I would like to install e.g. "c:\myfunction.library" into the CoDeSys IDE, so I can add it to other projects.

I stripped one of my internal test scripts a little bit, here's the code. It demonstrates displaying all libraries, creating and deleting library repositories, and installation and uninstallation of libraries.

from __future__ import print_function
import os
for repo in librarymanager.repositories:
    print(repo.name, "(", repo.root_folder, ", ", repo.editable, ")")
    for lib in librarymanager.get_all_libraries(repo):
        print("    ", lib.displayname)
        print("        Cats: ", ", ".join(map(str, lib.categories)))
        print("        Deps: ", ", ".join(map(str, lib.dependencies)))
print("")
oldrepocount = len(librarymanager.repositories)
print("Trying to create repo")
repopath = "C:\\Path\\to\\temporary\\dir\\REPO"
os.makedirs(repopath)
    
newrepo = librarymanager.insert_repository(repopath, "Script_Test_Repo")
assert(len(librarymanager.repositories) == oldrepocount + 1)
print("Trying to install library")
libpath = "C:\\Path\\to\\Testlib.library"
installedlib = librarymanager.install_library(libpath, repo, overwrite=True)
print("Trying to find library")
foundlib, repo = librarymanager.find_library("MSch Test library, 3.4.4.0 (3S Smart Software GmbH)")
assert(repo == newrepo, "repo does not match!")
assert(foundlib == installedlib, "lib does not match!")
print("Uninstalling library")
librarymanager.uninstall_library(repo, foundlib)
print("Removing repository")
librarymanager.remove_repository(newrepo, delete_on_disk=True)
assert(not os.path.isdir(repopath), "repo deletion failed")
print("script finished.")

Here's a second script which installs all librarie swhich are found in a given directory. Our test department sometimes uses it to install all libraries which were ever released with CoDeSys into a fresh installation (for example, in a Virtual Machine).

\# -*- coding: utf-8 -*.
from __future__ import print_function
import os
\# The directory we want to install libraries from.
LIBDIRS = (r"D:\WorkingCopies\LibrariesV3Tags",)
\# Search order (compiled vs. source libraries)
EXTENSIONS = (".compiled-library", ".library")
\# disabling prompts for storage version upgrade
system.prompt_answers["UnserializableDataError2"] = PromptResult.Cancel
system.prompt_answers["LossOfDataWarning2"] = PromptResult.No
print("searching libraries to install")
repo = librarymanager.repositories[0]
for libdir in LIBDIRS:
    for extension in EXTENSIONS:
        for dir, subdirs, files in os.walk(libdir):
            for filename in files:
                if filename.endswith(extension):
                    fullpath = os.path.join(dir, filename)
                    print("installing: ", fullpath)
                    try:
                        librarymanager.install_library(fullpath, repo, overwrite=True)
                    except Exception as e:
                        print("exception: ", e)
                
print("script finished.")

Warning: I cleaned both scripts by removing some internals, and did not re-test them in their new shape, but they should still be useful for you to get the idea.

I hope that helps you a little...

Hi,

I have upgraded to V3.5 Patch 3 now and I can see that more objects has become available.

Could you provide an example using the ILibManager to install a library?

I would like to install e.g. "c:\myfunction.library" into the CoDeSys IDE, so I can add it to other projects.

Regards,
Frank

Ok. That sounds like a reasonable workaround. Thank you.

Hi,

Currently, this functionality is not available.

But there is a workaround: Pack the library into a project archive, and open that archive using open_archive. This should install all libraries contained in the archive.

This workaround should solve some of the use cases.

Regards,
Markus

Hi,

Is there a way to install new libraries in CoDeSys V3 from the script engine?

The documentation states that it is possible to add_library to a project, but I cannot find a command to install the libraries so they can be added afterwards.

I am using CoDeSys V3.4 SP3 Patch 1.

Best regards,
Frank Jepsen
