Subject: [PATCH 8/8] stash push: support the --pathspec-from-file option
Date: Thu, 16 Jan 2020 16:09:25 +0000
Message-ID: <721410233bbee49fa13773ae9c04b4c6ed076a1a.1579190965.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.530.git.1579190965.gitgitgadget@gmail.com>

From: Alexandr Miloslavskiy <alexandr.miloslavskiy@syntevo.com>

Decisions taken for simplicity:
1) For now, `--pathspec-from-file` is declared incompatible with
   `--patch`, even when <file> is not `-`. Such use case is not
   really expected.
2) It is not allowed to pass pathspec in both args and file.

 The `--patch` option implies `--keep-index`.  You can use 
 `--no-keep-index` to override this.
 
+--pathspec-from-file=<file>::
+	Pathspec is passed in `<file>` instead of commandline args. If
+	`<file>` is exactly `-` then standard input is used. Pathspec
+	elements are separated by LF or CR/LF. Pathspec elements can be
+	quoted as explained for the configuration variable `core.quotePath`

+	literally (including newlines and quotes).
