This is the basis for how TextMate uses HTML pages with errors to let you jump to a line number. This opens the textfile filename.txt at line number 14. the Safari Web browser or the Unix command open: $ open "txmt://open?line=14&url=file://filename.txt" Thus any program which handles URLs in OS X can potentially open a TextMate document. So any URL starting with txmt will cause a method in TextMate to be called which will be passed the URL. TextMate registers in its ist (contained in the Application bundle) the URL Scheme txmt. This is not limited to iOS, but also supported on Mac OS X. If you have done iOS development you would be familiar with the concept of URL Schemes. This script gets the result in CSV format and not JSON: output = `$TM_GOCODE -f=csv -in=# )'`)) Now we have enough information to execute the gocode command and get a list of completions. Since gocode can’t work with line and column number directly which is what TextMate sends our script through environment variables it has to calculate a byte offset like this: cursor = document.to_i - 1].join().length + ENV.to_i document = įile.open(ENV, "r+") do |file| This script does not pass the file in through STDIN. The TM_SUPPORT_PATH environment variable will always contain the path to scripts bundled with TextMate to help you make bundles. First the script load a whole bunch of ruby scripts which come bundled with TextMate: require ENV + '/lib/ui.rb' Our TextMate command consists of a Ruby script which invokes this command. This will look at at the 449th character in the source code file foobar.go and produce a list of possible completions formated in JSON. gocode can be invoked at the command line: gocode -f=json -in=foobar.go autocomplete 449 It is implemented as a ruby script which calls a unix command named gocode which you need to install like any other Go command. This bundle provides function and type completion through a command. This example is taken from the bundle which comes for the programming language Go. Example of a TextMate Command is Implemented you can configure your command to display output from STDOUT in a separate window, tooltip or just insert it right in your document at the caret. Anything you send to STDOUT can be shown by TextMate. Just as when debugging any other program without a dedicated debugger you can use printf style debugging. It configuration file might say to replace the current selection with the output from the script or insert the output at the caret. TextMate store a configuration file with your command which it reads to figure out how to pass data to it what to do with the data received back through STDOUT. Although it is for TextMate 1 it is very usefull for TextMate 2.Įnvironment variables are not suited for large amounts of data, so the bulk of data is sent in through STDIN.įor each command you can configure how information about current line, current selection etc is sent to your script. You can read about them in the Pragmatic Programmers TextMate book. There are a lot more environment variables. VariableĬontains text currently selected in document TextMate will setup its own environment variables before running your script. TextMate bundles’s on the otherhand are based on the unix philosophy of creating software by combining small programs which process text.Ī TextMate command is a script which receives its input from TextMate through regular environment variables and standard input. The downside of that is that you have to develop your plugin in a particular programming language. You don’t create a dynamically loaded library which adheres to some binary interface. TextMate is different from how you make plugins in a lot of IDEs. This allows you to do all kinds of cool stuff like creating command completion like you find in modern IDEs. However information about how you write these scripts seem to be scattered, so this is my attempt to help you get started writing scripts to extend TextMate 2. The cool thing about these scripts compared to vim and emacs is that you can write them in any language. Commands are external scripts you can invoke from TextMate. But what I want to talk about in this article is TextMate commands. You can create macros and snippets easily. One of the things I really like is the extension mechanisms. Like those editors it is very flexible when it comes to extending it while following modern GUI conventions. In many ways it is the modern decendant of vim and emacs. 1 note MaGet Started Writing TextMate 2 Bundles ![]()
