Works the same as ||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]||c +Mapped to: 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]||cm +Mapped to: 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 +||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: ||ci +Mapped to: 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]||cs +Mapped to: NERDCommenterSexy +Applicable modes: normal, visual-line. + +Comments the selected line(s) ``sexily''... see |NERDComSexyComments| for +a description of what sexy comments are.

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]||cu +Mapped to: 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. + +Related options: +|'NERDRemoveAltComs'| +|'NERDRemoveExtraSpaces'| + +------------------------------------------------------------------------------ +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(isVisual, type) +< +The arguments to this function are simple: + - isVisual: if you wish to do any kind of visual comment then set this to + 1 and the function will use the '< and '> marks to find the comment + boundries. If set to 0 then the function will operate on the current + line. + - 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", "norm", "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.

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 + #include + #include + |int| main(){ + | | printf("SUCK THIS\n"); + | | while(1){ + | | fork(); + | | } + |} | +< +If NERDBlockComIgnoreEmpty=0 then this code will become: > + #include + #include + #include + /*int*/ main(){ + /* */ printf("SUCK THIS\n"); + /* */ while(1){ + /* */ fork(); + /* */ } + /*} */ +< +Otherwise, the code block would become: > + #include + #include + #include + /*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 +||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 ||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 -c as the shortcut. + "3": Turns the 'Plugin -> comment' menu on with -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 ||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__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 mapping. +For example, to remap the |NERDComComment| mapping to ",omg" you would put +this line in your vimrc: > + map ,omg NERDCommenterComment +< +This will stop the corresponding default mappings from being created. + +See the help for the mapping in question to see which 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) + +============================================================================== +7.
