#419 更改列表项的格式

current format (for half the current list. currently, not all entries include links to crates) * kbknapp/clap-rs [clap] — a simple to use, full featured command-line argument parser * docopt/docopt.rs [docopt] — a Rust implementation of DocOpt * TeXitoi/structopt [structopt] — parse command line argument by defining a struct * killercup/quicli [quicli] — quickly build cool CLI apps in Rust * proposed changes * present the name of the project/library first, which brings it closer to the name used in a cargo.toml in many cases. keep it linked to the repository. * remove build passing icon. the page makes many requests to travis for badge SVGs. especially from a slower connection, the loading of the badges move the page as they affect the vertical spacing of the lists. if a user jumps or scrolls to the bottom of the page upon opening, they may need to wait before the page stays still. this change loses a nice splash of color the list, but reduces load times and prevents the unaligned badges slowing and littering the page. * move crates links a sub-list. this gives the description breathing room and allows us to include additional information/links on the sub-list, e.g. a direct link to the docs. * proposed format * clap — a simple to use, full featured command-line argument parser. * crates.io - docs * docopt — a Rust implementation of DocOpt. * crates.io - docs * structopt — parse command line argument by defining a struct. * crates.io - docs * quicli — quickly build cool CLI apps in Rust. * crates.io -
