Write a parser for basic SPECL (just setting variables till we decide on our final approach)

[rburghol]

RESPEC issue development here: respec#99

• use branch psa https://github.com/HARPgroup/HSPsquared/tree/psa
• just parse, don't do anything. Parse and print out debug info.
• later merge with specl
• psa branch now successfully parses the "classic" style of special action, which just sets a state variable value
  • in main.py the variable specactions is populated, and can be viewed as: print(specactions['ACTIONS']['VALUE'])

Testing dataset:

git fetch origin psa
git checkout psa
git pull origin psa
cd [some dir]
wget https://deq1.bse.vt.edu/hsp2/land_spec.tar.gz
tar -xvf land_spec.tar.gz
cd land_spec
hsp2 import_uci hwmA51800.uci hwmA51800.h5
hsp2 run hwmA51800.h5

How Parsing is Done in hsp2

• All parsing code is in
• File HSP2tools/data/ParseTable.csv has lines for each supported UCI block
  • Lines are in format `#,section,block,routine,type' and
  • then the next 5 CSV items are the actual column description:
    • name, type_, start, end, default
  • One line per column in the UCI block
  • Ex: 1479,RCHRES,HYDR-PARM1,HYDR,PARAMETERS,OPNID,C,0,11, 1480,RCHRES,HYDR-PARM1,HYDR,PARAMETERS,VCONFG,I,11,14,0
• Code parseD (and parseD2 and parseD3) support different parse styles (hsp2 is not always consistent maybe?)
  • But all parseX()rely onfield = line[start:end].strip(), where start:endare in standar python array notation where start is the 0-based index and the end is the next non-used number. Ex:"abcdefg"[0:3] = "abc", which is array entries 0, and 2 -- not including entry 3.

Hey @jdkleiner check this out when you get to a place where we want to start loading data.

Testing:

Find and load the h5 file

library("rhdf5")
dir()
[1] "hwmA51800.h5"          "hwmA51800.uci"         "hwmA51800.wdm"
[4] "met_A51800.wdm"        "prad_A51800.wdm"       "pytables-8ng29y_8.tmp"

h5_file_path = "hwmA51800.h5"
fid = H5Fopen(h5_file_path) # Opens the h5 file, fid is a h5 identifier

Look for the SPECL table

• this works, but shows that the data parsing is off since all are NaN

data_source_table = "/SPEC_ACTIONS/ACTIONS/table"
did = H5Dopen(fid, data_source_table)

# alternative when conversion errors occur data <- H5Dread(did, bit64conversion = "double")
h5read(fid, "/SPEC_ACTIONS/ACTIONS/table")[1:2,]
  index OPERATION RANGE1 RANGE2 DC DS   YR MO DA HR MN D T VARI S1 S2 AC
1     0       NaN      1        DY    1984  1  1 12    2 3 FNO3       +=
2     1       NaN      1        DY    1984  2  1 12    2 3 FNO3       +=
     VALUE TC TS NUM CURLVL
1 0.000000                1
2 0.090044                1

Test the EXT SOURCES table

• this works fine, indicating that its parsing is sound

> h5read(fid, "/CONTROL/EXT_SOURCES/table")[1:2,]
  index SVOL SVOLNO SMEMN SMEMSB SSYST SGAPST MFACTOR TRAN   TVOL TGRPN  TMEMN
