Question

我想把html片段传递给pygmentize来相应地着色它。我想知道如何使用sed或其他一些cli工具来实现这一目标。

我尝试了一堆sed one-liners并尝试使用以下SO问题：

我有以下日志：

org.codehaus.jackson.JsonParseException: Unexpected character ('<' (code 60)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')
at [Source: java.io.StringReader@369133f6; line: 1, column: 2]

更新我将此添加到更长的命令中：

mvn -U test | (while read line; do echo ${line} | sed -e "s/.*ERROR.*/`echo -e '\e[91m&\e[0m'`/g" -e "s/.*\(WARN|INFO\).*/`echo -e '\e[93m&\e[0m'`/g"; done)

Answer 1

cat log | awk'/＆lt; html＆gt; /，/＆lt; \ / html＆gt; /'

应该这样做。

要删除第一个html标记之前的“废话”，请使用sed将html标记放在它自己的行上。

cat log | sed's /＆lt; html＆gt; / \ n＆lt; html＆gt; /'| awk'/＆lt; html＆gt; /，/＆lt; \ / html＆gt; /'

Answer 2

TXR：

为了便于说明，我们将pygmentize替换为用X替换HTML中每个字母的命令。

@;; replace with .e.g. pygmentize
@(bind filter "tr [A-Za-z] X")
@date @time @pid [@function] @error_1
@error_2 <html>
@(collect)
@stuff
@(last)
</html>
@(end)

@error_3
@(output)
@date @time @pid [@function] @error_1
@error_2
@(end)
@(output `!@filter`)
<html>
@{stuff "\n"}
</html>
@(end)
@(output)
@error_3
@(end)

试运行：

$ txr  log.txr  log.txt

Answer 3

我将此作为较长命令的一部分使用：

mvn -U test | (while read line; do echo ${line} | sed -e "s/.*ERROR.*/`echo -e '\e[91m&\e[0m'`/g" -e "s/.*\(WARN|INFO\).*/`echo -e '\e[93m&\e[0m'`/g"; done)

sed multiline pygmentize
