Moar is a pager. It's designed to just do the right thing without any configuration:
The intention is that Moar should work as a drop-in replacement for Less. If you find that Moar doesn't work that way, please report it!
Doing the right thing includes:
- Syntax highlight source code by default using Chroma
- Search is incremental / find-as-you-type just like in Chrome or Emacs
- Search becomes case sensitive if you add any UPPER CASE characters to your search terms, just like in Emacs
- Regexp search if your search string is a valid regexp
- Supports displaying ANSI color coded texts (like the output from
git diff
|riff
for example) - Supports UTF-8 input and output
- The position in the file is always shown
For compatibility reasons, moar
uses the formats declared in these environment variables when viewing man pages:
LESS_TERMCAP_md
: BoldLESS_TERMCAP_us
: Underline
Moar is used as the default pager by:
Installing
- Download
moar
for your platform from https://github.com/walles/moar/releases/latest chmod a+x moar-*-*-*
sudo mv moar-*-*-* /usr/local/bin/moar
And now you can just invoke moar
from the prompt!
If a binary for your platform is not available, please file a ticket or contact johan.walles@gmail.com.
Debian / Ubuntu
A Request for Packaging is open, please help!
Setting Moar as Your Default Pager
Set it as your default pager by adding...
export PAGER=/usr/local/bin/moar
... to your .bashrc
.
Issues
Issues are tracked here, or you can send questions to johan.walles@gmail.com.
Embedding
Here's one way to embed moar
in your app:
package main
import (
"bytes"
"fmt"
"github.com/walles/moar/m"
)
func main() {
buf := new(bytes.Buffer)
for range [99]struct{}{} {
fmt.Fprintln(buf, "Moar")
}
err := m.NewPager(m.NewReaderFromStream("Moar", buf)).Page()
if err != nil {
// Handle paging problems
panic(err)
}
}
m.Reader
can also be initialized using NewReaderFromText()
or
NewReaderFromFilename()
.
Developing
You need the go tools.
Run tests:
./test.sh
Run microbenchmarks:
go test -run='^$' -bench=. . ./...
Build + run:
./moar.sh ...
Install (into /usr/local/bin
) from source:
./install.sh
Making a new Release
Make sure that screenshot.png matches moar's current UI. If it doesn't, scale a window to 81x16 characters and make a new one.
Execute release.sh
and follow instructions.
TODO
-
Searching for something above us should wrap the search.
-
Enable exiting using ^c (without restoring the screen).
-
Start at a certain line if run as "moar.rb file.txt:42"
-
Redefine 'g' without any prefix to prompt for which line to go to. This definition makes more sense to me than having to prefix 'g' to jump.
-
Handle search hits to the right of the right screen edge. Searching forwards should move first right, then to the left edge and down. Searching backwards should move first left, then up and to the right edge (if needed for showing search hits).
-
Support viewing multiple files by pushing them in reverse order on the view stack.
-
Incremental search using ^s and ^r like in Emacs
-
Retain the search string when pressing / to search a second time.
Done
-
Add '>' markers at the end of lines being cut because they are too long
-
Doing moar on an arbitrary binary (like /bin/ls) should put all line-continuation markers at the rightmost column. This really means our truncation code must work even with things like tabs and various control characters.
-
Make sure search hits are highlighted even when we have to scroll right to see them
-
Change out-of-file visualization to writing --- after the end of the file and leaving the rest of the screen blank.
-
Exit search on pressing up / down / pageup / pagedown keys and scroll. I attempted to do that spontaneously, so it's probably a good idea.
-
Remedy all FIXMEs in this README file
-
Release the
go
version as the newmoar
, replacing the previous Ruby implementation -
Add licensing information (same as for the Ruby branch)
-
Make sure "git grep" output gets highlighted properly.
-
Handle all kinds of line endings.
-
Make sure version information is printed if there are warnings.
-
Add spinners while file is still loading
-
Make
tail -f /dev/null
exit properly, fix https://github.com/walles/moar/issues/7. -
Showing unicode search hits should highlight the correct chars
