Many standards. The **Macro Core** library exists to save time and development effort! Herein ye shall find a veritable host of MIT-licenced, production quality SAS macros. These are a mix of tools, utilities, functions and code generators that are useful in the context of [Application Development](https://sasapps.io) on the SAS platform (eg https://datacontroller.io). [Contributions](https://github.com/sasjs/core/blob/main/.github/CONTRIBUTING.md) are welcome. You can download and compile them all in just two lines of SAS code: ```sas filename mc url "https://raw.githubusercontent.com/sasjs/core/main/all.sas"; %inc mc; ``` Documentation: https://core.sasjs.io ## Components ### BASE folder (All Platforms) - OS independent - Works on all SAS Platforms - No X command - Prefixes: `mf_`, `mp_` ### DDL folder (All Platforms) - OS independent - Works on all SAS Platforms - No X command - Prefixes: `mddl_(lib)_` -> where lib can be "SAS" (in relation to a SAS component) or "DC" (in relation to a Data Controller component) This library will not be used for storing data entries (such as formats or datalines). Where this becomes necessary in the future, a new repo will be created, in order to keep the NPM bundle size down (for the benefit of those looking to embed purely macros in their applications). ### FCMP folder (All Platforms) - Function and macro names are identical, except for special cases - Prefixes: `mcf_` The fcmp macros are used to generate fcmp functions, and can be used with or without the `proc fcmp` wrapper. ### LUA folder Wait - this is a macro library - what is LUA doing here? Well, it is a little known fact that you CAN run LUA within a SAS Macro. It has to be written to a text file with a `.lua` extension, from where you can `%include` it. So, without using the `proc lua` wrapper. To contribute, simply write your freeform LUA in the LUA folder. Then run the `build.py`, which will convert all files with a ".lua" extension into a macro wrapper with an `ml_` prefix (embedding the necessary data step put statements). You can then use your module in any program by running: ```sas /* compile the lua module */ %ml_yourmodule() /* Execute. Do not use the restart keyword! */ proc lua; submit; print(yourStuff); endsubmit; run; ``` - Prefixes: `ml_` ### META folder (SAS9 only) Macros used in SAS EBI, which connect to the metadata server. - OS independent - Metadata aware - No X command - Prefixes: `mm_` ### METAX folder (SAS9 only) - OS specific - Metadata aware - X command enabled - Prefixes: `mmx_` ### SERVER folder (@sasjs/server only) These macros are used for building applications using [@sasjs/server](https://server.sasjs.io) - an open source REST API for Desktop SAS. - OS independent - @sasjs/server aware - No X command - Prefixes: `ms_` ### VIYA folder (Viya only) Macros used for interfacing with SAS Viya. - OS independent - No X command - Prefixes: `mv_`, `mvf_` ### XPLATFORM folder (Viya, Meta, and Server) Sometimes it is helpful to use a macro that can be used interchangeably regardless of the server type on which is is running (SASVIYA, SAS9, SASJS). - OS independent - No X command - Prefixes: `mx_` ## Installation First, download the repo to a location your SAS system can access. Then update your sasautos path to include the components you wish to have available, eg: ```sas %let repoloc=/your/path/core; options insert=(sasautos="&repoloc/base"); options insert=(sasautos="&repoloc/ddl"); options insert=(sasautos="&repoloc/fcmp"); options insert=(sasautos="&repoloc/lua"); options insert=(sasautos="&repoloc/meta"); options insert=(sasautos="&repoloc/metax"); options insert=(sasautos="&repoloc/server"); options insert=(sasautos="&repoloc/viya"); options insert=(sasautos="&repoloc/xplatform"); ``` The above can be done directly in your sas program, via an autoexec, or an initialisation program. Alternatively - for quick access - simply run the following! This file contains all the macros. ```sas filename mc url "https://raw.githubusercontent.com/sasjs/core/main/all.sas"; %inc mc; ``` ## Standards ### File Properties - filenames much match macro names - filenames must be lowercase, without spaces - macro names must be lowercase - one macro per file - prefixes: - _mcf__: macro compiled functions (proc fcmp) - _mddl__: macros containing DDL (Data Definition Language) - _mf__: macro functions (can be used in open code). - _mfv__: macro functions that work only in Viya - _ml__: macros that are used to compile LUA modules - _mm__: metadata macros (interface with the metadata server). - _mmx__: macros that use metadata and are XCMD enabled (working on both windows and unix) - _mp__: macro procedures (which generate sas code) - _ms__: macro procedures that will only work with [@sasjs/server](https://github.com/sasjs/server) - _mv__: macro procedures that will only work in Viya - _mx__: macros that work on Viya, SAS 9 EBI and SASjs Server - follow verb-noun convention - unix style line endings (lf) - individual lines should be no more than 80 characters long - UTF-8 ### Header Properties The **Macro Core** documentation is created using [doxygen](http://www.doxygen.nl). A full list of attributes can be found [here](http://www.doxygen.nl/manual/commands.html) but the following are most relevant: - file. This needs to be present in order to be recognised by doxygen. - brief. This is a short (one sentence) description of the macro. - details. A longer description, which can contain doxygen [markdown](http://www.stack.nl/~dimitri/doxygen/manual/markdown.html). - param. Name of each input param followed by a description. - return. Explanation of what is returned by the macro. - version. The EARLIEST SAS version in which this macro is known to work. - author. Author name, contact details optional All macros must be commented in the doxygen format, to enable the [online documentation](https://core.sasjs.io). #### Dependencies SAS code can contain one of two types of dependency - SAS Macros, and SAS Includes. When compiling projects using the [SASjs CLI](https://cli.sasjs.io) the doxygen header is scanned for ` @li` items under the following headers: ```sas

SAS Macros

@li mf_nobs.sas @li mm_assignlib.sas

SAS Includes

@li somefile.ddl SOMEFREF @li someprogram.sas FREFTWO ``` The CLI can then extract all the dependencies and insert as precode (SAS Macros) or in a temp engine fileref (SAS Includes) when creating SAS Jobs and Services (and Tests). When contributing to this library, it is therefore important to ensure that all dependencies are listed in the header in this format. ### Coding Standards - Indentation = 2 spaces. No tabs! - no trailing white space - no invisible characters, other than spaces. If invisibles are needed, use hex literals. - Macro variables should not have the trailing dot (`&var` not `&var.`) unless necessary to prevent incorrect resolution - The closing `%mend;` should **not** contain the macro name. - All macros should be defined with brackets, even if no variables are needed - ie `%macro x();` not `%macro x;` - Mandatory parameters should be positional, all optional parameters should be keyword (var=) style. - All dataset references must be 2 level (eg `work.blah`, not `blah`). This is to avoid contention when options [DATASTMTCHK](https://support.sas.com/documentation/cdl/en/lrdict/64316/HTML/default/viewer.htm#a000279064.htm)=ALLKEYWORDS is in effect, or the [USER](https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.5/lrcon/n18m1vkqmeo4esn1moikt23zhp8s.htm) library is active. - Avoid naming collisions! All macro variables should be local scope. Use system generated work tables where possible - eg `data ; set sashelp.class; run; data &output; set &syslast; run;` - Where global macro variables are absolutely necessary, they should make use of `&sasjs_prefix` - see mp_init.sas - The use of `quit;` for `proc sql` is optional unless you are looking to benefit from the timing statistics. - Use [sasjs lint](https://github.com/sasjs/lint)! ## General Notes - All macros should be compatible with SAS versions from support level B and above (so currently 9.3 and later). If an earlier version is not supported, then the macro should say as such in the header documentation, and exit gracefully. - It's [best to avoid](https://git.datacontroller.io/dc/dc/issues/50) special / non-ASCII characters for compatibility with the widest variety of SAS installations. ## Breaking Changes We are currently on major release v4. Breaking changes should be marked with the [deprecated](https://www.doxygen.nl/manual/commands.html#cmddeprecated) doxygen tag. The following changes are planned when the next major/breaking release (v5) becomes necessary: * mcf_xxx macros to have `insert_cmplib` option deprecated (the option is now checked automatically with value inserted only if needed) * mcf_xxx macros to have `wrap=` option defaulted to YES for convenience. Set this option explicitly to avoid issues. * mf_getuniquelibref.sas to have the deprecated maxtries parameter removed (no longer needed) * mp_abort.sas will have the redundant type= parameter removed. * mp_coretable.sas will be replaced by the standalone macros in the `ddl` folder (which are already available) * mp_getddl.sas to be renamed to mp_ds2ddl.sas (consistent with other ds2xxx macros). A wrapper macro is already in place, and you are able to use this immediately. The default for SHOWLOG will also be YES instead of NO. * mp_testservice.sas to be renamed as mp_execute.sas (as it doesn't actually test anything) ## Star Gazing If you find this library useful, please leave a [star](https://github.com/sasjs/core/stargazers) and help us grow our star graph! ![](https://starchart.cc/sasjs/core.svg) ## Other SAS Repositories The following repositories are also worth checking out: * [chris-swenson/sasmacros](https://github.com/chris-swenson/sasmacros) * [Criptic/sas_snippets](https://github.com/Criptic/sas_snippets) * [greg-wotton/sas-programs](https://github.com/greg-wootton/sas-programs) * [KatjaGlassConsulting/SMILE-SmartSASMacros](https://github.com/KatjaGlassConsulting/SMILE-SmartSASMacros) * [paul-canals/toolbox](https://github.com/paul-canals/toolbox) * [rogerjdeangelis](https://github.com/rogerjdeangelis) * [SASJedi/sas-macros](https://github.com/SASJedi/sas-macros) * [scottbass/sas](https://github.com/scottbass/SAS) * [xieliaing/SAS](https://github.com/xieliaing/SAS) * [yabwon/sas_packages](https://github.com/yabwon/SAS_PACKAGES) ## Contributors ✨ [![All Contributors](https://img.shields.io/badge/all_contributors-15-orange.svg?style=flat-square)](#contributors-) Thanks goes to these wonderful people ([emoji key](https://allcontributors.org/docs/en/emoji-key)):
