Hot Reload 方便修改程式後, 讓程式自動編譯並執行. 省去每次手動編譯與執行.
記錄一下目前自己使用過的三個套件Air, Fresh, Realize
1. Air (https://github.com/cosmtrek/air)
- 較推薦使用此套件
- 原先是使用 fresh, 但是遇到fresh不能在執行指令後面帶參數.
features
- Colorful log output
- Customize build or binary command
- Support excluding subdirectories
- Allow watching new directories after Air started
- Better building process
Installation
# binary will be $(go env GOPATH)/bin/aircurl -sSfL https://raw.githubusercontent.com/cosmtrek/air/master/install.sh | sh -s -- -b $(go env GOPATH)/bin# or install it into ./bin/curl -sSfL https://raw.githubusercontent.com/cosmtrek/air/master/install.sh | sh -sair -v
Usage
# 初始化設定檔air init# 預設找 .air.toml 此設定檔air# 選擇要執行的設定檔air -c .air.toml# Debugair -d
sample config

2. Fresh (https://github.com/gravityblast/fresh)
- 目前看起來沒在更新了
- 沒法在指令後面帶入參數
- 如果go build返回錯誤, 會將記錄在tmp資料夾中
Installation
go get github.com/pilu/freshUsage
fresh# 選擇要執行的設定檔fresh -c other_runner.conf

3. realize (https://github.com/oxequa/realize)
features
- High performance Live Reload.
- Manage multiple projects at the same time.
- Watch by custom extensions and paths.
- All Go commands supported.
- Switch between different Go builds.
- Custom env variables for project.
- Execute custom commands before and after a file changes or globally.
- Export logs and errors to an external file.
- Step-by-step project initialization.
- Redesigned panel that displays build errors, console outputs and warnings.
總結
目前較推薦使 air , fresh 遇到無法帶入參數, 且可設定的東西較少決了. realize 忘了之前是mod還是vendor無法安裝, 不知道解了沒.
