New variable ffap-paths-with-spaces controls if the behavior is in use. By default it is set to "t" in Windows/Cygwin where spaces in paths are encountered. 2. The "path skipping" is based on finding longest distance: - from first "drive letter", "/" or "\" - until last "/", "\" followed by last non-matching-char-not-usually-found-in-file-names 3. In Cygwin Emacs the paths are expected to be in "/cygdrive//" format. This is handled as a last step. Test by placing cursor anywhere of these path names and evaluating with "M-:" the lisp code "(ffap-string-at-point)" over them: ;; c:/Program Files/Open Text Evaluation Media/Open Text Exceed 14 x86/Program here.txt ;; c:/Program Files/Open Text Evaluation Media/Open Text Exceed 14 x86/Program Files/Hummingbird/ ;; c:\Program Files\Freescale\CW for MPC55xx and MPC56xx 2.10\PowerPC_EABI_Tools\Command_Line_Tools\CLT_Usage_Notes.txt It is not possible to test the above paths with "M-x ffap" as the code by design starts to chop path components if the path does not exist in current environment. See: (defun ffap-file-at-point () ...near the end.... ;; Try all parent directories by deleting the trailing directory ;; name until existing directory is found or name stops changing I'm sure the patch is not perfect as it's hard to come by a strategy to deal with spaces but it appears to give good results. I think users' would benefit from the space detection support.

(I don't use ffap, so take the below with a grain of salt.) Several things come to mind: . You could modify the heuristics depending on the major mode. E.g., if it's Text or anything derived from text, file names with spaces will generally be delimited by quotes. . You could by default stop "skipping" when you see common words like "on", "and", "or", "and/or", etc. . You could by default stop when the slash flavor changes, like first \, then / (see my example). . At least in text modes, punctuation (with the notable exception of a period) will not normally be part of a file name. > | > 3.

Sorry, I don't follow. You said "In Cygwin Emacs the paths are _expected_ to be", so I assumed you mean the file names on Cygwin are _required_ to be in the /cygdrive/x/foo form. Maybe I misunderstood what you meant.

c:/Program= Files/Freescale/CW for MPC55xx and MPC56xx 2.10/PowerPC_EABI_Tools/Command= _Line_Tools/CLT_EABI_PPC_Tools_Notes.txt

c:\Program Files\Open Text Evaluation Media\Open Text Exceed 14 x86\Program= Files\Hummingbird\

From a user view this is a very helpful and usef= ul solution to get to these files/dirs in one keystroke.

Thanks to J= ari for the hard work.

I will report if I find issues.

User can enable/disable if spaces are taken into account. If enabled,=
the result is:

=A0 "C:\emacs\bin\prog1.exe on Windows or /usr/bin/prog1"

If disabled, depending on cursor position:

=A0 "C:\emacs\bin\prog1.exe"
=A0 "/usr/bin/prog1"

If you have strategiy to make it better, please suggest.

Only "<drive letter>:" is converted into "/cygdr= ive/<drive letter>" under
Cygwin.

Eli, excuse me very much, but you cheating. Even under Unix (where spaces inside filenames are very unusual) people instinctively trying heavy to distinguish/decorate them from outside/descriptive text. The only one problem that there no consensus about how to do it. What characters pair to use? <>? ""? ''? But anyway just separate filename with possible spaces just by spaces... It's out of my ability to imagine. Therefore, I would to discard this example as rare. After all, any heuristic have his own false positives (and it is the reason, why I said "cheating": for every heuristic it's always possible to imagine a situation/input data when heuristic will fail). But, if there no way to make false positives amount small enough, I would to propose an idea for extension: find-file-at-region(). You just select a region of text, and Emacs tries to interprets it as default value for find-file(). > >> 3.

It was intended as a very last resort, if there will be no reasonable way to avoid 50%/50% false positive/negative ratio. Logic was very simple: in any way to mark a region and call a function is faster than to mark a region, copy, call a function, paste and, optionally if copied pathname is relative, move to the beginning of the pasted pathname and then to kill to the beginning of minibuffer. > On Windows I use these type of paths: > > c:/Program Files/Open Text Evaluation Media/Open Text Exceed 14 x86/Program Files/Hummingbird/Connectivity/14.00/Default User/PerUser Settings.ini > c:\Program Files\Open Text Evaluation Media\Open Text Exceed 14 x86\Program Files\Hummingbird\Connectivity\14.00\Default User\PerUser Settings.ini > > c:/Program Files/Open Text Evaluation Media/Open Text Exceed 14 x86/Program Files/Hummingbird/ > c:\Program Files\Open Text Evaluation Media\Open Text Exceed 14 x86\Program Files\Hummingbird\ > > With Jari solution I can get to the file/dir in one keystroke. > I think that this is the power of emacs.

I don't see the relationship with cheating. Yes, his example is probably not too important, but I think if we want to add support for spaces we first need to decide which cases we want to handle, since the general case is simply impossible. Here are some disorganized thoughts: - many of the examples shown in this thread have to do with "one file name per line". But if noone tells us beforehand that the file name goes to EOL, handling these well will unavoidably end up with too many false positives. - we should think of good hints for beginning/end of file names. E.g. I think if we find something that matches "['\">,.][ \n]", we should probably assume it's the end of the file name (EOFN). Or " /" is probably a BOFN, whereas "/ " is an EOFN. - maybe if the separators are forward slashes, we should assume that there's no space in the file name. > But, if there no way to make false positives amount small enough, I > would to propose an idea for extension: find-file-at-region().

FWIW: As the submitter of the original bug report (#6695), I'd say this shouldn't be marked "fixed" if the drive letter part (e.g. c:/) isn't included on MS Windows. It sounds like it represents some progress, but it sounds like it's not fixed yet.
