So how can I get at libferris from legacy apps?

Frequently Asked Questions
There are two main styles. Either using a LD_PRELOAD hack to override libc functions and switch between the original function and using libferris in the new trampoline function or by exposing libferris as an NFS or CODA server and having the kernel mount it. There are already a great deal of projects around that allow one to expose a user address space virtual filesystem to legacy applications should you require this. See this part of my links for starters.

What about "legacy" applications?

LessTif Frequently Asked Questions
Old LessTif programs may still be linked against Xm.dll while all recent ones should be linked against the libraries following the new naming scheme, i.e. Xm_12.dll, Mrm_20.dll, etc. For this legacy stuff there was a "final" version of the Motif 1.2 compatible Xm.dll being made available as of LessTif version 0.91.8 (August 2000). This is obviously quite outdated nowadays. If you really need a more up-to-date library Xm.

Is there anything like XLink in libferris?

Frequently Asked Questions
You can use emblems and their partial ordering to obtain n-ary linking in libferris. This works by considering how one would have XLink like stuff in RDF and then thinking of emblem association as triples: File has-emblem emblemName. The linking only really works effectively when you add the files that are linked into the attribute index so that you can resolve links quickly.

What is a legacy?

The Legacy Center - Preserving Stories, Values, and, Meaning
Broadly defined, a legacy is what you leave behind after you are gone. People often think of legacies in financial terms, e.g., when you bequeath your assets in a will. Today, in light of recent events in the US and the world, people are turning more attention to the idea of their spiritual/personal legacy that goes beyond material things, e.g., their stories, values, hopes, love, wishes, advice, blessings.

Is there a FUSE (fuse.sf.net) module for mounting libferris through the kernel?

Frequently Asked Questions
of libferris 1.1.93 there is a ferrisfuse 0.0.1 module which allows you to export your libferris filesystem to fuse. The three major things that you should think of feeding to the ferrisfuse module are: the libferris URL to expose, the mountpoint to access this filesystem through the kernel with and a regex of what to force to be seen as a file. The regex is there because libferris doesn't force a distinction between a file and a directory unless it really needs to.

Are any interesting bits of libferris available to my XSLT pages?

Frequently Asked Questions
Many interesting functions from libferris are exposed to XSL pages. Take a look into libferris-releasenum/xsltfunctions/ to see what is exposed, if you require any other libferris functions and you wrap them in a sensible way then patches are likely to be accepted into the mainline. The fnews RSS aggregator uses libferris functions from XSL pages so if your looking at doing that sort of thing you might wish to see how fnews does it currently.

What legacy languages can you reverse-engineer?

Engineer FAQ
Other languages are under development -- if you don't see yours, call!. We also have tools that let us work with the HTML produced by almost any application that runs in a browser window.

What do you do with the business logic in a legacy application?

Engineer FAQ
Business logic means different things to different people. For example, we routinely create new code to validate fields, manage foreign key lookups, handle required fields, and more -- all without having to use legacy logic in any direct sense. But let's talk about the kind of substantial business logic that might compute a stock quantity or implement a business policy. Our approach to that kind of legacy business logic varies by project and language.

What is the Legacy Virus? Who's had it? Hasn't there been a cure for a while?

rec.arts.comics.marvel.xbooks Frequently Asked Questions Par...
The Legacy Virus was a once-interesting plot device that served as a parallel to the AIDS/HIV virus. Basically, it was spread from mutant to mutant, and it caused mutants to die by accelerating or increasing their powers to the point that they burned themselves out. Obviously, such a nasty virus caused even more fear of mutants in the Marvel Universe. with all plot devices, it started out interesting and became a cliche.

How do I develop C# apps?

Andy Mc's C# FAQ for C++ programmers
The (free) .NET SDK contains the C# command-line compiler (csc.exe). Visual Studio has fully integrated support for C# development. On Linux you can use Mono. Use C++ with .NET. Microsoft supply a .NET C++ compiler that produces IL rather than machine code. However to make full use of the .NET environment (e.g. garbage collection), a set of extensions are required to standard C++. In .NET 1.x this extended language is called Managed Extensions for C++. In .NET 2.

I installed LessTif but I can't compile apps with it. What's wrong ?

LessTif Frequently Asked Questions
You may have an application that's not error-free; or (more likely) one which needs configuration for your site, computer platform, etc. If it's not a bug within the application it probably has to do with your compiler options. If it's indeed that, there are several possibilities. In the examples we'll give now, we'll be using some installation directories that may differ from your installation.

Why don't statically linked apps work?

LessTif Frequently Asked Questions
You need to call _LtXmFixupVendorShell() at the beginning of main(), or at least before accessing the LessTif library somehow. Note that this call was not always exported from earlier versions of the Xm*.dlls. It does and will always exist from version 0.92.26 and above. For further technical details check out the source code in lib/Xm/Vendor.c and read the answer to "Application fails to start".

Information about what emblems are attached to a file, changes made to the contents of various filesystems such as db4. Using this a GUI client can just watch a path within a db4 file and see the changes that a command line tool makes to the contents of that db4 file. This was originally added so that filesystems like apps:// can be links to db4 files in ~/.ferris but clients are not effected by this choice, ie.

I don't see my legacy language in your list. Can you help me anyway?

Engineer FAQ
Usually, yes. Since our tools are designed to adapt to new languages, it is usually a matter of a few weeks to support a new language. We like doing that! Even if your legacy application is very small, we can just write SDL for it by hand and rapidly develop a modern version.
