@ -81,10 +81,45 @@ The directory of the Vim executable is appended to $PATH. This is mostly to
make "!xxd" work, as it is in the Tools menu. And it also means that when
executable() returns 1 the executable can actually be executed.
Quotes in file names *win32-quotes*
Command line arguments *win32-cmdargs*
Quotes inside a file name (or any other command line argument) can be escaped
with a backslash. E.g. >
Analysis of a command line into parameters is not standardised in MS Windows.
Vim and gvim used to use different logic to parse it (before 7.4.432), and the
logic was also depended on what it was compiled with. Now Vim and gvim both
use the CommandLineToArgvW() Win32 API, so they behave in the same way.
The basic rules are: *win32-backslashes*
a) A parameter is a sequence of graphic characters.
b) Parameters are separated by white space.
c) A parameter can be enclosed in double quotes to include white space.
d) A sequence of zero or more backslashes (\) and a double quote (")
is special. The effective number of backslashes is halved, rounded
down. An even number of backslashes reverses the acceptability of
spaces and tabs, an odd number of backslashes produces a literal
double quote.
So:
" is a special double quote
\" is a literal double quote
\\" is a literal backslash and a special double quote
\\\" is a literal backslash and a literal double quote
\\\\" is 2 literal backslashes and a special double quote
\\\\\" is 2 literal backslashes and a literal double quote
etc.
Example: >
vim "C:\My Music\freude" +"set ignorecase" +/"\"foo\\" +\"bar\\\"
opens "C:\My Music\freude" and executes the line mode commands: >
set ignorecase; /"foo\ and /bar\"
These rules are also described in the reference of the CommandLineToArgvW API:

*win32-quotes*
There are additional rules for quotes (which are not well documented).
As described above, quotes inside a file name (or any other command line
argument) can be escaped with a backslash. E.g. >
vim -c "echo 'foo\"bar'"
Alternatively use three quotes to get one: >
