RUBY *ruby.vim* *ft-ruby-syntax*
|
||
|
|
|
||
|
|
There are a number of options to the Ruby syntax highlighting.
|
||
|
|
|
||
|
|
1. Ruby operators |ruby_operators|
|
||
|
|
2. Whitespace errors |ruby_space_errors|
|
||
|
|
3. Folds |ruby_fold|
|
||
|
|
4. Reducing expensive operations |ruby_no_expensive| |ruby_minlines|
|
||
|
|
|
||
|
|
|
||
|
|
1. Ruby operators *ruby_operators*
|
||
|
|
|
||
|
|
Ruby operators can be highlighted.
|
||
|
|
|
||
|
|
This is enabled by defining "ruby_operators": >
|
||
|
|
|
||
|
|
:let ruby_operators = 1
|
||
|
|
<
|
||
|
|
|
||
|
|
2. Whitespace errors *ruby_space_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.
|
||
|
|
|
||
|
|
3. Folds *ruby_fold*
|
||
|
|
|
||
|
|
Folds can be enabled by defining "ruby_fold": >
|
||
|
|
|
||
|
|
:let ruby_fold = 1
|
||
|
|
<
|
||
|
|
|
||
|
|
This will set the value |foldmethod| to "syntax" locally to the current buffer
|
||
|
|
or window, which will enable syntax-based folding when editing Ruby filetypes.
|
||
|
|
|
||
|
|
4. Reducing expensive operations *ruby_no_expensive*
|
||
|
|
|
||
|
|
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.
