We are going to dynamically recompile it during boot,īut please clean the :mime dependency to make sure it is recompiled: The :mime library has been compiled with the following custom types:īut it is being started with the following types: fetch_env! ( :mime, :types ) if app != MIME. Application do use Application require Logger def start ( _, _ ) do app = Application. # file: lib/mime/application.ex defmodule MIME. Since version 1.3.0 of the MIME library, the recompilation process isĪutomatic if the compile-time database is out of date. In the case you forget about doing that? Well, your changes will not takeĮffect until the dependency is manually recompiled, and before the releaseġ.3.0 you didn’t see any warning about it. We also mentioned that we need to recompile the library. When we started talking about how to add custom MIME types via configuration, Module.create/3 allow you to control the environment variables used whenĭefining the module. Module body is a quoted expression and another advantage is that Module.create/3, compared with fmodule/2, is preferred when the Line will create a module with the given name of MIME and it will be definedīy the previous quoted expression, keep in mind that the function Result of that invocation is stored in the quoted binding. Line, you can see a call to /1 passing as argument theĬustom MIME types defined via configuration or an empty map as a fallback, the create ( MIME, quoted, _ENV_ )īelieve me, that’s all the content on lib/mime.ex at the moment. Optimization that reduces the compilation time. The list represents the extensions, that’s why at the end of the forĬomprehension you can see an extra filter to ignore mime types that does not Substrings, the head of this list represents the mime type and the tail of Trailing whitespace and then splits that line or string into a list of To do the transformation, the MIME library reads the file line by line (viaįile.stream!/3) at compile time, and ignores empty lines or lines Returns the extensions associated with the given MIME type.Īpplication/octet-stream bin lha lzh exe class so dll img iso Let’s review real quick the MIME library API, most of the examples were takenįrom the MIME’s documentation page. MIME offers a short set of functions, which cover the most relevant cases when Lookup of the MIME database at runtime, that’s why new MIME types can only beĪdded at compile-time via configuration, but we’ll talk about this option One of the goals, maybe the main one, of this library is to offer a performant Then, I’ll focus on MIME’s internals or how wasīuilt, and also how MIME illustrates in an elegant way so many features of It’s a really compact projectĪnd includes nice features, which I’ll try to explain in case you’re notįamiliar with the library. Type database, so, users can map MIME (Multipurpose Internet MailĮxtensions) types to extensions and vice-versa. Elixir’s MIME is a read-only and immutable library that embeds the MIME
