* Improve test_color to prevent regressionTakashi Kokubun2019-06-041-2/+1
| | | | | Actually de541fe1961370e64541d73c96cf790d30f28604 was still needed. This commit would improve the test coverage using the branch.
* colorize_code must return escaped textTakashi Kokubun2019-06-041-2/+3
| | | | | This was needed before 0c459af7c233adb5f44022350bfe8fa132d8053e but it could be actually useless now. But I added this anyway just in case.
* Colorize error charactersNobuyoshi Nakada2019-06-041-8/+5
| | | | | | * lib/irb/color.rb (IRB::Color.scan): ignore "incomplete end of input" error only, to colorize invalid characters, e.g., control characters, and invalid symbols, as errors.
* Warn compile_error only when input is finishedTakashi Kokubun2019-05-311-3/+31
| | | | | | | | | | | | | | | | | | | | Let's say we are in progress to write `"foo"`: ``` irb> "fo ``` at this moment, nothing is wrong. It would be just a normal way to write `"foo"`. Prior to this commit, the `fo` part was warned because of 5b64d7ac6e7cbf759b859428f125539e58bac0bd. But I think warning such a normal input is not valuable for users. However, we'd like to warn `:@1` or `@@1` which is also a syntax error. Then this commit switches the syntax highlight based on whether the input text is finished or not. When it's not finished yet, it does not warn compile_error.
* Colorize errors moreNobuyoshi Nakada2019-05-291-0/+1
| | | | | * lib/irb/color.rb (IRB::Color.colorize_code): colorize `compile_error` part as same as `on_parse_error`.

* context.rb: hide wrapping linesNobuyoshi Nakada2019-05-271-0/+5
| | | | | | * lib/irb/context.rb (IRB::Context#evaluate): separate the code from wrapping lines to propagate the given exception, not to show the wrapping lines when SyntaxError.
* Highlight global variable on IRBTakashi Kokubun2019-05-261-0/+1
|
* Refactor IRB color dispatchTakashi Kokubun2019-05-261-1/+1
| | | | | | | | | | | | | | | The reason why we were checking lexer state in addition to token was that we do not want to colorize local variable, method call, etc., while they share the :on_ident token with a name of method definition which should be colored as blue. It means that we're concerned about the lexer state only for :on_ident. Thus we can skip checking lexer state for non-:on_ident tokens. This refactoring is based on that idea. Also, now we manage Ripper's lexer state as Integer (use `|` if you need to check multiple states). It should be faster than using Array of Integer because #any? block call is not needed.

* Fix scanner event at invalid syntaxNobuyoshi Nakada2019-05-261-1/+1
| | | | | | * parse.y (parser_yyerror, parser_compile_error): revert r67224 (e5d10cda07b23682e5e4e64d1324e4d3247d4785) "Flush erred token".

* Always color Symbol as Yellow on IRB::ColorTakashi Kokubun2019-05-251-2/+6
| | | | | | | | | | | | | | | | | | | Symbol color was made blue as a workaround because it was hard to distinguish `foo`s in `:foo` and `def foo; end` (both are :on_ident). But I wanted to make it yellow like pry. `:Struct` had the same problem in :on_const. Because the :on_const was also blue (but underlined and bold), it was not a big issue. While they're not so problematic since we got a workaround, we also had a more serious issue for highlighting a symbol like `:"a#{b}c"`. The first half was considered as Symbol and the last half was considered as String, because the colorizer did not have a state like a parser. To approach the last issue, I introduced `IRB::Color::SymbolState` which is a thin state manager knowing only "the token is Symbol or not". Having this module magically solves the first two problems as well. So now we can highlight Symbol as yellow in the perfect manner.
