For a small project, I have the following workflow:
compile code and generate ./data and ./images
run code, which will write many files to ./data
generate images from the data files, place them in ./images
generate a video from the images
I have written a makefile, which can run the code, and compile it before, if necessary. But I don't know how to implement the dependencies of steps 3 and 4, and currently make that targets manually.
So, is there a way to check if e.g. the newest file in ./data is newer than the newest file in ./images ? It's not necessary to do this on a file-by-file basis, and the total number of data / image files is not known.
Typically the date of the directory is the date that the last file was added/modified, so you could use the timestamp on the directory itself for dependencies.
images : data
// generate images
Alternatively, if there is a mapping between the files in the two directories, you could do something like:
images/%.img: data/%.dat
// generate image...
which would prevent reprocessing data that's already been handled.

a client have a download area where users can download or browse single files. Files are divided in folder, so there are documents, catalogues, newsletter and so on, and their extension can vary: they can be .pdf, .ai or simple .jpeg. He asked me if I can provide a link to download every item in a specific folder as a big, compressed file. Problem is, I'm on a Windows server, so I'm a bit clueless if there's a way. I can edit pe pages of this area, so I can include jquery and scripts with a little freedom. Any hint?
Windows archiver is TAR and you are needing to build a TARbALL (Historically all related files in one Tape ARchive)
I have a file server which is mapped as S:\ (it does not have TAR command, and Tar cannot use URL but can use device:)
For any folders contents (including sub folders) it is easy to remotely save all current files in a zip with a single command (for multiple root locations they need a loop or a list)
It will build the Tape Archive as a windows.zip using the -a (auto) switch but you need to consider the desired level of nesting by collect all contents at the desired root location.
TAR -a[other options] file.zip [folder / files]
Points to watch out for
ensure here is not an older archive
it will comment error/warnings like the two given during run, however, should complete without fail.
Once you have the zip file you can offer post as a web asset such as
<a href="\\server\folder\all.zip" download="all.zip">Get All<a>

I am creating code coverage reports for my C++ projects using gcov/lcov, and I am trying to remove all files except the ones in a certain directory from the coverage report (i.e. I do not want different dependencies in various folders to show up in the report).
However I want to do this automatically and not manually. I tried the following:
lcov -r coverage.total '!(<path>)' -o coverage.info
But then lcov comes back with Deleted 0 files. I also tried !(<path>), '[^path]*' and slight variations of these but nothing seems to work. I can manually remove the undesired folders for example the following does work:
lcov -r coverage.total '/usr/libs/*' '/usr/mylibs/*' -o coverage.info
So my question is, how can I have lcov exclude all but a specific directory?
P.S.
I am open to workarounds (for example if this can be done with a bash script)
I am using bash+CMake+gcov+lcov
P.S.
This is not a duplicate of this question. I am asking about an automated way to only include files in a specific directory in the report. (for example the current directory) I am aware of the --remove argument but that is not an automated solution.
Your help is greately appreciated!
I am using the moderncv class to create a CV in Rmarkdown. In order to make the cv reproducible out of the box I have included the .cls and .sty files in the root directory. However, in an effort to keep the root directory uncluttered I would prefer to keep all the moderncv related files in a subdirectory (assets/tex/). I am able to access the .cls file using a relative path in the yaml front matter, but I am not able to access the .sty files unless they are in the root directory.
Searching previous questions on stackoverflow I learned the following: (1) keeping .cls and .sty files in nested directories is not recommended. I understand this and would like to do it anyway so that other people can fork my project and be able to knit the cv without having to deal with finding their texmk folder. (2) the solution to my problem seems to involve setting the TEXINPUTS using a Makefile (see this thread and another thread)
I am not very good with Makefiles, but I have managed to get one working that will knit my .Rmd file to pdf without problems, so long as the .sty files are still in root. This is what it looks like currently:
PDF_FILE=my_cv.pdf
all : $(PDF_FILE)
echo All files are now up to date
clean :
rm -f $(PDF_FILE)
%.pdf : %.Rmd
Rscript -e 'rmarkdown::render("$<")'
My understanding is that I can set the TEXINPUTS using:
export TEXINPUTS=".:./assets/tex:"
Where "assets/tex" represents the subdirectory where the .sty files are located. I do not know how to incorporate the above code into my makefile so that the .sty files are recognized in the subdirectories and my .Rmd is knit to PDF. In its current state, I get the following error if I remove the .sty files from root and put then in the aforementioned subdirectory:
! LaTeX Error: Command \fax already defined.
Or name \end... illegal, see p.192 of the manual.
which I assume is occurring because the moderncv class needs---and cannot locate---the relevant .sty files.
You could try to define the environment variable in the make rule:
%.pdf : %.Rmd
export TEXINPUTS=".:./assets/tex:"
Rscript -e 'rmarkdown::render("$<")'
Or you could set the environment variable in a set-up chunk in your Rmd file:
```{r setup, include = FALSE}
Sys.setenv(TEXINPUTS=".:./assets/tex:")
```
Note: Not tested due to lack of minimal example.
I 7Zip'd a multi-gig folder which contained many folders each with many files using the split to volumes (9Meg) option. 7Zip created files of type .zip.001,
.zip.002, etc. When I extract .001 it appears to work correctly but I get an 'unexpected end of data' error. 7Zip does not automatically go to .002. When I extract .002, it also gives the same error and it does not continue the original folder/file structure. Instead it extracts a zip file in the same folder as the previously extracted files. How do I properly extract split files to obtain the original folder/file structure? Thank you.
I've just spent few hours struggling to do a very simple task: enumerate zip file contents using C# and System.IO.Compression.
When I have zip files with small files inside, all is good.
When i use a zip file of 1.2gb which has a database file inside 4.8Gb in size i get "Number of entries expected in End Of Central Directory does not correspond to number of entries in Central Directory." I've read and I've read a lot and i cant seem to find a way to work with my archive.
The code is:
string zipPath = #"E:\Path\Filename.zip";
using (ZipArchive archive = ZipFile.OpenRead(zipPath))
{
foreach (ZipArchiveEntry entry in archive.Entries)
{
Console.WriteLine(entry.FullName);
}
}
Is there a way, any way, to use System.IO.Compression with large zip file contents? All I want is to enumerate the contents of the archive and I do not want to use any 3rd party bits as I was it was suggested on other places.
