基于 url 和 clap 的命令行URL格式化器。

使用以下命令安装： cargo install furl

示例

$ furl -u "postgres://usr:pwd@localhost:5432/db" \
       -f "host='%h' port='%p' db='%A' user='%U' pwd='%P'"
host='localhost' port='5432' db='db' user='usr' pwd='pwd'

$ furl -u "https://www.google.com/search?q=rust+furl" \
       -f "scheme='%s' query='%q' path='%a' port='%p'"
scheme='https' query='q=rust+furl' path='/search' port=''

$ furl -u "https://en.wikipedia.org/wiki/Rust#Prevention" \
       -f "path='%a' fragment='%f'"
path='/wiki/Rust' fragment='Prevention'

$ furl -u "postgres://usr:pwd@localhost:5432/db"
postgres localhost 5432 db usr pwd  

格式化字符串可以包含以下任何一种替换

%A - the path, without the starting '/'
%a - the path
%f - the fragment
%h - the hostname
%P - the password of the userinfo portion
%p - the port
%q - the query string
%s - the scheme
%U - the username of the userinfo portion
%n - newline (\n)
%t - tab (\t)
%% - a single %

Bash示例

echo 'DATABASE_URL="postgres://webapp:pwd@localhost:5432/myapp"' >> .env

DPG="docker run -d --rm --name pg-%A -v vol-%A:/var/lib/postgresql \
    -p %p:5432 \
    -e POSTGRES_DB=%A -e POSTGRES_USER=%U -e POSTGRES_PASSWORD=%P \
    postgres"

$(source .env && furl -u $DATABASE_URL -f "$DPG")
