Use JamBase to Build a Custom Application
JamBase is an online database and news portal focused on live music, particularly jam bands. Founded in 1998 by Andy Gadiel and Ted Kartzman, JamBase primarily functions as a service that makes live music information readily available to the public. Through an API, concert promoters can easily publish their data on JamBase. But what exactly does JamBase do? And how can you use it to build a custom application?
Variables
One way to write a Java program that uses Jambase is to define rules that use variables. This is often done with an environment variable. The environment variable can point to the root directory of the source tree, or to a specific target. For example, you might set a top-level environment variable to point to your top-level project, or just to the directory itself. Then, you can create the Jamfile in $(TOP)/src/util, and have it compile four Java files. The resulting program will archive two objects into libtree and link into myprog.
Jambase rules are read from the Jamfile. The Jamfile defines what to do with the source files. Depending on the environment, other directories can be read as well. Another option is a Jamrules file. It defines site-specific processing. If you use this file, then you can specify the target to build in a header file. You can also specify the path of the file that you want to search for.
When you use a command, you can specify a Jamfile name, such as -dax. The “-dax” flag allows you to run a shell command in the context of the Jambase. This flag is only supported on UNIX and NT. For Windows, “-dax” allows you to execute multiple shell commands at once. You can also modify the behavior of the Jamfile by using special built-in rules, such as ALWAYS, LEAVES, NOUPDATE, TEMPORARY, or PERMANENTLY.
You can also use variables inside your rule, such as case.8 and case.l for all cases. For example, if you want to test your application with case.l, the BeMain rule is the most important rule. The BeMain rule is a real workhorse for the Jamfile-engine. You can even use this rule in a custom application to store the result of a search.
Objects
The Object rule is responsible for building object files. It must have a LINKLIBS variable specified that specifies the libraries to use. Normally, the Main and Library rules set the LINKLIBS variable. However, the Objects rule has a dependency on obj. If this rule is not set, then the Java object will not be generated. Therefore, if you want to build object files using Java, you need to set LINKLIBS accordingly.
The main rule in a Jamfile describes how Jambase should treat the source files. It specifies what to do with a source file based on its content. Jamfiles may be stored in a different directory. A Jamrules file is also used to define site-specific processing. In this file, the target(s) to the left of the colon is what gets built. When the colon is not present, the target is not built.
During the “file binding” phase of Jam, the Object rule sets the dependencies between the included files and the source files. This rule uses HdrRule and passes the target-specific values to the included files. This rule can be used to set the output directory as well. The Object rule is a powerful tool for creating complex object-based applications. But, it is not the only tool available. Jam is an open source program and uses Java code to build it. Jam’s object-based programming language is free and has many applications and libraries.
The rules are also referred to as targets, file targets, and pseudotargets. A file target is an object in a file system, while a pseudotarget represents another target. The libtree library, for example, is a target of Jambase. And the “all” target is a dependency of almost all targets. Jam builds its targets in the order they need them. This rule allows Jam to use the libraries it needs in order to build the object.
Related rules
The Jambase file provides the list of the rules that you can use in a particular project. For example, when you create an application in Jambase, you can make the project depend on the lib rule. This is a good idea because this rule will prevent Jam from creating files that do not have a specific extension. Another rule that you can use is the Object rule. This rule is very similar to the Object rule, but it takes a different approach.
When you create a project with Jambase, you can specify the target files. Jam will automatically detect if the target file is outdated and mark it for the updating phase. If it does not, you can modify this behavior with the built-in rules. Jam has four phases of operation. Here’s a summary of some of the key rules:
The rule NOUPDATE ignores timestamps on targets, but it does not remove them. This rule has two effects: it allows you to manually update a target without updating the other targets. It also allows you to delete archived object files. Jambase uses this rule to mark objects in its library. However, it does not apply to files that are used for development. However, you can also create an archived object file in Jambase.
The Jamrules file contains user-provided rules and variable definitions shared across the source tree. It can be customized automatically using autoconf (GNU). If you have a Jamrules file, you can set an environment variable to point to it. The environment variable you set for Jamrules can be given any name you like. You can also customize it with autoconf, but it’s best to specify a name that will make it easy to recognize.
Cc rule
The Cc rule on Jambase sets the value of a target-specific variable called $(CCFLAGS) to current value. This can be useful for testing system features, such as enabling error handling. To avoid building a file with invalid dependencies, this rule should be placed in a Jamfile. The following examples demonstrate how to use a Cc rule on Jambase. Let’s take a closer look at each one.
A Cc rule on Jambase moves the output object file to a specified directory. The cc command has a broken option -o, so it should be used with caution. Another example of a Cc rule would be the GLOB rule, which returns files matching the criteria given in a directory. This is very useful when a file has multiple locations, such as a database or directory. It also allows Jam to run on other computers, including Linux.
A Cc rule on Jambase is a code-based feature of the compiler. It enables Jambase users to compile and link their programs. They can add a switch to the Object rule to define a Cc rule for a file and apply it on the entire database. This is especially useful when the Jamfile contains multiple source files. The Cc file can be defined by Jamrules. Jambase also supports yyacc, which is a popular programming language.
A Cc rule on Jambase is useful when working with a project on another machine. The same applies to Jambase’s internal environment. If the file isn’t available, Jambase will default to the classical behaviour. The corresponding environment variables are BCCROOT, MSVC, and MSVCNT. If none of these variables is defined, Jambase will print a message. If you need to change the Cc rule on Jambase, it will be automagically updated by the system.
