In Vim, you can type :%!xxd to turn it into a hex editor. :%!xxd -r to go back to normal mode. xxd is shipped in a Vim installation. See here for some remarks about editing binary files with Vim (it boils down to :set binary to avoid trouble. Use only the “R” or “r” command … Read more
Git can usually detect binary files automatically. No, Git will attempt to store delta-based changesets if it’s less expensive to (not always the case). Submodules are used if you want to reference other Git repositories within your project.
You can use the file command. It does a bunch of tests on the file (man file) to decide if it’s binary or text. You can look at/borrow its source code if you need to do that from C. file README README: ASCII English text, with very long lines file /bin/bash /bin/bash: ELF 32-bit LSB … Read more
Subversion has locks, and they aren’t just advisory. They can be enforced using the svn:needs-lock attribute (but can also be deliberately broken if necessary). It’s the right solution for managing non-mergeable files. The company I work for stores just about everything in Subversion, and uses svn:needs-lock for all non-mergeable files. I disagree with “locks are … Read more
Kind of cheating but here’s what I used: diff -r dir1/ dir2/ | sed ‘/Binary\ files\ /d’ >outputfile This recursively compares dir1 to dir2, sed removes the lines for binary files(begins with “Binary files “), then it’s redirected to the outputfile.
When testing for performance, I would include a test case for: std::vector<BYTE> readFile(const char* filename) { // open the file: std::ifstream file(filename, std::ios::binary); // Stop eating new lines in binary mode!!! file.unsetf(std::ios::skipws); // get its size: std::streampos fileSize; file.seekg(0, std::ios::end); fileSize = file.tellg(); file.seekg(0, std::ios::beg); // reserve capacity std::vector<BYTE> vec; vec.reserve(fileSize); // read the data: … Read more
As @user786653 suggested, use the xxd(1) program: xxd -r -p input.txt output.bin
OK, after a lot of digging, I found out that requestSettings should have: encoding: null And then body will be of type Buffer, instead of the default, which is string.
I generally store files on the file-system, since that’s what its there for, though there are exceptions. For files, the file-system is the most flexible and performant solution (usually). There are a few problems with storing files on a database – files are generally much larger than your average row – result-sets containing many large … Read more
Menu File → Open → File Select the file to be opened On the open file dialog at the bottom there is a down arrow on the “Open” button Click “Open With…” Click “Binary Editor” Click OK Or for the keyboard geeks out there: Ctrl + o Ctrl + v (paste filename) tab tab ↓ … Read more
