Check latexmk logs for common errors

check_log.Rd

Uses regular expressions to search log files for common errors:

Usage

check_log(slide_file, before = 0, after = 1)

Arguments

slide_file

[character(1)] Name of a (single) slide, with or without .tex extension. See examples of find_slide_tex(). Can also be a direct file path to enable use of this function outside rigid folder hierarchy.

before, after

[integer(1)] Number of log lines to display before and after the line found via regex. Defaults to 0 lines before, 1 line after.

Value

A character vector with one element per match, with individual lines separated by \\n within each element. If no errors are detected, an empty character(0) is returned.

Details

  • "^! Undefined control sequence": Typo, missing package or preamble (including latex-math), or command not defined.

  • "not found": Implying a missing figure or other included file, maybe due to misspecified filename via Overleafs autocompletion (slides/<topic>/figure/ path instead of figure/) or file not committed to git.

  • "^! Missing $ inserted": Missing $ delimiter for math

  • "! LaTeX Error:": A generic error

  • Runaway argument: Often caused by missing closing parantheses.

Examples

if (FALSE) { # \dontrun{
# Example where compilation failed due to simple typo / syntax error:
check_log("slides-gp-basic-3")
# "976: ! Undefined control sequence.\n976: l.9 \newcommandiscrete\n"
} # }
