ASCIIGenome is a genome browser based on command line interface and designed for running from console terminals.
Since ASCIIGenome does not require a graphical interface it is particularly useful for quickly visualizing genomic data on remote servers while offering flexibility similar to popular GUI viewers like IGV.
Documentation is at readthedocs/asciigenome.

This a list of available commands with their brief description.
For help on individual commands use one of::
command -h
?command
help command
e.g. `ylim -h`
N a v i g a t i o n
goto chrom:[from]-[to]
Go to region `chrom:from-to` or to `chrom:from` or to the start of
`chrom`.
INT from [c | to]
Go to position `from` or to region `from to` on current chromosome.
PERCENT from [c | to]
Zoom into the current window delimited by given PERCENT of screen.
+ INT [k|m]
Move forward by `INT` bases. Suffix K/M recognized.
- INT [k|m]
Move backwards by INT bases. Suffix K/M recognized.
f [NUM=0.1]
Move forward NUM times the size of the current window, 1/10 by default.
b [NUM=0.1]
Move backward NUM times the size of the current window, 1/10 by default
ff
Move forward by 1/2 of a window. A shortcut for `f 0.5`
bb
Move backward by 1/2 of a window. A shortcut for `b 0.5`
zi [INT = 1]
Zoom in INT times. Each zoom halves the window size.
zo [INT = 1]
Zoom out INT times. Each zoom doubles the window size.
extend [mid|window] [INT left] [INT right]
Extend the current window by `INT` bases left and right.
l
Go to the Left half of the current window.
