|
1. Introduction *sign-intro* *signs*
|
|
|
|
When a debugger or other IDE tool is driving an editor it needs to be able
|
|
to give specific highlights which quickly tell the user useful information
|
|
about the file. One example of this would be a debugger which had an icon
|
|
in the left-hand column denoting a breakpoint. Another example might be an
|
|
arrow representing the Program Counter (PC). The sign features allow both
|
|
placement of a sign, or icon, in the left-hand side of the window and
|
|
definition of a highlight which will be applied to that line. Displaying the
|
|
sign as an image is most likely only feasible in gvim (although Sun
|
|
Microsystem's dtterm does support this it's the only terminal emulator I know
|
|
of which does). A text sign and the highlight should be feasible in any color
|
|
terminal emulator.
|
|
|
|
Signs and highlights are not useful just for debuggers. Sun's Visual
|
|
WorkShop uses signs and highlights to mark build errors and SourceBrowser
|
|
hits. Additionally, the debugger supports 8 to 10 different signs and
|
|
highlight colors. |workshop| Same for Netbeans |netbeans|.
|
|
|
|
There are two steps in using signs:
|
|
|
|
1. Define the sign. This specifies the image, text and highlighting. For
|
|
example, you can define a "break" sign with an image of a stop roadsign and
|
|
text "!!".
|
|
|
|
2. Place the sign. This specifies the file and line number where the sign is
|
|
displayed. A defined sign can be placed several times in different lines
|
|
and files.
|
|
|
|
When signs are defined for a file, Vim will automatically add a column of two
|
|
characters to display them in. When the last sign is unplaced the column
|
|
disappears again. The color of the column is set with the SignColumn group
|
|
|hl-SignColumn|. Example to set the color: >
|
|
|
|
:highlight SignColumn guibg=darkgrey
|
|
|
|
==============================================================================
|
|
2. Commands *sign-commands* *:sig* *:sign*
|
|
|
|
Here is an example that places a sign "piet", displayed with the text ">>", in
|
|
line 23 of the current file: >
|
|
:sign define piet text=>> texthl=Search
|
|
:exe ":sign place 2 line=23 name=piet file=" . expand("%:p")
|
|
|
|
And here is the command to delete it again: >
|
|
:sign unplace 2
|
|
|
|
Note that the ":sign" command cannot be followed by another command or a
|
|
comment. If you do need that, use the |:execute| command.
|
|
|
|
|
|
DEFINING A SIGN. *:sign-define* *E255* *E160* *E612*
|
|
|
|
:sign define {name} {argument}...
|
|
Define a new sign or set attributes for an existing sign.
|
|
The {name} can either be a number (all digits) or a name
|
|
starting with a non-digit. Leading digits are ignored, thus
|
|
"0012", "012" and "12" are considered the same name.
|
|
About 120 different signs can be defined.
|
|
|
|
Accepted arguments:
|
|
|
|
icon={bitmap}
|
|
Define the file name where the bitmap can be found. Should be
|
|
a full path. The bitmap should fit in the place of two
|
|
characters. This is not checked. If the bitmap is too big it
|
|
will cause redraw problems. Only GTK 2 can scale the bitmap
|
|
to fit the space available.
|
|
toolkit supports ~
|
|
GTK 1 pixmap (.xpm)
|
|
GTK 2 many
|
|
Motif pixmap (.xpm)
|
|
Win32 .bmp, .ico, .cur
|
|
pixmap (.xpm) |+xpm_w32|
|
|
|
|
linehl={group}
|
|
Highlighting group used for the whole line the sign is placed
|
|
in. Most useful is defining a background color.
|
|
|
|
text={text} *E239*
|
|
Define the text that is displayed when there is no icon or the
|
|
GUI is not being used. Only printable characters are allowed
|
|
and they must occupy one or two display cells.
|
|
|
|
texthl={group}
|
|
Highlighting group used for the text item.
|
|
|
|
|
|
DELETING A SIGN *:sign-undefine* *E155*
|
|
|
|
:sign undefine {name}
|
|
Deletes a previously defined sign. If signs with this {name}
|
|
are still placed this will cause trouble.
|
|
|
|
|
|
LISTING SIGNS *:sign-list* *E156*
|
|
|
|
:sign list Lists all defined signs and their attributes.
|
|
|
|
:sign list {name}
|
|
Lists one defined sign and its attributes.
|
|
|
|
|
|
PLACING SIGNS *:sign-place* *E158*
|
|
|
|
:sign place {id} line={lnum} name={name} file={fname}
|
|
Place sign defined as {name} at line {lnum} in file {fname}.
|
|
*:sign-fname*
|
|
The file {fname} must already be loaded in a buffer. The
|
|
exact file name must be used, wildcards, $ENV and ~ are not
|
|
expanded, white space must not be escaped. Trailing white
|
|
space is ignored.
|
|
|
|
The sign is remembered under {id}, this can be used for
|
|
further manipulation. {id} must be a number.
|
|
It's up to the user to make sure the {id} is used only once in
|
|
each file (if it's used several times unplacing will also have
|
|
to be done several times and making changes may not work as
|
|
expected).
|
|
|
|
:sign place {id} line={lnum} name={name} buffer={nr}
|
|
Same, but use buffer {nr}.
|
|
|
|
:sign place {id} name={name} file={fname}
|
|
Change the placed sign {id} in file {fname} to use the defined
|
|
sign {name}. See remark above about {fname} |:sign-fname|.
|
|
This can be used to change the displayed sign without moving
|
|
it (e.g., when the debugger has stopped at a breakpoint).
|
|
|
|
:sign place {id} name={name} buffer={nr}
|
|
Same, but use buffer {nr}.
|
|
|
|
|
|
REMOVING SIGNS *:sign-unplace* *E159*
|
|
|
|
:sign unplace {id} file={fname}
|
|
Remove the previously placed sign {id} from file {fname}.
|
|
See remark above about {fname} |:sign-fname|.
|
|
|
|
:sign unplace * file={fname}
|
|
Remove all placed signs in file {fname}.
|
|
|
|
:sign unplace {id} buffer={nr}
|
|
Remove the previously placed sign {id} from buffer {nr}.
|
|
|
|
:sign unplace * buffer={nr}
|
|
Remove all placed signs in buffer {nr}.
|
|
|
|
:sign unplace {id}
|
|
Remove the previously placed sign {id} from all files it
|
|
appears in.
|
|
|
|
:sign unplace *
|
|
Remove all placed signs.
|
|
|
|
:sign unplace
|
|
Remove the placed sign at the cursor position.
|
|
|
|
|
|
LISTING PLACED SIGNS
|
|
|
|
:sign place file={fname}
|
|
List signs placed in file {fname}.
|
|
See remark above about {fname} |:sign-fname|.
|
|
|
|
:sign place buffer={nr}
|
|
List signs placed in buffer {nr}.
|
|
|
|
:sign place List placed signs in all files.
|
|
|
|
|
|
JUMPING TO A SIGN *:sign-jump* *E157*
|
|
|
|
:sign jump {id} file={fname}
|
|
Open the file {fname} or jump to the window that contains
|
|
{fname} and position the cursor at sign {id}.
|
|
See remark above about {fname} |:sign-fname|.
|
|
If the file isn't displayed in window and the current file can
|
|
not be |abandon|ed this fails.
|
|
|
|
:sign jump {id} buffer={nr}
|
|
Same, but use buffer {nr}.
