The qapplied command prints the current stack of applied patches. Patches are printed in oldest-to-newest order, so the last patch in the list is the “top” patch.

The qcommit command commits any outstanding changes in the .hg/patches repository. This command only works if the .hg/patches directory is a repository, i.e. you created the directory using hg qinit -c or ran hg init in the directory after running qinit.

This command is shorthand for hg commit --cwd .hg/patches.

The qdelete command removes the entry for a patch from the series file in the .hg/patches directory. It does not pop the patch if the patch is already applied. By default, it does not delete the patch file; use the -f option to do that.

Options:

The qdiff command prints a diff of the topmost applied patch. It is equivalent to hg diff -r-2:-1.

The hg qfinish command converts the specified applied patches into permanent changes by moving them out of MQ's control so that they will be treated as normal repository history.

The qfold command merges multiple patches into the topmost applied patch, so that the topmost applied patch makes the union of all of the changes in the patches in question.

The patches to fold must not be applied; qfold will exit with an error if any is. The order in which patches are folded is significant; hg qfold a b means “apply the current topmost patch, followed by a, followed by b”.

The comments from the folded patches are appended to the comments of the destination patch, with each block of comments separated by three asterisk (“*”) characters. Use the -e option to edit the commit message for the combined patch/changeset after the folding has completed.

Options:

The qheader command prints the header, or description, of a patch. By default, it prints the header of the topmost applied patch. Given an argument, it prints the header of the named patch.

The qimport command adds an entry for an external patch to the series file, and copies the patch into the .hg/patches directory. It adds the entry immediately after the topmost applied patch, but does not push the patch.

If the .hg/patches directory is a repository, qimport automatically does an hg add of the imported patch.

The qinit command prepares a repository to work with MQ. It creates a directory called .hg/patches.

Options:

When the .hg/patches directory is a repository, the qimport and qnew commands automatically hg add new patches.

The qnew command creates a new patch. It takes one mandatory argument, the name to use for the patch file. The newly created patch is created empty by default. It is added to the series file after the current topmost applied patch, and is immediately pushed on top of that patch.

If qnew finds modified files in the working directory, it will refuse to create a new patch unless the -f option is used (see below). This behavior allows you to qrefresh your topmost applied patch before you apply a new patch on top of it.

Options:

The qnext command prints the name name of the next patch in the series file after the topmost applied patch. This patch will become the topmost applied patch if you run qpush.

The qpop command removes applied patches from the top of the stack of applied patches. By default, it removes only one patch.

This command removes the changesets that represent the popped patches from the repository, and updates the working directory to undo the effects of the patches.

This command takes an optional argument, which it uses as the name or index of the patch to pop to. If given a name, it will pop patches until the named patch is the topmost applied patch. If given a number, qpop treats the number as an index into the entries in the series file, counting from zero (empty lines and lines containing only comments do not count). It pops patches until the patch identified by the given index is the topmost applied patch.

The qpop command does not read or write patches or the series file. It is thus safe to qpop a patch that you have removed from the series file, or a patch that you have renamed or deleted entirely. In the latter two cases, use the name of the patch as it was when you applied it.

By default, the qpop command will not pop any patches if the working directory has been modified. You can override this behavior using the -f option, which reverts all modifications in the working directory.

Options:

The qpop command removes one line from the end of the status file for each patch that it pops.

The qprev command prints the name of the patch in the series file that comes before the topmost applied patch. This will become the topmost applied patch if you run qpop.

The qpush command adds patches onto the applied stack. By default, it adds only one patch.

This command creates a new changeset to represent each applied patch, and updates the working directory to apply the effects of the patches.

The default data used when creating a changeset are as follows:

If a patch contains a Mercurial patch header, the information in the patch header overrides these defaults.

Options:

The qpush command reads, but does not modify, the series file. It appends one line to the hg status file for each patch that it pushes.

The qrefresh command updates the topmost applied patch. It modifies the patch, removes the old changeset that represented the patch, and creates a new changeset to represent the modified patch.

The qrefresh command looks for the following modifications:

Even if qrefresh detects no changes, it still recreates the changeset that represents the patch. This causes the identity of the changeset to differ from the previous changeset that identified the patch.

Options:

The qrename command renames a patch, and changes the entry for the patch in the series file.

With a single argument, qrename renames the topmost applied patch. With two arguments, it renames its first argument to its second.

The qseries command prints the entire patch series from the series file. It prints only patch names, not empty lines or comments. It prints in order from first to be applied to last.

The qtop prints the name of the topmost currently applied patch.

The qunapplied command prints the names of patches from the series file that are not yet applied. It prints them in order from the next patch that will be pushed to the last.

The hg strip command removes a revision, and all of its descendants, from the repository. It undoes the effects of the removed revisions from the repository, and updates the working directory to the first parent of the removed revision.

The hg strip command saves a backup of the removed changesets in a bundle, so that they can be reapplied if removed in error.

Options:

The series file contains a list of the names of all patches that MQ can apply. It is represented as a list of names, with one name saved per line. Leading and trailing white space in each line are ignored.

Lines may contain comments. A comment begins with the “#” character, and extends to the end of the line. Empty lines, and lines that contain only comments, are ignored.

You will often need to edit the series file by hand, hence the support for comments and empty lines noted above. For example, you can comment out a patch temporarily, and qpush will skip over that patch when applying patches. You can also change the order in which patches are applied by reordering their entries in the series file.

Placing the series file under revision control is also supported; it is a good idea to place all of the patches that it refers to under revision control, as well. If you create a patch directory using the -c option to qinit, this will be done for you automatically.

The status file contains the names and changeset hashes of all patches that MQ currently has applied. Unlike the series file, this file is not intended for editing. You should not place this file under revision control, or modify it in any way. It is used by MQ strictly for internal book-keeping.
