Andrew Johnson has proposed merging lp:~epics-core/epics-base/msi-join into lp:epics-base.
Requested reviews:
EPICS Core Developers (epics-core)
For more details, see:
https://code.launchpad.net/~epics-core/epics-base/msi-join/+merge/108420
This branch brings an updated version of the msi tool (and its HTML documentation) into Base. Additions to both msi and dbLoadRecords support defining global macros in substition files, and a flag for msi that changes substitution macros from local (the new default) to global scope (the original behavior).
Since msi only uses the macro substitution code from Base, this branch also builds a simple test program called dbltExpand which calls the dbLoadTemplate substitution file parser to help prove that the parser modifications made to both msi and dbLoadTemplate are compatible.
I also added a series of automated tests of msi into the build.

-<H2>NAME</H2><PRE>
- dbLoadRecords, dbLoadTemplate - load ascii database records
- into an IOC
-
-
-</PRE>
-<H2>SYNOPSIS</H2><PRE>
- dbLoadRecords(char* db_file, char* substitutions)
-
- dbLoadTemplate(char* template_file)
-
-
-</PRE>
-<H2>DESCRIPTION</H2><PRE>
- These routines are available from IOC core on the vxWorks
- command line. Both provide a way to load ascii ".db" files
- (usually created by <B>gdct(1)</B> ) into the IOC. The ".db" files
- contain ascii versions of record instances and are described
- in more detail in <B>dbfile(5)</B>. In addition to loading the
- ".db" ascii files into the IOC, both routines provide a
- method of performing variable substitution on record names
- and field values.
-
- dbLoadRecords() reads the ".db" file <I>db</I>_<I>file</I> performing sub-
- stitutions specified in string <I>substitutions</I>. The substitu-
- tion must be a string specified as follows:
-
- "var1=sub1,var2=sub3,..."
-
- Variables are specified in the ".db" file as
- $(variable_name). If the substitution string
- "a=1,b=2,c=\"this is a test\"" were used, any variables
- $(a), $(b), or $(c) would be substituted with the appropri-
- ate data. See the EXAMPLES section for more details.
-
- dbLoadTemplate() will read a <I>template</I>_<I>file</I>. The
- <I>template</I>_<I>file</I> resides in the your IOC boot directory and
- contains rules about loading ".db" files and performing sub-
- stitutions. The template_file must be in the form used by
- an IOC and is described in <B>templatefile(5)</B>. The EXAMPLES
- section descibes how it can be used.
-
-
-</PRE>
-<H2>EXAMPLES</H2><PRE>
- The next two examples of dbLoadRecords() and dbLoadTem-
- plate() will use the following ".db" file named <I>test</I>.<I>db</I> :
-
- database(test)
- {
- record(ai,"$(pre)testrec1")
- record(ai,"$(pre)testrec2")
- record(stringout,"$(pre)testrec3")
- {
- field(VAL,"$(STRING)")
- field(SCAN,"$(SCAN)")
- }
- }
- Running dbLoadRecords ("test.db","pre=TEST,STRING=\"this is
- a test\",SCAN=Passive") will produce the following records
- in the IOC's database:
-
- TESTtestrec1
- TESTtestrec2
- TESTtestrec3
-
- The third record will have VAL set to "this is a test" and
- SCAN set to "Passive".
-
- Running dbLoadTemplate ("test.template") with test.template
- containing:
- file test.db
- {
- {pre=TEST1, STRING = "this is a test two", SCAN="1 Second" }
- {pre=TEST2, STRING = "this is a test one", SCAN=Passive }
- {pre=TEST3, STRING = "this is a test three", SCAN=Passive }
- }
- will produce a total of nine records in the IOC's database:
- TEST1testrec1
- TEST1testrec2
- TEST1testrec3 - (VAL="this is a test two", SCAN="1 Second")
- TEST2testrec1
- TEST2testrec2
- TEST2testrec3 - (VAL="this is a test one", SCAN="Passive")
- TEST3testrec1
- TEST3testrec2
- TEST3testrec3 - (VAL="this is a test three", SCAN="Passive")
-
-
-</PRE>
-<H2>NOTES</H2><PRE>
- The binary file <I>default</I>.<I>dctsdr</I> must be loaded prior to run-
- ning either of these routines. This file contains the rules
- on how to construct records and change field values.
-
- After the default.dctsdr file is loaded, these routines can
- be run as many times as desired until iocInit is run.

+<h1>msi: Macro Substitution and Include Tool</h1>
+
+<h2>Introduction</h2>
+
+<p>msi is a general purpose macro substitution/include tool. It accepts as input
+an ascii template file. It looks for lines containing two reserved command
+names: <tt>include</tt> and <tt>substitute</tt>. It also looks for and performs
+substitutions on macros of the form $(var) and ${var}. It uses the macLib
+routines from EPICS Base to perform the substitutions, so it also accepts the
+default value and value definition syntax that macLib implements.</p>
+
+<p>msi also allows substitutions to be specified via a separate substitution
+file. This substitution file allows the same format as the substitution files
+accepted by the EPICS IOC's dbLoadTemplate command.</p>
+
+<h2>Command Syntax:</h2>
+
+<pre>msi -V -g -o<i>outfile</i> -I<i>dir</i> -M<i>subs</i> -S<i>subfile</i> <i>template</i></pre>
+
+<p>All parameters are optional. The -o, -I, -M, and -S switches may be
+separated from their associated value string by spaces if desired. Output will
+be written to stdout unless the -o option is given.</p>
+
+<p>Switches have the following meanings:</p>
+
+<dl>
+ <dt><tt>-V</tt></dt>
+ <dd>Verbose warnings; if this parameter is specified then any undefined
+ macro discovered in the template file which does not have an associated
+ default value is considered an error. An error message is generated, and
+ when msi terminates it will do so with an exit status of 2.</dd>
+
+ <dt><tt>-g</tt></dt>
+ <dd>When this flag is given all macros defined in a substitution file will
+ have global scope and thus their values will persist until a new value is
+ given for this macro. This flag is provided for backwards compatibility as
+ this was the behavior of previous versions of msi, but it does not follow
+ common scoping rules and is discouraged.</dd>
+
+ <dt><tt>-o</tt> <i>file</i></dt>
+ <dd>Output will be written to the specifed file rather than to the standard
+ output.</dd>
+
+ <dt><tt>-I</tt> <i>dir</i></dt>
+ <dd>This parameter, which may be repeated or contain a colon-separated (or
+ semi-colon separated on Windows) list of directory paths, specifies a search
+ path for include commands. For example:
+
+ <blockquote>
+ <pre>msi -I /home/mrk/examples:. -I.. template</pre>
+ </blockquote>
+
+ specifies that all named files should be searched for in the following
+ locations in the order given:
+
+ <ol>
+ <li><tt>/home/mrk/examples</tt></li>
+ <li><tt>.</tt> (the current directory)</li>
+ <li><tt>..</tt> (the parent of the current directory)</li>
+ </ol>
+ </dd>
+
+ <dt><tt>-M</tt> <i>substitutions</i></dt>
+ <dd>This parameter specifies macro values for the template instance.
+ Multiple macro values can be specified in one substitution parameter, or in
+ multiple <tt>-M</tt> parameters. For example:
+
+ <blockquote>
+ <pre>msi -M "a=aval,b=bval" -Mc=cval template</pre>
+ </blockquote>
+
+ specifies that in the template file each occurrence of:
+
+ <dl>
+ <dd><tt>$(a)</tt> or <tt>${a}</tt> is replaced by <tt>aval</tt></dd>
+ <dd><tt>$(b)</tt> or <tt>${b}</tt> is replaced by <tt>bval</tt></dd>
+ <dd><tt>$(c)</tt> or <tt>${c}</tt> is replaced by <tt>cval</tt></dd>
+ </dl>
+ </dd>
+
+ <dt><tt>-S</tt> <i>subfile</i></dt>
+ <dd>The substitution file. See below for format.</dd>
+
+ <dt><i>template</i></dt>
+ <dd> The input file. If no file is specified then input is taken from
+ stdin, i.e. msi can be used as a filter. See below for a description of
+ commands that can be embedded in the template file.</dd>
+</dl>
+
+<p>It is not possible to display usage by just typing <tt>msi</tt> since
+executing the command with no arguments is a valid command. To show usage
+specify an illegal switch, e.g.</p>
+
+<blockquote>
+<pre>msi -help</pre>
+</blockquote>
+
+<h2>Exit Status</h2>
+
+<dl>
+ <dt>0<dd>Success.
+ <dt>1<dd>Can't open/create file, or other I/O error.
+ <dt>2<dd>Undefined macros encountered with the <tt>-V</tt> option specified.
+</dl>
+
+<h2>Template File Format</h2>
+
+<p>This file contains the text to be read and written to the output after macro
+substitution is performed. If no file is given then input is read from stdin.
+Variable instances to be substituted by macro values are expressed in the
+template using the syntax <tt>$(</tt><i>name</i><tt>)</tt> or
+<tt>${</tt><i>name</i><tt>}</tt>. The template can also provide default values
+to be used when a macro has not been given a value, using the syntax
+<tt>$(</tt><i>name</i><tt>=</tt><i>default</i><tt>)</tt> or
+<tt>${</tt><i>name</i><tt>=</tt><i>default</i><tt>}</tt>.</p>
+
+<p>For example, using the command</p>
+
+<blockquote>
+<pre>msi -M name=Marty template</pre>
+</blockquote>
+
+<p>where the file template contains</p>
+
+<blockquote>
+<pre>My name is $(name)
+My age is $(age=none of your business)</pre>
+</blockquote>
+
+<p>results in this output:</p>
+
+<blockquote>
+<pre>My name is Marty
+My age is none of your business</pre>
+</blockquote>
+
+<p>Macro variables and their default values can be expressed in terms of other
+macros if necessary, to almost any level of complexity. Recursive definitions
+will generate warning messages on stderr and result in undefined output.</p>
+
+<p>The template file is read and processed one line at a time, where the
+maximum length of a line before and/or after macro expansion is 1023 characters
+— longer input or output lines will cause msi to fail. Within the context
+of a single line, macro expansion does not occur when the variable instance
+appears inside a single-quoted string, or where the dollar sign <tt>$</tt> is
+preceded by a back-slash character <tt>\</tt>, but as with the standard Unix
+shells, variables inside double quoted strings are expanded properly.</p>
+
+<p>However neither back-slash characters nor quotes of either variety are
+removed when generating the output file, so depending on what is being output
+the single quote behaviour may not be useful and may even be a hinderance. It
+cannot be disabled in the current version of msi.</p>
+
+<h3>Template file commands</h3>
+
+<p>In addition to the regular text and variable instances described above, the
+template file may also contain commands which allow the insertion of other
+template files and the ability to set macro values inside the template file
+itself. These commands are:</p>
+
+<blockquote>
+<pre>include "file"
+substitute "var=value,var=value,..."</pre>
+</blockquote>
+
+<p>Lines containing commands must be in one of these forms:</p>
+
+<ul>
+ <li><tt>include "</tt><i>filename</i><tt>"</tt></li>
+ <li><tt>substitute "</tt><i>name1=value1, name2=value2, ...</i><tt>"</tt></li>
+</ul>
+
+<p>White space is allowed before and after the command verb, and after the
+quoted string. If embedded quotes are needed, the backslash character
+<tt>\</tt> can be used as an escape character. For example</p>
+
+<blockquote>
+<pre>substitute "a=\"val\""</pre>
+</blockquote>
+
+<p>specifies that (unless <tt>a</tt> is subsequently redefined) wherever a
+<tt>$(a)</tt> macro appears in the template below this point, the text
+<tt>"val"</tt> (including the double quote characters) will appear in the
+output instead.</p>
+
+<p>If a line does match either syntax above it is just passed to macLib for
+processing without any notification. Thus the input line:</p>
+
+<blockquote>
+<pre>include "myfile" #include file</pre>
+</blockquote>
+
+<p>would just be passed to macLib, i.e. it would <em>not</em> be considered an
+include command.</p>
+
+<p>As an example of these commands, let the Unix command be:</p>
+
+<blockquote>
+<pre>msi template</pre>
+</blockquote>
+
+<p>and file includeFile contain:</p>
+
+<blockquote>
+<pre>first name is ${first}
+family name is ${family}</pre>
+</blockquote>
+
+<p>and template is</p>
+
+<blockquote>
+<pre>substitute "first=Marty,family=Kraimer"
+include "includeFile"
+substitute "first=Irma,family=Kraimer"
+include "includeFile"</pre>
+</blockquote>
+
+<p>then the following is written to the output.</p>
+
+<blockquote>
+<pre>first name is Marty
+family name is Kraimer
+first name is Irma
+family name is Kraimer</pre>
+</blockquote>
+
+<p>Note that the IOC's <tt>dbLoadTemplate</tt> command does not support the
+<tt>substitute</tt> syntax in template files, although the <tt>include</tt>
+syntax is supported.</p>
+
+<h2>Substitution File Format</h2>
+
+<p>The optional substitution file has three formats: regular, pattern, and
+dbTemplate format. We will discuss each separately.</p>
+
+<h3>Regular format</h3>
+
+<blockquote>
+<pre>global {gbl_var1=gbl_val1, gbl_var2=gbl_val2, ...}
+{var1=set1_val1, var2=set1_val2, ...}
+{var2=set2_val2, var1=set2_val1, ...}
+global {gbl_var1=gbl_val3, gbl_var2=gbl_val4, ...}
+{var1=set3_val1, var2=set3_val2, ...}
+{var2=set4_val2, var1=set4_val1, ...}</pre>
+</blockquote>
+
+<p>The template file is output with macro substitutions performed once for each
+set of braces containing macro replacement values.</p>
+
+<h3>Pattern format</h3>
+
+<blockquote>
+<pre>global {gbl_var1=gbl_val1, gbl_var2=gbl_val2, ...}
+pattern {var1, var2, ...}
+{set1_val1, set1_val2, ...}
+{set2_val1, set2_val2, ...}
+pattern {var2, var1, ...}
+global {gbl_var1=gbl_val3, gbl_var2=gbl_val4, ...}
+{set3_val2, set3_val1, ...}
+{set4_val2, set4_val2, ...}</pre>
+</blockquote>
+
+<p>This produces the same result as the regular format example above.</p>
+
+<h3>dbLoadTemplate Format</h3>
+
+<p>This format is an extension of the format accepted by the EPICS IOC command
+<tt>dbLoadTemplate</tt>, and allows templates to be expanded on the host rather
+by using dbLoadTemplate at IOC boot time.</p>
+
+<blockquote>
+<pre>global {gbl_var1=gbl_val1, gbl_var2=gbl_val2, ...}
+file templatefile {
+ <i>pattern format or regular format</i>
+}
+file "${WHERE}/template2" {
+ <i>pattern format or regular format</i>
+}</pre>
+</blockquote>
+
+<p>For the dbTemplate format, the template filename does not have to be given
+on the command line, and is usually specified in the substitutions file
+instead. If a template filename is given on the command line it will override
+the filenames listed in the substitutions files.</p>
+
+<h3>Syntax for all formats</h3>
+
+<p>A comment line may appear anywhere in a substitution file, and will be
+ignored. A comment line is any line beginning with the character <tt>#</tt>,
+which must be the very first character on the line.</p>
+
+<p>Global definitions may supplement or override the macro values supplied on
+the command-line using the <tt>-M</tt> switch, and set default values that will
+survive for the remainder of the file unless another global definition of the
+same macro changes it.</p>
+
+<p>For definitions within braces given in any of the file formats, a separator
+must be given between items. A separator is either a comma, or one or more of
+the standard white space characters (space, formfeed, newline, carriage return,
+tab or vertical tab).</p>
+
+<p>Each item within braces can be an alphanumeric token, or a double-quoted
+string. A back-slash character <tt>\</tt> can be used to escape a quote
+character needed inside a quoted string. These three sets of substitutions are
+all equivalent:</p>
+
+<blockquote>
+<pre>{a=aa b=bb c="\"cc\""}
+{b="bb",a=aa,c="\"cc\""}
+{
+ c="\"cc\""
+ b=bb
+ a="aa"
+}</pre>
+</blockquote>
+
+<p>Within a substitutions file, the file name may appear inside double quotation
+marks; these are required if the name contains certain characters or environment
+variable macros of the form ${ENV_VAR} or $(ENV_VAR), which will be expanded
+before the file is opened.</p>
+
+<h3>Regular substitution example</h3>
+
+<p>Let the command be:</p>
+
+<blockquote>
+<pre>msi -S substitute template</pre>
+</blockquote>
+
+<p>The file <tt>template</tt> contains</p>
+
+<blockquote>
+<pre>first name is ${first}
+family name is ${family}</pre>
+</blockquote>
+
+<p> and the file <tt>substitute</tt> is</p>
+
+<blockquote>
+<pre>global {family=Kraimer}
+{first=Marty}
+{first=Irma}</pre>
+</blockquote>
+
+<p>The following is the output produced:</p>
+
+<blockquote>
+<pre>first name is Marty
+family name is Kraimer
+first name is Irma
+family name is Kraimer</pre>
+</blockquote>
+
+<h3>Pattern substitution example</h3>
+
+<p>Let the command be:</p>
+
+<blockquote>
+<pre>msi -S pattern template</pre>
+</blockquote>
+
+<p>The file <tt>pattern</tt> contains</p>
+
+<blockquote>
+<pre>pattern {first,last}
+{Marty,Kraimer}
+{Irma,Kraimer}</pre>
+</blockquote>
+
+<p>and <tt>template</tt> is the same as the previous example:</p>
+
+<blockquote>
+<pre>first name is ${first}
+family name is ${family}</pre>
+</blockquote>
+
+<p>This is the output:</p>
+
+<blockquote>
+<pre>first name is Marty
+family name is Kraimer
+first name is Irma
+family name is Kraimer</pre>
+</blockquote>
+
+<h3>dbTemplate example</h3>
+Let the command be
+
+<blockquote>
+<pre>msi -S xxx.substitutions</pre>
+</blockquote>
+
+<tt>xxx.substitutions</tt> is
+
+<blockquote>
+<pre>file template {
+pattern {first,last}
+{Marty,Kraimer}
+{Irma,Kraimer}
+pattern {last,first}
+{Smith,Bill}
+{Smith,Mary}
+}
+file template {
+{first=Marty,last=Kraimer}
+{first=Irma,last=Kraimer}
+}</pre>
+</blockquote>
+<tt>template</tt> is the same as in the previous example..
+
+<p>The following is written to the output</p>
+
+<blockquote>
+<pre>first name is Marty
+family name is Kraimer
+first name is Irma
+family name is Kraimer
+first name is Bill
+last name is Smith
+first name is Mary
+last name is Smith
+first name is Marty
+family name is Kraimer
+first name is Irma
+family name is Kraimer</pre>
+</blockquote>
