In TextMate 2, the standard themes are all in the Themes bundle. The rules for how a scope should be colored and styled, however, are to be found, not in the grammar itself, but in themes and also in settings. One of the chief reasons for writing a grammar is syntax coloring - which, like so much else about a grammar, depends on scopes. ![]() Here are some git log excerpts: Date: Wed Jan 15 13:59:57 2014 -0800įinally got recursively related match patterns working! (This was mostly because of undocumented things you mustn’t do and things that TextMate can’t do, both of which I tell you about later on this page.) After that, though, it was remarkably smooth sailing, and I was able to finish the entire grammar in a week. It then took me about three weeks of extremely frustrating, difficult work before I got my first two scopes working in the grammar. ![]() It took me some weeks just to prepare, collecting information and locating and studying the existing instructions and documentation. Writing a grammar can be a slow business. Having recently managed to write a grammar of my own for the first time, here are some things I learned along the way. The former is by far the simplest, the latter is a property list with environment variables read by Finder when you login, so values set here should affect all applications.Although TextMate has been around for a long time (in computer years) and many language bundles exist, it is startling to find that the process of writing a language grammar remains poorly documented. Either via Preferences → Advanced → Shell Variables or by editing ~/.MacOSX/ist. There are two ways to setup PATH for TextMate. TextMate inherits the value of PATH from Finder, which has only a few search locations specified, so for many users, it is necessary to augment this PATH if they need TextMate to find git, pdflatex, or similar commands not included with Mac OS X. For example ruby is located in /usr/bin/ruby and svn is (for me) located in /opt/local/bin/svn. When running a command from Terminal, the shell will use the value of the PATH variable to locate it (when it is specified without an absolute location). You can also set that documents should be saved before executing the command and give the command a key equivalent or tab trigger. for commands which build the project and show results, incrementally). ![]() for commands which lookup help for the current word) or HTML (e.g. you can set what to do with input/output, even have the output shown as a tool tip (e.g. The options here are the same as those of option 2, i.e. The first two options are mostly for one-shot commands, whereas commands created in the Bundle Editor are for stuff you want to run again later. In the current document, either press ⌃R with no selection to run the current line as a shell command, or select one or more lines and use ⌃R to run the selection as a shell script (it supports shebang as well).įrom the Text menu you can select Filter Through Command… (⌥⌘R) which opens a panel where you can enter a shell command to run and set what should be given as input (stdin) plus what to do with the output of the command (often you want to set input to the selected text and let the output replace the selection).Ĭommands via the Bundle Editor. TextMate allows shell commands to be executed in different contexts. as done when launching Terminal and entering commands to execute.įor a thorough introduction to the shell scripting language have a look at this shell tutorial provided by Apple. The shell is a scripting language used to piece together various programs (shell commands), and often in an interactive way, e.g.
