Contributing Guide
==================
Thank you so much for taking the time to contribute in to htop!
Bug Reports
-----------
Bug reports should be posted in the [Github issue
tracker](https://github.com/htop-dev/htop/issues).
Bug reports are extremely important since it's impossible for us to test
htop in every possible system, distribution and scenario. Your feedback
is what keeps the tool stable and always improving! Thank you!
Pull Requests
-------------
Code contributions are most welcome! Just [fork the
repo](https://github.com/htop-dev/htop) and send a [pull
request](https://github.com/htop-dev/htop/pulls). Help is especially
appreciated for support of platforms other than Linux. If proposing new
features, please be mindful that htop is a system tool that needs to keep a
small footprint and perform well on systems under stress -- so unfortunately
we can't accept every new feature proposed, as we need to keep the tool slim
and maintainable. Great ideas backed by a PR are always carefully considered
for inclusion though! Also, PRs containing bug fixes and portability tweaks
are always included, please send those in!
Feature Requests
----------------
Please label Github issues that are feature requests with the [`feature
request`](https://github.com/htop-dev/htop/issues?utf8=%E2%9C%93&q=is%3Aissue+label%3A%22feature+request%22+)
label.
Style Guide
-----------
To make working with the code easier a set of guidelines have evolved in
the past that new contributions should try to follow. While they are not set
in stone and always up for changes should the need arise they still provide
a first orientation to go by when contributing to this repository.
The details of the coding style as well as what to take care about with your
contributions can be found in our [style guide](docs/styleguide.md).

Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002 Free Software
Foundation, Inc.
This file is free documentation; the Free Software Foundation gives
unlimited permission to copy, distribute and modify it.
Basic Installation
==================
These are generic installation instructions.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. (Caching is
disabled by default to prevent problems with accidental use of stale
cache files.)
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You only need
`configure.ac' if you want to change it or regenerate `configure' using
a newer version of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
Running `configure' takes awhile. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the `configure' script does not know about. Run `./configure --help'
for details on some of the pertinent environment variables.
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
If you have to use a `make' that does not support the `VPATH'
variable, you have to compile the package for one architecture at a
time in the source code directory. After you have installed the
package for one architecture, use `make distclean' before reconfiguring
for another architecture.
Installation Names
==================
By default, `make install' will install the package's files in
`/usr/local/bin', `/usr/local/man', etc. You can specify an
installation prefix other than `/usr/local' by giving `configure' the
option `--prefix=PATH'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
give `configure' the option `--exec-prefix=PATH', the package will use
PATH as the prefix for installing programs and libraries.
Documentation and other data files will still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=PATH' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' cannot figure out
automatically, but needs to determine by the type of machine the package
will run on. Usually, assuming the package is built to be run on the
_same_ architectures, `configure' can figure that out, but if it prints
a message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the `--target=TYPE' option to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share,
you can create a site shell script called `config.site' that gives
default values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to `configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
will cause the specified gcc to be used as the C compiler (unless it is
overridden in the site shell script).
`configure' Invocation
======================
`configure' recognizes the following options to control how it
operates.
`--help'
`-h'
Print a summary of the options to `configure', and exit.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

## Introduction
Introduction
~~~~~~~~~~~~
`htop` is a cross-platform interactive process viewer.
This is htop, an interactive process viewer.
It requires ncurses. It is tested with Linux 2.6,
but is also reported to work (and was originally developed)
with the 2.4 series.
`htop` allows scrolling the list of processes vertically and horizontally to see their full command lines and related information like memory and CPU consumption.
Note that, while, htop is Linux specific -- it is based
on the Linux /proc filesystem -- it is also reported to work
with FreeBSD systems featuring a Linux-compatible /proc.
The information displayed is configurable through a graphical setup and can be sorted and filtered interactively.
This software has evolved considerably during the last months,
and is reasonably complete, but there is still room for
improvement. Read the TODO file to see what's known to be missing.
Tasks related to processes (e.g. killing and renicing) can be done without entering their PIDs.
Comparison between 'htop' and 'top'
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Running `htop` requires `ncurses` libraries (typically named libncursesw*).
* In 'htop' you can scroll the list vertically and horizontally
to see all processes and full command lines.
* In 'top' you are subject to a delay for each unassigned
key you press (especially annoying when multi-key escape
sequences are triggered by accident).
* 'htop' starts faster ('top' seems to collect data for a while
before displaying anything).
* In 'htop' you don't need to type the process number to
kill a process, in 'top' you do.
* In 'htop' you don't need to type the process number or
the priority value to renice a process, in 'top' you do.
* In 'htop' you can kill multiple processes at once.
* 'top' is older, hence, more tested.
For more information and details on how to contribute to `htop` visit [htop.dev](https://htop.dev).
Compilation instructions
~~~~~~~~~~~~~~~~~~~~~~~~
## Build instructions
This program is distributed as a standard autotools-based package.
See the INSTALL file for detailed instructions, but you are
probably used to the common "configure/make/make install" routine.
This program is distributed as a standard GNU autotools-based package.
See the manual page (man htop) or the on-line help ('F1' or 'h'
inside htop) for a list of supported key commands.
Compiling `htop` requires the header files for `ncurses` (libncursesw*-dev). Install these and other required packages for C development from your package manager.
Then, when compiling from a [release tarball](https://bintray.com/htop/source/htop), run:
~~~ shell
./configure && make
~~~
Alternatively, for compiling sources downloaded from the Git repository (`git clone` or downloads from [Github releases](https://github.com/htop-dev/htop/releases/)),
install the header files for `ncurses` (libncursesw*-dev) and other required development packages from your distribution's package manager. Then run:
~~~ shell
./autogen.sh && ./configure && make
~~~
By default `make install` will install into `/usr/local`, for changing the path use `./configure --prefix=/some/path`.
See the manual page (`man htop`) or the on-line help ('F1' or 'h' inside `htop`) for a list of supported key commands.
## Support
If you have trouble running `htop` please consult your Operating System / Linux distribution documentation for getting support and filing bugs.
## Bugs, development feedback
We have a [development mailing list](https://htop.dev/mailinglist.html). Feel free to subscribe for release announcements or asking questions on the development of htop.
You can also join our IRC channel #htop on freenode and talk to the developers there.
If you have found an issue with the source of htop, please check whether this has already been reported in our [Github issue tracker](https://github.com/htop-dev/htop/issues).
If not, please file a new issue describing the problem you have found, the location in the source code you are referring to and a possible fix.
## History
`htop` was invented, developed and maintained by Hisham Muhammad from 2004 to 2019. His [legacy repository](https://github.com/hishamhm/htop/) has been archived to preserve the history.
In 2020 a [team](https://github.com/orgs/htop-dev/people) took over the development amicably and continues to maintain `htop` collaboratively.
