search for: filename_

Dear list memebers, I am stuck with using regular expressions. Imagine I have a vector of character strings like: test <- c('filename_1_def.pdf', 'filename_2_abc.pdf') How could I use regexpressions to extract only the 'def'/'abc' parts of these strings? Some try from my side yielded no results: testresults <- grep('(?<=filename_[[:digit:]]_).{1,3}(?=.pdf)', perl = TRUE, value = TRUE)...

I have a list of suffixes I want to turn into file names with extensions. suff<- c("C1", "C2", "C3") paste("filename_", suff[[1]], ".ext", sep="") [1] "filename_C1.ext" How do I use lapply() on that call to paste()? What's the right way to do this: filenames <- lapply(suff, paste, ...) ? Can I have lapply() reorder the arguments to FUN?

...rite a pass for LTO, and now I want to debug it using gdb. I use ld as my target file, but when I run the program in gdb, it reports [Thread debugging using libthread_db enabled] Cannot find new threads: generic error at Plugin::load() { #ifdef ENABLE_PLUGINS this->handle_ = dlopen(this->filename_.c_str(), RTLD_NOW); in binutil/src/gold/plugin.cc The gdb version is 7.0.1. I tried it with other multi-threaded programs without any problem. Have I missed something? Or I shouldn't debug my pass this way at all? btw, "llvm-gcc -use-gold-plugin" works fine when I compile my progra...

Hi, I've just tried to install winex under a mdk 8.1 linux distrib. All seems to be right untill i launch wineinstall: After answering yes,yes,/c I obtain this message : Configuring Wine for a no-windows install in /c... Created /root/.wine/config using default Wine configuration. You probably want to review the file, though. Compiling regapi... rm -f regapi && ln -s ../../wine

A lot of code runs 'qemu-img create' or 'truncate' to create blank disk images. In the past I resisted adding an API to do this, since it essentially duplicates what you can already do using other tools (ie. qemu-img). However this does simplify calling code quite a lot since qemu-img is somewhat error-prone to use (eg: don't try to create a disk called "foo:bar")
