1. Intro *NERDCommenter*
|
|
|
|
The NERD commenter provides many different commenting operations and styles
|
|
which are invoked via key mappings and a menu. These operations are available
|
|
for most filetypes.
|
|
|
|
There are also options that allow to tweak the commenting engine to your
|
|
taste.
|
|
|
|
==============================================================================
|
|
2. Installation *NERDComInstallation*
|
|
|
|
The NERD Commenter requires Vim 7 or higher.
|
|
|
|
Extract the plugin files in your ~/.vim (*nix) or ~/vimfiles (Windows). You
|
|
should have 2 files: >
|
|
plugin/NERD_commenter.vim
|
|
doc/NERD_commenter.txt
|
|
<
|
|
Next, to finish installing the help file run: >
|
|
:helptags ~/.vim/doc
|
|
<
|
|
See |add-local-help| for more details.
|
|
|
|
Make sure that you have filetype plugins enabled, as the script makes use of
|
|
|'commentstring'| where possible (which is usually set in a filetype plugin).
|
|
See |filetype-plugin-on| for details, but basically, stick this in your vimrc >
|
|
filetype plugin on
|
|

|
|
3.1 Functionality summary *NERDComFunctionalitySummary*
|
|
|
|
The following key mappings are provided by default (there is also a menu
|
|
with items corresponding to all the mappings below):
|
|
|

|
|
|
|
|
|
[count]|<Leader>|c<space> |NERDComToggleComment|

|
|<Leader>|c$ |NERDComEOLComment|
|
|
Comments the current line from the cursor to the end of line.
|
|
|
|
|
|
|<Leader>|cA |NERDComAppendComment|

Adds comment delimiters to the end of line and goes into insert mode between
|
|
them.
|
|
|
|
|
|
|NERDComInsertComment|
|
|
Adds comment delimiters at the current cursor position and inserts between.
|
|
Disabled by default.
|
|
|
|
|
|
|<Leader>|ca |NERDComAltDelim|

|
|
|
|
|
|
[count]|<Leader>|cl
|
|
[count]|<Leader>|cb |NERDComAlignedComment|
|
|
Same as |NERDComComment| except that the delimiters are aligned down the
|
|
left side (|<Leader>|cl) or both sides (|<Leader>|cb).
|
|
|
|
|
|
[count]|<Leader>|cu |NERDComUncommentLine|
|
|
Uncomments the selected line(s).
|
|
|
|
|
|
With the optional repeat.vim plugin (vimscript #2136), the mappings can also
|
|
be repeated via |.|

|
3.2 Functionality details *NERDComFunctionalityDetails*
|
|
|
|
------------------------------------------------------------------------------
|
|
3.2.1 Comment map *NERDComComment*
|
|
|
|
Default mapping: [count]|<Leader>|cc
|
|
Mapped to: <plug>NERDCommenterComment
|
|
Applicable modes: normal visual visual-line visual-block.
|
|
|
|
|
|
Comments out the current line. If multiple lines are selected in visual-line
|
|
mode, they are all commented out. If some text is selected in visual or
|
|
visual-block mode then the script will try to comment out the exact text that
|
|
is selected using multi-part delimiters if they are available.
|
|
|
|
If a [count] is given in normal mode, the mapping works as though that many
|
|
lines were selected in visual-line mode.
|
|
|
|
------------------------------------------------------------------------------
|
|
3.2.2 Nested comment map *NERDComNestedComment*
|
|
|
|
Default mapping: [count]|<Leader>|cn
|
|
Mapped to: <plug>NERDCommenterNested
|
|
Applicable modes: normal visual visual-line visual-block.
|
|
|
|
Performs nested commenting. Works the same as |<Leader>|cc except that if a line
|
|
is already commented then it will be commented again.
|
|
|
|
If |'NERDUsePlaceHolders'| is set then the previous comment delimiters will
|
|
be replaced by place-holder delimiters if needed. Otherwise the nested
|
|
comment will only be added if the current commenting delimiters have no right
|
|
delimiter (to avoid syntax errors)
|
|
|
|
If a [count] is given in normal mode, the mapping works as though that many
|
|
lines were selected in visual-line mode.
|
|
|
|
Related options:
|
|
|'NERDDefaultNesting'|
|
|
|
|
------------------------------------------------------------------------------
|
|
3.2.3 Toggle comment map *NERDComToggleComment*
|
|
|
|
Default mapping: [count]|<Leader>|c<space>
|
|
Mapped to: <plug>NERDCommenterToggle
|
|
Applicable modes: normal visual-line.
|
|
|
|
Toggles commenting of the lines selected. The behaviour of this mapping
|
|
depends on whether the first line selected is commented or not. If so, all
|
|
selected lines are uncommented and vice versa.
|
|
|
|
With this mapping, a line is only considered to be commented if it starts with
|
|
a left delimiter.
|
|
|
|
If a [count] is given in normal mode, the mapping works as though that many
|
|
lines were selected in visual-line mode.
|
|
|
|
------------------------------------------------------------------------------
|
|
3.2.4 Minimal comment map *NERDComMinimalComment*
|
|
|
|
Default mapping: [count]|<Leader>|cm
|
|
Mapped to: <plug>NERDCommenterMinimal
|
|
Applicable modes: normal visual-line.
|
|
|
|
Comments the selected lines using one set of multipart delimiters if possible.
|
|
|
|
For example: if you are programming in c and you select 5 lines and press
|
|
|<Leader>|cm then a '/*' will be placed at the start of the top line and a '*/'
|
|
will be placed at the end of the last line.
|
|
|
|
Sets of multipart comment delimiters that are between the top and bottom
|
|
selected lines are replaced with place holders (see |'NERDLPlace'|) if
|
|
|'NERDUsePlaceHolders'| is set for the current filetype. If it is not, then
|
|
the comment will be aborted if place holders are required to prevent illegal
|
|
syntax.
|
|
|
|
If a [count] is given in normal mode, the mapping works as though that many
|
|
lines were selected in visual-line mode.
|
|
|
|
------------------------------------------------------------------------------
|
|
3.2.5 Invert comment map *NERDComInvertComment*
|
|
|
|
Default mapping: |<Leader>|ci
|
|
Mapped to: <plug>NERDCommenterInvert
|
|
Applicable modes: normal visual-line.
|
|
|
|
Inverts the commented state of each selected line. If the a selected line is
|
|
commented then it is uncommented and vice versa. Each line is examined and
|
|
commented/uncommented individually.
|
|
|
|
With this mapping, a line is only considered to be commented if it starts with
|
|
a left delimiter.
|
|
|
|
If a [count] is given in normal mode, the mapping works as though that many
|
|
lines were selected in visual-line mode.
|
|
|
|
------------------------------------------------------------------------------
|
|
3.2.6 Sexy comment map *NERDComSexyComment*
|
|
|
|
Default mapping: [count]|<Leader>|cs
|
|
Mapped to: <plug>NERDCommenterSexy
|
|
Applicable modes: normal, visual-line.
|
|
|
|
Comments the selected line(s) ``sexily''... see |NERDComSexyComments| for
|
|
a description of what sexy comments are. Can only be done on filetypes for
|
|
which there is at least one set of multipart comment delimiters specified.
|
|
|
|
Sexy comments cannot be nested and lines inside a sexy comment cannot be
|
|
commented again.
|
|
|
|
If a [count] is given in normal mode, the mapping works as though that many
|
|
lines were selected in visual-line mode.
|
|
|
|

3.2.7 Yank comment map *NERDComYankComment*
|
|
|
|
Default mapping: [count]|<Leader>|cy
|
|
Mapped to: <plug>NERDCommenterYank
|
|
Applicable modes: normal visual visual-line visual-block.
|
|
|
|
Same as |<Leader>|cc except that it yanks the line(s) that are commented first.
|
|
|
|
------------------------------------------------------------------------------
|
|
3.2.8 Comment to EOL map *NERDComEOLComment*
|
|
|
|
Default mapping: |<Leader>|c$
|
|
Mapped to: <plug>NERDCommenterToEOL
|
|
Applicable modes: normal.
|
|
|
|
Comments the current line from the current cursor position up to the end of
|
|
the line.
|
|
|
|
------------------------------------------------------------------------------
|
|
3.2.9 Append com to line map *NERDComAppendComment*
|
|
|
|
Default mapping: |<Leader>|cA
|
|
Mapped to: <plug>NERDCommenterAppend
|
|
Applicable modes: normal.
|
|
|
|
Appends comment delimiters to the end of the current line and goes
|
|
to insert mode between the new delimiters.
|
|
|
|
------------------------------------------------------------------------------
|
|
3.2.10 Insert comment map *NERDComInsertComment*
|
|
|
|
Default mapping: disabled by default.
|
|
Map it to: <plug>NERDCommenterInsert
|
|
Applicable modes: insert.
|
|
|
|
Adds comment delimiters at the current cursor position and inserts
|
|
between them.
|
|
|
|
NOTE: prior to version 2.1.17 this was mapped to ctrl-c. To restore this
|
|
mapping add >
|
|
let NERDComInsertMap='<c-c>'
|
|
<
|
|
to your vimrc.
|
|
|
|
------------------------------------------------------------------------------
|
|
3.2.11 Use alternate delims map *NERDComAltDelim*
|
|
|
|
Default mapping: |<Leader>|ca
|
|
Mapped to: <plug>NERDCommenterAltDelims
|
|
Applicable modes: normal.
|
|
|
|
Changes to the alternative commenting style if one is available. For example,
|
|
if the user is editing a c++ file using // comments and they hit |<Leader>|ca
|
|
then they will be switched over to /**/ comments.
|
|
|
|
See also |NERDComDefaultDelims|
|
|
|
|
------------------------------------------------------------------------------
|
|
3.2.12 Comment aligned maps *NERDComAlignedComment*
|
|
|
|
Default mappings: [count]|<Leader>|cl [count]|<Leader>|cb
|
|
Mapped to: <plug>NERDCommenterAlignLeft
|
|
<plug>NERDCommenterAlignBoth
|
|
Applicable modes: normal visual-line.
|
|
|
|
Same as |<Leader>|cc except that the comment delimiters are aligned on the left
|
|
side or both sides respectively. These comments are always nested if the
|
|
line(s) are already commented.
|
|
|
|
If a [count] is given in normal mode, the mapping works as though that many
|
|
lines were selected in visual-line mode.
|
|
|
|
------------------------------------------------------------------------------
|
|
3.2.13 Uncomment line map *NERDComUncommentLine*
|
|
|
|
Default mapping: [count]|<Leader>|cu
|
|
Mapped to: <plug>NERDCommenterUncomment
|
|
Applicable modes: normal visual visual-line visual-block.
|
|
|
|
Uncomments the current line. If multiple lines are selected in
|
|
visual mode then they are all uncommented.
|
|
|
|
When uncommenting, if the line contains multiple sets of delimiters then the
|
|
``outtermost'' pair of delimiters will be removed.
|
|
|
|
The script uses a set of heurisics to distinguish ``real'' delimiters from
|
|
``fake'' ones when uncommenting. See |NERDComIssues| for details.
|
|
|
|
If a [count] is given in normal mode, the mapping works as though that many
|
|
lines were selected in visual-line mode.

|
|
3.3 Sexy Comments *NERDComSexyComments*
|
|
These are comments that use one set of multipart comment delimiters as well as
|
|
one other marker symbol. For example: >
|
|
/*
|
|
* This is a c style sexy comment
|
|
* So there!
|
|
*/
|
|
|
|
/* This is a c style sexy comment
|
|
* So there!
|
|
* But this one is ``compact'' style */
|
|
<
|
|
Here the multipart delimiters are /* and */ and the marker is *.
|
|
|
|
------------------------------------------------------------------------------
|
|
3.4 The NERDComment function *NERDComNERDComment*
|
|
|
|
All of the NERD commenter mappings and menu items invoke a single function
|
|
which delegates the commenting work to other functions. This function is
|
|
public and has the prototype: >
|
|
function! NERDComment(mode, type)
|
|
<
|
|
The arguments to this function are simple:
|
|
- mode: a character indicating the mode in which the comment is requested:
|
|
'n' for Normal mode, 'x' for Visual mode
|
|
- type: is used to specify what type of commenting operation is to be
|
|
performed, and it can be one of the following: "sexy", "invert",
|
|
"minimal", "toggle", "alignLeft", "alignBoth", "comment", "nested",
|
|
"toEOL", "append", "insert", "uncomment", "yank"
|
|
|
|
For example, if you typed >
|
|
:call NERDComment(1, 'sexy')
|
|
<
|
|
then the script would do a sexy comment on the last visual selection.
|

|
|
------------------------------------------------------------------------------
|
|
4.3 Options details *NERDComOptionsDetails*
|
|
|
|
To enable any of the below options you should put the given line in your
|
|
~/.vimrc
|
|
|
|
*'loaded_nerd_comments'*
|
|
If this script is driving you insane you can turn it off by setting this
|
|
option >
|
|
let loaded_nerd_comments=1
|
|
<
|
|
------------------------------------------------------------------------------
|
|
*'NERDAllowAnyVisualDelims'*
|
|
Values: 0 or 1.
|
|
Default: 1.
|
|
|
|
If set to 1 then, when doing a visual or visual-block comment (but not a
|
|
visual-line comment), the script will choose the right delimiters to use for
|
|
the comment. This means either using the current delimiters if they are
|
|
multipart or using the alternative delimiters if THEY are multipart. For
|
|
example if we are editing the following java code: >
|
|
float foo = 1221;
|
|
float bar = 324;
|
|
System.out.println(foo * bar);
|
|
<
|
|
If we are using // comments and select the "foo" and "bar" in visual-block
|
|
mode, as shown left below (where '|'s are used to represent the visual-block
|
|
boundary), and comment it then the script will use the alternative delims as
|
|
shown on the right: >
|
|
|
|
float |foo| = 1221; float /*foo*/ = 1221;
|
|
float |bar| = 324; float /*bar*/ = 324;
|
|
System.out.println(foo * bar); System.out.println(foo * bar);
|
|
<
|
|
------------------------------------------------------------------------------
|
|
*'NERDBlockComIgnoreEmpty'*
|
|
Values: 0 or 1.
|
|
Default: 1.
|
|
|
|
This option affects visual-block mode commenting. If this option is turned
|
|
on, lines that begin outside the right boundary of the selection block will be
|
|
ignored.
|
|
|
|
For example, if you are commenting this chunk of c code in visual-block mode
|
|
(where the '|'s are used to represent the visual-block boundary) >
|
|
#include <sys/types.h>
|
|
#include <unistd.h>
|
|
#include <stdio.h>
|
|
|int| main(){
|
|
| | printf("SUCK THIS\n");
|
|
| | while(1){
|
|
| | fork();
|
|
| | }
|
|
|} |
|
|
<
|
|
If NERDBlockComIgnoreEmpty=0 then this code will become: >
|
|
#include <sys/types.h>
|
|
#include <unistd.h>
|
|
#include <stdio.h>
|
|
/*int*/ main(){
|
|
/* */ printf("SUCK THIS\n");
|
|
/* */ while(1){
|
|
/* */ fork();
|
|
/* */ }
|
|
/*} */
|
|
<
|
|
Otherwise, the code block would become: >
|
|
#include <sys/types.h>
|
|
#include <unistd.h>
|
|
#include <stdio.h>
|
|
/*int*/ main(){
|
|
printf("SUCK THIS\n");
|
|
while(1){
|
|
fork();

|
|
*'NERDCommentWholeLinesInVMode'*
|
|
Values: 0, 1 or 2.
|
|
Default: 0.
|
|
|
|
By default the script tries to comment out exactly what is selected in visual
|
|
mode (v). For example if you select and comment the following c code (using |
|
|
to represent the visual boundary): >
|
|
in|t foo = 3;
|
|
int bar =| 9;
|
|
int baz = foo + bar;
|
|
<
|
|
This will result in: >
|
|
in/*t foo = 3;*/
|
|
/*int bar =*/ 9;
|
|
int baz = foo + bar;
|
|
<
|
|
But some people prefer it if the whole lines are commented like: >
|
|
/*int foo = 3;*/
|
|
/*int bar = 9;*/
|
|
int baz = foo + bar;
|
|
<
|
|
If you prefer the second option then stick this line in your vimrc: >
|
|
let NERDCommentWholeLinesInVMode=1
|
|
<
|
|
|
|
If the filetype you are editing only has no multipart delimiters (for example
|
|
a shell script) and you hadnt set this option then the above would become >
|
|
in#t foo = 3;
|
|
#int bar = 9;
|
|
<
|
|
(where # is the comment delimiter) as this is the closest the script can
|
|
come to commenting out exactly what was selected. If you prefer for whole
|
|
lines to be commented out when there is no multipart delimiters but the EXACT
|
|
text that was selected to be commented out if there IS multipart delimiters
|
|
then stick the following line in your vimrc: >
|
|
let NERDCommentWholeLinesInVMode=2
|
|
<
|
|
|
|
Note that this option does not affect the behaviour of commenting in
|
|
|visual-block| mode.
|
|
|
|
------------------------------------------------------------------------------
|
|
*'NERDCreateDefaultMappings'*
|
|
Values: 0 or 1.
|
|
Default: 1.
|
|
|
|
If set to 0, none of the default mappings will be created.
|
|
|
|
See also |NERDComMappings|.
|
|
|
|
------------------------------------------------------------------------------
|
|
*'NERDCustomDelimiters'*
|
|
Values: A map (format specified below).
|
|
Default: {}
|
|
|
|
Use this option if you have new filetypes you want the script to handle, or if
|
|
you want to override the default delimiters of a filetype.
|
|
|
|
Example: >
|
|
let g:NERDCustomDelimiters = {
|
|
\ 'ruby': { 'left': '#', 'leftAlt': 'FOO', 'rightAlt': 'BAR' },
|
|
\ 'grondle': { 'left': '{{', 'right': '}}' }
|
|
\ }
|
|
<
|
|
|
|
Here we override the delimiter settings for ruby and add FOO/BAR as alternative
|
|
delimiters. We also add {{ and }} as delimiters for a new filetype called
|
|
'grondle'.
|
|
|
|
------------------------------------------------------------------------------
|
|
*'NERDRemoveAltComs'*
|
|
Values: 0 or 1.
|
|
Default: 1.
|
|
|
|
When uncommenting a line (for a filetype with an alternative commenting style)
|
|
this option tells the script whether to look for, and remove, comment
|
|
delimiters of the alternative style.
|
|
|
|
For example, if you are editing a c++ file using // style comments and you go
|
|
|<Leader>|cu on this line: >
|
|
/* This is a c++ comment baby! */
|
|
<
|
|
It will not be uncommented if the NERDRemoveAltComs is set to 0.
|
|
|
|
------------------------------------------------------------------------------
|
|
*'NERDRemoveExtraSpaces'*
|
|
Values: 0 or 1.
|
|
Default: 0.
|
|
|
|
By default, the NERD commenter will remove spaces around comment delimiters if
|
|
either:
|
|
1. |'NERDSpaceDelims'| is set to 1.
|
|
2. NERDRemoveExtraSpaces is set to 1.
|
|
|
|
This means that if we have the following lines in a c code file: >
|
|
/* int foo = 5; */
|
|
/* int bar = 10; */
|
|
int baz = foo + bar
|
|
<
|
|
If either of the above conditions hold then if these lines are uncommented
|
|
they will become: >
|
|
int foo = 5;
|
|
int bar = 10;
|
|
int baz = foo + bar
|
|
<
|
|
Otherwise they would become: >
|
|
int foo = 5;
|
|
int bar = 10;
|
|
int baz = foo + bar
|
|
<
|
|
|
|
------------------------------------------------------------------------------
|
|
*'NERDLPlace'*
|
|
*'NERDRPlace'*
|
|
Values: arbitrary string.
|
|
Default:
|
|
NERDLPlace: "[>"
|
|
NERDRPlace: "<]"
|
|
|
|
These options are used to control the strings used as place-holder delimiters.
|
|
Place holder delimiters are used when performing nested commenting when the
|
|
filetype supports commenting styles with both left and right delimiters.
|
|
To set these options use lines like: >
|
|
let NERDLPlace="FOO"
|
|
let NERDRPlace="BAR"
|
|
<
|
|
Following the above example, if we have line of c code: >
|
|
/* int horse */
|
|
<
|
|
and we comment it with |<Leader>|cn it will be changed to: >
|
|
/*FOO int horse BAR*/
|
|
<
|
|
When we uncomment this line it will go back to what it was.
|
|
|
|
------------------------------------------------------------------------------
|
|
*'NERDMenuMode'*
|
|
Values: 0, 1, 2, 3.
|
|
Default: 3
|
|
|
|
This option can take 4 values:
|
|
"0": Turns the menu off.
|
|
"1": Turns the 'comment' menu on with no menu shortcut.
|
|
"2": Turns the 'comment' menu on with <alt>-c as the shortcut.
|
|
"3": Turns the 'Plugin -> comment' menu on with <alt>-c as the shortcut.
|
|
|
|
------------------------------------------------------------------------------
|
|
*'NERDUsePlaceHolders'*
|
|
Values: 0 or 1.
|
|
Default 1.
|
|
|
|
This option is used to specify whether place-holder delimiters should be used
|
|
when creating a nested comment.
|
|
|
|
------------------------------------------------------------------------------
|
|
*'NERDSpaceDelims'*
|
|
Values: 0 or 1.
|
|
Default 0.
|
|
|
|
Some people prefer a space after the left delimiter and before the right
|
|
delimiter like this: >
|
|
/* int foo=2; */
|
|
<
|
|
as opposed to this: >
|
|
/*int foo=2;*/
|
|
<
|
|
If you want spaces to be added then set NERDSpaceDelims to 1 in your vimrc.
|
|
|
|
See also |'NERDRemoveExtraSpaces'|.
|
|
|
|
------------------------------------------------------------------------------
|
|
*'NERDCompactSexyComs'*
|
|
Values: 0 or 1.
|
|
Default 0.
|
|
|
|
Some people may want their sexy comments to be like this: >
|
|
/* Hi There!
|
|
* This is a sexy comment
|
|
* in c */
|
|
<
|
|
As opposed to like this: >
|
|
/*
|
|
* Hi There!
|
|
* This is a sexy comment
|
|
* in c
|
|
*/
|
|
<
|
|
If this option is set to 1 then the top style will be used.
|
|
|
|
------------------------------------------------------------------------------
|
|
*'NERDDefaultNesting'*
|
|
Values: 0 or 1.
|
|
Default 1.
|
|
|
|
When this option is set to 1, comments are nested automatically. That is, if
|
|
you hit |<Leader>|cc on a line that is already commented it will be commented
|
|
again.
|
|
|
|
------------------------------------------------------------------------------
|
|
3.3 Default delimiter customisation *NERDComDefaultDelims*
|
|
|
|
If you want the NERD commenter to use the alternative delimiters for a
|
|
specific filetype by default then put a line of this form into your vimrc: >
|
|
let NERD_<filetype>_alt_style=1
|
|
<
|
|
Example: java uses // style comments by default, but you want it to default to
|
|
/* */ style comments instead. You would put this line in your vimrc: >
|
|
let NERD_java_alt_style=1
|
|
<
|
|
|
|
See |NERDComAltDelim| for switching commenting styles at runtime.
|
|
|
|
==============================================================================
|
|
5. Key mapping customisation *NERDComMappings*
|
|
|
|
To change a mapping just map another key combo to the internal <plug> mapping.
|
|
For example, to remap the |NERDComComment| mapping to ",omg" you would put
|
|
this line in your vimrc: >
|
|
map ,omg <plug>NERDCommenterComment
|
|
<
|
|
This will stop the corresponding default mappings from being created.
|
|
|
|
See the help for the mapping in question to see which <plug> mapping to
|
|
map to.
|
|
|
|
See also |'NERDCreateDefaultMappings'|.
|
|
|
|
==============================================================================
|
|
6. Issues with the script *NERDComIssues*
|
|
|
|
|
|
------------------------------------------------------------------------------
|
|
6.1 Delimiter detection heuristics *NERDComHeuristics*
|
|
|
|
Heuristics are used to distinguish the real comment delimiters
|
|
|
|
Because we have comment mappings that place delimiters in the middle of lines,
|
|
removing comment delimiters is a bit tricky. This is because if comment
|
|
delimiters appear in a line doesnt mean they really ARE delimiters. For
|
|
example, Java uses // comments but the line >
|
|
System.out.println("//");
|
|
<
|
|
clearly contains no real comment delimiters.
|
|
|
|
To distinguish between ``real'' comment delimiters and ``fake'' ones we use a
|
|
set of heuristics. For example, one such heuristic states that any comment
|
|
delimiter that has an odd number of non-escaped " characters both preceding
|
|
and following it on the line is not a comment because it is probably part of a
|
|
string. These heuristics, while usually pretty accurate, will not work for all
|
|
cases.
|
|
|
|
------------------------------------------------------------------------------
|
|
6.2 Nesting issues *NERDComNesting*
|
|
|
|
If we have some line of code like this: >
|
|
/*int foo */ = /*5 + 9;*/
|
|
<
|
|
This will not be uncommented legally. The NERD commenter will remove the
|
|
"outter most" delimiters so the line will become: >
|
|
int foo */ = /*5 + 9;
|
|
<
|
|
which almost certainly will not be what you want. Nested sets of comments will
|
|
uncomment fine though. Eg: >
|
|
/*int/* foo =*/ 5 + 9;*/
|
|
<
|
|
will become: >
|
|
int/* foo =*/ 5 + 9;
|
|
<
|
|
(Note that in the above examples I have deliberately not used place holders
|
|
for simplicity)
|
|
|
