如何设置 R 使用我的终端的所有宽度？

3

我R在终端中运行交互式，但它并没有使用终端的所有宽度。它只使用了 226 个字符中的 72 个字符。读取任何以交互方式显示的有很多列的数据都非常不舒服R。

我正在urxvt使用debian 9,8.

如何在vim中拆分打开多个手册页？

1

从View man pages in Vim 中，我学习了如何通过添加以下行来打开man页面：vim~/.vimrc

" Enable viewing man page in vim by ":Man ..."
runtime ftplugin/man.vim
" Set keyword 'K' to use ":Man ..." to view man pages in vim
set keywordprg=:Man

但是，这只能对Man每个tab. 我想要的是Man在不同的拆分中打开不同的页面。

降级 libfontconfig1 导致 Fontconfig 错误

1

在构建的过程中dwm，提示X11/Xft/Xft.h找不到，apt-get无法安装，因为libfontconfig1需要2.13.0-5while 2.11.0。

所以我将其降级libfontconfig1为2.11.0-6.7+b1using aptitude，安装libxft-dev:amd64 (2.3.2-1+b2)并成功编译，但是当我在注销并再次登录后dwm尝试使用时，我发现它不起作用。dmenu

我尝试使用apt-get重新安装2.13.0，但没有找到。

PS在这个过程中，我使用了错误的sudo apt-get autoremove删除suckless-tools，不得不dmenu从源代码重新构建并重新安装。

我尝试bash从urxvt打开运行它并从shift + alt + enter以下输出dmenu：

为什么 sed 做的比我问的更多？

-1

当我申请sed -i -e "s/..\///" -e "s/type_properties\///" testfile以下文件时：

#include "../../../../include/concepts/type_properties/operations/has_or_op_v.hpp"

int main() {
    // Test has_not_op_v.
}

它输出这个：

#include "../../../include/concepts/operations/has_or_op_v.hpp"

int main() {
  / Test has_not_op_v.
}

我只是想 sed 删除一个../并 delete type_properties/，但这也破坏了我的注释。

我试图通过以下方式解决此问题：

用于 cmake --build . --target clean删除构建的文件并cmake --build .再次运行。
按照上面给出的说明，将目录更改为 lib，然后运行ranlib libLLVMSupport.a.

但这些都不起作用：我又跑cmake --build .了，他们给了：

我在方法2中检查了lib/libLLVMSupport.a的时间戳，发现它没有改变，意味着它不是由cmake --build ..
