Emacs Windows Cygwin - Error in path expansion - Cannot read journal file

[DriXse]

Hi,

Unfortunately i must use Microsoft Windows at work without administrator right.

I use emacs ,for everything, with cygwin and ledger i found only here, and all works fine without ledger-mode and org-babel. When i want to have report with block like this

#+BEGIN_SRC ledger :cmdline bal :noweb yes

ledger expand the variable %(ledger-file) incorrectly

ledger -f d\:/cygwin64/tmp/babel-6244Sli/ledger-6244ShV bal

Error: Cannot read journal file "/cygdrive/d/ledger/d:/cygwin64/tmp/babel-6244Sli/ledger-6244ShV"

Apparently, its not a "emacs ledger-mode" problem, but a problem with ledger boost library like report here https://github.com/AlexanderAA/ledger_binaries_windows/issues/3 Do you know a solution ? A way to make ledger works with Cygwin ?

Thanks a lot !

Under that issue, @ngleb has provided a gist that works for me. Try it, then put it in your $PATH, or use (setq ledger-binary-path "path/to/ledger.exe")

I have found a way to use ledger with Emacs Ledger mode on windows 10 without the "cygdrive" issue

I have noticed when you try to use ledger with the command line, cd C:\path\to\ledger\file this doesn't work : ledger -f C:\path\to\ledger\file\test.ledger bal I get : Error: Cannot read journal file "/cygdrive/c/Users/denis/Desktop/ledger/C:\Users\denis\Desktop\ledger\test.ledger"

but this is right : ledger -f test.ledger bal

So to make it work, we have to send to ledger a file name without a path. I have found "ledger-master-file" in ledger-report.el

(defun ledger-master-file ()
  "Return the master file for a ledger file.

   The master file is either the file for the current ledger buffer or the
   file specified by the buffer-local variable `ledger-master-file'.  Typically
   this variable would be set in a file local variable comment block at the
   end of a ledger file which is included in some other file."
  (if ledger-master-file
      (expand-file-name ledger-master-file)
    (buffer-file-name)))

if the variable "ledger-master-file" is not set, buffer-file-name is sent to ledger, and it has at path ...

so I've changed to :

 (defun ledger-master-file ()
  "Return the master file for a ledger file.

   The master file is either the file for the current ledger buffer or the
   file specified by the buffer-local variable `ledger-master-file'.  Typically
   this variable would be set in a file local variable comment block at the
   end of a ledger file which is included in some other file."
  (if ledger-master-file
      (expand-file-name ledger-master-file)
    (file-name-nondirectory (buffer-file-name))))

with file-name-nondirectory to get rid of the path in the file name .... And it works !

I have to take this defun into account just before using ledger, it doesn't work if I set it in my .emacs

I think this is an issue with your installation. This will break on *nix based systems.

@enderw88 yes but Ledger with Emacs on Windows is the subject of this issue ...

[enderw88]

I should have been clearer. This is not a bug in ledger-mode.

[denysos]

of course it's just a workaround for windows users ... just to wait until a fix for this issue.

@enderw88 OK, then shall we consider this issue closed?
