Usage

Generate

The cli executes commands and generate files and directories based on configuration file

## progen.yml

# list directories to creation
dirs:
  - x/y

# list files to creation
files:
  - path: x/some_file.txt
    data: |
      some data

# list commands to execution 
cmd:
  - touch second_file.txt
  - tree

Execution

All actions execute in declared order. Base actions (dir, files,cmd) could be configured with <unique_suffix> to separate action execution.

## progen.yml

dirs1:
  - api/some_project/v1
cmd1:
  - chmod -R 777 api
dirs2:
  - api/some_project_2/v1
cmd2:
  - chmod -R 777 api

Templates

Configuration preprocessing uses text/template of golang's stdlib. Using templates could be useful to avoiding duplication in configuration file. All text/template variables must be declared as comments and can be used only to configure data of configuration file (all ones skipping for file.data section). Configuration's yaml tag tree also use as text/template variables dictionary and can be use for avoiding duplication in configuration file and files contents (files section).

## progen.yml

## `text/template` variables declaration 👇
# {{$project_name := "SOME_PROJECT"}}

## unmapped section (not `dirs`, `files`, `cmd`, `http`) can be use as template variables
vars:
  file_path: some/file/path

dirs:
  - api/{{$project_name}}/v1 # used from `text/template` variables
  - internal/{{.vars.file_path}} # used from `vars` section
  - pkg/{{printf `%s-%s` $project_name `data`}}

files:
  - path: internal/{{$project_name}}.txt
    data: |
      Project name:{{$project_name}}
  - path: pkg/{{printf `%s-%s` $project_name `data`}}/some_file.txt
    data: |
      {{$project_name}}

cmd:
  - "cat internal/{{$project_name}}.txt"
  - exec: ls
    dir: .
    args: [ -l ]

Custom template functions

Function	args	Description
`random`
`random.Alpha`	length `int`	Generates a random alphabetical `(A-Z, a-z)` string of a desired length.
`random.Num`	length `int`	Generates a random numeric `(0-9)` string of a desired length.
`random.AlphaNum`	length `int`	Generates a random alphanumeric `(0-9, A-Z, a-z)` string of a desired length.
`random.ASCII`	length `int`	Generates a random string of a desired length, containing the set of printable characters from the 7-bit ASCII set. This includes space (’ ‘), but no other whitespace character.
`slice`
`slice.New`	N `any` elements	Create new slice from any numbers of elements (`{ $element := slice.New "a" 1 "b" }}`)
`slice.Append`	slice, N `any` elements	Add element to exists slice (`{{ $element := slice.Append $element "b"}}`)
`strings`
`strings.Replace`	s, old, new string, n int	Replace returns a copy of the string `s` with `old` replaced by `new` (work the same as `strings.Replace` from `stdlib`).

Custom template's functions added as custom arguments to the template function map.

Flags

Configuration file

By default progen try to find progen.yml file for execution. -f flag specify custom configuration file location:

progen -f custom_conf.yaml

Instead of specifying a config file, you can pass a single configuration file in the pipe the file in via STDIN. To pipe a progen.yml from STDIN:

progen - < progen.yml

or

cat progen.yml | progen -

If you use STDIN the system ignores any -f option.

Example (get progen.yml from gitlab repository with replacing text/template variables using -tvar flag):

curl -H PRIVATE-TOKEN:token https://gitlab.some.com/api/v4/projects/13/repository/files/shared%2Fteplates%2Fsimple%2Fprogen.yml/raw\?ref\=feature/templates | progen -v -dr -tvar=.vars.GOPROXY=some_proxy -

Print error stack trace

To print a stack trace of the error which occurred during execution of the cli, use -errtrace flag:

% progen -f ../not_exists_config.yml
2023-03-04 15:05:54	FATAL	read config: config file:
    github.com/kozmod/progen/internal/config.(*Reader).Read
        /Users/some_user/projects/progen/internal/config/reader.go:39
  - open ../not_exists_config.yml: no such file or directory

Dry Run mode

The -dr flag uses to execute configuration in dry run mod. All action will be executed without applying.

## progen.yml

# {{$project_name := "SOME_PROJECT"}}
dirs:
  - api/{{ $project_name }}/v1 # apply template variables, but not create directories on 'dry run'
cmd:
  - tree # not execute on 'dry run' mode

files:
  - path: api/v1/some_file.txt # apply template variables and only printing the file's data
    data: |
      some file data data fot project: {{ $project_name }}

% progen -v -dr

2023-03-07 07:57:52	INFO	execution time: 3.69506ms

Application working directory

The -awd flag uses for setting application working directory. All paths declared in the config file are calculated considering the root directory.

Print configuration file

To print the configuration file after processing as text/template, use -printconf flag:

## progen.yml

vars:
  some_data: VARS_SOME_DATA

# {{- $var_1 := random.AlphaNum 15}}
#  {{- $var_2 := "echo some_%s"}}
cmd:
  - echo {{ $var_1 }}
  - "{{ printf $var_2  `value` }}"
  - echo {{ .vars.some_data }}

% progen -printconf
2023-03-04 14:57:43	INFO	preprocessed config:
vars:
  some_data: VARS_SOME_DATA

#
#
cmd:
  - echo AHNsgyzVxRqeqLt
  - "echo some_value"
  - echo VARS_SOME_DATA

Files preprocessing

By default, all files loading to the memory and process as text/template before saving to a file system. To change this behavior, set -pf=false.

% progen -v -dr -f progen.yml
2023-02-05 14:15:54	INFO	application working directory: /Users/user_1/GoProjects/service

Template variables

Any part of template variable tree can be overrides using -tvar flag

## progen.yml

## `text/template` variables declaration 👇
# {{$project_name := "SOME_PROJECT"}}

## unmapped section (not `dirs`, `files`, `cmd`, `http`) can be use as template variables
vars:
  file_path: some/file/path
  file_path_2: some/file/path_2

dirs:
  - api/{{$project_name}}/v1 # used from `text/template` variables
  - internal/{{.vars.file_path}} # used from `vars` section
  - internal/{{.vars.file_path_2}} # used overridden `vars` which set through args (-tvar=.vars.file_path 2=override path)

% progen -v -dr -tvar=.vars.file_path_2=overrided_path
2023-02-05 14:51:38	INFO	application working directory: /Users/user_1/GoProjects/service

Skip `actions`

Set -skip flag to skip any action (only root actions: cmd, files, dirs). Value of the flag is a regular expression.

## progen.yml

  - api/v1
cmd:
  - chmod -R 777 api/v1

Lib

To use progen for building custom generator based on go language, imports pkg/core package and implements required algorithm:

package main

import (
	"log"
	"testing/fstest"

	"github.com/kozmod/progen/pkg/core"
)

var fs = fstest.MapFS{
	"1": {
		Data: []byte("aaaa"),
	},
}

func main() {
	// Parse default config base on flags
	c, err := core.ParseFlags()
	if err != nil {
		log.Fatal(err)
	}

	var e core.Engin

	// add actions
	e.AddActions(
		// create files actions
		core.FilesAction(
			"create_file",
			core.File{Path: "./xx/1", Data: []byte("file_1")},
			core.File{Path: "./xx/2", Data: []byte("file_2")},
			core.File{Path: "./xx/rm_1", Data: []byte("file_rm")},
		).WithPriority(1),
		// rm actions
		core.RmAction(
			"rm",
			"./xx/rm_1",
		).WithPriority(2),
	)
	e.AddActions(
		// create file system action
		core.FsSaveAction(
			"fs_1",
			core.TargetFs{
				TargetDir: "./xx/fs",
				Fs:        fs, // any [io/fs.FS] (from local system, embed, etc.)
			},
		).WithPriority(3),
		
		// cmd action
		core.CmdAction(
			"tree_1",
			core.Cmd{
				Cmd: "tree",
				Dir: "./xx",
			},
		).WithPriority(4),
	)

	err = e.Run(c)
	if err != nil {
		log.Fatal(err)
	}
}
