It starts in `insert` mode. ##### autocompletion In insert mode, lobar will try to infer methods or argument from method/arg position and evaluated JSON at the current cursor position. ``/`` or ``/`` to navigate the completion list. ##### normal mode Hitting `esc` will drop you into normal mode, where you can move horizontally with `h`, `l`, `b`, `w`, `e`, `t`, `f`, `T`, `F`, `0`, and `$`. You can also use `c` and `d` with those movements in addition to `i` and `a` with a character or one of `{}[]{}'"`. Vertical movement ('j', 'k', ``, ``), will scroll the json output. `u` to undo and `` to redo. `y` will copy your current prompt input to your clipboard. `` to exit or `enter` to exit and print the currently evaluated json to `stdout`. ### caveats If you want to use a string argument for a method that collides with a lodash method name, you'll have to quote it twice: ```shell echo '[{"isString": true}]' | lbr filter "'isString'" [{"isString":true}] ``` This is because `lbr` tries to `eval` the argument with lodash as the context. ```shell echo '[{"isString": true}]' | lbr filter isString [] ``` ### environment variables You can set options using environment variables: ```shell $ LOBAR_PRETTY_PRINT=true lbr -d '{"foo": "bar"}' .foo > "bar" ``` ## why? I really like [jq](https://stedolan.github.io/jq/), but I have to look up the syntax all the time. As a javascript developer, I already know lodash, and it's generally enough for what I want to do at the command line. --- _Source: https://npm.io/package/lobar · Machine-readable twin of the npm.io package page.
