fzf in rust

[lotabout]

FZF is a very handy tool to do fuzzy search. I would like to write one on my own with rust. The main purpose is to learn rust by practice.

Use this issue as project management

TODOs:

• [x] Better threading, currently the reader/matcher will block input thread if they are so busy, that should be avoid.
• [x] a better display. Which should adjust the matched position.
• [x] readline utilities. That means for example Ctrl-A to go tot the first character, etc...
• [x] color support.
• [x] save a selected array instead of embedded the info into the item which will cause delay when exit.
• [x] handle terminal resize event.
• [x] remap key. (mechanism OK, need to add detail key/action)
• [x] cache for queries.

Now the problem is that the controller will save all items read before send the NewItem event to matcher. Meanwhile the matcher keeps going because no signal is received. And since the controller will need to lock the data of items and that lock is not released by matcher. Kind of deadlock here.

The comments below are Wrong...

About the block issue: the root cause is that every time a new query starts, fzf-rs will reset the item_pos to 0, thus will trigger for item in items[self.item_pos..].into_iter() {. In this case, it seems that [start..] will try to read all items instead of lazy.

So In this case, we should directly specify the bounds of the slice, i.e. [start..end]. Problem solved.

Closing this because almost what I planned in the first place had been done. Check skim.
