Buildsystem

This is a very simple build system written in python that is hackable and easy to extend. The problem I had so far with other build systems was the lack of scripting ability that I needed many times.

Installation

In order to install the latest release of buildsystem, run the following command:

pip install buildsystem

How to use

Here's an example on how to use the MsdevBuilder. The MsdevBuilder allows you to compile and clean your Msdev-Solution (.sln) and specify some options. Here's an example usage file build.py:

from buildsystem.msdev import MsdevBuilder

msdevbuilder = MsdevBuilder()
msdevbuilder.conf(product_title='SIMAVIS H',
             solution_file='src/simavis_h.sln',
             target='simavis_h',
             build_conf='Release',
             log_enabled=True)
msdevbuilder.log_enabled = False
msdevbuilder.build()

As you can see there are some properties we could define. You have multiple options to set them, either by calling the conf method, or by setting them via direct call.

How to add your own builder

Adding your own builder is very easy. You just have to create a new class that inherits from Builder and add your tasks in that order to be executed and add to each of them the task decorator. Here is an example (reate a file called simple.py):

from buildsystem.builder import Builder, task

class MyBuilder(Builder):
    # here you could declare some configuration properties if you want to
    my_name = 'Nobody'
    
    @task('greet-me')
    def greet_me(self):
        # to output something with the right indentation, use self.output
        # You can define the color by specifying an ok=True, warn=True or error=True.
        self.output('Hello ' + self.my_name + '. ', ok=True)
    
    @task('greet-all')
    def greet_world(self):
        self.output('Hello to all others! ')

You can now use it by simple writing

from simple import MyBuilder

builder = MyBuilder()
builder.my_name = 'Conroe'
builder.build()

Commandline options

If you want to skip some tasks, you can do this by adding them to the skip list by just calling

builder.skip.append('greet-all')

If you want to only execute some tasks you can call your build script with the task-names of the arguments you want to run:

python build.py greet-me

This would only run the greet_me method and output the greet-all task as skipped.

Using the git version info in an Inno Script setup file

The setup.py build script first creates a git.txt file containing the version information read from the git tags. After compiling the setup this file will be deleted. If you want to add the version information in your Inno Script setup, you just need to read this file by adding the following code to your Setup.iss file:

#define FileHandle
#define FileLine
#sub ProcessFileLine
  #pragma message FileLine
#endsub
#for {FileHandle = FileOpen("git.txt"); FileHandle && !FileEof(FileHandle); FileLine = FileRead(FileHandle)} ProcessFileLine
#if FileHandle
  #expr FileClose(FileHandle)
#endif
#define VERSION Copy(FileLine, Pos("/", FileLine) + 1)

After this you can use the VERSION constant by inserting {#VERSION} into your script, for example in your [Setup] section:

AppVersion={#VERSION}
