Build Files
Format
AdvMake uses Starlark as the format for its build files. -Modules are also defined for both convenience and extra functionality.
Starlark is a Python-like language meant for configuration files.
Configuration
Build files are by default called AdvMakefile, but that can be set via -f
An AdvMakefile example can be found at AdvMake’s repo as it uses AdvMake itself.
AdvMake runs functions exposed by starlark in the format <name>_<target>.
-To set the default name and target, the global variables defaultName, and defaultTarget must be set.
-Here is an example from AdvMake’s AdvMakefile:
defaultName = "advmake"
-defaultTarget = "build"
-This will tell AdvMake to run the function advmake_build() when run with no arguments.
If AdvMake is run with one argument (such as advmake install), it will use the default name with the specified target,
-so in that case, it would run advmake_install().
If run with two arguments, AdvMake will use the first argument as the name and the second as the target.
-So, running advmake hello world would run the function hello_world().
Modules
As previously mentioned, AdvMake comes with modules. Those are as follows:
runtime
The runtime module exposes some of golang’s runtime methods and variables.
runtime.GOOS
Stores a string denoting the operating system being used.
-Godocruntime.GOARCH
Stores a string denoting the CPU architecture being used.
-Godocruntime.NumCPU()
Get the number of logical CPUs available to the current process
-Godocruntime.GOMAXPROCS()
Definition: runtime.GOMAXPROCS(n)
Get or set the value of the GOMAXPROCS environment variable. This variable controls the maximum number of CPUs that can execute. This function will set GOMAXPROCS to n and then return the previous value. If n<1, this function will not set the variable and will instead return the current setting
encoding
The strings module contains functions for encoding and decoding various formats. This module contains submodules for the various formats
Available submodules:
JsonYamlTomlHex
encoding.<Submodule>.Load()
Load a string formatted as the submodule format into a dictionary or string.
Examples:
x = encoding.Json.Load('{"encoding": "json"}')
-# x["encoding"] == "json"
-y = encoding.Hex.Load('546573740a')
-# y == "Test"
-encoding.<Submodule>.Dump()
Dump a string formatted as the submodule format from a dictionary or string
Examples:
xDict = {"encoding": {"type": "toml"}}
-x = encoding.Toml.Dump(xDict)
-# x == '''
-#
-# [encoding]
-# type = "toml"
-#
-# '''
-y = encoding.Hex.Dump("Test")
-# y = "546573740a"
-file
The file module contains functions for manipulation and checking of files
file.Expand()
Definition: file.Expand(file, mappings)
Expand any instances of $VAR in a file according to provided mappings.
Examples:
file.txt before:
I am running on $OS and architecture $arch
-Code:
file.Expand("file.txt", {"OS": runtime.GOOS, "arch": runtime.GOARCH})
-file.txt after:
I am running on linux and architecture x86_64
-file.Exists()
Definition: file.Exists(filepath)
Check whether a file exists
Example:
file.Exists("/etc/fstab") # True
-file.Content()
Definition: file.Content(filepath)
Returns contents of a file as a string
Example:
file.txt:
This is a file
-Code:
file.Content("file.txt") # "This is a file"
-strings
The strings module contains functions for the manipulation of strings
strings.Regex()
Definition: strings.Regex(string, pattern, regex)
Parse a string using a regular expression and return the result in the specified format.
Examples:
x = strings.Regex("Hello, World", "$2, $1", "(.+), (.+)")
-# x == "World, Hello"
-y = strings.Regex("Hello, World", "$y, $x", "(?P<x>.+), (?P<y>.+)")
-# y == "World, Hello"
-z = strings.Regex("Hello, World", "$match, $2, $1", "(.+), (.+)")
-# z == "Hello, World, World, Hello"
-strings.HasSuffix()
Definition: strings.HasSuffix(string, suffix)
Check whether a string ends with a suffix.
Examples:
strings.HasSuffix("doc.pdf", ".pdf") # True
-strings.HasSuffix("doc.pdf", ".md") # False
-strings.HasPrefix()
Definition: strings.HasPrefix(string, prefix)
Check whether a string starts with a prefix.
Example:
strings.HasPrefix("doc.pdf", "doc") # True
-strings.TrimSuffix()
Definition: strings.HasSuffix(string, suffix)
Remove suffix from string if it exists. If it does not exist, the string is returned unchanged.
Example:
strings.TrimSuffix("doc.pdf", ".pdf") # "doc"
-strings.TrimPrefix()
Definition: strings.TrimPrefix(string, prefix)
Remove prefix from string if it exists. If it does not exist, the string is returned unchanged.
Example:
strings.TrimPrefix("doc.pdf", "doc") # ".pdf"
-strings.TrimSpace()
Definition: strings.TrimSpace(string)
Trim leading and trailing white space, as defined by Unicode
Example:
strings.TrimSpace(" Hi ") # "Hi"
-input
The input module prompts the user for input
input.Prompt()
Definition: input.Prompt(prompt)
Print prompt and wait for input, returning on newline
Example:
input.Prompt("Enter number: ")
-input.Choice()
Definition: input.Choice(prompt, choices)
Assign number to each choice and prompt user to choose one
Example:
input.Choice("Choose greeting", ["Hi", "Hello", "Good morning"])
-The above example looks like this to the user:
[1] "Hi"
-[2] "Hello"
-[3] "Good Morning"
-Choose greeting:
-When the user chooses a number, the function will return the associated string. So, if the user chooses 1, "Hi" will be returned.
url
The url module contains functions for the manipulation of URLs
url.Parse()
Definition: url.Parse(urlString)
Parses a URL and returns its components
Example:
parsed = url.Parse("https://www.arsenm.dev/docs/advmake/build-files")
-# parsed.Scheme == "https"
-# parsed.Host == "www.arsenm.dev"
-# parsed.Path == "/docs/advmake/build-files"
-shell
The shell module contains functions for accessing and utilizing the shell.
shell.Exec()
Definition: shell.Exec(command, output?, concurrent?)
Runs a command or script using sh -c, sending the output to STDOUT and returning it unless set otherwise. It can also be concurrent.
Examples:
Code:
x = shell.Exec("date +%r") # "12:00:00 AM"
-y = shell.Exec("date +%r", output='return') # "12:00:00 AM"
-z = shell.Exec("date +%r | base64", output='stdout') # None
-shell.Exec("""
- sleep 1
- sleep 2
-""", concurrent=True) # Sleeps for two seconds
-STDOUT:
12:00:00 AM
-MTI6MDA6MDAgQU0K
-shell.Getenv()
Definition: shell.Getenv(key)
Returns the value of an environment variable
Example:
shell.Getenv('TERM') # "xterm"
-shell.Setenv()
Definition: shell.Setenv(key, value, onlyIfUnset?)
Sets the value of an environment variable. It can be configured not to set the value if it is already set
Examples:
shell.Setenv("X", "x") # $X = x
-shell.Setenv("CC", "gcc") # if $CC unset, $CC = gcc
-shell.LookPath()
Definition: shell.LookPath(command)
Returns the path to the executable of the specified command. Returns -1 if the command is not found in PATH.
Examples:
shell.LookPath('sh') # "/bin/sh"
-shell.LookPath('nonExistentCommand') # -1
-net
The net module contains various network functions
net.Download()
Download a file from a URL, optionally specifying the filename. It will show progress if the Content-Length header is present.
Examples:
net.Download("https://minio.arsenm.dev/advmake/0.0.1/advmake-linux-x86_64")
