From 0d806799aaef65b12a9b75e8c49c2613c68d5ac2 Mon Sep 17 00:00:00 2001 From: Juergen Spitzmueller Date: Sat, 17 Feb 2018 11:25:28 +0100 Subject: [PATCH] Adapt to new ChkTeX return values. As of v. 1.7.7, chktex has four exit values. Only consider the program failed with EXIT_FAILURE (1). This is backwards compatible to chktex up to v. 1.7.5 and later patched versions included in TeXLive, where there was the distinction EXIT_FAILURE (program failed) and EXIT_SUCCESS (program successfully run, with or without something to report). Note that ChkTeX v. 1.7.5 and 1.7.6 vanilla (as included in MikTeX) also returned EXITE_FAILURE if ChkTeX found something to report. We do not, and never did, support this case. Fixes: #9989 (after ChkTeX 1.7.7. is released). --- src/Chktex.cpp | 16 +++++++++++----- 1 file changed, 11 insertions(+), 5 deletions(-) diff --git a/src/Chktex.cpp b/src/Chktex.cpp index 816837a025..ac4599ddd0 100644 --- a/src/Chktex.cpp +++ b/src/Chktex.cpp @@ -34,16 +34,22 @@ Chktex::Chktex(string const & chktex, string const & f, string const & p) int Chktex::run(TeXErrors &terr) { - // run bibtex + // run chktex string log = onlyFileName(changeExtension(file, ".log")); string tmp = cmd + " -q -v0 -b0 -x " + file + " -o " + log; Systemcall one; int result = one.startscript(Systemcall::Wait, tmp); - if (result == 0) { - result = scanLogFile(terr); - } else { + // ChkTeX (as of v. 1.7.7) has the following return values: + // 0 = EXIT_SUCCESS : program run successfully, nothing to report + // 1 = EXIT_FAILURE : program run unsucessfully + // 2 = EXIT_WARNINGS : program run successfully, only warnings to report + // 3 = EXIT_ERRORS : program run successfully, errors to report + // We only check for EXIT_FAILURE here, since older versions of ChkTeX + // returned 0 also in case 2 and 3. + if (result == EXIT_FAILURE) result = -1; - } + else + result = scanLogFile(terr); return result; } -- 2.39.5
