Hello,
I have just placed on Worg [1] a short tutorial/example for using
ledger with babel. Please have a look and comment etc!
Thanks,
eric
[1] Hopefully at
http://orgmode.org/worg/org-contrib/babel/examples/ledger.php
when the php file is eventually created by the automated system.

It doesn't fit in naturally with how I would like to do things as I have many different blocks of ledger entries spread around the file... In any case, I will try to see why this doesn't work as I have used the :noweb approach for other babel codes successfully and cannot see any reason why ledger would be different.

I don't understand your argument: why wouldn't you use <<journal-home>> blocks and <<journal-work>> blocks for example, or even much more? What am I missing? What cannot be done with the noweb syntax in your Org file? I find it much better if we can avoid specifying explicit paths, in order to guarantee use and execution of our Org files by other users, on other (even Windows) machines, among others. > In any case, I will try to see why this doesn't work as I have used > the :noweb approach for other babel codes successfully and cannot see any > reason why ledger would be different. Added to my todo list... :-) Thanks... >> Though this should work as far as I understand, it does not yet... Dan very kindly spotted the following in my example: > #+src_name ledger-journal ^ It looks like a random underscore crept in there. Thanks... True that it's a bit confusing to write src sometimes with underscores (as in begin_src), sometimes not. But that's just a question of habit... Still newbie as well... Though, the following does not work yet: --8<---------------cut here---------------start------------->8--- * Test with Org-Babel-Ledger First evaluate this: (org-babel-do-load-languages 'org-babel-load-languages '((R . t) (emacs-lisp . t) (latex . t) (ledger . t) ;this is the important one for this tutorial (sh . t))) ** Journal data #+srcname ledger-journal #+begin_src ledger 2008/01/03 * (SCORPIOS ) SEB VAUBAM Assets:Bank:Checking:799997400530 550.00 EUR Assets:Bank:Transferred 2008/01/01 * ( ) UNKNOWN-PAYEE Assets:Bank:Checking:799997400530 21.91 EUR Expenses:Unknown #+end_src ** Balance Give me an overview... #+srcname: ledger-balance #+begin_src ledger :cmdline bal :noweb yes :session <<ledger-journal>> #+end_src --8<---------------cut here---------------end--------------->8--- failing with message "Error: Failed to locate any transactions; did you specify a valid file with -f?" in buffer "*Shell Command ...".

I find it weird to have all the parameters of =:cmdline= not enclosed between quotes. What should be the best option, here? That was a subject, long ago, on Org-Babel: to quote or not to quote... 2. When the evaluation produces no output, but had well produced output before, shouldn't Babel have to delete the previously written results in the Org buffer? If you don't understand what I mean, take the above example, replace =:cmdline reg unknown :noweb yes :session= by =:cmdline "reg unknown" :noweb yes :session= and see that the current results line is not removed. Would the result exist, but be different, it would have been updated. In this case, with a result before, but none on the second execution, first result is conserved in Org. Do you follow me, and agree on this?

I have no objection against this, as I have no definite view on what's better. Adding quotes would mean begin able to escape them in case the options need quotes, etc. etc. So, maybe it is better the way it currently is. The fact simply is sometimes we must add quotes, sometimes not, and that's not always intuitive (to me). Not only considering Org-Babel, but Org as a whole. See this example of `columnview': --8<---------------cut here---------------start------------->8--- #+BEGIN: columnview :hlines 1 :id "label" #+END: --8<---------------cut here---------------end--------------->8--- or of `org-collector': --8<---------------cut here---------------start------------->8--- #+BEGIN: propview :id "december" :conds ((string= spendtype "food")) :cols (ITEM amount) #+END: --8<---------------cut here---------------end--------------->8--- >>>> 2.

I've just git pulled, and tested your change. From my point of view, it does not work yet. Take this example: --8<---------------cut here---------------start------------->8--- * Journal data #+srcname: ledger-journal #+begin_src ledger 2008/01/03 * (SCORPIOS ) SEB VAUBAN Assets:Bank:Checking:799997400530 550.00 EUR Assets:Bank:Transferred 2008/01/01 * ( ) UNKNOWN-PAYEE Assets:Bank:Checking:799997400530 21.91 EUR Expenses:Unknown #+end_src * Registry Give me the details... #+srcname: ledger-registry #+begin_src ledger :cmdline reg unknown :noweb yes :session <<ledger-journal>> #+end_src #+results: ledger-registry : -21.91 EUR Expenses:Unknown --8<---------------cut here---------------end--------------->8--- With `:cmdline reg unknown', it produced the line with -21.91 EUR.

What do you mean by ledger throwing an exception? Having a return code different from 0? For me, the result block should be removed in both cases: - "exception" of ledger - empty result of ledger Or, if not, then (even better): instead of simply removing the result block, replace it with a sort of error message, saying that ledger's execution failed and returned XXX as exit code. Whatever the solution, we have to clearly be aware that the previous results are now wrong, and that the new result is a failure or empty. >> Other peculiarity, if I write `:cmdline reeg unknown', I get an >> exception: > > Ah, thanks for pointing this out, it seems I introduced an error with my > previous change.

Also, returning the error results could cause problems in the case of chained code blocks. I don't have a local ledger install, and I didn't implement the Babel ledger support, but I've made some changes to ob-ledger so that it now uses the general Babel external evaluation tools (which should raise errors as I've mentioned above).

Stupid from me... I have absolutely no idea why, but, instead of pressing C-c C-v C-e, I reused the old binging C-c C-c, hence not much happened -- as it is disabled in my `.emacs' file: (setq org-babel-no-eval-on-ctrl-c-ctrl-c t) Maybe it'd be good to echo that "no eval" occurs anymore in such a condition? Anyway, not always productive to work late... Side question, as I searched everywhere for the cause of my problem: is it totally equivalent to use `org-babel-do-load-languages' than to load individual languages? I currently have this in my config file: --8<---------------cut here---------------start------------->8--- ;; customize the `org-babel-load-languages' variable to enable support ;; for languages which can be evaluated in Org mode buffers (when (fboundp 'org-babel-do-load-languages) (org-babel-do-load-languages 'org-babel-load-languages '((R . t) (ditaa . t) (dot . t) (emacs-lisp . t) (gnuplot . t) (haskell . nil) (latex . t) (ledger . t) (ocaml . nil) (octave . t) (org . t) ;; VIP!

Or is my suggestion a bit silly? Hi Seb, in the absence of having distinct variables for this, you could make your own version, e.g. (defun my/org-babel-expand-src-block () (interactive) (let ((org-src-window-setup 'reorganize-frame)) (org-babel-expand-src-block))) Dan > > >>>> Maybe it'd be good to echo that "no eval" occurs anymore in such a >>>> condition? >>> >>> hmm, but then it would inhibit C-c C-c from performing the next action >>> in the `org-ctrl-c-ctrl-c-hook'. >> >> I mean: if C-c C-c is disabled, but run on code, then echo "I do nothing".

What am I missing? You are not missing anything at all! I didn't say it couldn't be done; I just said that it didn't fit in with *my* workflow. I have many (tens) of little to medium sized ledger snippets throughout my personal finances org file. As well as collections of entries (for regular payments, say), the set of snippets includes one-off expenses (e.g. bought a specific piece of furniture for the house) that I want to record and annotate. Labelling all of these snippets and then putting in the <<...>> entry in the full list gives two extra steps. Instead, I create as many snippets as I want without worrying about it and I simply have to /tangle/ before evaluating any of the financial summary ledger snippets. This minimises, for me, the number of things I need to remember to keep track of my finances. The other extreme is to simply put *all* ledger entries in one source block but then you might as well use a ledger file directly... Your suggestion fits bang in the middle and: > What cannot be done with the noweb syntax in your Org file? I find it much > better if we can avoid specifying explicit paths, in order to guarantee use > and execution of our Org files by other users, on other (even Windows) > machines, among others. I agree completely with this. The tutorial probably did not reflect what is likely to be the most common and more robust usage. Sorry!
