error in process filter: Stack overflow in regexp matcher

error in process filter: Stack overflow in regexp matcher

[nenadmitrovic04]

I am trying to execute this piece of code:
 (rest (file-seq (file (str "corpus/" "ham"))).
When I execute I get this error: "error in process filter: Stack overflow in regexp matcher".
I have 1400 files in corpus/ham folder. But when I execute only three file it works.

To be able to help, people here would need at least

 - a clue on what `file-seq' does (it doesn't seem to be in
   the "standard" set of functions
 - an idea about the regular expression you are applying

As a very uneducated guess: file-seq concatenates the content of those
1400 files, and the regexp is anchored in some way that it can't let
go partial matches anchored at the beginning of this huge text. Or
something similar.

Perhaps you'll have to break up the problem into smaller pieces, but it's
difficult to say without having an idea of what "the problem" is.

I can't find any `file-seq` in Emacs's source code.  So you seem to be
using some external library.  Would be useful to give that kind
of information.

I think this was a cross post from the clojure mailing list [1].  Looks
like the issue was eventually resolved.

It looks like the poster also posted to stackoverflow[1].  He appears to 
be running clojure inside emacs.  One of the responders there suggested 
this[2] might be related to the problem.  Maybe a regexp in the mode 
used is overflowing?

At first the `str' -- not being `concat' -- led me to beleive that your sexp might be autolisp or visual lisp.
Further research leads me to believe it may be clojure.
If so, you can place your code in an org-mode file and wrap

#+begin_src clojure
(rest 
 (file-seq 
  (file 
   (str "corpus/" "ham")
)))
#+end_src

There is at least one clojure REPL available for use in emacs as well.

Best of luck in your debugging attempts.
