Python 3: RegEx Back References

Regual Expressions is one of those things that isn't completely regular when switching between languages. This is how you use a back reference in Python.

 
import re

print( re.sub(r'(foo)(bar)',r'\g<2>\g<1>','foobar'))

Python 3: solving 'utf-8' codec can't decode byte 0x92

In Python 3, UTF-8 is the default encoding. In windows you may run into issues where characters will not decode such as 'utf-8' codec can't decode byte 0x92. Use a header with either cp1252 or windows-1252

 

# coding=CP1252
import re

text = """
LADY CAPULET
    Alack the day. She’s dead, she’s dead, she’s dead!
CAPULET
    Ha! Let me see her. Out, alas! She’s cold.
    Her blood is settled, and her joints are stiff.
    Life and these lips have long been separated.
    Death lies on her like an untimely frost
    Upon the sweetest flower of all the field.
Nurse
    O lamentable day!

Autosys: Changing output of autosys -j JOB_NAME into Markdown

When generating output using autosys -j command line, it produces an output using space delimited typical console output.  The following command will output the result into a markdown table.


autorep -j YOUR_JOB_OR_BOX_NAME | sed -e 's/ \{2,\}/|/g'| sed -e 's/_\{2,\}/ /g' | sed 's/\(.*\)/|\1/g' | sed -e 's/\(Job Name\)/|\1/g' | sed -e 's/\(Last Start\)/|\1/g' | sed -e 's/\(Last End\)/|\1|/g'| sed -e 's/ST Run/ST||Run/g' | sed -e 's/Ntry Pri\/Xit/Ntry||Pri\/Xit||/g'| sed -e 's/\(.*\)\([0-9]\{8\}\/[0-9]*\)/\1|\2|/g'

Python: Performing XSLT recursively on a directory of XML files

I've been using https://github.com/ajryan/RptToXml to extract out xml information from Crystal Reports. I then rip through the created xml files with xlst to provide detail information on how the reports are created.  This little python 3.5+ script uses https://www.saxonica.com/download/download_page.xml and will create html files from a directory tree containing xml files.  

TODO: Write an xxl file to convert Crystal Reports to Jasper Reports.


import os
import subprocess
import glob
from pathlib import Path
root_dir = r"C:\crystalxml"
xslFile = r"C:\Saxon\pretty.xsl"

for filename in glob.iglob(root_dir + '/**/*.xml', recursive=True):

 my_parts = filename.split("\\")
 justname = my_parts[-1].split('.')[0]
 my_dir = os.path.dirname(filename)
 newname = fr'{my_dir}\{justname}.html'
 cmd = fr'java -cp C:\Saxon\saxon-he-10.1.jar net.sf.saxon.Transform -t -s:"{filename}" -xsl:{xslFile} -o:"{newname}"'
 subprocess.call(cmd)

Python: Learning by starting with the basics.

Just a simple mind exercise in learning a language.  Created a console Hangman game that uses a word api with a hint command that fills in the first available blank.

Oracle: Capitalizing and removing underscores from a column name

Oracle table names are all caps with underscores.  So if you're consuming them from something like all_tab_columns, this quick little function makes them a little prettier. 

select initcap(replace(lower('SOME_COLUMN_NAME'),'_',' ')) from dual;

VBA: A little function to Capitalize and Split a String

Here's a subroutine for converting a range of strings into a space separated Capitalization (i.e.) "FOO_BAR" becomes "Foo Bar"


Sub Capitalization_Split()
'Declaring variables
Dim Cell As Range
Dim Source As Range
Dim Capitalized As String
Dim Humps As Variant
Dim Hump As String
Dim i As Long
'Initializing source range
Set Source = Application.Selection
'Looping through each cell in the source range
For Each Cell In Source
    Capitalized = ""
    Hump = Cell.Value
    Humps = Split(Hump, "_")
    For i = LBound(Humps, 1) To UBound(Humps, 1)
        Hump = UCase(Left(Humps(i), 1)) & LCase(Right(Humps(i), Len(Humps(i)) - 1))
        Capitalized = Capitalized & Hump & " "
    Next
    Cell.Value = Capitalized 

Next
End Sub
