vim-patch:8.1.1726: the eval.txt help file is too big

Browse Source 
Problem:    The eval.txt help file is too big.
Solution:   Split off testing support to testing.txt.  Move function details
            to where the functionality is explained.

@ -2641,122 +2641,7 @@ argv([{nr} [, {winid}])
The {winid} argument specifies the window ID, see |argc()|.
For the Vim command line arguments see |v:argv|.
assert_beeps({cmd}) *assert_beeps()*
Run {cmd} and add an error message to |v:errors| if it does
NOT produce a beep or visual bell.
Also see |assert_fails()|, |assert_nobeep()| and
|assert-return|.
*assert_equal()*
assert_equal({expected}, {actual}, [, {msg}])
When {expected} and {actual} are not equal an error message is
added to |v:errors| and 1 is returned. Otherwise zero is
returned |assert-return|.
There is no automatic conversion, the String "4" is different
from the Number 4. And the number 4 is different from the
Float 4.0. The value of 'ignorecase' is not used here, case
always matters.
When {msg} is omitted an error in the form "Expected
{expected} but got {actual}" is produced.
Example: >
assert_equal('foo', 'bar')
< Will result in a string to be added to |v:errors|:
test.vim line 12: Expected 'foo' but got 'bar' ~
*assert_equalfile()*
assert_equalfile({fname-one}, {fname-two} [, {msg}])
When the files {fname-one} and {fname-two} do not contain
exactly the same text an error message is added to |v:errors|.
Also see |assert-return|.
When {fname-one} or {fname-two} does not exist the error will
mention that.
assert_exception({error} [, {msg}]) *assert_exception()*
When v:exception does not contain the string {error} an error
message is added to |v:errors|. Also see |assert-return|.
This can be used to assert that a command throws an exception.
Using the error number, followed by a colon, avoids problems
with translations: >
try
commandthatfails
call assert_false(1, 'command should have failed')
catch
call assert_exception('E492:')
endtry
assert_fails({cmd} [, {error} [, {msg}]]) *assert_fails()*
Run {cmd} and add an error message to |v:errors| if it does
NOT produce an error. Also see |assert-return|.
When {error} is given it must match in |v:errmsg|.
Note that beeping is not considered an error, and some failing
commands only beep. Use |assert_beeps()| for those.
assert_false({actual} [, {msg}]) *assert_false()*
When {actual} is not false an error message is added to
|v:errors|, like with |assert_equal()|.
Also see |assert-return|.
A value is false when it is zero or |v:false|. When "{actual}"
is not a number or |v:false| the assert fails.
When {msg} is omitted an error in the form
"Expected False but got {actual}" is produced.
assert_inrange({lower}, {upper}, {actual} [, {msg}]) *assert_inrange()*
This asserts number and |Float| values. When {actual} is lower
than {lower} or higher than {upper} an error message is added
to |v:errors|. Also see |assert-return|.
When {msg} is omitted an error in the form
"Expected range {lower} - {upper}, but got {actual}" is
produced.
*assert_match()*
assert_match({pattern}, {actual} [, {msg}])
When {pattern} does not match {actual} an error message is
added to |v:errors|. Also see |assert-return|.
{pattern} is used as with |=~|: The matching is always done
like 'magic' was set and 'cpoptions' is empty, no matter what
the actual value of 'magic' or 'cpoptions' is.
{actual} is used as a string, automatic conversion applies.
Use "^" and "$" to match with the start and end of the text.
Use both to match the whole text.
When {msg} is omitted an error in the form
"Pattern {pattern} does not match {actual}" is produced.
Example: >
assert_match('^f.*o$', 'foobar')
< Will result in a string to be added to |v:errors|:
test.vim line 12: Pattern '^f.*o$' does not match 'foobar' ~
assert_nobeep({cmd}) *assert_nobeep()*
Run {cmd} and add an error message to |v:errors| if it
produces a beep or visual bell.
Also see |assert_beeps()|.
*assert_notequal()*
assert_notequal({expected}, {actual} [, {msg}])
The opposite of `assert_equal()`: add an error message to
|v:errors| when {expected} and {actual} are equal.
Also see |assert-return|.
*assert_notmatch()*
assert_notmatch({pattern}, {actual} [, {msg}])
The opposite of `assert_match()`: add an error message to
|v:errors| when {pattern} matches {actual}.
Also see |assert-return|.
assert_report({msg}) *assert_report()*
Report a test failure directly, using {msg}.
Always returns one.
assert_true({actual} [, {msg}]) *assert_true()*
When {actual} is not true an error message is added to
|v:errors|, like with |assert_equal()|.
Also see |assert-return|.
A value is |TRUE| when it is a non-zero number or |v:true|.
When {actual} is not a number or |v:true| the assert fails.
When {msg} is omitted an error in the form "Expected True but
got {actual}" is produced.
assert_ functions are documented here: |assert-functions-details|

'vartabstop' feature. If no {col} argument is given, column 1
will be assumed.
sign_define({name} [, {dict}]) *sign_define()*
sign_define({list})
Define a new sign named {name} or modify the attributes of an
existing sign. This is similar to the |:sign-define| command.
sign_ functions are documented here: |sign-functions-details|
Prefix {name} with a unique text to avoid name collisions.
There is no {group} like with placing signs.
The {name} can be a String or a Number. The optional {dict}
argument specifies the sign attributes. The following values
are supported:
icon full path to the bitmap file for the sign.
linehl highlight group used for the whole line the
sign is placed in.
text text that is displayed when there is no icon
or the GUI is not being used.
texthl highlight group used for the text item
numhl highlight group used for 'number' column at the
associated line. Overrides |hl-LineNr|,
|hl-CursorLineNr|.
If the sign named {name} already exists, then the attributes
of the sign are updated.
The one argument {list} can be used to define a list of signs.
Each list item is a dictionary with the above items in {dict}
and a 'name' item for the sign name.
Returns 0 on success and -1 on failure. When the one argument
{list} is used, then returns a List of values one for each
defined sign.
Examples: >
call sign_define("mySign", {
\ "text" : "=>",
\ "texthl" : "Error",
\ "linehl" : "Search"})
call sign_define([
\ {'name' : 'sign1',
\ 'text' : '=>'},
\ {'name' : 'sign2',

<
sign_getdefined([{name}]) *sign_getdefined()*
Get a list of defined signs and their attributes.
This is similar to the |:sign-list| command.
If the {name} is not supplied, then a list of all the defined
signs is returned. Otherwise the attribute of the specified
sign is returned.
Each list item in the returned value is a dictionary with the
following entries:
icon full path to the bitmap file of the sign
linehl highlight group used for the whole line the
sign is placed in.
name name of the sign
text text that is displayed when there is no icon
or the GUI is not being used.
texthl highlight group used for the text item
numhl highlight group used for 'number' column at the
associated line. Overrides |hl-LineNr|,
|hl-CursorLineNr|.
Returns an empty List if there are no signs and when {name} is
not found.
Examples: >
" Get a list of all the defined signs
echo sign_getdefined()
" Get the attribute of the sign named mySign
echo sign_getdefined("mySign")
<
sign_getplaced([{expr} [, {dict}]]) *sign_getplaced()*
Return a list of signs placed in a buffer or all the buffers.
This is similar to the |:sign-place-list| command.
If the optional buffer name {expr} is specified, then only the
list of signs placed in that buffer is returned. For the use
of {expr}, see |bufname()|. The optional {dict} can contain
the following entries:
group select only signs in this group
id select sign with this identifier
lnum select signs placed in this line. For the use
of {lnum}, see |line()|.
If {group} is '*', then signs in all the groups including the
global group are returned. If {group} is not supplied or is an
empty string, then only signs in the global group are
returned. If no arguments are supplied, then signs in the
global group placed in all the buffers are returned.
See |sign-group|.
Each list item in the returned value is a dictionary with the
following entries:
bufnr number of the buffer with the sign
signs list of signs placed in {bufnr}. Each list
item is a dictionary with the below listed
entries
The dictionary for each sign contains the following entries:
group sign group. Set to '' for the global group.
id identifier of the sign
lnum line number where the sign is placed
name name of the defined sign
priority sign priority
The returned signs in a buffer are ordered by their line
number and priority.
Returns an empty list on failure or if there are no placed
signs.
Examples: >
" Get a List of signs placed in eval.c in the
" global group
echo sign_getplaced("eval.c")

*sign_jump()*
sign_jump({id}, {group}, {expr})
Open the buffer {expr} or jump to the window that contains
{expr} and position the cursor at sign {id} in group {group}.
This is similar to the |:sign-jump| command.
For the use of {expr}, see |bufname()|.
Returns the line number of the sign. Returns -1 if the
arguments are invalid.
Example: >
" Jump to sign 10 in the current buffer
call sign_jump(10, '', '')
<
*sign_place()*
sign_place({id}, {group}, {name}, {expr} [, {dict}])
Place the sign defined as {name} at line {lnum} in file or
buffer {expr} and assign {id} and {group} to sign. This is
similar to the |:sign-place| command.
If the sign identifier {id} is zero, then a new identifier is
allocated. Otherwise the specified number is used. {group} is
the sign group name. To use the global sign group, use an
empty string. {group} functions as a namespace for {id}, thus
two groups can use the same IDs. Refer to |sign-identifier|
and |sign-group| for more information.
{name} refers to a defined sign.
{expr} refers to a buffer name or number. For the accepted
values, see |bufname()|.
The optional {dict} argument supports the following entries:
lnum line number in the file or buffer
{expr} where the sign is to be placed.
For the accepted values, see |line()|.
priority priority of the sign. See
|sign-priority| for more information.
If the optional {dict} is not specified, then it modifies the
placed sign {id} in group {group} to use the defined sign
{name}.
Returns the sign identifier on success and -1 on failure.
Examples: >
" Place a sign named sign1 with id 5 at line 20 in
" buffer json.c

" Place a sign named sign4 with id 10 in group 'g3'
" at line 40 in buffer json.c with priority 90
call sign_place(10, 'g3', 'sign4', 'json.c',
\ {'lnum' : 40, 'priority' : 90})
<
*sign_placelist()*
sign_placelist({list})
Place one or more signs. This is similar to the
|sign_place()| function. The {list} argument specifies the
List of signs to place. Each list item is a dict with the
following sign attributes:
buffer buffer name or number. For the accepted
values, see |bufname()|.
group sign group. {group} functions as a namespace
for {id}, thus two groups can use the same
IDs. If not specified or set to an empty
string, then the global group is used. See
|sign-group| for more information.
id sign identifier. If not specified or zero,
then a new unique identifier is allocated.
Otherwise the specified number is used. See
|sign-identifier| for more information.
lnum line number in the buffer {expr} where the
sign is to be placed. For the accepted values,
see |line()|.
name name of the sign to place. See |sign_define()|
for more information.
priority priority of the sign. When multiple signs are
placed on a line, the sign with the highest
priority is used. If not specified, the
default value of 10 is used. See
|sign-priority| for more information.
If {id} refers to an existing sign, then the existing sign is
modified to use the specified {name} and/or {priority}.
Returns a List of sign identifiers. If failed to place a
sign, the corresponding list item is set to -1.
Examples: >
" Place sign s1 with id 5 at line 20 and id 10 at line
" 30 in buffer a.c
let [n1, n2] = sign_place([
\ {'id' : 5,
\ 'name' : 's1',

sign_undefine([{name}]) *sign_undefine()*
sign_undefine({list})
Deletes a previously defined sign {name}. This is similar to
the |:sign-undefine| command. If {name} is not supplied, then
deletes all the defined signs.
The one argument {list} can be used to undefine a list of
signs. Each list item is the name of a sign.
Returns 0 on success and -1 on failure. For the one argument
{list} call, returns a list of values one for each undefined
sign.
Examples: >
" Delete a sign named mySign
call sign_undefine("mySign")
" Delete signs 'sign1' and 'sign2'
call sign_undefine(["sign1", "sign2"])
" Delete all the signs
call sign_undefine()
<
sign_unplace({group} [, {dict}]) *sign_unplace()*
Remove a previously placed sign in one or more buffers. This
is similar to the |:sign-unplace| command.
{group} is the sign group name. To use the global sign group,
use an empty string. If {group} is set to '*', then all the
groups including the global group are used.
The signs in {group} are selected based on the entries in
{dict}. The following optional entries in {dict} are
supported:
buffer buffer name or number. See |bufname()|.
id sign identifier
If {dict} is not supplied, then all the signs in {group} are
removed.
Returns 0 on success and -1 on failure.
Examples: >

call sign_unplace('*')
<
sign_unplacelist({list}) *sign_unplacelist()*
Remove previously placed signs from one or more buffers. This
is similar to the |sign_unplace()| function.
The {list} argument specifies the List of signs to remove.
Each list item is a dict with the following sign attributes:
buffer buffer name or number. For the accepted
values, see |bufname()|. If not specified,
then the specified sign is removed from all
the buffers.
group sign group name. If not specified or set to an
empty string, then the global sign group is
used. If set to '*', then all the groups
including the global group are used.
id sign identifier. If not specified, then all
the signs in the specified group are removed.
Returns a List where an entry is set to 0 if the corresponding
sign was successfully removed or -1 on failure.

sign is to be placed. For the accepted values,
see |line()|.
name name of the sign to place. See |sign_define()|
for more information.
priority priority of the sign. When multiple signs are
placed on a line, the sign with the highest
priority is used. If not specified, the
default value of 10 is used. See
|sign-priority| for more information.
If {id} refers to an existing sign, then the existing sign is
modified to use the specified {name} and/or {priority}.
Returns a List of sign identifiers. If failed to place a
sign, the corresponding list item is set to -1.
Examples: >
" Place sign s1 with id 5 at line 20 and id 10 at line
" 30 in buffer a.c
let [n1, n2] = sign_placelist([
\ {'id' : 5,
\ 'name' : 's1',
\ 'buffer' : 'a.c',
\ 'lnum' : 20},
\ {'id' : 10,
\ 'name' : 's1',
\ 'buffer' : 'a.c',
\ 'lnum' : 30}
\ ])
" Place sign s1 in buffer a.c at line 40 and 50
" with auto-generated identifiers
let [n1, n2] = sign_placelist([
\ {'name' : 's1',
\ 'buffer' : 'a.c',
\ 'lnum' : 40},
\ {'name' : 's1',
\ 'buffer' : 'a.c',
\ 'lnum' : 50}
\ ])
<
sign_undefine([{name}]) *sign_undefine()*
sign_undefine({list})
Deletes a previously defined sign {name}. This is similar to
the |:sign-undefine| command. If {name} is not supplied, then
deletes all the defined signs.
The one argument {list} can be used to undefine a list of
signs. Each list item is the name of a sign.
Returns 0 on success and -1 on failure. For the one argument
{list} call, returns a list of values one for each undefined
sign.
Examples: >
" Delete a sign named mySign
call sign_undefine("mySign")
" Delete signs 'sign1' and 'sign2'
call sign_undefine(["sign1", "sign2"])
" Delete all the signs
call sign_undefine()
<
sign_unplace({group} [, {dict}]) *sign_unplace()*
Remove a previously placed sign in one or more buffers. This
is similar to the |:sign-unplace| command.
{group} is the sign group name. To use the global sign group,
use an empty string. If {group} is set to '*', then all the
groups including the global group are used.
The signs in {group} are selected based on the entries in
{dict}. The following optional entries in {dict} are
supported:
buffer buffer name or number. See |bufname()|.
id sign identifier
If {dict} is not supplied, then all the signs in {group} are
removed.
Returns 0 on success and -1 on failure.
Examples: >
" Remove sign 10 from buffer a.vim
call sign_unplace('', {'buffer' : "a.vim", 'id' : 10})
" Remove sign 20 in group 'g1' from buffer 3
call sign_unplace('g1', {'buffer' : 3, 'id' : 20})
" Remove all the signs in group 'g2' from buffer 10
call sign_unplace('g2', {'buffer' : 10})
" Remove sign 30 in group 'g3' from all the buffers
call sign_unplace('g3', {'id' : 30})
" Remove all the signs placed in buffer 5
call sign_unplace('*', {'buffer' : 5})
" Remove the signs in group 'g4' from all the buffers
call sign_unplace('g4')
" Remove sign 40 from all the buffers
call sign_unplace('*', {'id' : 40})
" Remove all the placed signs from all the buffers
call sign_unplace('*')
<
sign_unplacelist({list}) *sign_unplacelist()*
Remove previously placed signs from one or more buffers. This
is similar to the |sign_unplace()| function.
The {list} argument specifies the List of signs to remove.
Each list item is a dict with the following sign attributes:
buffer buffer name or number. For the accepted
values, see |bufname()|. If not specified,
then the specified sign is removed from all
the buffers.
group sign group name. If not specified or set to an
empty string, then the global sign group is
used. If set to '*', then all the groups
including the global group are used.
id sign identifier. If not specified, then all
the signs in the specified group are removed.
Returns a List where an entry is set to 0 if the corresponding
sign was successfully removed or -1 on failure.
Example: >
" Remove sign with id 10 from buffer a.vim and sign
" with id 20 from buffer b.vim
call sign_unplacelist([
\ {'id' : 10, 'buffer' : "a.vim"},
\ {'id' : 20, 'buffer' : 'b.vim'},
\ ])

*testing.txt* Nvim
VIM REFERENCE MANUAL by Bram Moolenaar
Testing Vim and Vim script *testing-support*
Expression evaluation is explained in |eval.txt|. This file goes into details
about writing tests in Vim script. This can be used for testing Vim itself
and for testing plugins.
1. Testing Vim |testing|
2. Test functions |test-functions-details|
3. Assert funtions |assert-functions-details|
==============================================================================
1. Testing Vim *testing*
Vim can be tested after building it, usually with "make test".
The tests are located in the directory "src/testdir".
There are several types of tests added over time:
test33.in oldest, don't add any of these
test_something.in old style tests
test_something.vim new style tests
*new-style-testing*
New tests should be added as new style tests. These use functions such as
|assert_equal()| to keep the test commands and the expected result in one
place.
*old-style-testing*
In some cases an old style test needs to be used. E.g. when testing Vim
without the |+eval| feature.
Find more information in the file src/testdir/README.txt.
==============================================================================
2. Test functions *test-functions-details*
test_garbagecollect_now() *test_garbagecollect_now()*
Like garbagecollect(), but executed right away. This must
only be called directly to avoid any structure to exist
internally, and |v:testing| must have been set before calling
any function.
==============================================================================
3. Assert functions *assert-functions-details*
assert_beeps({cmd}) *assert_beeps()*
Run {cmd} and add an error message to |v:errors| if it does
NOT produce a beep or visual bell.
Also see |assert_fails()|, |assert_nobeep()| and
|assert-return|.
*assert_equal()*
assert_equal({expected}, {actual} [, {msg}])
When {expected} and {actual} are not equal an error message is
added to |v:errors| and 1 is returned. Otherwise zero is
returned |assert-return|.
There is no automatic conversion, the String "4" is different
from the Number 4. And the number 4 is different from the
Float 4.0. The value of 'ignorecase' is not used here, case
always matters.
When {msg} is omitted an error in the form "Expected
{expected} but got {actual}" is produced.
Example: >
assert_equal('foo', 'bar')
< Will result in a string to be added to |v:errors|:
test.vim line 12: Expected 'foo' but got 'bar' ~
*assert_equalfile()*
assert_equalfile({fname-one}, {fname-two})
When the files {fname-one} and {fname-two} do not contain
exactly the same text an error message is added to |v:errors|.
Also see |assert-return|.
When {fname-one} or {fname-two} does not exist the error will
mention that.
assert_exception({error} [, {msg}]) *assert_exception()*
When v:exception does not contain the string {error} an error
message is added to |v:errors|. Also see |assert-return|.
This can be used to assert that a command throws an exception.
Using the error number, followed by a colon, avoids problems
with translations: >
try
commandthatfails
call assert_false(1, 'command should have failed')
catch
call assert_exception('E492:')
endtry
assert_fails({cmd} [, {error} [, {msg}]]) *assert_fails()*
Run {cmd} and add an error message to |v:errors| if it does
NOT produce an error. Also see |assert-return|.
When {error} is given it must match in |v:errmsg|.
Note that beeping is not considered an error, and some failing
commands only beep. Use |assert_beeps()| for those.
assert_false({actual} [, {msg}]) *assert_false()*
When {actual} is not false an error message is added to
|v:errors|, like with |assert_equal()|.
Also see |assert-return|.
A value is false when it is zero. When {actual} is not a
number the assert fails.
When {msg} is omitted an error in the form
"Expected False but got {actual}" is produced.
assert_inrange({lower}, {upper}, {actual} [, {msg}]) *assert_inrange()*
This asserts number and |Float| values. When {actual} is lower
than {lower} or higher than {upper} an error message is added
to |v:errors|. Also see |assert-return|.
When {msg} is omitted an error in the form
"Expected range {lower} - {upper}, but got {actual}" is
produced.
*assert_match()*
assert_match({pattern}, {actual} [, {msg}])
When {pattern} does not match {actual} an error message is
added to |v:errors|. Also see |assert-return|.
{pattern} is used as with |=~|: The matching is always done
like 'magic' was set and 'cpoptions' is empty, no matter what
the actual value of 'magic' or 'cpoptions' is.
{actual} is used as a string, automatic conversion applies.
Use "^" and "$" to match with the start and end of the text.
Use both to match the whole text.
When {msg} is omitted an error in the form
"Pattern {pattern} does not match {actual}" is produced.
Example: >
assert_match('^f.*o$', 'foobar')
< Will result in a string to be added to |v:errors|:
test.vim line 12: Pattern '^f.*o$' does not match 'foobar' ~
assert_nobeep({cmd}) *assert_nobeep()*
Run {cmd} and add an error message to |v:errors| if it
produces a beep or visual bell.
Also see |assert_beeps()|.
*assert_notequal()*
assert_notequal({expected}, {actual} [, {msg}])
The opposite of `assert_equal()`: add an error message to
|v:errors| when {expected} and {actual} are equal.
Also see |assert-return|.
*assert_notmatch()*
assert_notmatch({pattern}, {actual} [, {msg}])
The opposite of `assert_match()`: add an error message to
|v:errors| when {pattern} matches {actual}.
Also see |assert-return|.
assert_report({msg}) *assert_report()*
Report a test failure directly, using {msg}.
Always returns one.
assert_true({actual} [, {msg}]) *assert_true()*
When {actual} is not true an error message is added to
|v:errors|, like with |assert_equal()|.
Also see |assert-return|.
A value is |TRUE| when it is a non-zero number or |v:true|.
When {actual} is not a number or |v:true| the assert fails.
When {msg} is omitted an error in the form "Expected True but
got {actual}" is produced.
