|
|
Ruby: Operator highlighting ~
|
|
|
|
Operators, and pseudo operators, can be highlighted by defining: >
|
|
|
|
:let ruby_operators = 1
|
|
:let ruby_pseudo_operators = 1
|
|
<
|
|
The supported pseudo operators are ., &., ::, *, **, &, <, << and ->.
|
|
|
|
*ruby_space_errors*
|
|
Ruby: Whitespace errors ~
|
|
|
|
Whitespace errors can be highlighted by defining "ruby_space_errors": >
|
|
|
|
:let ruby_space_errors = 1
|
|
<
|
|
This will highlight trailing whitespace and tabs preceded by a space character
|
|
as errors. This can be refined by defining "ruby_no_trail_space_error" and
|
|
"ruby_no_tab_space_error" which will ignore trailing whitespace and tabs after
|
|
spaces respectively.
|
|
|
|
*ruby_syntax_errors*
|
|
Ruby: Syntax errors ~
|
|
|
|
Redundant line continuations and predefined global variable look-alikes (such
|
|
as $# and $-z) can be highlighted as errors by defining:
|
|
>
|
|
:let ruby_line_continuation_error = 1
|
|
:let ruby_global_variable_error = 1
|
|
<
|
|
*ruby_fold*
|
|
Ruby: Folding ~
|
|
|
|
Folding can be enabled by defining "ruby_fold": >
|
|
|
|
:let ruby_fold = 1
|
|
<
|
|
This will set the value of 'foldmethod' to "syntax" locally to the current
|
|
buffer or window, which will enable syntax-based folding when editing Ruby
|
|
filetypes.
|
|
|
|
*ruby_foldable_groups*
|
|
Default folding is rather detailed, i.e., small syntax units like "if", "do",
|
|
"%w[]" may create corresponding fold levels.
|
|
|
|
You can set "ruby_foldable_groups" to restrict which groups are foldable: >
|
|
|
|
:let ruby_foldable_groups = 'if case %'
|
|
<
|
|
The value is a space-separated list of keywords:
|
|
|
|
keyword meaning ~
|
|
-------- ------------------------------------- ~
|
|
ALL Most block syntax (default)
|
|
NONE Nothing
|
|
if "if" or "unless" block
|
|
def "def" block
|
|
class "class" block
|
|
module "module" block
|
|
do "do" block
|
|
begin "begin" block
|
|
case "case" block
|
|
for "for", "while", "until" loops
|
|
{ Curly bracket block or hash literal
|
|
[ Array literal
|
|
% Literal with "%" notation, e.g.: %w(STRING), %!STRING!
|
|
/ Regexp
|
|
string String and shell command output (surrounded by ', ", `)
|
|
: Symbol
|
|
# Multiline comment
|
|
<< Here documents
|
|
__END__ Source code after "__END__" directive
|
|
|
|
NONE and ALL have priority, in that order, over all other folding groups.
|
|
|
|
*ruby_no_expensive*
|
|
Ruby: Reducing expensive operations ~
|
|
|
|
By default, the "end" keyword is colorized according to the opening statement
|
|
of the block it closes. While useful, this feature can be expensive; if you
|
|
experience slow redrawing (or you are on a terminal with poor color support)
|
|
you may want to turn it off by defining the "ruby_no_expensive" variable: >
|
|
|
|
:let ruby_no_expensive = 1
|
|
<
|
|
In this case the same color will be used for all control keywords.
|
|
|
|
*ruby_minlines*
|
|
|
|
If you do want this feature enabled, but notice highlighting errors while
|
|
scrolling backwards, which are fixed when redrawing with CTRL-L, try setting
|
|
the "ruby_minlines" variable to a value larger than 50: >
|
|
|
|
:let ruby_minlines = 100
|
|
<
|
|
Ideally, this value should be a number of lines large enough to embrace your
|
|
largest class or module.
|
|
|
|
*ruby_spellcheck_strings*
|
|
Ruby: Spellchecking strings ~
|
|
|
|
Ruby syntax will perform spellchecking of strings if you define
|
|
"ruby_spellcheck_strings": >
|
|
|
|
:let ruby_spellcheck_strings = 1
|
|
<
