| Some keywords support filters. Filters can be chained when it makes | |
| sense to do so. When in doubt, try it! | |
| bookmark | |
| Display the current bookmark (requires the bookmarks extension). | |
| branch | |
| Display the current branch. | |
| |quiet | |
| Display the current branch only if it is not the default branch. | |
| closed | |
| Display `X` if working on a closed branch (i.e. committing now would reopen | |
| the branch). | |
| count | |
| Display the number of revisions in the given revset (the revset `all()` | |
| will be used if none is given). | |
| See `hg help revsets` for more information. | |
| |REVSET | |
| The revset to count. | |
| incoming | |
| Display nothing, but if the default path contains incoming changesets the | |
| extra text will be expanded. | |
| For example: `{incoming changes{incoming}}` will expand to | |
| `incoming changes` if there are changes, otherwise nothing. | |
| Checking for incoming changesets is an expensive operation, so `hg-prompt` | |
| will cache the results in `.hg/prompt/cache/` and refresh them every 15 | |
| minutes. | |
| |count | |
| Display the number of incoming changesets (if greater than 0). | |
| node | |
| Display the (full) changeset hash of the current parent. | |
| |short | |
| Display the hash as the short, 12-character form. | |
| |merge | |
| Display the hash of the changeset you're merging with. | |
| outgoing | |
| Display nothing, but if the current repository contains outgoing | |
| changesets (to default) the extra text will be expanded. | |
| For example: `{outgoing changes{outgoing}}` will expand to | |
| `outgoing changes` if there are changes, otherwise nothing. | |
| Checking for outgoing changesets is an expensive operation, so `hg-prompt` | |
| will cache the results in `.hg/prompt/cache/` and refresh them every 15 | |
| minutes. | |
| |count | |
| Display the number of outgoing changesets (if greater than 0). | |
| patch | |
| Display the topmost currently-applied patch (requires the mq | |
| extension). | |
| |count | |
| Display the number of patches in the queue. | |
| |topindex | |
| Display (zero-based) index of the topmost applied patch in the series | |
| list (as displayed by :hg:`qtop -v`), or the empty string if no patch | |
| is applied. | |
| |applied | |
| Display the number of currently applied patches in the queue. | |
| |unapplied | |
| Display the number of currently unapplied patches in the queue. | |
| |quiet | |
| Display a number only if there are any patches in the queue. | |
| patches | |
| Display a list of the current patches in the queue. It will look like | |
| this: | |
| :::console | |
| $ hg prompt '{patches}' | |
| bottom-patch -> middle-patch -> top-patch | |
| |reverse | |
| Display the patches in reverse order (i.e. topmost first). | |
| |hide_applied | |
| Do not display applied patches. | |
| |hide_unapplied | |
| Do not display unapplied patches. | |
| |join(SEP) | |
| Display SEP between each patch, instead of the default ` -> `. | |
| |pre_applied(STRING) | |
| Display STRING immediately before each applied patch. Useful for | |
| adding color codes. | |
| |post_applied(STRING) | |
| Display STRING immediately after each applied patch. Useful for | |
| resetting color codes. | |
| |pre_unapplied(STRING) | |
| Display STRING immediately before each unapplied patch. Useful for | |
| adding color codes. | |
| |post_unapplied(STRING) | |
| Display STRING immediately after each unapplied patch. Useful for | |
| resetting color codes. | |
| queue | |
| Display the name of the current MQ queue. | |
| rev | |
| Display the repository-local changeset number of the current parent. | |
| |merge | |
| Display the repository-local changeset number of the changeset you're | |
| merging with. | |
| root | |
| Display the full path to the root of the current repository, without a | |
| trailing slash. | |
| |basename | |
| Display the directory name of the root of the current repository. For | |
| example, if the repository is in `/home/u/myrepo` then this keyword | |
| would expand to `myrepo`. | |
| status | |
| Display `!` if the repository has any changed/added/removed files, | |
| otherwise `?` if it has any untracked (but not ignored) files, otherwise | |
| nothing. | |
| |modified | |
| Display `!` if the current repository contains files that have been | |
| modified, added, removed, or deleted, otherwise nothing. | |
| |unknown | |
| Display `?` if the current repository contains untracked files, | |
| otherwise nothing. | |
| tags | |
| Display the tags of the current parent, separated by a space. | |
| |quiet | |
| Display the tags of the current parent, excluding the tag "tip". | |
| |SEP | |
| Display the tags of the current parent, separated by `SEP`. | |
| task | |
| Display the current task (requires the tasks extension). | |
| tip | |
| Display the repository-local changeset number of the current tip. | |
| |node | |
| Display the (full) changeset hash of the current tip. | |
| |short | |
| Display a short form of the changeset hash of the current tip (must be | |
| used with the **|node** filter) | |
| update | |
| Display `^` if the current parent is not the tip of the current branch, | |
| otherwise nothing. In effect, this lets you see if running `hg update` | |
| would do something. | |
