Delphi XE 10.4.2里面的LSP自动提示问题

nikotin 2021-05-15 09:26:42

看资料说Delphi XE 10.4.2下自动提示有两种模式：一种是classic code insight，一种是language service protocal。用了下发现lsp好像只能通过快捷键ctrl+space来开启启动提示，而不能像classic code insight那样随着输入会自动提示。请教各位，lsp能不能不用快捷键，而是随着代码输入自动提示呢？

虽然没用10.4，不过我相信不可能有这样的BUG，应该是设置的问题，可以请安装了10.4的解答一下，@秋天之落叶~~~

没反啊，不信老哥自己试试。启用lsp之后，就必须按ctrl+space才有代码提示了。真是烦得很。

说反了吧？！

需要先安装Patch1。 Patch 2 for RAD Studio 10.4 now available This patch addresses a number of issues in RAD Studio 10.4, pertaining to Delphi Compiler, the RAD Studio IDE in general and the new LSP-based Code Insight in particular, plus C++ Builder Android exceptions and some debugger issues. The installation of this patch requires a prior installation of Patch #1 (separately available on GetIt and in the download portal). Installing this patch is recommended for all RAD Studio 10.4 customers. Note that this patch is fairly large to download (around 190 MB). The patch includes detailed installation instructions as part of the Readme. Please read the steps carefully (or the corresponding steps in this blog post), as the GetIt download does not install the patch automatically. You must follow the instructions in order to install. Just using GetIt is not enough.

Delphi 10.4重点是实现了LSP，但现在最新的10.4.2还是不成熟，无法满足日常需要，不过没关系，可以设置为原有的方案，如下图：具体操作： Tools->Options->Editor->language->Code Insight: Code insight manager选择Delphi(Classic Code Insight) 取消Tooltip symbol insight 取消Error insight Save 现在就改回了原来的代码提示方

与以前的版本相比，在10.4.2中LSP为Delphi的错误洞察添加了许多新功能：编辑器现在为提示和警告以及错误显示彩色下划线，这意味着您可以在代码编辑器中看到潜在的重要问题，编辑器状态栏中当前文件的错误、警告和提示状态的摘要；以及几种突出显示问题代码的新方法，使查看有问题的代码更加容易。现在就改回了原来的代码提示方案，好消息是已经进入内测的10.4.2，重点还是增加与改进LSP的功能，坏消息是不确定能否达到实用状态，只能等发布后实际用下才能知道，不过从内测的说明中可以看到，真是增加与改进了不少功能。

这是官方的说明：https://blogs.embarcadero.com/rad-studio-10-4-2-general-patch-and-delphi-compiler-patch/ 这下官方的下载地址： http://altd.embarcadero.com/getit/public/libraries/Patches/CompilerPatch-20210430.zip 该补丁解决了10.4.2中的Delphi编译器中存在的性能问题以及内存占用问题，因此，该补丁也提升了Code Insi
