the source.
max_print_line	The line length at which the latex compiler will wrap error messages.
Cstyle	If TRUE, only look for C-style error messages "filename:num: msg". If FALSE, look for classic messages "! msg". If NA, look for both, pick the more popular style.

Details

The parsing is based on the log parser written by Jonathan Kew, Stefan Löffler, Antonio Macrì, and Henrik Skov Midtiby for TeXWorks. That parser assumes error lines are reported in the standard format; C style errors are not currently supported. patchLog can detect C style errors, but standard format is assumed by default, and is preferred.

Value

This function is called mainly for the side effect of writing the new log file. It returns the concords object invisibly.
