E254: Cannot allocate color

[edaplayer]

I had the problem after install，i use vim 8.2.1076 not neovim.

Did you set the termguicolors?

[edaplayer]

Did you set the termguicolors? 我是在securecrt上远程ssh使用vim的，是虚拟终端。 设置termguicolors之后变成黑白色了，也会报错： Error detected while processing function spaceline#spacelinetoggle[2]..66_SetStatusline[6]..66_ActiveStatusLine[1].. spaceline#syntax#icon_syntax: line 7: E254: Cannot allocate color # E254: Cannot allocate color #

[glepnir]

没法重现。最小配置.vim 8.1

set runtimepath+=~/workstation/vim/spaceline.vim
set runtimepath+=~/.cache/vim/dein/repos/github.com/ryanoasis/vim-devicons

set laststatus=2
set termguicolors
syntax on

[edaplayer]

看信息似乎是这个函数第7行出了问题，你的vim-devicons是最新版本的吗？

59 function! spaceline#syntax#icon_syntax()
 60     let icon = substitute(WebDevIconsGetFileTypeSymbol(), "\u00A0", '', '') 
 61     let bg_color = substitute(synIDattr(hlID("FileName"), "bg"),'#','','') 
 62  
 63     for color in keys(g:coldevicons_iconmap) 
 64         let index = index(g:coldevicons_iconmap[color], icon) 
 65         if index != -1 
 66           execute 'highlight! FileIcon'.color.' guifg=#'.g:coldevicons_colormap[color].' ctermfg='.s:rgb(g:coldevicons_colormap[color]) . ' guibg=#' . bg_color 

[glepnir]

那只是图标。提示不能解析颜色索引。我这边试了最小配置是没问题的。 不清楚你的环境了。

[edaplayer]

我屏蔽 execute 这行就不会报错了

[glepnir]

肯定啊 都不执行高亮文件图标颜色了哪里还有错误。问题不是出在代码上。

[edaplayer]

不管是不是代码问题，问题总要解决啊，我把颜色打印出来，bg_color是空值， 那么let bg_color = substitute(synIDattr(hlID("FileName"), "bg"),'#','','') 返回空值，这里为什么拿不到FileName语法颜色才是问题点

[glepnir]

Filename 是旁边文件名称的背景颜色。如果是space主题 拿到是紫色purple 加载了主题就肯定能拿到颜色值https://github.com/hardcoreplayers/spaceline.vim/blob/71d6dbacb9c011b74f3e1043bebee6edbbdd80c1/autoload/spaceline/colorscheme/space.vim#L87

在初始化阶段没有拿到颜色值，第三次才拿到

[glepnir]

你用最新的测吧我两天前更了一下。

[edaplayer]

已经最新的了，今天刚下的，vim也是最新的

[edaplayer]

有可能c库版本太老，我这是ubuntu12.04，下次我试试换ubuntu看看

[glepnir]

你是怎么加载的？我试了最小配置怎么都没法重现。

[glepnir]

很多人用spaceline的都没出问题这块。所以很奇怪。和依赖没关系你vim能正常运行。

[edaplayer]

最小配置我试了，一样的现象

我的vim编译配置是：

./configure --with-features=huge \
        --enable-multibyte \
        --enable-rubyinterp=yes \
        --enable-python3interp=yes \
        --with-python3-command=python3.8 \
        --with-python-config-dir=$HOME/.local/lib/python3.8/config-3.8-x86_64-linux-gnu \
        --enable-perlinterp=yes \
        --enable-cscope \
        --enable-luainterp \
        --with-lua-prefix=$HOME/.local \
        --prefix=$HOME/.local

没缺什么吧？

[glepnir]

能用dockerfile重现吗？你是自己build的吗。有些库需要挂vpn才能down把？

[edaplayer]

dockerfile没用过，我自己编译的vim，不需要vpn

[edaplayer]

换了14.04，一样的现象 ubuntu版本: ubuntu 12.04（64bit）， 14.04，64bit vim版本: vim8.2.1551 vim-devicons版本 commit 308526367703698554d19f15f692ee3c45a598cb Merge: 712d1ab 8bc6634 Author: IK 36619465+kazukazuinaina@users.noreply.github.com Date: Sat Aug 15 01:01:18 2020 +0900

[glepnir]

我在centos试了下没有重现。我装个ubuntu试试。

加载顺序有问题，icon_syntax调用得太早了 我加了两行log

结果先调用icon_syntax，才调用Filename颜色初始化函数 spaceline#colors#spaceline_hl('FileName', s:slc, 'aqua', 'purple','bold')

[edaplayer]

问题在于如何让space.vim早于syntax.vim运行？

[glepnir]

你这个顺序每次都是固定的？

[glepnir]

这里是加载，你把顺序换一下试试吧 https://github.com/hardcoreplayers/spaceline.vim/blob/71d6dbacb9c011b74f3e1043bebee6edbbdd80c1/autoload/spaceline.vim#L136-L137

[glepnir]

解决了应该在vim 8.2复现了。试了下没问题。

@glepnir This worked for me, thanks!
