# 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.

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][]
|
||||
|
||||
|
||||

# * syscall_${GOOS}.go
|
||||
#
|
||||
# This hand-written Go file implements system calls that need
|
||||
# special handling and lists "//sys" comments giving prototypes
|
||||
# for ones that can be auto-generated. Mksyscall reads those
|
||||
# comments to generate the stubs.

#
|

# * syscall_${GOOS}_${GOARCH}.go
|

#
|

# Same as syscall_${GOOS}.go except that it contains code specific
|
||||
# to ${GOOS} on one particular architecture.
|
||||
#
|
||||
# * types_${GOOS}.c
|
||||
#
|
||||
# This hand-written C file includes standard C headers and then
|
||||
# creates typedef or enum names beginning with a dollar sign
|
||||
# (use of $ in variable names is a gcc extension). The hardest
|
||||
# part about preparing this file is figuring out which headers to
|
||||
# include and which symbols need to be #defined to get the
|
||||
# actual data structures that pass through to the kernel system calls.
|
||||
# Some C libraries present 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.c and types_linux.c for examples.
|
||||
#
|
||||
# * zerror_${GOOS}_${GOARCH}.go
|
||||
#
|
||||
# This machine-generated file defines the system's error numbers,
|
||||
# error strings, and signal numbers. The generator is "mkerrors.sh".
|
||||
# Usually no arguments are needed, but mkerrors.sh will pass its
|
||||
# arguments on to godefs.

# 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`
|
||||
|
||||
A file containing all the generated syscalls for a specific GOOS and GOARCH.
|
||||
Generated by `mksyscall.go` (see above).
|
||||
|
||||
### `zsysnum_${GOOS}_${GOARCH}.go`
|
||||
|
||||
A list of numeric constants for all the syscall number of the specific GOOS
|
||||
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).
