NeoVim调试Python、Golang

Jan 21, 2022

在上两篇中NeoVim开发环境配置、NeoVim配置Go开发环境(进阶), 完成了将NeoVim作为IDE最基本常用功能的，这里将进一步完成对Python、Golang调试环境的配置。

在NeoVim上进行调试（Python、Golang）有nvim-dap和vimspector可做选择，这里将使用vimspector进行调试工作。

插件安装

在plug.vim中添加：

Plug 'puremourning/vimspector'

:PlugInstall安装插件。在init.vim中，添加：

let g:vimspector_enable_mappings='HUMAN'

将vimspector 快捷键映射配置为HUMAN模式：

Key	Mapping	Function
`F5`	`<Plug>VimspectorContinue`	When debugging, continue. Otherwise start debugging.
`F3`	`<Plug>VimspectorStop`	Stop debugging.
`F4`	`<Plug>VimspectorRestart`	Restart debugging with the same configuration.
`F6`	`<Plug>VimspectorPause`	Pause debuggee.
`F9`	`<Plug>VimspectorToggleBreakpoint`	Toggle line breakpoint on the current line.
`<leader>F9`	`<Plug>VimspectorToggleConditionalBreakpoint`	Toggle conditional line breakpoint or logpoint on the current line.
`F8`	`<Plug>VimspectorAddFunctionBreakpoint`	Add a function breakpoint for the expression under cursor
`<leader>F8`	`<Plug>VimspectorRunToCursor`	Run to Cursor
`F10`	`<Plug>VimspectorStepOver`	Step Over
`F11`	`<Plug>VimspectorStepInto`	Step Into
`F12`	`<Plug>VimspectorStepOut`	Step out of current function scope

Adapter安装

下面是各个语言调试使用的Adapter：

Python --- debugpy
Go --- delve

通过:VimspectorInstall debugpy，:VimspectorInstall delve 完成对python、go 调试adapter的安装。

调试Python

由于NeoVim的LSP指定当前根目录是各LSP Server提供的功能，在调试Ptyon时，在目录中添加.pyrightconfig.json文件：

{
    "executionEnvironments": [
        {"root": "."}
    ]
}

如上配置，将.pyrightconfig.json文件所在目录，作为Root目录。

配置调试器，添加配置文件 .vimspector.json：

{
    "configurations": {
        "run": {
            "adapter": "debugpy",
            "default": true,
            "configuration": {
                "request": "launch",
                "type": "python",
                "cwd": "${workspaceRoot}",
                "stopOnEntry": true,
                "program": "${file}"
            },
            "breakpoints": {
                "exception": {
                    "raised": "N",
                    "uncaught": "",
                    "userUnhandled": ""
                }
            }
        }
    }
}

configuration.program指定要调试的程序，可以通过configuration.env配置调试时程序的环境变量，configuration.args配置参数。如在调试一个scrapy的爬虫程序时，通过program指定scrapy位置，args指定启动的具体spider：

{
    "configurations": {
        "run": {
            "adapter": "debugpy",
            "default": true,
            "configuration": {
                "request": "launch",
                "type": "python",
                "program": "~/opt/miniconda3/envs/p3/bin/scrapy",
                "cwd": "${workspaceRoot}",
                "stopOnEntry": true,
                "args": ["crawl", "${fileBasenameNoExtension}"]
            },
            "breakpoints": {
                "exception": {
                    "raised": "N",
                    "uncaught": "",
                    "userUnhandled": ""
                }
            }
        }
    }
}

调试Go

配置调试器，添加配置文件 .vimspector.json，如：

{
    "configurations": {
        "default": {
            "adapter": "delve",
            "default": true,
            "configuration": {
                "request": "launch",
                "mode": "debug",
                "cwd": "${workspaceRoot}",
                "stopOnEntry": true,
                "program": "${file}",
                "args": [
                    "-http_addr","localhost:8084"
                ]
            },
            "breakpoints": {
                "exception": {
                    "raised": "N",
                    "uncaught": "",
                    "userUnhandled": ""
                }
            }
        }
    }
}

指定adapter为delve来调试go程序，program指定要调试的程序文件，args指定参数http_addr=localhost:8084
