Re: How to read a txt file?
slurp works well, however, it reads the file in as a single string. The result may not be readily useable depending on what you are doing. I read in text files using clojure.java.io functions plus the core function line-seq. What you get is a sequence whose elements are the individual lines of the file. Then you can apply the power of the Clojure sequence library functions to the problem you are trying to solve. This gets the text file directly to a data structure which is easily processed. Here's a quick example function: (use 'clojure.java.io) (defn grab-file [file-path] (with-open [text-file-reader (reader file-path)] (do-all (line-seq text-file-reader This returns a sequence of strings. The file-path parameter is a string which is the path to the file. Other functions in clojure.java.io are very useful for dealing with files. Note the reader function is wrapped in a with-open function to make sure it is properly closed.

Re: How to read a txt file?
Roger, tryclj.com is limited in what it can do. The Clojure code you type in there is running on the web server across the network from you, not on your own local machine. That file isn't accessible there. Also for that reason many symbols are not allowed to be used in tryclj.com expressions, slurp apparently being one of them. Click on the about link on tryclj.com and read the disclaimer. If you have some version of Java installed on your local machine, or can install it, I'd recommend trying to install Leiningen to try out Clojure on your own machine, e.g. by following the "Getting Started" instructions on clojure-doc.org here: http://clojure-doc.org/articles/tutorials/getting_started.html Andy On Feb 1, 2013, at 6:12 AM, Roger75 wrote: > Hi, > > I'm trying to use this console: > http://tryclj.com/ > > the command I wrote: > (slurp "C:\\Users\\User1\\teste\\teste.txt") > > > I get this: > java.lang.RuntimeException: Unable to resolve symbol: in this context > > On Friday, February 1, 2013 10:17:43 AM UTC-2, Roger75 wrote: > I'd like to read a txt file using clojure.

Hi, I'm trying to use this console: http://tryclj.com/ the command I wrote: (slurp "C:\\Users\\User1\\teste\\teste.txt") I get this: java.lang.RuntimeException: Unable to resolve symbol: in this context On Friday, February 1, 2013 10:17:43 AM UTC-2, Roger75 wrote: > > I'd like to read a txt file using clojure.
