基本配置
方法一
查看所有命令：
gsettings list-recursively | grep -i gedit
命令解釋
gsettings set org.gnome.gedit.preferences.editor tabs-size 4
//設置縮進
gsettings set org.gnome.gedit.preferences.editor auto-save true
//設置自動保存
gsettings set org.gnome.gedit.preferences.editor auto-indent true
//設置自動縮進
gsettings set org.gnome.gedit.preferences.editor bracket-matching true
//設置顯示匹配括號
gsettings set org.gnome.gedit.preferences.editor display-line-numbers true
//設置行號
gsettings set org.gnome.gedit.preferences.editor highlight-current-line true
//設置高亮
bash代碼
gsettings set org.gnome.gedit.preferences.editor tabs-size 4
gsettings set org.gnome.gedit.preferences.editor auto-save true
gsettings set org.gnome.gedit.preferences.editor auto-indent true
gsettings set org.gnome.gedit.preferences.editor bracket-matching true
gsettings set org.gnome.gedit.preferences.editor display-line-numbers true
gsettings set org.gnome.gedit.preferences.editor highlight-current-line true
gsettings set org.gnome.gedit.preferences.editor create-backup-copy false
gsettings set org.gnome.gedit.plugins active-plugins "['docinfo', 'filebrowser', 'zeitgeistplugin', 'snippets', 'spell', 'time', 'externaltools', 'modelines']"
升級版本
#!/bin/bash
if [ `gsettings get org.gnome.gedit.preferences.editor display-line-numbers` == true ]; then
echo "檢測到舊的 gedit 配置, 移動至 /tmp/gedit 目錄"、
[ -d /tmp/gedit ] && rm /tmp/gedit -r
mv /home/hzoi/.config/gedit /tmp
fi
echo -e "Tab 大小\t: 4\n自動保存\t: true\n自動縮進\t: true\n括號匹配\t: true\n顯示行號\t: true\n高亮當前行\t: true\n創建備份文件\t: true"
gsettings set org.gnome.gedit.preferences.editor tabs-size 4
gsettings set org.gnome.gedit.preferences.editor auto-save true
gsettings set org.gnome.gedit.preferences.editor auto-indent true
gsettings set org.gnome.gedit.preferences.editor bracket-matching true
gsettings set org.gnome.gedit.preferences.editor display-line-numbers true
gsettings set org.gnome.gedit.preferences.editor highlight-current-line true
gsettings set org.gnome.gedit.preferences.editor create-backup-copy false
echo -e "啟用插件\t: externaltools"
gsettings set org.gnome.gedit.plugins active-plugins "['docinfo', 'filebrowser', 'zeitgeistplugin', 'snippets', 'spell', 'time', 'externaltools', 'modelines']"
echo -e -n "請輸入主題前的數字(默認為0):\n\t(0) classic\n\t(1) tango\n\t(2) oblivion\n\t(3) kate\n\t(4) cobalt\n> "
read scheme
listscheme=(classic tango oblivion kate cobalt)
scheme=${listscheme[${scheme:-0}]:-classic}
gsettings set org.gnome.gedit.preferences.editor scheme $scheme
echo "gedit 主題已被設置為 $scheme"
echo "正在下載外部工具..."
wget http://files.cnblogs.com/files/youxam/gedit.tar.gz -q
wget http://files.cnblogs.com/files/youxam/bin.tar.gz -q
echo "正在解壓..."
tar xzvf gedit.tar.gz -C /home/hzoi/.config > /dev/null
tar xzvf bin.tar.gz -C /home/hzoi/ > /dev/null
rm gedit.tar.gz
rm bin.tar.gz
echo "PATH=\${PATH}:/home/hzoi/.bin" >> /home/hzoi/.bashrc
source /home/hzoi/.bashrc
echo "正在下載 vim配置文件 ..."
wget http://files.cnblogs.com/files/youxam/.vimrc.js -O .vimrc -q
rm config.sh
保存文件為 set.sh
終端運行 sh ./set.sh
方法二
直接通過編輯-首選項進行設置，太過簡單不多描述。
編譯配置
首先通過編輯-首選項-插件-外部命令來打開外部命令，然后在工具-Manage External Tools來添加新工具，工具代碼使用bash語言。
代碼使用方式：+添加新插件，在編輯框中粘貼代碼，快捷鍵：自定義，保存為：當前文檔，輸入為：當前文檔，輸出為：在下方面板中顯示，適用范圍為：所有文檔 C++。
下面提供兩種代碼：
代碼一：
#!/bin/sh
dir=$GEDIT_CURRENT_DOCUMENT_DIR
name=$GEDIT_CURRENT_DOCUMENT_NAME
pre=${name%.*}
g++ $dir/$name -o $pre -g -Wall
if test $? -eq 0; then
gnome-terminal -x bash -c "$dir/$pre;echo;read;"
fi
這種代碼會打開一個終端，然后需要手動輸入。調試代碼時，比較繁瑣。
那么我們就搞了一個更簡單的方式。代碼如下：
代碼二
#!/bin/sh
fullname=$GEDIT_CURRENT_DOCUMENT_NAME
dir=$GEDIT_CURRENT_DOCUMENT_DIR
name=${fullname%.*}
inname=${name}.input
outname=${name}.output
ansout=${name}.ansout
cd $dir
cat $fullname | awk 'BEGIN{a=0} /\*\//{a=1} a==0{print $0}' | grep -v "\/\*" | cat > $inname
cat $fullname | awk 'BEGIN{a=0} /\*\//{a++} a==1{print $0}' | grep -v ["*\/""\/*"]| cat >$outname
g++ $fullname -o $name && ./$name <$inname >$ansout
diff -a -b -B -c -q $ansout $outname && echo Accept || echo Wrong Answer
cat $ansout
rm $ansout $outname $inname $names -rf
這個版本無需文件輸入輸出，只需要在文件頭加入兩個注釋，第一個為樣例輸入，第二個為樣例輸出。
舉個例子：
/*
6
1 30 3 2 3 4
2 16 2 5 6
3 5 0
4 4 0
5 11 0
6 5 0
*/
/*
25
*/
#include <iostream>
using namespace std;
....<code>
這樣在編譯時會在下方面板輸出
Running tool: 運行命令
25
Done.
主題配置
在編輯-首選項-字體和顏色中有許多配色方案可以選擇，這里我們在推薦一個，同樣附上源碼：

把它保存為a.xml。然后在回到編輯-首選項-字體和顏色中點擊 + 號，然后選擇a.xml文件，便可以添加主題。（ps：有推薦者歡迎在下面留言，謝謝）。
自動補全
gedit的自動補全叫做片段，不像vscode，gedit的片段只能進行一些簡單的操作，比如打出for，然后按下tab鍵，這樣會出現一個
for (unsigned int i = 0; i < count; i += 1)
{
}
的代碼片段，然后就可以通過移動tab鍵，來改變各個參量的值。同時可以通過工具-Manage Snippets來管理片段。
嗯，就這些吧，若有疑問，隨時留言。
