How to syntax highlight via Less
is there a way to syntax highlight a file I see in Less?
actually I'm using this command to open an xml file (and sometimes a series of them)
less htmleditors/htmleditors_config.xml
or
less [multiple files]
I'd like to stay in Less (to learn that program better and to use my knowledge of :n and :p for next/previous navigation)
But it also want some kind of basic syntax highlighting – at least show the comments differently. Do you know any way to do it?

You can use GNU's source-highlight, as shown here (path may differ, see below):
export LESSOPEN="| /usr/bin/src-hilite-lesspipe.sh %s"
export LESS=' -R '
As of Debian Stretch and Fedora 25, package names and script paths differ
Debian:
sudo apt install libsource-highlight-common source-highlight
dpkg -L libsource-highlight-common | grep lesspipe
# /usr/share/source-highlight/src-hilite-lesspipe.sh
Fedora:
sudo dnf install source-highlight
rpm -ql source-highlight | grep lesspipe
# /usr/bin/source-highlight/src-hilite-lesspipe.sh
I retrieve the following error message when I runless ~/.zshrc
. Error:src-hilite-lesspipe.sh: line 9: source-highlight: command not found
. I run this on MacOSX.

Best of both previous answers: you can invoke system default editor from within less, by pressing v.

pygmentize somefile.ex | less -R
or
function cless () {

Pygmentize comes as a part of the Pygments Python syntax highliter.

I think that you should use a text editor. I like vim myself. That will give you LOTS of power when viewing files and then when you want to edit them you will already know the basics.
Here are some of the advantages of using a text editor (specifically vim):
- syntax-highlighting
- powerful movement commands
- find
- jump to specific location in a file (called a mark)
- folding (useful when you just want to see function stubbs)
To open your file in readonly mode use this:
vim -R <file name>
Here is a basic navigation guide:
j - move down one line
k - move up one line
h - left one char
l -right one char
ctrl-f - forward one page
ctrl-b - back one page
/<something> - search for something
n - next of whatever you searched for
N - next (search backwards) of whatever you searched for
:q - quit
:q! - quit without saving
:w - save
Here is a link for more information:
http://www.viemu.com/a_vi_vim_graphical_cheat_sheet_tutorial.html
Just to recap, if you will use unix vim is pretty fundamental. I have heard that learning vim is like learning to type. It is the next most useful tool you can learn for programming.
(Just to avoid editor wars you could also look into emacs or another editor, however I personally prefer vim)

I second this. Vim launches as fast as less, and many of the keyboard shortcuts (e.g., search, next page, previous page) are identical.

As others have said, you can use the power of vim. But importantly, you can do so without learning how to use vi/vim.
Vim comes with a less.vim
script that works pretty well as a replacement for less, with full color syntax highlighting. It uses less
keybindings (just hit 'q' to quit).
It had a few problems, so I improved it. I have a screenshot at http://huyz.us/2011/a-less-like-pager-with-color-syntax-highlighting/
2
Awesome! But as I couldn't find the script right away I'd like to share the command for locating it:find /usr/share/vim -name 'less.sh'
which is taken from this gist: gist.github.com/chauncey-garrett/9773770

I was also searching for this and found another solution using Vim:
http://ubuntu-tutorials.com/2008/07/14/use-vim-as-a-syntax-highlighting-pager/
The post is rather old, so now on more recent distros vim 7.2 is shipped and the .bashrc will read:
alias vless='vim -u /usr/share/vim/vim72/macros/less.vim'

MacVim comes with a shell script that you can use directly, located in: /Applications/MacVim.app/Contents/Resources/vim/runtime/macros/less.sh

I'm glad to announce a new package, e2ansi, that provides
syntax highlighting support for pagers like more
and less
.
The package use the mother of all text editors, Emacs, to
perform the actual syntax highlighting. As an added bonus, all other
conversions normally performed by Emacs -- like uncompressing files --
is also performed.
Example
The following is the result of viewing a file using less
and
e2ansi
:
Configuration
The package provides a command-line tool e2ansi-cat
that starts
Emacs in batch mode, opens files, syntax highlight them, and renders
the result using ANSI sequences.
You can integrate this into less
by setting the following variables
to, for example (the location of your init file may vary):
export "LESSOPEN=||-/usr/local/emacs --batch -Q -l ~/.emacs -l bin/e2ansi-cat %s"
export "LESS=-r"
alias "more=less -X -E"
In the configuration above, less
restores the original terminal
window content whereas more
simply output new content after the
prompt.
Note: If you use an old version of less
, it might not support the
||
or the -
syntax, in which case you may need to use simply
LESSOPEN=|/usr/local/emacs ...
.
Using less
in pipes
The "-" character in LESSOPEN
indicates that the input filter should
also be used when piping text into less
. In this case, Emacs can
only rely on text itself (and not a file name). Fortunately, Emacs
provides a system for this. In addition, the provided file file
e2ansi-magic.el
sets up additional file types. For example:
Why use Emacs?
- Emacs has support for virtually all programming languages and
structured text formats. In most cases, the syntax highlighting
support is excellent. - You can easily add support for more languages and formats, or modify
existing packages to suit you needs. - Emacs support color themes. When using
e2ansi
, the colors in the
theme is preserved when viewing a file inless
. You can pick a
suitable color theme from a number of sources, or design your own. - If you use Emacs as your editor of choice, you will get the same
highlighting in the editor as you get when viewing a file using
less
(minus limitations in ANSI sequence format and the terminal
window).
less
will take advantage of Emacs features that perform automatic
conversion, for example uncompressing files. In fact, you can teach
Emacs to perform any kind of conversion like automatically convert a
binary file to human readable form using an external tool.- You can view files located on other machines by using Emacs' syntax
for remote access like/USER@HOST:FILENAME
.
Useful links
e2ansi
is distributed on Melpa and can be installed using
the standard Emacs package system
e2ansi
is hosted on GitHub
- The
e2ansi
page on the Emacs Wiki
- The home of
less
.
Operating system notes
On MS Windows, the console does not natively support ANSI sequences.
Fortunately, theless
application is capable of rendering them. I
am not aware of any contemporary binary distribution ofless
for
MS Windows and the provided build files is hard to use. Fortunately,
it's easy to buildless
using CMake, see this text for
details.OS X distributes an ancient version of
less
. Fortunately, it's
easy to build a modern version directly from the source.
For OS X, I'd recommend using the package manager brew [brew.sh/] with brew dupes [github.com/Homebrew/homebrew-dupes] to install up-to-date versions of things likeless
.

If you have GNU Source-highlight installed you can use the following command to highlight the syntax of a single file:
$ src-hilite-lesspipe.sh yourfile.xml | less -R
Cansrc-hilite-lesspipe.sh
receive input via a pipe as well?

source-highlight
has a .sh
script located in /usr/share/source-highlight/*.sh
. I've created a symbolic link to it with name hcat
in /usr/bin
.
It shows highlighted output in terminal (console) – hcat
is highlighted cat.
How to:

Using OS X 10.9 (Maverick) this would do the trick:
- brew install source-highlight (Assuming brew is installed - http://brew.sh)
sudo nano /etc/launchd.conf
setenv LESSOPEN="| /usr/local/bin/src-hilite-lesspipe.sh %s"
setenv LESS=' -R '
(Add to /etc/launchd.conf)
reboot

In mac, you can just type view filename
, does similar thing like less.

With OSX,view filename
just launchesvim
by default - slightly different key bindings toless
(see other answers to this question for more details).

After installing GNU's source-highlight (package dev-util/source-highlight
on sabayon/gentoo), I configured those envs in /etc/bash/bashrc.d/my-less-src-highlight
:
#default: export LESSOPEN="|lesspipe %s"
#don't like: export LESSOPEN="| /usr/bin/src-hilite-lesspipe.sh %s"
#default: export LESS=" -R -M --shift 5"
export LESSCOLOR=always
export LESSCOLORIZER=/usr/bin/src-hilite-lesspipe.sh
I did not like to replace lesspipe
because that has other features. Concatenation did not work.

If you want the same syntax highlighting you use in Vim, but for some reason you prefer to use less
as your pager, you can use this script: https://github.com/rkitover/vimpager
The basic usage would be:
vimpager file.txt
or
vimcat file.ext | less -R
You can use -c
to pass extra commands which aren't in your .vimrc
(e.g. selecting a different colorscheme). The full command I use is:
vimcat -c 'set cmdheight=20' -c 'hi! clear Normal' -o - "$FILENAME" | less -REXS
Beware: If your Vim asks you to press Enter when it starts up, you won't see the prompt, but nothing will happen until you press Enter! The cmdheight
trick above can help to mitigate that.

I found highlight
which:
- Supports multiple colour schemes and 256-colours
- Works on STDIN (unlike
source-highlight
) - Is much faster than
pygmentize
Here is a script I call highlight-less-wrapper
which includes .bashrc
instructions on how to setup less
to use it automatically.
#!/bin/bash
# Have highlight read from STDIN if '-' is given as filename
# Setup - Add to .bashrc:
# LESSOPEN='|-highlight-less-wrapper "%s"'
# export LESS=-FMRXis
# Usage:
# $ less file
# OR
# $ pipeline | less
warn () { printf "%s: %sn" "$(basename "$0")" "$*" 1>&2; }
die () { warn "$@"; exit 1; }
# Argument checking
case $# in
0)
# Allow `exec $0` for less setup
echo "LESSOPEN='|-$(readlink -f "$0") "'"%s"''
exit 255 ;;
1)
# Only one argument is expected.
# less will invoke multiple times given multiple files.
file=$1
if [[ $file != - && ! -r $file ]]; then # less passes '-' for STDIN
die "Cannot open $file for reading"
fi ;;
*)
die "Expected only one argument" ;;
esac
# Run highlight
# highlight will read from STDIN when given a null filename
run_highlight () {
highlight --force -O truecolor --style aiseered "$1"
}
if [[ $file == - ]]; then # Run on stdin
run_highlight ""
else
run_highlight "$file"
fi
"Since Github is now part of Mordor Corp, the highlight Git repo moved" Was interested, but cmon it's not the 90's anymore devs need to grow up.

I had the same question and I landed hear, read all answers and the following is what I finally did to have syntax highlighting everytime I use less
or most
:
sudo apt install source-highlight
Then I went and created an alias for my less
and most
(I use ZSH, but you can add aliases for your .bashrc
file if you use bash):
vim ~/.zshrc
(For those who might get stuck in vim: press i to go to edit mode, when you are done press Esc then : then x and finally
Enter to save the changes)
And paste the following lines for debian-based distros (like Debian, Ubuntu, Mint, etc.):
alias most='AliasFuncLess() { unset -f AliasFuncLess; $(dpkg -L libsource-highlight-common | grep lesspipe) "$1" | less -R };AliasFuncLess'
alias most='AliasFuncMost() { unset -f AliasFuncMost; $(dpkg -L libsource-highlight-common | grep lesspipe) "$1" | most };AliasFuncMost'
or for RPM distros (Redhat, Fedora, Centos):
alias most='AliasFuncLess() { unset -f AliasFuncLess; $(rpm -ql source-highlight | grep lesspipe) "$1" | less -R };AliasFuncLess'
alias most='AliasFuncMost() { unset -f AliasFuncMost; $(rpm -ql source-highlight | grep lesspipe) "$1" | most };AliasFuncMost'
Remember to close the terminal and open it again to make sure alias is created.
Now you can enjoy the colors:
most yourFile.xml

I think that you should use a text editor. I like vim myself. That will give you LOTS of power when viewing files and then when you want to edit them you will already know the basics.
Here are some of the advantages of using a text editor (specifically vim):
- syntax-highlighting
- powerful movement commands
- find
- jump to specific location in a file (called a mark)
- folding (useful when you just want to see function stubbs)
To open your file in readonly mode use this:
vim -R <file name>
Here is a basic navigation guide:
j - move down one line
k - move up one line
h - left one char
l -right one char
ctrl-f - forward one page
ctrl-b - back one page
/<something> - search for something
n - next of whatever you searched for
N - next (search backwards) of whatever you searched for
:q - quit
:q! - quit without saving
:w - save
Here is a link for more information:
http://www.viemu.com/a_vi_vim_graphical_cheat_sheet_tutorial.html
Just to recap, if you will use unix vim is pretty fundamental. I have heard that learning vim is like learning to type. It is the next most useful tool you can learn for programming.
(Just to avoid editor wars you could also look into emacs or another editor, however I personally prefer vim)

I second this. Vim launches as fast as less, and many of the keyboard shortcuts (e.g., search, next page, previous page) are identical.

As others have said, you can use the power of vim. But importantly, you can do so without learning how to use vi/vim.
Vim comes with a less.vim
script that works pretty well as a replacement for less, with full color syntax highlighting. It uses less
keybindings (just hit 'q' to quit).
It had a few problems, so I improved it. I have a screenshot at http://huyz.us/2011/a-less-like-pager-with-color-syntax-highlighting/
2
Awesome! But as I couldn't find the script right away I'd like to share the command for locating it:find /usr/share/vim -name 'less.sh'
which is taken from this gist: gist.github.com/chauncey-garrett/9773770

The post is rather old, so now on more recent distros vim 7.2 is shipped and the .bashrc will read:

I'm glad to announce a new package, e2ansi, that provides
syntax highlighting support for pagers like more
and less
.
The package use the mother of all text editors, Emacs, to
perform the actual syntax highlighting. As an added bonus, all other
conversions normally performed by Emacs -- like uncompressing files --
is also performed.
Example
The following is the result of viewing a file using less
and
e2ansi
:
Configuration
The package provides a command-line tool e2ansi-cat
that starts
Emacs in batch mode, opens files, syntax highlight them, and renders
the result using ANSI sequences.
You can integrate this into less
by setting the following variables
to, for example (the location of your init file may vary):
export "LESSOPEN=||-/usr/local/emacs --batch -Q -l ~/.emacs -l bin/e2ansi-cat %s"
export "LESS=-r"
alias "more=less -X -E"
In the configuration above, less
restores the original terminal
window content whereas more
simply output new content after the
prompt.
Note: If you use an old version of less
, it might not support the
||
or the -
syntax, in which case you may need to use simply
LESSOPEN=|/usr/local/emacs ...
.
Using less
in pipes
The "-" character in LESSOPEN
indicates that the input filter should
also be used when piping text into less
. In this case, Emacs can
only rely on text itself (and not a file name). Fortunately, Emacs
provides a system for this. In addition, the provided file file
e2ansi-magic.el
sets up additional file types. For example:
Why use Emacs?
- Emacs has support for virtually all programming languages and
structured text formats. In most cases, the syntax highlighting
support is excellent. - You can easily add support for more languages and formats, or modify
existing packages to suit you needs. - Emacs support color themes. When using
e2ansi
, the colors in the
theme is preserved when viewing a file inless
. You can pick a
suitable color theme from a number of sources, or design your own. - If you use Emacs as your editor of choice, you will get the same
highlighting in the editor as you get when viewing a file using
less
(minus limitations in ANSI sequence format and the terminal
window).
less
will take advantage of Emacs features that perform automatic
conversion, for example uncompressing files. In fact, you can teach
Emacs to perform any kind of conversion like automatically convert a
binary file to human readable form using an external tool.- You can view files located on other machines by using Emacs' syntax
for remote access like/USER@HOST:FILENAME
.
Useful links
e2ansi
is distributed on Melpa and can be installed using
the standard Emacs package system
e2ansi
is hosted on GitHub
- The
e2ansi
page on the Emacs Wiki
- The home of
less
.
Operating system notes
On MS Windows, the console does not natively support ANSI sequences.
Fortunately, theless
application is capable of rendering them. I
am not aware of any contemporary binary distribution ofless
for
MS Windows and the provided build files is hard to use. Fortunately,
it's easy to buildless
using CMake, see this text for
details.OS X distributes an ancient version of
less
. Fortunately, it's
easy to build a modern version directly from the source.
For OS X, I'd recommend using the package manager brew [brew.sh/] with brew dupes [github.com/Homebrew/homebrew-dupes] to install up-to-date versions of things likeless
.

If you have GNU Source-highlight installed you can use the following command to highlight the syntax of a single file:
$ src-hilite-lesspipe.sh yourfile.xml | less -R
Cansrc-hilite-lesspipe.sh
receive input via a pipe as well?

Using OS X 10.9 (Maverick) this would do the trick:
- brew install source-highlight (Assuming brew is installed - http://brew.sh)
sudo nano /etc/launchd.conf
setenv LESSOPEN="| /usr/local/bin/src-hilite-lesspipe.sh %s"
setenv LESS=' -R '
(Add to /etc/launchd.conf)

In mac, you can just type view filename

view filename
just launches vim
by default - slightly different key bindings to less
(see other answers to this question for more details).– drevicko

After installing GNU's source-highlight (package dev-util/source-highlight
on sabayon/gentoo), I configured those envs in /etc/bash/bashrc.d/my-less-src-highlight
:
#default: export LESSOPEN="|lesspipe %s"
#don't like: export LESSOPEN="| /usr/bin/src-hilite-lesspipe.sh %s"
#default: export LESS=" -R -M --shift 5"
export LESSCOLOR=always
export LESSCOLORIZER=/usr/bin/src-hilite-lesspipe.sh
I did not like to replace lesspipe
because that has other features. Concatenation did not work.

If you want the same syntax highlighting you use in Vim, but for some reason you prefer to use less
as your pager, you can use this script: https://github.com/rkitover/vimpager
The basic usage would be:
vimpager file.txt
or
vimcat file.ext | less -R
You can use -c
to pass extra commands which aren't in your .vimrc
(e.g. selecting a different colorscheme). The full command I use is:
vimcat -c 'set cmdheight=20' -c 'hi! clear Normal' -o - "$FILENAME" | less -REXS
Beware: If your Vim asks you to press Enter when it starts up, you won't see the prompt, but nothing will happen until you press Enter! The cmdheight
trick above can help to mitigate that.

I found highlight
which:
- Supports multiple colour schemes and 256-colours
- Works on STDIN (unlike
source-highlight
) - Is much faster than
pygmentize
Here is a script I call highlight-less-wrapper
which includes .bashrc
instructions on how to setup less
to use it automatically.
#!/bin/bash
# Have highlight read from STDIN if '-' is given as filename
# Setup - Add to .bashrc:
# LESSOPEN='|-highlight-less-wrapper "%s"'
# export LESS=-FMRXis
# Usage:
# $ less file
# OR
# $ pipeline | less
warn () { printf "%s: %sn" "$(basename "$0")" "$*" 1>&2; }
die () { warn "$@"; exit 1; }
# Argument checking
case $# in
0)
# Allow `exec $0` for less setup
echo "LESSOPEN='|-$(readlink -f "$0") "'"%s"''
exit 255 ;;
1)
# Only one argument is expected.
# less will invoke multiple times given multiple files.
file=$1
if [[ $file != - && ! -r $file ]]; then # less passes '-' for STDIN
die "Cannot open $file for reading"
fi ;;
*)
die "Expected only one argument" ;;
esac
# Run highlight
# highlight will read from STDIN when given a null filename
run_highlight () {
highlight --force -O truecolor --style aiseered "$1"
}
if [[ $file == - ]]; then # Run on stdin
run_highlight ""
else
run_highlight "$file"
fi
"Since Github is now part of Mordor Corp, the highlight Git repo moved" Was interested, but cmon it's not the 90's anymore devs need to grow up.

I had the same question and I landed hear, read all answers and the following is what I finally did to have syntax highlighting everytime I use less
or most
:
sudo apt install source-highlight
Then I went and created an alias for my less
and most
(I use ZSH, but you can add aliases for your .bashrc
file if you use bash):
vim ~/.zshrc
(For those who might get stuck in vim: press i to go to edit mode, when you are done press Esc then : then x and finally
Enter to save the changes)
And paste the following lines for debian-based distros (like Debian, Ubuntu, Mint, etc.):
alias most='AliasFuncLess() { unset -f AliasFuncLess; $(dpkg -L libsource-highlight-common | grep lesspipe) "$1" | less -R };AliasFuncLess'
alias most='AliasFuncMost() { unset -f AliasFuncMost; $(dpkg -L libsource-highlight-common | grep lesspipe) "$1" | most };AliasFuncMost'
or for RPM distros (Redhat, Fedora, Centos):
alias most='AliasFuncLess() { unset -f AliasFuncLess; $(rpm -ql source-highlight | grep lesspipe) "$1" | less -R };AliasFuncLess'
alias most='AliasFuncMost() { unset -f AliasFuncMost; $(rpm -ql source-highlight | grep lesspipe) "$1" | most };AliasFuncMost'
Remember to close the terminal and open it again to make sure alias is created.
Now you can enjoy the colors:
