Detailed Description

Insert config file data into a Fortran namelist file.

This class parses an input file that contains a partial namelist, inserting missing values of the format <s:cycle> with values from a ConfigParser-like object. The <s:cycle> sorts of text follow a specific format:

• <s:varname> – insert a string surrounded by double quotes taken from the specified conf variable
• <f:varname> – insert a float, taken from conf variable varname
• <r:varname> – same as <f:varname>
• <i:varname> – insert an integer, taken from conf variable varname
• <l:varname> – insert a logical, taken from conf variable varname
• <b:varname> – same as <l:varname>

<d:varname> – the conf variable is converted to a datetime.datetime using hwrf.numerics.to_datetime, and then to a string of the format "YYYY-MM-DD_HH:MM:SS". If atime is specified to the parse subroutine, then the value is allowed to be a difference relative to the atime (as accepted by hwrf.numerics.to_datetime_rel).

<u:varname> – convert the conf variable to a string, and dump its value unquoted. This is used, for example, to have the name of a namelist variable be generated from a conf file.

You can also specify angle braces without a type:

<varname>

to ask for the variable to be converted by guessing the type that was intended in the conf file. For example:

This conf file:

[conf]
var=T,F,T

With this namelist:

&nl
  myvar=@<var@> / 

will produce:

&nl
  myvar=.true., .false., .true. /

As for variables, one can request a subitem of a variable:

• varname – get variable varname
• vit[stormname] – get variable "vit" and then get vit.__getitem__["stormname"]

for subscriptable types. This is mainly intended for vitals.
