themify's Introduction

Fast Bio

I'm a professional program writer. Since I was a kid I wanted to deal with computers. My first contact with computers date back to 1982, when I met an Apple II machine. At that time, I was only 11. But only in 1986 I could get really interested in computers. My mother registered me on a BASIC course. So, I learned BASIC on TRS-80 based machines: Prologica CP-200 and Microdigital TK-85 and TK-90X.

But, in 1991, after six months of electrical engineering course, I learned Pascal. At that time, electrical engineering died for me, but computing was born. In 1994 I got my first job as a programmer: C programmer. I wrote lots of C code, using Sybase embedded SQL. And from there, I did not stop.

I learned several programming languages: BASIC, Pascal, C, C++, Visual Basic, Transact SQL, PL/SQL, TCL, TK, Python, Java, Javascript, Ruby, Python, Objective C, Swift, Objective C++, Smalltalk, LISP, Bourne and C shell scripting, Applescript, Lua, and the list keeps growing.

Along with the non-stoping list of programming languages, also comes a list of frameworks like Flask, Django, Django Rest Framework, Rails, Apple's Cocoa and so forth.

themify's Issues

Colors with alpha component

Possibility to theme colors with an alpha component.

Add a level for attributes

Today's theme structure have attributes mixed with element identification. It is a better idea do have a new level on element definition dictionary in order to hold attributes. This will simplify the parser a little and open a room for context-dependent elements.

loadThemes using a flat string

Create a loadThemes method capable to load themes based on a POSIX-like path stored in a string provided as parameter.

Support font adjustments

Add support for font customization

Better documentation

Library documentation is pretty poor. A better documentation is needed.

Add support to carthage

Add support to carthage dependency manager.

Use document bundle for themes

Instead of using plist files, it is interesting to have a document bundle to encapsulate a whole theme and its resources. Currently, themes are based only in colors. But, in the near future, it may be necessary to use background images for a better theme design.

Give ability to theme custom classes

Current implementation apply a color theme only to default classes. In order to extend this library flexibility, it should be interesting to consider custom classes as well.

Add support to code-driven themes

Currently themify operates on the appearance proxy level, giving the ability to change static elements on an application. However, there are scenarios where colors are decided based on well-defined states. But those states are not static, by dynamic.

So, there is no way to cover this scenario currently.

Not all text attributes are considered

Only text attributes that refer to colors and images are being considered. Some others, like strikeouts and specific formatting, are being ignored.

Make the manager a full singleton

There is no need to keep the manager as a normal class. Since it is a shared state of the app, makes no sense letting several instances of it available for development.

Add the real-time theme changing

Currently this library does not support exchanging themes in real time. If you apply a theme and try to apply other, the second may break.

For instance, let's say we have two themes A and B. Theme A changes both foreground and background colors of a UINavigationBar, However, B, changes only the foreground color, using whatever is Apple's default for the background color. If applied after theme A, theme B will still show the background color applied by A theme.

To fix it, it is necessary that the library saves the last applied theme and un-apply it when a new theme is applied. Also, some animation during theme transition is required.
