# TODO
## Performance
It's currently very clunky on the rpi2.
## Custom help for command
eg: command "something", help: "does stuff", root: true do ... end
## Pipes and filters
* `Tool::DSL#run` is currently somewhat awkward; it would be simpler if returned an `Enumerator`, which could then be filtered (ie: highlight/grep), or concatenated to other `Enumerator`s.
## Streaming pipes with colours
* Make the `run` command able to grep the output while streaming the results to the screen.
* Make run pretend to be a tty, so I don't need `--color=always`.
* Use spawn, like so:
```
r,w = IO.pipe
spawn(*%w[echo hello world], out: w)
spawn(*%w[tr a-z A-Z], in: r)
```
## More package managers
Currently missing:
* RedHat/Fedora/CentOS
* OSX
* FreeBSD
* OpenBSD
* SuSE
## Dependency-fetching features
* Use upm to fetch dependencies for any library or script, across any language.
* Some kind of manifest file (or personifest, to be politically correct)
* This is a little like bundler, npm, etc., but for any type of package.
## Ability to install any package from any OS to the user's home directory
Slurps up the packages and their dependencies, then unpacks them into ~/.upm/{bin,lib} or something.
(Like nix?)

## fzf
Use fzf for "list" output (or other commands that require selecting, like "remove")
## Commandline argument parser
* Add options to commands:
* upm upgrade --download-only
* upm install --help
* upm help install
## Figure out how to integrate language package managers
* The packages that you can get through gem/pip/luarocks/etc. are often duplicated in the OS-level package managers. Should there be a preference?
* Should the search command show matches from all available package tools? (There could be a configure step where the user says which package managers should be included, and which have preference)
* Possibilites:
* upm install --ruby
* upm install ruby:,
* upm --ruby search
* upm ruby:search
* upm search os:
* Separate tool: `lpm search ` searches only language packages
* Add detectors for language-specific package-managers
* Help screen needs to display language-specific package managers
* `upm help --ruby` should show available ruby commands
## Give identical output on every platform
* Requires parsing the output of every command into a canonical format, or reading the package databases directly.
## apt: Integrate 'acs' wrapper script
## Evaluate UPM::Tool.new block in an instance of an anonymous subclass of UPM::Tool
This will allow tools to create classes and modules inside the UPM::Tool block without namespace collisions
## Themes?
Why not!
## Mirror Selector
Do a ping test on available mirrors, and use fzf to select.
## Interrupt catcher
Don't print backtrace when ^C is pressed.
## Tests
Create fake OS environments that you can chroot into and run upm to test it out.
# DONE
## Abbrev cmds
* eg: upm install => upm i => u i
