Module For COM Objects
Does Clojure have a module that allows initializing, passing data to, and finalizing COM objects? I am asking, because I need to write a Clojure program to communicate with a COM toolkit.

Natively Compiled Clojure
I use Clojure primarily as a very reliable tool to aid in data transformations, that is taking data in one application's database and transforming it into the format needed for another applications' database. So, my question is would a natively compiled Clojure make sense or turn the language into something that was not intended? In almost all instances I have not found a problem with Clojure's execution speed so my question is not about pro or anti Java.

Is There An Upcoming Book On Clojure Macros?
I have most of the Clojure text books available, and have found them all to be quite good. Each one seems to have a different focus, which, depending on the problem at the time, shines light on my particular problem du jour. IMHO, while the current crop of books is quite good, none that I've seen so far talk about Clojure's macros in heavy detail, like for more than a chapter. I am reading Doug Hoyte's Let Over Lambda, and am wondering if there is a more macro-focused book in the works for Clojure. I like Let Over Lambda, because it is the first book I've seen so far that blends in topics of how variables are represented on the stack along with presenting Lisp macros.

Re: If Using nth Creates Dependencies, What Is The Best Way To Pull Data Elements From A Sequence

If Using nth Creates Dependencies, What Is The Best Way To Pull Data Elements From A Sequence
In our production development environment, we perform a lot of data transfers between diverse systems, and most of those transfers involve comma-delimited (.csv) data. So my first small Clojure applications have revolved around the clojure-csv library. While learning Clojure I have seen the comment that using nth "stinks", because it creates dependencies. Wanting to do things in a Clojure way, I have a question. If I need to extract a number of columns of a spreadsheet to minimize the dataset and this happens as the application is reading in and initializing its data, what should I use to extract those columns other than nth? And, if I use a series first and rest, isn't that also positional? I've thought of ways to re-position the data initially, so comparison columns between two different spreadsheets that have one unique key column in common would be accessible with first, for example. However, I would still need to get at that data by column in order to reposition it, hence the need for nth. -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: How to convert general recursion to loop .. recur syntax
Alan: I may have misunderstood what I've read both in books, blogs, and the Clojure site, but it seems that writing recursive functions in the loop .. recur style is the preferred style. I also remember most of the texts currently out on Clojure say use the higher level sequence functions rather than recursion. I get it. I wanted to do this particular exercise without the aid of Clojure.zip. -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: How To Empty A Tree or Returning The Skelton of A Tree Without Leaves
This isn't a request to get help w/ a 4Clojure problem, and I am not specifically asking for help with producing the skeleton (the tree structure without the leaves) of the sequences show below, although I would be appreciative of help. Instead I am asking if a solution to do this is simple or requires an approach like clojure-zip. Thanks for the 4clojure group link. Didn't know it existed.

How To Empty A Tree or Returning The Skelton of A Tree Without Leaves
When I started learning Clojure, I did not want to be a casual user that shyed away from Clojure's native syntax, preferring to do as much as possible in Java. To that end, I discovered some graduate computer science Clojure exercises and started working them. I know about 4Clojure, but these exercises made my head hurt, but as the Gary Larson cartoon told it, it was a "good kind of hurt". By forgoing the use of flatten and trying to roll my own, I gained some insights of how sequences are constructed and what they actually are. However, coming across the exercise to return the skeleton of a tree, I immediately thought of meta data, but I'm not sure this exercise was designed to encourage the students to use the clojure.zip routines. So, my question is, using elementary primitives, is it reasonable to return a list without its leaves, or do you really need the clojure.zip functions?

Re: Differences Between seq? and sequential?
And in flattening a list (by hand, not using flatten), why it important to check for sequential instead of seq and where can I read about that? I understand one answer.

Documentation For Lisp Programming in Clojure.
I have seen the three current books on Clojure. They are all good general books that describe the whole language. I have not had a chance to see Chas Emerick's new Clojure O'Reilly book, so cannot comment on that. Are there any books available or upcoming that concentrate more on Lisp programming in Clojure's dialect? If not, what is the closest Lisp dialect to Clojure and is the best book on teaching traversing trees, recursion, and so on?

Re: Adding "Change History" To Clojure Modules
We have a fairly simple development environment here, not that it
couldn't stand updating, but other than a consultant, I am the only
developer. I need changes written directly into each file. and here is
why.
When I got here over seven years ago, there were well over 200 4GL
modules and a smattering of C modules built into Informix's customized
runner for 4GL pcode. Almost no module had comments; and almost no
module had module header information. We also had no formal build.
Yes, I could look things up in CVS, but I find it better to have stuff
written in the header.
I'm using $Log$, and it works.
Thanks.

Best Way To Remove vector from vector of vectors?
I get back a vector of vectors from clojure-csv/parse-csv. I want to remove vectors from that sequence based on the out come of certain tests on individual vector elements. Below, get-parsed-csv-file is called first and returns clean-csv-rows. filter-parsed-csv-rows is called with clean-csv=rows, but is not returning anything. I'm trying to figure out why. (defn gen-parsed-csv-file "Returns a sequence generated by parse-csv" [file-name] (let [ data (slurp file-name) all-csv-rows(parse-csv data) clean-csv-rows (if (= 0 (count (first (last all-csv- rows (drop-last 1 all-csv-rows) all-csv-rows)])) (defn filter-parsed-csv-rows "Returns cleaned-up parsed csv rows." [all-csv-rows] (reduce (fn [checked-row one-csv-row] (if (and (> 0 (count one-csv-row)) ((not (cstr/blank? (nth one-csv-row 5 nil) (conj checked-row one-csv-row))) [] all-csv-rows)) -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Where Are Clojure's (Cake') Build Steps Document
On a production system, I would like to implement less sophisticated build shell scripts without the benefit of having installed cake or its dependencies. I am using cake on my Ubuntu development workstation; it works well. However, when Cake fetches dependencies, all that detail is hidden. Therefore, I am wondering where Clojure's build steps are documented, including fetching dependencies.

So far, my problems have not been related to CLASSPATH, but instead revolve around understanding the differences in how different packages are built. Also, the structure of different library's build directories that I have seen on github varies quite a bit. I am building an application and only need my source in ./project_name/ src/project_name.clj, but some libraries I have seen have a project_name/project_name.clj under source. For beginners, it is a roadblock. But because of this group, the roadblock, at least for me, is temporary. > > As for complicated installation instructions, libraries meant to be used in > lein have installation instructions that generally look like this: > > [compojure "0.6.4"] > > The other alternative is to have environment package managers like Python > with easy_install and Ruby with gems.

I want to create a map of this output: PremiseID Reading 61016 101100 610159000 411200 610158000 133100 610157000 239400 nil nil produced by this function (defn process-file "Process csv file and prints a column in every row" [file-name] (let [data (slurp file-name) rows (parse-csv data)] (doseq [this-row rows] (println (nth this-row 11 nil) (nth this-row 1 nil) from this data: "MeterID","Reading","ReadingDateTime","Account","CustomerLN","CustomerFN","DeviceID","DeviceType","ChannelNumber","DecodeType","LoadDateLocal","PremiseID" 33891715,101100,"2011-06-05 23:00:00","61016","SMITH","E & J", 80581200,43,0,75,"2011-06-06 06:00:01","61016" 33891773,411200,"2011-06-05 23:00:00","610159000","COMMONER","A", 80598726,43,0,75,"2011-06-06 06:00:01","610159000" 33891887,133100,"2011-06-05 23:00:00","610158000","JONES","J & M", 80581189,43,0,75,"2011-06-06 06:00:01","610158000" 33891825,239400,"2011-06-05 23:00:00","610157000","SAWTOOTH","GEORGE C",80598731,43,0,75,"2011-06-06 06:00:01","610157000" tnx cmn On Jun 30, 4:24 pm, Ken Wesson wrote: > On Thu, Jun 30, 2011 at 4:15 PM, octopusgrabbus > > > > > > > > > > wrote: > > The dorun in this function > > > (defn process-file > > "Process csv file and prints first item in every row" > > [file-name] > > (let [data (slurp file-name) > > rows (parse-csv data)] > > (dorun (map #(println (first %)) rows > > > causes each row of vectors in rows to be processed. > > > (doseq [a-row rows] (println a-row) ) > > > would print each row in the data, which looks like this (the real > > data, not the test data I've been using today.) > > > "MeterID","Reading","ReadingDateTime","Account","CustomerLN","CustomerFN","DeviceID","DeviceType","ChannelNumber","DecodeType","LoadDateLocal","PremiseID" > > 33891715,101100,"2011-06-05 23:00:00","61016","SMITH","E & J", > > 80581200,43,0,75,"2011-06-06 06:00:01","61016" > > 33891773,411200,"2011-06-05 23:00:00","610159000","COMMONER","A", > > 80598726,43,0,75,"2011-06-06 06:00:01","610159000" > > 33891887,133100,"2011-06-05 23:00:00","610158000","JONES","J & M", > > 80581189,43,0,75,"2011-06-06 06:00:01","610158000" > > 33891825,239400,"2011-06-05 23:00:00","610157000","SAWTOOTH","GEORGE > > C",80598731,43,0,75,"2011-06-06 06:00:01","610157000" > > > It would be nice if the let statement would allow populating a local > > variable from iterating all the rows of vectors.

Re: Filling let local variable from sequence
The dorun in this function (defn process-file "Process csv file and prints first item in every row" [file-name] (let [data (slurp file-name) rows (parse-csv data)] (dorun (map #(println (first %)) rows causes each row of vectors in rows to be processed. (doseq [a-row rows] (println a-row) ) would print each row in the data, which looks like this (the real data, not the test data I've been using today.) "MeterID","Reading","ReadingDateTime","Account","CustomerLN","CustomerFN","DeviceID","DeviceType","ChannelNumber","DecodeType","LoadDateLocal","PremiseID" 33891715,101100,"2011-06-05 23:00:00","61016","SMITH","E & J", 80581200,43,0,75,"2011-06-06 06:00:01","61016" 33891773,411200,"2011-06-05 23:00:00","610159000","COMMONER","A", 80598726,43,0,75,"2011-06-06 06:00:01","610159000" 33891887,133100,"2011-06-05 23:00:00","610158000","JONES","J & M", 80581189,43,0,75,"2011-06-06 06:00:01","610158000" 33891825,239400,"2011-06-05 23:00:00","610157000","SAWTOOTH","GEORGE C",80598731,43,0,75,"2011-06-06 06:00:01","610157000" It would be nice if the let statement would allow populating a local variable from iterating all the rows of vectors.

Re: Filling let local variable from sequence
If I have rows of vectors, such as the return from clojure-csv\parse- csv ["a" 1 "b" 2 "c" 3 "d" 4] ["e" 5 "f" 6 "g" 7 "h" 8] How can I break up each row? I've tried doseq in the let statement, but get an error. On Jun 30, 2:27 pm, octopusgrabbus wrote: > Thanks.
