Pragmatism in the real world
As it becomes more painful to use a pointing device for long periods of time, I find myself using vim more and so I'm paying more attention to customisation so that the things I'm used to from Sublime Text are available to me. One thing I'm used to is that when I run the build command on a Markdown file, I expect Marked for Mac to open and render the file that I'm writing. Vim… continue reading.
Handling file uploads in Slim 3 is reasonably easy as it uses the PSR-7 Request object, so let's take a look. The easiest way to get a Slim framework project up and running is to use the Slim-Skeleton to create a project: composer create-project slim/slim-skeleton slim3-file-uploads and then you can cd into the directory and run the PHP built-in web server using: php -S 0.0.0.0:8888 -t public public/index.php Displaying the form We can now create… continue reading.
The Swift application that I'm currently developing gets data from Twitter and I was struggling to get a valid auth token. To solve this, I wanted to see exactly what I was sending to Twitter and so opened up Charles on my Mac to have a look. As my application is running within a Vagrant box running Ubuntu Linux, I needed to tell it to proxy all requests through Charles. To do this, you set… continue reading.
I discovered recently that if you walk through an array using array_walk or array_walk_recursive, then the array's internal pointer is left at the end of the array. Clearly this isn't something that I've needed to know before! This code example shows the fundamentals: $var = [ 'a' => 'a', 'b' => 'b', ]; array_walk($var, function ($value) { }); var_dump(key($var)); The output is NULL and you use reset() to put the internal pointed back to the… continue reading.
Zewo is a set of Swift packages that enable writing HTTP services. Most of the packages are focussed around this goal, but it also includes adapters for MySQL and PostgreSQL which is useful. The HTTP server is called Epoch and you can combine it with Router and Middleware to make a working API. To get going I wrote a simple /ping end point to see how it fits together. Epoch is built on libvenice (a… continue reading.
It's that time of year again where I look back at what happened over the past 12 months. Obviously this is mostly an excuse for me to look at the photos I've taken over the year and share some of them as I've done previously. I attended a lot of conferences this year, though one thing that was different this year was that I attended more than I spoke at. I also spoke at a… continue reading.
By default, libcurl writes the data it receives to stdout. This is less than useful when writing an application, as we want to store the received data internally and process it. This is done using the libcurl settings CURLOPT_WRITEFUNCTION which takes a function pointer where you can process the received data and CURLOPT_WRITEDATA which lets you set a pointer to something that can store the received data. You get access to this pointer within your… continue reading.
I can't use Composer because I'm using shared hosting and don't have SSH I've seen this sentiment a few times now, so this seems like a good time to point out that you do not need SSH access to your server in order to use Composer. In fact, I don't run Composer on a live server (regardless of whether it's using shared hosting) and it's not on my list of things to do in the… continue reading.
As I noted in my post about getting libcurl working with Swift, curl_easy_setopt() is a variadic function which means that Swift will not import it. If you try to use it you get this error: error: 'curl_easy_setopt' is unavailable: Variadic function is unavailable curl_easy_setopt(handle, CURLOPT_VERBOSE, true) ^~~~~~~~~~~~~~~~ CCurl.curl_easy_setopt:2:13: note: 'curl_easy_setopt' has been explicitly marked unavailable here public func curl_easy_setopt(curl: UnsafeMutablePointer, _ option: CURLoption, _ varargs: Any…) -> CURLcode ^ It's mildly annoying as curl_easy_setopt only… continue reading.
I'm still enjoying playing with Swift and am beginning to quite like the language. At the moment, I've only ever written with it on Linux, so I'm sure I'm making my life harder than if I was using OS X where it's more mature. On the flip side, if I ever use Swift professionally, it's most likely going to be on a Linux server as a microservice or a command line app at the other… continue reading.
