ghdl

Memorize ghdl as github download

ghdl is a fast and simple program (and also a golang module) for downloading and installing executable binary from github releases.

The demo above extracts fd execuable to current working directory and give execute permission to it.

Features

• Auto decompressing and unarchiving the downloaded asset (without any system dependencies like tar or unzip)

  Currently supporting unarchiving `tar` and decompressing `zip` `gzip`.
  Package format `deb` `rpm` `apk` will be downloaded directly

  ghdl binary is statically linked, works well on non-FHS *nix systems like NixOS). In case this is relevant to you, on that kind of system, only binaries like ghdl can be run directly.

• Setups for executable: ghdl moves executable to specified location and add execute permissions to the file.

• Auto filtering: multiple assets in one release will be filtered by OS or ARCH. This feature can be disabled using -F flag.

• Interactive TUI: when auto filtering is failed or returned multiple options, you can select assets in a interactive way, with vim key bindings support.

• Release tags: ghdl downloads latest release by default, other or old tagged releases can be downloaded by specifying release tag: username/repo#tagname

• Inspect download status with real-time progress bar.

Installation

If you're going to use ghdl as a go module, ignore the following installation progress.

• Using Go tools:

  go will download the latest version of ghdl to $GOPATH/bin, please make sure $GOPATH is in the PATH:

  go install github.com/beetcb/ghdl/ghdl@latest

  Note: Just to be safe, you'd better specify CGO_ENABLED=0 when running go install on non-FHS *nix systems like NixOS)

• Download and run executable from release.

• Run the following shell script(*nix system only):

  curl -fsSL "https://bina.egoist.sh/beetcb/ghdl?dir=/usr/local/bin" | sh
  # feel free to change the `dir` url param to specify the installation directory.

Usage

CLI

Run ghdl --help

❯ ghdl --help

ghdl download binary from github release
ghdl handles archived or compressed file as well

Usage:
  ghdl <user/repo[#tagname]> [flags]

Flags:
  -f, --asset-filter string   specify regular expression for the asset name; used in conjunction with the platform and architecture filters.
  -F, --filter-off            turn off auto-filtering feature
  -h, --help                  help for ghdl
  -n, --name string           specify binary file name to enhance filtering and extracting accuracy
  -p, --path path             save binary to path and add execute permission to it (default ".")

It's tedious to specify -p manually, we can alias ghdl -p "$DirInPath" to a shorthand command, then use it as a executable installer.

Go Module

1. Require ghdl to go.mod

   go get github.com/beetcb/ghdl

2. Use ghdl's out-of-box utilities: see TestDownloadFdBinary func as an example
