The extension is what drove the expectation. Example: extension .pdf expects PDF, got Text (LF) ``` - previously we had the ignore options like this ``` -I, --ignore-dupes Ignore dupes --ignore-same-named Ignore same-named files ``` now we have ``` -I, --ignore <IGNORE>... Comma-separated list of things to ignore: dupes, same-named, tmpfiles dupes: ignore duplicate files same-named: ignore same-named files tmpfiles: ignore temporary files [possible values: dupes, same-named, tmpfiles] ``` - detection of executable files (which implies 775 permissions) - we no longer check if a file is Lua bytecode, as Lua bytecode cannot directly be executed - issue W0008 regarding Unix line endings now issued only for Windows command files (`.bat` and `.cmd`) PowerShell files are now ignored, they may have CRLF or LF. - search for generated files improved (now using nom parser) - this was done together with Claude Sonnet (Anthropic) - switch from Makefile to justfile - crate updates - correct a bug where an LF line ending was added in case the last line of a text file didn't have any line ending - allow 555/444 perm for directories resp. files ---------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/support/pkgcheck More information is at https://www.ctan.org/pkg/pkgcheck ------------------------------------------------------------------------ Thanks for the upload.
