As Kragen has demonstrated, there are cases where regular expressions will match some piece of source code, but they will ignore the context in which that bit of source code appears. This can lead to errors. While it might be possible to write smarter regular expressions for such cases as Kragen showed, they will quickly become extremely complex and hard to read/maintain/understand, because they have to consider many different possible contexts.
If you have to parse all the code... Dou you know grammar analyzers? When I studied 'language theory' we used grammars for parsing code. You can define a basic analizer with regex for the tokens (constants, reserved words, symbols, etc) and use a grammar analyzer for all the structure.
Use the pre-existing C# CodeDOM provider to get a structured representation of your source code by using the Parse method, then traverse it. This allows you to make a solution that can work for pretty much ANY .NET language.
Many text editors have advanced find (and replace) features. When I'm programming, I like to use an editor with regular expression search and replace. This feature is allows one to find text based on complex patterns rather than based just on literals. Upon occasion I want to examine each of the comments in my source code and either edit them or remove them. I found that it was difficult to write a regular expression that would find C style comments (the comments that start with /* and end with */) because my text editor does not implement the "non-greedy matching" feature of regular expressions.
SADLY javascript source code can not be lexed by a lexer/tokenizer alone, it needs help from a parser (or be a hybrid of lexer-parser all-in-one) to know the lexical context in the source! Without it, one can not know if slash (/) means division or regular expression literal.
PS: Extra note, lexer generators commonly accept their token-definitions as regular expressions (explained above), that however does not necessarily mean they actually use regular expressions (at least not all) in the resulting lexer code they generate.
I've been trying to get URxvt to work properly with Unicode characters but no matter what I do it always displays every Unicode character as a rectangle. I've attempted to use Font Awesome, Wuncon Siji, DejaVu, Source Code Pro, Terminus, and none of them are displaying these characters properly, or at least URxvt isn't loading those fonts properly. Honestly I'm not sure exactly what is going on.
I didn't have anything set for LC_CTYPE initially but now that I do it hasn't solved my problem. I suppose I should clarify that common Unicode symbols are showing up just fine. Such as the degree symbol that shows up when I run screenfetch. The problem is in files like my polybar config file, where there are slightly fancier symbols that are nearly impossible to edit if I wanted to because they just show up as rectangles. I've tried adding in all the fonts that my polybar config file is using and while that has worked for polybar, it does not appear to have worked for URxvt.
I think I'm starting to see the problem here and I'm not sure if it's something I can fix. What I'm gathering from some other experimenting I've been doing is that Wuncon Siji, the font that polybar is using to display symbols, uses different symbols for the same codepoints as other fonts. If I use the command in the comment above, but substitute Wuncon Siji, it shows me a different character than with any other fonts. So basically, even if I can get it to display the right characters for this situation, it may be the wrong characters for others. For example, the "play button" that polybar uses via Wuncon Siji font shows up as a different symbol in other fonts. I'm having trouble finding the codepoint, but it looks kinda like a T, except the bar on top is curved.
EDIT: It might be u+1E60
I managed to get it displaying the characters correctly by reinstalling the Siji font directly from github and then specifying it in my Xresources the "old-fashioned way" instead of the xft way. I do not know why I couldn't get it to work correctly when installing it via the package manager, but for now I am considering this fixed. Thank you all for your help.
The reason I wrote the findfont function how it currently is, was that I found it very difficult to choose the fonts I wanted in matplotlib, which also uses fontconfig I believe. It was difficult to select the font with the exact weight I wanted whenever it was more complicated than bold/italic. Many fonts have multiple weights such as semibold, roman, thin, light, etc. So I chose to use a function that goes just by the name (almost no user knows what weight 500 means for a font), but is a bit relaxed in what it matches, so that fonts with complicated names can be specified partially.
DEFINITIONS"Font Software" refers to the set of files released by the Copyright Holder(s) under this license and clearly marked as such. This may include source files, build scripts and documentation.
When writing code, however, your font requirements are typically more functional in nature. This is why most programmers prefer to use monospaced fonts with fixed-width letters, when given the option. Selecting a font that has distinguishable numbers and punctuation, is aesthetically pleasing, and has a copyright license that meets your needs is also important.
The first font on our list is FiraCode, a programming font that truly goes above and beyond the call of duty. FiraCode is an extension of Fira, the open source font family commissioned by Mozilla. What makes FiraCode different is that it modifies the common symbol combinations or ligatures used in code to be extraordinarily readable. This font family comes in several styles, notably including a Retina option. You can find examples for how it applies to many programming languages on its GitHub page.
Inconsolata is one of the most beautiful monospaced fonts. It has been around since 2006 as an open source and freely available option. The creator, Raph Levien designed Inconsolata with one basic statement in mind: "monospaced fonts do not have to suck." Two things that stand out about Inconsolata are its extremely clear differences between 0 and O and its well-defined punctuation.
Inspired by the copyrighted and closed Vera font family used in GNOME, DejaVu Sans Mono is an extremely popular programming font that comes bundled with nearly every modern Linux distribution. DejaVu comes packed with a whopping 3,310 glyphs under the Book Variant, compared to a standard font, which normally rests easy at around 100 glyphs. You'll have no shortage of characters to work with, it has enormous coverage over Unicode, and it is actively growing all of the time.
Designed by Paul Hunt and Teo Tuominen, Source Code Pro was produced by Adobe to be one of its first open source fonts. Source Code Pro is notable in that it is extremely readable and has excellent differentiation between potentially confusing characters and punctuation. Source Code Pro is also a font family and comes in seven different styles: Extralight, Light, Regular, Medium, Semibold, Bold, and Black, with italic variants of each.
Whichever typeface you select, you will most likely spend hours each day immersed within it, so make sure it resonates with you on an aesthetic and philosophical level. Choosing the right open source font is an important part of making sure that you have the best possible environment for productivity. Any of these fonts is a fantastic choice, and each option has a powerful feature set that lets it stand out from the rest.
Just from your examples, I would say that either DejaVu Sans and Source Code Pro are about equally readable. Firacode has funky-looking ampersand and @. Inconsolata shows the problem of differentiating a lower case L from a number one. Noto Mono shows the lower case L problem and also trouble between letter O and number zero. These are big problems with fonts because you often don't have the usual language context to help decide this characters.

The font is an open-source Monospaced development from Adobe. The package provides fonts (in both Adobe Type 1 and OpenType formats) and macros supporting their use in LaTeX (Type 1) and XeLaTeX/LuaLaTeX (OTF).
Since Source Code Pro does not have coding ligatures (connecting characters for symbols like arrow), and is open-sourced so others could modify the font, Hasklig was created to fulfill the need for coding ligatures. So if you want Source Code Pro but with coding ligatures, give Hasklig a try.

600+ lines of code (and counting) to replicate what SwiftUI is doing to have the equivalent of its getters... I will not show the other version (much shorter but obviously much more dangerous) that reverse engineers SwiftUI internals to to Font internals.
