.fi
.sp

.SH DESCRIPTION
.sp
The fish_hg_prompt function displays information about the current Mercurial repository, if any.
.sp
\X'tty: link https://www.mercurial-scm.org/'\fI\%Mercurial\fP <\fBhttps://www.mercurial-scm.org/\fP>\X'tty: link' (\fBhg\fP) must be installed.
.sp
By default, only the current branch is shown because \fBhg status\fP can be slow on a large repository. You can enable a more informative prompt by setting the variable \fB$fish_prompt_hg_show_informative_status\fP, for example:
.INDENT 0.0
.INDENT 3.5
.sp
.EX
set \-\-universal fish_prompt_hg_show_informative_status
.EE
.UNINDENT
.UNINDENT
.sp
If you enabled the informative status, there are numerous customization options, which can be controlled with fish variables.
.INDENT 0.0
.IP \(bu 2
\fB$fish_color_hg_clean\fP, \fB$fish_color_hg_modified\fP and \fB$fish_color_hg_dirty\fP are colors used when the repository has the respective status.
.UNINDENT
.sp
Some colors for status symbols:
.INDENT 0.0
.IP \(bu 2
\fB$fish_color_hg_added\fP
.IP \(bu 2
\fB$fish_color_hg_renamed\fP
.IP \(bu 2
\fB$fish_color_hg_copied\fP
.IP \(bu 2
\fB$fish_color_hg_deleted\fP
.IP \(bu 2
\fB$fish_color_hg_untracked\fP
.IP \(bu 2
\fB$fish_color_hg_unmerged\fP
.UNINDENT
.sp
The status symbols themselves:
.INDENT 0.0
.IP \(bu 2
\fB$fish_prompt_hg_status_added\fP, default \(aq✚\(aq
.IP \(bu 2
\fB$fish_prompt_hg_status_modified\fP, default \(aq*\(aq
.IP \(bu 2
\fB$fish_prompt_hg_status_copied\fP, default \(aq⇒\(aq
.IP \(bu 2
\fB$fish_prompt_hg_status_deleted\fP, default \(aq✖\(aq
.IP \(bu 2
\fB$fish_prompt_hg_status_untracked\fP, default \(aq?\(aq
.IP \(bu 2
\fB$fish_prompt_hg_status_unmerged\fP, default \(aq!\(aq
.UNINDENT
.sp
Finally, \fB$fish_prompt_hg_status_order\fP, which can be used to change the order the status symbols appear in. It defaults to \fBadded modified copied deleted untracked unmerged\fP\&.
