If you suffer from many builds requesting the same vendor libraries than cadir can help! It works e.g. with composer or npm and all other package manager that have a file to identiy the current vendor package versions (like composer.lock or package-lock.json). cadir will also run the command for installing vendors.
Checkout repository
git clone https://github.com/dirkwinkhaus/cadir.git
Build
cd cadir
mkdir build
cd build
cmake ..
make -j
Move or link the executable to somewhere the system finds it.
Lets say you have a build server. On this each branch is built many times and the vendors will change not often. Here an example for a project with npm. To see which vendors in which version are needed the identity file is "package-lock.json". On your build server you create the directory "vendorCache" in "/tmp". So here is the example:
cadir --cache-source="vendor" --identity-file="composer.lock" --cache-destination="/tmp/vendorCache" --command-working-directory=`pwd` --setup="composer install --ignore-platform-reqs --no-cache --no-interaction" --finalize="composer dump-autoload --no-interaction" --verbose
cadir will check if a directory in the cache folder exists which has a name equal to the checksum of "package-lock.json". If not, it will the command in the working dorectory for the command which installs the npm dependencies and copy it to the cache folder. If cadir finds a cached copy with a fitting name than it will copy or link it to the projekt folder.
--cache-source The directory which should be cached"
--identity-file File which shows differences
--cache-destination The directory where the cache is stored
--command-working-directory Working directory where the setup command is called from
--setup Argument which is called if cache is not found
--finalize (optional) Command which is called after cache is regenerated, linked or copied");
-v,--verbose (optional) Show verbose output
-a,--archive (optional) In case of copying the data a tar compressed archive (tar.gz) will be created
-l,--link (optional) Link cache instead of copy
-h,--help (optional) Show help
0 = Successfully executed
1 = Wrong usage of arguments
2 = Identity file error (not found/no rights)
3 = Setup command failed
4 = Finalize command failed
5 = Cannot copy to cache directoy
6 = Cannot copy from cache directoy
7 = Cannot create link from cache
8 = Removing existing cache folder failed
9 = Cannot create cache directories
10 = gzip error (only with option a, archive)
add: cache could be compressed to "tar.gz"
add: update time of cache at reading
add: whole implementation
