Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
The function split-string-and-unquote is a great help in taking apart
shell command lines, but the values it returns seem incorrect in some
situations, at least from shell command quoting perspective:
(split-string-and-unquote "foo\ bar")
=> ("foobar") [where's my blank?]
(split-string-and-unquote "foo\\\ bar")
=> ("foo\\bar") [where's my blank?]
(split-string-and-unquote "foo\" \"bar")
=> ("foo" " " "bar") [where's my blank]
(split-string-and-unquote "foo\"*\"bar")
=> ("foo" "*" "bar") [can't quote in the middle of a string?]
(split-string-and-unquote "foo\\\"bar")
=> End of file during parsing [how do you quote a quote?]
Also, it doesn't support '..' quoting, which is quite frequent in
shell commands.
If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
`bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
d:/gnu/emacs/etc/DEBUG for instructions.

It's the unquoting that didn't work for me in the cases I described in the bug report. Adding more text just so it could split doesn't change the problematic behavior, but would clutter the bug report with irrelevant details. ^ permalink raw reply [flat|nested] 24+ messages in thread

You know, since you evidently know better, how about if you explained what that pair of functions is supposed to do, exactly, and what are their intended uses? The doc strings fall short by a large margin, and NEWS had this to say about these functions: *** `split-string-and-unquote' does (what?) *** `combine-and-quote-strings' does (what?) If I can understand the explanation, maybe I could produce from it a suitable section of the ELisp manual, which is the reason why I started to play with split-string-and-unquote. Failing that, I will stick to my interpretation. Here's what I wrote in the ELisp manual about these two functions; comments and corrections, if someone has them, are greatly appreciated: @cindex quoting and unquoting shell command line The following two functions help creating shell commands from individual argument strings and taking shell command lines apart into individual arguments. @defun split-string-and-unquote string &optional separators This function splits @var{string} into substrings at matches for the regular expression @var{separators}, like @code{split-string} does (@pxref{Creating Strings}), but it additionally removes quoting from the substrings. It then makes a list of the substrings and returns it. If @var{separators} is omitted or nil, it defaults to @code{"\\s-+"}, which is a regular expression that matches one or more characters with whitespace syntax (@pxref{Syntax Class Table}). The quoting this function supports is of 2 styles: by enclosing a whole string in double quotes @code{"@dots{}"}, or by quoting individual characters with a backslash escape @samp{\}. The latter is also used in Lisp strings, so this function can handle those as well. @end defun @defun combine-and-quote-strings list-of-strings &optional separator This function concatenates @var{list-of-strings} into a single string, quoting each string in the list that needs quoting as it goes. It also sticks the @var{separator} string in between each pair of strings in the result, and returns that result. If @var{separator} is omitted or @code{nil}, it defaults to a blank @code{" "}. The strings in @var{list-of-strings} that need quoting are those that include @var{separator} as their substring. Quoting a string encloses it in double quotes @code{"@dots{}"}. In the simplest case, if you are consing a shell command from the individual command-line arguments, every argument that includes embedded blanks will be quoted. @end defun ^ permalink raw reply [flat|nested] 24+ messages in thread

AFAIK, these two functions are meant to: - provide a way to specify any list of strings within a single string (i.e. it needs to provide some separators and some way to quote the separators), using a format that's simple to type for the end user. - be inverse of each other; more precisely (equal STR (split-string-and-unquote (combine-and-quote-strings STR))) this is also stipulated in the docstring of split-string-and-unquote. As the docstring of split-string-and-unquote explains, the quoting used is the same as the one used for ELisp strings. I could have used sh-style quoting or csh-style, or any other style, but csh-style is nasty, sh-style is too powerful (what should we do with backquotes and $(...)), and ELisp is what Emacs uses already and it's reasonably simple and we know it handles all cases reasonably well, so it seemed like an OK choice.
