A simple text reader, with lesser functionalities then less.
Build it with:
cargo build --release
Then you can use:
# Read a file:
lesser /path/to/filename
# help:
lesser --help
# Pipe a file:
cat file | lesser
- h: move left one column
- l: move right one column
- j: move down one row
- k: move up one row
- Down arrow: Move down one page
- Up arrow: Move up one page
- Left arrow: Move left one page
- Right arrow: Move right one page.
- Ctrl + C, q: Exit.
You can also run it with cargo using:
cargo run -- /path/to/filename
For showing logs:
LESSER_LOG=DEBUG cargo run -- /path/to/filename 2> /tmp/lesser.stderr
You need to redirect stderr to some file, otherwise the content of the file will override the printed log line.
- Ignore the new line at the end of the file (if there is any).
- If the output is redirected to anything other than a terminal, for example a pipe to another command, less behaves like cat.
- Implement more less's functionalities.
