List comprehension is highlighted as error!

[ngphuoc]

The closing square bracket is highlighted as error in [i for i in 1:10]

I can not reproduce this, so I'll need more details. Does it happen under all circumstances, or do you have a specific example? Does the error persist if you refresh the file with CTRL-L? And if you reload it?

Sorry, I the error happens when I use the luochen1990\rainbow vim plugin. I have to config start and end brackets for all predefined block: juliaModuleBlock, juliaFunctionBlock, juliaRepeatBlock, juliaConditionalBlock. The juliaRepeatBlock makes this [i for i in 1:10 end] correct, but I don't know what is the name of this juliaListComprehensionBlock? block[i for i in 1:10]

below is my .vimrc

call plug#begin('~/.vim/plugged')
Plug 'JuliaEditorSupport/julia-vim'
Plug 'luochen1990/rainbow'
call plug#end()

syntax enable
filetype plugin indent on

let g:rainbow_active = 1

let g:rainbow_conf = {
    \   'guifgs': ['royalblue3', 'darkorange3', 'seagreen3', 'firebrick'],
    \   'ctermfgs': ['darkgreen', 'darkblue', 'darkgray', 'brown', 'darkcyan', 'darkred', 'darkmagenta', 'gray', 'black', 'red'],
    \   'operators': '_,_',
    \   'parentheses': ['start=/(/ end=/)/ fold', 'start=/\[/ end=/\]/ fold', 'start=/{/ end=/}/ fold'],
    \   'separately': {
    \       '*': {},
    \       'julia': {
    \           'parentheses': ['start=/(/ end=/)/', 'start=/\[/ end=/\]/', 'start=/{/ end=/}/', 'start=/(/ end=/)/ containedin=juliaConditionalBlock', 'start=/\[/ end=/\]/ containedin=juliaConditionalBlock', 'start=/{/ end=/}/ containedin=juliaConditionalBlock', 'start=/(/ end=/)/ containedin=juliaModuleBlock', 'start=/\[/ end=/\]/ containedin=juliaModuleBlock', 'start=/{/ end=/}/ containedin=juliaModuleBlock', 'start=/(/ end=/)/ containedin=juliaFunctionBlock', 'start=/\[/ end=/\]/ containedin=juliaFunctionBlock', 'start=/{/ end=/}/ containedin=juliaFunctionBlock', 'start=/(/ end=/)/ containedin=juliaRepeatBlock', 'start=/\[/ end=/\]/ containedin=juliaRepeatBlock', 'start=/{/ end=/}/ containedin=juliaRepeatBlock', 'start=/(/ end=/)/ containedin=juliaModuleBlock', 'start=/\[/ end=/\]/ containedin=juliaModuleBlock', 'start=/{/ end=/}/ containedin=juliaModuleBlock'],
    \       },
    \       'vim': {
    \           'parentheses': ['start=/(/ end=/)/', 'start=/\[/ end=/\]/', 'start=/{/ end=/}/ fold', 'start=/(/ end=/)/ containedin=vimFuncBody', 'start=/\[/ end=/\]/ containedin=vimFuncBody', 'start=/{/ end=/}/ fold containedin=vimFuncBody'],
    \       },
    \

Could you advise some hint? Many thanks.

I have the same error using junegunn/rainbow_parentheses.vim

I've also checked that python list comprehension is OK for both rainbow plugins

I have investigated the issue. The problem is that rainbow supersedes the syntax file definitions of the parentheses. As a quick fix for the issue at hand, you can just add contains=juliaComprehensionFor,juliaComprehensionIf for all () and [] parentheses definitions.

However, you should be aware that 1) there are more block types than the ones you have defined (see here); 2) the syntax file uses contained, contains and containedin directives to (more or less) faithfully reproduce julia's own parsing rules, which are quite complex, and messing with that (as rainbow does) will very likely lead to other (more subtle) issues. For example, in some contexts the end keyword is recognized as an indexing expression (see e.g. this). Basically, you'd need to look into the julia syntax file and reproduce what's done there. And coordinate with that in case of changes.

My advice is to just disable rainbow for julia files...

Thank you for your solution! I have been able to config it to recognize 1 level list comprehension. I still get an error for list of list comprehension, but 1 level is enough for me currently.

@ngphuoc Apologies for reviving this long-dead issue, but do you mind sharing the snippet of your config that helped you resolve the problem for 1 level of list comprehensions? I hope you still have a copy of it.

I also apologize for reviving this another 2 years later. I would love a solution for this as I am hitting the exact same issue with rainbow and julia-vim.
