Replace

help:

• https://doc.wikimedia.org/pywikibot/master/_modules/scripts/replace.html
• https://www.mediawiki.org/wiki/Manual:Pywikibot/replace.py

The code for simple replacement of a letter or words in a specific phrase.

Replace phrase in all wiktionary

pwb.py replace -lang:el -family:wiktionary -xml:/public/dumps/public/elwiktionary/latest/elwiktionary-latest-pages-articles-multistream.xml.bz2 "κλίσ-'πρόβατο" "κλίση-'βούτυρο" -summary:"pwb.py replace κλίση πρόβατο = βούτυρο"

Add -ns:0 to search only in main namespace of wiktionary. Then, find all the other pages (Talks, etc with Search insource:xxxx)

Replace phrase in a category

pwb.py replace -lang:el -family:wiktionary -cat:"Ανδρικά ονόματα (αρχαία ελληνικά)" "{{λείπει η ετυμολογία|grc}}" "{{λείπει η ετυμολογία|τύπος=όνομα|grc}}" -summary:"pwb.py +τύπος=όνομα"

Replace in one category starting from character B

I need to start from specific letter, because the category is too big. e.g. for letter Γ γ (capital or lowercase) I add -titleregex:'^γ.'

pwb.py replace -lang:el -family:wiktionary -cat:"Κατηγορία:Λήμματα με προφορά (νέα ελληνικά)" "ɛ" "e" "ɔ" "o" ".ˈ" "ˈ" ".'" "ˈ" -titleregex:'^γ.'   -summary:"pwb.py ενημέρωση [[ΔΦΑ]]"

Replace 2 empty lines with 1 empty line + excepttext

Use -excepttext:"BLAHBLAH" Example: replace. except if the page has a specific expression. Use -excepttext:"BLAHBLAH"

pwb.py replace -regex -lang:el -family:wiktionary -ns:0 -xml:/public/dumps/public/elwiktionary/latest/elwiktionary-latest-pages-articles-multistream.xml.bz2 -excepttext:"{{clear}}\n===={{μεταφράσεις}}"  "{{clear}}\n\n===={{μεταφράσεις}}"  "{{clear}}\n===={{μεταφράσεις}}" '\s\n===={{μεταφράσεις}}====' '\n{{clear}}\n===={{μεταφράσεις}}===='  -summary:"{{clear}} πριν τις μεταφράσεις"

Replace empty line after Template + param

Example: at Translations section

Replace empty line

Template|param + empty line + asterisc which starts the next line as in

{{μτφ-αρχή|blahblah}}

* {{en}}: ...... etc

Use "({{μτφ-αρχή[^}]+}})\n\n(\*)" "\1\n\2"

[^}] means: any character which is NOT a curly bracket }

+ means: get a sequence with 1 character at least.

to make sure it works if a vertical pipe | does not exist, use an asterisc: [^}]*

Careful: asterisc has special meaning in regex. We need to put \ before it, if needed as simple text

This is the command: (repeat at dumps)

pwb.py replace -ns:0 -regex -lang:el -family:wiktionary -cat:"Νέα ελληνικά" "({{μτφ-αρχή[^}]+}})\n\n(\*)" "\1\n\2" -summary:"PAWS - συντήρηση: μείον κενές γραμμές στις Μεταφράσεις"

pwb.py replace -regex -lang:el -family:wiktionary -ns:0 -xml:/public/dumps/public/elwiktionary/latest/elwiktionary-latest-pages-articles-multistream.xml.bz2 "({{μτφ-αρχή[^}]+}})\n\n(\*)" "\1\n\2" -summary:"PAWS - συντήρηση: μείον κενές γραμμές στις Μεταφράσεις"

Template|param + empty line + < which starts the next line as in

{{μτφ-αρχή|blahblah}}

<!-- .....

as above.

ooops. problem

This is the command: (repeat at dumps)

pwb.py replace -regex -lang:el -family:wiktionary -ns:0 -cat:"Νέα ελληνικά" "({{μτφ-αρχή[^}]+}})\n\n(<)" "\1\n\2" -summary:"PAWS - συντήρηση: μείον κενές γραμμές στις Μεταφράσεις"

Template|param + empty line + Template:(( which starts the next line as in

{{μτφ-αρχή|blahblah}}

{{((}}

as above.

CAREFUL: symbol ( has special meaning in regex. We need to put \ before it, if needed as simple text

This is the command: (repeat at dumps)

pwb.py replace -ns:0 -regex -lang:el -family:wiktionary -cat:"Νέα ελληνικά" "({{μτφ-αρχή[^}]+}})\n({{\(\(}})" "\1\n" -summary:"PAWS - συντήρηση: μείον κενές γραμμές στις Μεταφράσεις"

Replace empty line after Template no param

Example: at Translations section

Replace empty lines at

===={{μεταφράσεις}}====
-- erase this line
{{μτφ-αρχή}}
-- erase this line
* {{en}}: ...... etc
-- erase this line
{{μτφ-μέση}}
-- erase this line
{{μτφ-τέλος}}

Command: do with -- > and without

1)
pwb.py replace -regex -lang:el -family:wiktionary -ns:0 -cat:"Νέα ελληνικά" "===={{μεταφράσεις}}====\n\n"   "===={{μεταφράσεις}}====\n" "{{μτφ-αρχή}}\n\n"   "{{μτφ-αρχή}}\n"  "\n\n{{μτφ-μέση}}" "\n{{μτφ-μέση}}" "\n\n{{μτφ-τέλος}}" "\n{{μτφ-τέλος}}"  -summary:"PAWS - συντήρηση: μείον κενές γραμμές στις Μεταφράσεις"

2)
pwb.py replace -regex -lang:el -family:wiktionary -ns:0 -cat:"Νέα ελληνικά" "{{μτφ-αρχή}}\n\n" "{{μτφ-αρχή}}\n"  "-->\n\n{{μτφ-μέση}}" "-->\n{{μτφ-μέση}}"  "-->\n\n{{μτφ-τέλος}}" "-->\n{{μτφ-τέλος}}"  -summary:"PAWS - συντήρηση: μείον κενές γραμμές στις Μεταφράσεις"

Replace phrase + any character

NOTE: -regex creates problems, skip it

replace phrase + any character + continue the phrase. e.g.

replace "{ grc-β-κλισ-σοφός|BLAHBLAHBLABLAH} " with "{ grc-κλίση-'καλός'} "

Our good friend Botaki writes:

pwb.py replace -regex -lang:el -family:wiktionary -cat:"Επίθετα (αρχαία ελληνικά)" "{{grc-β-κλισ-σοφός[^}]+}}" "{{grc-κλίση-'καλός'}}" -summary:"pwb.py {{grc-κλίση-'καλός'}}"

[^}]     means: any character which is NOT a curly bracket }

+     means: get a sequence with 1 character at least.

And to make sure it works if a vertical pipe | does not exist, use an asterisc:

pwb.py replace -lang:el -family:wiktionary -cat:"Επίθετα (αρχαία ελληνικά)" -regex "{{grc-β-κλισ-σοφός[^}]*}}" "{{grc-κλίση-'καλός'}}" -summary:"pwb.py {{grc-κλίση-'καλός'}}"

Replace within a template

1) σωστό σύμβολο τόνου   ˈ   και όχι απλή τυπογραφική απόστροφος   '

• !! Προσοχή να μην σβήνονται σύμβολα για πλάγια ή έντοντα γράμματα αν υπάρχουν ΜΕΣΑ στο {{ΔΦΑ}}

2) Αλλαγή του τελεία + τόνος. Μόνον ο τόνος είναι απαραίτητος (σημαίνει, αλλαγή συλλαβής). Δεν γράφουμε, και τελεία, και τόνο.

pwb.py replace -regex -lang:el -family:wiktionary -ns:0 -xml:/public/dumps/public/elwiktionary/latest/elwiktionary-latest-pages-articles-multistream.xml.bz2 "({{ΔΦΑ[^}]+)\.ˈ([^}]*}})" "\1ˈ\2"  -summary:"pwb.py ΔΦΑ (ipa) update, not dot+accent"

No brackets μέσα στο ΔΦΑ [] // Χρειάζεται escape me \[ \] \/ (δυο φορές η πλαγιοκάθετη: πιάνει και το πρώτο και το δεύητερο)

pwb.py replace -regex -lang:el -family:wiktionary -ns:0 -xml:/public/dumps/public/elwiktionary/latest/elwiktionary-latest-pages-articles-multistream.xml.bz2 "({{ΔΦΑ[^}]+)\/([^}]*}})" "\1\2" "({{ΔΦΑ[^}]+)\/([^}]*}})" "\1\2" "({{ΔΦΑ[^}]+)\[([^}]*}})" "\1\2" "({{ΔΦΑ[^}]+)\]([^}]*}})" "\1\2" -summary:"pwb.py ΔΦΑ (ipa) delete internal brackets"

Αλλαγές συμβόλων: Τα σωστά σύμβολα που ισχύουν για όλες τις γλώσσες

• t͡s παλιά ʦ ή ts
• d͡z παλιά ʣ ή dz
• t͡ʃ παλιά t͜ʃ ή tʃ
• d͡ʒ παλιά ʤ
• ɡ (σύμβολο ipa και όχι το λατινικό g)

New symbols /t͡s/ και /d͡z/ and /t͡ʃ/ και /d͡ʒ/: cf. new rules

• with ⟨t͡s⟩ or ⟨t͜s⟩ (formerly with ⟨ʦ⟩ or ⟨ƾ⟩)

το ειδικό ɡ όχι g

pwb.py replace -regex -lang:el -family:wiktionary -ns:0 -xml:/public/dumps/public/elwiktionary/latest/elwiktionary-latest-pages-articles-multistream.xml.bz2 "({{ΔΦΑ[^}]+)g([^}]*}})" "\1ɡ\2"  -summary:"pwb.py ΔΦΑ (ipa) update σύμβολο ɡ"

μαζί και τα δύο:

pwb.py replace -regex -lang:el -family:wiktionary -ns:0 -xml:/public/dumps/public/elwiktionary/latest/elwiktionary-latest-pages-articles-multistream.xml.bz2 "({{ΔΦΑ[^}]+)g([^}]*}})" "\1ɡ\2" "({{ΔΦΑ[^}]+)ʣ([^}]*}})" "\1d͡z\2" "({{ΔΦΑ[^}]+)ʤ([^}]*}})" "\1d͡ʒ\2" "({{ΔΦΑ[^}]+)ʦ([^}]*}})" "\1t͡s\2" "({{ΔΦΑ[^}]+)ʧ([^}]*}})" "\1t͡ʃ\2"  -summary:"pwb.py ΔΦΑ (ipa) replace depracated symbols, ligatures [[Βικιλεξικό:Οδηγός_προφοράς#Αναφορές|cf. new rules]] & replace the latin g - απαρχαιωμένα σύμβολα"

Swap position within a template

H παράμετρος |γλ=... πάντα στην πρώτη θέση (τεχνικοί λόγοι)

pwb.py replace -regex -lang:el -family:wiktionary -ns:0 -xml:/public/dumps/public/elwiktionary/latest/elwiktionary-latest-pages-articles-multistream.xml.bz2 "({{ΔΦΑ)\|([^}]+)\|(γλ=[^}]+)}}" "\1|\3|\2}}"  -summary:"pwb.py ΔΦΑ (ipa) update move γλ="

Replace and swap position

ρηματικός τύπος

Κατηγορία:Ρηματικοί τύποι (αγγλικά) όπως abandoned.
Change {{ρημ τύπος|αόριστος και παθητική μετοχή|abandon}}
to {{infl|en|abandon||en-ed}}

pwb.py replace -regex -lang:el -family:wiktionary -cat:"Ρηματικοί τύποι (αγγλικά)" "({{ρημ τύπος)\|(αόριστος και παθητική μετοχή)\|([^}]+)}}" "{{infl|en|\3||en-ed}}"  -summary:"pwb.py update English forms -ed"

ετυμ

Note, that regex, escape characters etc are used at the REPLACED.sequenct, NOT at the result.sequence

[^}] means: any character which is NOT a curly bracket }

[^}\]] means: any character which is NOT a curly bracket } and NOT a bracket ]

I cannot write }] because the ] is a special character: I must put \ in front of it (escape character)

+ means: get a sequence with 1 character at least.

pwb.py replace -regex -lang:el -family:wiktionary -ns:0 -xml:/public/dumps/public/elwiktionary/latest/elwiktionary-latest-pages-articles-multistream.xml.bz2 "({{μτφδ}}\s{{ετυμ fr}}\s\[\[)([^}\]]+)(\]\])" "{{μτφδ|fr|el|\2|text=1}}"  -summary:"pwb.py Συντήρηση - auto replace {ετυμ fr}"

My notebook

I am at https://paws.wmflabs.org/paws/user/Sarri.greek/tree

• 1) Choose 'New'. A list pops up. Choose 'Text file'
• 2) now, I am at https://paws.wmflabs.org/paws/user/Sarri.greek/edit/untitled.txt
• 3) I write codes here for specific tasks. For #Replaceing I do not need this.
• 4) click 'File' > choose 'Rename'

  e.g. test01.txt https://paws.wmflabs.org/paws/user/Sarri.greek/edit/test01.txt

• 5) click 'File' > choose 'Save'

  Now i can see it under 'Files' at my notebook

Explanations

Terminal

https://www.mediawiki.org/wiki/Talk:Phabricator/Help

Now, I am at https://paws.wmflabs.org/paws/user/Sarri.greek/tree

Since 2022 there is A NEW SCREEN. Go to HELP and click Launch Classic Notebook

Choose New > Terminal

• OLD screen was https://paws.wmflabs.org/paws/user/Sarri.greek/terminals/1
• 2022 !!! a white screen apperas at https://hub.paws.wmcloud.org/user/Sarri.greek/lab
  • oh!!!! NOT 'retro' to see my previous screen: https://hub.paws.wmcloud.org/user/Sarri.greek/retro/tree

It says

@PAWS:~$

• 3) copy my code, and
• 4) click Enter

IF i write nothing at the black screen, I just exit this window:

• From central page, go to 'Running'. I see all my unused 'Terminal1', 'Terminal2' etc. Click the button 'Shutdown' to get rid of them.

Click letters

After clicking Enter at a code, you get each occurunce, with choices: [y]es [q]uit, etc: press the key in the bracket (e.g. y) + Enter, the key q + Enter... etc.

• [q]uit, it quits (as though you have pressed CTRL+C, but in a more final way)
• [N]no, it skips this occurance, and procedes to the next one
• [e]dit, ...
• [y]es, yes, do the changes and procede to the next one

Careful:

• [a]ll, does them all! one after the other. We do not click it unless having tried yes, several times

Code commands

Start the code at the black screen after @PAWS:~$ There is a blinking little square

• pwb.py   = I start with this
• what to do

  replace   = (our command: replace the first of the pairts I'm going to write)

• -lang:el   = at the el(.wiktionary)
• -family:wiktionary   = or wikipedia or wiki...
• -ns:0 = only in namespace: main
• -cat:"Κατηγορία:xxxxx" = only in this Category
• -titleregex:'^γ.' = when the first letter (^) is γ, followed by any character (.)
• (optional) -search:"xxxx"   = search for this sequence of characters
• first pair, if I need to replace:

  "xxxx"   = the sequence to be replaced

  "zzzz"   = the sequence with which we want to replace it

• I may add more pairs
• -summary:"pwb.py ...."   = describe the task
• \n = a line break
• These characters have special meaning in regex: . + * ? ^ $ ( ) [ ] { } | \

  if command -regex is used, and we wish to write them as text, we need escape character \ before them

Note, that regex, escape characters etc are used at the REPLACED.sequenct, NOT at the result.sequence

[^}] means: any character which is NOT a curly bracket }

[^}\]] means: any character which is NOT a curly bracket } and NOT a bracket ]

I cannot write }] because the ] is a special character: I must put \ in front of it (escape character)

+ means: get a sequence with 1 character at least.

Careful

• Do not leave too many spaces between the commands
• -pt:1 does everything in ONE second -must make trials first, then use with caution-. If something goes wrong, press CTRL+C (says my teacher, FocalPoint)
• summary: If by accident "zzzz"-summary are joined together, you will get a note about your summary
• use english keyboard to click letters
• PROBLEM with search and replace: if weird little diacritics are in the replace, things go wrong

Good ideas:

• add -ns:0 (namespace: main) if you do not wish to interfere with other pages. May check them later, manually.
• only in a specific category: instead of -xml:/public/dumps/...xml.bz2 I write: -cat:"Category in greek ωωω"

Examples

See User:Sarri.greek/PAWS/done

• NOTE: the 'search' command MAY NOT WORK. Try (Thank you Botaki for help!)

pwb.py replace -lang:el -family:wiktionary -xml:/public/dumps/public/elwiktionary/latest/elwiktionary-latest-pages-articles-multistream.xml.bz2 "κλίσ-'πρόβατο" "κλίση-'βούτυρο" -summary:"pwb.py replace κλίση πρόβατο = βούτυρο"

• 3b) NOT BEST WAY Now, e.g. I write next to that @PAWS:~$
  @PAWS:~$ pwb.py replace -lang:el -family:wiktionary -search:"Β:Χρηστικό" "Β:Χρηστικό" "Π:Χρηστικό" -summary:"pwb.py replace αντικατάσταση"

  pwb.py   = ...

  replace   = (our command: replace the first of the pairts I'm going to write)

  -lang:el   = at the el(.wiktionary)

  -family:wiktionary   = or wikipedia or wiki...

  -search:"xxxx"   = search for this sequence of characters

  "xxxx"   = the sequence to be replaced

  "zzzz"   = the sequence with which we want to replace it

• I may add more pairs

• 4) Now, I click ↵ Enter and Here is what i get:
