Coqide8.5: Linux上没有语法突出显示

Question

我安装了Coqide8.5w/ nix。不幸的是，所有面板的文本都是blakc；没有任何类型的语法突出显示(否则，8.5似乎比我安装的8.4有很大的改进)。我还得到以下信息：

(coqide:17272): GtkSourceView-WARNING **: Unknown parent scheme 'classic' in scheme 'coq_style'

(coqide:17272): GtkSourceView-WARNING **: Failed to load '/nix/store/2sxcqfc4q3ls4g2q13n1zwfhnydvgq-coq-8.5pl1/share/coq/coq.lang': could not find the RelaxNG schema file

cat ~/.nix-profile/share/coq/coq_style.xml输出

<?xml version="1.0" encoding="UTF-8"?>

给出第一个警告，我想应该有其他的东西，而不是"classic"，但是

我安装了libgtksourceview3.0-common，但是CoqIDE依赖于libgtksourceview2.0-common。安装后一个修复了它

Answer 2

我刚刚遇到了同样的问题，coqide是通过nix安装的(在coq-8.6包中)。

下面是一个脚本，它安装到您的homedir中的一些文件的符号链接来处理几条警告消息：

## Find the nix-installed version of the GTK SourceView 2.0 library
sourceview="$(nix-env -q coq --no-name --out-path |
    xargs nix-store -q --references |
    grep -- -gtksourceview-)"

## Link files into the correct hierarchical folders in your home dir:
share=share/gtksourceview-2.0
for file in language-specs/language2.rng \
    language-specs/def.lang \
    styles/classic.xml
do
    target="$HOME/.local/$share/$file"
    mkdir -vp "$(dirname "$target")"
    ln -vfns "$sourceview/$share/$file" "$target"
done

这修复了以下GtkSourceView-WARNING：

## fixed by language-specs/language2.rng
Failed to load '.../share/coq/coq.lang': could not find the RelaxNG schema file

## fixed by language-specs/def.lang
in file .../share/coq/coq.lang: style 'def:comment' not defined
Failed to load '.../share/coq/coq.lang': unable to resolve language 'def'

## fixed by styles/classic.xml
Unknown parent scheme 'classic' in scheme 'coq_style'

我可能会尝试在某个时候修复coq派生，以避免需要这种解决办法。我怀疑下列任何一项或两项措施都需要进行：

• 修正coq如何设置GTK SourceView搜索路径(因为它包含语言定义)
• 修正gnome2.gtksourceview如何导出其搜索路径以供其他程序使用
