Bug Tracker

I’m currently working on a major new version of the datatool package. This may take a while. Please be patient. (Experimental version available for testing.)

ID	183🔗
Submitted by:	Nicola Talbot 🦜

Status	Closed (Fixed)
Category	makeglossaries-lite (Lua)
Version	4.45
Summary	"bad argument #1 to 'gsub'" when `\makeglossaries` missing
OS	Linux
Interpreter Version	1.13.2

Description

If \makeglossaries is missing, makeglossaries-lite is supposed to warn the user but instead generates the following error:

makeglossaries-lite:385: bad argument #1 to 'gsub' (string expected, got nil)

This stems from the second of the following two lines:

styfile = string.match(aux, "\\@istfilename{([^}]*)}")
styfile = string.gsub(styfile, "\"", "");

If \@istfilename is missing from the aux file then styfile ends up nil from match, which causes an error from gsub.

The code needs to be modified to test for styfile ~= nil:

  if styfile ~= nil
  then
    styfile = string.gsub(styfile, "\"", "");
  end
