sbt - TERM=Apple_Terminal 在 macOS Sierra 10.12.3 上的奇怪问题

Question

我将我的 MacBookPro 升级到 macOS Sierra 并遇到了一个非常奇怪的行为。

首先，我按照文档中的建议使用 brew 安装 sbt: http://www.scala-sbt.org/download.html

这是一个简单的测试:

cd /tmp; echo $TERM; mkdir AT; cd AT; sbt -no-share -no-global -sbt-create

在查看堆栈跟踪时，我了解到 sbt 使用 jline使用“infocmp”进程查询终端的功能。

在这种情况下，它显示:

确实，'acsc' 行与 jline 试图解析为数字的内容相匹配。

切换终端有效:

与 TERM=xterm-256color 相同的行为。

我对此感到困惑。

有人遇到过这个问题吗？

Answer 1

jline(和 jline2)使用 naive parser

Matcher m = Pattern.compile("\\s*(([^,]|\\\\,)+)\\s*[,$]").matcher(lines[i]);

无法处理显示的输入。除其他遗漏外，it looks for a # character , 确定它是 numeric 功能及其 value 的术语信息分隔符，并尝试解析 # 作为一个整数。所以而不是看到

acsc=+\335\,\334-\366.\3770#`\327a\:f\241g\261h#i\360jjkkllmmnno\370p\370q\321rrssttuuvvwwxxy\262z\263{\271|\255}\243~\245,

作为

acsc
=
+\335\,\334-\366.\3770#`\327a\:f\241g\261h#i\360jjkkllmmnno\370p\370q\321rrssttuuvvwwxxy\262z\263{\271|\255}\243~\245,

(其中值是一组字符映射)，它看到

acsc=+\335\,\334-\366.\3770#`\327a\:f\241g\261h
#

Apple 在其基本系统中提供长期过时的软件的习惯使问题更加严重。如果您碰巧安装了更新的东西，无论是使用 MacPorts 还是其他东西，nsterm acsc 的条目将具有不同的值:

acsc=``aaffggjjkkllmmnnooppqqrrssttuuvvwwxxyyzz{{||}}~~,

这只是一个一对一的映射(例如，“vt100”)。

问题中显示的那个名为 nsterm+mac , 对应于 nsterm-old (在 October 2009 中重命名)。该条目在 September 2010 中重新格式化(重新排序映射以如图所示)，但出于实用目的，自 2009 年以来已过时。

ncurses terminfo(5)手册页假定读者对语法有所了解。 X/Open 对此进行了记录，例如 Formal Grammar .
