The indentation stripping semantics of strings are fairly bad and have a few gotchas where the resulting string has not the intended indentation. This commit fixes most if not all such instances in Nixpkgs. I tried to strive a balance between keeping the diff small and reformatting/refactoring the code to look better. In general, reformatting should be left to Nixfmt. Note that this causes a lot of rebuilds by design. All changes need to be thoroughly vetted and reviewed for correctness. There is no automatic way to prove correctness. List of files to fix generated by running https://gerrit.lix.systems/c/lix/+/2092 on Nixpkgs and looking at the warnings.

|
|
GNU libextractor is a library used to extract meta-data from files
|
|
of arbitrary type. It is designed to use helper-libraries to perform
|
|
the actual extraction, and to be trivially extendable by linking
|
|
against external extractors for additional file types.
|
|
|
|
The goal is to provide developers of file-sharing networks or
|
|
WWW-indexing bots with a universal library to obtain simple keywords
|
|
to match against queries. libextractor contains a shell-command
|
|
extract that, similar to the well-known file command, can extract
|
|
meta-data from a file an print the results to stdout.
|
|
|
|
Currently, libextractor supports the following formats: HTML, PDF,
|
|
PS, OLE2 (DOC, XLS, PPT), OpenOffice (sxw), StarOffice (sdw), DVI,
|
|
MAN, FLAC, MP3 (ID3v1 and ID3v2), NSF(E) (NES music), SID (C64
|
|
music), OGG, WAV, EXIV2, JPEG, GIF, PNG, TIFF, DEB, RPM, TAR(.GZ),
|
|
ZIP, ELF, S3M (Scream Tracker 3), XM (eXtended Module), IT (Impulse
|
|
Tracker), FLV, REAL, RIFF (AVI), MPEG, QT and ASF. Also, various
|
|
additional MIME types are detected.
