tests/run-tests: avoid C:/ in arguments MSYS replaces C:/... in arguments with C;... as it interprets the C:/ as a colon separated POSIX path list. The colon is replaced with ; (path separator on Windows) according to http://www.mingw.org/wiki/Posix_path_conversion So we must not replace \ with / for neither $TESTTMP nor $TESTDIR, but we have to keep replacing \ with / for the Popen4 call of function hghave. If we don't do the latter, test-run-tests.t will fail with $ python run-tests.py --local test-run-tests.t --- C:\Users\adi\hgrepos\hg-main\tests\test-run-tests.t +++ C:\Users\adi\hgrepos\hg-main\tests\test-run-tests.t.err @@ -70,6 +70,7 @@ tested #else $ echo skipped + skipped #endif #if false An additional tweak in test-ssh.t is needed that globs away an encoded path, as it can't be translated back to $TESTTMP, because the backslashes in the output have been already encoded as %5C. This patch makes test-ssh.t pass in MSYS on Windows.

Mercurial supports a functional language for selecting a set of
files. 

Like other file patterns, this pattern type is indicated by a prefix,
'set:'. The language supports a number of predicates which are joined
by infix operators. Parenthesis can be used for grouping.

Identifiers such as filenames or patterns must be quoted with single
or double quotes if they contain characters outside of
``[.*{}[]?/\_a-zA-Z0-9\x80-\xff]`` or if they match one of the
predefined predicates. This generally applies to file patterns other
than globs and arguments for predicates.

Special characters can be used in quoted identifiers by escaping them,
e.g., ``\n`` is interpreted as a newline. To prevent them from being
interpreted, strings can be prefixed with ``r``, e.g. ``r'...'``.

There is a single prefix operator:

``not x``
  Files not in x. Short form is ``! x``.

These are the supported infix operators:

``x and y``
  The intersection of files in x and y. Short form is ``x & y``.

``x or y``
  The union of files in x and y. There are two alternative short
  forms: ``x | y`` and ``x + y``.

``x - y``
  Files in x but not in y.

The following predicates are supported:

.. predicatesmarker

Some sample queries:

- Show status of files that appear to be binary in the working directory::

    hg status -A "set:binary()"

- Forget files that are in .hgignore but are already tracked::

    hg forget "set:hgignore() and not ignored()"

- Find text files that contain a string::

    hg locate "set:grep(magic) and not binary()"

- Find C files in a non-standard encoding::

    hg locate "set:**.c and not encoding('UTF-8')"

- Revert copies of large binary files::

    hg revert "set:copied() and binary() and size('>1M')"

- Remove files listed in foo.lst that contain the letter a or b::

    hg remove "set: 'listfile:foo.lst' and (**a* or **b*)"
