Detecting path at runtime

[David Paleino]

Hello *,
still trying to use NAnt for my mono project :)
I'd need to detect the PATH of `mono' at build-time: with 0.86-beta1 I'd do:

framework::get-tool-path('mono')

But I couldn't find any similar function in <= 0.85. Is there any workaround I
could adopt?

Kindly,
David

You could just take the code from the beta and put it into a script task
in your .85 build script.

David,

Can I ask why you need the path to the mono shellscript?

Because I'm installing a wrapper for my assembly (/usr/lib/foo/foo.exe)
in /usr/bin/foo.

This is the wrapper:

$ cat gnome-rdp.in
#!/bin/sh
exec @MONO@ @libdir@/gnome-rdp/gnome-rdp.exe $MONO_EXTRA_ARGS "$@"

And, in my buildfile:

<copy file="gnome-rdp.in" tofile="${outdir}/gnome-rdp">
  <filterchain>
    <replacetokens>
      <!-- only in NAnt >=0.86-beta1 -->
      <!--token key="MONO" value="${framework::get-tool-path('mono')}" /-->
      <token key="MONO" value="/usr/bin/mono" />
    </replacetokens>
  </filterchain>
</copy>

Bob,

Nope, that's not an option. Tool-path support was introduced in .86.

It's possible to get that path using .85, but I actually doubt whether David
really needs the path.

Perhaps we offer an alternative that works "cross-framework".

Sure, thanks, but I'd regard this as a "last resort"...


Thanks for the hint,

Obviously, this is not standard. One might want [1] to use a version
in /usr/local/bin/, for example, and that line is failing for this user.

[1] e.g. by putting /usr/local/bin before /usr/bin in $PATH.

Kindly,
David

David,

You have three options:

* use pkg-config.

  <token key="MONO"
value="${pkg-config::get-variable('mono','prefix')}/bin/mono" />

* use framework::get-runtime-engine.

  For example:

  <token key="MONO"
value="${framework::get-runtime-engine(framework::get-target-framework())}"
/>

* modify your shellscript to find the path to mono (using pkg-config).

  For example:

  #!/bin/sh
  exec `pkg-config --variable=prefix mono`/bin/mono
@libdir@/gnome-rdp/gnome-rdp.exe $MONO_EXTRA_ARGS "$@"

My preference goes to the last option, as your script would continue to work
if someone decides to move mono after you app is installed.

Hope this helps,

Gert
