如何将语法高亮添加到包含 Bash 中某些代码的字符串？
How to add syntax highlighting to a string containing some code in Bash?
我有一个包含一些基本 aidl 代码的变量（基本上只是一堆方法签名）。
我想以添加语法突出显示的方式回显该变量。例如用不同颜色显示方法名、数据类型和参数名。
我知道可以这样手工完成：
NC='3[0m' # no color
BLUE='3[0;34m'
RED='3[0;31m'
GREEN='3[0;32m'
# Wihtout syntax highlighting
echo "void verifyIntentFilter(int id, int verificationCode, in List<String> failedDomains);"
# With syntax highlighting
echo "${BLUE}void${NC} ${RED}verifyIntentFilter${NC}(${BLUE}int${NC} ${GREEN}id${NC}, ${BLUE}int${NC} ${GREEN}verificationCode${NC}, ${BLUE}in List<String>${NC} ${GREEN}failedDomains${NC});"
但是有几万行代码一直在变化，我不想一直重写脚本。是否有 Bash 命令来执行此操作？我认为如果有一个命令可以突出显示 Java 或 C++ 代码，那可能会起作用，因为 aidl 方法签名非常相似。
这是我的变量的一个例子：

使用 highlight 命令，我可以让语法高亮显示在一定程度上起作用，但它不能识别很多数据类型。例如，它适用于 boolean、int 和 byte，但不适用于 String、ComponentName、IOnPermissionsChangeListener 等。 .
echo "$CODE" | highlight --out-format=xterm256 --syntax=java
似乎更可靠的方法是使用某种正则表达式替换来逐行添加颜色。
例如
- 方法名称：在
( 字符开始之前结束 space
在 (. 之前找到
- 参数名称：a 之前的一个词
, 或 )（单词和
, 或 ).
- 数据类型：所有单词（分别不包括最后一个
一）在（
(和,）或（,和,）或（,和)之间，或
（beginning of line 和 (
但我想不出在 Bash 中实现它的合理方法。

步骤：
- 为您要解析的语法编写一个解析器。最好使用真正的编程语言，如 python 或 C++。标记输入并检测标记类型（函数 return 类型、函数标识符、参数类型、参数标识符等）。
- 将特定颜色应用于特定标记类型。
- 输出。
I can't think of a reasonable way to implement this in Bash.
我也想不出来，我相信，因为在 bash 中有 none 合理的方法来做到这一点。 Bash 是一种 shell，它不是一种完全易于使用的编程语言，速度也不快，它是一种 shell，主要用于 运行 其他 程序。考虑一种不同的语言。你可以瞄准 awk，但我会选择 python。
对于简单的情况，您可以将其写在正则表达式中。在 sed 或 awk 中（仍然 - 而不是 bash）并用一些正则表达式标记输入，应用颜色和输出，但我不相信你将能够处理前。 C++ 中的函数指针。
用 sed 编写的分词器示例，仅供娱乐：
echo 'void checkPackageStartable(String packageName, int userId);' |
sed '
s/^ *\([^(,)]\+\) \+\([^ (,)]\+\)\([(,)]\)\(.*\)/\n{FUNCRET}\n{FUNCNAME}\n{SEP}\n/;
h;
:a; {
/^ *\([^(,)]\+\) \+\([^ (,)]\+\)\([(,)]\)\([^\n]*\)\n\(.*\)$/{
s//\n{PARTYPE}\n{PARNAME}\n{SEP}\n/
b a
}
}
s/^;\(.*\)/{END};/
'
输出：
{FUNCRET}void
{FUNCNAME}checkPackageStartable
{SEP}(
{PARTYPE}String
{PARNAME}packageName
{SEP},
{PARTYPE}int
{PARNAME}userId
{SEP})
{END};
您可以修改此类 sed 脚本以应用来自某些变量的颜色而不是标记，并将输出中的换行符更改为空格以用于您请求的输出。
我有一个包含一些基本 aidl 代码的变量（基本上只是一堆方法签名）。 我想以添加语法突出显示的方式回显该变量。例如用不同颜色显示方法名、数据类型和参数名。
我知道可以这样手工完成：
NC='3[0m' # no color
BLUE='3[0;34m'

# Wihtout syntax highlighting

# With syntax highlighting
echo "${BLUE}void${NC} ${RED}verifyIntentFilter${NC}(${BLUE}int${NC} ${GREEN}id${NC}, ${BLUE}int${NC} ${GREEN}verificationCode${NC}, ${BLUE}in List<String>${NC} ${GREEN}failedDomains${NC});"
