I'm not sure I understand you. By default, resource: is setup as an
alias the the directory containing the image file. But you can
override it:
factor -resource-path=/bla/bla -i=factor.image
Essentially, resource: is just a convenient alias and you are free
to put your vocab roots anywhere on the filesystem. For example, you
could add . first on the vocab roots and then you'd have a vocab
lookup similar to how Python looks up modules.
It's about the existing vocabularies. They seem to disappear when I use
an image file located elsewhere. Without vocabularies the listener
crashes too. So I wrote a script scratchVocabulary.factor:
-
USING:
io io.backend io.pathnames prettyprint
;
resource: prepend-path normalize-path . flush
vocab: prepend-path normalize-path . flush
-
With this script I can see that vocab: is affected by the location of
the image file:
-
$ cp /home/pub/factor/factor.image .
$ factor-lang scratchVocabulary.factor
/home/pub/factor/
/home/pub/factor/core
$ factor-lang -i=factor.image scratchVocabulary.factor
/home/factor/scratchVocabulary/
/home/factor
-
The reason seems to be the value of vocab-roots:
V{
resource:core
resource:basis
resource:extra
resource:work
}
So that seems to be intended and I have to live with it.
Now I also tried overriding as you suggested. No effect:
-
$ factor-lang -resource=/home/pub/factor -i=factor.image \
scratchVocabulary.factor
/home/factor/scratchVocabulary/
/home/factor
-
In addition I could not find any documentation about the command line
switch -resource.

Re: [Factor-talk] Does the location of the image file matter ?
It's because the switch is -resource-path not just -resource.

Yes, it does matter.

If a pathname begins with resource:, it is resolved relative to the
directory containing the current image (see image-path).
If a pathname begins with vocab:, then it will be searched for in all
current vocabulary roots (see Working with code outside of the Factor

tree).

So I now know that I have to keep all image files in the same directory?

Re: [Factor-talk] Does the location of the image file matter ?
Judging by the binary name factor-lang you have the factor package installed from my ppa. But it appears that you have a fresher image coming from github. You probably can't mix the two versions like that. You can try and run: resource:db absolute-path in the listener. It should show you a directory containing the db.factor file. If it doesn't something is wrong. Also swap the order of the command line arguments, it should be: -i=/home/pub/factor/project.image -run=project. 2015-07-26 12:35 GMT+02:00 Georg Simon georg.si...@auge.de: Factor 0.98 x86.64 (1565, heads/master-0-g592764d, Wed Dec 24 04:52:05 2014) [GCC 4.8.2] on linux .factor-rc USE: vocabs.loader /home/factor/ add-vocab-root I want to use snapshots without touching factor.image.
