Here’s anĮxample of how to apply that to a real-world Lilypond project with the Luser droog’s answer gives a good overview of make itself. abc files in a single directory, the whole thing is handled by a single rule: all: You can use a makefile just to collect one or more shell scripts together, ignoring much of the complexity of rules and dependencies if your situation is very simple.įor one project where I made a bunch of. Again, each of these commands must be indented with a bona fide ASCII TAB character. This example from the LilyPond docs shows that you can put multiple targets to the left of the colon, so you can account for both types of files produced by LilyPond which my example here doesn't do. For the other task of generating a list of files, there are some special variables available in GNU make for this.Īfter these definitions, you can use $(outputs) as a dependency in a rule, like: This handles just part of your shell loop, defining the transformation from an input file to an output file. Other useful variables are for the target, and $< for the first input if there are more than one. The %^ variable refers to the input file mentioned above. Note that the command to execute must start with a literal TAB character. pdf file, run lilypond on the corresponding. To replace your shell loop, you can use a pattern rule. If there's a rule for creating output1 later in the makefile it will use that.įor your case, I suggest making a top level rule to create Score.ly and Book.ly Invoking make with this makefile will try to create output1 if it doesn't exist. So a common technique is to make the first rule a "dummy" rule which doesn't produce a file but simply collects all the steps or outputs together. If you don't specify a target on the command line, it will invoke the first rule it encounters. The target or dependencies can be filenames or symbols that correspond to other rules. The format for a rule is the target followed by a colon, then a space delimited list of dependencies, followed by commands indented with TAB. Make operates by using rules for how to create an output from an input. If you use the uppercase 'M' then the file will usually be listed at the top according to alphabetical or collation order. Make will search the current directory for a file named Makefile or makefile, so it's often simplest to name it one of these two choices and then invoke with the simple command: pdfĬopyright.ily -+-* | |įrontpage.ily -* | The input-files of both voices have a format like this: \relative c. The Project has a file-structure like this: ├── Book.ly The command then simply looks like make -f Makefile run in the root directory of the project.) ( Edit: referring to a make man page I got my understanding as far as being able to say that one uses make as interpreter like bash on a shell-script.sh. How I would build it step by step and how I actually run the Makefile. ![]() ![]() So I though to take the time to make up an example project to ask, how a Makefile in this scenario could look like. ![]() Recently I started a project a little bigger than only one or two pages and once again I came across the article about Makefiles in the LilyPond Documentary.Įven though reading this article it was kinda hard for me to grasp the actual technique behind the template Makefile also because the article does not supply the file repository it is working with. During the last years I tought myself to write scores using LilyPond and furthermore to make file handling easier by using Bash scripts.
