Hello everyone! A few fantastically productive days on the project later, I have a lot to show off! Check out these screenshots of the in-progress beats & measures ruler!

Accomplished this week:

• Added ability to switch between Beats & Measures and Minutes & Seconds rulers.
• Completely abstracted RulerFormat so custom data can be passed into it.
• Created BeatsFormat for the Beats & Measures ruler so a custom tempo and time signature can be passed in.
• Created algorithms to map the time ruler to beats given the tempo and time signature.

To accomplish this upcoming week:

• Add tempo and time signature selection to the bottom panel.
• Add beats display to the bottom panel.
• Add an option to default to the Beats & Measures ruler in the Preferences menu.
• Improve the look of the beats & measures ruler.

Hi everyone! Writing from Greece this week, doing a bit of travel for my last week of the summer! I’ve finished off the polymorphic ruler changes for a bit to do the beats-and-measures ruler. You can see the current final state of the polymorphic ruler here!

Accomplished this week:

• Made final changes towards polymorphic ruler; evaluated future changes, went back through commit history to fix issues, etc.
• Created equivalency function for updaters and implemented invalidation.

To accomplish this upcoming week:

• Create beats and measures ruler (follow the progress on this branch!)

Hi everyone! Not too much to update on. Current goal is to wrap up the last few changes necessary to call the updater changes done, then move on to the new time ruler.

Accomplished this week:

• Created SetUpdaterData function which fixed many bugs as well.
• Planned out tasks and worked through backlog.
• Improved structure and definition of Updaters through GeneratedUpdater class

To accomplish this upcoming week:

• Evaluate structure / privacy of defined data structures.
• Create equivalency function for updaters so they can be compared (necessary for efficient ruler invalidation)
• Clean up, simplify, and comment existing code and commit history.

Hi everyone, small update this week. I know that I’m a bit off-schedule from making the update every Monday, so the next update will come Tuesday-Wednesday and I will be on-track for the rest of the coding period from there.

Accomplished this week:

• Fixed issues with Linear Decibel ruler, up to point where design team consultation is needed.
• Began work on SetUpdaterData and polymorphism.
• Cleaned up old commits and code.

To accomplish this upcoming week:

• Finish SetUpdaterData to create Updaters that are truly separate from Rulers using polymorphism.
• Fix known bugs.
• Work towards cleaning out the backlog of all changes to the ruler so the bars & meters time ruler can be pursued.

Hi everyone! I wanted to withhold this week’s post until the midterm evaluation for Google Summer of Code, which we passed! I’m very excited for the second half of the project 🙂

I want to post a few images to demonstrate how far the project has come!

Accomplished this week:

• Developed the Linear Decibel ruler for waveforms.
• Fleshed out Custom Ruler options.
• Merged changes from Week 1 that separated units from text on labels into current code.

To accomplish this upcoming week:

• Fix known issues with Linear Decibel ruler (doesn’t work at non-default decibel ranges)
• Increase polymorphism of rulers through the create of a SetUpdaterData function that will pass whatever kind of context an updater needs to perform its function. This will reduce the dependence of Updater on Ruler even further.
• Clean up comments and past Git history, and improve code quality through name-changes and usage of constants.

Hello everyone! Sorry for the late post; this week is the biggest yet for the project! Check out the current working branch here!

Accomplished this week:

• Completely reworked Updater class to be simpler and easier to utilize.
• Separated Ruler information that is needed by the Updater from that which isn’t.
• Moved and refined a variety of functions.

To accomplish this upcoming week:

• Custom rulers will be available by Saturday.
• A vertical linear dB ruler will be available for testing by Monday!

Hi everyone! I’ve made lots of progress in developing infrastructure for both the nonlinear and custom rulers. I’m looking forward to begin testing and showing off the changes I make through these blog posts!

Accomplished this week:

• Broke the Ruler class into separate Updater files.
• Substantially rewrote existing ruler code to follow new polymorphic Updater standards.
• Cleaned up scoping inside Ruler and Updater to be more secure.

To accomplish this upcoming week:

• Implement invalidation for Updaters with runtime type identification.
• Debug and test polymorphism.
• Develop the nonlinear and custom options.

Happy 4th of July! Progress has gone smoothly this week. I’ve been making changes to the Ruler.cpp and Ruler.h files; you can follow along at my GitHub fork.

The timeline for the project has changed slightly; I am now targeting to finish the implementation of the nonlinear and custom rulers by the end of the 5th week, with the vertical linear dB waveform ruler taking only the 6th week.

Accomplished this week:

• Reworked Ruler class to be more easily expanded upon with polymorphism.
• Fixed various minor issues in code to improve clarity.

To accomplish this upcoming week:

• Finish implementation of the nonlinear options.

Hello again! This week has been a little slower than the last due to personal reasons. Still, progress continues; I’ve began implementing the nonlinear ruler options.

Accomplished this week:

• Identified issues that could motivate later parts of the project. (Advanced two-tone labelling on rulers. refactoring existing data structures, etc.)
• Began expansion of nonlinear ruler code. Designing code that will allow any function to be passed by the instance of the ruler, so that tick marks can be placed according to that function.
• Test options by editing existing ruler instances.

To accomplish this upcoming week:

• Finish implementation of the nonlinear options.
• If possible, begin work on custom options.

Hello everyone! Here are some updates on the current status of my GSoC Project. I have mainly taken this week to gain a better understanding of the Ruler code.

Accomplished this week:

• Investigated the source code for the Ruler. Created a map of the functions and how they relate to each other.
• Created a small project to better understand labelling. Separated the font of the label’s value from the units, allowing for more dynamic labelling.
• Discussed the project with mentors and communicated goals and expectations.

To accomplish this upcoming week:

• Implement a complete suite of options for a nonlinear ruler.
• Continue talking to mentors and better understanding the code.
