tree doesn't get called

stranded as usual.

So here's the package
http://paste.lisp.org/display/345871

What is wrong with it ?

The build fails, the build folder (kept in /tmp) is empty

Further, when I attempt to call tree, tree doesn't get called

Thanks in advance

trivial-build-system requires you to do a lot manually.  In this case
'(zero? (system* "tree"))' fails because it's not found in $PATH.  

And the build folder is empty because the builder doesn't put anything
there! :)  Since you're working from a git checkout here, you could
probably copy/compile things directly from the source checkout to 'out'.

Hope that helps,

Thank you so much or your help

Would you mind to take a look at this new version ?

http://paste.lisp.org/display/346142

The

(copy-file file
           dest-file)

piece fails with

...
In unknown file:
   ?: 0 [copy-file "include.scm" ...]

ERROR: In procedure copy-file:
ERROR: In procedure copy-file: No such file or directory

But as you can see on te "tree" output, include.scm is there indeed

Thanks in advance

It looks like you first need to create the target directory (with
“mkdir-p”).

BTW: instead of an explicit list for scm-files you could use this:

    (find-files "." "\\.scm$")

Please always include the relevant code snippets in the email itself,
rather than using a paste site.  Paste sites are useful for contexts
such as IRC where pasting more than a few lines is inconvenient and
generally frowned upon, and where the discussions are ephemeral.

On the other hand, these email lists are archived and we would like the
archives to be comprehensible to future readers.  That will not be
possible for the emails in this thread after the code under discussion
has been deleted from the paste site, or the paste site goes offline.

There are also privacy implications to forcing the readers of your email
to click on a link, thus creating network traffic and a log on someone's
server, in order to see the core content of your message.

What do you think?

    Regards,
      Mark

Thanks, Ricardo.

This is the new error

ice-9/eval.scm:386:9: In procedure eval:
ice-9/eval.scm:386:9: Throw to key `match-error' with args `("match" "no
matching pattern" ("" "/include" "scm"))'.


I guess the culprit is this


(for-each (lambda (file)
        (let* ((dest-file ...)
           (go-file (match (string-split file #\.)
                   ((base _)
                    (string-append module-dir "/" base ".go")))))...)))

The first file processed is "include.scm"

I'm not sure what "no matching pattern" means
The spliitting in "include" and "scm" seems corretc (where does that slash
come from ?)

And i I switch back to the explicit list of files, I get:

wrote
`/gnu/store/mdirmfqcs2cadk8ram89j7i0z9zlrqvb-guile-miniadapton-master/share/guile/site/2.2/include.go'

So the first file ("include.scm") gets correctly written

But then:

what does this error message mean ?

I'm just a bit confused

I'm ready to adhere to any guidelines set set by the community

I have no problem in pasting pieces of code directly in the emails body

I just hadn't considered the concerns you are raising

In fact, I'd paste code even on IRC channels, I don't do so because I have
been requested to abstain from pasting code in chat channels in the past

But I don't understand the reason why that is not desirable, inconvenient
and frown upon.

I just adhere to a costme that seems to be common and widely accepted, or
even assumed.

I can do te same for mailing lists of course. I just thought the set of
assumptions was the same

So I will follow your lead in the future, I have begun already !

In this same thread I reported errors and pieces of code pasting the wole
thing in the email body

It's even more practical, like this !

IRC is for real-time conversations, and pasting many lines of code there
makes it hard to converse.  A channel can be very crowded even without
pasting code snippets, so it’s best to keep excess text to a minimum.  I
guess that’s why it’s customary on IRC to paste code elsewhere and just
link to it.

For mails it’s fine (and desirable) to include code snippets inline or
as attachments.

The differences with my version is that you use install-file insted of
copy-file  and you pass the -L (cwd) switch to guild

I wonder what was causing my issue ?

I forgot: the linter crashes, but not only on guile-miniadapton. Also on
guile-irregex that was already there

It might be something in the maser branch or something in my setup. I
updated my system recently and I still don't know what is going on.

Well, I know what is going on less than usual ;-)

Thanks again !

These were mostly cosmetic changes.  I evaluate “(getcwd)” once and bind
it to “cwd” instead of evaluating it again and again for each file.
This is not what fixed the crash.

“install-file” only takes a file and a directory, unlike “copy-file”
which takes a source file name and a target file name.  I did this just
to simplify the code.

> I wonder what was causing my issue ?

Another difference is that I’m using “basename”.  Your use of “match”
didn’t work, because the match pattern wasn’t correct for the
“find-files” case.

Yes I get that, I wrote "-L (cwd)" ust for brevity ;-)

My use of match didn't work, but it hanged also when I used an explicit list

Admittedly I had probably messed up the call to basename

Oh well

Thanks anyway

I cannot reproduce this running “./pre-inst-env guix lint guile-irregex”
on master.

So it must be my setup.

Interestingly, this happens also in the other master folder that I keep

We'll see

Thanks or checking !
