+
+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, caste, color, religion, or sexual
+identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the overall
+  community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or advances of
+  any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email address,
+  without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+https://github.com/guptarohit.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of
+actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or permanent
+ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the
+community.
+
+## Attribution
+

+
+Go package to make lightweight ASCII line graphs ╭┈╯.
+
+![image][]
+
+## Installation
+```bash
+go get -u github.com/guptarohit/asciigraph@latest
+```
+
+## Usage
+
+### Basic graph
+
+```go
+package main
+
+import (
+    "fmt"
+    "github.com/guptarohit/asciigraph"
+)
+
+func main() {
+    data := []float64{3, 4, 9, 6, 2, 4, 5, 8, 5, 10, 2, 7, 2, 5, 6}
+    graph := asciigraph.Plot(data)
+
+    fmt.Println(graph)
+}
+```
+
+Running this example would render the following graph:
+```bash
+  10.00 ┤        ╭╮
+   9.00 ┤ ╭╮     ││
+   8.00 ┤ ││   ╭╮││
+   7.00 ┤ ││   ││││╭╮
+   6.00 ┤ │╰╮  ││││││ ╭
+   5.00 ┤ │ │ ╭╯╰╯│││╭╯
+   4.00 ┤╭╯ │╭╯   ││││
+   3.00 ┼╯  ││    ││││
+   2.00 ┤   ╰╯    ╰╯╰╯
+```
+
+### Multiple Series
+
+```go
+package main
+
+import (
+    "fmt"
+    "github.com/guptarohit/asciigraph"
+)
+
+func main() {
+	data := [][]float64{{0, 1, 2, 3, 3, 3, 2, 0}, {5, 4, 2, 1, 4, 6, 6}}
+	graph := asciigraph.PlotMany(data)
+
+	fmt.Println(graph)
+}
+```
+
+Running this example would render the following graph:
+```bash
+ 6.00 ┤    ╭─
+ 5.00 ┼╮   │
+ 4.00 ┤╰╮ ╭╯
+ 3.00 ┤ │╭│─╮
+ 2.00 ┤ ╰╮│ ╰╮
+ 1.00 ┤╭╯╰╯  │
+ 0.00 ┼╯     ╰
+```
+
+### Colored graphs
+
+```go
+package main
+
+import (
+    "fmt"
+    "github.com/guptarohit/asciigraph"
+)
+
+func main() {
+	data := make([][]float64, 4)
+
+	for i := 0; i < 4; i++ {
+		for x := -20; x <= 20; x++ {
+			v := math.NaN()
+			if r := 20 - i; x >= -r && x <= r {
+				v = math.Sqrt(math.Pow(float64(r), 2)-math.Pow(float64(x), 2)) / 2
+			}
+			data[i] = append(data[i], v)
+		}
+	}
+	graph := asciigraph.PlotMany(data, asciigraph.Precision(0), asciigraph.SeriesColors(
+		asciigraph.Red,
+		asciigraph.Yellow,
+		asciigraph.Green,
+		asciigraph.Blue,
+	))
+
+	fmt.Println(graph)
+}
+```
+
+Running this example would render the following graph:
+
+![colored_graph_image][]
+
+### Legends for colored graphs
+
+The graph can include legends for each series, making it easier to interpret.
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/guptarohit/asciigraph"
+	"math"
+)
+
+func main() {
+	data := make([][]float64, 3)
+	for i := 0; i < 3; i++ {
+		for x := -12; x <= 12; x++ {
+			v := math.NaN()
+			if r := 12 - i; x >= -r && x <= r {
+				v = math.Sqrt(math.Pow(float64(r), 2)-math.Pow(float64(x), 2)) / 2
+			}
+			data[i] = append(data[i], v)
+		}
+	}
+	graph := asciigraph.PlotMany(data,
+		asciigraph.Precision(0),
+		asciigraph.SeriesColors(asciigraph.Red, asciigraph.Green, asciigraph.Blue),
+		asciigraph.SeriesLegends("Red", "Green", "Blue"),
+		asciigraph.Caption("Series with legends"))
+	fmt.Println(graph)
+}
+```
+Running this example would render the following graph:
+
+![graph_with_legends_image][]
+
+
+## CLI Installation
+
+This package also brings a small utility for command line usage.
+
+Assuming `$GOPATH/bin` is in your `$PATH`, install CLI with following command:
+```bash
+go install github.com/guptarohit/asciigraph/cmd/asciigraph@latest
+```
+
+or pull Docker image:
+```bash
+docker pull ghcr.io/guptarohit/asciigraph:latest
+```
+
+or download binaries from the [releases][] page.
+
+
+## CLI Usage
+
+```bash                                                                                                                ✘ 0|125  16:19:23

+asciigraph expects data points from stdin. Invalid values are logged to stderr.
+```
+
+
+Feed it data points via stdin:
+```bash
+seq 1 72 | asciigraph -h 10 -c "plot data from stdin"
+```
+
+or use Docker image:
+```bash
+seq 1 72 | docker run -i --rm ghcr.io/guptarohit/asciigraph -h 10 -c "plot data from stdin"
+```

+# Building `sys/unix`
+
+The sys/unix package provides access to the raw system call interface of the
+underlying operating system. See: https://godoc.org/golang.org/x/sys/unix
+
+Porting Go to a new architecture/OS combination or adding syscalls, types, or
+constants to an existing architecture/OS pair requires some manual effort;
+however, there are tools that automate much of the process.
+
+## Build Systems
+
+There are currently two ways we generate the necessary files. We are currently
+migrating the build system to use containers so the builds are reproducible.
+This is being done on an OS-by-OS basis. Please update this documentation as
+components of the build system change.
+
+### Old Build System (currently for `GOOS != "linux"`)
+
+The old build system generates the Go files based on the C header files
+present on your system. This means that files
+for a given GOOS/GOARCH pair must be generated on a system with that OS and
+architecture. This also means that the generated code can differ from system
+to system, based on differences in the header files.
+
+To avoid this, if you are using the old build system, only generate the Go
+files on an installation with unmodified header files. It is also important to
+keep track of which version of the OS the files were generated from (ex.
+Darwin 14 vs Darwin 15). This makes it easier to track the progress of changes
+and have each OS upgrade correspond to a single change.
+
+To build the files for your current OS and architecture, make sure GOOS and
+GOARCH are set correctly and run `mkall.sh`. This will generate the files for
+your specific system. Running `mkall.sh -n` shows the commands that will be run.
+
+Requirements: bash, go
+
+### New Build System (currently for `GOOS == "linux"`)
+
+The new build system uses a Docker container to generate the go files directly
+from source checkouts of the kernel and various system libraries. This means
+that on any platform that supports Docker, all the files using the new build
+system can be generated at once, and generated files will not change based on
+what the person running the scripts has installed on their computer.
+
+The OS specific files for the new build system are located in the `${GOOS}`
+directory, and the build is coordinated by the `${GOOS}/mkall.go` program. When
+the kernel or system library updates, modify the Dockerfile at
+`${GOOS}/Dockerfile` to checkout the new release of the source.
+
+To build all the files under the new build system, you must be on an amd64/Linux
+system and have your GOOS and GOARCH set accordingly. Running `mkall.sh` will
+then generate all of the files for all of the GOOS/GOARCH pairs in the new build
+system. Running `mkall.sh -n` shows the commands that will be run.
+
+Requirements: bash, go, docker
+
+## Component files
+
+This section describes the various files used in the code generation process.
+It also contains instructions on how to modify these files to add a new
+architecture/OS or to add additional syscalls, types, or constants. Note that
+if you are using the new build system, the scripts/programs cannot be called normally.
+They must be called from within the docker container.
+
+### asm files
+
+The hand-written assembly file at `asm_${GOOS}_${GOARCH}.s` implements system
+call dispatch. There are three entry points:
+```
+  func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
+  func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr)
+  func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
+```
+The first and second are the standard ones; they differ only in how many
+arguments can be passed to the kernel. The third is for low-level use by the
+ForkExec wrapper. Unlike the first two, it does not call into the scheduler to
+let it know that a system call is running.
+
+When porting Go to a new architecture/OS, this file must be implemented for
+each GOOS/GOARCH pair.
+
+### mksysnum
+
+Mksysnum is a Go program located at `${GOOS}/mksysnum.go` (or `mksysnum_${GOOS}.go`
+for the old system). This program takes in a list of header files containing the
+syscall number declarations and parses them to produce the corresponding list of
+Go numeric constants. See `zsysnum_${GOOS}_${GOARCH}.go` for the generated
+constants.
+
+Adding new syscall numbers is mostly done by running the build on a sufficiently
+new installation of the target OS (or updating the source checkouts for the
+new build system). However, depending on the OS, you may need to update the
+parsing in mksysnum.
+
+### mksyscall.go
+
+The `syscall.go`, `syscall_${GOOS}.go`, `syscall_${GOOS}_${GOARCH}.go` are
+hand-written Go files which implement system calls (for unix, the specific OS,
+or the specific OS/Architecture pair respectively) that need special handling
+and list `//sys` comments giving prototypes for ones that can be generated.
+
+The mksyscall.go program takes the `//sys` and `//sysnb` comments and converts
+them into syscalls. This requires the name of the prototype in the comment to
+match a syscall number in the `zsysnum_${GOOS}_${GOARCH}.go` file. The function
+prototype can be exported (capitalized) or not.
+
+Adding a new syscall often just requires adding a new `//sys` function prototype
+with the desired arguments and a capitalized name so it is exported. However, if
+you want the interface to the syscall to be different, often one will make an
+unexported `//sys` prototype, and then write a custom wrapper in
+`syscall_${GOOS}.go`.
+
+### types files
+
+For each OS, there is a hand-written Go file at `${GOOS}/types.go` (or
+`types_${GOOS}.go` on the old system). This file includes standard C headers and
+creates Go type aliases to the corresponding C types. The file is then fed
+through godef to get the Go compatible definitions. Finally, the generated code
+is fed though mkpost.go to format the code correctly and remove any hidden or
+private identifiers. This cleaned-up code is written to
+`ztypes_${GOOS}_${GOARCH}.go`.
+
+The hardest part about preparing this file is figuring out which headers to
+include and which symbols need to be `#define`d to get the actual data
+structures that pass through to the kernel system calls. Some C libraries
+preset alternate versions for binary compatibility and translate them on the
+way in and out of system calls, but there is almost always a `#define` that can
+get the real ones.
+See `types_darwin.go` and `linux/types.go` for examples.
+
+To add a new type, add in the necessary include statement at the top of the
+file (if it is not already there) and add in a type alias line. Note that if
+your type is significantly different on different architectures, you may need
+some `#if/#elif` macros in your include statements.
+
+### mkerrors.sh
+
+This script is used to generate the system's various constants. This doesn't
+just include the error numbers and error strings, but also the signal numbers
+and a wide variety of miscellaneous constants. The constants come from the list
+of include files in the `includes_${uname}` variable. A regex then picks out
+the desired `#define` statements, and generates the corresponding Go constants.
+The error numbers and strings are generated from `#include <errno.h>`, and the
+signal numbers and strings are generated from `#include <signal.h>`. All of
+these constants are written to `zerrors_${GOOS}_${GOARCH}.go` via a C program,
+`_errors.c`, which prints out all the constants.
+
+To add a constant, add the header that includes it to the appropriate variable.
+Then, edit the regex (if necessary) to match the desired constant. Avoid making
+the regex too broad to avoid matching unintended constants.
+
+### internal/mkmerge
+
+This program is used to extract duplicate const, func, and type declarations
+from the generated architecture-specific files listed below, and merge these
+into a common file for each OS.
+
+The merge is performed in the following steps:
+1. Construct the set of common code that is identical in all architecture-specific files.
+2. Write this common code to the merged file.
+3. Remove the common code from all architecture-specific files.
+
+
+## Generated files
+
+### `zerrors_${GOOS}_${GOARCH}.go`
+
+A file containing all of the system's generated error numbers, error strings,
+signal numbers, and constants. Generated by `mkerrors.sh` (see above).
+
+### `zsyscall_${GOOS}_${GOARCH}.go`

+Generated by `mksyscall.go` (see above).
+
+### `zsysnum_${GOOS}_${GOARCH}.go`
+

+and GOARCH. Generated by mksysnum (see above).
+
+### `ztypes_${GOOS}_${GOARCH}.go`
+
+A file containing Go types for passing into (or returning from) syscalls.
+Generated by godefs and the types file (see above).
