The goal is to get more from logs than most of other pagers can. And to do so in less time.

Slit supports opening a single file (for now), or reading input from stdin. Slit is runs in terminal mode, writing directly to the screen, without cluttering the terminal buffer by all the logs you are reading.

The best way is to get Go on your system and compile yourself. It's easier then it sounds:

• download and install from https://golang.org/dl/
• make sure that you got $GOPATH/bin in your PATH.
• go get github.com/tigrawap/slit
• done!

If you prefer pre-built binaries, head over to the releases page - https://github.com/tigrawap/slit/releases. Keep in mind however they might be some commits behind master branch.

• / - Forward search
• ? - Backsearch
• n - Next match
• N - Previous match
• CTRL + / - Switch between CaseSensitive search and RegEx
• & - Filter: intersect
• - - Filter: exclude
• + - Filter: union
• = - Remove all filters
• U - Removes last filter
• C - Stands for "Context", switches off/on all filters, helpful to get context of current line (which is the first line, at the top of the screen)

• f, PageDown, Space - Page Down
• b, PageUp - Page Up
• g, Home - Go to first line
• G, End - Go to last line
• Arrow down, j - Move one line down
• Arrow up, k - Move one line up
• Arrow left, Arrow right - Scroll horizontally
• <, > - Precise horizontal scrolling, 1 character a time

• K - Keep N first characters(usually containing timestamp) when navigating horizontally
  Up/Down arrows during K-mode will adjust N of kept chars
• W - Wrap/Unwrap lines
• q - quit

Both search and filters currently support the CaseSensitive and RegEx modes. To switch between modes press CTRL + / in search/filter input.

TODO: History does not preserve mode of previous searches. Will be improved soon

Note: For case-insensitive search in RegEx use (?i)cOnDiTiOn
TODO: This will be replaced with separate toggle in the future

• --follow -f Follow file/stdin. All filters are applied to new data.
  When navigating up from the end, following will be stopped and resumed on navigating to the end(shift+g) or just by scrolling down till the end
• --version Displays version

• Inclusive(&): Will keep only lines that match the pattern AND included by previous filters
• Exclusive(-): Filters out lines that match the pattern
• Appending(+): Filters in lines that match pattern, even if they were excluded by previous filters

Filters can be chained - The first 'append' filter (if it is the first to be used) will work as inclusive filter. When adding filters the active line position (at top of screen) will remain the same (as possible).

Chaining of filters gives ability to filter out all the 'noise' dynamically, and get to what you're actually looking for.

Imagine you have huge log file with hundreds of thousands of lines from multiple threads.
And all that you are interested in are logs from "Thread-10, "MainThread", not interested in "send" and "receive" messages
In addition, you want to see "Exception", even if it is on line that were excluded by previous filters.

The following chain of filters will output the expected result:

&Thread-10  
+MainThread  
-receive  
-send  
+Exception

• Complex include/exclude filters, that will allow: (DEBUG OR INFO) AND NOT (send OR receive OR "pipe closed")
• Filters menu for overviewing current filters, removal, reordering or disable some temporary
