FLExProject class

class flexlibs.FLExProject

This class provides convenience methods for accessing a FieldWorks project by hiding some of the complexity of LCM. For functionality that isn’t provided here, LCM data and methods can be used directly via FLExProject.project, FLExProject.lp and FLExProject.lexDB; However, for long term use, new methods should be added to this class.

Usage:

from SIL.LCModel.Core.KernelInterfaces import ITsString, ITsStrBldr
from SIL.LCModel.Core.Text import TsStringUtils 

fp = FLExProject()
try:
    fp.OpenProject("my project",
                   writeEnabled = True/False)
except:
    #"Failed to open project"
    del fp

WSHandle = fp.WSHandle('en')

# Traverse the whole lexicon
for lexEntry in fp.LexiconAllEntries():
    headword = fp.LexiconGetHeadword(lexEntry)

    # Use get_String() and set_String() with text fields:
    lexForm = lexEntry.LexemeFormOA                                            
    lexEntryValue = ITsString(lexForm.Form.get_String(WSHandle)).Text
    newValue = convert_headword(lexEntryValue)
    mkstr = TsStringUtils.MakeString(newValue, WSHandle) 
    lexForm.Form.set_String(WSHandle, mkstr)

BestStr(stringObj)

Generic string extraction function returning the best Analysis or Vernacular string.

BuildGotoURL(objectOrGuid)

Builds a URL that can be used with os.startfile() to jump to the object in Fieldworks. This method currently supports:

• Lexical Entries

• Reversal Entries

• Wordforms

• Texts

CloseProject()

Save any pending changes and dispose of the LCM object.

GetAllAnalysisWSs()

Returns a set of language tags for all analysis writing systems used in this project.

GetAllSemanticDomains(flat=False)

Returns a nested or flat list of all Semantic Domains defined in this project. The list is ordered.

Return items are objects with properties/methods:

• Hvo - ID (value not the same across projects)

• Guid - Global Unique ID (same across all projects)

• ToString() - String representation of the semantic domain.

GetAllVernacularWSs()

Returns a set of language tags for all vernacular writing systems used in this project.

GetCustomFieldValue(senseOrEntryOrHvo, fieldID, languageTagOrHandle=None)

Returns the field value for String, MultiString and Integer fields. Returns None for other field types. languageTagOrHandle only applies to MultiStrings; if None the best Analysis or Venacular string is returned.

Note: if the field is a vernacular WS field, then the languageTagOrHandle must be specified.

GetDateLastModified()

GetDefaultAnalysisWS()

Returns the Default Analysis Writing System: (Language-tag, Name)

GetDefaultVernacularWS()

Returns the Default Vernacular Writing System: (Language-tag, Name)

GetPartsOfSpeech()

Returns a list of the Parts of Speech defined in this project.

GetWritingSystems()

Returns the Writing Systems that are active in this project as a list of tuples: (Name, Language-tag, Handle, IsVernacular). Use the Language-tag when specifying Writing System to other functions.

LexiconAddTagToField(senseOrEntryOrHvo, fieldID, tag)

Appends the tag string to the end of the given field in the sense or entry inserting a semicolon between tags. If the tag is already in the field then it isn’t added.

LexiconAllEntries()

Returns an iterator over all entries in the lexicon.

Each entry is of type:

SIL.LCModel.ILexEntry, which contains:
    - HomographNumber :: integer
    - HomographForm :: string
    - LexemeFormOA ::  SIL.LCModel.Ling.MoForm
         - Form :: SIL.LCModel.MultiUnicodeAccessor
            - GetAlternative : Get String for given WS type
            - SetAlternative : Set string for given WS type
    - SensesOS :: Ordered collection of SIL.LCModel.Ling.LexSense 
        - Gloss :: SIL.LCModel.MultiUnicodeAccessor
        - Definition :: SIL.LCModel.MultiStringAccessor
        - SenseNumber :: string
        - ExamplesOS :: Ordered collection of LexExampleSentence
            - Example :: MultiStringAccessor

LexiconClearField(senseOrEntryOrHvo, fieldID)

Clears the string field or all of the strings (writing systems) in a multi-string field. Can be used to clear out a custom field.

LexiconEntryAnalysesCount(entry)

Returns a count of the occurences of the entry in the text corpus.

NOTE: As of Fieldworks 8.0.10 this calculation can be slightly off (the same analysis in the same text segment is only counted once), but is the same as reported in Fieldworks in the Number of Analyses column. See LT-13997.

LexiconFieldIsStringType(fieldID)

Returns True if the given field is a simple string type suitable for use with LexiconAddTagToField(), otherwise returns False.

LexiconGetCitationForm(entry, languageTagOrHandle=None)

Returns the citation form for the entry in the Default Vernacular WS or other WS as specified by languageTagOrHandle.

LexiconGetEntryCustomFieldNamed(fieldName)

Return the entry-level field ID given its name.

NOTE: fieldName is case-sensitive.

LexiconGetEntryCustomFields()

Returns a list of the custom fields defined at Entry level. Each item in the list is a tuple of (flid, label)

LexiconGetExample(example, languageTagOrHandle=None)

Returns the example text in the Default Vernacular WS or other WS as specified by languageTagOrHandle.

LexiconGetExampleTranslation(translation, languageTagOrHandle=None)

Returns the translation of an example in the Default Analysis WS or other WS as specified by languageTagOrHandle.

NOTE: Analysis language translations of example sentences are stored as a collection (list). E.g.:

for translation in example.TranslationsOC:
    print (project.LexiconGetExampleTranslation(translation))

LexiconGetFieldText(senseOrEntryOrHvo, fieldID, languageTagOrHandle=None)

Return the text value for the given entry/sense and field ID. Provided for use with custom fields. Returns the empty string if the value is null. languageTagOrHandle only applies to MultiStrings; if None the default Analysis writing system is returned.

Note: if the field is a vernacular WS field, then the languageTagOrHandle must be specified.

For normal fields the object can be used directly with get_String(). E.g.:

lexForm = lexEntry.LexemeFormOA
lexEntryValue = ITsString(lexForm.Form.get_String(WSHandle)).Text

LexiconGetHeadword(entry)

Returns the headword for the entry

LexiconGetLexemeForm(entry, languageTagOrHandle=None)

Returns the lexeme form for the entry in the Default Vernacular WS or other WS as specified by languageTagOrHandle.

NOTE: using this function will lose any formatting that might have been present in the example string.

LexiconSetFieldInteger(senseOrEntryOrHvo, fieldID, integer)

Set the integer value for the given entry/sense and field ID. Provided for use with custom fields.

LexiconSetFieldText(senseOrEntryOrHvo, fieldID, text, languageTagOrHandle=None)

Set the text value for the given entry/sense and field ID. Provided for use with custom fields.

NOTE: writes the string in one writing system only (defaults to the default analysis WS.)

For normal fields the object can be used directly with set_String(). E.g.:

ObjectCountFor(repository)

Returns the number of objects in the given repository. repository is specified by the interface class, such as:

• ITextRepository

• ILexEntryRepository

(All repository names can be viewed by opening a project in LCMBrowser, which can be launched via the Help menu.)

ObjectsIn(repository)

Returns an iterator over all the objects in the given repository. repository is specified by the interface class, such as:

• ITextRepository

• ILexEntryRepository

Open a project in LCMBrowser to identify other repository names.

OpenProject(projectName, writeEnabled=False)

Open a project. The project must be closed with CloseProject() to save any changes, and release the lock.

projectName:

• Either the full path including “.fwdata” suffix, or

• The name only, to open from the default project location.

writeEnabled:

Enables changes to be written to the project, which will be saved on a call to CloseProject(). LCM will raise an exception if changes are attempted without opening the project in this mode.

Note:

A call to OpenProject() may fail with a FP_FileLockedError exception if the project is open in Fieldworks (or another application). To avoid this, project sharing can be enabled within the Fieldworks Project Properties dialog. In the Sharing tab, turn on the option “Share project contents with programs on this computer”.

ProjectName()

Returns the display name of the current project.
