20==============================================================================
211. Fold methods *fold-methods*
22
23The folding method can be set with the 'foldmethod' option.
24
25When setting 'foldmethod' to a value other than "manual", all folds are
26deleted and new ones created. Switching to the "manual" method doesn't remove
27the existing folds. This can be used to first define the folds automatically
28and then change them manually.
29
30There are six methods to select folds:
31 manual manually define folds
32 indent more indent means a higher fold level
33 expr specify an expression to define folds
34 syntax folds defined by syntax highlighting
35 diff folds for unchanged text
36 marker folds defined by markers in the text
37
38
39MANUAL *fold-manual*
40
41Use commands to manually define the fold regions. This can also be used by a
42script that parses text to find folds.
43
44The level of a fold is only defined by its nesting. To increase the fold
45level of a fold for a range of lines, define a fold inside it that has the
46same lines.
47
48The manual folds are lost when you abandon the file. To save the folds use
49the |:mkview| command. The view can be restored later with |:loadview|.
50
51
52INDENT *fold-indent*
53
54The folds are automatically defined by the indent of the lines.
55
56The foldlevel is computed from the indent of the line, divided by the
57'shiftwidth' (rounded down). A sequence of lines with the same or higher fold
58level form a fold, with the lines with a higher level forming a nested fold.
59
60The nesting of folds is limited with 'foldnestmax'.
61
62Some lines are ignored and get the fold level of the line above or below it,
Bram Moolenaar446beb42011-05-10 17:18:44 +020063whichever is lower. These are empty or white lines and lines starting
Bram Moolenaar071d4272004-06-13 20:20:40 +000064with a character in 'foldignore'. White space is skipped before checking for
65characters in 'foldignore'. For C use "#" to ignore preprocessor lines.
66
67When you want to ignore lines in another way, use the 'expr' method. The
68|indent()| function can be used in 'foldexpr' to get the indent of a line.
69
70
71EXPR *fold-expr*
72
73The folds are automatically defined by their foldlevel, like with the "indent"
74method. The value of the 'foldexpr' option is evaluated to get the foldlevel
75of a line. Examples:
Bram Moolenaar666771a2007-05-12 14:03:30 +000076This will create a fold for all consecutive lines that start with a tab: >
Bram Moolenaar071d4272004-06-13 20:20:40 +000077 :set foldexpr=getline(v:lnum)[0]==\"\\t\"
78This will call a function to compute the fold level: >
79 :set foldexpr=MyFoldLevel(v:lnum)
80This will make a fold out of paragraphs separated by blank lines: >
81 :set foldexpr=getline(v:lnum)=~'^\\s*$'&&getline(v:lnum+1)=~'\\S'?'<1':1
82this does the same: >
83 :set foldexpr=getline(v:lnum-1)=~'^\\s*$'&&getline(v:lnum)=~'\\S'?'>1':1
84
85Note that backslashes must be used to escape characters that ":set" handles
86differently (space, backslash, double quote, etc., see |option-backslash|).
87
88These are the conditions with which the expression is evaluated:
89- The current buffer and window are set for the line.
90- The variable "v:lnum" is set to the line number.
91- The result is used for the fold level in this way:
92 value meaning ~
93 0 the line is not in a fold
94 1, 2, .. the line is in a fold with this level
95 -1 the fold level is undefined, use the fold level of a
96 line before or after this line, whichever is the
97 lowest.
98 "=" use fold level from the previous line
99 "a1", "a2", .. add one, two, .. to the fold level of the previous
Bram Moolenaard042dc82015-11-24 19:18:36 +0100100 line, use the result for the current line
Bram Moolenaar071d4272004-06-13 20:20:40 +0000101 "s1", "s2", .. subtract one, two, .. from the fold level of the
Bram Moolenaard042dc82015-11-24 19:18:36 +0100102 previous line, use the result for the next line
Bram Moolenaar071d4272004-06-13 20:20:40 +0000103 "<1", "<2", .. a fold with this level ends at this line
104 ">1", ">2", .. a fold with this level starts at this line
105
106It is not required to mark the start (end) of a fold with ">1" ("<1"), a fold
107will also start (end) when the fold level is higher (lower) than the fold
108level of the previous line.
109
110There must be no side effects from the expression. The text in the buffer,
111cursor position, the search patterns, options etc. must not be changed.
Bram Moolenaare2f98b92006-03-29 21:18:24 +0000112You can change and restore them if you are careful.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000113
114If there is some error in the expression, or the resulting value isn't
115recognized, there is no error message and the fold level will be zero.
116For debugging the 'debug' option can be set to "msg", the error messages will
117be visible then.
118
119Note: Since the expression has to be evaluated for every line, this fold
120method can be very slow!
121
122Try to avoid the "=", "a" and "s" return values, since Vim often has to search
123backwards for a line for which the fold level is defined. This can be slow.
124
Bram Moolenaard042dc82015-11-24 19:18:36 +0100125An example of using "a1" and "s1": For a multi-line C comment, a line
126containing "/*" would return "a1" to start a fold, and a line containing "*/"
127would return "s1" to end the fold after that line: >
128 if match(thisline, '/\*') >= 0
129 return 'a1'
130 elseif match(thisline, '\*/') >= 0
131 return 's1'
132 else
133 return '='
134 endif
135However, this won't work for single line comments, strings, etc.
136
Bram Moolenaar071d4272004-06-13 20:20:40 +0000137|foldlevel()| can be useful to compute a fold level relative to a previous
138fold level. But note that foldlevel() may return -1 if the level is not known
139yet. And it returns the level at the start of the line, while a fold might
140end in that line.
141
Bram Moolenaar00a927d2010-05-14 23:24:24 +0200142It may happened that folds are not updated properly. You can use |zx| or |zX|
143to force updating folds.
144
Bram Moolenaar071d4272004-06-13 20:20:40 +0000145
146SYNTAX *fold-syntax*
147
148A fold is defined by syntax items that have the "fold" argument. |:syn-fold|
149
150The fold level is defined by nesting folds. The nesting of folds is limited
151with 'foldnestmax'.
152
153Be careful to specify proper syntax syncing. If this is not done right, folds
154may differ from the displayed highlighting. This is especially relevant when
155using patterns that match more than one line. In case of doubt, try using
156brute-force syncing: >
157 :syn sync fromstart
158
159
160DIFF *fold-diff*
161
162The folds are automatically defined for text that is not part of a change or
163close to a change.
164
165This method only works properly when the 'diff' option is set for the current
166window and changes are being displayed. Otherwise the whole buffer will be
167one big fold.
168
169The 'diffopt' option can be used to specify the context. That is, the number
170of lines between the fold and a change that are not included in the fold. For
171example, to use a context of 8 lines: >
172 :set diffopt=filler,context:8
173The default context is six lines.
174
175When 'scrollbind' is also set, Vim will attempt to keep the same folds open in
176other diff windows, so that the same text is visible.
177
178
179MARKER *fold-marker*
180
181Markers in the text tell where folds start and end. This allows you to
182precisely specify the folds. This will allow deleting and putting a fold,
183without the risk of including the wrong lines. The 'foldtext' option is
184normally set such that the text before the marker shows up in the folded line.
185This makes it possible to give a name to the fold.
186
187Markers can have a level included, or can use matching pairs. Including a
188level is easier, you don't have to add end markers and avoid problems with
189non-matching marker pairs. Example: >
190 /* global variables {{{1 */
191 int varA, varB;
192
193 /* functions {{{1 */
194 /* funcA() {{{2 */
195 void funcA() {}
196
197 /* funcB() {{{2 */
198 void funcB() {}
199
200A fold starts at a "{{{" marker. The following number specifies the fold
201level. What happens depends on the difference between the current fold level
202and the level given by the marker:
2031. If a marker with the same fold level is encountered, the previous fold
204 ends and another fold with the same level starts.
2052. If a marker with a higher fold level is found, a nested fold is started.
2063. if a marker with a lower fold level is found, all folds up to and including
207 this level end and a fold with the specified level starts.
208
Bram Moolenaar009b2592004-10-24 19:18:58 +0000209The number indicates the fold level. A zero cannot be used (a marker with
210level zero is ignored). You can use "}}}" with a digit to indicate the level
211of the fold that ends. The fold level of the following line will be one less
212than the indicated level. Note that Vim doesn't look back to the level of the
213matching marker (that would take too much time). Example: >
Bram Moolenaar071d4272004-06-13 20:20:40 +0000214
215 {{{1
216 fold level here is 1
217 {{{3
218 fold level here is 3
219 }}}3
220 fold level here is 2
221
222You can also use matching pairs of "{{{" and "}}}" markers to define folds.
223Each "{{{" increases the fold level by one, each "}}}" decreases the fold
224level by one. Be careful to keep the markers matching! Example: >
225
226 {{{
227 fold level here is 1
228 {{{
229 fold level here is 2
230 }}}
231 fold level here is 1
232
233You can mix using markers with a number and without a number. A useful way of
234doing this is to use numbered markers for large folds, and unnumbered markers
235locally in a function. For example use level one folds for the sections of
236your file like "structure definitions", "local variables" and "functions".
237Use level 2 markers for each definition and function, Use unnumbered markers
238inside functions. When you make changes in a function to split up folds, you
239don't have to renumber the markers.
240
241The markers can be set with the 'foldmarker' option. It is recommended to
242keep this at the default value of "{{{,}}}", so that files can be exchanged
243between Vim users. Only change it when it is required for the file (e.g., it
244contains markers from another folding editor, or the default markers cause
245trouble for the language of the file).
246
247 *fold-create-marker*
248"zf" can be used to create a fold defined by markers. Vim will insert the
249markers for you. Vim will append the start and end marker, as specified with
250'foldmarker'. The markers are appended to the end of the line.
251'commentstring' is used if it isn't empty.
252This does not work properly when:
253- The line already contains a marker with a level number. Vim then doesn't
254 know what to do.
255- Folds nearby use a level number in their marker which gets in the way.
256- The line is inside a comment, 'commentstring' isn't empty and nested
257 comments don't work. For example with C: adding /* {{{ */ inside a comment
258 will truncate the existing comment. Either put the marker before or after
259 the comment, or add the marker manually.
260Generally it's not a good idea to let Vim create markers when you already have
261markers with a level number.
262
263 *fold-delete-marker*
264"zd" can be used to delete a fold defined by markers. Vim will delete the
265markers for you. Vim will search for the start and end markers, as specified
266with 'foldmarker', at the start and end of the fold. When the text around the
267marker matches with 'commentstring', that text is deleted as well.
268This does not work properly when:
269- A line contains more than one marker and one of them specifies a level.
270 Only the first one is removed, without checking if this will have the
271 desired effect of deleting the fold.
272- The marker contains a level number and is used to start or end several folds
273 at the same time.
274
275==============================================================================
2762. Fold commands *fold-commands* *E490*
277
278All folding commands start with "z". Hint: the "z" looks like a folded piece
279of paper, if you look at it from the side.
280
281
282CREATING AND DELETING FOLDS ~
283 *zf* *E350*
284zf{motion} or
285{Visual}zf Operator to create a fold.
286 This only works when 'foldmethod' is "manual" or "marker".
287 The new fold will be closed for the "manual" method.
288 'foldenable' will be set.
289 Also see |fold-create-marker|.
290
291 *zF*
Bram Moolenaar5e3dae82010-03-02 16:19:40 +0100292zF Create a fold for [count] lines. Works like "zf".
Bram Moolenaar071d4272004-06-13 20:20:40 +0000293
294:{range}fo[ld] *:fold* *:fo*
295 Create a fold for the lines in {range}. Works like "zf".
296
297 *zd* *E351*
Bram Moolenaar81695252004-12-29 20:58:21 +0000298zd Delete one fold at the cursor. When the cursor is on a folded
Bram Moolenaar071d4272004-06-13 20:20:40 +0000299 line, that fold is deleted. Nested folds are moved one level
Bram Moolenaardfb18412013-12-11 18:53:29 +0100300 up. In Visual mode one level of all folds (partially) in the
301 selected area are deleted.
302 Careful: This easily deletes more folds than you expect and
303 there is no undo for manual folding.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000304 This only works when 'foldmethod' is "manual" or "marker".
305 Also see |fold-delete-marker|.
306
307 *zD*
308zD Delete folds recursively at the cursor. In Visual mode all
309 folds (partially) in the selected area and all nested folds in
310 them are deleted.
311 This only works when 'foldmethod' is "manual" or "marker".
312 Also see |fold-delete-marker|.
313
314 *zE* *E352*
315zE Eliminate all folds in the window.
316 This only works when 'foldmethod' is "manual" or "marker".
317 Also see |fold-delete-marker|.
318
319
320OPENING AND CLOSING FOLDS ~
321
322A fold smaller than 'foldminlines' will always be displayed like it was open.
323Therefore the commands below may work differently on small folds.
324
325 *zo*
326zo Open one fold under the cursor. When a count is given, that
327 many folds deep will be opened. In Visual mode one level of
328 folds is opened for all lines in the selected area.
329
330 *zO*
331zO Open all folds under the cursor recursively. Folds that don't
332 contain the cursor line are unchanged.
333 In Visual mode it opens all folds that are in the selected
334 area, also those that are only partly selected.
335
336 *zc*
337zc Close one fold under the cursor. When a count is given, that
338 many folds deep are closed. In Visual mode one level of folds
339 is closed for all lines in the selected area.
340 'foldenable' will be set.
341
342 *zC*
343zC Close all folds under the cursor recursively. Folds that
344 don't contain the cursor line are unchanged.
345 In Visual mode it closes all folds that are in the selected
346 area, also those that are only partly selected.
347 'foldenable' will be set.
348
349 *za*
Bram Moolenaar402d2fe2005-04-15 21:00:38 +0000350za When on a closed fold: open it. When folds are nested, you
Bram Moolenaar071d4272004-06-13 20:20:40 +0000351 may have to use "za" several times. When a count is given,
352 that many closed folds are opened.
353 When on an open fold: close it and set 'foldenable'. This
354 will only close one level, since using "za" again will open
355 the fold. When a count is given that many folds will be
356 closed (that's not the same as repeating "za" that many
357 times).
358
359 *zA*
360zA When on a closed fold: open it recursively.
361 When on an open fold: close it recursively and set
362 'foldenable'.
363
364 *zv*
365zv View cursor line: Open just enough folds to make the line in
366 which the cursor is located not folded.
367
368 *zx*
369zx Update folds: Undo manually opened and closed folds: re-apply
370 'foldlevel', then do "zv": View cursor line.
Bram Moolenaar00a927d2010-05-14 23:24:24 +0200371 Also forces recomputing folds. This is useful when using
372 'foldexpr' and the buffer is changed in a way that results in
373 folds not to be updated properly.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000374
375 *zX*
376zX Undo manually opened and closed folds: re-apply 'foldlevel'.
Bram Moolenaar00a927d2010-05-14 23:24:24 +0200377 Also forces recomputing folds, like |zx|.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000378
379 *zm*
Bram Moolenaar7d2757a2015-03-31 17:46:22 +0200380zm Fold more: Subtract |v:count1| from 'foldlevel'. If 'foldlevel' was
Bram Moolenaar071d4272004-06-13 20:20:40 +0000381 already zero nothing happens.
382 'foldenable' will be set.
383
384 *zM*
385zM Close all folds: set 'foldlevel' to 0.
386 'foldenable' will be set.
387
388 *zr*
Bram Moolenaar7d2757a2015-03-31 17:46:22 +0200389zr Reduce folding: Add |v:count1| to 'foldlevel'.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000390
391 *zR*
392zR Open all folds. This sets 'foldlevel' to highest fold level.
393
394 *:foldo* *:foldopen*
395:{range}foldo[pen][!]
396 Open folds in {range}. When [!] is added all folds are
397 opened. Useful to see all the text in {range}. Without [!]
398 one level of folds is opened.
399
400 *:foldc* *:foldclose*
401:{range}foldc[lose][!]
402 Close folds in {range}. When [!] is added all folds are
403 closed. Useful to hide all the text in {range}. Without [!]
404 one level of folds is closed.
405
406 *zn*
407zn Fold none: reset 'foldenable'. All folds will be open.
408
409 *zN*
410zN Fold normal: set 'foldenable'. All folds will be as they
411 were before.
412
413 *zi*
414zi Invert 'foldenable'.
415
416
417MOVING OVER FOLDS ~
418 *[z*
419[z Move to the start of the current open fold. If already at the
420 start, move to the start of the fold that contains it. If
421 there is no containing fold, the command fails.
Bram Moolenaar5e3dae82010-03-02 16:19:40 +0100422 When a count is used, repeats the command [count] times.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000423
424 *]z*
425]z Move to the end of the current open fold. If already at the
426 end, move to the end of the fold that contains it. If there
427 is no containing fold, the command fails.
Bram Moolenaar5e3dae82010-03-02 16:19:40 +0100428 When a count is used, repeats the command [count] times.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000429
430 *zj*
431zj Move downwards to the start of the next fold. A closed fold
432 is counted as one fold.
Bram Moolenaar5e3dae82010-03-02 16:19:40 +0100433 When a count is used, repeats the command [count] times.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000434 This command can be used after an |operator|.
435
436 *zk*
437zk Move upwards to the end of the previous fold. A closed fold
438 is counted as one fold.
Bram Moolenaar5e3dae82010-03-02 16:19:40 +0100439 When a count is used, repeats the command [count] times.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000440 This command can be used after an |operator|.
441
442
443EXECUTING COMMANDS ON FOLDS ~
444
445:[range]foldd[oopen] {cmd} *:foldd* *:folddoopen*
446 Execute {cmd} on all lines that are not in a closed fold.
447 When [range] is given, only these lines are used.
448 Each time {cmd} is executed the cursor is positioned on the
449 line it is executed for.
450 This works like the ":global" command: First all lines that
451 are not in a closed fold are marked. Then the {cmd} is
452 executed for all marked lines. Thus when {cmd} changes the
453 folds, this has no influence on where it is executed (except
454 when lines are deleted, of course).
455 Example: >
456 :folddoopen s/end/loop_end/ge
457< Note the use of the "e" flag to avoid getting an error message
458 where "end" doesn't match.
459
460:[range]folddoc[losed] {cmd} *:folddoc* *:folddoclosed*
461 Execute {cmd} on all lines that are in a closed fold.
462 Otherwise like ":folddoopen".

4653. Fold options *fold-options*
466
467COLORS *fold-colors*
468
469The colors of a closed fold are set with the Folded group |hl-Folded|. The
470colors of the fold column are set with the FoldColumn group |hl-FoldColumn|.
471Example to set the colors: >
472
473 :highlight Folded guibg=grey guifg=blue
474 :highlight FoldColumn guibg=darkgrey guifg=white
475
476
477FOLDLEVEL *fold-foldlevel*
478
479'foldlevel' is a number option: The higher the more folded regions are open.
480When 'foldlevel' is 0, all folds are closed.
Bram Moolenaar81695252004-12-29 20:58:21 +0000481When 'foldlevel' is positive, some folds are closed.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000482When 'foldlevel' is very high, all folds are open.
483'foldlevel' is applied when it is changed. After that manually folds can be
484opened and closed.
485When increased, folds above the new level are opened. No manually opened
486folds will be closed.
487When decreased, folds above the new level are closed. No manually closed
488folds will be opened.
489
490
491FOLDTEXT *fold-foldtext*
492
493'foldtext' is a string option that specifies an expression. This expression
494is evaluated to obtain the text displayed for a closed fold. Example: >
495
496 :set foldtext=v:folddashes.substitute(getline(v:foldstart),'/\\*\\\|\\*/\\\|{{{\\d\\=','','g')
497
498This shows the first line of the fold, with "/*", "*/" and "{{{" removed.
499Note the use of backslashes to avoid some characters to be interpreted by the
500":set" command. It's simpler to define a function and call that: >
501
502 :set foldtext=MyFoldText()
503 :function MyFoldText()
504 : let line = getline(v:foldstart)
505 : let sub = substitute(line, '/\*\|\*/\|{{{\d\=', '', 'g')
506 : return v:folddashes . sub
507 :endfunction
508
509Evaluating 'foldtext' is done in the |sandbox|. The current window is set to
510the window that displays the line. Errors are ignored.
511
512The default value is |foldtext()|. This returns a reasonable text for most
513types of folding. If you don't like it, you can specify your own 'foldtext'
514expression. It can use these special Vim variables:
515 v:foldstart line number of first line in the fold
516 v:foldend line number of last line in the fold
517 v:folddashes a string that contains dashes to represent the
518 foldlevel.
519 v:foldlevel the foldlevel of the fold
520
521In the result a TAB is replaced with a space and unprintable characters are
522made into printable characters.
523
524The resulting line is truncated to fit in the window, it never wraps.
525When there is room after the text, it is filled with the character specified
526by 'fillchars'.
527
528Note that backslashes need to be used for characters that the ":set" command
529handles differently: Space, backslash and double-quote. |option-backslash|

531
532FOLDCOLUMN *fold-foldcolumn*
533
534'foldcolumn' is a number, which sets the width for a column on the side of the
535window to indicate folds. When it is zero, there is no foldcolumn. A normal
Bram Moolenaar578b49e2005-09-10 19:22:57 +0000536value is 4 or 5. The minimal useful value is 2, although 1 still provides
537some information. The maximum is 12.
Bram Moolenaar071d4272004-06-13 20:20:40 +0000538
539An open fold is indicated with a column that has a '-' at the top and '|'
540characters below it. This column stops where the open fold stops. When folds
541nest, the nested fold is one character right of the fold it's contained in.
542
543A closed fold is indicated with a '+'.
544
545Where the fold column is too narrow to display all nested folds, digits are
546shown to indicate the nesting level.
547
548The mouse can also be used to open and close folds by clicking in the
549fold column:
550- Click on a '+' to open the closed fold at this row.
551- Click on any other non-blank character to close the open fold at this row.
552
553

567==============================================================================
5684. Behavior of folds *fold-behavior*
569
570When moving the cursor upwards or downwards and when scrolling, the cursor
571will move to the first line of a sequence of folded lines. When the cursor is
572already on a folded line, it moves to the next unfolded line or the next
573closed fold.
574
575While the cursor is on folded lines, the cursor is always displayed in the
576first column. The ruler does show the actual cursor position, but since the
577line is folded, it cannot be displayed there.
578
579Many movement commands handle a sequence of folded lines like an empty line.
580For example, the "w" command stops once in the first column.
581
582When in Insert mode, the cursor line is never folded. That allows you to see
583what you type!
584
585When using an operator, a closed fold is included as a whole. Thus "dl"
586deletes the whole closed fold under the cursor.
587
588For Ex commands the range is adjusted to always start at the first line of a
Bram Moolenaared203462004-06-16 11:19:22 +0000589closed fold and end at the last line of a closed fold. Thus this command: >
Bram Moolenaar071d4272004-06-13 20:20:40 +0000590 :s/foo/bar/g
591when used with the cursor on a closed fold, will replace "foo" with "bar" in
592all lines of the fold.
593This does not happen for |:folddoopen| and |:folddoclosed|.
594
595When editing a buffer that has been edited before, the last used folding
596settings are used again. For manual folding the defined folds are restored.
597For all folding methods the manually opened and closed folds are restored.
598If this buffer has been edited in this window, the values from back then are
599used. Otherwise the values from the window where the buffer was edited last
600are used.
